the immigration crisis in europe. some devastating images out of austria, and 70 migrants found dead in a truck. and the calls grow louder now for europe to do something about it. tropical form erika. ahead, we look at where it's headed next. and life on mars. pictures from a nasa rover on the internet has social media buzzing. i'm george howell, this is china

n welcome to our viewers in the united states and around the world. we start this hour with the migrant crisis in europe. authorities from hungary and italy have made numerous arrests. in the meantime, workers face the grim task of trying to identify the victims. the arrests come as europe struggles to deal with a record number of migrants entering its countries. many of them refugees from war ravaged or impoverished nations like syria. according to the latest numbers from the u.n., nearly 300,000 people have crossed the mediterranean so it far this year, most of them landing in italy or greece. compare that to all of last year when 219,000 people made that dangerous crossing. as a result, deaths at sea are at record levels this year.

more than 2500 people now reported missing or dead. the deaths this week have renewed calls for europe to find ways to resolve this growing humanitarian crisis. >> i'm horrified and heartbroken as refugees and migrants are losing their lives in the mediterranean, europe and beyond. >> the deaths this week also give a sense of just how desperate many of the people are and highlight that the risks that they're willing to take to leave their homelands for a better life in europe. here's a look at the trek that many are taking. it's a dangerous journey that goes north through turkey, then into greece and macedonia, then into serbia and hungary. arwa day man has momon has more. >> reporter: just before dawn, we are on the same waters.

[ speaking in foreign language ] >> reporter: that's a boat that we were filming. help us, help us, the men cry out, as our captain tosses a rope. 60 migrants, crammed together. clutching life vests and inner tubes. on shore, many disappear into waiting taxis. one man says if death wasn't chasing us we would not be trying this. by day, holiday makers enjoy the same beach. for them, the greek island destination is just part of the view. the remnants of the migrants' treacherous journey clutter the shoreline, clothes, shoes. this is just one of the areas around the capital. mohammed arrived a week ago from syria. isis detained us for two days,

he says, they wanted us to confess that we were going to turkey to train to fight against them. after enduring beatings, he says, they were finally released. it is the pain of parents who thought they were saving their children, hardly able to comprehend that this is the europe they risked their lives for. people here are so angry, so upset. they can't believe that this is happening to them. in europe, everyone who we've been speaking to here has been stuck in these conditions for the last four days. macedonian police opened the border for a few at a time. they stumble through, tightly gripping their childrens' arms. some collapse and are carried off. panic swells. young men throw themselves across. other refugees decide to make a run for it. bolting through any opening they

find. darting across the fields. for the refugee, the trek is a pendulum of emotions. from elation at the small moments of respite, to sheer despair. these woods make up part of the unmarked border between serbia and hungary where migrants hide out under cover of darkness to evade capture. exhausted children slump on their parents' shoulders. and others, like this 9-year-old, bravely declare that, no, he's not tired. he's from syria, one of his relatives from the isis capital of raqqah. it's famous, he jokes. a dark humor is allmany have left in the face of all they have endured. >> arwa damon now joins us live in budapest, hungary. i'm struck by a line in your piece. if death wasn't chasing us, we wouldn't be trying this.

i mean, you really get a sense that these are people who are doing their best to seek better lives for their families, struggling to break through anyway they can. what more can you tell us about what you've seen? >> reporter: well, george, for a lot of them, they're really beginning to question that decision, given everything that they have gone through, just to get this far and the fact that the road ahead right now is quite uncertain. this is the scene at the budapest train station, where you have all of these refugees. le many of whom have been waiting for days because they don't know how to navigate the system and move on forward. they are not able to take trains from budapest to germany. we spoke tofamily who has been living in these conditions for five days.

they were asked why they had no passport, and they were removed from the train. this is why. because transport onwards to western europe is not being facilitated. in fact, is being impeded that some are resorting to the use of criminal gangs and smugglers. and it is leading to the unnecessary deaths like the ones we saw between budapest and vienna where 71 people presumably suffocated to death in the back of that truck. people don't understand why hung ary is not facilitating them. germany has said that it will be taking in hundreds of refugees. hundreds of thousands of refugees this year, so they want to get them. they really don't understand why europe is not coming together at this stage and making what is already a phenomenally difficult journey that little bit easier.

>> and arwa, you know, obviously, there is a discussion about europe finding a way to share the influx of people that are coming in. what more can you tell us about where those talks are at this point? >> reporter: well, they're still trying to figure out quotas and certain logistics in terms of actually moving these people along. one would hope that there would be a bit more urgency in all of this, especially to get these people moving on to the countries that are willing to host them. but the other problem when it comes to implementing quotas is that you can't force a person to go live in a country that they don't want to live in. a lot of these people we have been talking to, they have families in places like germany, holland, sweden. they don't want to end up in another place, another country, just because they're having to fulfill a quota. so all of this really needs to be taken into consideration. then of course, george, the bigger picture has to be

address. and this is something that no nation necessarily knows how to address. how do you end war? how do you end the conditions that are forcing people to take this kind of a journey? that is the much bigger challenge in all of this. >> arwa damon live for us in budapest, hungary. thank you so much for your reporting. and as arwa gave you the sense, this is considered the biggest migrant crisis since world war ii, to stop the influx of more people going across the borders, more walls are going up. >> reporter: by boat, by train. on foot, risking lives, ever desperate, fleeing fighting or simply looking for work. migrants are on the move in numbers not seen in generations. >> today the world finds itself

facing the worst refugee crisis since the second world war. >> reporter: more than a 250,000 crossing the ocean so far. no solution. >> europe finds itself struggling, fighting to deal with the high influxes of people seeking refuge within our borders. >> reporter: from turkey to france. borders are being fortified. walls built every country for themselves. no grand plan from european union headquarters and brussels. >> i'm afraid it has been incoherent is the only word you can describe the policy for brussels. there has been no policy. >> reporter: jeffrey robertson, the leading u.k. rights lawyer predicts without a clear european strategy europe is hided for the rocks.

