from the space shuttle challenger that exploded after takeoff in 1986. and britain's oldest amateurfilm making club, bradford's movie makers, are finally getting the red carpet treatment themselves. hello and welcome to the programme. it's been hailed as an historic day by ukraine's president after what's being seen as a humiliating withdrawal of russian forces from the southern city of kherson. thousands of russian troops have retreated across the dnipro river, leaving the way open for ukrainian special forces to enter the centre of kherson. residents waved the national flag and embraced troops in the main square, chanting "glory to ukraine!" our international editor, jeremy bowen has been following the situation

from southern ukraine. chanting kherson�*s residents emerged from their homes as the first ukrainian soldiers reached the main square. chanting continues for them, it's the end of more than eight months under occupation. plenty to celebrate, but they are not out of danger. russia's guns are only a few miles away across the river. as they left, russian engineers blew a section of the antonovski bridge over the dnipro. at dawn, long lines of russian troops seemed to be using a temporary crossing under the main damaged structure. the russian claim is that 30,000 soldiers and more than 5,000 pieces of equipment left kherson before the bridges were blown. the ukrainian forces pushed forward.

the final russian departure happened much faster than anyone expected. we received these pictures from a special forces unit, taken as they poked around a camp the russians had abandoned. here, at least, this retreat looks better organised than some of russia's others in ukraine — that's because, apart from a few dozen shells, most of what they left was rubbish president zelensky told ukrainians that this was an historic day — they were taking their country back. cheering. the people of kherson kept the liberation party going. what's happened deepens the ukrainian conviction that they can beat russia. ukrainians can celebrate tonight. there'll be harder times ahead. jeremy bowen,

bbc news, in ukraine. ukrainians have been celebrating across the country. 0ur chief international correspondent, lyse doucet, reports from the capital, kyiv. singing this is the mood here in the centre of kyiv tonight — a night of celebration on what president zelensky describes as an historic day. look at the banners they are holding here, "kherson is ukraine," written in the colours of the ukrainian flag. they have been singing here for hours, singing popular songs like this, singing the ukrainian national anthem. this is the most significant victory for ukrainian forces in some time and certainly one of the most significant reversals for the russians. president zelensky says that ukrainian forces are now joining its special units in the centre of kherson. we've spoken to people here tonight who believe that moments like this are bringing the end of the war closer, bringing them closer to the victory they have always believed was possible.

but this war is far from over. this is a city which is suffering from power cuts because of russian strikes on the energy infrastructure. it also suffers from russian attacks. and the concern is that with this humiliation yet again for president putin's forces, it's just a matter of time before he strikes again. but that's not on the mind of these celebrations tonight. lister said reporting from kyiv. let's get some of the day's other news. the us official responsible for overseeing border security says he has been asked to resign, or be sacked. chris magnus, who has been customs and border protection commissioner for less than a year, says he is refusing to go. he has defended his work, despite a record number of illegal border crossings. police in belgium are planning to protest after an officer was stabbed to death,

allegedly by a man who was on a terrorism watchlist. another officer was wounded in the attack in brussels on thursday. the suspect is said to have walked into a police station earlier in the day, expressing his hatred for the police and asking for psychological help. a british man has admitted spying for russia while working as a security guard at the uk's embassy in berlin. prosecutors accused david smith of being motivated by intense hatred of britain. he'll be sentenced next year and faces up to m years in prison. mark kelly — the us democratic senatorfor arizona — has beaten off a republican challenge for his seat in the us congress. his defeat of blake masters means that the two parties are now neck and neck in the race for control of the senate. two more seats are to be declared, one in nevada and the other in georgia. georgia's result won't be known till december, when a run—off election takes place. 0ur north america correspondent david willis joins me now from washington.

the upper house. but this is very good news for the democrats. they also, of course, have been widely predicted to lose a lot of seats in the house of representatives and it appears that that's not been the case either. , ., , ., either. they only need one more, either. they only need one more. don't _ either. they only need one more, don't they? - either. they only need one more, don't they? one - either. they only need one l more, don't they? one more either. they only need one - more, don't they? one more seat to have a majority, because the vice president has that tie—breaking vote, doesn't she? just explain, we know the georgia run—off is on 6 december, when do we hearfrom nevada? december, when do we hear from nevada? ~ , ., , nevada? well, they are still countin: nevada? well, they are still counting in _ nevada? well, they are still counting in nevada, - nevada? well, they are still counting in nevada, lucy. . nevada? well, they are still l counting in nevada, lucy. and it could be a matter of days before we get the result from there. it is said to be very close, with the democrats getting a slight lead over her republican challenger, adam laxalt in that race. a very tight race. she was the first latina elected to the us senate, and she has been defending that seat quite doggedly there in nevada. 0f

