welcome to bbc news — i'm chris rogers. our top stories... killing for pleasure. ukraine's president accuses russia of carrying out the worst war crimes since world war ii. under the laws of war, killing civilians and wanton destruction are both crimes unless it can somehow be proved that that was a military target. satellite images show the nearby town of bucha littered with bodies. russia says the pictures are fake — ukraine's president calls for the toughest sanctions. translation: after what the world saw in bucha, i sanctions against russia must be commensurate with

the gravity of the occupiers�* war crimes. and in other news — why some scientists are threatening to down microscopes and go on strike until countries do more to cut global warming. ukrainian president volodymyr zelensky has told the united nations that russia has commited the worst war crimes since world war ii, accusing the country's military of creating mass starvation and raping and murdering civilians. it comes after images emerged from the town of boocha, following the retreat of russian forces, showing bodies of civilians lying in the streets, and mass graves. moscow says the pictures are fake, and that no civilians suffered any kind of violence while russian forces were in control of the area. president zelensky is also warning that the number of dead in kyiv�*s other surrounding towns and villages, like borodyanka,

could be even higher. police there say they believe hundreds of people are buried beneath the rubble of civilian apartment blocks, destroyed by russian shelling, and survivors were prevented from escape. the bbc�*sjeremy bowen has been to borodyanka and sent us this report. the destruction in the centre of borodyanka is the worst for its size i've seen in any of the towns around kyiv, including much fought—over irpin and bucha. the worst killing in borodyanka might have come when these flats were destroyed. a line of them stood here. you can see the gaps. after you. next door to the rubble, dmytro stashevskyi inspected his shop. this is your shop? medical, pharmacy, it's a pharmacy, yeah? destroyed, everything's gone. we went upstairs where his wife

svitlana was trying to clean up his mother's flat. their family is safe, but not their friends in the destroyed building next door. translation: they were all our neighbours. - shortly after the air strike, people nearby heard some voices shouting for help. russian soldiers stopped them digging. they threatened to shoot if they tried. dmytro left 30 others in the cellar before the strike. when he went back in the morning, it was full of rubble. all 30 are missing. you're lucky to be alive, aren't you? "yes," he said, "my wife, mother and daughter were praying for me." this is a civilian block of flats. now, only a ballistic missile or an air strike can do this sort of damage. under the laws of war, killing civilians and wanton destruction are both crimes unless it can somehow be proved that that

was a military target. close by, local people were getting some food organised by their priest, who said he'd seen the russians shooting civilians. you saw civilians being killed by a russian sniper? translation: it was the 2nd of march near the petrol station. i we were driving along, followed by two civilian cars. theyjust shot them. it was an execution. most people here left during the russian occupation. svitlana said coming back made her empty and scared. tell us what the town was like before. eventually, she said, "it was very nice, very green." hundreds of people could be lying dead under the rubble, say the police.

once the heavy lifting gear arrives, they'll know more. jeremy bowen, bbc news, borodyanka. just 25 kilometres from borodyanka — in the town of bucha — ukrainian human rights officials say a mass grave near a church may contain as many as 300 bodies. yogita limaye has this report. destruction and death are expected during a conflict. but what's happened in bucha violates the rules of war and of humanity. irina abramova lived peacefully here with her husband until the 5th of march. then a russian tank pulled up outside. their home was shelled. as it was burning, russian soldiers shouted, calling the couple outside. translation: they wanted | to know where the nazis are.

they said we have an evil government with nazis in it and we should be punished for it. i said, "we're not guilty. we're just humans. " minutes later, her husband 0leg, a ao—year—old welder, was shot in the head. russia saying it's not killed civilians deliberately in ukraine. what do you want to say about that? translation: my husband wasn't a soldier. _ he'd never held a gun. he was a peaceful man. they took him from our home in his slippers, asked him to take his shirt off, made him kneel on the ground and killed him.

she wears 0leg's wedding band around her neck. she says it's all she has left of him now, along with the shirt and sweater he was wearing the day he died. translation: | want. the whole world to know that the russians are killers. they�* re not human. they're killing women, children, civilians. she shows us the spot outside their home where 0leg was killed, bloodstains still visible where his body lay for weeks. translation: he was - the best man in the world. he was kind and caring. he was the love of my life. i could give anything to bring him back. the more you talk to people in bucha, the more you learn of the terror that this town lived through. a local resident told us that a woman riding a bicycle was shot on this street.

