to hold serious talks with the ukrainian president, volodymyr zelensky, as russia claims to have made strategically significant gains. ukraine has warned it may have to withdraw from severodonetsk, the easternmost city it still controls. it comes as the russian ambassador to the uk told the bbc that moscow will not use tactical nuclear weapons in the battle for ukraine. our world affairs correspondent caroline hawley reports. russian forces in action in eastern ukraine, where they're making advances. moscow says its forces have captured the town of lyman, an important railway hub, and the key city of severodonetsk is now in its sights. translation: if the occupiers think that lyman and _ severodonetsk will be theirs, they are wrong. donbas will be ukrainian. but this is the kind of firepower russia is bringing to bear on the region,

and after three months of war, ukraine wants more help from the west to resist. today, president putin spoke to his french and german counterparts, who urged him to hold direct and serious negotiations with ukraine to end the conflict. remember this moment at the start of the war, when president putin alarmed the world by announcing he'd put russia's nuclear deterrent forces on high alert. russia has the world's biggest nuclear arsenal, and this exercise just before the invasion involved nuclear weapons, but the bbc�*s been told it's unlikely to use them in ukraine. do you believe that there could be the use of a tactical nuclear weapon in the war in ukraine? no. tactical nuclear weapon in accordance with russian military doctrine is not used in conflicts like that at all. so, you do not believe that will happen? i don't think so. can you categorically say it will not happen? we have very strict provision

on the issues of the use of tactical nuclear weapon, and it is mainly when the existence of this state is endangered. it has nothing to do with the current operation. but russia does still want to display its military might to the world. here, a missile is test—fired that president putin says can travel at nine times the speed of sound, its range over 600 miles. the images released today by russia's defence ministry carry a message of the potential reach of its destructive power. caroline hawley, bbc news. president biden has urged americans to "make their voices heard" as he renewed his appeal for tighter gun controls. it follows the massacre at a school in texas, in which 19 children and two teachers died. meanwhile, the former us president, donald trump, and other leading republicans have dismissed calls for gun reform, saying the shooting was a reason to arm — not disarm.

0ur north america correspondent barbara plett usher reports. just days ago, children cowered on the floor in this school as a killer armed with assault rifles stalked their classroom, the latest victims of a uniquely american tragedy. president biden addressed the parents�* heartbreak in a speech at a graduation ceremony. he'll be visiting the town tomorrow. those parents are literally preparing to bury their children. in the united states of america, to bury their children. there's too much violence, too much fear, too much grief. the massacre thrust the issue of gun control back into national focus. gun rights activists said they were horrified by the violence, but the national rifle association went ahead with its convention in texas, supported by its high—profile champion. like others, he insisted the solution had nothing to do with guns. the existence of evil

in our world is not a reason to disarm law—abiding citizens who know how to use their weapon and can protect a lot of people. the existence of evil is one of the very best reasons to arm law—abiding citizens. it's taking our babies! the convention was a target for growing outrage over mass shootings with assault weapons and over the fierce opposition to gun control in the republican party. here in uvalde, people say something has to be done, but they're reluctant to get into the bitter partisan debate over gun restrictions. and they're consumed with the process of grieving, planning funerals now that will start to take place in the coming days. the sorrow here is mixed with anger over mistakes made by the police. this man, ruben mata montemayor, heard the gunshots from a distance. he found out later they'd killed his great—granddaughter. where was the police that's supposed to be there to protect them kids? why, why, why?

there are no answers here. they're beseeching a higher power to help them. barbara plett usher, bbc news, uvalde, texas. the death of a black man, forced into the boot of a police car, where a gas grenade was set off, has sparked outrage in brazil. video footage shows two officers holding down the boot with genivaldo santos inside, as thick smoke poured out of the car. an autopsy confirmed mr santos died of asphyxiation. mark lobel reports. the latest shocking incident that has incensed brazilians, already furious at police brutality. translation: this is the moment when the black movement - is organising itself to respond to the massacre and genocide that is taking place. calls for justice for the asphyxiated 38—year—old, who died after being forced into a police car. translation: no-one is going to defend our lives, _ no matter where we are, whether in parliament or the social movement!

