russia has formally warned the united states and its allies against supplying further weapons to ukraine. the kremlin said, the arms shipments could lead to what it called, unpredictable consequences. speaking during an interview, president zelensky has acknowledged that up to 3,000 ukrainian soldiers have died — and as many as 10,000 have been left injured since russia invaded his country in february. meanwhile, the head of the un's world food program has said he's not getting a response from moscow about how to reach people starving to death in besieged parts of ukraine, including the city of mariupol. and in the latest developments — there have been reports of new strikes on the outskirts of the ukrainian capital, kyiv and explosions have also been heard in the western city of lviv. the russian foreign ministry has said that it's banning the british prime minister, borisjohnson and other senior ministers from entering russia, over the uk's hostile stance on the war in ukraine. danjohnson has this report. russia threatened more attacks and they seem to be coming. a missile factory was hit yesterday and there were more explosions on the edge of the capital early this morning. emergency teams are responding there. sirens. further west there was another air—raid alert in lviv. 0fficials here say two russian jets attacked the city last night having flown from belarus. apparently four missiles were fired but they were shot down by ukrainian air defences. it is a reminder of the threat here, even hundreds of miles away from the front line fighting in the east. kharkiv has been under intense shelling. as forces build up in the expectation of more fighting. it is the lives and homes of ordinary people that are caught in the crossfire. vladimir putin has warned other nations supplying ukraine with weapons would fuel the conflict and risk unpredictable consequences. the ukrainian president sees it differently. translation: the more and the sooner we get all the weapons we have requested, the stronger our position will be and the sooner there will be peace. mariupol still sees intense fighting. russia has said it has taken a steelworks. which was battled over for days. ukraine claims it has held off russian attempts to finally take the city. every day more evidence is uncovered of what people suffered during the russian occupation. the un has recorded over 1900 civilian deaths since the invasion and it says the true number will be higher and more are dying every day. danjohnson, bbc news, lviv. jakob kern is ukraine emergency coordinator at the world food programme. hejoins me from lviv. thank you for breaking off from all the work you and your colleagues are doing to speak about this. what would you describe as the current situation in the country? presumably, it varies quite a lot across what is a vast place. we have two distinct — across what is a vast place. we have two distinct areas, _ across what is a vast place. we have

took ten years took —— in syria, it took ten years to get to these numbers so you can imagine how big the humanitarian needs are in there is something almost perverse about being in a country that has been described as the breadbasket of the world, and has fed millions, and yet now people are literally starving to death. we mentioned that you are ahead of the world food programme, saying russia isn't providing them with information and access to get to these people, what do you understand to be the situation in mariupol at the moment?— to be the situation in mariupol at the moment? ~ ., , .,

gas, nothing to cook. but also medicine. if you need medicine for chronic illness or the common flu, can turn into a life—threatening situation if you cannot go to the pharmacy and buy antibiotics or by your diabetes medicine. so, it is notjust food, it is everything, and these people are probably living underground because they are being exposed to shelling. and we have seen the same in syria, i was there four years ago during the war, a similar situation, besieged cities that are suffering tremendously. it is besieged cities that are suffering tremendously.— besieged cities that are

agreement from both sides to have a ceasefire, or at least 48 hours to get food and medicine in safely and get the supplies back out, the people that supply those trucks, to get out. but if you take a city of 500,000 people, you would need five trucks a day of just food people, you would need five trucks a day ofjust food to go in, and we haven't had access since the war started. we haven't had access to any of those cities. it is terrifying _ any of those cities. it is terrifying to _ any of those cities. it is terrifying to imagine i any of those cities. it is i terrifying to imagine what

some sense of the problem is that you see further down the line if this war persists. because this is a country that has a very thriving agricultural sector, presumably most of that is not functional at the moment? well, i was in kyiv — functional at the moment? well, i was in kyiv last — functional at the moment? well, i was in kyiv last week, _ functional at the moment? well, i was in kyiv last

