in the disappearance of madeleine mccann. it's the final stretch in a tight french presidential race, for marine le pen, and emmanuel macron. and art in the shadow of war. the ukranian entries at the venice biennale. and coming up in the sport, on the bbc news channel, tyson fury weighs—in nearly a stone lighter than usual for his heavyweight title defence against dillian whyte tomorrow. good evening. the united nations has described the war in ukraine as a horror story of violations against civilians and says there's growing evidence war crimes may have been committed. near the beseiged southern port city of mariupol us satellite images appear to show a mass burial site containing around 200 graves. russian forces have been trying to fully capture the city for several weeks. they do control most of the area, but hundreds of ukrainian troops are still hiding out in the sprawling azovstal steel plant. today president putin accused ukrainian leaders of refusing to allow their soldiers to surrender. our correspondent catherine byaruhanga has more from southern ukraine. haunting, apocalyptic scenes in mariupol. russia has bombarded this city into near submission. once home to about half a million people, thousands are believed to have been killed. emergency workers from russia are filmed here, retrieving the dead. moscow has repeatedly denied that its troops are responsible for the mass killings of civilians in ukraine, but mariupol�*s mayor says some of the worst war crimes have been committed there. translation: they | killed 20,000 people. they did it on purpose. this is what i think. they intentionally prevented people from leaving mariupol. they set this genocide up by closing the city down and using land artillery and air strikes first, and then the warships that arrived later. russian forces have been accused of hiding civilian bodies in mass graves. these satellite images show them appearing over the course of a month. the civilians have been buried in the village of manhush, outside mariupol, the southern city which has been besieged and encircled by russian forces for weeks. the last ukrainian troops in the city are holed up inside the azovstal steelworks, on mariupol�*s coast. 1000 civilians are still said to be in this sprawling industrial complex. on this missing persons wall, most of the faces and names that you can see are people from mariupol, and now, with the ongoing blockade and with communications cut off, it's almost a miracle for people to get out. these women escaped mariupol together on thursday — just a handful of people who made it through with a humanitarian convoy. a friendship born out of the horrors of this war. translation: people are risking their lives under fire. _ they have to because there is no running water, gas or electricity. there is a mosque in the prymorskyi district with a well nearby. a lot of people got killed there. they got caught up in shelling. they were just looking for water in the city. but they are safe now and able to rebuild their lives in new cities and countries. catherine byaruhanga, bbc news, zaporizhzhia. borisjohnson says there's a realistic possibility the war in ukraine could continue until the end of next year. but, speaking on a visit to india, he insisted vladimir putin would not succeed in trying to grind the ukrainians down. miles of defensive trenches have been dug around the capital, kyiv, as a precaution should russian troops return, with life now less precarious after the city was successfully defended few weeks ago. our correspondent mark lowen has been spending time with ukrainian troops in the capital. gunfire for the defenders of kyiv, the battle isn't over. this time, its training, but while the enemy has retreated to the east, the danger still looms. vlad was a phd law student until the russians tried — and failed — to seize his city. do you think it is possible that they could come back? let's say we lose our positions on donbas or luhansk region, and then they see that we don't have enough troops and resources to protect kyiv, they would come back for their initial aim to take over our capital and take over our government. in the forests of kyiv — we can't disclose where — the isist battalion is dug in, a crucial line of defence for the capital. how many kilometres of the trenches? i don't know. ten kilometres, 20 kilometres, i don't know. great britain sent us these weapons. it says anti—tank missiles from britain. yes, yes. and when was the last time that you used this weapon here? secret. translation: the russians were three or four kilometres from us, _ firing with mortars and artillery. if they return, without our resistance, they could storm through, and they will make an effort to do so again. but i think the residents of kyiv can sleep more soundly knowing that we are here. a whole infrastructure is in place. spots where kyiv families would picnic now have new dwellers. soup? it still feels astonishing to see how a modern european capital has suddenly been taken back to the trench—filled warfare of decades ago, and they're in this for the long haul because they now know that the threat to the very existence of their country will continue. forthose dug in, reminders of the life they left behind two months ago, when russia thought it could barge into kyiv with little resistance, and when ukraine's residents became its protectors. mark lowen, bbc news, kyiv. our diplomatic correspondent paul adams is here. well over 50 days so far of this well over 50 days so far of this conflict. what might success look like for either ukrainians or vladimir putin? i like for either ukrainians or vladimir putin?