president putin's team says the images of atrocities in ukraine are staged — and denies that any war crimes have been committed. also this hour... elon musk floats the idea of changes at twitter — nearly a million people back the idea of an edit button for tweets. and how students in england are looking for new ways to stop devastating flooding, through the power of video games. good morning. moscow's denials to accusations that its forces tortured and killed civilians in the ukrainian town of bucha have been undermined by newly released satellite images which appear to show bodies lying in the streets before russian troops withdrew.

moscow says ukraine has fabricated evidence with the help of western nations. ukraine's president zelensky has accused the russian forces of committing genocide and is expected to address the un security council on tuesday. president biden called vladimir putin a war criminal — saying the russian leader should be put on trial. our correspondent yogita limaye was one of the journalists who travelled to bucha with president zelensky and a warning her report contains some distressing images. the place where ukraine's pushback against russia is most clearly visible. this street in the town of bucha, just outside of kyiv, lined with blown—up tanks and armoured vehicles. today, ukraine's president, volodymyr zelensky, visited the town, drawing attention to the brutality that unfolded here.

"i believe these are definitely war crimes, i believe it's genocide in its purest sense, because children have been killed, women have been raped and civilians executed," he said. through the day, we saw evidence of deliberate murders. in the village of motyzhyn, a shallow grave was found in the woods. four bodies could be seen half—buried, but officials told us there could be more. 51—year—old olha sukhenko, her husband igor and her son oleksander, who was 25. she was the head of the village. they lived in this house. officials believe they were killed by russian soldiers for helping ukraine's army. in bucha, in the basement of a building, we saw the bodies of five men, hands tied behind their backs,

some shot in the head, others in the chest. pictures too ghastly to show. vlad was helping gather the bodies being found. translation: people have been shot in the head by russian - snipers, people on bicycles, people delivering potatoes. i can tell you so many stories, but i don't want to. i want to forget them. these men are still to be identified. the mayor says more than 300 have been killed. they are still discovering dead bodies here in bucha, the horror of what unfolded coming to light now. but there are still areas of this country under russian control, and no—one quite knows what's going on there. "is it still possible to talk peace with russia?",

we asked president zelensky. "ukraine deserves peace, we can't live with war. "every day our army is fighting, but we don't want the lives of millions to be lost," he said. "that's why dialogue is necessary." yogita limaye, bbc news, bucha. our north america correspondent, peter bowes has more details on president biden�*s comments about the russian leader and the atrocities. this is significant because it tells us that there is a process underway with the support of the us president, a process that could lead to a war crimes trial with president putin as the defendant. president biden describing what's happened in bucha as outrageous but stopping short of describing it as genocide, a term which president zelensky has used. but president biden saying he's not prepared to go that far yet

because there's an evidence gathering process that needs to go ahead. the state department here in the us and allies in the west gathering evidence as to what's actually happened on the ground. jake sullivan, the national security adviser here, gave a little bit more detail. he said that the us hadn't yet seen what he described as systemic deprivation of human life that would support genocide. but the key word there is "yet" — the process is underway to gather that evidence that could possibly be used against president putin by prosecutors. moscow's ambassador to the un says russia will present what he called "factual evidence" to the un security council demonstrating that western statements on events at bucha are lies, that the shocking images of bodies in the streets of bucha were staged. foreign minister sergei lavrov has led the kremlin�*s response to the fury of the international community as our russia editor

steve rosenberg reports. this is how russia wants its soldiers in ukraine to be seen — as heroes and humanitarian workers, a caring, sharing army, spreading goodness and light to those it claims to be liberating. but moscow knows the international community doesn't believe that. mr lavrov, the us president has called your president a war criminal and said he must be held accountable. what does that tell us about russia's international reputation right now? translation: what this says is many american politicians | who started the iraq war, destroyed syria, invaded libya. their conscience is in a bad way. our main interest is what the russian people think about this situation. as for evidence of apparent russian atrocities,

the kremlin calls those provocations and fakes. whenever russia is accused of anything, be it the poisonings in salisbury or, in this case, atrocities in ukraine, the reaction from the authorities is much the same — deny everything and point the finger back. because the kremlin has total control of the media here, it's able to persuade many russians that it's right. and the kremlin is receiving spiritual support. yesterday, the russian patriarch led prayers in the cathedral of the russian armed forces. he told soldiers they were heroes defending the motherland and russia's freedom. from the church, no hint of criticism of methods or aims. but some russians disagree with both.

