welcome to our viewers on pbs in america and around the globe. they are images that have shocked the world — the pictures of dead civilians lying in the streets of the ukrainian town of bucha have led to worldwide condemnation of russia. 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. as russian troops withdraw from bucha — which is just to the north—west of the capital kyiv — the extent of the brutality is becoming ever more clear. russia is still denying any

involvement in the mutilation and murder of hundreds of civilians. it says the images shown by the world's media are staged and fake. our correspondent yogita limaye was one of the journalists who travelled to bucha with president zelensky and i want to warn you, 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, ukrainian�*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. 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. and 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 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. pakistan's supreme court is expected to decide on tuesday the fate of embattled prime minister imran khan. on sunday, members of his party blocked a vote of no—confidence in the pm and dissolved parliament. furious opposition politicians have now asked the supreme court whether that was constitutional. a covid lockdown continues in china's biggest city, shanghai, where the international expo center has been turned into a quarantine zone. health officials have defended a policy that separates children who have tested positive from parents and other carers who are negative. outrage has spread after photos appeared on chinese social media, appearing to show crying infants left alone at a quarantine centre. south africa's national

state of disaster — which has been in place for more than two years in response to covid—i9 — has ended. all regulations made under the state of disaster have been repealed — aside from a few transitional measures such as mask wearing indoors. leading international scientists have warned that it's �*now or never�* if disastrous climate change is to be minimised. the latest assessment from the united nations inter—governmental panel on climate change says the rise in global temperatures can only be held below one—and—a half degrees celsius — the real danger mark — if governments act immediately. our climate editor justin rowlatt reports. what the un has published today is a road map for saving the world from the worst of climate change, but it comes with a massive warning. it is now or never. there can be no more

broken promises on climate, says the un. some governments and business leaders are saying one thing but doing another. simply put, they are lying. and the results will be catastrophic. but there is some good news in today's report, so let's start there. the cost of renewable technologies — wind turbines, solar panels, batteries — have been falling far quicker than anyone expected. as a result, the world is rapidly building solar and wind plants. in fact, last year, 10% of global electricity was generated from renewables, according to a report last week. but, says the un, harnessing the power of the sun and the wind will not be enough. the report details how we'll also need to change the way we get around, what we eat, how efficient our homes and businesses are, how we farm, how we produce the goods we buy, how we move those goods around and how we protect the natural world. in short, pretty much everything has to change,

because pretty much everything we do produces carbon dioxide. it is possible, says today's report, but time is almost out. we've got to peak carbon emissions before 2025, says the un, and then cut them back by at least 43% by the end of 2030. and then we need to take them all the way down to net zero by 2050. it is a tall order, especially given that emissions are currently going up, not down. what needs to happen is that we need to use all the available tools we have, in terms of policies, technologies, and we need to start to use them immediately. if that happens, then it is still possible, just possible, to limit warming to 1.5 degrees. but we'll also need to develop technologies to take carbon out of the atmosphere to balance

out those emissions we cannot eradicate. trees are one way, but we'll need high—tech solutions too, and they have yet to be proved, at scale. now, making all these changes will cost money, but it will also deliver huge benefits, says the un. your life will probably get better. that is one of the key results, because there are many benefits with these measures that are needed — better air quality, better health, more active lifestyles, healthier food systems. the authors of today's report are very clear. they say that the fossil fuel era has to end, and end very soon. that conclusion, indeed all the conclusions in this report, have been approved by all of the governments of the world. so the big question now is, will they enable the radical action today's report demands?

i'm joined now by leah stokes, an assistant professor of climate politics at the university of california, santa barbara. iam i am interested to know from you if you agree with un scientists that, if governments around the world follow this plan that they have an ounce, we can limit the effects of climate change. we can limit the effects of climate chance. ~ ,,., , climate change. absolutely. the re ort climate change. absolutely. the report was _ climate change. absolutely. the report was clear _ climate change. absolutely. the report was clear that _ report was clear that governments around the world have to take action today. time is of the essence because we had to be peaking carbon pollution in the coming years and cutting it by about half by 2030. the good is that we have the technologies we need and increasingly they are cheaper and cleaner than dirty fossil fuels. those technologies include wind and solar, electric vehicles, electric bikes, heat pumps, heat and cool bikes, heat pumps, heat and cool, you name it. there are lots of great solutions that we have but governments will need to invest in bailing them out now. other governments around the world pulling the wool over our eyes? 0p