— like for either ukrainians or vladimir putin? ~ ., , , ., vladimir putin? i think for russia, clearly success _ vladimir putin? i think for russia, clearly success has _ vladimir putin? i think for russia, clearly success has been - vladimir putin? i think for russia, | clearly success has been redefined almost every day. the invasion was premised on a quick assault on the capital, removal of the zelinsky government and the installation of a puppet regime. that didn't work, so focus shifted to the donbas, extending areas held by pro—russian separatist and east and securing the land corridorfrom separatist and east and securing the land corridor from the separatist and east and securing the land corridorfrom the donbas to crimea, which russia annexed in 2014. that is why mariupol is so important. you still get glimpses of wider ambitions. we had a russian generaljust today wider ambitions. we had a russian general just today talking about seizing all of southern ukraine, creating an even longer corridor to another pro—russian separatist area, transnistria, in moldova. that would involve completely cutting ukraine off from the black sea. i think given russian setbacks so far, that seems a rather distant prospect. western officials do warn that if the assault on the donbas goes well for vladimir the assault on the donbas goes well foeradimir putin, he the assault on the donbas goes well for vladimir putin, he might well start to think big again. for ukraine, well, just repelling russia's advances in stopping them taking more territory as the number one priority. if they do manage to do that, and the west is hurling new and heavy weaponry into ukraine, speeding that up, then ukraine may sense an opportunity to roll back those russian advances, back to where we were on february the 24th. that would be a spectacular success for ukraine but it would mean taking back a lot of territory. maw; back a lot of territory. many thanks. borisjohnson says he still expects to be prime minister by the time the uk hopes to sign a new trade deal with india in october. he was speaking on his visit to new delhi, after talks with prime minister, narendra modi. mrjohnson is facing a commons investigation, into whether he misled mps over what he knew about lockdown parties at number ten. our political correspondent, ben wright, has more from new delhi. the sun shone, the soldiers saluted and the ceremony never flagged. it was the red carpet treatment for boris johnson who was here for talks with his indian counterpart, narendra modi. after yesterday's torrid day of political turmoil at home, mrjohnson seemed pleased to bask in the welcome. a joyful reception, i wouldn't get that necessarily anywhere in england. this is when the visit got down to business. it's 75 years since india gained independence from britain and both countries say a free trade deal can be signed this year to mark the moment. next week, we're telling our negotiators, get it done by diwali in october. they had a long discussion about ukraine. india has held a neutral position on russia's invasion and borisjohnson did not come here to jab or pressure, but mr modi did call for peace. translation: we emphasise on an immediate ceasefire - in ukraine, and on the use of dialogue and diplomacy for resolving issues. while borisjohnson later confirmed the uk intended to deepen its military commitment to the crisis. so we're looking at sending tanks to poland. that's to allow warsaw to send its tanks to ukraine and the prime minister also said british diplomats would soon be returning to the capital. i can announce today that we will very shortly, next week, reopen our embassy in ukraine's capital city. it's been a difficult couple of days for the prime minister, who is now facing an inquiry by mps into whether he misled parliament. you said there will be a free trade agreement with india by diwali but considering the number of party investigations going on back home, are you absolutely sure you'll still be prime minister then? ok, the second answer is yes but... all trade agreements are tricky, to get to your point about trade, ben, and there will be tough asks of both sides, but i'm sure we can do it. boris johnson bristles at any mention of parties and the political problems he faces back at westminster. he is clearly irritated that it's taken the focus away from his efforts to deepen britain's ties with this surging economy. but it's where the party saga goes next that could determine borisjohnson�*s future as he returns to domestic political strife. ben wright, bbc news, delhi. a man has been declared an official suspect in the disappearance of madeleine mccann nearly 15 years ago. she went missing during a family holiday in praia da luz in portugal, in may 2007, shortly before her 4th birthday. her parents say they welcome today's development, and that they haven't given up hope madeleine may still be alive. our