we begin with a blistering and dangerous heat wave and a stranglehold across the western united states. millions of people are sweltering this weekend. more than 40 million are under heat alerts as temperatures soar 15 to 20 degrees above normal. for the fifth day in a wroe, electric companies in california are asking customers to turn off unnecessary lights and appliances in order to save electricity during the late afternoon and evening hours. cnn's chris winn reports from los angeles. >> reporter: across the west, the scorching heat is showing no signs of cooling off this holiday weekend. >> our ac at home can only do so much when we're in these triple digits. >> reporter: in glendale, california, residents are seeking refuge at the galleria

shopping mall, taking advantage of the free air conditioning. >> getting out to the mall and just getting out of the house to get some sort of cool release is nice. >> reporter: california is in the midst of its longest heat wave of the year. a major concern, especially in large cities like los angeles, where dark pavement and buildings can easily absorb heat, bringing little relief overnight. skid row is an urban heat island, which is why water is crucial. especially when temperatures hit triple digits. >> free water! agua! >> reporter: that's why volunteers with water drop l.a. are checking up on the unhoused and the elderly. >> did y'all want water? >> yeah, sure. >> reporter: handing out cold water to those who need it. >> at the core, we're all people. we should care about each other. we should love each other. we should look out for each other. >> reporter: the extreme heat wave also testing california's power grid. in irwindale, southern california edison crews are moving transformers and extra equipment throughout the region. >> all hands on deck ready to

respond if there are outages so we can get the power restored as quickly and safely as possible. >> reporter: many californians bracing for more misery ahead. >> it's unsane. it's unbearable to even be home. >> reporter: much of california seeing triple digits this weekend. state officials once again i issuing a flex alert, asking residents to conserve power between 4:00 and 9:00 p.m., all with the hope of easing stress on the power grid. chris nguyen, cnn, los angeles. wildfires in northern california have burned through more than 9,000 acres. in the town of weed, the mill fire has consumed more than 4,000 acres and it's only 25% contained. the nearby mountain fire is currently burning almost 5,000 acres, 5% contained. streets have been littered with the charred remains of cars or cinderblocks where houses stood. fire strike teams are ready

across the state to respond when necessary. cnn's meteorologist derek van dam, as we're seeing that heat is helping to fuel new wildfires. what can you tell us? >> first of all, that imagery you saw there just a moment ago, incredible to see. it really is a product of the heat that is baking the western u.s. right now you're looking at visible satellite imagery. through the daylight yesterday, some of the smoke from the mill fire erupting into the upper levels of the atmosphere, degrading the quality of the air, northern california and neighboring states, as smoke from the wildfires drifts north and northeast. here's the latest. 5% containment with that mountain fire. the mill fire at 25% containment. they have had some progress on combating that fire, but still not enough. that fire continues to expand. we have a red flag warning in place for many locations across central oregon, northern california, parts of colorado, idaho, as well as montana. that continues with our chance of fire today. we have elevated fire conditions

with very dry air and the gusty winds and the extreme heat continuing. speaking of heat, still another 150 or so record high temperatures from today through the middle of the workweek. look at this, utah into salt lake city, this is incredible. they set a daily record yesterday. the day before that, the temperature, the highest september temperature ever recorded at salt lake city. broke that again yesterday alone. incredible, persistent heat that lasts for days and making it very difficult for people who live here. death valley, not a lot of people call this home but we use this as the litmus test on how hot it has been. we've only seen temps over 120 fahrenheit in september about 10 times, dating back to records back to 1911. we've had six times where temperatures have risen above 120 just since 2017. so it really shows you the climate change footprint and angle to this story as well. 40 million americans or more

still impacted by heat alerts. that includes los angeles. triple-digit heat for many the locations just away from the coastline. look at bakersfield, 110 degrees. this heat wave is going to peak at the worst possible moment when everybody wants to be outside celebrating labor day. remember, this is an extended holiday weekend. now the heat builds as we look toward the upper midwest. billings, montana. boise, idaho. triple-digit heat for you as well. >> thanks so much, cnn meteorologist derek van dam, appreciate it. it ultimately wasn't wither that scrapped the artemis 1 launch saturday, it was another hydrogen leak. a new launch date could be weeks away or longer. cnn krista fisher looks at what went wrong. >> reporter: a second scrub, a second hydrogen leak. this leak much bigger than what nasa encountered monday. they can either fix it on the launch pad or they can roll the entire rocket all the way back