550 kilometres is agricultural land, it is planting season, people are actually planting maize, barley, sunflower, and the winter wheat is starting to grow. this is a place which is the fifth largest producer of sunflower oil and seeds, maize, barley, and it is heartbreaking to see that the farmers are still planting, even though they will not know how to get the wheat harvested because ukraine is not able to export. so, further down the line, we will not have only the price increase that you see already everywhere, wheat prices have gone up 25%, but you also see shortages of sunflower oil and wheat. the world food programme is buying half of its wheat globally in ukraine, orwas buying half of its wheat globally in ukraine, or was buying half of it. that is 800,000 tonnes. we have to buy now elsewhere, and that cost us 70 million more a month, $70 million a month, we could feed 4 million people, and that is a direct effect to the world food programme. 50. people, and that is a direct

so, you could end up in a nightmare _ could end up in a nightmare situation if the war continues and nothing changes, when you have a glut and high prices but that that is food that spoils because nobody is food that spoils because nobody is in a position to store it or distribute it and get it to people who meanwhile are starving elsewhere in the country?— in the country? that's correct. the

— water levels are still dangerously high in parts of kwazulu—natal in south africa, after devasting floods earlier this week. people have been urged to move away from low—lying areas, but many have nowhere else to go. more than 400 people have died in the floods and at least 13,000 homes damaged. thousands of survivors are living in shelters across durban, after the deadliest storms to strike the coastal city in living memory. pumza fihlani reports. so, we are in an area that is north of durban, one of the worst affected townships in the city. just behind me, there is a big gash in the road and that is just indicative of some of the destruction that is happening in some of these communities where bridges have been washed away and roads have been completely destroyed, cutting off communities. it has also meant that it has been difficult for people on that side of the road to get the help that they need. we also now understand that reinforcements have arrived from other provinces to try and help with search efforts and rescue efforts as well as trying to retrieve what is an estimated 20 bodies that are trapped under mud slides and they are hoping that once that is done, those bodies will be handed over to the families. i am watching a woman behind you, very gingerly, trying to descend down from the roadside. she has got her shopping bag, i guess she has got to get out of the house, but it is pretty risky in lots of areas and there is a warning of more rain on its way. the combination of how things are at the moment, the fact that the waters are still quite high, presumably, and now fresh rainfall, authorities must be really worried about this? yes, they certainly are, they have issued a warning and plea to people to try and move to higher ground, but for many people that we have spoken to, they have said that this is impossible, because they have lost everything that they have and currently they have got nowhere else to go to. the woman that you mentioned, she walked past here, she needs to get across and this is one of the only ways that she can get there and really, for the people here, they have told us how desperate they are and they are hoping that the government will speed up efforts to try and get reinforcements to them. we have spoken to people who have said they have not had clean water since monday, others have not had power and also there are food shortages across various parts of the province. it's emerged that the uk government formally instructed civil servants to press ahead with an overhaul of the asylum system before they could estimate how much money would be saved by the scheme. the home secretary, priti patel, had to personally approve the policy — which could see immigrants who've arrived in the uk unofficially flown to rwanda. 0pposition parties have condemned the proposals. i've been speaking to our political correspondent, jonathan blake. this particular mechanism was used, and ministerial directive as it is called, is only used relative really rarely. for the home office this is only the second time has been used in 30 years but it does not mean there is an objection in principle, officials are not saying it will not work and we won't do it but in this case it was about cost. officials were unable to specify how much this would cost in the long—term and say if it would represent value for money for the taxpayers. officials were unable to specify how much this would cost in the long—term and say if it would represent value for money for the taxpayers. because of that there was an objection and the home secretary had to say we will disregard that and go ahead anyway and that is why we have ended up where we are. the policy itself which was announced a few days ago, we can see pictures of priti patel in rwanda and signing this deal, it has been quite controversial in the uk. to say the least, there is in a chorus of criticism from opposition as you might expect who call it unworkable, unethical and inhumane but there is also more criticism from unions representing