westerners. shocking scenes in shanghai: clashes between the police and the people as the city's strict covid lockdown enters its third week. hello and welcome. volodymyr zelensky says european countries that continue to buy oil from us are aiding the russians war against them and will have blood on their hands. he's urged western leaders to speed up the delivery of military aid to help ukraine. he's been talking to the bbc�*s clive myrie, who sat down with president zelensky in his wartime bunker. —— we're getting reports that powerful explosions have been heard in the last few hours in kyiv and a number of other cities across ukraine. the capital remains tense and fearful of the ——of an assault. mr president, clive myrie. a pleasure to meet you. it's good to see you. for the entirety of the war, volodymyr zelensky has called this heavily fortified building home in the centre of kyiv. how difficult has it been for you to be here through all this without your family? it's myjob. i have to do it and it's difficult without a family being anywhere. his wife and children are safe at an undisclosed location. his companions here — heavily armed troops, sandbags and mines. there was no light at all? you kept everything...? at the start of the war, they walked around in the darkness here, afraid of russian shelling. it's, like, — like our country, like our country is going through the dark... going through the darkness. to do the victory — i hope so. as we enter what is labelled the situation room, the president gets a text. 0h, oh, it's emmanuel macron? yeah, he phoned me — we have connections. 0k, he dropped you a message. oh, i can see it! laughter. i don't know! he just tried to reach you, my friend, when you have some time, so we are holding up mr macron. yeah. i can see the plus 33, that's paris. yeah. that is true. a few minutes later, he returns. his preoccupation — a renewed military onslaught about to begin in the east. are you getting the right weapons you need from the west? translation: we need weapons today, so we can fight. _ we cannot wait until some country decides to give or sell us weapons. some have still not decided on this, and we cannot wait two or three weeks or a month. the united states, the united kingdom and some european countries are helping, but we need it sooner — we need it now. is it enough? we don't think so. in english: the priority word is sooner, the priority word i is quickly and the priority word — now. he is a president who has been cut off from his people, a citizenry suffering unimaginable horrors at the hands of a ruthless adversary. he's full of hate, he says, for russia's troops and their leaders, gradually limiting the scope for peace talks. how do you sit across the table to try to stop the war? how do you do that? bucha is in this process, closing these possibilities. bucha, borodyanka, mariupol. so i don't have — you know, it's not about me, it's more about russia. they will not have so many chances in the long period to speak with us. and what of those european countries, despite other sanctions, still sending billions to russia in oil and gas revenues? translation: we don't - understand how you can make money out of blood. unfortunately, some european countries have done this. before the war began, i spoke to chancellor merkel and said, "if a full—scale invasion of ukraine happens, "they will go further into poland and, after that, "they will be on your borders of germany. "if that happened, would you say to young people, "it's fine. "it's business. "it's just business?" how do you maintain hope in the future, given everything that's happened? translation: it's not hope, it's certainty. i that you will win. yes, of course. mr president, thank you. thank you so much. russia's defence ministry says the flagship of its black sea fleet, the cruiser moskva, has sunk a day after ukraine said it had been hit by missiles. russia has not confirmed ukraine's claim, saying only there was a fire aboard that set off ammunition. the ship went down as it was being towed back to port in stormy weather. it's being described as a big blow to the russian fleet. tim allman reports. the scourge of the black sea now buried at the bottom of it. the moskva, or �*moscow�* in english, was a symbol of russia's military might, and crucial to its operations in ukraine. what caused its demise remains disputed. ukraine says it hit the moskva with neptune cruise missiles launched from the coast. russia would only admit there had been a fire on board after ammunition exploded. the 12,500—tonne ship was operating in an undisclosed location in the black sea when the incident occurred. it was being towed back to the port in bad weather when the moskva sunk. so this is a real moment of truth for russia, frankly, you know, early on. eventually, the truth typically does come out, but there is usually some kind of narrative around it and this seems a bit more forthright than we have seen in many of the weeks preceding. the satellite images show the moskva in port earlier this month. the warship had played a key role in russia's military campaign in syria and was leading the naval assault on ukraine. all this made it an important symbolic and military target. it is perhaps ironic that on the day it sank, the ukrainian postal service issued these stamps, marking a famous moment of the start of the war when border guards defied a russian ship on an island in the black sea. that ship is believed to be the moskva. translation: an important event happened. _ our armed forces destroyed the aggressor�*s flagship. i think this event has to have a place in everyone's memory. the truth of what really happened to the moskva will perhaps never be known, but it will play no further part in this war, or any wars. the impact of its loss on russia's military plans is also unclear, but this is the biggest warship to be sunk by enemy action since the second world war. tim allman, bbc news. let's get more analysis and reaction to the sinking of russia's black sea flagship. our russia editor steve rosenberg gave us this update from moscow. as the symbol of russia's black sea fleet, the moskva was an enormous symbol, really. a symbol of russia's military might. and the fact that this symbol has been engulfed in fire, has been put out of action, has now sunk while being towed back to harbour — that, i think, is a major blow to the prestige of the russian armed forces. and it kind of goes against what president putin was saying just a couple of days ago, when he declared that what he calls his �*special military operation�* was going according to plan. and talking of president putin, a couple of things struck me, — the first thing is how different the presidents of russia and ukraine are. on the one hand, you've got president zelensky trying to get his message out to the world, giving interviews to western journalists. vladimir putin hasn't given interviews to the western media since russia attacked ukraine. but there's one thing the two men have in common — publicly, at least, they both insist they're going to win. steve rosenberg. dmitry gorenburg is an expert on russian naval strategy in the pacific and the black sea at the centre for naval analyses. hejoins me now from boston. hello to you, thank you for joining us. we heard from our correspondent that this was a symbol of russian military might and power. it is now at the bottom of the sea. whatever the bottom of the sea. whatever the reason for its thinking, this has to be great for ukrainian morale and terrible for russian morale? absolutely. s mbolic for russian morale? absolutely. symbolic impact, _ for russian morale? absolutely. symbolic impact, i— for russian morale? absolutely. symbolic impact, i especially - symbolic impact, i especially connected to the incident at snake island that was mentioned earlier in the report is critical and ukraine has really sunk the largest ship in the black sea fleet and one of the largest naval ships in the world. �* , largest naval ships in the world. a ., , ~ ., world. as it also sunk in one ofthe world. as it also sunk in one of the biggest _ world. as it also sunk in one of the biggest threats - world. as it also sunk in one of the biggest threats to - of the biggest threats to ukraine, as russia continues its invasion of the country? interestingly, the moskva was not directly threatening the ukrainian territory because it does not have land attack missiles like some of the other smaller ships do. its primary mission in this war has been in terms of being a command ship and having radar that was able to help in terms of target identification and threat identification and threat identification for the other ships. its main armaments are anti—ship weapons and also air defence, from a point of view it's maybe a bigger symbolic blow for ukraine than it is in terms of countering a military threat. �* �* ., , ., , threat. the bbc has not been able to verify _ threat. the bbc has not been able to verify the _ threat. the bbc has not been able to verify the claims - threat. the bbc has not been able to verify the claims of i able to verify the claims of russia or ukraine of how and why this ship sunk but for a moment, let's suppose it was ukraine that sunk it. they say they used neptune missiles, and my understanding is they have not had those very long. they are ultimately being used to protect ukraine after the annexation of crimea. do you think there was a bit of luck involved in this, if it was ukraine?— involved in this, if it was ukraine? �* , ., , ukraine? i'm sure there was some, ukraine? i'm sure there was some. in — ukraine? i'm sure there was some. in part _ ukraine? i'm sure there was some, in part because - ukraine? i'm sure there was some, in part because this | ukraine? i'm sure there was i some, in part because this is, as was indicated, a very large ship so i think there may have been some fortuitous circumstances in terms of where the ship was struck, so then if the ship was struck, so then if the armaments on the ship exploded, that then contributed to it becoming unstable and thinking. my guess is that the ukrainian is expected to, at best, to damage the ship and put it out of commission, rather than sink it entirely. we must leave it there but many thanks for your analysis here on bbc news. good to talk to you. on bbc news. good to talk to ou. . ~' on bbc news. good to talk to ou. . ~ , ., on bbc news.