we are black people, at risk! death is at our heels! the family of genivaldo de jesus santos say he was on his motorbike in a northeastern brazilian city on wednesday when police asked him to lift a shirt, but he got nervous when officers found his prescription medication for schizophrenia. he was then forced into a police car boot, where a gas grenade was set off. this image, recorded at the time, shows two officers holding down the boot the man was in as thick smoke billowed from the car. translation: | asked| and begged the police, "for the love of god, get my brother out of there! get him out of there!" they replied, "no." the police paint a different picture. they say mr santos was arrested because he actively resisted their approach and because of his aggressiveness, immobilisation techniques and "instruments of less offensive potential", in their words,

were used to restrain him. but federal police are investigating the incident and brazil's highway police say disciplinary proceedings are under way into the officers' conduct. there was further agony earlier this week when police were accused of using excessive force and even torture when more than 20 people died in a raid in a rio dejaneiro slum. we're talking about a really violent week in brazil, but not a unique week, you know, because we always have weeks like this in brazil. but these allegations of the police gassing someone in their custody to death are not likely to be easily dismissed. as the last three minutes of genivaldo dejesus santos's life caught on camera, now put the authorities firmly in the frame. mark lobel, bbc news.

real madrid has won the uefa champions league final for the 14th time, beating liverpool i—0 at the stade de france in paris. liverpool dominated the first half, but despite several chances to score, they couldn't put the ball away. just before half time, karim benzema put the ball in the back of the net, but after lengthy discussions, he was declared offside and the goal was disallowed. real madrid came out fighting in the second half putting the liverpool defence under pressure time and again and it paid off when viniciusjunior scored, putting real madrid one up. liverpool were unable to claw back an equaliser, giving real madrid their 14th uefa champions league win. but there was drama before the match got under way as our correspondent danjohnson reports from paris. it is only minutes after the final whistle but already, tens of thousands of liverpool fans have dispersed from the fan park here. there were 30—40,000 liverpool

fans crowded here to watch the game on big screens. those who did not have tickets for the match, there would have been a huge party here had they won, but instead everybody has disappeared quite quickly because they are, no doubt, disappointed. they are heartbroken that they have not been able to claim their seventh champions league title but they are also disappointed about the way the game was delayed and there is criticism of the police and uefa of a lack of organisation which meant that kickoff had to be knocked back 30 minutes. we had a statement from uefa that said in the lead—up to the game, the turnstiles at the liverpool end became blocked by thousands of fans who purchased fake tickets which did not work in the turnstiles, creating a build—up of fans trying to get in and as a result the kickoff was delayed to allow as many fans as possible with genuine tickets to gain access. as numbers outside the stadium continue to build up after kickoff, the police dispersed them with tear gas and forced them away

from the stadium. even as fans have been leaving here in the last few minutes they have reported that the french police have been using tear gas. they complain the police have been very quick to move to that level of action with no real provocation. liverpool fans here have been overwhelmingly very well—behaved. there was a huge and positive hopeful atmosphere here this afternoon. so many thousands of liverpool fans positive that they could take home the european cup for a second time but it was not to be. sports broadcaster roberto rojas gave us a perspective on the match from the us. i think the misorganisation we saw in paris is surprising for many americans, the fact that, for an event so big, so watched all over the world, because of the lack of organisation, it surprised a lot of us and i think we were in shock that in 2022 that these kind of events still happen. so hopefully that, obviously it did not become the worst of circumstances and hopefully future champions league finals

and other events that happen in the sport are able to take lessons from it and improve from it moving forward. it was perhaps the expected result for many but liverpool fought hard and missed some chances. what the highlights for you? a liverpool team that was very much controlling the match. they had a lot of chances in the first and second half and they were unlucky to not get that goal in the first half. but leaning into that advantage in the second half. real madrid demonstrated the tournament, the fact that they were able to walk out and that they defeated the defending champions and perhaps some of the best teams in europe, i think it is a demonstration of that and liverpool were very unlucky. that was shown during the course of the year when they wanted a quadruple, they only got the fa cup and the league cup so they saw this as a saving grace but i think the experience, you know, the team knows how to play these type of competitions and they demonstrated that.

i think experience and obviously how proficient these teams are demonstrated that fact in the final and i think we saw that overall in the end in paris. you are watching bbc news. a reminder of our headlines: france and germany urge president putin to engage in peace talks, as russia continues its offensive in the donbas region. the russian ambassador to the uk tells the bbc that moscow will not use tactical nuclear weapons in the battle for ukraine. president biden has renewed his appeal for tighter gun controls following the texas elementary school shooting, as the parents prepare to bury their children. as may draws to a close, parts of india and pakistan

have recorded their hottest spring on record. the heat has also threatened india's wheat crop causing a government ban on exports of the grain. spells of pre—monsoon heat are not unusual in india and pakistan at this time of the year but the rapid onset and severity has this spring worse. earlier, i spoke to dr andrew king, a senior lecturer in climate science at the university of melbourne, and asked him if these heatwaves are particularly unusual. this has been an exceptional heatwave, particularly in terms of its persistence. we've seen heat all the way through from march until the present, in especially northern india and eastern pakistan — really exceptional temperatures at sometimes even around 50 degrees celsius. so really unbearable heat. what is it like, 50 celsius? what does it do to a human being and animals? i mean, those kinds of temperatures are really hard