doggedly there in nevada. of course, following their victory in pennsylvania the other night, the democrats had plenty of hope. there wasjohn letterman overcoming the donald trump endorsed canada, mehmet oz, that was a victory for the democrats, they seem to be sitting fairly pretty now and few would have predicted this just a week or so ago. the challenger _ just a week or so ago. the challenger in _ just a week or so ago. the challenger in arizona - just a week or so ago. the challenger in arizona was a candidate himself backed by president trump. so it is another disappointment for him on the fact that another one of those people that he endorsed hasn't got in. those people that he endorsed hasn't got in-— hasn't got in. that is right, blake masters, _ hasn't got in. that is right, blake masters, a - hasn't got in. that is right, blake masters, a trump i hasn't got in. that is right, - blake masters, a trump endorsed venture capitol still had to be bailed out, as far as the financing was concerned, towards the end of the race there. and you are right, it was a night, tuesday, when a lot of trump endorsed candidates underperformed, if you like, and that has led to a lot of criticism of the former

president, mrtrump lot of criticism of the former president, mr trump himself. and his so—called kingmaker abilities. some are saying now that maybe this is not the time for him to run for president again. he, nonetheless, is intending to make an announcement to that effect, it is widely thought, tuesday of next week. is widely thought, tuesday of next week-— is widely thought, tuesday of next week. , , ., next week. ok, we will see you. david willis _ next week. ok, we will see you. david willis therefore _ next week. ok, we will see you. david willis therefore us - next week. ok, we will see you. david willis therefore us in - david willis therefore us in washington. thank you. president biden has urged countries at the cop27 climate summit in egypt to "write a better story" for the planet. he said the us had passed major climate legislation and was on track to meet its own targets and that other countries had to raise their ambitions. 0ur climate editorjustin rowlatt sent this report from the conference in sharm el—sheikh. another hurricane smashed into florida today — yet more wild weather for the us. it has endured heatwaves and wildfires and some epic floods. as president biden arrived in the egyptian desert, he claimed his climate policies will drive down emissions and transform the us.

we're proving that good climate policy is good economic policy. it's a strong foundation for durable, resilient, inclusive economic growth. it's driving progress in the private sector. it's driving progress around the world. nancy, have you got a moment to speak to the bbc? the american midterm election results were better for the president's party than some pundits predicted... we are less than a minute away, ma'am. ..but the democrats still look likely to lose control oh, there you are! yes! the house speaker says she hopes the republicans will become more cooperative on climate. we didn't get one republican vote but i would hope that when they have more responsibility and more opportunity, # why can't you see... but losing the house will make it difficult for the us

the poorest developing countries are often hit hardest by climate change — to the chaos of war. they say the us isn't paying its fair share. we want us to be on board. we want to be all together — all countries have to be on board. that may be, but the us and china have stopped cooperating on tackling global warming. this is china's pavilion at the conference. it now talks about competing with the us on climate. it wants to keep its lead on renewable technologies like wind turbines, solar panels and batteries. the us uses similar language. it talks about overtaking china on clean tech. but this could be good news —

it could mean cheaper renewables and maybe even generate a rush to find finance for developing nations. as president biden leaves egypt tonight, the hope is superpower competition on climate could bring progress. justin rowlatt, bbc news, egypt. this is bbc news. the headlines: crowds cheer ukrainian troops as they enter kherson after russia's retreat. the ukrainian president hails it as an historic day and thousands celebrate. the democrats now appear to be one seat short of keeping control of the us senate as mark kelly is projected to hold on to his seat in arizona. divers from a documentary crew have found a large piece of wreckage from the space shuttle challenger. the discovery off the eastern coast of florida marks the first time in 25 years that a piece of the challenger has been located. naomi choy smith reports. this was the moment divers made an incredible discovery of cape canaveral. a 20 foot section

from the space shuttle challenger which exploded after launch in 1986. divers were hunting for the wreckage of a world war ii aircraft as part of a history channel documentary, but what they are most instead left them stunned. we were not expecting that. it we were not expecting that. it was an accidental discovery and one we were not prepared for at the time and we were all stunned for it.— stunned for it. the challenger's - stunned for it. the - challenger's distinctive heat tiles mostly didn't understand. nasa says it is one of the light of this of the wreckage had everfound. light of this of the wreckage had ever found.— had ever found. ten, nine, eiuht, had ever found. ten, nine, eight, seven... _ had ever found. ten, nine, eight, seven... the - had ever found. ten, nine, - eight, seven... the challenger broken apart — eight, seven. .. the challenger broken apart after— eight, seven... the challenger broken apart after liftoff - eight, seven... the challenger broken apart after liftoff from | broken apart after liftoff from kennedy space centre, killing all seven crew members on board. and liftoff. it was one of the worst disasters in the history of the us space programme. pieces of the shuttle were recovered from the ocean after the accident. then a decade later, some sections washed up following a storm.

