because of the trigon operation, i continued to work very successfully for 32 years as a covert cia officer. a city on edge. a police shooting in milwaukee, wisconsin, brings protests and violence to city streets. we're covering the story. dramatic rescues in the state of louisiana. residents struggling. plus, more history is made in rio de janeiro. british runner mo farah stumbles and michael phelps wins his 28th medal. welcome to our viewers here in the united states and around the world. i'm george howell. "cnn newsroom" starts right now.

good day to you. in milwaukee, wisconsin, things are calming down at this hour after a night of violent protests sparked by a police shooting. an officer shot and killed an armed man during a foot chase. during the protests, one officer was hit in the head by a brick thrown into his squad car. police then moved in to clear the streets as you see here, but they say protesters set four buildings on fire. milwaukee's mayor spoke about the shooting. >> he was hit by two bullets, one in the chest, one in the arm. that individual was a 23-year-old man, has died. the officer was wearing a body camera. it is my understanding that the body camera was operating. because it involved the milwaukee police and because an individual was killed, the

investigation is being led by the state of wisconsin so the state of wisconsin will be the one that will have access to that film from the body camera and is the one that is now undergoing the investigation. as you all know from what happened from that point, things deteriorated. when i left the scene, which was probably a little after 5:00, there was still calm at that scene. later in the evening as we all now know, things got out of hand. >> mayor tom barrett of the city of milwaukee also saying three people have been arrested. we heard from a witness who says she does not believe the unrest is over in milwaukee. >> just basically awe struck and amazement. i never thought i would see my own city in a state of unrest to potential riot, you know? i just never thought i would see it. we're standing here speaking

with you, just heard gunshots maybe two to three blocks away. i feel maybe the bulk of the large incidents are over for the evening, but i definitely do not feel that this is over. >> the officer involved in the shooting has been placed on administrative duties while authorities investigate. cnn has a crew en route and in place there in milwaukee. our national correspondent ryan young, of course, will stay on top of this and bring you any new vemgts as we learn them here on cnn. moving on now to the state of louisiana under a state of emergency there for the next month due to heavy rains and deadly flooding there. three people have died and one person is reported missing. louisiana's governor calls the flooding a truly historic event and says that everyone needs to be in response mode. >> we have record levels of flooding along rivers and creeks, and because these are

record floods, we don't know how wide the water is going to get in those areas. we don't -- this is unprecedented so we don't have records that we can go back and see who all is going to be impacted. >> so far more than 1,000 people and roughly 100 pets have been rescued from these raging flood waters. cnn national correspondent laura sanchez has more for us from the flood zone. >> reporter: the flood waters are starting to recede in some parts of louisiana. would era getting a clear picture of the extent of the damage, just how bad this flooding was, how strong these waters were. over to the left of me, we're in an industrial yard in amy, louisiana. that's a body shop. that truck was on the other side of that building. there was a tractor that was helping people get across this flooded area to get to their homes and come back. the truck actually got stuck in the water and had to be pulled

out itself. you can also see pieces of asphalt, huge pieces of asphalt that have just been lifted off the ground and tossed about like pieces of paper onto the street. and i want to point something out. you see it across the street here in that area just off the street. that white pickup truck, that was actually a man that was trying to cross the road while it was flooded out. he clearly did not make it across. he had to be rescued by officials. one of the 1,000 rescues that firefighters, paramedics and other emergency officials have had to make here in louisiana because of this devastating flooding. the last thing i want to point out across the street. that trailer, i spoke to the guy that lived in that trailer. he kept it across the street here in the industrial park. fortunately he didn't spend the night here in the industrial park. he said it ran more than 120 yards and got smashed, flattened against the trees there. i asked how he felt seeing his home flattened and his state in disarray. here's what he said? >> it's terrible.

the gentleman that has that tractor right there, he lost his house in the flood back in march. he just a couple of weeks ago got his house back in order and he's lost -- he's lost everything. he had six, eight feet of water in his house. that's terrible. i mean, there's people that's just, you know, it's a sad thing to see. >> reporter: the major concern now are the cities and towns that are south of here because all of this water that was here has continued moving in that direction. the other question is when is the rain finally going to stop? it had settled down here a couple of hours ago, now it's falling again. experts tell us it will continue at least until monday. >> national correspondent boris sanchez there. asking the question when is the rain ever going to stop. derek van dam is here. derek, from what you've seen, it is a bad situation. is it going to get worse? >> it's been consistent since thursday evening local time. there is some light at the end of the tunnel, george. i got to show you an absolutely

remarkable video coming from a rescue effort in baton rouge, louisiana. i'm going to let you listen to this. this woman survived a near drowning in this flood water thanks to some very courageous men. the woman's convertible was about 2/3 submerged. she can be heard asking for help. >> we're breaking the window. the car keeps sinking and one of the men jumps from the both on to the car, starts to tear through the convertible's fabric roof just moments before he pulls the woman from the sinking vehicle. watch this. unbelievable. and, george, it actually is more incredible what he does now. she calls and pleads for him to go underwater to look for her dog who is still trapped in the vehicle and comes up

successfully with the puppy. who is that man? i would love to interview that man. thank goodness for the volunteers and the authorities out there doing these rescues. there's been over 1,000 swift water and high water rescue attempts already successful. unfortunately, there have been fatalities but this is, again, showing you the kind spirited nature of complete strangers helping the communities across southern louisiana. here's the latest satellite loop. i want to show you the bulk of the precipitation. there's louisiana, there's mississippi, there's texas. the good news is as i mentioned a moment ago that the bulk of the precipitation is moving away from the affected flood areas, but not before considering or not before producing a considerable amount of rainfall. over 680 millimeters. that's roughly 26 inches of rain. here it is. the future radar going forward over the next 24 hours. you can see that more of a sporadic nature of the heavier rain showers indicated with the

yell lows and the reds. they become less and less prominent as we go forward in time. that's because the system is starting to break apart and pull away from the region. i want to show you a flash flooding that was captured by this river gauge. notice the spike in the river levels there for the comot river in central louisiana. that rose 25 feet in 12 hours breaking previous flood stage records. i'm getting my tongue twisted here. flash flooding occurring across this region. not good when you see call centers like this, emergency call centers. these individuals, the authorities actually had to evacuate the 911 call center there because of rapidly rising waters. george. >> what an amazing video, wasn't it? just to see the woman pulled from the car in the nick of time. >> thankfully he was there. derek, thank you.

aiming for the gold, rio olympics day eight wrapped up on saturday. it was a good day for michael phelps winning yet another gold medal. the most decorated olympian ever. he won the men's 4x100 medley relay. this makes for phelps 23rd olympic gold medal. on the track british runner mo farah recovered from a fall to take the gold in the men's 10,000 meter race. let's go live to rio and what to expect from day nine. kristina mcfarland is live, let's start with you. let's start with mo farah. what a performance. not only did he break out from the back of the pack but he recovered from a fall to defend his 10,000 meter olympic title. >> reporter: yeah, that's absolutely right, george. it was not so much the fact it was more fantastic farah.

