this is bbc news, these are the latest headlines in the uk and around the world. in a phone call with ukraine's leader, president biden says he'll respond "swiftly and decisively" if russia invades the country. more than a dozen countries tell their citizens to leave ukraine. over 100,000 russian troops remain at the border. 13 people are injured after a mezzanine floor collapses at a pub in east london. police have cleared the remaining protesters blocking a key bridge between canada and the united states, after a week of disruption. and people in switzerland have voted in favour of tightening the country's tobacco laws by banning virtually all advertising of tobacco products.

hello and welcome, if you're watching in the uk or around the world. the us says president biden and his ukrainian counterpart, volodymyr zelensky, have agreed on the need to pursue what they called "diplomacy and deterrence" in response to russia's military build—up on ukraine's borders. the two leaders spoke for almost an hour this afternoon as western allies continue to fear an invasion is imminent. 0ur diplomatic correspondent paul adams is in kyiv. we've got this weird phenomenon of apocalyptic warnings from the west, and this odd sense of calm here in kyiv which persists to this day, even days ahead of something that could be pretty grim. i was talking to a ukrainian writer early on who said that effectively, ukrainians were inoculated against fear and panic back in 2014, when the war in the east of the country erupted — that war has gone on ever since and,

if you like, the body politic here in ukraine has been inoculated ever since. and i think people feel that they are used to the cost of war, and they have kind of mentally and psychologically adjusted to it. i think that is psychologically plausible, but i think there are also other reasons. president zelensky is obviously deeply worried that any kind of fear and panic could upset the economy and put off investment that his country badly needs. but i think it's also possible that he's not seeing the same intelligence that the west is seeing — and that could be a problem. let's speak to radek sikorski, former polish defence secretary and former foreign minister. welcome, thanks for being with us. so we know the us is sending 3000 more troops to poland, the pentagon says, to reassure and deter any potential aggression against nato�*s eastern flank. how welcome is that?

billions from their country. they don't do diplomatic language, you have to tell them that we will make ourselves independent of russian guards, it will freeze their assets, and if they do a regime change in new current debts ukraine, we might do a regime change with them, and so on. this must be tougher than what they've done. but on. this must be tougher than what they've done-— on. this must be tougher than what they've done. but they've made clear what options — they've done. but they've made clear what options are _ they've done. but they've made clear what options are on _ they've done. but they've made clear what options are on the _ they've done. but they've made clear what options are on the table - they've done. but they've made clear what options are on the table in - what options are on the table in terms of sanctions and seeking gas elsewhere — you said they need to be far more deliberate about it, and in russia's face?— russia's face? well, live from's dau~hter russia's face? well, live from's daughter is _ russia's face? well, live from's daughter is enjoying _ russia's face? well, live from's daughter is enjoying london - russia's face? well, live from's daughter is enjoying london in l russia's face? well, live from's| daughter is enjoying london in a multi—million pound flat. all the front men who hold putin's money keep it in cyprus and britain, luxembourg, and havana. we should really clean up and exclude russian money also from our politics, you know, we have these people making

incursion into ukraine, and what could it cost putin at home? he doesnt could it cost putin at home? he: doesn't quite have the forces to take on all of ukraine — so my bet will be that if he goes in, he will take the eastern shore, which would be about 40% of the country. if it is bloodless and ev, it will be popular. if you lose is more than 10,000 troops, 300 tanks and 100 aircraft, that it might be the beginning of the end of his resume dashed bloodless and easy. thank you ve much dashed bloodless and easy. thank you very much for— dashed bloodless and easy. thank you very much forjoining _ dashed bloodless and easy. thank you very much forjoining us _ dashed bloodless and easy. thank you very much forjoining us here - dashed bloodless and easy. thank you very much forjoining us here on - dashed bloodless and easy. thank you very much forjoining us here on bbc. very much forjoining us here on bbc news. a busy border crossing between the united states and canada has been cleared by police, after a nearly week—long protest by anti—vaccine mandate protesters. the blockade at the ambassador bridge was part of widespread demonstrations taking place across canada, including in the national capital, 0ttawa. the border point is the first site to be cleared by authorities since the protests began more than two weeks ago. voters in switzerland have backed