correspondentjon kay has more from praia da luz. her face and name are known around the world, but what happened to madeleine remains a mystery. it was on the 3rd of may 2007 that she vanished from the mccanns' holiday apartment in praia da luz — the moment herfamily�*s lives changed forever. please give our little girl back. overnight, portuguese prosecutors announced that they'd declared a new "arguido", or "formal suspect", in the case. it's understood to be this man, christian brueckner. the 45—year—old is currently in prison in germany pfor rape and drugs offences. he's known to have been living in portugal around the time madeleine disappeared, and german investigators say mobile phone records place him in praia da luz. but he has denied any involvement in the mccann case and has not been charged. you know, you have proximity, you have opportunity and you have a profile, with regards to an offender that absolutely fits in the way that no others have. the last decade and a half have seen many potential breakthroughs come and go. madeleine disappeared from her family's apartment while her parents were dining at a restaurant in the complex, and in the early days of the investigation, the portuguese authorities made kate and gerry mccann official suspects, but that status was later withdrawn. injuly 2013, the uk's metropolitan police reviewed the case, saying they had new witnesses and new evidence and they searched areas close to where madeleine was last seen. it was injune 2020 that german police said they'd identified a prisoner as a suspect and the timing of christian brueckner now being made an arguido appears significant. next month, it will be 15 years since madeleine was reported missing, and under portuguese law, it's not possible for someone to be given arguido status after 15 years. but the authorities here say the move was not driven by timing but by what they call "strong indications" of the practice of a crime. here in praia de luz, people are asking what will happen now. will the authorities travelled from portugal to germany to interview this man in prison, or might they try to bring him here for questioning? meanwhile, as we approach the 15th anniversary, her parents have issued this statement tonight, saying that they cautiously welcome the development and say they still have hope that madelyn might still have hope that madelyn might still be alive, and they say one day they hope they will be reunited with her. the final day's campaigning is nearly over in france's presidential election, with voters going to the polls on sunday. the choice is between the incumbent, emmanuel macron, and marine le pen. millions are still thought to be undecided. with the very latest, my colleague reeta chakrabarti is in paris for us tonight. yes, here in paris — as across the country — there is a fear that antipathy towards both candidates is the one thing that unites voters. but when people go to the polls this sunday, they'll be voting for very similar issues to those we are facing at home — namely the cost of living crisis and ukraine. emmanuel macron is having to defend his record of five years in government, and it's been patchy, while marine le pen, although she's worked hard to soften her image, is viewed by many as extreme and far—right, and her proposal to ban muslim women from wearing the headscarf in public places is particularly controversial. our correspondent lucy williamson has been following the candidates on their last days on the campaign trail. it's a bit late for tips on how to learn to punch on his opponent. after five divisive years in power, what emmanuel macron needs is to persuade voters who'd quite like to punch him to give him their vote instead. florentine and chloe are both teachers here in the suburbs of paris. they voted for mr macron last time. now, they've come to give him a hard time. le pen isjust...huge disaster, but macron is still a disaster, i think, for school and for public services in france. he's killing that, step—by—step. florentine says she'll abstain on sunday rather than vote for macron again. i'm still hesitating. i think if i do it, i might really get sickjust after. he's a good talker, he knows how to try to seduce people, but we're not stupid. chloe gets close enough to shout her question on teacher's pay. "do you think teachers are lazy?", she asks. through the scrum, macron grips her hand, and locks in her vote. translation: he gripped my hand and said, "we're going to do - "something about that, i promise" _ so, i will vote for him, - but i want something in return. there's a real choice on sunday about where france is heading. marine le pen is promising huge tax cuts and to "take back control". emmanuel macron wants a global nation, set on economic reform. divisions here are deepening with every election cycle and voters are now split between two radically different views of the world — with one candidate presenting herself as the spokeswoman of the people, and the other saying he's protecting france from her. dylan says he voted far—left in the first round of this election. on sunday, he's voting far—right. translation: it's not that i like the idea - of voting for marine le pen, but we have to choose between the two, and when you're choosing between cholera and the