the death toll rises in south africa — following heavy flooding — with a warning more rain may be on the way. the archbishop of canterbury, the most senior cleric in the anglican church condemns plans by the uk government to send some asylum seekers to rwanda. the comments come on easter sunday. this is the scene live at st peter's square in vatican city where pope france has been celebrating easter mass. hello and welcome to bbc news. russia has urged the last ukrainian forces defending the besieged port of mariupol to surrender within hours, in order to save their lives. the city has been under siege for weeks. moscow says its troops have cleared resistance from the entire city, apart from a sprawling steelworks. ukraine says its naval units are preparing for a russian landing operation in the area. in a late—night address, president zelensky accused russia of deliberately trying to destroy mariupol — and everyone in it. mr zelensky warned that eliminating ukrainian fighters in the city would put an end to peace talks. meanwhile, explosions have again been heard in the capital, kyiv and in the western city of lviv. air raid sirens have been going off across much of the country overnight. this report is from helena wilkinson. forweeks, mariupol has been battered by sustained russian attacks. the kremlin says it's now cleared urban areas of ukrainian forces and it's made this offer to ukrainian soldiers fighting in the port city — lay down your arms by later this morning and your safety will be guaranteed. earlier, the president of ukraine had this warning for russia. translation: the elimination of our troops, of our men - in mariupol will put an end to any negotiations. there is a humanitarian crisis, there is a lack of food, water, medicine. however the guys are heroically defending themselves. we are grateful to them for that. the president's warning comes as a second british fighter has reportedly been captured by russian forces in mariupol. a video of the man, who gives his name as sean pinner, emerged after aden aslin was detained earlier this week. meanwhile, russia continues to carry out airstrikes elsewhere in ukraine. in the capital, kyiv, one person was killed and several were wounded. residents have been warned by the mayor not to return over fears of further attacks. explosions were also reported in the western city of lviv overnight, where air defences reportedly destroyed four russian cruise missiles. earlier this week, russia's prize warship sunk in the black sea — ukraine says it struck the vessel, the kremlin denied that, saying an explosion onboard caused it to sink. now the russian defence ministry has published images showing what it says is the ship's crew, the undated video showing sailors on parade being inspected by the commander—in—chief of the russian navy. the focus today will be on what happens next in mariupol. will the remaining ukrainian soldiers there ignore russia's deadline offer to lay down their arms and continue to defend the city to the end? helena wilkinson, bbc news. the great—granddaughter of soviet—era leader, nikita khrushchev, has told the bbc that president putin may be prepared to use battlefield nuclear weapons if necessary to win the war in ukraine. nina krushcheva, who is an international affairs professor based in new york, said the russian president saw himself as the latest in a long line of strong russian leaders. she was asked if there was anything that could stop him. yes, there is, president putin will stop president putin i think. but i don't really think that vladimir zelensky�*s pleas are going to really work for putin at all because the russians, the russian side already said that the ukrainian side has been withdrawing from negotiations, changing its position. so the fact that zelensky now says that there will be no negotiations if soldiers are mariupol will get killed, probably for putin is not is not a surprise. it is possible that mariupol will fall and it is possible by may, by may 9th. i'm sure you know there is a victory date world war ii victory day on may 9th. so there is rumours back and forth that putin would like to stop the war or at least declare some sort of victory by then. so it is possible that with the taking of mariupol, that could be one of those prizes and sort of a declaration for at least the completion of this stage of the war. but once again, i think putin knows only what putin knows. we don't know. even those who are expected horrible things from putin like me and a lot of others, i am still completelyjust stunned by the brutality that's being exerted on ukraine altogether. and it does seem that at the beginning at least, they were sort of more cordial approach to the war. but once ukrainians started fighting back and and hitting back then, the russians became as brutal as possible. and also they've been changing troops a lot. and i think the russian guard has been particularly and also the chechen, the the chechen battalions from north caucasus. they've been particularly brutal, so it actually depends what kind of troops they have. but generally, i think this war is really the one that putin plans to win and plans to win at any cost. with me now is lord peter ricketts, the former uk permanent representative to nato and a former national security advisor to the uk government. i was wondering if you caught the end of what the professor had is this vladimir putin is walk to when at any cost?