to cope with. we know that when we have very high temperatures we see increases in heat stress and related illness. it imposes a strain, especially on the young and the elderly, and it poses a strain on animals as well. it is really hard to live with, and especially this region of the world, where many people work outdoors. it's harder to escape the heat than it is in many other places. if this continues — which i think we all pretty much know it will — what will it do, what is the impact notjust to the region, but perhaps to the wider world as well? how does it affect the economy, production, people? it does pose a lot of problems. this is a very well—populated region of the world. many people have experienced this extreme heatwave just by the fact that many

people live in this area. so it obviously causes big problems, and economically, as well, as you mentioned, the wheat export ban, obviously coupled with other issues going on in the world, is causing lots of problems to food supply. at least 35 people have died in floods and mudslides in northeastern brazil. most of the victims died when their homes were buried in tons of mud following the collapse of a hillside in one of the poorest communities in the city of recife. at least a thousand people have been left homeless across the state of pernambuco. more than 70% of the area's average rainfall for the month has fallen in the past day. more storms are expected in the next few weeks. police in nigeria say they've begun a criminal investigation after 31 people died in a crush in the southern city of port harcourt.

a large crowd had gathered in a sports field where a church was handing out food to struggling families. the police said the crowd became uncontrollable and the organisers failed to calm the situation. hundreds of thousands of young russians have left their country — many because they oppose the war. many of them ended up in armenia, a country in the south caucasus which russian citizens can enter without visas. but not everyone feels safe in armenia, which is russia's strategic partner in the region. rayhan demytrie reports. a pop—up russian wedding in the remote armenian town of tumanyan. most of the guests have fled russia. yura, the groom, used to make animation films. after getting arrested for opposing russia's invasion of ukraine, he and his bride asya made

a life—changing decision. i never thought about moving abroad, seriously, but yes, now i don't think i can come back. and if you ask about the future, nobody knows. also, i think it is dangerous for me and asya to go back, because i think we are in the list. it is a list of so—called "traitors and scum" — in the words of vladimir putin — for russians who do not back his war in ukraine. polina was punished with two weeks in prison for attending an anti—war rally in st petersburg. they try to give you this feeling that you are nobody here and your voice is nothing. polina is not planning to stay in armenia. she does not feel safe here. some hotels were asked by police for data of russian guests, and also in just normal routine

talks, i can feel how people in yerevan cannot really get what is going on and they are on the side of my government which punished me and all my friends. so no, i don't feel really safe. despite yerevan�*s close ties to moscow, more than 100,000 russians have entered armenia since the start of the war. zhenya found work in this cafe catering for russian expats. translation: i used to travel to ukraine every summer. - i have lots of friends there and i don't like what is happening at all. of course i don't support it. it's a war between brothers. back in tumanyan, the guests and the newly—weds

have put aside their worries for the night. this is a celebration of love and the ever—changing circumstances of life. just a few months ago, these people were living in the comfort of their homes in russia. and now they are among the tens of thousands of new emigres in armenia, trying to make sense of this massive shift in their lives. yura and asya plan to open an animation studio here and begin life anew. rayhan demytrie, bbc news, armenia. how do you free a killer whale that is stuck in france's river seine? rescuers are using orca sounds to guide it back to sea. until now, officials have been at a loss about how to deal with the whale. stephanie prentice reports. it is a four—metre long killer whale that's been trapped in the river seine for around

ten days, and now experts say its situation has reached a critical point, and that if it isn't freed, it's at risk of dying. they've come up with a plan to play orca sounds using a drone to try and lure the mammal back to sea. translation: it's the least intrusive idea and the least | stressful for the animal. it's the first initiative. what is very interesting is that if it works it will change everything in this type of rescue in france. the sounds will playjust above the water along this part of the river stretching, from rouen to le havre, incrementally moving the whale to safety. whether it's still strong enough to save itself is up for debate. being in freshwater for so long has weakened it and there isn't enough food to keep it going. it's been seen flailing around in the water, and its dorsalfin now appears to have been affected. translation: the animal is in a bad shape and has i a lot of injuries. its fin is bent, which means