to the vav, the vehicle assembly building. but to do that would take about 3 1/2 days. it eats up a ton of time. but regardless of where they make the repairs, as of now, nasa is going to need to roll the rocket back to the vav regardless, because they are in the middle or about to be in the middle of a safety violation with the range. the range is run by the space force. and so nasa says they're going to try to ask the space force for a waiver or an extension, but they just don't know if the space force is going to grant it. so those are the two issues. what that means in terms of when nasa can try again is, they're not going to make this launch window which ends on tuesday. so that means the next launch attempt for the artemis ran rocket is going to be the end of september at the earliest, but more likely sometime in mid to late october if not later. here is nasa's associate

administrator jim fries. >> we don't go into these tests lightly. we don't say, we think, we hope this is going to work. the confidence to do another launch attempt today was born out of the fact that we understood the hydrogen leaks that we had on monday, those are different than the leak that we had today. in terms of scale. one was in the same place, but today was a different signature. we understood the engine issue. so we would confident coming into today. but as the administrator said, we're not going to launch till we're ready. >> reporter: nasa administrator bill nelson was also at that press conference, and he pointed out that the cost of two scrubs is less than the cost of one failure. to be very clear, nasa is very disappointed about this, but they're also acutely aware that this could have been much worse. this is not the worst-case scenario. that would have been an explosion on the launch pad or

shortly after liftoff. so while this is a disappointment and a delay, nasa is confident that at some point, its artemis ran rocket, more than a decade in the making, is finally going to get off this launch pad. the question is when. kristin fisher, cnn, kennedy space center. a dangerous moment in the skies over tupelo, mississippi, on saturday. tupelo police have arrested an airport worker they say stole a plane and threatened to crash it. residents recorded these images showing a twin engine plane, highlighted there, flying low over homes and farms. the man at the controls reportedly called 911 and threatened to crash the plane into a local walmart. both the store and the immediate area were evacuated. you can see the erratic and unpredictable flight path as the pilot kept the plane in the air for hours. police kept talking with the suspect throughout. listen to this. >> negotiators from tupelo

police department made contact with the pilot and were able to convince him to not carry out this deed. we have since learn he landed near the gravestown fire department on highway 4 west in between ashland and ripley. the pilot is in custody currently. >> the suspect is being held on charges of making terroristist threats and grand larceny. police say he worked at the airport for ten years and doesn't appear to be a licensed pilot. it's not clear why the suspect threatened walmart. anger, fear, exhausted resignation are some of the emotions felt by people in jackson, mississippi, this weekend. the city is dealing with a crippling water crisis made worse by historic flooding. bud good news might be on the way for some jackson residents. >> reporter: this is day six of the water crisis here in jackson, mississippi. we just received an update from city officials that the water

treatment plant has made significant gains overnight into this morning, saying the water pressure is now up, so much so that most people in jackson should have water pressure. that's a big change from what happened here just yesterday and what we saw earlier in this week. but the problem still remains that this is an old water treatment plant that has many issues, and so city officials like the mayor warning that there could be more interruptions, more fluctuations to come, that this isn't a permanent fix to this problem. and even if you do have water pressure in your home, that water is still not potable. officials say it is unsafe to drink. the boil water advisory is in effect. that's why the state has set up seven water distribution sites for people in this city to come and pick up free water bottles. but not everyone has access to transportation or can physically lift those bottles and bring them into their homes. we visited a senior facility where one resident told us that

she was so grateful when the mississippi urban league showed up with water bottles for her and her neighbors, take a listen. >> it has been frustrating and just drives you nuts. what's going to happen next? don't know how it going to happen, when it going to happen, anything. it's scary. it really is, it's really scary. not knowing how you're going to make it from one day to another. >> reporter: that boil water advisory continues, and residents still don't know when they will have safe drinking water that they can use in their homes to cook with and to brush their teeth with. we are now told from city officials that water restoration groups from georgia and florida are coming to the state to help. we know that fema has visited. the administrator from fema was on the ground just yesterday and says that those federal dollars will help the city of jackson repair issues in the short-term. but that long-term fix, there's