building codes were introduced. the cryptocurrency platform ftx has gone bust and its chief executive sam bankman—fried has resigned. worries about ftx have caused huge problems for crypto investors recently. ftx is one of the biggest and has gone under despite attempts by another huge exchange, binance, to rescue it. tom brada reports. once a star of the crypto world, its reputation is now in tatters. the cryptocurrency exchange ftx has filed for bankruptcy in the us, shaking confidence in the sector and leaving thousands of customers worried about their money. i think it's undeniable that this is a black eye on the crypto industry. this was seen as an incredibly established, blue—chip company — to the extent they exist in crypto. the problems began last week with questions raised about the compa ny�*s financial structure. that uncertainty led to a run on the exchange — similar to a run on a bank,

where people race to take out their money. there is a panic that customers — people who have money or have assets with — in ftx would not be able to withdraw it, and so, they all rush for the withdrawal window at the same time. within 2a hours, about $5 billion was withdrawn. attempts at a bailout failed and so, on friday, the ceo of ftx announced they are filing for bankruptcy. sam bankman—fried has now stepped down as chief executive. before this meltdown, he'd been something of a cult hero of the crypto scene. atjust 30 years old, he'd built a net worth of around $15 billion. bloomberg is now estimating that's dropped to just 3. not $3 billion, but $3. his fall from grace marks a perilous moment for the crypto world. other exchanges have failed before, but nothing on this scale.

ftx is reportedly under investigation by several financial authorities, but that will be of limited satisfaction to its thousands of customers who are anxiously waiting to know where their money has gone. tom brada, bbc news. for more on what's gone wrong at ftx, i've been speaking to tech crunch reporter anita ramaswamy. i mean, it's a complicated story, but their balance sheet was revealed, essentially, and that report led to the ceo of a rival exchange, binance — which is the biggest crypto exchange in the world — firing off a bunch of tweets that basically raised questions about ftx's solvency. 0vernight, the company essentially went from a darling of the crypto industry, that everyone thought was very stable, to being something that came under fire and under question because of close ties that it had to its sister entity, alameda research, and essentially, they had a lot

of its value was locked up in its own token. so, ftx had created this token called ftt. turns out a lot of their value was just based on the value of ftt, which is not really backed by anything. well, this is the issue, isn't it? and it is extraordinary how quick this all happened, isn't it? i suppose itjust shows how vulnerable it is. yeah, it happens so fast, and it goes to show — i mean, nothing is ever as it seems in crypto. this happened seemingly overnight and sam bankman—fried, the ceo and founder of ftx, was held in very high regarding the crypto industry. he was lobbying in washington. he was seen as a figurehead for the entire sector and so, to see his company fall from grace so quickly and to know that they have these underlying issues this whole time and didn't reveal that to the public is very troubling. so, what was it? did he just stretch himself too thin, then? did he try to do too much? what was the problem? i believe that there was a little bit more intent behind it than that. you know, new information is sort of coming to light every single day on this topic at this point, but they had raised, i mean, an evaluation of $32 billion

as recently as september. so, they were not being honest or transparent with customers about their liquidity position and, furthermore, there's been some evidence to show that they might have improperly used customer funds to cover some of that shortfall. right. and to the important issue of customers and what happens to them, and in terms of getting their money back? yeah. i mean, right now, it's uncertain and it's unclear. ftx halted withdrawals and their us entity also did the same today, so people can't get their money out, and there were some anecdotes because the one jurisdiction that people were able to get their money out today after withdrawals were frozen was in the bahamas, where they are actually headquartered, so some people were sending requests and doing these complicated transactions when they were located outside of the bahamas, getting people in the bahamas to take out the crypto and the funds on their behalf. so, withdrawals have been all but halted for most people

around the world, and it's going to be really tough and only time will tell whether that ftx is actually going to be able to return this money to customers, especially if they go through bankruptcy. i suppose, what can crypto firms do to try and restore confidence, because this is going to do huge damage, isn't it? it already has done a lot of damage, but i think at the end of the day, it comes down to transparency. you see a lot of firms in the coming weeks release their proof of reserves. a lot of exchanges will try to show they have enough liquidity, that they are in a strong financial position. but there are still a lot of private companies in this space, and transparency is really lacking. so, i think that is what is going to differentiate customers who are going to win over customer trust versus those who cannot — people who are providing the most information disclosure as possible. but even then, it will be very hard for the public to regain their trust in crypto after a huge event like this. that's anita ramaswamy there. twitter has started removing fake accounts that have multiplied since elon musk�*s takeover, suspending sign—ups for a new paid checkmark system and reinstating a grey "official" badge on some accounts. us regulators say that they're