"the world is facing a global migration crisis on an unprecedented scale and change is needed to prevent people smugglers putting people 5 lives at risk and to fix the broken global asylum system." our political correspondent, ione wells, is with us in the studio. to cut through what he has been saying and how significant this is. i think it is a significant intervention and it is not usual for the archbishop of canterbury to make such a strong comment on government policy. opposition parties criticised government policy but less of what he describes as the judgment of god. later in his easter sermon he says the government asylum policy cannot stand up to the judgment of god and cannot carry the weight of a responsibility as a country founded on christian values and also it is opposite to the nature of god who he says to cut response ability for our failures. it is all in response to a recently announced uk government policy to send asylum seekers who have arrived to the uk via for example boats crossing the channel are lorries making that crossing to rwanda to have their asylum claims process there as opposed to in the uk. many people, even politicians will probably see should the church be doing politics? what reaction has been from the home office? the home office have responded quite robust with the claims he has made and said there are a number of safe and legal routes for people who want to seek asylum in the uk like existing resettlement schemes and also said the uk has a proud history of welcoming refugees in need and said their plans and their views would disrupt the business model of people smugglers particularly involving people wanting to cross the channel into the uk. the archbishop himself has acknowledged the details of the scheme are for politics and i think we will see a lot of this next week. this policy was announced when mps were off for the easter break be back on tuesday and i think there will be a lot more debate when they are back then. we can get the latest from our correspondent in lviv, dan johnson. let's remind of the latest developments and the highest concern is what is taking place in mariupol. there are reports of this morning of more attacks on the edge of kyiv. a district to the east of the capital city where an attack that is said has hit some of the local infrastructure there. we're not sure what the target was or the of damage. that has been the case after a few notes after russia threatened to step up attacks and there were air raid alerts right across the country. in mariupol russia has offered ukrainian soldiers the chance to surrender and says if they put down their weapons and we white flag and hand themselves over from the steelworks which has been the scene of a really intense battle over the past few days. i'm not sure if this is a sign that russia is struggling to complete its takeover of that plant and therefore the city of that plant and therefore the city of mariupol our demonstrates how dire it is not for the remaining ukrainian soldiers. russia says that a 2500 of them but no sign as yet of ukrainian soldiers taking up the offer. russia has said there are only few hours left for the offer to be taken up. president zelensky says if the soldiers are killed that will close the chance of negotiations. it is a desperate situation for people there and it is symbolically and strategically important as a city which russia is keen to claim victory over even despite the fact it has bombed the city to ruins. there is one thing some people will ask, in terms of attacking kyiv why once again are they doing that and how are they doing it because we understood a number of days ago they had pulled out of a number of areas around the capital so how are the targeting in terms of missile those suburbs that are being hit? the russian forces that were approaching the capital city and occupying areas to the north of it all pulled back more than a week ago and those areas are clear of troops know. there are still dangerous because minds were left behind but the russian forces withdrew and i know focusing instead on the east of the country. we have seen renewed attacks coming from russian jets flying launched seen renewed attacks coming from russianjets flying launched mainly from russia or belarus. they have targeted mainly so far military targets and yesterday it was a munitions factory that was set and it hit the factory that makes the sort of missile ukraine claims was used to sink in the moskva, the flagship of stop the risk is civilian targets may get hit, may be inadvertently, and also when ukraine air defences shoot down missiles we sometimes see the bits of the missile left after those explosions can cause damage in other areas so to something that will concern people right across ukraine and the fight there have been so many air raid warnings in the last few notes as a reminder to people across the country of the risk they face even if they're away from intense fighting in the east. as nearly 400 people are now known to have died in flooding in kwa—zulu natal, the south african president, cyril ramaphosa, has postponed an official visit to saudi arabia in order to focus on the devastation. specialist rescue teams are searching for dozens more who're still missing. more than 13,000 homes have been damaged in the disaster. vumani mkhize reports. a deadly flash flood swept through this informal settlement north of durban in the middle of the night on tuesday. people here ran for their lives as the rising floodwaters engulfed everything in its path. the mangled remains of debris are what's left. sombre residents look on as a rescue team searches for the missing. a recovery operation is underway here at the cocobod informal settlementjust north of durban. members here of the rescue team are essentially looking for two people, a youngster aged eight years old and someone who's also aged around 30. and as you can see over here, their cars and debris that have been strewn all along along the river. and it'sjust an indication of the severity and the violence of the water that was cascading along here. the search and rescue team can't get heavy machinery into the area. they painstakingly use their bare hands. so currently we've got two community members missing in this area. we brought in canines because, as you can see, it's a very big debris pile. a lot of material to move. a lot of heavy logs, vehicles, household items so we can't exploit the whole area. community members are traumatised by the floods and are finding it difficult to come to terms with what happened. translation: we are in pain. we can't even sleep properly at night. every time i close my eyes, i can just see the rain and water coming. i can't sleep and i can't eat. this woman who lost her house tells me she wants the government to help her find shelter because she can't live here any more. up on the hill, this man shows me where the informal settlement used to be. and there were people that are also found there as well, right at the top? wow. there was something like seven people. seven people were found and they were found alive, though, right? yes. the search and rescue operations are continuing throughout the kwazulu—natal province as more remains are being found. for nearly two months now the people of ukraine have been dealing with life in a warzone. many have been killed — others have left the country. everyone else tries to make the best of things. in the city of dnipro — a group of local musicians are hoping to lift spirits — as tim allman reports. orchestra plays james bond theme. the people of this city and this country have been both shaken and stirred, so what better to meet the mood than a little james bond? these musicians, some from a local academy, have grouped together to form a street orchestra, bringing a little hope in these troubled times. translation: the idea came up that we need to play for people, | especially nowadays, to bring some positivity to people at a difficult time. head north to the besieged city of kharkiv and the best place to be is underground. oleksandr and anton put on a puppet show for the children who have to shelter here. a distraction for a moment or two at least from the bombardment this city is having to endure. translation: for me, the exchange of emotion is very important. - we give the children our emotions and they give us theirs and that lifts our spirits. we can't name it, you have to feel it when you see the reaction. and in the capital, kyiv, an easter vigil takes place, another moment of normality in a country where that is now rare. they pray for salvation, they pray for an end to war. tim allman, bbc news. let's find out the weather is looking. it looks gorgeous behind you. is that what can expect?