still no timeline for how long it will take for the water quality to improve. artillery fire hits again near ukraine's largest nuclear plant. emergency procedures kick in just as international inspectors do their work inside. that story ahead. plus the uk's conservative party has voted for its next leader. the winner will be the country's next prime. a live report from london ahead. my active psoriatic arthritis can slow me down. now, skyrizi helps me get going by treating my skin and joints. along with significantly clearer skin,

♪ ukraine's largest nuclear plant has lost its main connection to the power grid again despite the presence of international inspectors. ukrainian officials say artillery fire hit a working power line of the zaporizhzhia power plant saturday. ukraine says one of the two operating nuclear reactors was shut down, emergency procedures were activated, but the other reactor is still delivering a limited amount of electricity into the grid through a backup line. kyiv and moscow have blamed each other for shelling at the plant. the u.n. nuclear watchdog inspectors are also at the site. power delivers water into the plant to cool the reactors and

prevent them from melting down. t . ukraine says one was wounded after a russian rocket strils in the east. this was the scene saturday, a day after russian rockets hit a local market. the attack destroyed nine vehicles. ukraine says it's pushing ahead with its offensive in the sounth which was announced earlier this week. military officials say they've been striking russian command centers, supply lines, and pontoon crossings. there are indications ukrainian troops have made modest gains on the ground despite russian counterattacks. president zelenskyy says moscow is trying to turn up the pressure on europe while attacking ukraine. >> translator: russia wants to destroy the normal life of every european, all countries of our continent. it aims to weaken and intimidate all of europe, every state. what russia cannot achieve by force of arms it seeks to go do

through energy weapons. it is trying to hit europe with poverty and political chaos where it cannot yet use rockets. >> ukrainian prosecutors have identified a russian war crime suspect thanks in part to reporting you saw here on cnn. back in may we showed you video of russian troops gunning down two civilians in the outskirts of kyiv. now prosecutors have announced the name of one suspect, saying cnn reporting played a key role in their investigation. sara sidner has the story. we want to warn you, some of the images in this report are graphic. >> reporter: ukrainian prosecutors say this is the moment an undeniable war crime was carried out by russian soldiers. this video clip obtained by cnn has yet to be seen by the public. it shows russian soldiers firing at something alongside a business they have just overtaken on the outskirts of kyiv. turns out their target is two unsuspecting and unarmed ukrainian civilians who they shoot in the back.

we first reported on this portion of the video in may, showing the business owner dying where he falls. and the guard initially surviving, but bleeding to death after making it back to his guard shack. both men had just spent the last few minutes speaking calmly with the russian soldiers, who appeared to let them go. but we now see two of the soldiers return and fire on them. >> translator: my father's name is leonid. >> reporter: the guard's daughter told us shouldn't the world to know her father's name and what the russians did to him. have you seen the video? >> translator: i can't watch it now. i will save it to the cloud and leave it for my grandchildren and children. they should know about this crime and always ebbwho our neighbors are. >> reporter: now the bucha prosecutor's office says with the help of cnn's story, it has finally identified one of his

executioners. the suspect's name, nikolai sergivich serkovok. ukraine notified russia that their investigation has zeroed in on him as the perpetrator of the cold-blooded killing. while prosecutors don't say how they identified this particular man, but some of their techniques show recognition technology. the ministry of digital transformation gets an image, loads it into their program, and it scrubs social media looking for a match. once they have a match of a soldier -- dead or alive -- they try to corroborate it with friends and family on the soldier's social media sites. >> translator: we have identified about 300 cases. >> reporter: the identification of the latest suspect for war crimes was months in the making. but it is at least one step towards justice for the families