surely only mo farah can fall during a race and go on and win the 10,000 meter. he was clipped and went down. in fact, it was his teammate he managed to collide with. he went on and powered clear of the field in the final 100 meters to win it in a time of 27:05 amidst the kenyans, ethiopians, many runners considered to be the best in the world. remember, he'll be back on wednesday to defend his 5,000 meter title. if he wins that, he'll become the first man since the flying finn in 1976 to retain his two olympic discipline titles. it really was incredible to watch last night. >> i'm an old track runner myself. nothing like these guys. i appreciate the craft. to recover from a fall and to still win, that's just incredible. let's also talk about michael phelps in the pool and the question, will this be his last

olympics? >> reporter: that is a good question, george. we're expecting him to have a press conference later today where he may reveal all. he has hinted, of course, in the past few days that he thinks this will be it for him, but remember he said that at the end of london 2012, didn't he? and then he came back. on saturday night it couldn't have ended any other way. gold number 23 for phelps. 28 now in total after winning the 4x100 meter medley relay and arguably cementing his legacy as the greatest ever. perhaps we should have seen this one coming because the u.s.a. have never failed to win this particular event in olympic history, would you believe. phelps, of course, the baltimore bullet, handed their anchorman the lead going into the fourth leg. from there, the united states never gave it up. so we'll have to wait and see. fingers crossed that phelps may still continue in the swimming pool but, as i say, the greatest olympian really of all time. it's likely he may bow out later today. >> wow. and looking ahead now.

let's talk about usain bolt and the challenge that he faces with rival justin gatlin. from what we've seen so far in the qualifying heat is gatlin even considered a challenge? >> reporter: oh, absolutely he's considered a challenge, george. he's run the fastest time this year, and this is the showdown really that everyone is waiting for. of course, sunday is all about usain bolt. he's looking to do the triple triple for the first time in history. remember, that's the 100 meters, the 200 meters and the 4x100 meter relay. today is going to be the first leg of that. he runs later today around 7:00 p.m. local time tonight. yesterday on saturday i had a chance to see him and gatlin run in the heats. usain bolt running the fourth fastest time in the heat at 10:07 while justin gatlin had the fastest time, 10:01. so as i say, this is going to be the showdown, it's going to be the head to head. it's good versus evil as people

keep calling it here, however, don't forget that bolt does hold the world record and that he has had a season of injuries. this is going to be psychological warfare out there in the 100 meters. very exciting. >> indeed. christine mcfar land, a little envious of your role there. watching history as the olympic athletes take to the track and field and the pool. thanks for your reporting. we'll stay in touch with you. let's talk medal count today. the u.s.a. won its 1,000th gold medal of all time on saturday. the first country to do that in rio alone there they have 24. that nearly doubles the next closest nation, china, with 13. brittain pulled away with third in third place with a total of 30 medals and japan still fourth in the overall count with 24. one behind germany pushing them to fifth in the standings. of course, for more action, more highlights, for more stories you can go right to cnn.com/olympics

for everything. you're watching "cnn newsroom." still ahead, the syrian city of manbij, celebrations there and the chance to stoort life again after isis is pushed out. why manbij is crucial. plus, thousands of venezuelans crossed into colombia to buy food and other items. what might have led the venezuelan president to change his mind after he closed the border last year. this is "cnn newsroom."

welcome back to "newsroom." authorities are looking for whoever shot and killed an imam and assistant killed near a mosque. sara ganim has more details from the scene. >> reporter: new york city police could be fi-- done confirming that an imam and his assistant was killed. a man approached them from behind shooting them both in the head. investigators still trying to figure out exactly what happened. they are looking at surveillance video that shows a man with a

gun running from the scene. no arrests have been made, but witnesses are also being interviewed. investigators say there's nothing that preliminarily indicates that these two men were targeted, but investigators are also looking to see if there was an earlier dispute at the mosque that may have led to a shooting. that's according to a law enforcement source. as this investigation begins you can see that the local community has gathered. news of the shooting garnered significant reaction from the community here. obviously it's a very scary thick to think that a local religious leader can be gunned down in the middle of the street in broad daylight and there are many concerns from people in this community who have gathered calling for justice and also remembering these men. some people have told me that their local imam was beloved here. he had just eulogized someone else the other day and he was a very nice guy, very well known in the community. had kids. frequented the stores. and so obviously that showing of

support here in queens as the investigation continues to try and figure out what happened. sara ganim, cnn, queens, new york. >> sara, thank you. more than a dozen children are dead after two saudi-led airstrikes hit schools in yemen. the first strike hit a private school killing at least 10 children, wounding 28 others. the students were all between the ages of 8 years old and 15 years old. another airstrike struck a nearby school killing 4 children there and 3 adults. u.n.-led peace talks came to a dead end last week resulting in fierce clashes throughout yemen. people in the syrian city of manbij now have a sliver of hope that their lives will recover. rebel fighters backed by the united states have forced isis out of that city. the u.s. is hoping to acquire key intelligence loeft behind by that terror group, and

washington now wants to use manbij as a spring board to retake raqqah, the de facto capitol of isis. our senior international correspondent ben wideman has this report. >> reporter: with the fall of manbij, isis has lost another strong hold in syria. the latest in a string of towns and cities in iraq and syria where isis's black banner has been torn down but inhab tants of this syrian town, it was a relief to be liberated by the u.s.-supported syrian democratic forces, a coalition of kurdish and arab fighters. the inhabitants of the town enjoying relieve from isis's draconian regime. some men took the opportunity to shave off their once mandatory beards and men and also women had the opportunity to enjoy a smoke in public for the first time in years without fear of a lashing. some women took the opportunity

to burn their head to toe nikabes, the stifling garment required by isis of all women who wanted to go out in public. isis has now lost an important supply route between the turkish border and its de facto capitol of raqqah, but this is just one battle won. the war against isis is still far from over. isis still controls mosul, the second largest city in iraq, and it still controls large tracts of northern syria. ben wideman, cnn, istanbul. ben, thank you. in just a few hours' time the nice football team will honor men. on sunday with their match players of the ojc nice will wear a special jersey with the

names of the 85 people killed in the shape of a heart. the team is also asking fans to wear white shirts. thousands of desperate venezuelans crossed into colombia on saturday after the two countries agreed to at least temporarily reopen that border. venezuelans are anxious to buy food and other basic supplies, items they can't find or afford in their country. falling oil prices have contributed to a severe recession in venezuela. they want to remove the president this year. rafael romo is covering this. >> reporter: hours before sunrise people were already standing in line at the border. tens of thousands of venezuelans were desperate to cross into colombia for the first time in ten years. the border should always be open says this woman.