civil service staff, officials working in the home office and other departments which echo a lot of that and also pointing out that staff will face a choice over what they describe as a divisive policy, whether they are going to remain and or seek to move their post and moved to different alien government or leave the civil service altogether which gives concern about how workable and appropriate this policy is. one of the uk's most senior criminal lawyers has called for the post office to be stripped of its power to bring private prosecutions. the public inquiry into the treatment of former sub—postmasters draws to a close next month. the post office used its power to bring private prosecutions to take more than 700 branch managers straight to court. because of faulty software, money appeared to be missing from their branches. 0ur correspondent colletta smith has the story. i don't get it. i really don't get it. most of us were aware then, obviously, that horizon was having its issues, but then they still chose to prosecute me! and that is just malicious, nasty. pauline was sacked, made homeless and given a criminal conviction when her youngest daughter was only two. the computer system had shown a shortfall at her branch. she'd asked for help, but instead, the post office sent in their team of investigators. considering they're not the police, but they made you.... they made you feel like they were the police. what got me was the way they went about it. it was... it was, it was... they were so aggressive. the same happened to marion's husband, peter, and more than 700 others investigated and taken to court, not by police, but by their employer. the problem with the post office, or the problem from our point of view, with the post office is they do all their own prosecution, so basically, they were judge, jury and executioner. the subpostmasters have been on the back foot from the very beginning because the post office held all the information and, crucially, rather than the police, it was the post office who investigated and then brought the prosecutions. but testimonies at the inquiry have shown big problems with the way post office investigators treated subpostmasters. i felt humiliated, scared to death. tony edwards is one of the uk's most senior criminal lawyers and has spent decades training the police how to carry out investigations fairly. the post office should have followed those same rules. those investigators either didn't know or chose not to observe i the rules about making clearj that people were not obliged to do anything. they were free to go. we all were made out to believe we were the only ones. everybody was told no—one else has got a problem, must be you. the lie that you are the only one saying horizon is to blame i is entirely undermining. and there must have been a point very early on when post office i investigators knew it was not true. peter died in 2015, but it took marion another six years to clear his name. the post office say victims�* testimonies have reinforced their determination to ensure that wrongs of the past are put right. but marion is hoping the next stages of this public inquiry will hold post office bosses to account for the treatment peter received. colletta smith, bbc news, in leeds. the duke and duchess of sussex are both due to speak at the opening of the invictus games in the netherlands on saturday evening. they arrived in the hague on friday after stopping off to visit the queen in windsor near london. it's the first time prince harry and meghan have appeared in europe in public together since stepping back as senior royals in 2020. prince harry founded the event to aid the rehabilitation of injured military personnel and veterans from around the world. let's talk to our correspondent at the hague, anna holligan. is there much interest? from the dutch public in harry and megan? are they celebrities, rather than royals, or is there still a residual respect for them because they are european royals? aha, respect for them because they are european royals?— european royals? a bit of both, actuall , european royals? a bit of both, actually. and — european royals? a bit of both, actually, and if _ european royals? a bit of both, actually, and if there _ european royals? a bit of both, actually, and if there is - european royals? a bit of both, i actually, and if there is anywhere in the world where harry and megan can expect a warm welcome, it is here at invictus, because harry created these games. i have just survived a drive around this track, they were driven around in miniature cars who by two young girls did very well to keep their cool, and absolutely, among the crowd they are, they are celebrities and they are, they are celebrities and they are royals, of course they had stepped down as reckoned royals, but all around the site, in a southern suburb of the hague, they have stepped up security, there are police around the periphery, there are fences, and the reason people are fences, and the reason people are gathered here is because there has just been a driving challenge behind us before the children drove them round the track. prince harry was in the front of the car, going over a kind of assault course and then he and megan were back together again. there has certainly been a touch of hollywood here but really this is about all the competitors and speaking to them, it is fascinating because it