legislation banning tobacco advertising anywhere it might be seen by young people. the move will bring the country into line with its european neighbours. 56% voted in favour in a referendum. the north korean leader, kimjong—un, has made a rare public appearance in pyongyang. he was at a ceremony to mark the start of building 10,000 new homes. he promised to prioritise his country's economy and improve livelihoods. north korea has been hit by shortages because of tighter border controls with china during the pandemic. at the beijing winter olympics, heavy snow has disrupted the skiing schedules. the heavy snow—fall came after a week of criticism of the dry conditions, which saw more than one million metric tonnes of fake snow being produced for the various events. 27 skiers were scheduled to take part in the slopestyle qualifiers, now postponed to monday. among them is home favourite eileen gu, who picked up the big air gold

medal on tuesday. plenty more coming up on the sport and all of the olympics. you're watching bbc news. at least 13 people have been injured after a floor collapsed at a pub in east london. firefighters rescued seven people who became trapped in the bar in hackney. tolu adeoye reports. the first thing wasn't what we saw, but what we heard. suddenly there was this earthquake—like rumble. it was a casual saturday drink that took a frightening turn. hal was on the mezzanine level of the two more years bar in hackney wick when the floor suddenly gave way. 0bviously everyone began to scream and we all started to sink, and quite fast. i was lucky. but those people beneath me weren't so lucky and they were obviously quite scared, and those were the ones who were injured. firefighters rescued seven people who were trapped. 13 were injured in total —

three seriously. the london ambulance service said the collapse was treated as a major incident. from the outside, you can't really tell that anything has happened inside the building. we've not seen any activity while we've been here. i did speak to one local business owner who said it was very lucky the time of day it happened, just before five, because if it had been later into the evening, into the night, this venue gets incredibly busy. tower hamlets council says a structural engineer has been on site to assess the integrity of the privately—owned building. it was due for demolition in two years. when we initially heard we were very concerned that there might be serious casualties. it must have been extraordinarily scary for people in there. we need to get our building investigators to find out what went wrong and make sure people are safe in this really lively part of east london. a statement on two more years' instagram account said it was thankful no one had sustained critical injuries, and its thoughts were with everyone affected. a sentiment echoed by london's mayor, sadiq khan,

who also thanked the emergency services for their swift action. tolu adeoye, bbc london. two nhs hospital trusts are working with police, after a doctor from the west midlands was arrested on suspicion of sexual assault. the sunday times reports that staffordshire police are working with the nhs on a major incident review of the doctor's work at hospitals across the midlands. the force says the 34—year—old man was arrested in december and released on bail. the prime minister of pakistan, imran khan, has warned that lynchings will be dealt with the "full severity of the law" after a man accused of blasphemy was beaten to death. the man was killed on saturday after accusations of desecrating the islamic holy book, quran. it comes two months after another incident in which a sri lankan man accused of blasphemy was killed in pakistan, sparking protests. 0ur south asia editor anbarasan ethirajan has more on the latest incident. there were hundreds of people, according to local media reports, in the district of khanewal,

and there was an announcement that one particular individual that desecrated the holy koran, he set fire to some pages, that was the accusation, but his family said that he was having mental health issues, and despite — he was pleading innocent — this group was trying to target him, and then the local police had arrived at the scene and they were trying to arrest, because desecrating the koran or any insult to islam is a crime in pakistan, so they arrested him, but then because the crowd was really calling for his release and they wanted to take him away, and the local media report said the crowd simply snatched him by force from the police and then beat him to death with stones, and that is why the pakistani officials are now calling for an inquiry to find out whether there was any dereliction of duty by the local police officers. a public inquiry into the wrongful convictions of hundreds of post office branch managers begins tomorrow.

more than 700 sub—postmasters were wrongly accused of theft, fraud, and false accountingdue to a flaw in the computer system they were using. ahead of the inquiry, the sub—postmaster thought to have been given the longest prison sentence has been talking to our business correspondent, colletta smith. harjinder butoy ran a post office with his wife in nottinghamshire, but he's spent the last 1a years fighting to clear his name. charged with stealing £208,000, he was sentenced to three years and three months in prison for a crime he didn't commit. they found me guilty on ten counts out of the 11. that's when everything just... like you're hearing voices in the background while the charges are being read. it was horrible. were your family there in court? sorry... yeah.