platform twitter. he's offered $54 a share for the company, valuing it at $40 billion. twitter�*s share price immediately soared at the news of the offer but some major shareholders, including the saudi prince al waleed bin talal, have already rejected the proposal. scores of people are still missing in the philippines following floods and mudslides triggered by tropical storm megi. more than 130 are now confirmed to have died. the islands are battered by more than 20 storms a year and scientists have warned the number could rise because of climate change. plans to send some asylum seekers who arrive in the uk to live in rwanda have been described as "absolutely chilling" by charities and politicians. britain's home secretary priti patel, who travelled to the rwandan capital kigali to sign the deal, said the "vast majority" of those arriving in the uk "illegally" would be considered for relocation to rwanda. new year a former british national who joined the islamic state group in syria has been found guilty in the united states of hostage—taking and conspiracy related to the murders of four americans in syria. el shafee elsheikh was part of an is militant cell dubbed �*the

happen down the line what would happen down the line and how difficult it would be to ultimately give them a criminal trial. right now we are trying to work around that with things like plea deals,

always enjoyed a very, very good relationship with the united kingdom. what is interesting here though is it has been difficult sometimes working with mostly western european countries, you get some of these folks who have committed crimes against americans criminally tried here and this is the first time, a lot of negotiation took place, the death penalty was taken off the death penalty was taken off the table, which i agree with in this case, and he's been tried here, and that is a huge deal and a huge milestone in cooperation.— cooperation. yeah, really reassuring. _ cooperation. yeah,