venezuelan president ordered the $2200 border closed last year. he met with colombian president thursday in venezuela to announce a re-opening of the border. we will open the border in an orderly, controlled, and gradually controlled way, president santos said. which means this is not a permanent reopening. for now the border will be open for 15 hours a day and only for pedestrians. while 28,000 venezuelans crossed into their country on saturday alone. authorities briefly opened portions of the border several times in the last few weeks, but this is the first time it reopens as part of the bi-national agreement. for the venezuelans, it was mainly an opportunity to buy basic food products and toiletries that have been scarce in venezuela for years. later in the day they returned home carrying bags, packages and

boxes full of food and other items. others flocked to pharmacies to get medicines that are nowhere to be found in venezuela. some even carried tires. this woman said she felt like taking pictures at this colombian supermarket where we found her. all she sees back home are empty shelves. after almost a year of suffering shortages, the abundance of essential grocery store items in colombia was overwhelming. rafael romo, cnn. you're watching "cnn newsroom." still ahead, donald trump has his own idea of what to do with a prison that others want to close. why experts doubt that would ever work. and michael phelps is saying good-bye to swimming from the top of the medal podium. a look back at his legendary career. we are live in the united states and around the world at this hour. you are watching "cnn newsroom."

welcome back to our viewers here in the united states and around the world, you are watching "cnn newsroom." it is good to have you with us. i'm george howell with the headlines we're following for you this hour. legendary swimmer, michael phelps, won gold in his final olympic race on saturday. he swam in the 4x100 meter medley relay. that makes gold medal number 23 for the american. by far the all-time record. soaking rains have created massive flooding across parts of the united states and the state of louisiana. three people have died and one person is missing. louisiana's governor declared a

state of emergency on friday calling the flooding a truly historic event. in northern yemen two separate airstrikes by saudi-led coalitions have led to more than a dozen children killed. according to yemen's health ministry, the first strike killed at least 10 children after hitting a school and wounded 28 others. another airstrike struck a nearby school killing four children and three adults. new york police are on the lookout for whoever shot and killed an imam and his assistant in broad daylight. they were both shot in the head outside of a mosque after prayers on saturday afternoon. police say nothing in their early investigation indicates that the men were targeted. in the state of wisconsin milwaukee police say that they are restoring order to the streets after a night of violence over a police shooting. crowds gathered on saturday night on the streets hours after police shot and killed an armed

man during a foot chase. as officers tried to break up the protest, things turned violent. people turned buildings on fire and one officer was hit in the head by a brick thrown into his windshield. earlier milwaukee's mayor spoke about a shooting and what led up to it. listen. >> this stop took place because two officers who were there to make sure that there's order in this neighborhood, they felt there was suspicious activity going on, as it turned out, two individuals, a gun was a stolen gun. the officers didn't know it at the time, but there were 23 rounds in that gun. 23 rounds in the gun that that officer was staring at. i want to make sure we don't lose any police officers in this community. and that's something that has to be a concern as we stand here tonight. >> the mayor also said that police have arrested three people. we'll stay on top of this story.

america's choice 2016, donald trump lashing out now at "the new york times" after their reporters wrote an article saying advisors believe it may be impossible to save trump from his own mistakes. u.s. republican presidential candidate fired back then on twitter calling the times, quote, a failing newspaper of fiction. trump's grievance is not just with the times. he seems to even hold a lower view for the reporters than he does of his rival hillary clinton. listen. >> i'll tell you honestly, i'm not running against crooked hillary clinton, i'm running against the crooked media. that's what i'm running against. i'm not running against crooked hillary. >> u.s. president barack obama

has long wanted to close the detention center at guantanamo bay, cuba, but donald trump has another idea entirely. a pentagon correspondent barbara starr has details on that for us. >> reporter: donald trump has new thoughts on how if elected he might send u.s. citizens accused of terrorism to the military prison at guantanamo bay. >> would you try to get the military commissions, the trial court there to try u.s. citizens? >> well, i know they want to try them in our regular court systems and i don't like that at all. i don't like that at all. i would say they could be tried there. that would be fine. >> reporter: the law that tries people says they can't be tried at gitmo. >> he would have to work to get different laws. >> reporter: would that work? >> that would be suspect. why? because current u.s. courts are fully open and capable to

provide the full panopoly for the guarantees. >> reporter: some of trump's ideas, including water boarding, are raising critical questions about the authority of the president to carry out troops to carry out actions. the u.s. military has the duty to disobey illegal orders even when they come from the president. >> military adherence to civilian command and control is a bedrock principle of the u.s. military, however, the u.s. military swears to protect and defend the u.s. constitution first and foremost. >> reporter: but trump says he expects to be obeyed by the troops, even on water boarding. >> they won't refuse. they're not going to refuse me, believe me. >> reporter: a former military lawyer says trump should be refused. >> there's no moral dilemma of a military member to think, well, maybe this is lawful. no, it's illegal.

>> reporter: general joseph dumford has stayed out of the fray. >> one of the things that makes me proud is that we represent the values of the american people. that's what we have done historically, that's what we expect to do in the future and, again, that's what makes me proud to wear this uniform. >> that was cnn's point gone correspondent barbara starr reporting for us. donald trump has been under fire for refusing to release his income taxes but his running mate, republican vice presidential candidate mike pence is taking a different approach. pence says he will release his own tax returns before election day in november. he promises they will be, quote, a quick read. democrat hillary clinton has released tax returns going back years. so has her running mate tim kaine. the virginia senator and vice presidential candidate hit trump hard saturday for not disclosing his taxes. kaine said even a president who

resigned in disgrace allowed voters to see how much he paid in income taxes. >> even richard nixon released his tax returns to the public when he was running for president because he said, as has every major nominee in the party since, the americans should see who i have connections with, they should see if i'm paying the taxes that support our veterans, that support our military. >> donald trump says that he will not disclose his taxes while they are being audited but there's no law that is keeping donald trump from doing so. former cuban leader fidel castro celebrated his 90th birthday on saturday. he made a rare appearance at festivities in havana, cuba. sitting between venezuelan president nicholas maduro and his brother president raul castro. they say he survived more than,

get this, 600 assassination attempts. however, that number is impossible to confirm. this is "cnn newsroom." still ahead, almost 50 years ago terror struck the olympics and why this man will never forget a minute of that nightmare. stay with us. and dad forever, do you?" "boo!" (laughs) "i'm making smoothies!" "well...i'm not changing." "so, how can i check my credit score?" "credit karma. don't worry, it's free." "hmmmm." "credit karma. give yourself some credit."

