chief executive has resigned. jaunty music plays. and britain's oldest amateurfilm—making club — bradford's movie makers are finally getting the red carpet treatment themselves. 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 entre 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 and not equipment ukraine can use against them. 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. well, earlier i spoke to steve pifer, a senior fellow at the brookings institution and previously us ambassador to ukraine. i asked for his assessment of the significance of the russian retreat from kherson. well, i think that the russian retreat from kherson is significant both in military and political terms. first of all, kherson was the only place in ukraine where there were russian forces on the western side of the dnipro river, which roughly bisects ukraine. they're now pushed back to the eastern side. that's good news.

it means, for example, that there is much less of a threat that the russian military may strike out from mykolaiv or 0dessa. but i think it's also politically a huge setback from the kremlin. just six weeks ago, vladimir putin announced that he was annexing kherson, along with three other ukrainian oblasts — regions — and six weeks later, you have this spectacle of the russian literary withdrawing from the capital of the kherson region. that's gotta go down badly in moscow. he, of course, is calling it a redeployment and it's a manoeuvre, it's a tactic. well, this has been the standard russian term for what most other military experts would consider retreats. a redeployment, a manoeuvre, a regrouping — things like that. but people understand this is a humility retreat by the russian military. so, there must be concern, though, now, though, of what putin will do to sort of save face, i suppose, in face of this.

people haven't been talking so much about nuclear recently but is that still a threat that people should be thinking about right now? well, you have to take it seriously when vladimir putin talks about nuclear weapons but i think that there are real reasons why we can minimise that concern. one is, first of all, putin doesn't want a nuclear war. he wants ukraine and the west to think he's ready for a nuclear war in order to intimidate ukraine into ceding to russian demands and in order to intimidate the west to cutting off supplies of weapons to ukraine. but one, it's pretty clear that the ukrainians would continue fighting, even if the russians used a nuclear weapon in ukraine. two, the west have made very clear there'd be hugely serious consequences. and three, i think the russians understand that if they were to use a nuclear weapon now, they would lose the global south, including india and china. and just last week, the chinese came out — president xi himself — criticising irresponsible nuclear threats. so, i think there are real reasons why the russians

understand that it would be a huge mistake for them and for russian interests to use nuclear weapons at this point. 0kay. and in terms of the immediate future, we have winter sort of getting tougher and tougher — for both sides, i suppose — but where do you see this playing out? i mean, are the people celebrating in ukraine tonight right to be thinking that this has brought the end of the war a step closer? well, certainly, it means the liberation of more ukrainian land from russian occupation, so i can understand the celebration. we'll have to see. the winter will change the conditions for fighting but i'm not sure if the ukrainians see an opportunity that they might not continue the counteroffensive. i mean, their goal is to liberate as much land as they can. ideally, they want to drive the russians out or, at a minimum, get to a point where there is a negotiated settlement on terms that kyiv could accept. and right now, moscow's demands for a negotiation, thus far, don't reflect the

realities on the battlefield, which is that russia has been losing this war now for almost three months. 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 watch—list. 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. divers working with a documentary crew off the eastern coast of florida have found a 20—foot section of the space shuttle challenger, which exploded, and broke apart, shortly after its launch in 1986. the find marks the first time

in 25 years that a piece of the challenger has been located. nasa says it's one of the largest sections that's ever been found. 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 of the house of representatives. 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, they will take responsibility. # why can't you see... but losing the house will make it difficult for the us to come up with cash for international climate action. the poorest developing countries are often hit hardest by climate change —

like south sudan, where a drought is adding 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.

after the brief stopover in egypt for the c0 p27 conference, joe biden has touched down in phnom penh for the asean summit. the president is to hold separate meetings with the leaders of cambodia, japan and south korea, ahead of next week's g20 meeting in indonesia. you are watching bbc news. a reminder of our 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. president biden urges countries at the cop27 climate summit in egypt to raise their ambitions, saying the us is on track to meet its own targets. france and italy have been trading criticism over the handling of a migrant rescue ship. the ocean viking, which had 230 people on board, has been allowed to dock in the french port of toulon, after being refused entry to italian ports. mark lowen reports from rome. arriving into safe harbour but sailing into a diplomatic crisis between france and italy, the ocean viking, which rescued migrants coming

