matches, joe root steps down as the england men's cricket captain. and coming up on the bbc news channel. an incredibly difficult decision according to the burnley chairman, as manager sean dyche is sacked after nearly ten years in charge. good evening. russia has threatened to intensify attacks on the ukrainian capital kyiv if its territory is further targeted. tensions have risen since russia's iconic warship, the moskva, sank yesterday. moscow says the sinking was caused by a fire, but ukraine says it hit the vessel with missiles. a weapons factory near kyiv has already been partially destroyed in a russian attack. our correspondent yogita limaye sent this report. this was the moskva. russia's prized warship in the black sea. it's now sunk. ukraine says its missiles hit the vessel. russia says a fire caused the ship to sink. it's a humiliating loss for the country and believed to be the biggest such incident since world war ii. in what is being seen as retaliation, russia's defence ministry shared this video, saying it had launched an attack on a missile making facility outside ukraine's capital. it also threatened more strikes on kyiv if ukraine continued to attack russian territory. sirens after the relative silence of two weeks since russian forces withdrew from kyiv, air raid sirens continued to ring from night into the morning. yuri lives near the site of the attack. translation: i woke up to the sound of an explosion atjust past 1am. - my house shock like there was an earthquake. then i heard more explosions. the lights went out. i have no electricity or water now. the area around the factory which was hit as a residential neighbourhood. it's quite densely populated. if it is only about a 15 minute drive from here to the city. the attack over night, a reminder ofjust how vulnerable kyiv remains as a target. this city has just begun to come alive. people who were forced underground for weeks when areas around kyiv came under russian control are cautiously coming out for a moment of calm in the sun. translation: you forget sometimes that you're - still afraid of every sound, even if it comes from your neighbour's house, or if someone bangs a car door. you shiver and try to overcome that. no words can describe how scary it is. we can't be sure what will happen next. the future might be worse. the images coming from the east show just how bad things could get. this is the port city of mariupol, believed to be close to falling into russian hands. it's been more than seven weeks of war. yogita limaye, bbc news. the grandmother of a british man, who has been captured in ukraine, says she is horrified by images of him being shown on russia tv, and has called for him to be treated humanely. aiden aslin was fighting with ukrainian forces in the besieged city of mariupol, when he told family he was having to surrender to russian forces. here's our correspondent emma vardy. if you're watching this, it means that we've surrendered. the last words to loved ones from within one of the desperate places on earth. we ran out of ammunition. didn't really have any other choice other than to surrender. for weeks, aiden aslin and his unit defended the heavily—bombarded city of mariupol, holding off russian forces as long as they could. two days ago, his family received a phone call as he explained they were having to surrender. to lay down our arms and head towards the russian soldiers. i knew that the ammunition situation was very low. and they wouldn't have surrendered if they'd still got ammunition. the next time his grandmother and otherfamily members saw him, it was aiden in handcuffs, now a captive, being paraded on russian television. when you see those images, what goes through your mind? i was horrified. absolutely horrified. my heart stopped. his face is swollen, a nasty gash across his forehead. having seen him, i know he's alive but i'm not sure if that's a comfort because i don't know really how he's being treated. unlike many other foreign fighters who have travelled to ukraine, aiden was no newcomer. he'd become a marine in ukrainian military in 2018, was engaged to a local girl, and had made the country his adopted home. his family say they can only hope for a prisoner exchange. but this conflict is also a battle of propaganda, in which it's clear aiden is now being used by russia to play a part. emma vardy, bbc news. more than 150 people have been injured in clashes between palestinian demonstrators and israeli police at the al—aqsa mosque in eastjerusalem. tensions have been high in recent weeks as the fasting month of ramadan coincides with passover forjews, and easterfor christians. police said they entered the mosque to disperse a crowd, after rocks were thrown ontojewish worshippers at the western wall below. here's our middle east correspondent yolande knell. as day broke injerusalem's old city, sacred to three faiths, tensions were rising at its most bitterly contested site. israeli police say they moved in to disperse a riot by palestinian muslims at al—aqsa mosque. officers fired stun grenades and rubber bullets. palestinians threw stones and firecrackers. the violence came inside the doors of the mosque. it takes hours for a fragile calm to set in, and we meet omarjoining the clean up. he came for ramadan prayers. you just want to pray. and it's really heartbreaking to see one of your holy sites, like 80 kilometres away, just to