ruslan dostavolov was a senior manager at one of russia's largest banks, but he's resigned in protest at russia's offensive in ukraine and the bank's support for it. translation: russia has created a huge area of chaos _ and lawlessness in ukraine. of course, the russian government is responsible for what's happening there. before the war, i was proud of being russian. there was lots to be proud of, but the war has cancelled all of that out. ruslan took a moral stand, but he has no illusions. the russia he thought he knew has gone. steve rosenberg, bbc news, moscow. let s get some of the day s other news north korea has warned that it would strike south korea with nuclear weapons if the south were to attack. it's the second warning by kimjong—un�*s high—ranking sister, kim yo—jong, in as many days. it comes after south korea s defence minister said

team performance. these games where we perform it well, but we didn't take our chances, we didn't score that goals. but today from the start, we started really well. we put them under pressure. we managed to score, that first goal will give us even more confidence. and we managed to win the game and we didn't concede a goal. so it was a really good team performance. the european champions league returns on tuesday with four mouthwatering ties in prospects on tuesday. liverpool go to benfica, while manchester city, on the hunt for their first champions league title, host atletico madrid in the first leg. manager pep guardiola has been criticised in the past for overthinking his tactics in big games such as not playing a defensive midfielder in last year's champions league final defeat to chelsea. that said, guardiola might have a surprise in store for tuesday's tie. i overthink a lot. and is that fair? absolutely. that's why i had very good

results in champions league. i love will be boring myjob. you have all the time to see the same way against opponents. they face different ways to play. tonight, i take an inspiration and i'm going to do an incredible tactics tomorrow. so we play with 12 tomorrow. this really is the story that has the golf world talking — the potential comeback of tiger woods at this week's masters. woods is a five—time winner at augusta, including that incredible victory back in 2019, but suffered serious leg injuries in a car crash 1a months ago and hasn't played since. the fact he's back practising on the famous course has thrilled and tantalised fans into believing he could feature. woods himself says he'll make a game time decision. the rest of the golfing world is pleased to have him back. very, very excited to have him back. creates a lot of hype and whatnot and shoot from the driving range. we could hear the loud roar when he came out of the clubhouse after

that first tee. that was pretty special to see or to hear at least, and couldn't be more happy for him in the place he's at right now. coming back. in cricket, the former england men's head coach trevor bayliss will take charge of london spirit men's team in the hundred following the sudden death of shane warne last month. warne was coach of the lord's based men's side during last season's first edition of the competition. bayliss will take on the role on an interim basis. the men's hundred draft was postponed until tuesday following warne's passing at the age of 52. that's all the time we've got left now. from me, mark edwards, and the rest of the sports team, bye—bye. over the last decade there've been serious problems with flooding all across the uk. now a pilot scheme has been set—up in northern england to try and tackle the issue by raising awareness and finding solutions in an unlikely way. steffan powell reports. boxing day 2015 in lancashire —

roads turned to rivers, a reminder of the power and devastation of flooding. how to stop it from happening again is a question people have been asking ever since. today in preston, the next generation is looking for an answer somewhere new — in a video game. what i'm looking for you all to do today is to defend preston from flooding for me, please. parts of the city under threat from rising river levels have been carefully recreated in one of the most popular titles in the world, minecraft. we've set up a simulation that will test to see if your barrier will work or doesn't work. so is everybody up to the challenge? working with specialist teachers who use video games in class, the environment agency is hoping that, thanks to the power of play, these pupils will better understand why their local community floods and what can be done about it. it's more interactive and people can understand it more. and it's, like,