from libya but whom italy and so, france agreed to welcome the ship instead. the migrants on board had been blocked for days. italy finally allowed three other vessels to dock, declaring france would take this one, but it seems paris hadn't agreed, seeing italy's announcement as a way of forcing a deal — behaviour it called "reprehensible". translation: many | people were very sick. italy has been very inhumane in handling the situation. the italian authorities were not professional. they left this boat there for 20 days without making any decisions. italy's new prime minister, giorgia meloni, hit back. the country has long argued it unfairly bears the migration burden. but there's also domestic politics here, with a far—right leader wanting to please her base. translation: i was struck by the aggressive reaction l from the french government — which, from my point of view, is incomprehensible

and unjustified. what exactly makes them so angry that italy must be the only possible port of disembarkation for migrants in the mediterranean? i don't think that's right. some on board had to be flown to a french hospital. italy says almost 90,000 migrants have arrived here this year, while the ocean viking is the first ngo boat france has accepted. but the french far—right still seized the moment, condemning president macron�*s move. translation: he makes people believe that he is opposed - to massive and illegal immigration when, in reality, he is its defender, its promoter and, if i may say so, this act, this decision that has just been taken is the greatest symbol of it. this was the moment the migrants heard they'd be allowed into france after a treacherous journey and days blocked at sea. the latest pawns in the migration battle dividing the eu.

theirjourney for now may be over, but the storm between two eu allies is whipping up. mark lowen, bbc news, rome. 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 crypto currency exchange ftx is 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 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 _ they exist in crypto. the problems began - they exist in crypto. the problems began last - they exist in crypto. the problems began last week. with questions raised about the company's financial structure. compa ny�*s financial structure. the uncertainty led company's financial structure. the uncertainty led to a run on the exchange, similar to a run on a bank where people brace to take up their money.— take up their money. there is a anic take up their money. there is a panic that _ take up their money. there is a panic that customers, - take up their money. there is a panic that customers, people i panic that customers, people who have money or have assets with ftx would not be able to withdraw it and so, they all rush forward with the withdrawal window at the same time. ~ ., , ., "~ time. within 24 hours, about $5 billion was — time. within 24 hours, about $5 billion was withdrawn. - time. within 24 hours, about ssj billion was withdrawn. attempts at her ballot 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 had been something of a cult hero of the crypto scene. atjust 30 years old, he had built a net worth of around $15 billion. bloomberg is now estimating that has dropped to

just $3. not 3 billion, at $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. so, what's gone wrong? techcrunch reporter anita ramaswamy explains the day's events. i mean, it's is a complicated story but the 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. overnight, the company essentially went from a darling of the crypto industry that everyone thought was very stable to being something

which came underfire 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 its 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? it shows you how vulnerable it is. yeah, it happened 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 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?

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 actually are 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 people around the world and it will 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, won't it? it already has but, 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, 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. 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 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 film—making 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. our arts correspondent david sillito went along to meet them. we are a group of keen amateurfilm—makers. jaunty music plays. the bradford movie makers. 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 oklahoma, where i am 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? ooh!

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 whenjoe, a disability support volunteer, posted a message online about loneliness and isolation. you talk about very personal things in this, depression... 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 continues. 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 voice—over community has lost one of the greats." and dc comics said they were "deeply saddened" by the news.

that's all from me for this half now —— half—hour. you can reach me on twitter. i'm @lucyegrey. thank you for watching. hello. this exceptionally mild weather is producing some remarkable temperatures — 19.5 degrees celsius 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 258

millimetres 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 the 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, 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.

this is bbc news, the headlines: crowds have cheered ukrainian troops as they entered kherson after russia's retreat — the city had been occupied by russia since march. it's been hailed as an historic day by the ukrainian president, volodymyr zelensky. thousands of russian troops have retreated across the dnipro river. president biden has told the cop27 climate summit that he wants to re—establish the us as a reliable global leader on tackling climate change. he said he's committed to the target of halving us carbon emissions by 2030 and apologised for donald trump pulling out of the paris climate accord. one of the world's largest cryptocurrency exchanges, ftx, has gone bust and filed for bankruptcy in the us. the firm has been struggling to cope with investors attempting to withdraw billions of dollars from its online platform.