in a house down this road, a man was trapped in his basement for weeks without much food. he dared not go anywhere because there was a russian tank standing outside. in the backyard of a church in bucha, the bodies of people who died here continue to pile up in a shallow trench. ukrainian and russian soldiers and ordinary people together in a single grave. more than 300 civilians have been killed here. only a few have so far had the dignity of a proper burial. yogita limaye, bbc news, bucha. in his latest video address to the nation, the ukrainian president, volodymyr zelensky, urged the west to impose the toughest possible financial penalties on russia.

translation: after what the world saw in bucha, i sanctions against russia must be commensurate with the gravity of the occupiers' war crimes. if after that, russian banks will still be able to function as usual, if after that, the transit of goods to russia will continue as usual, if after that, the eu countries will pay for russian energy as usual, then the political fate of some leaders will develop not as usual. my advice to everyone — feel now that the moment is really crucial. in an address to the united nations president zelensky�*s not only accused moscow of war crimes, but he said the un was proving ineffective because russia is abusing its veto as a permanent member on the security council. and that, he said, was preventing international action. here's our north america editor, sarah smith. horrific images of dead civilians lying in the streets of bucha shocked the world, but russia claims the scenes have been staged.

analysis of satellite imagery taken in mid—march shows bodies lying in the precise positions corpses were later found, proving they were killed when russian forces controlled the area. ukrainian president zelensky told the un security council the most terrible war crimes since world war ii are being committed in ukraine, saying what's been revealed in bucha is also happening elsewhere. translation: the massacre in our city of bucha is only i one, unfortunately only one of many examples of what the occupiers have been doing on our land for the past 41 days. there are many more cities, similar places, where the world has yet to learn the full truth. he lambasted the security council for failing to guarantee the security of ukraine and showed an extremely graphic video of dead civilians in several ukrainian towns which visibly shocked the council. we are appalled by what we have

seen and reiterate our solidarity with ukraine. the us wants russia to be removed from the un human rights council in response to human rights abuses in ukraine. reports indicate that russian federal security agents - are confiscating passports and ids, taking away celll phones and separating - families from one another. i do not need to spell out - what these so—called filtration camps are reminiscent of. it's chilling. russia denies that its forces have killed civilians, calling the pictures of dead bodies fake news. translation: during the time that the town was under - the control of russian armed forces, not a single civilian suffered from any kind of violence. that impassioned plea from president zelensky to the un, along with harrowing

accounts coming out of ukraine, are piling pressure on world leaders to respond. further sanctions are expected to be announced tomorrow, and the us has committed to hold the russian leadership accountable for war crimes, but with no explanation as to how or when that might happen. the un needs to act immediately, president zelensky demanded. if it can't do anything beyond talking about the war in ukraine, he told them, then it might as well close down. sarah smith, bbc news, washington. the white house has given more details of new sanctions it will impose against russia on wednesday. it said the us, european union and the g7 group of the most industrialised nations had worked together on the package. they will target russian government officials, their family members, russian owned financial institutions, state—owned enterprises, it is part of a continuation of efforts to put consequences in place and hold russian

officials accountable. let's get more on this from our north america correspondent peter bowes. they will hurt ultimately the russian people but i think it's also hoped that they will hurt those in the higher echelons of russian government and business as well with an immediate impact. there is a huge sense of urgency i think about this latest raft of sanctions that will be announced, a coordinated effort between the european union and the g7 which the white house says represents 50% of the global economy. jen psaki says it is hoped russia will be sent down the road of economic, financial and technical isolation and she talked about the financial institutions, the state—owned enterprises and perhaps most crucially those senior russian government officials and their families. we do not have details of individuals yet but i think we can be sure these will be

far—reaching sanctions, that is, it's hoped, have a quick impact, perhaps a faster impact than some of the sanctions already because it could be argued that clearly though sanctions were imposed to ultimately stop the war the war has not stopped and we are seeing more and more atrocities every day. stay with us on bbc news — still to come... the mummy returns — we'll tell you about the ancient human remains that date back to a time before the incas. 25 years of hatred and rage as theyjump up on the statue. this funeral became a massive demonstration of black power, of power to influence.

today is about the promise of a bright future, a day when we hope a line can be drawn under the bloody past. i think that picasso's i works were beautiful, they were intelligent, and it's a sad loss - to everybody who loves art. this is bbc news, the latest headlines... more evidence of possible war crimes is revealed in ukraine, as the russian retreat from town's around kyiv continues.