concerned about staff upheavals at twitter as top officers for privacy and compliance are among the latest executives to resign. the federal trade commission warned musk that he was not above the law. after more than 90 years of showcasing other people's stories, britain's oldest amateur filmmaking club is finally in the spotlight itself. a documentary about bradford film makers' work has made it to the big screen, and to rave reviews. 0ur arts correspondent david sillito went along to meet them. we are a group of keen amateurfilm—makers. jaunty music plays they've been making films since 1932 with lots of enthusiasm, but not a lot of success. however, things have changed. i would like to remake 0klahoma, where i'm riding a white stallion. the film a bunch of amateurs is a documentary about the club. it tells the story

of people like harry. # oh, what a beautiful morning... ..here doing his version of oklahoma. and the documentary has been getting rave reviews. harry's been all over. you've been to bafta? i've been to bafta. i've been to london twice in this last week. are you getting used to this show business lifestyle? laughs colin has been a member for more than 50 years, and this is his first premiere. this is more my line, you know? it's cine, you know? 0oh! oh, it's dropped out again. this is a special day for you. yeah — oh, yeah. i'm looking forward to it, yeah. but this is about more than just a hobby — a lot of the members are carers. the idea of the film began when joe,

a disability support volunteer, posted a message online about loneliness and isolation. you talk about very personal things in this, depression and... oh, yeah. i've had that for many years, you know? for my sins, yeah. it's filming that i can actually show the story of my life on film if i wanted. i think what happens in this film, we're all going to get old, we're all going to be looking for something to do with our minds, we're all going to be looking for a community, we may lose our loved ones, and i think this club is like an amazing alternative family. big smiles, everybody! and then, there was the main event — the home town gala premiere. applause 90 years of movie—making. there have been no glamorous premieres, many ups and downs.

so, today for the bradford movie makers, it's quite a moment. applause david sillito, bbc news, bradford. kevin conroy, who was best known as the voice of the caped crusader in batman: the animated series, has died at the age of 66. he first took on the iconic role of bruce wayne 30 years ago, and went on to appear in a number of tv shows, feature films and video games. his agent, steven neibert, told the bbc: "the voiceover community has lost one of the greats." and dc comics said they were "deeply saddened" by the news. you'll find lots more detail and analysis on our website, including our main story: president zelensky says russia's retreat from the ukrainian city of kherson is an historic day. just head to bbc.com/news or download the bbc news app for your tablet or smartphone.

there will of course also be updates from the latest on the midterms in the us as well. that is all from me. you can reach me on twitter — i'm @lucyegrey. bye— bye. hello. this exceptionally mild weather is producing some remarkable temperatures — 19.5 degrees celsius at myerscough in lancashire on friday, 19.1 at lossiemouth in moray. so, what's going on? we've got a big dip in thejet stream to the west of the uk and it's around the base of this dip we're drawing up close to the azores some of this exceptionally mild airourway. so, temperatures are so far above average for the time of year. in fact, on thursday night, provisionally, according to the met office, both scotland and northern ireland had their warmest november nights on record. and, of course, climate change is notjust about those big, headline—grabbing daytime temperatures,

it's how far we keep warmth overnight as well. very windy on friday across northern areas and yet more rain in the highlands — in fact, achnagart, since monday, has had 258mm of rain — some months�* worth of rain in a week. a lot of that rain has gone this weekend, keeping the very mild weather. not as windy, though, and that does increase the risk of seeing some mist and some fog. and actually, a cooler start to the day for saturday. in fact, under clear skies in north—east scotland, low single figures in some spots, six or seven degrees in east anglia. with a lot of low cloud and mistiness across a large part of wales and england, northern ireland seeing some overnight rain clearing away as that trundles north across scotland. behind, it will brighten up, though. still the cloud thick enough in a few spots for a bit of drizzle. some eastern parts of england may stay with some low cloud, whereas for much of england and wales, it will turn sunnier. a cooler day, but still very mild for scotland, northern ireland, northern england. through much of england and for wales, we're talking 16 to 18 degrees celsius. and, yes, those lighter winds, allowing more in the way of low cloud and mist and fog

to form as we go overnight and into sunday morning. thick enough for some drizzle in places, particularly through eastern scotland, central and eastern parts of england. a milder start to the day on sunday. so, for remembrance sunday, then, a grey, misty, murky start in many places, and although for many places, it will brighten up and get to see some sunshine, there'll be some spots from eastern scotland and down through central and eastern parts of england that could well hold on to some grey conditions, maybe quite widely into yorkshire. another very mild day out there. wind freshening in the west, some rain to northern ireland as we go on into the evening and the main feature of the weather for the week ahead is that temperatures are going to come down much closer to average. spells of strong winds and heavy rain at times.
