chanting. kherson�*s residents emerged from their homes as the first ukrainian soldiers reached the main square. 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.

this is the mood here in the centre of kyiv tonight, a night of celebration of 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. it's certainly one of the most significant reversals for the russians. president zelensky says ukrainian forces are nowjoining in 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. believed was possible. but this war is farfrom over. this is a city that 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. while moscow has described the troop withdrawal as a "military manoeuvre," it's been seen by many analysts as one of the most significant failures of russia's invasion of ukraine. president putin has tried to distance himself from the decision. here's our russia editor steve rosenberg. russian officials are not calling this a retreat. they are calling it a redeployment, a manoeuvre, trying to play things down a little bit. but that doesn't alter the fact that this was a withdrawal from the only ukrainian provincial capital that the russians managed to capture since february,

and it came just a few weeks after president putin had declared that kherson had become part of russia forever. so, yes, this is embarrassing, i think, for vladimir putin. it is a blow to the russian president, which is probably why the kremlin has been trying to distance him from the decision to retreat because it knows that the pull back will be seen as a setback by many people in russia. it doesn't want the president taking the flak — that is why the russian generals had to go on television earlier this week. it was left to them to announce this withdrawal to the russian people. but, at the end of the day, who is the commander—in—chief in russia? it is vladimir putin. whose idea was it to invade ukraine? vladimir putin's. so, it's hard to imagine that at some point, vladimir putin won't be caught up in the consequences of and the fallout from this war, whatever they may be. we can now speak to steve pifer, who's a senior fellow

at the brookings institution and was previously us ambassador to ukraine from 1998-2000. thank you forjoining us here. what's your assessment of the significance of all of this? well, i think that the russian retreat in 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 are now pushed back to the eastern side. that's good news. it means for example there is much less of a threat that the russian military may strike edessa. it also is politically a huge setback, just six weeks ago vladimir putin announced he was annexing everyone, along with three other ukrainian oh busts —— 0desa. regions. in six weeks later you have these articles of the russian

literary withdrawing from the capital of the region which has to go down badly in moscow —— oblasts. it is calling it a redirection and a tactic. 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. retreat by the russian military-— retreat by the russian milita . , , military. so there must be concerned _ military. so there must be concerned now, _ military. so there must be concerned now, though, l military. so there must be| concerned now, though, of military. so there must be - concerned now, though, of what vladimir putin will do to save face, i suppose, vladimir putin will do to save face, isuppose, in vladimir putin will do to save face, i suppose, in the face of this. people have not been talking so much about nuclear recently but is that still a threat to people should be thinking about right now? well, ou have thinking about right now? well, you have to _ thinking about right now? well, you have to take _ thinking about right now? well, you have to take it _ thinking about right now? well, you have to take it seriously - you have to take it seriously when vladimir putin talks about nuclear weapons but i think the real reasons why we can minimise that concern and one is first of all priddin does not want a nuclear war, he wants ukraine and the rest of think is ready for a nuclear war in order to determine that

ukraine into ceding to russian demands —— putin. 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 and two, the west made it clear there would be 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 criticised 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. to use nuclear weapons at this oint. �* , ., point. and in terms of the immediate _ point. and in terms of the immediate future, - point. and in terms of the immediate future, we - point. and in terms of the l immediate future, we have winter sort of getting tougher and tougherfor winter sort of getting tougher and tougher for both sides, i suppose, but where do you see this playing out? other people celebrating in ukraine tonight right to be thinking that this has brought the end of the war a step closer?—

a step closer? well, certainly, it means _ a step closer? well, certainly, it means the _ a step closer? well, certainly, it means the liberation - a step closer? well, certainly, it means the liberation of - a step closer? well, certainly, | it means the liberation of more ukrainian land from russian occupation, so i can understand the celebrations. we will have to see was not 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 want to drive the russians out orata minimum want to drive the russians out or at a minimum get to a point where there is a negotiated settlement on terms that kyiv can accept and right now, moscow's demands by negotiation, thus far, don't reflect the realities of the battlefield, which is that russia has been losing this war now for almost three months. very good to get your thoughts, thank you so much. steve pifer. 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. divers 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 they've ever found. 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. 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 heat waves 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. 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. 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 refused to take in. 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. one of the world's biggest

cryptocurrency exchanges, ftx, has begun bankruptcy proceedings in the united states. the firm has been struggling to deal with investors attempting to withdraw billions of dollars from its online platform. for more on this, we can speak to anita ramaswamy, who is a senior crypto reporter at techcrunch. can you just explain why this collapse of ftx has happened? absolutely. it 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 raised questions about ftx's solvency. overnight the company essentially went from a darling of the crypto industry which everyone thought was very stable, to being something which came under fire and under question because of the close ties that it had to its sister entity alameda research, and a lot of its value was locked up in its own

token, so ftx had created this token, so ftx had created this token called ftt, and a lot of its value was based on the value of ftt which is not backed by anything.- value of ftt which is not backed by anything. and it is extraordinary _ backed by anything. and it is extraordinary how _ backed by anything. and it is extraordinary how quick - backed by anything. and it is extraordinary how quick this | extraordinary how quick this all happened, isn't it, it shows you how vulnerable it is. it happened so fast, and nothing is ever as it seems in crypto, this happened seemingly overnight and sam bankman—fried, the founder of ftx was held in very high regarding the crypto industry. he was seen as a figurehead for the entire secular, and so 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 reveal that to the public, is very troubling.— reveal that to the public, is very troubling. so what was it, did he stretch _ very troubling. so what was it, did he stretch himself- very troubling. so what was it, did he stretch himself too - did he stretch himself too thin, did he try to do too much, what was the problem? i believe there was a little bit more intent behind it than that. new information is coming to light every single day on this topic at this point, but

they had raised, and 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 has been some evidence to show that they might have improperly used customer funds to cover some of that shortfall.— that shortfall. and the important _ that shortfall. and the important issue - that shortfall. and the important issue of - that shortfall. and the - important issue of customers and what happens to them, and in terms of getting their money back? ., in terms of getting their money back? . ., , back? yeah. right now it is uncertain — back? yeah. right now it is uncertain if _ back? yeah. right now it is uncertain if it _ back? yeah. right now it is uncertain if it is _ back? yeah. right now it is uncertain if it is unclear. i back? yeah. right now it is. uncertain if it is unclear. ftx halted withdrawal and the 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 tried to get their money out today 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 they were located outside of the bahamas, getting people in the bahamas, getting people in the bahamas, getting people in the bahamas to take out crypto and 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

you that ftx is actually going to be able to return this money to be able to return this money to customers, especially if they go through bankruptcy. what can crypto firms do to try and restore confidence, because this is going to do a lot of damage? it this is going to do a lot of damage?— this is going to do a lot of damate? . . , , this is going to doalot of damate? . . , , ., damage? it already has, but at the end of— damage? it already has, but at the end of the _ damage? it already has, but at the end of the outcomes - the end of the outcomes and transparency. you see a lot of firms in the coming weeks released approve exams, 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 the space and transparency is really lacking, thatis transparency is really lacking, 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. thank you for talking us through it, anita ramaswamy. 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

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 has 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 the showbusiness 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. 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, for my sins. 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 are all going to get old, we are all going to be looking for something to do with our minds, we are 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 is the main event, the hometown gala premiere.

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 told the bbc the voice—over community has lost one of the greats, and dc comics said they were deeply saddened by the news. you'll find lots more deatil and analysis on our website, including the situation in kherson — just head to bbc.com/news or download

across northern areas, and yet more rain in the highlands. in fact, taggart 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. and 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 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 and 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.