plague, you choose the lesser of two evils. at herfinal rally, here in arras, marine le pen said voters should choose her to block mr macron. both say the other is dangerous. both spark loyalty in their own fans and loathing in those of their rival. but most voters belong to neither camp, and in this battle over france's future, they're being asked to choose a side. lucy williamson, bbc news, paris. our europe editor katya adler is with me. so two competing visions of france and also its role on the world stage? dramatically different worldviews, taking the eu for starters. emmanuel macron is an eu enthusiast, he doesn't want the united states of europe but he is a passionate believer in the european project. marine le pen is deeply eurosceptic, backing away from the idea of taking france out of the eu but brussels is worried that if she becomes president, she will try to destroy the block from within. you can say it's just one country out of 27 and what does it matter? it does because france is the second largest economy in the eu and has the biggest single military force in the eu as well. it is also a big player in nato and that matters now particularly because of the russia— ukraine crisis. marine le pen has historically close ties to moscow and wants to take front out of nato's military command and that worries europe. we have had the leaders of spain, portugal and germany writing to a french newspaper saying that french voters don't support marine le pen and something similarfrom don't support marine le pen and something similar from the don't support marine le pen and something similarfrom the ukrainian president so the choice of french president has a huge impact here but outside france as well. man? president has a huge impact here but outside france as well.— outside france as well. many thanks. ka a outside france as well. many thanks. katya adler- — well, the race is far closer than it was five years ago, and the big question is — what will the 49% of voters who didn't support either candidate in the first round do in this election? will they lend their vote to macron or le pen, or will they say none of the above and just abstain? we'll know on sunday. that's it from me in paris. now back to you, clive. reeta, thank you for that, lived in paris. a woman has been found guilty of gross negligence manslaughter, following the death of her seven—year—old son. hakeem hussein was found dead in a garden in birmingham, in november 2017. he was severely asthmatic, and coventry crown court was told he was left alone without his inhaler. our midlands correspondent phil mackie reports. hakeem hussein was a frail young boy who died because his mother cared more about getting her next fix than looking after him. laura heath smoked heroin and crack cocaine. her addiction had spiralled out of control in the months before he died. she even used her son's inhaler as a makeshift crack pipe. they lived in squalor. their lives were chaotic. on the night he lost his life, hakeem had a severe asthma attack, went outside for some air, but collapsed and died. his mother couldn't help because she'd passed out after taking drugs, but later, she wrote her dead son a letter in which she appeared to blame him for not waking her up. evidence showed that he was simply neglected. his mum prioritised her drug use over him. hakeem wasn'tjust failed by his mother, but also by the agencies who were responsible for him. they'd had plenty of warnings over a period of two years that culminated in a meeting on a friday afternoon at which a nurse said if he wasn't taken into care immediately, he would die. no action was taken. 36 hours later, his body was found here. at the time, birmingham children's services had already been rated inadequate for nearly a decade. six months after hakeem died, a new trust was appointed to take over, and inspections have shown improvements. all of the agencies working together had not shared or sought from each other enough information. one of the things that would happen today that didn't happen then is that that would have triggered an immediate response that afternoon. a serious case review will be published soon. it's hoped that changes already made will minimise the risk of another case like hakeem's. phil mackie, bbc news, birmingham. retail sales in the uk have fallen for the second consecutive month, as the rising cost of living hits consumer spending. sales were down 1.4% in march, a much larger drop than expected. online sales also fell by almost 8%, as consumers cut spending on non—essential items. and there was a big fall in demand for petrol and diesel. the cost of filling up an average family car with petrol now stands at almost £90, 32% higher than a year ago. in just under two weeks' time, voters in the english local elections will head to the polls with thousands of seats up for grabs. our political correspondent, alex forsyth, has been to bury, in greater manchester to find out what issues are at the forefront of voters' minds. phone rings good afternoon, melissa janes. business is getting back to usual at this hair and beauty salon in bury, but it's been a tough few years. and with the economy still feeling far from smooth, it's clear what's on many minds here ahead of next month's local elections. i'd