president zelensky has alleged russia has committed the worst war crimes since world war ii — russia denies it. every week at this time we take a look at the climate crisis ? bringing you stories with big implications for our planet. this week on climate critical, is the world listening to climate scientists? some say they're not and are threatening to go on strike. it's 3a years since the un set up the international panel on climate change. since then, the world's scientific community has gathered evidence from every corner of the globe, written six increasingly apocalyptic reports, the latest coming out just last monday. and presented their findings to world leaders at 26 summits known as cops. yet in that time, global carbon dioxide emissions have risen by at least 60%, and the world is on track

to warm by 3.2 degrees, nearly double the ipcc target. so was three decades of effort worth it, and what's to show for it? to answer that question let s talk to dr bruce glavovic, professor at new zealand s massey university ? and contributor to the latest ipcc report. he s calling for climate scientists to stop their work until countries do more to cut global warming. and not just world and notjust world leaders, people like me and others watching and notjust world leaders, people like me and others watching as and notjust world leaders, people like me and others watching as well, and notjust world leaders, people like me and others watching as well, is and notjust world leaders, people like me and others watching as well, is that correct?— correct? climate change scientist, _ correct? climate change scientist, mothers, - correct? climate change - scientist, mothers, fathers, we all have responsibilities, yes. the findings of these series of reports are critical, climate

change is interwoven into the infrastructure of people on the planet right now and with dangerous climate change unfolding before our eyes, this predicament gets worse, there is a need for global action now. , , ~ ., is a need for global action now. ,~ , now. this sounds like a stupid auestion now. this sounds like a stupid question but _ now. this sounds like a stupid question but when _ now. this sounds like a stupid question but when people - now. this sounds like a stupid question but when people like yourself say we are not listening, world leaders and the public, you see every friday, millions of children and young people around the world demanding more action. they are listening, they are the future generation and you see world leaders sat on a stage in glasgow saying we are listening, we know the world is in our hands and your hands and they make announcements so when you say we are not listening, what exactly do you mean? it’s what exactly do you mean? it's a ve what exactly do you mean? it�*s a very well—made point you what exactly do you mean? it�*s a very well— made point you have a very well—made point you have highlighted. in fact, the ipcc is a science policy interface and since 1990, when the first assessment report was released, governments have signed off, they have accepted the evidence presented before them, for over

30 years. yet in that time, global greenhouse gas emissions have continued to rise. and so the evidence is really playing before our eyes, despite the governments of the world agreeing that climate change is under way, agreeing that climate change is underway, it agreeing that climate change is under way, it is present right now, it is a present problem, despite that recognition, the actions have not been taken and so really, this hits home to the political leaders who have failed to take the action necessary to stem greenhouse gas emissions. and also, it comes back to us as individuals, our business community, our communities, left, right and centre so yes, we all are responsible for making a shift. to we all are responsible for making a shift.— we all are responsible for making a shift. to be clear, scientists _ making a shift. to be clear, scientists like _ making a shift. to be clear, scientists like yourself - making a shift. to be clear, i

scientists like yourself across 195 countries over three decades, you have made it very, very clear that we are possibly heading to armageddon, we are possibly heading to the end of the world as we know it if things continue as they are, if not enough is being done. so you don't feel like you are being listened to, so why do you think that is? what is the policies of world leaders over three decades to take what you say, believe it but not react in the way that you would like them to? �* , ., in the way that you would like them to? �*, ., , them to? it's not 'ust the climate * them to? it's not 'ust the climate change _ them to? it's notjust the climate change science i climate change science community that is concerned, there are many as you point out around the world. the evidence the scientific community has put before governments and the world is now unequivocal and the reason that the actions have not been taken is because business as usual suits those with political power and influence. it is difficult to change at a systemic level,

those behaviours, those practices, those vested interests that profit from continued consumption and use of fossil fuels that are causing this crisis. so until such time as we are able to bring about change to the structural architecture that means we are addicted to fossil fuels and activities that generate these greenhouse gases, we are condemning ourselves, this generation, children born now, who will be around 80 years old in 2100, by which time they and their children, the future generations, and the nonhuman species we shared a planet with will be living in an apocalyptic world that you just described. apocalyptic world that you 'ust described. , ' . ., apocalyptic world that you 'ust «samefi described. difficult to say and imauine! described. difficult to say and imagine! very _ described. difficult to say and imagine! very briefly, - described. difficult to say and imagine! very briefly, when i imagine! very briefly, when scientists put their tools down and go on strike, what does

that look like and how powerful a message will that be? we are sa in: a message will that be? we are saying more — a message will that be? we are saying more than _ a message will that be? we are saying more than simply - a message will that be? we are saying more than simply put. saying more than simply put your tools down. what we are saying is that climate change scientists and research community that is focused on documenting the problem and not too contributing to solutions, thatis too contributing to solutions, that is the kind of science that is the kind of science that needs to come to a halt. we do not have time left to continue to merely document the problem, we need to focus on working with local communities and to doing the science necessary to restore the science society contract that we do in the public interest so in other words, practically, the seventh assessment of the ipcc, do we have time to wait another six or seven years for yet another report that says yet another report that says yet another report that says yet another set of litany of problems? and another 26 summit