really fun to do. it's like we get to actually- learn whilst playing something that will make us understand how to do it and how to help| the world with climate. it's streets like this one in preston that the kids at archbishop temple school have been saving — virtually — from the dangers of flooding all morning. and if this pilot project is deemed a success, then other streets, towns and cities across england could soon be having a minecraft makeover as well. i'm just an old git. you know, if i turn up as a middle—aged man talking about this stuff, they're probably not going to listen to me — or if they are, they might take a little bit of it. but when you put what we are talking about into a context they like, it is fun, things that they know and are aware of and are comfortable with, their interest gets sparked and they come alive. interest gets sparked and they come alive-— interest gets sparked and they come alive. , ., , , come alive. some people will be lookin: at come alive. some people will be looking at this _ come alive. some people will be

looking at this and _ come alive. some people will be looking at this and thinking - looking at this and thinking the environment agency has a big job on its land, lots of pressing issues, why are you wasting time focusing on a video game instead of sorting out the other issues? flour video game instead of sorting out the other issues? our work is more than — out the other issues? our work is more than about _ out the other issues? our work is more than about building - is more than about building walls, it's making places pop the degree of flood risk will we face is going to get worse so we need to boost awareness and understanding of that and their part in helping us respond to that as a nation. learning to save these streets from flooding is the challenge today, but some think that, tomorrow, gaming could be the answer when it comes to tackling a whole host of big subjects. young people do find it immersive. teachers are becoming more comfortable with using games to address a topic or to introduce a topic or to allow a 3d model of a topic to be explored, to bring it to life. back at school, and there's only one question left to answer — is the city safe? together, we were able to practically save preston — on minecraft, at least! so, yeah! steffan powell, bbc news.

some clever ideas and we have all the business needs next. hello, there. it was a mild start to the week, but it will get colder again later on. 16 celsius, though, on monday in hampshire — and for much of the country, temperatures are still in double figures early on tuesday morning. but it is colder in northern scotland — that's where the colder air is. much of the uk in this block of milder air. and between those two different masses, we have this weather front, and that's where we've got focus of the wettest weather. still could be some rain to clear away from england and wales first thing. it may brighten up for a while in northern ireland, most of the weather action is again in scotland — this is where it's going to be wettest, for many, it's rain, but the wetter weather is moving into the colder air, so there could be some sleet and snow in highland and grampian. temperatures only three celsius in aberdeen, but 11 celsius in the central

belt of scotland. could be some more rain coming back into northern ireland later in the day, but some brighter skies, a bit more sunshine on offer for england and wales, and temperatures are back up to 15 celsius. this area of low pressure is sliding these weather fronts across the uk — that one there will push away all that milder air, and it'll be followed by some sunshine, but also some bands of blustery showers on some stronger winds. we still have that wetter weather in the far north of scotland, and snow is more likely in the northern highlands — that's where we've got the coldest of the year — and temperatures won't be quite as high across the uk on wednesday. but that cold air that we've got in northern scotland is going to come south on thursday, with a northerly wind accompanying that, really dropping the temperatures. now there's still some rain threatening to run through the english channel — again, it's taking a more southerly track, so it's moving away. essentially, we'll have some sunshine and wintry showers, the bulk of those in northern ireland, northern england, and particularly into scotland. and temperatures will be around

nine celsius in the afternoon. now there's still a lot of uncertainty about this rain coming in from the atlantic running through the english channel on friday. could be into southern parts of england and wales. into the cold air, there may be some sleet and snow over the hills for a while before that pulls away. but for the most part, it's that northerly, chilly air that we maintain with some sunshine, and again, some more wintry showers. temperatures only around eight celsius, and we'll find some frost returning at night.