it's in a poor health. a group of marine specialists have decided that using ships or nets to herd the whale will cause further stress and danger, so its fate now rests on how effectively loudspeakers attached to the drone can mimic a fellow orca, calling it back to the sea. stephanie prentice, bbc news. the top prize at the cannes film festival, the palme d'0r, has gone to a satirical movie about two fashion models who end up stranded on a desert island with a group of billionaires. triangle 0f sadness was directed by the swedish film maker ruben 0stlund, who's won the prize twice. claudia redmond reports. we're all equal. that is so true. triangle 0f sadness is the winner of one of film public most prestigious awards, the palme d'0r, at the 75th cannes film festival. directed by ruben 0stlund, the biting satire about the worlds of fashion and the super rich,

set on board a luxury yacht, had an eight—minute standing ovation when it was first shown at the festival. i feel happy. i feel happy, of course. it's crazy, it's crazy. to be in the cinema, together with the audience in the lumiere, and to hear them clap and laugh and be upset, you know, all this different kinds of emotions, i am very, very happy that the jury acknowledged that and gave a film that is basically considered a satire or a comedy the golden palm. the film follows the story of a male model, played by harris dickinson, who finds himself on a luxury cruise, captained by woody harrelson. he can make you extremely uncomfortable, he can make you think, he can give you a sense of meaning, like there was a sense of purpose going to see the film and, at the same time, and perhaps more importantly, he makes you laugh throughout, which is quite a trick.

ruben is very wonderful at picking holes in our behaviour and our egos and i think with — with this character, i really had to try and let go of that and allow myself to be pathetic and, you know, and offer myself up as a piece of meat, and that's an absurd thing to do. three, two, one... applause 0stlund's second palme d'0r makes ruben 0stlund one of a small number of two—time winners including francis ford coppola and ken loach. claudia redmond, bbc news. that is just about it from the bbc newsround from now. don't forget, you can keep up to date from the latest of elements in ukraine from all of our correspondence and producers who remain their reporting on the latest for you it is all there at the bbc news website.

—— news room. there are live updates as well. you can always download the bbc news app as well. from ian the team, thank for watching. —— from me and the team. hello there. on saturday, the lion's share of the sunshine and warmth was found across the south and the west of the uk. temperatures were above 20 degrees in a few places, and at newquay in cornwall, beautiful blue skies overhead. further north and east, there was a bit more cloud and it did feel quite a lot cooler. and as we move through sunday, with high pressure to the north—west of us and low pressure to the north—east, that'll be driving quite a brisk northerly wind. and that will bring a rather cool feel for many. temperatures will be a little disappointing for the time of year. so, generally speaking, it will be rather cool through sunday, particularly where we have areas of cloud and some showers, which could be heavy and thundery. equally, there will be some spells of sunshine in between, but we'll see showers

from the word go across parts of wales, the midlands, some north sea coasts as well. showers drifting towards the south west of england, where they will turn heavy and thundery, and for many places, it will be rather cloudy. not least in the north east of scotland, where that cloud will produce some spots of rain. coupled with quite a brisk north or north—westerly wind, it will feel decidedly cool, just 9—11 degrees. maybe 11! in glasgow. not too many showers for southern scotland or for northern ireland. scattered showers across england and wales, especially for south west england and south wales, where some of the showers will be heavy and thundery into the afternoon. top temperatures 15—16 degrees. now, as we head through sunday night and into the early hours of monday, many of the showers in the south will clear, but at the same time will bring areas of cloud down across scotland. some showery rain with that, a few showers running down the east coast of england as well. and it's going to be quite a chilly night. temperatures widely down into single digits. one or two places 3—4 degrees briefly around dawn on monday. for monday, yes, we'll see some spells of sunshine, but often quite large amounts of cloud and some heavy, potentially thundery showers breaking out. just about anywhere could catch a shower. and those temperatures still a little below par, 11—16 degrees.

now, as we look deeper into the coming week, this area of low pressure is going to wobble its way westwards, so that will bring some showers at times once again on tuesday, some heavy, thundery ones in places. signs are it will slowly dry out a little through the week, but there's still a bit of uncertainty about the jubilee weekend forecast.

this is bbc news, the headlines: france and germany have urged president putin to engage in peace talks as russia continues its ukranian offensive in the dombas. the russian ambassador to the uk has told the bbc that moscow will not use tactical nuclear weapons in the battle for ukraine. president biden has renewed his appealfor tighter gun controls, following the texas elementary school shooting. mr biden is due to visit the town of uvalde — where 19 children and two teachers were killed — as the families prepare for the first of this week's funerals. protests have erupted in rio dejaneiro, after the video of a black man being starved of air in the back of a police car caused shock and anger.

the incident has reignited the long running arguements