for nearly two decades now the name michael phelps has been synonymous with swimming. he appeared in his first olympics 16 years ago and since then he's had one of the most prolific careers of all time. now he's saying good-bye from where we've seen him start and where he is now, the top of the podium. our andy scholz looks back at phelps' career. >> reporter: michael phelps entered the global swimming stage at the age of 15

qualifying for his first olympic games. since that time he has been the most dominating force the world of swimming has ever seen competing long enough to inspire a new generation of swimmers. look no further than american gold med allest katie ledecky. here she posed with phelps as a 9-year-old. ten years later they're winning gold together. >> it's pretty incredible to have helped kids go after their dreams and their goals. >> i'm seeing him in a different capacity. an athlete, a fierce competitor but also michael phelps the mentor. he has just become a role model to so many people. >> sydney, athens, beijing, london, then his first retirement. phelps did not just come back for a farewell tour at the rio games, he crushed it winning five gold medals. he has now stood atop the podium 23 times. >> this is a young person's sport. this is a sport where teenagers

are winning gold medals. he's 31. in baseball years that's probably 55, and the thought that he can still be at the top of the world on this at this point is extraordinary. >> on top of the world, in the water, phelps sometimes struggl struggled. controversy, dui arrest, rehab in 2013. this is it for phelps. couldn't have written a better ending. now a father. his fiance nicole johnson, 3-month-old son boomer. >> they've adjusted themselves so well. they have a very special loving bond between the three of them. i think michael's in a really good place right now. >> reporter: what's next for phelps? he says he's looking forward to spending time with his family. he'll continue his work with the michael phelps foundation which helps kids learn to swim. phelps also uses his free time to encourage change in the sport of swimming.

>> if michael phelps speaks out about doping the ioc will listen in a way they're not going to listen to anyone else. maybe at the end of the day that's michael's legacy, the combination of bringing children to the sport of swimming and trying to clean up the sport of swimming in doping and all the bad things that's happened. >> he's changed the sport and he will continue to change it even past his retirement. >> it is finally setting in more and more that some of the things that i've been able to accomplish throughout my career. i'm not only changing the sport, i'm seeing it firsthand. i think that's something that is really rewarding. >> sunday's biggest event is the men's 100 meters where superstar usain bolt will look to defend the first of three sprinting titles there. the men will also run the 400 meter while the women will compete in the marathon and the triple jump. then, on the tennis court brittain's andy murray will try to defend his olympic title from the resurgent argentinian juan

martin del porto. women's and men's teams will also compete. golfers will play their final round in the men's tournament. the president of track and field's governing body says jamaican's sprinter usain bolt is an all-time athlete. he's going after his triplepete of the 100, 200 and 400 meter sprints. he's compared to one of the greatest competitors ever. he spoke to cnn's amanda davis. >> reporter: have you tried to persuade usain bolt to change his mind about the suggestion of retirement? >> no, i wouldn't begin to do that with an athlete, but i have had conversations with usain about a role beyond his retirement whenever that happens. i hope it's not for some time, but i -- no sport should allow or be comfortable about such an

extraordinary athlete just walking away. we need to keep him involved. >> reporter: if he was able to pull off the triple triple, how big of an achievement would that be? >> i think it's extraordinary. it's frankly extraordinary. the great thing about usain bolt is he has -- we're very proud to have him in our sport but he's actually gone almost beyond, you know, just the confines of track and field. wearing my london hat for just a few moments, when we started bidding for the games in 2005 i spent a lot of time in 2003, spent a lot of time in schools talking to young people. i actually asked them what sports they did and who they wanted to be. they all wanted to be david beckhams and roger federer's. three years later they wanted to be usain bolt. that's been the difference. i can't think of another athlete since muhammad ali that has so captured the public imagination and with such global depth of

affection. >> very interesting comparison there. certainly fair to say that rio has been secure so far, but we look back almost half a century ago to the most terrifying hours in olympic history. that's ahead here on "cnn newsroom." the decision to ride on and save money. he decided to save money by switching his motorcycle insurance to geico. there's no shame in saving money. ride on, ride proud. geico motorcycle, great rates for great rides.

welcome back to "newsroom." the capital of manila where heavy rains have caused flooding and lots of problems in several areas. more rains are expected in the coming hours. our meteorologist derek van dam is following that story from the international weather center. derek, what's the latest? >> george, this is called the southwest monsoon, an annual occurrence across this part of the world. doesn't make it any less of a nuisance or dangerous to say the least. take a look at these images. this is unbelievable stuff. it reminds me of what is happening in the southern sections of the united states in terms of the depth and the widespread nature of the flooding. this is a suburb of manila. we talk about this being the wettest time of the year for the northern philippines, and specifically across luzane island.

manila's climatological average puts august right smack dab in the middle of the wettest part of the year. this is the southwest monsoon. we're talking about rainfall totals on average this month roughly about 486 milliliters to be precise. take a look at what's happening with the satellite. you can see how active it is. here's liuzanne, manila. you can see the cloud cover and the rain continues to move through this area. calculated a few rainfall totals for the past few days. manila has seen just under 200 millimeters. in an area north called iva, -- iba, philippines, just over 300 millimeters. monsoon is associated with a wind pattern. that pulls in moisture from the south china sea. what's interesting is often when

we get a typhoon or tropical system across the pacific. we pull more moisture across this area into the philippines. what's that on my computer graphics there? well, indeed, tropical storm chantu rotating about the south pacific. >> george, thank you. we'll stay in touch. i want to consider about what could be the darkest hour in olympic history. it came 44 years ago when terrorists kidnapped and killed 11 israeli athletes and officials. warren lieberman looks back at the massacre in munich. >> reporter: these are the members wanted to be remembered. suberi recalls the pride he felt competing. calls every moment of those games, even the moments he wishes he could forget. the munich massacre on september 5th, palestinian terror group called black september took part

of the israeli team hostage in the village. suberi, a wrestler, was the only one to escape. >> translator: i saw an opening. the ak rifle was here. i pushed it away from my stomach. he never chased me, he shot. i never looked behind, left or right, i just ran. >> reporter: the memory haunts him to this day. now for the first time the international olympic committee has created a memorial sight in the olympic village to remember all olympians who died during the game, including the 11 israelis murdered in munich. they will always be suberi's teammates. >> translator: i will remember every second until i die. it's in the a dream. it's like i feel every second until this moment. something like that is impossible to forget. >> reporter: despite the painful memories, suberi still reveres the olympic games for what he says they are, a chance to unite the world.