>> we'll see europe move right, move nationalist. we will see britain being the first. and there may be others to leave the european union. >> reporter: the drift to the right is already happening. from sweden to denmark, to britain and france. and greece in the far south. right wing parties are prospering. czech and slovak ministers are feeling tensions saying they will only take christian migrants. the problem is huge. criminal gangs ferrying migrants from libya to italy. the same from turkey to greece. once ashore heading to germany, france and sweden. bottlenecks at borders are becoming the norm. across the channel from england, a migrant camp city in calais. migrants recently getting tear

gassed. european human rights law dictates governments must help migrants. >> which requires them to treat all people within their jurisdiction humanely, with a basic minimum of humanity. >> reporter: 25 years since the berlin wall came down, new barriers are going up now faster than anytime since the cold war began. they leaked back then, and few expect them to work now. >> even if they build to the sky, they may lie in front. they're going to pass because god bring us here. >> reporter: his fate, like those who have come before him and the many who may follow, is up in the air at the whim of some chilly political winds. nic robertson, cnn, london. >> as we mentioned, given this dangerous journey that migrants are taking the number of deaths

at sea is at record level this year. for more on agencies that are trying to help the situation, you can log onto our website right there, cnn.com to get information. we could learn soon what an egyptian judge also decided in the retrial of al jazeera journalist of accused of helping the muslim brotherhood. they were convicted on charges that they spread false news to bring down the egyptian regime. you're looking at live pictures from egypt. they spent a year in prison and were originally sentenced to up to ten years. gresta was deported earlier this year. a woman is making history.

potentially the u.s. coast. let's turn to derek van dam tracking it all. >> seeing the visuals coming out of dominica, it was devastating. the prime minister in a televised address to the nation said that their island had been setback 20 years due to the destruction and damage from the storm. so they're going to be reeling from this for some time, picking up the pieces. >> and millions of dollars. >> and millions of dollars to rebuild what has been lost, unfortunately. take a look at some of the footage. and you can see why this area is so prone to landslides and flooding. those are washed away roadways and bridges. look at the water it funnels down and leads to the 20 fatalities, thanks to the flash flooding that took place there. go to the next video, and you can see some of the stronger waves that were pushed ashore in the dominican republic.

also people just trying to pick up the pieces from the stronger winds they experienced there. wind maker, it still left power lines and trees and some damage to some of the local structures in that particular area. santa domingo in the dominican republic. take a look at the graphics. there have been boats washing ashore in the area and some of the light posts and even the electrical signs just laying in the middle of the roadways, all due to tropical storm erika. here's the latest from the national hurricane center. 75 kilometer per hour winds, just south and east of cuba. this storm is encountering severe upper level winds it's going to help disintegrate the storm into a tropical depression. it's robbed the moisture source, allowing for the storm system to almost break apart. however, it is going to move into warmer waters, and we do

anticipate the storm to potentially strengthen right back into tropical storm category as it moves into the gulf of mexico, and that has the potential to impact -- well, there it is, the florida mainland in the united states, george, so this storm doesn't have the potential to be a major wind maker at this stage, all signs pointing towards them, but it could be a rain soaker for florida, and they've already received a significant amount of rain this month, so it could lead to flooding in the area. more to come. it is another storm that is now infamous. hurricane katrina. it's been one decade since that storm brought mass devastation to the u.s. gulf coast. among the hardest hit areas was the city of new orleans which sits below sea level. levees failed. 1 million people were displaced by this big, monster storm, but it is unclear just how many people were killed. the official number, from several years ago, is close to

2,000, but many believe that number is actually much higher than that. and we will never truly know just how many people were killed in the storm. former u.s. president george w. bush visited the city on friday. his administration has long been criticized for its slow response to the disaster, but this time, mr. bush focussed on the positive days after those dark days. he said that new orleans was a city where the levees gave out, but the people never gave up. there have been so many amazing stories of survival from katrina, and this one is no different. when the storm hit, canisters containing frozen embryos went nine days without power or refrigeration. on the tenth day, volunteer rescue worker saved embryos, and now the twin sons are eigh8 yea.