the world pulling the wool over our eyes? op 26, we are going to cut carbon emissions, they just taking us for a ride if technology is there and this plan is doable, why didn't they adopt a plan like this? governments are consistently failing to act on one thing the report said drawing on science research by people like myself and others is that is because fossil fuel companies have and others is that is because fossilfuel companies have been fossil fuel companies have been lobbying fossilfuel companies have been lobbying governments around the world to slow down the energy transition. they have done this quite famously by spreading misinformation, by saying that climate change is not real and lying to people all around the planet and so governments really need to start doing the bidding of everyday people and keep our livable planet and stopped doing the bidding of fossilfuel stopped doing the bidding of fossil fuel corporations. d0 fossil fuel corporations. do ou fossil fuel corporations. do you think _ fossil fuel corporations. do you think world leaders get it? to think they understand how serious this is?— serious this is? many world leaders do. _ serious this is? many world leaders do. not _ serious this is? many world leaders do. not everyone, | serious this is? many world i leaders do. not everyone, of course. we need legislator, democratically elected governments around the world to act. right now in the united

states there is a bill before the united states senate that includes $555 billion in clean energy investment and all the democratic senators have said they are willing to do that so what we need to have happen in the coming months is for that to pass the senate and similarly, governments in europe and all around the world need to be investing in clean energy and climate action now. just before the tail is, there are machines that can suck carbon dioxide out of the air, the bad carbon dioxide, isn't there? and mechanical trees. i've seen them. there? and mechanicaltrees. i've seen them.— there? and mechanicaltrees. i've seen them. yes. so we are already at — i've seen them. yes. so we are already at dangerous _ i've seen them. yes. so we are already at dangerous levels - i've seen them. yes. so we are already at dangerous levels ofl already at dangerous levels of carbon dioxide. we are about 415 ppm and historically, humans lived at 350 ppm. however, these machines cannot pull it fast enough so the number one thing that we have to do is start putting more into the atmosphere which means we have to get off fossil

fuels. we have to stop burning fossil fuels.— fossil fuels. are very depressing - fossil fuels. are very depressing but - fossil fuels. are very| depressing but thank fossil fuels. are very - depressing but thank you very much. fascinating as well. do stay with bbc news. still to come: we will tell you about the new home of surfing and one clue, it is not in california or australia. 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 world news, the latest headlines. ukraine's president zelensky visits the battered town of bucha — and accuses russian forces of committing genocide. the world's richest man has snapped up nearly 10% of twitter�*s shares, paying almost three billion dollars. with me is our reporter stephanie prentice. thank you forjoining us. so

this makes elon musk one of the most, if not the most powerful person at the company, surely? is gone from being a prolific user to its biggest stakeholder so now he has around 9.2% stake in the company. that is for points more than the person is started it and one of the reasons people are interested is because of recent comments he has been making about whether twitter adheres to free—speech policies. he has been asking his followers, should i start my own social media platform. all of that somewhat begs the question, instead of starting his own platform is he going to try and change one from the inside with a sort of, if you can't beat them join them attitude. so what we need to look at now is whether he will, the other points we need to look at our whether twitter would ever be able to edit him and ban him regardless of what he may tweet going forward that up now, we know it is the past few minutes he has been calling for an edit button the platform. i

he has been calling for an edit button the platform.— button the platform. i would love one- — button the platform. i would love one. bring _ button the platform. i would love one. bring it _ button the platform. i would love one. bring it on. - button the platform. i would love one. bring it on. let's l love one. bring it on. let's take a quick _ love one. bring it on. let's take a quick look - love one. bring it on. let's take a quick look at - love one. bring it on. let's take a quick look at one i love one. bring it on. let's take a quick look at one of| love one. bring it on. let's i take a quick look at one of his most recent tweets. he wrote: so seemingly he is keeping it quite simple so far.— quite simple so far. what effect do _ quite simple so far. what effect do you _ quite simple so far. what effect do you think - quite simple so far. what effect do you think this i effect do you think this purchase will have on the company and the future of the company and the future of the company as well? it has been a bit shaky recently. the company as well? it has been a bit shaky recently.— bit shaky recently. the share rice bit shaky recently. the share price immediately _ bit shaky recently. the share price immediately rocketed l bit shaky recently. the share i price immediately rocketed and the value went up by 25% but we also saw quite early on some political murmurings out of the us. senior republicans asking him to make some changes already as well as calls for donald trump to be allowed back on the platform. now, as we know, he was suspended and then kicked off some of his comments over the last us election. earlier we spoke to a republican strategist. let's take a listen to him now. same as what is he going to do? seek as what is he going to do? seek a seat on the board of directors? try to push internally to try to make some