>> translator: they once asked me if they should have continued the games and i said, yes. it's for the whole world and it continued. it's a festival that gives good feeling to the whole world. >> reporter: before leaving for the olympics, they paid their respects. this man laid a wreath at his site. this is gad suberi's nephew. he will compete in wind surfing. perhaps that's the strongest way of remembering what happened. by carrying the name of a survivor to the olympic games. >> certainly good to remember the past, to be thankful for the present. finally, nature is putting on quite a show in the northern hemisphere through the weekend with an annual meteor shower. nasa astronomers say it's even more spectacular than usual. i want to show you. ♪ ♪

a police-involved shooting in the united states followed by protests and several fires. we have the very latest from milwaukee, wisconsin, ahead. plus, little or no relief from deadly flooding in the state of louisiana. we'll show you some of the dramatic rescues that are still being made. and michael phelps saying that he is finishing his olympic career. what a career it was capped with one more gold medal. live from cnn world headquarters in atlanta, welcome to our viewers here in the united states and around the world, i'm george howell. "cnn newsroom" starts right now.

it is 5:00 a.m. on the u.s. east coast, and in the state of wisconsin, milwaukee police say things are calmer this hour after a night of violent protests sparked by a police shooting. crowds gathered there just hours after police say an officer shot and killed an armed man during a foot chase. during the protests someone hit an officer in the head with a brick. police then moved in to clear the streets, but things got out of control, they say, and protesters set four buildings on fire. milwaukee's mayor spoke earlier about those disturbances. listen. >> if you're a mother who is watching this right now and your young son or daughter is not home and you think they're in this area, get them home right now. get them home right now. if you love your son, if you love your daughter, text them, call them, pull them by the ears and get them home. >> mayor reaching out to people there. let's get the very latest from

reporter sheldon dutez with our affiliate wisn in milwaukee. >> reporter: fire crews were working in this neighborhood well into the early hours. just before 3:00 this morning crews still on the scene of this auto parts store which was set on fire late saturday night. crews were out here for several hours trying to get those flames and that smoke under control. it was not until a little before 3:00 local time that they were able to get everything in that building under control. it's the o'reilly auto parts. now this is one of three fires that were smoldering in this particular neighborhood. a beauty supply right next door to that auto supply building also set on fire and there was a small fire at a bank a little bit further down the block. now police had this intersection and the area around it blocked off for several hours tonight as crews were battling multiple fires in this section of milwaukee. now crews had their helmets on,

they had their shields on, but there were no confrontations with police, at least from what we could see. a couple people were taken into custody at this location. as far as the reason why they were taken into custody, that's something that we are still working to find out. in milwaukee, i'm sheldon dutez. we also have our national correspondent ryan young there on the scene and ryan will bring developments here as we get more information from milwaukee, wisconsin. now to the u.s. state of louisiana where heavy rain and deadly flooding has left communities underwater. three people there have died. one person is reported missing. louisiana's governor declared a state of emergency on friday calling the flooding truly historic. boris sanchez has more now from the flood zone. >> reporter: some of the flood waters are starting to recede in louisiana. we're getting a clear picture of the extent of the damage and just how bad this flooding was,

how strong these waters were. i want you to take a look to the left of me. we're in an industrial yard in amy, louisiana. that's a body shop. you see that pickup truck crushed, flipped over. that truck was on the other side of that building. there was a tractor in this area earlier that was helping people get across this flooded area to get to their homes and come back. the truck actually got stuck in the water and had to be pulled out itself. you can also see pieces of asphalt, huge pieces of asphalt that have just been lifted off the ground and tossed about like pieces of paper onto the street. i want to point something out. you see it across the street in that area just off the street, that white pickup truck, that was actually a man that was trying to cross the road while it was flooded out. he clearly did not make it across. he had to be rescued by officials. one of the 1,000 rescues that firefighters, paramedics and other emergency officials have had to make here in louisiana because of this devastating flooding. the last thing i want to point out across the street, that trailer.

i spoke to the guy that lived in that trailer. he kept it across the street here in the industrial park. fortunately he didn't spend the night here last night. he said it rammed 120 yards and got smashed, flattened against the trees over there. i asked how he felt with his home flattened and his state in disarray. here's what he said. >> gentleman just has that tractor right there, he lost his house in the flood back in march. he just a couple of weeks ago got his house back in order and he's lost -- he's lost everything. he had six, eight feet of water in his house. that's terrible. i mean, there's people that's just -- you know, it's a sad thing to see. >> reporter: the major concern now are the cities and towns that are south of here because all this water that was here just continued moving in that direction. the other question is when is the rain finally going to stop? it had settled down here a couple of hours ago. now it's stalling yet again. experts tell us they'll continue

at least until monday. >> cnn national correspondent boris sanchez asking the question when will it end. derek, it doesn't look like it will be over soon. >> the bulk of the rainfall looked as if it was moving on. now just in the past two hours or so, some of the most saturated areas have a resurgence of moisture. first, george, i want to show our viewers and yourself some very compelling video coming out of baton rouge. this is a rescue just in the nick of time. this woman survived a near drowning in baton rouge thanks to some courageous men in a boat who arrived to get her. >> oh, my god, i'm drowning. >> we're here. >> she's asking for help. she's drowning. this car kept sinking. one of the men, again, you can see him here trying to puncture a window to access the woman. he jumps onto the car, starts to tear through the convertible's fabric roof. what you're about to see here is absolutely incredible.

30 seconds later it would have been a whole different story and, george, it even goes on from here. this very courageous man, i wish we could interview him now. he went on to save this poor woman's dog who was still stuck within the submerged car. watch this. wow. that video just speaks a thousand words. we have to tip our hats to the authorities and to volunteer rescue individuals saving countless lives. there's already been over 1,000 swift and high water rescues in louisiana alone. here's what i was talking about, the recent flare-up of rainfall. this is the latest watches and warnings from the national weather service. baton rouge flood warning as we speak from interstate 55 to the west. that's the area we're concentrating on right along and parallel to interstate 10.

see the red shading there, that is a flash flood warning. it has been going on through the overnight. this is the gulf coast. new orleans is dry. this is the area that has been hardest hit. again, just within the past hour or two, a flare-up of moisture into this area means that additional rainfall and fairly heavy rain over the next few hours for that particular location. so we're going to continue to monitor for the potential of flash flooding, at least through this morning. look at these rainfall totals. oh, my goodness. almost 27 inches of rain in brownsfield, monticello. also very high rainfall totals for you. this is since thursday evening. our forecast radar going forward over the next 12 hours shows the rain starting to disperse, okay? we don't see the heavy oranges and yellows which indicate the heaviest precipitation so we're going to start to see the intensity break apart once the ban of heavy rainfall finally

starts to go back. this is the komac river. that rose 25 feet in 12 hours. this is scary, too. think about this, in livingston, louisiana, the one area you're supposed to have authorities, you call the 911 centers to ask for emergency help. well, this particular emergency call center had to be evacuated with all personnel because water was rapidly rising into this particular building. so, george, twhaent video just astounding to see something like that. and to be there in a moment's notice and to capture it all on video like that. that is why i'm in this news business. >> you know, there are a lot of people today who i know are going to want to talk to that guy. >> including myself. >> yeah, me, too. yeah. thank you. all right. day eight of the rio olympics

wrapped up on saturday, and michael phelps finished in true olympic style. the most decorated olympian ever. he took gold with his u.s. teammates in the men's 4x100 meter medley. phelps says he won't compete in the 2020 tokyo olympics, but he did come out of retirement to compete in rio so we'll have to wait and see. with his latest win though phelps now has 23 olympic gold medals. the u.s. was also victorious in the women's 4x100 meter medley as well. simone manuel anchored the u.s. team as australia took silver and denmark bronze. with that win the u.s. earned its 1,000th gold medal in modern era summer olympics. in track mo farah won the men's 10,000 meter. he's the first track athlete to win three gold medals. for more of what to expect on day nine, let's bring in

kristina mcfarland. it's good to have you, let's start with mo farah. not only did he break out of the back of the pack but he also recovered from a fall. >> reporter: that's absolutely right, george. surely only montpelier farah c and go on to win the 10,000 race. he fell during the beijing games and the world championships last year and he got up and won those as well. mid race in this race he was clipped by one of the runners, it was his teammate and he got back up and powered clear of the field in the final 100 meters to a time of 27:05 for gold. you know what's extraordinary in this, george, he was up against the kenyans, ethiopians who run as a pack. all of them trying to intimidate him. it was water off a duck's back.