>> gosh, those seven years that we, man, it was bad. we cried and prayed and i was angry. and i didn't know why. why? you know, they said nothing's wrong. there's no reason why you can't have babies. >> reporter: andrea will and her husband tried everything to get pregnant, but nothing worked. nothing until an in-vitro process gave them twin boys. another set of embryos were still frozen about two hours from their mississippi home. then katrina struck. >> when the hurricane came through, we lost our power, we lost phone. i had no clue what was happening anywhere else except where we were, and it just hit my, oh, my gosh. they're in the same predicament as all these people sitting at the superdome that we're seeing on tv. >> reporter: the canisters containing her embryos were moved to the second floor.

now that building was flooding and without power. but a rescue mission was under way. >> i was a sergeant with the illinois conservation police. illinois put together a task force, and offered up services to louisiana for whatever they were in need of. they told us that we have doctors and a couple nurses that we need to transport out there to get into the flooded hospital, and we need to try and recover these canisters that have frozen embryos in them. the amount of liquid nitrogen that was keeping them frozen is quickly depleting, especially in this heat, and we have to get them to a facility and get them back into that cold storage. whether we got to the hospital and we got to the canisters, and the doctors basically looked at them and said okay, they haven't been breached. they're secure. so we carried them down the stairs, loaded them in in our boats, and it starts to hit you. we didn't just come to pick up

canisters. we came in here and picked up lives. this is 1200 potential children. in our tour of being down there, we'd seen a lot of death. we'd seen a lot of destruction. and now, we've given back, we've given new life, new hope to those families that thought it was deteriorated when katrina hit. >> reporter: the rescue occurred on september 11, 2005. in september of 2006, she had twins, ben and sam, with the embryos brought to full term. >> i just thank the people that rescued our children. i would introduce them to sam and ben, and i would tell them, thank you for believing that these embryos were people. cause i know not everybody believes that. but they are. those are babies. and i would say, look what you did. and my children are alive today because you did that.

and i would hug their neck and i'd probably cry. and i would just, i would just thank them. >> i would just thank them and tell them that they're the heroes. most definitely for doing that. do you have a reaction to that? >> yeah. excuse me. that makes it help, it's amazing to think how much we impacted them. >> reporter: that's sam and ben. >> that is awesome. that is fantastic.

and a warm welcome back to our viewers here in the united states and all around the world. you are watching "cnn newsroom." good to have you with us. i'm george howell. following the deaths of dozens of migrants, authorities in italy have made numerous arrests. many of the people charged with human trafficking and murder. it comes as nations struggle to cope with people coming in from africa. tropical storm erika is dumping heavy rain over haiti and will track to the warm waters off cuba in the coming hours. at least 20 people so far have died from this storm. economy watchers are looking to monday to see what the global

markets will do. fair to say, it has been a wild ride after china's economy triggered worldwide volatility. the worldwide of markets had some of their biggest swings in history before rebounding. a powerful new home video droves home the horror of daily life in syria. this video, the humanitarian group "save the children", brought the reality of living under siege to a town in the united kingdom, and it shows what millions of syrians are facing every day. take a look. >> do you have some identification on you please? >> i'm sorry. >> you think i'm stupid? you're talking rubbish. >> i don't want to lay my hands on you, mate. [ sirens ] >> in the last 24 hours, schools across the country have been forced to shut their towards.

it's too dangerous for children to attend, as armed groups take over and the violence escalates. >> school is closed. >> why is school closed? >> they're closed. all schools in all this area. >> can you explain why? can you give me a phone number of someone to talk to, please, because this is not acceptable. we had no notification. no nothing. >> with major supply lines blocked, food stocks are running dangerously low. >> what you see on the shelves is what we've got. >> children are now going without food on a daily basis. >> i have to be on a list? >> to get bread, milk and eggs. >> oh, my god, i didn't know this was going on. >> what do you mean? >> things just aren't getting through. >> don't be stupid. >> 8 pound 20. >> for a can of brcio?

>> is this going on everywhere? >> and a new crisis is emerging. [ sirens. ] >> i have a patient in the paba. he needs to get to the hospital. >> blockades are preventing thousands from reaching life-saving care. >> medical supplies aren't reaching the most vulnerable. >> why won't you let me through? my baby is sick! >> with children particularly affected. >> the baby's sick. >> someone's life is at risk. >> i don't want to lay my hands on you, mate. ♪

>> it's a powerful, social experiment. we're joined now by caroline anning, the humanitarian media manager for save the children. caroline, thank you for being with us. we see an image right now of a child sitting on rubble. and we've seen these other images part of this video. it's powerful to say the least. what was the reaction when people went through this experience? >> people as reactions were amazing. they were so shocked and appalled. it's not something that you expect in a small town in the uk or in any safe developed country. people don't expect not to be able to send their children to the school, not to go to the shop and not be able to get bread and milk. they were upset. they were angry. a lot of people were very angry this was happening to them. but for them it only lasted for

ten minutes, and then we told them the reality. and people said god, it really made me think. you can't necessarily imagine what's happening to people living under siege in syria. just to experience it for ten minutes was really kind of emotional for people. >> you know, to see the images is one thing, but i mean help our viewers understand, what are these children leaving behind? and what are they facing? >> it's, you know, we're now four and a half years into the war in syria. and many areas have been besieged for years now. so there's 500,000 people living in siege in syria, many in areas where we can't go. and we speak to people in those areas, and it's like hell on earth. there's no food, no clean water, no medical care. people telling us without the hospitals and the doctors gone, they're using anything they can to patch up wounds, to deal with

illnesses. and people are very resilient. we know groups running underground schools and underground hospitals, but it's a desperate situation. that's why we are always calling on the international community to not forget about sire yeyria. think about the human beings still trapped in these situations and aid agencies like us can't get help to them. >> i'm curious about the experience. because for many people around the world, they see these images, but they're so far removed. for people who went through this particular experience, was there some kind of a call to action? did people want to do something? after what they saw and experienced? >> they did. absolutely. yes. the people in the town of surrey who took part wanted to be part of our campaign. we are working inside syria to continue getting help to those people, but also to call on our