get this type of behaviour against you. i'm speechless. nearby, it's a special day for christians. thousands have come for easter and to walk the traditional way of the cross. it's incredible. it's a miracle to be here and to share this holy friday with all the people and to pray for everybody. we pray here for the peace. but for now, those prayers aren't answered. the overlapping religious holidays were always going to raise tensions here in the old city. people of different faiths are celebrating, but these narrow streets feel more on edge after the recent deadly violence and today's clashes. elsewhere in jerusalem, a jewish ritual. families are burning the bread, banned during passover, which begins tonight. elana says the holiday�*s overshadowed by attacks in israel, which have killed ia people. you can't help thinking what will be the passover experience of those families who weren't expecting to have one person less at their table? and it's really a national pain. this should be a joyful time for palestinians and israelis, but instead it's an uneasy one. the lesson from history is that confrontations which start inside these ancient walls can easily slide into a wider conflict. yolande knell, bbc news, jerusalem. it's been the hottest day of the year so far, and roads and railways have been busy as millions of people try to get away for an easter break. the good weather resulted in delays in south and south west england, as motorists headed for the coast, or tried to travel via the port of dover. and there's major disruption on some rail lines because of bank holiday engineering works — there are no trains at all in or out of london's euston station. tim muffett has the latest. the long weekend. with queues to match. we are a little bit worried about traffic. that's why we came very early. it's easter weekend, the perfect storm, isn't it? exactly what you don't want it to be. in dover, just as holiday—makers are leaving, p&0 has suspended its ferry services. post—brexit lorry checks are also said to be adding to the challenge. it's the first bank holiday since all covid travel restrictions were lifted in the uk. the rac estimates more than 22 million carjourneys will take place this weekend. the message clearly is plan your trip well in advance, make sure your car is ready for a journey as well. in lots of cases, this is the first long—distance trip people have taken this year. at woolley edge services in west yorkshire, for many motorists, the heavy traffic was worth it. had a long—planned celebration of my husband's 80th birthday, so we are gathering in sheffield. my family said it has to be easter because the children are off school and we're off work. just a hassle at the - airport at the moment. i'd rather... i don't know now. stick on the motorway or get stuck in manchester airport. _ i think this is the lesser evil. despite recent disruption, queues at manchester airport were said today to be moving steadily. but on what has been the hottest day of the year so far, some rail services have been disrupted. london's euston station is closed all weekend, as is the west coast main line between london and milton keynes. now that could pose a challenge for liverpool and manchester city fans planning to travel to wembley tomorrow for their fa cup semifinal. the work has to be done at some time. adam has multiple sclerosis and has decided not to travel to the match. at the start of the season, most sensible people will have said two of the best teams in the country are liverpool and manchester city. so there was a fairly good chance that one, if not both, of those teams would get into the fa cup semifinal. the fa cup semifinal is pretty much always this weekend and yet there's all these rail works going on. network rail says 95% of its services will be unaffected by planned engineering work this weekend. as ever, the advice is to check yourjourney before you set off. tim muffett, bbc news. it's been confirmed that the duke and duchess of sussex met the queen at windsor yesterday, afterflying into the uk. prince harry and meghan are now in the hague, in the netherlands, for the start of the invictus games. the couple hadn't been in the uk together since they stepped down as senior royals more than two years ago. brain tumours are the most common fatal cancer in people under a0. the issue was highlighted recently when the singer tom parker from the band the wanted died at the age ofjust 33. but treatments and research into the condition has been limited in comparison to many other cancers. now, patients at addenbrooke's hospital in cambridge are having the entire genetic code of their cancers sequenced, as part of a research project. it's hoped that tumour mapping will lead to more accurate diagnosis, and perhaps eventually to personalised treatment. just to warn you, this report from our medical editor fergus walsh contains pictures of brain surgery. i've got a rough idea of what's going to happen. i'm going to be partially awake, but i'm going to be woken up during the surgery. daniel is just 34. he's on his way to theatre for brain surgery. i think that's the bit i most scared about, being awake and having someone screwing around in my head. daniel has a large brain tumour — the round, white area at the top of this scan. 0k, starting. to begin with, daniel is fully anaesthetised, while surgeons remove part of his skull. but once his brain