what we saw last night, sheer dominance. this is a man who knows when to move, he knows when to challenge and when to hang back. it was just a master class. he'll be back on wednesday to defend his 5,000 meter title, and if he wins that he'll become the first man since the flying finn in 1976 to retain his two olympic distance titles. >> just fascinating. let's talk about michael phelps in the pool. the question, history made for sure, but will this be his last olympics? >> reporter: that's a good question, george. you know, after winning the 100 meter butterfly on friday, he said he was absolutely not ca y carrying on. he confirmed on facebook live saturday morning saying tokyo 2020 was not for him. he appears to be adamant that this is his last -- his last event, but, you know, the reason we have obviously problems believing him because in london 2012 he retired and then he came

back and we're expecting a press conference later today where we may hear official confirmation of that. i have a really good stat to tell you, george, about michael phelps here. if michael phelps were a country, he'd actually rank 12th in the world at the medal table since 2004. that is how dominating he has been. no one doubted it would be med tall 23 last night, 28 in total after winning the 4x100 meter medley cementing surely his place as the greatest ever. but, you know, for this particular event, we shouldn't have expected anything less than gold because the u.s.a. have never failed to win this particular event in olympics history but phelps, of course, the man of the night. >> very interesting stat to share with us. obviously we'll be looking ahead to see what happened with justin gatlin and usain bolt. thank you so much for your reporting. let's talk just a bit more about michael phelps. for almost two decades the sport of swimming has revolved around its greatest star and be now he

says that he's saying good-bye after five olympics and a career like no other. our andy scholz takes a look back. >> reporter: michael phelps entered the olympic scene at the age of 15. since that time he has been the most dominating force the world of swims has seen competing long enough to inspire a new generation of swimmers. look no further than american swimmer katie ledecky. ten years later they're winning gold together. >> it's pretty incredible to have helped kids go after their dreams and their goals. >> i'm seeing him in a different capacity, an athlete, a fierce competitor but also michael phelps the mentor. >> he has just become a role model to so many people and taking swimming to a sport, well, that's just an olympic sport, now it's cool. >> sidney, london, athens, and

then retirement. he did not come back just for a farewell tour, he crushed it. winning five gold medals, he has stood atop of the podium 23 times. >> this is a young person's sport. this is a sport where teenagers are winning gold medals. he's 31. in baseball years that's probably 55. and the thought that he can still be at the top of the world at this point is extraordinary. >> reporter: on top of the world in the water phelps sometimes struggled out of the pool. controversy, two dui arrests. after that he emerged a 234u6ne ability to compete. he's now a father. his fiance nicole johnson and his 3-month-old son boomer. >> they've adjusted very well. they have a very special loving bond between the three of them. i just think michael's in a really good place right now. >> reporter: what's next for phelps? he's looking forward to spending

time with his family. he'll continue his work with the michael phelps foundation which helps kids learn to swim and be safe around the water. perhaps phelps will use his free time to encourage change in swimming. >> if michael phelps speaks out about doping the ioc will listen in a way they're not going to listen to anyone else. >> maybe at the end of the day that's michael's legacy, bringing kids to swimming and trying to clean up swimming in terms of doping. >> he's changed the sport and he will continue to change it even past his retirement. >> it is finally setting in more and more that some of the things that i've been able to accomplish throughout my career, it's -- you know, in wanting to change the sport, i'm seeing it firsthand and i think that's something that is really rewarding. >> olympic greats. we're following the story of an imam and his assistant dead after an ambush in new york. the details on that fatal

shooting as police search for suspects. also, this special cuban cigar is for a very special occasion. we'll show you who blew out the birthday candles next. hey, you're clarence! yes, sir. you know, at the model year end clarence event, you can get a great deal on this 2016 passat. steve. yeah? clarence is on a roll. yeah. i wish they'd name an event after me. same here. but the model year end becky event? that's no good... stevent! that's just vandalism. whatever you want to call it, don't miss the volkswagen model year end event. hurry in for a one-thousand dollar volkswagen reward card and 0% apr on a new 2016 passat. lots of vitamins a&c, and, only 50 calories a serving... good morning, indeed. v8.

welcome back to "cnn newsroom." i'm george howell. police are searching for whoever killed an imam and his assistant near a mosque. our sara ganim has details for us from the scene. >> reporter: new york city police confirming that a queens imam and his neighbor were both gunned down leaving a mosque on saturday afternoon following prayers as they walked down the street towards home. a man approached them from behind shooting both in the head. investigators here at the scene still trying to figure out exactly what happened. say they are looking at surveillance video that shows a man with a gun running from the scene. no arrests have been made, but witnesses are also being interviewed. investigators say there's nothing that preliminarily indicates that these two men were targeted, but investigators are looking to see if there was an earlier dispute at the mosque that may have led to a shooting. that's according to a law enforcement source.

and as this investigation begins, you can see that the local community have gathered. news of the shooting garnered significant reaction from the community here. obviously it's a very scary thing to think that a local religious leader could be gunned down in the middle of the street in broad daylight and there are many concerns from people in this community who have gathered calling for justice and also remembering these men. some people told me that the local imam was beloved, that he had just eulogized someone else the other day and he was a very nice guy, very well known in the community, had kids, frequented the local stores and so obviously that showing of support here in queens as the investigation continues trying to figure out what happened. sara ganim, cnn, queens, new york. >> sara, thank you. new york police are stepping up patrols at the mosques.