leaders and around the world and the u.n. security council, et cetera, to use their power and influence. and i think all of them felt very strongly afterwards that they wanted to be involved. and these were people chosen at random, you know. they just happened to be going into their shop or turning up at their school on that day. but everybody afterwards was, okay, we need to act on this. this can't be happening to children and families and innocent people. >> this is happening to children. that video certainly shares an experience in the images. it's always so powerful. caroline anning, thank you so much for taking time to explain what's happening with that. switching now to the world stock markets, they took a wild ride this week. both europe and u.s. markets closed with mixed numbers on friday with some suffering th biggest swings in history andrew

stevens has the story. >> what a week, an absolute rollrol rollercoaster, ending like this on friday. the shanghai down almost 8%. hong kong closing out the week by 3.5% down. but japan only 1.5% and the australian markets actually finishing higher. it could have been so much worse. it all traces back to august 11, when china's central bank first allowed the yuan to slide in value. that worried the investors the world over with some speculating that this was a way to boost the economy through exports. but thin on friday august 21st. >> a major manufacturing activity hit the lowest level in 77 months. >> to say it rattled the markets would be an understatement. markets across asia trading lower, but it was shanghai the

following week where the real selling took place. >> asian markets suffering huge losses in monday's session. >> europe followed suit with the dex tentering a bear march kit. then it was over to wall street. >> 1,000 points here, incredibly rare to see a move that brisk. >> in the first few minutes, the dow suffered its worst-ever points loss in a single day. the dow still recorded its worst day in four years. back in asia the next day, the selling continued as beijing apparently refused to intervene. the shanghai market at this stage was down more than 15% in two days. and then, late on tuesday, china's central bank moved to calm the markets. it cut interest rates and cut the amount of money banks must hold, and in the thick pumped

billions of dollars into the economy. but there was still little sign of a letup. >> no relief, and no respite after days of stomach-churning losses. >> a choppy day followed on wednesday before finally some semblance of calm emerged on thursday. helped, no doubt, by reports suggesting that beijing was throwing money at the problem, buying stocks once again to boost the market. at markets closed in asia this friday, investors breathed a collective sigh of relief. one of the most turbulent times on the market in recent memory was finally over. remember, though, that if you bought into the shanghai market a year ago, you'd still be sitting on a pretty tidy profit. but even with policymakers in beijing seemingly prepared to do whatever it takes to restore confidence, analysts fear there is still more volatility to come. for now, though, it's time to

enjoy the weekend. andrew stevens, cnn, hong kong. this is cnn breaking news. and the breaking news we're following this hour and cnn, a judge in cairo, egypt has just issued his verdict in the retrial of three al jazeera journalists. he sentenced mohammed fahmy, peter gresta to prison. more news right after this break.

wires and showed no signs of vents to allow fresh air inside. the deaths this week have renewed calls from the united nations for europe to improve its efforts to resolve this growing crisis. this includes dealing with human traffickers who prey on refugees. then look at this. migrants and residents in budapest, hungary, came together on friday to light candles in memory of those who died inside that truck earlier this week. four children including a baby girl were among those found dead in that very tragic incident. c this n arwa damon joins us. good to have you with us. i know you are following part of the trek that many migrants are taking. what more can you tell us about what you have seen? >> it's been very difficult for so many of these refugees.

the vast swrort of them from the war zones of syria and iraq. some as far away as afghanistan. they are not yet finding what it is that they're looking for. this is the scene at the budapest train station where many of them are waiting, trying to figure out how to safely get to their final destination because they can't get on trains here. everyone who we spoke to is attempting to buy a train ticket and has want been allowed to board the train or they've been turned back at the hungarian-austrian borders. that's why many are having to resort to these criminal gangs. who do not have their best interests at heart. it is as we saw in that tragedy that took place in the back of that truck where 71 people suffocated to death, that increasingly is going to be happening unless there is some sort of a solution to get these people safely to the countries that are willing to host them, are willing to take them in like

swre germany. just to get this far is such a difficult and long journey. take a look. >> reporter: a rubber dingy takes on the turkish coast guard. just before dawn we are on the same waters. that's the boat that we were fi filming. help us, help us they call out as our captain toss az roach. 60 migrants are clambering together. on shore most disappear into waiting attacks. one wrung man barely says if death wasn't chasing us, we would not be trying this. by day holiday makers enswroi the same beach. for them the greek island destination is just part of the view. the remnants of the migrants

litter the shoreline. shoes, clothing, a discarded dingy. this is just one of the many launch points that surround the capital. mohammed arrived a week ago from syria. isis detained us for two days, he says. they wanted us to confess that we were coming to turkey to be trained to fight against them. after enduring beatings, he says, he was finally released. it is the pain of parents who thought they were saving their children hardly able to comprehend that this is the europe they risked their lives for. >> people here are so angry, so upset. they can't believe that this is happening to them in europe. everyone who we've been speaking to here has been stuck in these conditions for the last four days. >> macedonian police opened the border for a few at a time. they stumble through, tightly