is exposed, he is woken up and must be kept awake. daniel, how are you feeling? yeah, good. excellent. we just need to be a bit careful at the back, because that's close to where the part of your brain that moves the right—hand side of your body is. before removing each piece of tumour, surgeons need to be sure it won't affect daniel's speech or his ability to move his body. i'm going to show you some pictures now, dan, 0k? - i want you to just say what you see. so at each step, the team checks his responses. light bulb. well done, dan. part of daniel's tumour will be sent for whole genome sequencing. its entire dna will be mapped. what that means is, essentially, we are looking at the abnormalities in the genes that we think caused the tumour in the first place. so, we are really able to drill down into the molecular problems in the tumour. daniel's diagnosis, his future, rests on what they find in these tubes. dna sequencing used to take months. now it can be done in days at these labs near cambridge, of us biotech illumina. not only does it speed up diagnoses, but reveals what is driving the growth of a patient�*s cancer. because this is low—grade... just two weeks after surgery, daniel returns to addenbrooke's with his brother, to receive his results. this is a diagnosis that is treatable. but it's not a curable condition, 0k? so this is something that will be life limiting. about 50% of people survive for 15 years or more. but i think it's important that you understand that this isn't something that is going to go away. wow. i don't know what to say. sure. — you don't have to say anything. enjoy the next 15 years of my life. he's gone 2—0 to them. a few weeks later, ijoined daniel to watch his local football team. the quality of finishing is shocking. he used to play in goal. now he gives advice from the touchline. life's very short. so, i want to make the most of it. i just want to get the treatment i can, to prolong my life. six weeks of radiotherapy, five days a week. more than 200 brain tumour patients are taking part in the research, with the hope it may eventually yield new, personalised treatments which improve outcomes. fergus walsh, bbc news, cambridge. in football, burnley have sacked their manager sean dyche withjust eight games of the season to go. dyche was the premier league's longest serving manager, having joined the club in 2012. he leaves with burnley in the relegation zone and four points from safety. joe root has stepped down as the england men's test cricket captain, after five years. his position had been in doubt since a humiliating 4—0 drubbing in the ashes, followed by defeat at the hands of the west indies. root has the record for the number of test series as captain but has secured only one victory in the last 17 matches. patrick gearey reports. sometimes you don't need scores or even words. just a face. this was joe root at the end of england's series defeat to west indies last month, theirfourth in a row. and that would prove to be the end of his captaincy. this morning, a statement marked the close of a five year innings. root said, i have loved to leading my country, but recently it's hit home how much of a toll it's taken me and the impact it's had on me away from the game." eventually, you do start to realise that, however passionate you might be about the job, it's one of those jobs that does grab you, you never really want to give it up, no matter how bad things are. one of the things you have to say is that it's a results—driven game. if you're not getting wins, which is what basically has been happening for the last 12 months, at some stage something has to change. joe root has long been england's anchor. the outstanding batter of his generation. that is another magnificent 100 for root. ajump and a skip forjoy. he'd never been a permanent county captain when he was chosen to lead his country in 2017. a fresh and cheerful face to take the team forward. he'd captained england for more tests than anyone else in history, and win more matches, too. when lockdown forced the squad into bio—secure bubbles, root led them through it. but this would be as close as he got to the ashes. his england team were unable to win any of the three series they played against australia. their most recent defeat came as part of a run of one win in 17 tests. nevertheless, root thought he could see a path through. i'm still very passionate about taking this team forward. i feel like there is the support of the dressing room behind me. and, you know, i'm desperate to turn that round. it wasn't to be, but he will carry on in the team. those who run english cricket talk of a reset. that's meant the off switch for the managing director, coach, and now the captain. all three jobs remain unfilled. you have to say that english cricket, at the moment, is in a real void, there is a vacuum there. and the people who will appoint joe root�*s successor haven't themselves been appointed yet. so, it's a pretty crazy situation. so, who is in next? well, maybe england will send for their superman, ben stokes. he's a world—class all—rounder, but has taken time away from the game recently to look after his mental health. and as root�*s friend, he'll knowjust what is involved in one of english sport's most stressful jobs. patrick gearey, bbc news that's all from the bbc news at six, and on bbc one we nowjoin the bbc�*s news teams where you are.