they say there are no threats but they're adding security as a precaution. america's choice 2016. "the new york times" is reporting that some of donald trump's advisors believe that it may be impossible to save him from his own mistakes. the republican presidential candidate fired back on twitter calling the times, quote, a failing newspaper of fiction, but trump's grievance is not just with the "new york times." he seems to hold even a lower view of reporters than he does of his opponent in the election. listen. >> i'll tell you honestly, i'm not running against crooked hillary clinton, i'm running against the crooked media. that's what i'm running against. i'm not running against crooked hillary. >> he talks a lot about the content ft. meade yeah. cnn is no exception. we look at what trump tweets

about his campaign coverage. >> reporter: donald trump's campaign is all about getting attention, media attention. >> look at all those cameras. look at all the red lights. i know i'm here for the ratings, but it's a little bit ridiculous. >> reporter: but trump likes to have it both ways, his favorite show is "meet the press." >> these people are the lowest form of life. >> this sleazy guy right over here from abc, he's a sleaze. >> the washington post. one of the most dishonest papers in the world. >> reporter: when the going gets tough, trump gets tough on the people covering his campaign. right now especially cnn. >> fox has matured but cnn has been catastrophic. it's so dishonest. >> reporter: lately he doesn't seem to want the attention at all. >> they cover things that are -- that should not be covered. >> reporter: hillary clinton does face daily scrutiny, especially about her e-mail server, but clinton usually

keeps her media critiques private. trump tweets his on an hourly basis. cnn, "new york times," washington post, he's objected to a dozen things just this week alone. on friday he called cnn ratings challenged, but odds are he's watching this program right now. watching cable news and then reacting to it is a defining feature of his campaign. >> you ought to see these news organizations yesterday when i said obama, right? did you see that? that obama is the founder of isis. >> reporter: time and time again he says the media is rigged against him. >> the media is rigged. it's rigged. it's crooked as hell. >> reporter: he is far from the first candidate to blame the media. >> here's a little news flash for those reporters and commentators. i'm not going to washington to seek their good opinion. >> reporter: sometimes when campaigns are down in the polls, the anti-press talk gets even louder. the difference with trump is the

intensity. he is not just running against clinton, he is running against us. >> that was cnn money senior media correspondent brian stelter reporting. donald trump has been under fire for refusing to release his income taxes but his running mate, vice presidential candidate mike pence is taking a different approach. mike pence says he will release his own tax returns before election day in november. he promises though that it will be a, quote, quick read. cuba is known for its cigars, but this is no ordinary cigar. it's 90 meet terters long or ju of 3 feet. it was rolled out for fidel castro and his birthday celebration. >> reporter: a frail but very much alive fidel castro made a rare public appearance in a government celebration marking his 90th birthday. castro was seated next to the

current cuban president, raul castro and nicholas maduro. castro needed help rising to his feet as school children sang him "happy birthday." castro was once omni president in cuban life, but he's rarely seen these days. years ago they said cass ttro's greatest achievement was staying alive. but even as cuba normalized its relations with the united states and embraces capitalism, castro has once again proved that he's a survivor. patrick oppmann, cnn, savannah. >> thank you. still ahead here, deadly flooding has engulfed parts of louisiana and heavy rainfall is still drenching parts of that state. details on when people could start to see some relief from the flooding there. plus, police are

investigating a mass stabbing attack on a train in switzerland. what they're saying about the suspect coming up. we are live in atlanta at this hour broadcasting in the united states and around the world. you're watching "cnn newsroom." and grease in just a minute mr. clean will clean your whole house and every room that's in it. floors, doors, walls, halls he's so tough, he cleans'em all grimy tubs and tiles he'll do so your bathroom looks clean as new mr. clean gets tough on stuck-on stuff cleans kitchens in a minute. mr. clean will clean your whole house and every room that's in it. mr. clean, mr. clean, mr. clean! is it a force of nature?

and call your doctor right away. other side effects include gas, stomach-area pain and swelling. talk to your doctor about managing your symptoms proactively with linzess.

>> welcome back to our viewers here in the united states and around the world. you are watching "cnn newsroom." it is good to have you with us. i'm george howell. with the headlines we're following for you this hour. legendary swimmer michael phelps won gold in his final olympic race this saturday. he swam in the 4x100 meter medley. that makes gold medal number 23 for the american. by far the all-time record.

in the u.s. presidential race, donald trump's running mate mike pence says he will release his tax returns. trump is resisting saying his tax returns are being audited. two separate airstrikes by saudi-led coalition forces have killed more than a dozen children in northern yemen. according to yemen's health ministry, the first strike hit a private school killing at least 10 children there, wounding 28 others. in the state of wisconsin milwaukee police say they are restoring order in the streets after a night of violence. crowds gathered saturday night hours after police shot and killed an armed man, i should say, during a foot chase. as officers tried to break up the protests, things then turned violence. they say people set buildings on fire. they say people threw bricks at

police officers. one officer was even hit in the head by a brick thrown through his windshield. earlier we heard from the brother of the suspect killed by police. listen. >> right now you got a city riot going on because once again the police has failed to protect us like they say they was going to do. they failed to be here for the people like they say -- like they sworn in to do, you know? us as a community, we not going to protect ourselves, but we don't have anyone to protect us, then this is what you get. >> that suspect was 23 years old. the officer who shot him has been put on administrative duty while the investigation is underway. moving on now to the state of louisiana, drenching rains have produced disastrous flooding there. at least three people have died. one person is reported missing. the video that you see here is from walker, louisiana where caskets have been seen floating in a cemetery. the state's governor calls the

flooding a truly historic event and he says everyone needs to be in response mode. >> what we know is we have record levels of flooding along rivers and creeks. and because these are record floods, we don't know how wide the water is going to get in those areas. we don't -- this is unprecedented so we don't have records that we can go back and see who all's going to be impacted. >> let's get the very latest on the flooding there. our meteorologist derek van dam has been following this for a long time now. derek, any relief in sight? >> doesn't look like the areas that have been hardest hit in the short term, i should say the next six hours or so. george, we've been showing some dramatic video of rescues taking place in baton rouge area. we have some dramatic video from the coast guard. this is a helicopter making a rescue. the coast guard continues to

rescue people here in distress on rooftops, from their automobiles, trailers due to flooding. again, this is the baton rouge area. in total two helicopter crews from the coast guard and the assistant guard area mobile, you see three individuals in that basket there. compelling video to watch. people, again, seeking higher ground when the water rises so quickly during this flash flooding event. i want to show you. i talked about the areas that have been hardest hit and there's no relief for the next six hours. the reason i say that is there's new flairup moving from the gulf coast inland towards the baton rouge area and the midwest. this is i-95, interstate 10 and this is where the flash flood warnings and watches are continuing. rivers and streams are continuing to subside. this is the radar estimated

rainfall totals. you can see the shading of white there indicating 20 plus inches in a few different locations. we've had official reports up to 27 inches of rain. we continue to tally that on with more rain in sight at least for the foreseeable future. you can see, however, high resolution radar forces to disperse the area. what's interesting to note is that moisture is going to spread northward not in the heavy sense that we've had lately but nonetheless we have flash flood watches from memphis through st. louis and into the ohio river valley. this is something that we are going to continue to monitor as we go forward for the next day or so. >> derek, thank you. >> thanks very much. looking ahead at competition in rio. sunday's biggest event is the men's 100 meter where superstar usain bolt will look to defend

the first of these three sprinting titles. bolt is going after the first ever treble treble. the first of 100, 200, 400 meter sprints. the women will compete in the marathon and the triple triple jump. grenada's track wonder will be competing. corani james won in 2012 when he nabbed gold for that event and now he's looking to do it again. ♪ ♪ >> my name is kirani james and i'm aiming for gold.