gripping their children's arms. some collapse and are carried off. panic swells. wrung men throw themselves across. other refugees decide to make a run for it bolting through any opening they find, darting across the fields. for the refugees the trek is a pendulum of emotions from elation at the small moments of respite to sheer despair. these woods make a part of the unmarked border between certain wra and hungary where migrants hide out under cover of darkness to evade capture. exhausted children slump on their parents' shoulders. others, like this one declare that, no, he is not tired. he is from syria. one of his relatives from the isis capital. it's famous, he jokes. a dark humor is all many have left in the face of all they

have endured. >> george, it's especially bitter for so many of them to have come this far, to have reached the gateway to their dreams and still be left in conditions like this. they're not used to living on the streets. they haven't bathed for days. many of them are struggling to get food and water, and especially medicine for the babies. that is very difficult for them to find as well. >> very dangerous journey. even when they get to a place like budapest, hungary, still very difficult. hard to manage situation for them. arwa damon, thank you for your reporting, and we'll continue to stay in touch with you. the number of migrants continues to reach record levels this year. the latest numbers from the u.n. show more than 300,000 have crossed the mediterranean. most of them landing in its or greece. during all of last year 219,000 people made that dangerous

crossing. as a result, the number of deaths at sea is also at record levels this year with more than 2,500 now reported either missing or dead. many of those are fleeing conflict areas like the war in syria. earlier i spoke with caroline, a humanitarian media manager for save the children spshgs she spoke of the shallenings that workers face trying to help those in the conflict zone. >> there's half a million people living in this area still. many more in hard to reach wrarz where aid agencies like ours can't go. we speak to people living in those areas, and it's hell on earth. wills no food. there's no clean water. there's no medical care. people are telling us that with all the hospitals there and doctors gone, they're using anything they can to patch up to deal with illnesses, and people are very resilient. they're working with roots that are running wrurnd ground schools and hospitals.

it's a desperate situation. that's why we are always on the international community to not forget about syria and want just think about what's happening with isis, with other groups. think about the fact the human beings who are trapped still in these hor ehor endous situation. sfroo already some uplifting stories coming out of the migrant crisis. with a boost from social media these father and daughter became the syrian refugee -- a man from oslo, norway, posted this photo last week showing this man selling pens on the street of beirut as he cradled his sleeping daughter. the photo struck a cord with many. more than 6,000. it appears he is doing the best he can to support his daughter. within hours with poured in from around the world to help this man. crowd funding page was created, approximate more than $80,000 was raised to help him and his family. and if you would like to help to learn more about the migrant

crisis in europe, you can go to impact your world. it's our website at cnn.com/impact. you can find ways to help refugee that is are fleeing their country for better lives. three al jazeera journalists have just been sentenced for three years in prison in egypt. a judge issued his verdict within the past hour, and the retrial of mohammed, peter, and pierre mohammed, they were previously convicted of aiding a 2013 muslim brotherhood coup. all three say her innocent, and mohammed were in a courtroom today. the muslim brotherhood was declared a terrorist group after the army overthrew president mohammed morsi. thousands of people are

already filling the streets. up to 40,000 are expected to march through sunday. all are demanding that the prime minister step down. people are outraged after a report revealed his private bank accounts held millions of dollars many funds allegedly siphoned from a debt-leyden state fund. the prime minister says he did not take money for his own gain. >> we are keeping a close eye on tropical storm erika. on friday huge waves with the coast of the dominican republic, violent winds tore down trees and floeded the streets. wrerl the storm left a path of destruction. at least 20 people were killed there. florida governor rick scott has declared a state of emergency as

erika moves in. miami residents aren't taking any chances. you see them lining up by the dozens for gas on friday. our meteorologist derek van dam is here. >> it's actually moving over the open waters between cuba and hate where i at the moment, but it has encountered a lot of topography and it's basically just tore down the real strength of the storm. it continues to slowly weaken. i just got an wrupt with the latest stats coming out of that area, and it's even a weaker tropical storm as we speak. take a look at some of the footage coming out of the dominican republic. waves crashing on the shoreline there. people just left to pick up pieces after the wind damage, power liens and trees down on the streets, and i get into my graphics, and can you see there was even a few of the fishing vessels spread on the shore lien there washing up. unfortunate for the men or women who own those particular boats.

here's the latest. the 5:00 a.m. update from the national hurricane center. you can see just how disorganized it is. it moved over hispaniola. not a lot of convection around the center of this. in fact, of the hurricane hunter and reconnaissance aircraft having a hard time deterring where the center of the storm is. you can see just how mountainous hate where i and dominican republic is. again, just robbing the energy source from this particular tropical storm. nonetheless, the models are really all over the place with this particular storm, and they have been for quite some time. we now start to see a general westward shift away from the west coast of florida. going out the next 48 to 72 hours, this storm will move over the gulf of mexico first running parallel with cuba. again, more land mass. robbing it of its energy source. then it opens up boo the long waters of the gulf of mexico.