changes? i don't think this was a passive purchase of twitter stock. i think he is going to do what has always done, which is to be an outspoken and a little bit irreverent figure. watch out, twitter. he is the political strategist in the us. when beginning to take away from all of this is according to official documents elon musk is a passive investor in twitter but experts to say that he won't set back for long and do nothing. he won't set back for long and do nothing-— do nothing. thank you for takin: do nothing. thank you for taking us _ do nothing. thank you for taking us through - do nothing. thank you for taking us through that. i to sri lanka now — where hundreds of thousands of people have been protesting against worsening shortages of fuel, food and medicines. the governor of the central bank has resigned and senior government ministers have stepped down because of the growing economic crisis. ( problems have been made worse by the collapse of the tourism industry during the pandemic as our correspondent rajini vaidyanathan reports from colombo. they're calling it sri lanka's arab spring.

a mass uprising in a country on the brink of economic collapse. people have had enough of food and fuel shortages and daily power cuts. a few moments ago, the street lights went. people are waving their phones in the airfor light. this is another moment of solidarity, in a country which was once deeply divided by civil war. as the desperation has grown, so have the protests. why are you here today? to show the disbelief that the people of sri lanka have in this government. and to show how they have failed us as a nation. people can't afford their daily rice, their dhal, their basic necessities. people can't get on buses to come to work, to go to school. how much worse can it get? there is no petrol, there is no diesel. | kids can't sit their exams. because there is no paper. people have been queueing for hours just to get cooking gas. the country struggled to import

basics after foreign currency reserves ran low, in part due to a drop in tourism. prices are now sky—high. at the local market, we met advertising executive rajeev. so this is an apple. it used to cost, what, a year ago? a year ago, 30 rupees. 30 rupees an apple. now, how much are the apples? right now, one piece is 100 rupees, no? 150? so the price of this apple has gone up by five times in a year. sri lankans blame the country's president, gotabaya rajapaksa, for mismanaging the economy. seen as a ruthless politician, he is clinging on to power, even as the entire cabinet quit. tonight, protesters gathered outside his office in the capital, demanding he resign. an island nation in turmoil, running out of the basics and running out of patience. rajini vaidyanathan,

bbc news, colombo. and finally — i want to tell you now about the new home of surfing. no, not malibu in california, not australia's gold coast, but devon in south west england. that's right. devon is now a world surfing reserve — one of only 12 in the world, and the first in the uk. jon kay has the story. ok, so the weather wasn't exactly malibu today. but the mood was ecstatic, in the uk's first world surfing reserve. what do you love about this place? everything. i'm so proud. kevin cook has lived here all his life. he started surfing at the age of six, and hasn't stopped. he's led the campaign for north devon to get special status. it's absolutely massive. we are just so stoked that it's come about in this way.

it's a culmination of about five or six years work, to try and put all this together, so it's amazing. it's the combination of the waves, with the environment, with the culture, and with the economy. it all meets here in north devon to make it such a special place. only one place in the world is awarded this reserve status every year. but now this stretch of coast, which includes croyde, saunton and lynmouth joins the like of santa cruz my dad taught me to surf when i was three. rosie is from a local farming family. but she swapped muddy fields for riding waves, and she's now a surf ininstructor. all of the uk's best surfers, people on the gb squad, they are all from devon, like woollacombe and croyde, so i'm not surprised it's on par with, like, these amazing breaks. feeling proud? yes, really proud. yeah, love it. oh, just to get that

feeling, to get the energy, just, just amazing. lovely place, very friendly people here. just absolutely amazing. just gets you in the soul. it makes you feel like you're - coming home when you come here. with the season just getting started, international recognition could bring even more visitors, and could help protect this coastline for the future. one, two, three... jon kay, bbc news, north devon. just a reminder before we go that for the latest news on ukraine, there's lots on our website — where you can see our live page that's constantly being updated by our teams on the ground and our correspondents, including the latest on how the us is backing an international prosecutors team to head to ukraine to collect that's at bbc.com slash news or download the bbc news app. you can reach me on twitter — i'm @ chris rogers news.

hello there. it was a mild start to the week, but it will get colder again later on. i6 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.

this is bbc news. the headlines... ukraine's president zelensky visits the battered town of bucha — and accuses russian forces of committing genocide. it comes as international condemnation grows of atrocities in ukraine — as shocking images of civilians killed during russia's advance, are seen around the world. russia denies involvement, with president putin's team saying the images of atrocities in ukraine are staged — and that no war crimes have been committed. but president biden has said for the first time that vladimir putin should be put on trial. leading international scientists are warning it's "now or never" if disastrous climate change is to be minimised. the latest assessment from the united nations panel

on climate change says the rise in global temperatures