just having that, you know, confidence of me from grenada, small island competing against the larger caribbean countries and winning races and doing well, i think that really set in that i could compete and do really, really well in track. we're very proud people, and any time we have something positive that we can be proud of, you know, we go the extra mile to let people know how proud we are of something. so just winning that first medal i think home -- everyone at home erupted. it was a very historic moment and something that i will cherish, you know, every day of my life. i called my mother and, you know, she was out in the streets along with everybody else. she couldn't hear me, i couldn't hear her because there was so

many noise and she -- i guess she just kept handing the phone to various people, random people, either that or they were grabbing the phone from her, i'm not sure. just to hear people's voice and how proud they were and how excited of winning grenada's first olympic gold medal. i think that's when it really hit me that i did something extraordinary for my country. training has been going great. you know, injury free and, you know, i have competed this year. i would say it's been very positive to do well. as long as i do that, then i'm happy. they wanted the games for a reason. the olympic community saw something special. i'm going in with the mind set that it's going to be great

games and when we get there we'll see. so hopefully they get everything sorted out by then and it will be a memorable games. >> it is so exciting to see all of these different stories. we certainly wish him the very best. this is "cnn newsroom." we want to tell you, of course, about the syrian city of manbij. celebrations and a chance to start life again after isis is forced out of that city. why manbij is crucial for the fight against isis. ven nez well lans cross into colombia to buy food. what led the president to change his mind about the border after this. stay with us. absolutely ageless® night cream with active naturals® blackberry complex. younger looking skin can start today. absolutely ageless® from aveeno®. what is freedom?

police in switzerland are investigating a train accident that wounded six passengers saturday. they say a 27-year-old suspect set fire to the train with some sort of liquid and stabbed several passengers on board. the 6-year-old boy is among those injured and the suspect was also hurt in the fire. the attack happened in the east part of that country on a service line that was shut down. authorities say that dozens of people were on board and the train was heavily damaged. people in the key syrian city of manbij now have a sliver of hope that their lives will recover. fighters backed by the united states have forced isis out of that city. the u.s. hoping to acquire key intelligence now left behind by that terror group. washington wants to use manbij as a spring board to retake raqqah, which is the de facto

capitol of isis. our senior international correspondent ben wideman has this story for us. >> reporter: with the fall of manbij, isis has lost another important strong hold in syria, the latest in the string of towns and cities in iraq and syria where isis's black banner has been torn down. inhabitants of this syrian town, it was a relief to be liberated by the u.s.-supported syrian democratic forces, a coalition of kurdish and arab fighters. the inhabitants of the town enjoying relief from isis's draconian regime. some men took the opportunity to shave off their once mandatory beards and men and also women had the opportunity to enjoy a smoke in public for the first time in years without fear of a lashing. some women took the opportunity to burn their head to toe nicab's, the stifling garment

required if they wanted to go out in public. isis has lost an important supply route between the turkish border and its de facto capitol of raqqah, but this is just one battle won. the war against isis is still far from over. isis still controls mosul, the second largest city in iraq, and it still controls large tracts of northern syria. ben wideman, cnn, istanbul. >> ben, thank you. in venezuela, thousands of desperate citizens crossed into colombia on saturday after the two countries agreed to at least temporarily re-open the border there. venezuelans are anxious to buy food and other basic supplies, items they can't find or afford in their country. falling oil prices have contributed to a severe economic recession in that nation. the opposition wants to remove the president, nicholas madura,

neutrogena® rapid wrinkle repair works... ...in one week. with the... fastest retinol formula. ...to visibly reduce wrinkles. neutrogena®. welcome back to "cnn newsroom." i'm george howell. so if you've been watching the rio olympics you may have been watching a trend among the athletes. the dark circles on their bodies. you see it here. these are part of a therapeutic technique known as cupping. earlier john mann spoke with our chief medical correspondent dr. sanjay gupta and they started by discussing exactly what is cupping. here's the answer.

>> well, the name's a pretty good one for this because they're actually taking these cups and you're putting it on the skin and you're creating a certain amount of suction. sometimes the cups are glass, for example, and they heat up the inside and this creates a vacuum on the skin. sometimes they're actual suction cups. the whole idea is to basically pull the skin up. what you're really doing is pulling it away from the muscle that's underneath and allowing those blood vessels that are between the skin and muscle to rupture and bring more blood to the area. that's the goal of cupping. that's why you see the bad bruises on phelps. >> does it work? does it do any good? >> it's one of those things. for a lot of people they believe it works for them. they've been doing it for thousands of years in can you be tris like china. it's withstood that test of time. they believe that it actually promotes healing so people who are actually training really hard, the recovery time can sometimes be inhibiting in terms of them exercising so they want to improve their recovery time and some people say it takes

pain away from some areas over stressed or over worked. it doesn't appear to be harmful, but, again, the idea whether something is effective is very much in the eye of the beholder. it could be placebo effects. they're athletes who are doing it. >> it doesn't sound like there are convincing scientific proof. >> there's no study around it. there's no money to be made on something like this. it's literally something you can do in your own home. a big pharma company is not going to invest in this. studies are small. they're people who are athletes who decide they want to study it by themselves. >> sometimes when people try alternative medicine doctors say, don't do that, because it means you're not going to get the cure that you need. >> yes. >> is anyone with muscle trouble that could be helped by a doctor or by a physiotherapist going to make a mistake if they try that route instead? >> it's a good question. i think for the average person who may be having muscle

problems, you know, you obviously still want to get that checked out to make sure. these are athletes where, you know, obviously very highly trained and thoroughly checked out. they realize that they're healthy people who are looking for some sorts of improvements again in terms of recovery time or quicker relief of pain. they don't take -- it's not a substance. it's something they're doing to their own bodies. it's important that because there's not, you know, these randomized trials around this, you can't assert these sort of things. look at the guy like phelps. i mean, he's been training for years for these few days. would you -- if you give them some credit including the team, look, we're not going to do anything that's going to inhibit his performance, might help, why not? that's their attitude. >> sanjay gupta, thank you very much. >> you've got it, thank you. some sad news to share with you for "star wars" fans. the british actor kenny baker has died. the barely 1 meter or three foot tall baker, he was best known

"exercise more." i know that. "try laxatives..." i know. believe me. it's like i've. tried. everything! my chronic constipation keeps coming back. i know that. tell me something i don't know. (vo) linzess works differently from laxatives. linzess treats adults with ibs with constipation, or chronic constipation. it can help relieve your belly pain, and lets you have more frequent and complete bowel movements that are easier to pass. do not give linzess to children under 6 and it should not be given to children 6 to 17. it may harm them. don't take linzess if you have a bowel blockage. get immediate help if you develop unusual or severe stomach pain, especially with bloody or black stools. the most common side effect is diarrhea, sometimes severe. if it's severe stop taking linzess and call your doctor right away. other side effects include gas, stomach-area pain and swelling. talk to your doctor about managing your symptoms proactively with linzess.