it could possibly intensify back into a tropical storm. really the concerns going forward as we head into sunday and monday for florida and the u.s. mainland will be the possibility of heavy rain that could lead to localized flooding. again, florida has experienced a significant amount of rain. lately george, over the tampa bay region, they received more rain on top of that is correct the possibility of flooding certainly -- >> i was just looking here. as people prepare in florida, it's important to point out it's looking leak the storm will ob the back side of the state. >> that's right. >> what we saw, you know, people took the storm for granted perhaps, and, you know, maybe didn't heed the warnings, and it caused all kinds of problems with flooding, and a similar thing could develop if we don't take the necessary precautions to get ready for what the storm could actually do. >> thank you so much. do stay in touch as the storm moves forward. breaking news now out of thailand. police in bangkok have arrested

a man that they believed be the main suspect in connection with the bombing there earlier this month. let's go straight to simon live in bangkok for more details. what do you know at this point? >> reporter: george, this is breaking news this hour. police have confirmed to cnn that they have arrested a man believed to be the main suspect in connection with that bombing. what they're telling us, this is the spokesman, george, telling cnn that the suspect is a turkish national, and he was arrested at his apartment which is on the wrout skirts of bangkok around an hour, hour and a half out of town from where the shrine is. it's outside of the main city in the suburbs, and they strongly believe -- police are telling thaws he is the guy they've been

looking for. now, they also have said that they have got teams inside his home looking through, and they believe that they have found the same type of ball bearings inside this man's apartment that they stay at the scene of the bombing. you remember a child was swrurd, and that scene of the bombing too ball bearings were found. the shrine itself, the center, the -- of the shrine, the hindu garden there also had discovering of ball bearings. that was a significant trait of this bombing. it was horrendous and was right in the rush hour 7:00 p.m. local time of people walking to and from work, heading to the shrine. half the harj train stations were there when the bomb went

off. >> while walking to and from work, and also tourists that were in that vicinity when the bomb went off. cnn simon reporting live for us by phone, again, telling us the person arrested is a turkish national, arrested at his apartment outside the main city. simon, we'll stay in touch with you as you learn more details about that. thank you. you're watching cnn newsroom. it has been ten years since hurricane katrina devastated the u.s. gulf coast, and coming up we take a look back at what hospital halves filled with patients when it was swamped by that storm. can a business have a mind? a subconscious. a knack for predicting the future. reflexes faster than the speed of thought. can a business have a spirit? can a business have a soul? can a business be...alive?

britta olsen is my patient. i spend long hours with her checking her heart rate, administering her medication, and just making her comfortable. one night britta told me about a tradition in denmark, "when a person dies," she said, "someone must open the window so the soul can depart." i smiled and squeezed her hand.

it has been one decade sinksz hurricane katrina brought catastrophic devastation to the u.s. gulf coast. nearly 2,000 people were killed and many believe that number would be even much higher than that. millions were displaced. among the hardest hit area was the city of new orleans that sits below sea level. the levies that were supposed to protect that city failed. president george w. bush visited the city on friday. he said new orleans was a place where the levees gave out and its people never gave up. >> the historic hospital now was damaged in new orleans, and the scene of life after death and drama that played out you have it right there.

hopes were high at the place called charity. without a doubt i have seen miracles occur in that building. charity was the ultimate safety net. the hospital of last resort. it was built to serve the poor and uninsured in new orleans, and it never ever shut its doors. not since it opened nearly 300 years ago until katrina. the doctors we are all about to meet were there that day. still, at first it seemed the place where miracles happen had survived. >> a little bit of a sigh of relief. >> i'll tell you how much of a sigh of relief. we all got out. we walked the hospital grounds, walked over to the super dome, walked over to the hyatt hotel and said, okay, we have this. >> but then -- >> the levee that was holding

back the water for lake pontchartrain failed. it's dumping water into the downtown and french quarter areas. >> the water started rising. >> i went through those doors, and what i saw after that was something i'll never forget. >> no food, no power, no way out. for days this charity hospital was forgotten. not a miracle in sight. ♪ we need you you need me we're all part of -- ♪ >> unable to wait any more, the team at charity hospital planned

a daring rescue mission. first paddling critically ill patients across flooded roads and then carrying them up seven flights of stairs to the top of this parking deck. >> we are trying to get them some help. >> what's going to happen if we don't get them out of here? >> two of them have already died here on this ramp waiting to get out in this very spot. they watched as all the patients of another hospital evacuated from the parking deck as the

charity patients, some critically ill, continue to wait. >> that's where the witness of the private company fell short. they clearly saw all these patients. they boated them over. they should have flown all those patients out too, and they chose not to. i don't know why. we have seen a lot of footage of how some of the people died there, and they could have been in a helicopter and flown somewhere. >> preventible deaths. >> absolutely. in my opinion. >> help did eventually come. choppers from the military. these air boats as well that took patients one at a time. nearly a week after hurricane katrina first hit, the last patient was finally evacuated. there's still one more fatality expected. charity hospital itself. >> one of the biggest controversy to emerge after hurricane katrina is what would happen to this building over here. charity hospital. would it reopen, or would the

doors remain closed? this is charity today. overgrown with weeds and disrepair, damaged, broken. hundreds of thousands of people patients no longer had the safety net. katrina had killed the place where miracles happen. mroo i mean, we had to recreate our lives just to deliver health care and deliver health care parking lots afterwards, delivering health care tents, u.s. naval ship comfort to deliver health care and then to move that to an apartment store all within tents for years afterwards, so that's not normal nor is it, you know -- that's kind of third world medicine in a first world country. >> it took ten years, but there's finally some relief. a brand new billion dollar mega hospital with 60 beds set aside

for the mentally ill. the university medical center seems a lifetime away from charity. no longer a refuge for the poor and uninsured. sparkling clean, they can with technology, and reinforced we understand wroez and steal to with stand a future katrina. you won't find the name charity anymore around here. that is gone forever. just a plaque, a reminder of what once was, but they are hoping this is still a place where miracles happen. >> again, that was cnn chief medical correspondent dr. sanjay gupta reporting. we look at how some survivors are still struggling. see more in a cnn special report "katrina, the storm that never stopped" at 8:00 p.m. london or 7:00 p.m. eastern time in the u.s. only here on cnn.