who have had something taken from them they can never get back -- the life of someone they loved. sara sidner, cnn, new york. russia's defense ministry hasn't responded to cnn's request for comment, either to sara sidner's story or our reporting back in may. mikhail gorbachev, the last president of the soviet union, was laid to rest saturday. gorbachev died tuesday at the age of 91 after a long illness. in the 1980s he played a crucial role in bringing the cold war to a peaceful end. gorbachev was buried in a historic moscow cemetery next to his wife, raisa. a farewell ceremony was open to the public. while vladimir putin skipped the services, hundreds of russians didn't. they stood in line for hours to pay final respects. voting is over and the winner will be announced monday in the race to become the next leader of the uk's conservative

party, who will automatically become the new british prime minister. a broad field was whittled down to two. foreign secretary liz truss, former chancellor ritchie sunak. queen elizabeth will announce the winner. live from london, what are we expecting over the next two days? >> reporter: this leadership racy is actually the culmination of a race that's been taking place for the better part of two months now. because of the peculiar way the conservative party actually chooses its leaders, most of the canned candidates were eliminated in the first few days. when boris johnson announced he would be stepping down, it was the sitting conservative party mps who voted on a series of ballots to get the field down to two, foreign secretary liz truss, and the former chancellor ritchie sunak, the man whose

resignation arguably sparked the beginning of the end of boris johnson's time in power. the criticism is that the mps don't necessarily represent the wider conservative party membership. similarly, the conservative party membership doesn't necessarily reflect the wishes of the wider electorate or even those who are likely to vote conservative in the next election. so despite the fact that you had a field of candidates initially that was the most diverse in british history for any political party, the conservative party members actually doing the choosing are not. according to a 2008 study, 97% of party members are white, 71% male, 61% over 55. there are 180,000 members, which means they make up less than one half of one percent of the electorate. before the other major parties get self-righteous, the same study found this is largely the same across all the political parties. all are majority male when it comes to memberships, all more

than 95% white, and generally, most of the members are quite wealthy as well. so if you believe the polls, kim, liz truss is likely to be named the prime minister tomorrow. she will be officially taking over tuesday when she flies with boris johnson to scotland for the queen to ask her formally to form a government, and after that she has a laundry list of challenges to take care of. inflation, cost of living, rising cost of energy bills. that one the british press is reporting she will have an announcement on very soon. of course, she has plenty of other ideas. but that one is likely to be the one that will get the most scrutiny out of the gate. >> yeah, absolutely. scott, boris johnson, what's next for him? are you expecting a comeback? >> yeah, so british politics is peculiar, especially when you compare it to american politics, in that it is not uncommon for former prime ministers to continue on sitting as regular mps.

theresa may, for instance, is still a sitting mp. boris johnson, it is expected, will continue to sit as an mp at least until the next election. johnson was an author, a columnist, a former mayor of london before he actually got into federal politics and became the prime minister. and plenty of his friends and colleagues who spoke with cnn find it a little hard to believe he wouldn't try for a political comeback if the opportunity to get back in number 10 downing street were to present itself, whether he actually could win a general election or even a leadership race within his own party is really quite another question because of all the challenges that are facing the country as he leaves office. >> it will be interesting to see. scott mcclain in london, thanks so much. just ahead for our viewers here in north america, we'll take a look at the political scene in pennsylvania where several high-stakes races are shaping midterm election campaigns in the u.s. for our international viewers,

♪ he's an enemy of state, you want to know the truth. the enemy of the state is him and the group that control him, which is circling around him, do this, do that, joe, you're going to do this, joe, right? >> that was the moment on saturday when a former u.s. president accused the current president of being an enemy of the state. donald trump launched a counterattack in pennsylvania hit back after president joe biden slammed trump and his maga allies as an extremist threat.

trump was in the keystone state campaigning for candidates for governor and u.s. senate. the state is crucial for this year's midterms but trump appears to be looking ahead to 2024. for more, here's cnn's kristen holmes. >> reporter: former president sdwrump went into pennsylvania to support two of his hard-picked candidate, drug mastriano and it sounded like a stump speech. it went over two hours, focusing mostly on his accomplishments in office, anecdotes, hillary clinton and the fbi. he responded to the search of his mar-a-lago home at length, take a listen. >> the biden administration invaded the home of their chief political opponent, who is absolutely destroying him and everyone else in the polls, i hate to say it. but our opponents have badly miscalculated.