say the after effects of covid and the lockdown, then the price increases and the national crisis that we're all in. i feel it's just — this now is harder than the initial, you know, the initial lockdown itself. it's more the fact that, like, if the salon can keep me employed and whether i'll keep myjob. but that's the main thing, really. i have noticed a massive impact on my business. | just again, with the | uncertainty of it all. so, are they convinced anyone has the solutions? i have no confidence in any particular politician at the moment. i think whichever way it goes, they'll all have a hard battle in trying to recover from the mess that's been made. in bury, and across england, these local elections will be a crucial reflection of the public mood. at this independent coffee and vinyl shop, they're interested in who'll do best for the area. which party is going to help the business, which is going to drive more people into bury, and what policies they've got around helping that, and making sure that there's plenty of people on the streets. it's clear people here care about local issues. after all, these elections will determine who runs local services. but the big picture counts, too. for the conservatives, this is a public verdict on gatherings in downing street and the government's response to the war in ukraine and spiralling prices. for labour, it's a question of whether people think they have any of the answers. the lib dems are trying to tap into frustration among voters to win support. there's much to play for. at bury croquet club, there is anger at lockdown events in westminster. less obvious is what impact that might have. i'm just appalled that anybody, you know, in any position could think that it's right to actually have drinks at work. and i think it's going to take a lot to get the trust back, regardless of which party you tend to traditionally vote. boris, yes, he's had his parties. even though it's not right, i'm sure he's not been on his own. would those kind of things factor into how you'd vote locally? i think locally, it matters what's important to the candidates and how they're going to respond with the money they've got and how they're going to spend it locally. with the greens and a host of other parties pitching for votes, these are local elections with national consequences. they'll show which parties are on course and which might need to change. alex forsyth, bbc news, bury. the world's most prestigious international art event, the venice biennale, opens tomorrow, with ukrainian works centre stage against the backdrop of war. our culture editor, katie razzall, has that story. serene venice has been shaken by world events. first, its international art show was delayed a year by covid. now, that biennale is taking place in the shadow of war. all of which means, unusually, the art world is focused on ukraine. there is a new damien hirst for a show, defending freedom. and works by maria prymachenko, who is a symbol of the country's national identity. it is about showcasing ukrainian culture. one artist depicts her husband and others who have joined the army, painted as reports of war crimes against civilians in the kyiv suburb of bucha were revealed. and i was even crying because of bucha and this canvas was laying on the floor and i thought, ok, ironically, connect, you know, because of the... ..wetness of the painting is connected to my tears. russia's pavilion is shut. the artists and curator behind this year's show pulled out when the invasion happened. the only thing to see was an anti—war protest by a russian artist. he was surrounded by supporters. and then swiftly by police. he is a sole voice of protest but he does speak for many russian artists, and this russian pavilion is closed and, in a sense, those closed doors symbolise quite how isolated russia is. but some russian art is being shown at the bienniale, including tapestries by zhenya machneva. it's screaming, it's crying. all my feelings is here. zhenya opposes the war. we should stop it. and every day i want that it stops but it's hard to face, that each day it's getting worse. the ukrainian pavilion is now centre stage in venice. the artist behind this work, called the fountain of exhaustion, says it is important that his country is represented here because the russians are attacking notjust ukraine but its culture. they want to level and demolish totally ukrainian culture because it doesn't exist because it's part of russia. they are saying openly, that the war is a punishment for them, and those who doesn't want to go and to understand that this is only part of russia, they have to be physically eliminated. so whether it is photographs of mothers who have lost sons in the conflict, or a i7th—century icon, these works on show here now reflect a country, a culture, that is fighting for its very survival. katie razzall, bbc news, venice. that's it. now on bbc one, time for the news where you are. have a very good night. hello and welcome to our look ahead to what the the papers will be bringing us tomorrow. with me are susie boniface, who's a columnist for the daily mirror, and ali miraj, a columnist at the article. tomorrow's front pages, starting with the ft reports that the pound has reached its lowest level since 2020