in the state of texas a manhunt is underway for the person who shot and killed a deputy execution-style. the harris county sheriff's office says the suspect ambushed the deputy friday. while the officer was pumping gas. the gunman shot the deputy from behind and kept firing when the officer fell to the ground. authorities identified the deputy as darren, a ten-year veteran of the department and a married father of two. investigators say the gunman drove off in this red truck after the shooting. there is no clear motive at this point. if you have information about that fruk, call authorities. local money watchers are blaming china for this week's volatility in the markets. when we come back, what led to the wild swings. plus, billionaire donald trump said he will fund his presidential campaign himself, so why did he charge people to see him on friday? we look into it as this

shrine bombing. 20 people were killed, and more than 120 wounded when a bomb went off. they arrested a turkish national at his apartment in a city suburb. three al jazeera journalist advisory just been sentenced to three years in prison in egypt. the judge issued a verdict today in their retrial. men were convicted of helping the muslim brotherhood take down the regime. al jazeera says the verdict defies logic. journalists insist that they are innocent. one of turkey's newest ministers is making history. he had he is the first female minister to wear a hijab. it's traditional attire for muslim women. the ban was lifted in 2013. the world stock market are closed until monday when investigators will undoubtedly hope for a smoother trading week. the u.s. and europe closed mixed on friday after the major

american indexes suffered some of the biggest swings in their histories. the dow started with the 1,000 point plunge before rebounding. the global uncertainty is blamed on china's economy. cnn az wra pacific editor andrew stevens explains. >> what a week. an absolute roller coaster. ending on friday with this. not too bad in the end. the shank high composite not surprisingly down almost 8%. hong kong lowsing out the week by 3.5% down. swrapan only 1. 5%, and the australian market finishing higher. it could have been so much worse. it all traces back to august 11th when china's central bank first allowed the uan to slide in value. that worried investigators the world over with some speculating that this was a move to boost the economy through exports, but then on friday, august 21st --

>> that fell to its lowest level in 77 months. >> to say it -- markets across asia trading lower. then it was shank high the following week where the real selling took place. >> asian markets suffering huge losses in monday's session. >> europe followed suit with the dax entering a bear market as panic selling intensified, and then it's over to wall street. >> now we're down 6%. 1,000 points here. incredibly rare to see a move that brisk. >> in the first few minutes the dow suffered its worst ever points loss in a single day. it did gets slightly better, but the dow recorded its worst day in four years. back in asia the next day the selling continues. beijing apparently refused to intervene. the shank high at this stage was

down more than 15% in two days. >> no relief and no respite. stomach-churning losses. >> a choppy day on wednesday before finally some semblance emerged on thursday. no doubt suggesting that beijing was throwing money at the problem. buying stocks once again to boost the markets. as the markets closed in asia this friday, investors breathe a collective sigh of relief. one of the most turbulent times on the market in recent memory was finally over. if you bought into the shanghai market, it still is a city on a

pretty tidy profit. even with policymakers in beijing seemingly prepared to do whatever it takes for restore confidence there is still more volatility to come. for now it's time to enjoy the weekend. we turn our attention now. front runner donald trump held a big event on friday in massachusetts charging $100 per person to attend. billionaire has said that he would fund his own campaign himself, but a sign outside the event directed donors on how to donate money. sarah murray has more.

>> right now you don't. you don't. >> well, as trump helps his allies raise money from secret donors. donors were pressed for thousands of tlarz. one held at the home of ivanka trump's in-laws. the money going not only to a super pact but also a second group. one that can collect unlimited donations without ever naming its donors.

>> i would even take big contribute orz as long as they don't expect anything. while the host is calling it a fundraiser, the candidate is saying it's no such thing. >> i have done some meetings. stroo and downplayed his donation. >> we have a small group of people, i guess it's over here where people can send in -- one woman sent in $7.30 and wrote a beautiful letter and people sending in $10 and $20. i like that that kind it's not a lot of money ultimately.

>> meanwhile democratic presidential candidate hillary clinton took a shot at trump and his hair at democratic party meeting in minneapolis, minnesota. if anyone wonder if mine is real, here's the answer. the hair is real. the lore isn't. color isn't. and come to think of it, i wonder if that's true for donald too. at an event on thursday -- it's not a toupee.

you are watching rnn newsroom. simulating all on the european peninsula as spectacular war games are wrapped tip north korean border. we examine military might inside the isolated nation.

hundreds gathered in seoul, south korea, friday. they mark the 500 days since the sinking of a ferry that killed more than 300 people. many of the victims' families attended the memorial. more than 200 of those killed in the april 2014 disaster. they were teenagers on a school trip. wrerl this year south korean

appeals court found the captain of the ferry guilty of homicide and sentenced him to life in prison. there was a huge show of force in south korea and now we're learning there was an apparent new purge in north korea. u.s. and south korean officials conducted live fire military drills simulating all north korea. kim jong un pushed out of some of his top -- not much is known about the north's military might. ♪ >> north korea loves to threaten all out war. times of high tension, the regime makes that threat multiple times a week. could they do it? do they have the firepower to back those fiery threats? what does the military and the hermit kingdom look like?