i can still hear it from this day, that cell door slamming behind me. with three children under ten, her husband sent to prison, her own news agency business in ruins, balbinder has suffered just as much. it destroyed me. me, the kids. i had nobody. for years, the butoys have been told by the post office that there wasn't a problem with the accounting system. but there was — a big problem. and that's what this public inquiry is supposed to get to the bottom of. who in the post office knew? and why did they continue to blame and prosecute sub—postmasters? the company who sold the software to the post office was fujitsu. jez thompson used to work for them, training sub—postmasters on the new computer system as it was rolled out nationwide. when we did start to get towards, you know, the real meat end of the training,

when we were teaching them how to do the closing of accounts at the end of the month, then we did find and discover a few faults. we could never reckon up everything to be exact. more often than not, it was wrong, yeah. and those reports were always passed up through our managers to fujitsu services and i would imagine to the post office, saying there is still a fault on the live system. the post office have again said they are sorry and that their first priority is providing full, fair and final compensation, but that's not what harjinder wants. i want somebody on the other side to be charged and jailed like i was. they are the ones who signed the final paperwork off. they are the ones who knew if there were any faults on the system or not. you were fighting this for 1h years. does it still feel like you are fighting this? yeah. yeah, it does to me. harjinder butoy ending that report there by colletta smith. the headlines on bbc news... in a phone call with ukraine's

leader, president biden says he'll respond "swiftly and decisively" if russia invades the country. 13 people are injured after a mezzanine floor collapses at a pub in east london. and people in switzerland have voted in favour of tightening the country's tobacco laws by banning virtually all advertising of tobacco products. more now on the news that the us president, joe biden, and his ukrainian counterpart volodymyr zelensky, have agreed on the need to pursue what they called "diplomacy and deterrence" in response to russia's military build—up. i've been speaking to 0lga 0lnuch, associate professor in politics at university of manchester, and associate of the harvard ukrainian research institute. it's very welcome that ukraine's allies are supporting it in this crisis, but certainly this is the time now for not only laying out the extremely serious sanctions that will be going ahead, but also potentially starting to act

on some of these actions already. so, there is a question whether it should be nord stream ii on the table or not. quite frankly, if russia were to invade ukrainian territory, it would have control over the gas pipelines in ukraine, and therefore nord stream ii would no longer be such a good playing chip. we know that sanctions have not worked on the fast. do you think that those we not outline so far would work? they would be enough of a deterrent? i think very strong sanctions are on the table now, much stronger than what we saw in 2014. and i have said this several times in my analytical work. what is clear is that the european union, europe as a whole, nato, is united and very vocal and clear about the nature of the sanctions, and particularly also focusing on putin's inner circle, the kremlin inner circle.

they will in fact be affected by these sanctions. sadly, so will the russian population, but this is the only way to get britain to listen, then it must do what it must. —— then nato must do what it must. president zelenskiy has said today that all of this information and rhetoric coming from world leaders is causing panic in the country. when you speak to people there, are they panicking? no, people are not panicking. i think the ukrainian people, for a very long time, have gone through incredible hardships, including over the last eight years of conflict with russian aggression at their doorstep. this is very personal for them. —— personalfor —— personal for me. i think sometimes when you see ukrainian experts on television, what our uk viewers might not understand that this is my... these are my close friends, my family that i'm speaking about when i tell you this. and whilst they're not packing,

they are making plans. they are under extreme, extreme psychological stress. they make jokes that they're stocking up on medical supplies and our go—to basic foods, but they are very mindful that, should had an invasion occurr, they will need to make plans, and they are very much worried about their elderly relatives that are immobile. —— occui’. and that will not have the option to flee. and of course, many ukrainiansjust don't have the money to pick up and go like someone might do in western europe. in terms of a negotiated outcome, russia wants assurances that ukraine won't be allowed to join nato. given that it won't be in a position to meet the criteria within the next decade or two, could the west agree to that in the short term at least? i think nato has a very clear set