during a confrontation. the footage shows patrick lyoya being shot in the back of the head as the two men wrestle after a traffic stop. the protests have remained calm and peaceful, though anger is high. our correspondentjohn sudworth has the story — a warning, his report contains some distressing images. it began as a routine police matter, with 26—year—old patrick lyoya pulled over in his car by a white officer in a michigan suburb. do you have a driver's licence? do you speak english? yes. but what happened next has once again put the question of racialjustice and policing right back in the national spotlight. 1915, we've got one running. as mr lyoya tries to get away, there's a struggle over the police taser before mr lyoya is forced face down to the ground. let go of the taser! and then, as the struggle continues, the police officer draws his gun gunshot ..and fires one fatal shot to the back of the head. at a press conference, his mother and father, who'd fled the war in congo eight years ago, spoke of their anger that their son had been killed by a bullet on the streets of america. i'm asking forjustice. applause i'm asking for justice for patrick. what do we want? justice! protests have already been held over the ten days since the shooting, but now the release of the video has the potential to spark a wider outcry. the officer, whose name has not yet been released, faces an investigation — while america yet again grapples with the questions posed by a police shooting of an unarmed black man. john sudworth, bbc news, washington. new trials aimed at eventually finding a cure for multiple sclerosis have been seeing some positive results. the trials have followed a landmark study into the disease that showed overwhelmingly the link between the common epstein—barr virus — ebv — and multiple sclerosis, an incurable autoimmune disease that affects the central nervous system. we're joined now by the scientist who led that study, alberto ascherio, professor of epidemiology at harvard's th chan school of public health. talk us through this, what is a link between the two, in layman terms as well?— terms as well? thank you for invitin:

sclerosis. this was discovered after following a population over1 million after finding that those with ebv do not develop multiple sclerosis. it is only after infection that they have signs of a degenerative process in the brain and then they develop ms if there is a link between ebv and ms, cannot we just vaccinate against ebv? in theory, there is not enough approved vaccine for ebv but

the city enters its third week of a covid lockdown. 0ur correspondent, robin brant, reports from shanghai. crowd shouts. three weeks into lockdown, some here in shanghai are angry. in broad daylight, a confrontation. the police up against the people. horns honk. woman screams. scenes like this have become increasingly unusual here, but then, so is locking down almost 25 million people. head to toe in protective suits, in an eastern district of the city, officers were forcing people out of their rented apartments so they could turn them into temporary quarantine facilities, all in the name ofa waragainst a resurgent covid. but for some, it was just too much. their homes sequestered, their desperation easy for all to hear. woman cries. a few miles away, there was an organised protest — a bold stand as the lockdown takes hold. in a country where you can be arrested for picking quarrels, they're angry about a local school being turned into another quarantine facility. police with riot shields forced them off the streets in the end. this was on a small scale but it's a sign of anger and frustration as this lockdown goes on. larger scale social unrest is what the ruling communist party fears the most and would likely tolerate the least. robin brant, bbc news, shanghai. lots more on our top story on the war on ukraine including extensive reporting on president volodymyr

a little bit of rain pushing into the far north and west of the uk as we head through easter sunday into easter monday. but i think for many, it will stay fine, dry and pretty warm. temperatures into the low 20s celsius across the warmest part of the south and east of england. we'll have these weather fronts across more western areas, but this high pressure will continue to exert its force and keep them out at bay. so, for good friday, many places will start dry with some sunshine through central and eastern areas. a bit of coastal mist and fog around. further west, closer to those weather fronts, we'll have more cloud — northern ireland, south west scotland, along irish sea coasts down into south west england, the odd shower around here. the odd shower could develop elsewhere as temperatures reach the low 20s across the southeast. most places, though, will be dry, and for many, it's going to be mild with light winds. as we head through friday night, most places will be dry. any showers will die away. we'll see some low cloud, mist and fog returning, particularly across more southern and western areas. for many, it's going to be a mild night, but under clearer skies across the east, could be fairly chilly. so, for saturday, another dry day, plenty of sunshine from the word go across the south—east. after that cool start, temperatures will rise. again, there is a very slim chance of a shower developing here and there. most places will be dry with sunny spells. bit more cloud across the very far west. temperatures, again, mid—to—high teens, low 20s in the warmest spots. now, this is where we start to see a little bit of difference, a little change to the weather through easter sunday into monday. we could start to see our area of high pressure break down. that'll allow low pressure to push in from the west, but pushing weather fronts from west to east. but because these weather fronts will try to bump into this area of high pressure, they will be fizzling as they try to track their way eastwards. i think easter sunday, the very far west of the country looks like it will see some cloud and rain. elsewhere, most of the country will be dry again with plenty of sunshine, and it'll be quite warm with temperatures reaching 20 or 21 degrees. as we move into easter monday, that front clears eastern areas — barely anything on it. slightly fresher day to come for many, with low pressure could be quite windy across northern scotland, one or two showers here. but elsewhere, i think it looks largely fine, dry and settled, with temperatures a little bit lower. this is bbc news. the headlines: volodymyr zelensky�*s criticised eu countries that continue to buy russian oil, saying they're are aiding the country's attack on ukraine. the bbc had an exclusive interview with the ukrainian president inside his war bunker, in which he urged western leaders to speed up the delivery of weapons to ukraine. russia says a warship that was damaged by an explosion on wednesday has sunk. it said moskva, the flagship of russia's black sea fleet, was being towed to port when "stormy seas" caused it to sink. ukraine say they hit the warship with missiles. a former british national who joined the islamic state group in syria has been found guilty of involvement in a series of beheadings, by a court in the us. el shafee elsheikh was part of an