>> botts on the ground. they have 7.7 million active snlz in the reserve army. that is nine million soldiers. it is a massive army. the conventional weapons they've been using, though, are old. artillery forces. north korea has 8,600 artillery canons. that is a lot of them. the reason why is that they are cheap. the weapons, though, do have limited range. tanks. 4,300 of them. now, north korean tanks date back to the soviet era. also fighter jets. 820 of them. these fighter jets are extremely old. they're equivalent to the u.s.'s vietnam ear wra fighter jets. one u.s. f-16 could take down a large number of north korean fighters at once. submarines. north korea has approximately 70 of them. they are very old as well. here is where they are effective. they could transport special

forces into south korea which gets us to special forces. north korea has approximately 200,000 soldiers in the special forces. now, troops are cheap, but these troops are highly effective. they are very dangerous. they can travel in small squads so they're hard to detect, and they could carry in chemical weapons. now, to the west chemical weapons are most worrisome. they are difficult to detect, difficult to track. north korea has an unknown number of chemical weapons. one small chemical weapon released here in the heart of soul could do untold damage on the population. missiles. the ones you see at north korea's parades, that massive one they like to show thought to be able to reach the western coast of the united states. the precision is not known or how much warhead payload it could carry. also unknown, how many north korea possesses. so now we can talk about the big

concern. nuclear weapons. north korea tests nuclear weapons in 2006, 2009, and 2013. north korea has an unknown number of nuclear weapons and it is developing its capability in miniatureizing nuclear weapons. that technology will be devastating. it would allow the regime to put nukes on a missile. cyber warfare. north korea has been successful in developing cyber warriors. an estimated 6,000 cyber warfare troops. remember the sony hack? that hack was pinned on north korea's cyber warriors. could they do it? a conventional war would be limited. we have some capability in launching a targeted chemical war, and each day we do get a little lowers to being a global nuclear let. here's the catch. north korea is broke. security experts wildly believe

that without outside help from another rogue country, north korea only has the money to wage war for a few days, but even a war of a few short days would be blued bloody, resulting in mass casualties on the korean peninsula. >> reporting there. you are watching cnn newsroom. it is a lash of science and sacred land. the battle over a giant telescope on a hawaiian voluntarily contain wroe. sweet. for the adult and kid in all of us. ♪ kellogg's frosted mini-wheats® feed your inner kidult ...you want to eat, who wants to (woman) you weat... eat...

six scientists will be spending the next year in hawaii, but they will not ob a beach. they're inside a dome simulating life on mars. the habitat is on the slope of a volcano that has mars-like features. the crew will be monitored using cameras, body movement trackers, and other mechanisms. the goal of the mission is to better understand the risks of a long-term stay on the red planet, and on a nearby volcano a group of astronomers wants to build the world's most sophisticated telescope, but natives are saying not so fast. they believe the sacred mountain has been desecrated enough. rachel crane has the story.

>> i spent a few years trying to stop the desecration of the most beautiful thing in the world. >> this is one of the tallest sumilities in the world. it's also home to 13 of the best astronomical telescopes in science. astronomers believe this is the perfect location to look at the stars. this is the darkest spot on earth. >> incredible. it gives us nice dark skies and allows us to look at fainter and fainter things. >> now, scientists plan to build a new 30 year telescope. the tnt would be the host powerful and advanced telescope on the planet. researchers say the 18 story telescope would let them see up to 13 billion light wreerz away. >> it represents a jump of a factory ten that we'll be able to look ten times further into

our wrun verse. but to native hawaiians health insurance the most sacred mountain on the island. auto grandpas and grandmas. >> it's where their an southeasts os hated it, and they consider it a temple. had he do not want any more construction here and have taken legal action to stop it. a group of opponents that also call themselves protectors sued the state of hawaii for granting the tnt company a permit they say is inconsistent with the state's conservation laws. >> you have to remember that moment in its entirety as a conservation district and conservation districts are one of the highest protected levels and it's supposed to be no construction. >> the debate between astronomers and native hawaiians dates back to the 1960s when the university of hawaii first started plans to turn this into a leading site for astronomy. >> we as hawaiians because

astronomy is so much a part of our life and who we are and what we were, that, in fact, it's kind of crazy not to welcome it. tloo because of the wears, it took several wreerz for the $1.4 billion tnt project to get approved by the state of hawaii. in april they finally started construction. that all came to a halt just a few days later when hubs of protesters showed up and shut down the project. more than 30 protesters were arrested that day on charges of obstruction. there have been several more arrests in the summit because each time tnt workers try to build, protesters step in. >> we have -- science has to accept that there are human limits also. >> the hawaii supreme court has decided to take on the protector's lawsuit. there the final decision will be made on whether the permit to build this telescope is valid or not. in the meantime, the tnt company

has the legal right to continue construction at any point, but the protectors say they're ready to stop them. >> this can't happen. we remain dedicated to protect our mountain. >> the love for our mountain. >> now to a story about a breakthrough on the mystery of black holes. when stars die out, some black holes basically exist, but scientists believe that anything if sucked into a black hole, that it is destroyed. now astro physicist steven hawking has a new they're where i. he says black holes ain't as black as they're painted and that some information may be able to escape. he also says black holes might lead to other universes, but if you pass through a black hole, you couldn't get back to our universe. fascinating. thank you for watching this hour. i'm george howell. for our viewers in the united states, new day is next and for