by which time we are in a dangerous world? no, we do not have that time, the ipcc is a relic of the 90s, time for action. ~ , ., , , , action. we must wrap it up but it is fascinating _ action. we must wrap it up but it is fascinating hearing - action. we must wrap it up but it is fascinating hearing from i it is fascinating hearing from you. doctor bruce, thank you. the united nations human rights agency says it's concerned over the measures el salvador has introduced to combat gang violence. suspects can be detained without a warrant, gang members given longer sentences — and president nayib bukele has even threated to deny them food. shelley phelps reports. rounded up, detained and under heavily armed guard, more than 6,000 suspected gang members have been arrested in the ten days since el salvador�*s government declared a state of emergency after a bloody weekend of gang violence that involved almost 90 reported killings. outside a jail in the country's capital, families waiting for news of detained loved ones condemned what they say are unjustified arrests.

translation: it is a great injustice. i in the case of my family, it was my niece who was unjustly taken from her home without an arrest warrant or anything. because supposedly she is the partner of a gang member. translation: we want to remove the president because we can - no longer stand him, what he's doing is too much. if your son gets arrested, how is he not going to hurt you or your wife? won't it hurt you to see her standing here, waiting, enduring the sun? new measures including allowing authorities to detain suspects without a warrant had provoked concern from the un's human rights body. the maximum prison sentence for gang membership has also been increased to 45 years. speaking at a police barracks, el salvador�*s president nayib bukele went further, threatening to deny food

to imprisoned gang members if they tried to take revenge for the crackdown. translation: in total- we have 22,000 gang members who have no mattresses, who sleep on the floor and who are asigned to two meals per day and in such conditions that none of the gang members who are outside want to come in. it is important they know if they try to be clever, they will go from two meals down to zero and we will see how long they last. for decades, el salvador has suffered high levels of violence from criminal gangs and the president pledged to make tackling it a top priority after his election in 2019. his latest comments follow a stark warning last week that gang members face two options — prison or death. shelley phelps, bbc news. archaeologists in peru have unearthed a mummy that could be a thousand years old. the preserved remains date back to before the incan empire.

the discovery — which was made at an archaeological site near lima — has been described as one of the most important finds at both a national and international level. hello. the weather looked very different between the top and tail of the uk on tuesday. across england and wales, the sun came out for many. and in the sunshine, temperatures got up into the low to mid teens. this was the isle of wight tuesday afternoon. here we are, though, in aberdeenshire tuesday afternoon, a very different picture — some fresh snowfall, temperatures barely scratching above freezing. arctic air to the north of the uk. to the south, atlantic air. the two mixing out towards the west, with this occlusion turning back behind an area of low pressure. slightly cooler air flooding in to all parts of the uk on wednesday. relatively milder air, though, just pushing into the far north of scotland. but that big area of low pressure does mean, for all areas, it's going to be windy and there will be some bands of punchy showers marching through.

but we've lost the snow from northern scotland, the cold air really confined to the northern isles, but mostly rain that we'll be seeing here. further south, some good spells of sunshine between the showers, but when the showers push through, they possibly could be accompanied by some hail, thunder and lightning. temperatures down a couple of degrees on tuesday. it was a very mild start to the week. wednesday into thursday, we start to pull colder air in, though, to the north of our area of low pressure once again. and through wednesday evening, but particularly overnight into thursday, the colder air mixes in with our weather fronts. and it looks like we could see some significant snow for northern scotland once again. a risk of ice here for first thing thursday, certainly, and potentially that wintry weather affecting the central belt of scotland through the morning rush hour. we will see the showers thinning out as they sink south through the course of the day, but still the chance of a wintry element across the pennines into thursday afternoon. sunshine for many come thursday afternoon,

but it will feel chillier, especially in contrast to the start of the week. and then cold air right the way across the uk for friday. i think there will be quite a bit of sunshine, some wintry showers in the north and east. biggest question mark — what this area of low pressure deepening to the south of the uk will do. at the moment, it looks like it will slide in to the continent, bringing some very wet and windy weather to northern france. but it also looks like it could bring some very wet weather to the south coast of the uk and be accompanied by strong winds. if it pushes a little further north, there's just the question about whether it will bring something more wintry. stay tuned.