this egregious abuse of the law is going to produce a backlash the likes of which nobody has ever seen before. >> reporter: trump's appearance comes days after we saw president joe biden in the state, showing you how critical the state has become in 2022, particularly when you look at the retiring republican pat toomey. democrats say they believe it is one of their only opportunities to pick up a seat as they cling on, hoping to keep that majority. >> joining me from allentown, pennsylvania, charlie dent, cnn political commentator and former republican u.s. representative from pennsylvania. thank you so much for being here. i want to start with what we saw there. donald trump's speech, trump calling biden an enemy of the state who looked like the devil, accusing the fbi of trying to destroy the country. and particularly sort of in the

context of joe biden's own speech two days ago in pennsylvania, after which republicans criticized biden for this sort of us versus them rhe rhetoric. >> it seems that the country is hopelessly polarized. president trump is in wilkes-barre tonight as you indicated. he's up there criticize is the fbi. have to be honest, any member of congress absconded with classified material, i can assure you that a g-man, somebody from the fbi, would have showed up at their homes and demanded they return that information. so i'm not so sure that the former president trump did anyone any good with that speech tonight. just by showing up in pennsylvania, he is making the election much more about himself. and of course, most republican candidates don't want anything to do with donald trump in this general election. they want this to be about joe biden and the democrats. but to the extent trump inserts

himself into this conversation, he's giving the democrats a major gift right now. that's what we're witnessing in pennsylvania. mehmet oz and doug mastriano were there, mehmet oz i don't think wants to be anywhere near donald trump in this fall election. this doesn't do him any good. he needs to win swing voters, independents, and some democrats. it's hard to do that when trump is pandering to the base. >> let's back up a bit and look sort of at the importance of these races in pennsylvania for senate and governor. how important are they as bellwethers that can tell us a lot about the state of national politics, for instance? >> well, pennsylvania is really probably the most -- certainly the largest swing state in the country. this is a year, too, where republicans going into the election felt pretty good. but again, former president trump inserted himself into the

primary election in both the senate and gubernatorial races, endorsing candidates. i would say the gop establishment really were not behind, certainly in the governor's race case, endorsing mastriano, who's been quite an election denier and extreme on many levels. many republicans view that these races are very winnable, especially in the governor's case. it's not so winnable now because of this candidate, mastriano. i have endorsed josh shapiro, the democrat running against him, a mainstream individual, a decent and honorable human being. >> i know a lot of sort of mainstream, middle of the road-republicans have done that as well. you talked about the importance of donald trump maybe acting as an anchor for these candidates. let's talk about joe biden. he's given several speeches in the state. he's expected back there on monday. is he an important factor with

his sagging poll numbers? could he drag down the democratic candidates? >> well, sure, absolutely. in fact, that's what a midterm election is supposed to be about. the president who is in power and his party. in this case, joe biden and the democrats. and you want the election to be a referendum on them, on joe biden and the democrats. and i think really the key factor in this upcoming midterm election will be joe biden's approval rating. this ticked up a little bit recently. it's not not very good. better than donald trump's ratings. but yes, ordinarily by historic standards, democrats some face some real problems in this midterm. but there have been mitigating factors. the dobbs decision on abortion. the january 6th hearings. the search of donald trump's home down at mar-a-lago and his absconding with classified material. to the extent donald trump is out on the stump. again, i don't think that's helping. plus, of course, many, too many

extreme candidates in some swing straights like doug mastriano in pennsylvania, others in other states who have gotten through the primary process and who are just either unelectable or are certainly deficient in so many ways. so really, so the democrats should be in a much more defensive position than they are. but i wouldn't bet against history. i still suspect republicans will win the house, but not by the type of majority they were talking about a few months ago. obviously, republicans in the senate are facing an even bigger challenge, given some of the candidates who have been nominated this cycle. >> and we just had on the screen a few moments ago some footage from joe biden's speech on wednesday in which he was sort of attacking maga republicans and as i said, a lot of republicans took that amiss, saying he was painting them all with this brush. as a moderate republican yourself, did you sort of take offense to that? did you think that was a bad idea? >> look, i thought joe biden's