of vouchers, and so does the eu, and certainly so do each of these member states individually, and the united kingdom specifically. i think in these societies, we value the right of ordinary citizens to be able to make decisions about the policy orientations of the country — specifically in the united kingdom, the brits were able to make such a decision not so long ago. you may agree with a decision that was made, but this was in fact a decision that ordinary britons were allowed to make, and it should be ukrainians and ukrainian politicians that are allowed to make the decision for themselves. if they are serious, they will listen to the ukrainians. -- if —— if europe is serious. -- if europe is serious. we've just -- if europe is serious. we've 'ust heard that — -- if europe is serious. we've 'ust heard that the fi -- if europe is serious. we've 'ust heard that the ukrainian �* -- if europe is serious. we've justj heard that the ukrainian president invited joe biden to visit ukraine. we'll bring you more on that as we get it. thousands of people have flocked to venice to celebrate carnival, for the first time in two years.

the event usually draws tourists from around the world, but it was curtailed in 2020 because of covid and cancelled the following year. courtney bembridge has this report. after two years of covid—19 cancellations, carnival is back in venice. translation: this is the carnival of hope. l covid is ending, and we hope to return to our normal lives with hope and enthusiasm. i believe that venice is based on art, and therefore, it has to start again with art and so we try to make art among people. many have made a great effort, but it is a scaled—back affair this year — a hybrid of virtual and in—person events and no big parades. translation: unfortunately, because of the pandemic, - there are few people here, but we are here. we are the carnival. we don't need a big organisation. just come here and have fun — it's beautiful. i hope that in the next few days,

there will be more masks around. i'm glad that there are so many people, but i would like to see a greater carnival atmosphere. it's estimated 50,000 people visited the city on saturday to mark the start of the celebrations. translation: | came here i with my whole family in masks to celebrate the carnival with all the venetians. good people who have also had great difficulties. today, we must have fun and that is all. italy has just eased the coronavirus rules mandating mask—wearing outside, but these revellers were all too happy to have their masks on. courtney bembridge, bbc news. i bet it will be a lot of fun. for most of us, a trip to the seaside can be a fun day out — but have you ever thought about owning your own little slice

of the british coastline? well, if you've got a spare 40,000 pounds — now you can. the stretch of sand at ingoldmells in lincolnshire is one ofjust a handful of private beaches across the uk — and it's up for sale. simon spark reports. # if you're fond of sand dunes and salty air... if you are fond of sand dunes and salty air, we mayjust have the perfect thing for you. i mean, we can't offer you paradise, but we can offer you a slice of lincolnshire's finest coastline. 800 metres of it behind me is up for sale in 100—metre widths, and it comes with what you'd expect — sand, sand dunes and sea. it's being sold by simon adderley, and he's already had a whirlwind of offers. i've had over 1,000 e—mails in five days. we've had over 700 people express a proper interest, and over 200 people make an offer,

so. ..crazy few days. just crazy. he's selling because it's simply time to move on, but despite the huge numbers of interest, he's determined not to sell it to just anyone. the lots are £40,000 each. i have allocated for two individuals. we're basically selling them to people that have got a real affinity with the nature and the love of the coast. one of the gentlemen was a guy who runs a special needs centre and he wants to be able to bring people with special needs to his own piece of beach and to study the ecology and to see it grow. and another was from a teacher who lost her husband and they left two children, and the two children want to buy a piece because he was a geography teacher, and so it's stories like that that i know they're the right people — custodians, not buyers, really.

with today's bright blue sky and winter conditions, it was easy to get lost in the idea of your own personal beach, but not everyone was convinced. no, i don't think... no, to be honest... give me a chalet... if you were selling a chalet off, then, yeah, if there were a chalet next to it! but if you do share simon's principles around nature and pretty much leaving it as it is, you could still be in with a chance. simon spark, bbc news. it does look pretty nice, doesn't it? it's the biggest day of the year for american football fans — super bowl 56 — or lvi, as it styles itself in roman numerals — will take place in los angeles in just a few hours' time. with a crowd of more than 70,000 in the stadium — and hundreds of millions watching around the world — the adverts and the famous half—time show are almost as important as the game itself.

sophie long reports from la. the first super bowl was played in los angeles in 1967. now football's coming home — to a brand—new stadium which just happens to be the most expensive sporting venue on the planet. a spectacular backdrop for the grand finale of this quintessential american sport. it's unbelievable. as soon as the kick—off happens, you just feel like you're almost in a movie, you know? no—one can believe... the tickets, by the way, are like $7,000. itjust feels like you're in the most exclusive nightclub in the history of the world. and you'll see the most famous people in the world sitting in the upper deck. with ticket prices like that, of course, not everyone can go. we are super excited to be going to the game on sunday. and how do they feel that you are going to get to go and you're not taking them? it's so unfair! so there's some conflict at home, but we have told them that the super bowl is not for them, but that we're definitely going to take them to another game next season.

catherine? with an audience that could exceed 100 million, super bowl commercials are huge star—studded affairs, with 30—second slots selling for millions. watch the coffee. and then, of course, there is the half—time show. # in the city... you got snoop dogg, maryj, dr dre, eminem, and kendrick lamar. it doesn't get any better than that. # guess who's back? i've been keeping it all the way real. i'm not trying to be egotistical or anything like that, but who else could do this show here in la? mm—hm. no—one. that's a fact. who else could perform the half—time show other than these amazing artists that we have put together for this thing? but the spectacular is taking place in a city with rising crime and a homelessness crisis. many encampments have been cleared, leading to claims that some

of the thousands living on the streets are being shoved into the shadows. this is a sense of community for them, and it may be hard for those of us that are housed to think through that, but there is a hierarchy, there are belongings. so when they're asked to move and they're forced out of that community, even if it is on the street, it creates additional trauma. whatever the costs, and the amount of money changing hands is monumental, la and its legendary rap royalty are ready. it's super bowl showtime. sophie long, bbc news, los angeles. looks fabulous as ever, doesn't it? now, imagine opening your post and finding a cheque for £2 trillion. well, dozens of people in northumberland and north yorkshire have been in exactly that startling position — but why? megan paterson has been finding out.

2,324,252,000,8001. gareth hughes was expecting compensation for four days without power. but not that much. hundreds of thousands of people in northern england lost connection during storm arwen — many still wait for compensation. a technical errorfrom northern powergrid has given some customers brief thoughts of a luxury lifestyle. we were just on our way out when i picked the post up, so i opened it, laughed, showed my wife, she laughed at it as well. it's such a big value, to be honest. it's something that i can't even really imagine. it would be nice to be able to invest in some of my interests. i'm a featherstone rovers fan, i'm sure they'd appreciate a few pounds towards building the squad to super league. gareth, who's an accountant, shared his surprise windfall on twitter, asking the company, "can you really afford this?" in a statement, northern powergrid told us gareth is among 74 people who have been affected by this error. they've apologised for the mistake. they say they hope to send out the correct compensation cheques

tomorrow, and they thanked customers for being honest about the problem. gareth is reassured his compensation is on the way, but knows it will be substantially less generous than the original cheque. megan paterson, bbc news, hebden bridge. that's one big check. now it's time for a look at the weather with ben rich. hello. wind and rain feature heavily in the forecast for the next few days, following on from what has been an exceptionally soggy sunday. this is where we saw the rain. most parts of the uk had some some very wet weather, aside from northern scotland, where it stayed predominantly dry. and that rain is set to linger across the south—east of england through tonight. more rain feeding back across scotland, northern ireland, then pushing south—eastwards into north—west and wales. it'll be quite windy at around northern coasts particularly. temperatures overnight generally holding above the freezing, given the strength of the wind. tomorrow, quite a messy weather story. this band of cloud will bring patchy rain southwards across england and wales.

scotland and northern ireland i think ending up with a day of sunny spells and showers, some of the showers wintry over high ground in scotland. it will stay quite blustery. temperatures north to south 6—10 celsius, but as we head into the middle part of the week, well, it will turn very mild for a time, and then potentially stormy from mid—week onwards. it is worth staying in touch with the forecast. hello, this is bbc news. the headlines: in a phone call with ukraine's leader, joe biden says he'll respond the us president has been invited to visit kyiv in "coming days". more than a dozen countries tell their citizens to leave ukraine — over 100,000 russian troops remain at the border. 13 people are injured after a mezzanine floor collapses at a pub in east london. police have cleared the remaining protesters blocking a key bridge between canada

and the united states, after a week of disruption.