use of the term "semi-fascists" was rather -- was very incendiary. i never liked it when republicans would try to paint all democrats as socialists. you know, calling them -- if you want to call those "semi-socialists" or "semi-communists." i thought that was a bit incendiary. >> fascinating races in a crucial state. the country will be watching. thanks so much for your analysis, charlie dent, really appreciate it. >> thanks, kim. they arrive by the hundreds almost daily, often with only the clothes on their back. we'll tell you how much the state of texas has spent to bus thousands of migrants to far-away u.s. cities. nearly a decade after 43 mexican students went missing, they'll follow their grieving parents as they travel to mexico city to demand justice for the crime and the cover-up. steakburs and chicken sandwiches. there's a perfect plate for everyone. great value for all your favorites only from ihohop.

since late april, texas has spent millions of dollars to send thousands of migrants to far-away cities in other states. many crossed the border after long and dangerous journeys and are willing to accept the free bus rides without knowing what's at the other end. cnn's polo sandoval has the latest. >> reporter: the texas division of emergency management, the entity tasked with carrying out texas governor greg abbott's migrant bus program, confirming for cnn that since the start of the program they have spent roughly $12.7 million in state funds to offer these bus rides to migrant families to cities including washington, d.c., new york, and most recently, chicago, illinois. typically these migrants, after they're released from federal custody, it is up to them to pay for their own bus or plane tickets as they continue with their asylum proceedings. however, since april, governor abbott has been offering these

migrants free rides to those who volunteer to accept the offer. governor abbott releasing a statement responding to this reporting showing the $12.7 million in texas taxpayer spending, saying that until president biden and congress do their jobs and secure our southern border, texas will continue utilizing every strategy to address this border crisis and protect texans. we should note, not long after that statement was issued, at least two buses from texas pulled into chicago, transporting about 95 migrants. and the texas governor made clear that he's considering other blue cities in terms of potentially sending migrant buses their way as well. polo sandoval, cnn, new york. hundreds of protesters took to the streets of mexico city on saturday to protest the leadership of president andres manuel lopez obrador and the struggling economy.

started some 200 miles away. a nearly five-hour drive-thru winding mountainous roads deep into the mexican state of guerrero. heavily infiltrated by corruption and cartel violence. the u.s. government warns its citizens not to travel here. along this highway that cuts through the state capital, you can see the graffiti of activism. people demanding justice for their friends. the 43 attended a teachers college near the small town of iotsinapa. here they educate the mostly impoverished, rural, indigenous communities and inspire activism. these are among the last images recorded of the young men, seep learning farming skills, laughing, smiling, just days before the horrors that unfolded on september 26th, 2014. while on their way to commemorate a deadly protest

from decades earlier, the bus carrying the students was reportedly stopped by police. rare footage from one of the students only shows the start of the encounter. what happened next is shrouded in mystery and tragedy. police reportedly opened fire, and 43 of the students, gone. government officials initially concluded local police detained and handed the students over to members of a local cartel who then murdered them and incinerated their bodies. their parents have never believed that.

♪ it can be a terrifying sight, spotting a shark while swimming in the ocean. researchers say the sharks aren't really there looking for you. turns out sharks actually like the waters near big city beaches. cnn's lynda kinkade has the story. >> reporter: every year, millions crowd the white, sandy beaches of florida's southern coast to sunbathe and take dips in the cool atlantic. and just below the surface, a diversity of shark species. sharks have been around for over

450 million years. but have only experienced large urban areas for a few hundred years. scientists at the university of miami wanted to find out if sharks are attracted to or repelled by big cities. >> what we were trying to do is track these sharks to see if they would be avoiding areas really close to the city that were polluted, lots of boat traffic, lots of human disturbance. and we really thought they would. >> reporter: using acoustic technology, researchers monitored the moms of bull sharks, nurse sharks, and great hammerhead sharks off the coast of miami for several years. >> essentially what we did is placed these transmitters, small little tags on the sharks. they're about the size of a aa battery. they would emit an ultrasonic sound. >> reporter: the sound included a code that identifies each shark. they then place listening