is winded and serving military personnel, and so many of them credit invictus with being such a huge part of their rehabilitation, giving them something to aim for, to work towards, and of course because harry has experience in the military, they really, really feel a connection there. , . really, really feel a connection there. . , , there. dutch troops, presumably, were obviously _ there. dutch troops, presumably, were obviously also _ there. dutch troops, presumably, were obviously also part - there. dutch troops, presumably, were obviously also part of - were obviously also part of afghanistan and the rest of it, there are lots of reason while —— why competitors, in a sad way, this has become more important now than maybe it has been for 20 or 30 years, the opportunities for former service people who have disabilities to compete in sport, how big an event has this become?- to compete in sport, how big an event has this become? huge. you talk about veterans _ event has this become? huge. you talk about veterans and _ event has this become? huge. you talk about veterans and this - event has this become? huge. you talk about veterans and this is i event has this become? huge. you talk about veterans and this is also j talk about veterans and this is also about serving personnel, and in fact, last night, when harry and meghan arrived here, they were cheers for team ukraine who had an audience with the royals. they actually lost four members of the invictus family, ukraine did to in rocket attacks and two in combat, so it has very much back how much this whole event means to the people who are able to take part. i spoke to one veteran who was injured in afghanistan and they all have different stories but what they say that coming here gives them something to look forward to, a chance to put back on their team colours, to represent their country again, and that, specialfor parents who have lost limbs, can show their children they are now competing again at the top of their game. this isn't so much about meeting —— winning medals, this condition is that, chip and the chance to work together, for recovery and rehabilitation, so although the medals are being given, the first event has just taken place, the opening ceremony taking place later, harry and meghan will speak, it is really all about the atmosphere and the spring the summer sunshine that everyone is coming together here today to enjoy. everyone is coming together here today to enjoy-— everyone is coming together here today to enjoy. today to en'oy. anna holligan in the hauue, today to enjoy. anna holligan in the hague. thank— today to enjoy. anna holligan in the hague. thank you — today to enjoy. anna holligan in the hague, thank you very _ today to enjoy. anna holligan in the hague, thank you very much. i the us state department says it's deeply concerned by the level of violence in jerusalem, after clashes yesterday, between palestinian demonstrators and israeli police. more than 150 palestinians have been injured in clashes with israeli police at the al—aqsa mosque, in occupied eastjerusalem. three israeli police officers were also hurt. tensions have been high in recent weeks, as the fasting month of ramadan coincides with passover forjewish people — and easter for christians. let's return to the story that the british government had to issue a directive because civil servants were worried that they can calculate the financial benefits and diss benefits of the new policy potentially sending asylum seekers for processing to rewind in africa. simonjones is at the port of dover on the east coast of kent. that coast line is a place where many migrants vessels pitch up, many people in small inflatables, small boats, having come overfrom continental europe, as part of their journey from their home countries. is there any sign at all, and perhaps it is far too soon since they only now is this policy midweek, but there is any sign of talk that it may be acting as a deterrent yet? i talk that it may be acting as a deterrent yet?— talk that it may be acting as a deterrent yet? i think no sign at all at the moment _ deterrent yet? i think no sign at all at the moment because i deterrent yet? i think no sign at all at the moment because the l all at the moment because the crossings have continued today. earlier in the day, it was actually pretty chubby in the channel, the wind got up, but then when the wind dropped and it was calmer, we saw several boats of migrants being brought to short here in dover by the rnli and also by the border force. among the people arriving were several babies, we also saw women and children, although the vast majority arriving were men. now, in terms of the numbers today, i am being told it is possibly around 250 people already today. yesterday, we have been told by the minister of defence who have now taken operational control in the channel that 181 people made the crossing on six boats. that is more than 30 people per boat on average so it gives you an idea of the type of boats we are talking about. we took that small boats but they are jam—packed full of people and although this policy was announced earlier this week, potentially sending people who make this crossing to rwanda on a one—way ticket, i think music that is spreading over in the camps in calais, from which many that people begin this journey across the channel. although, they will have travelled across europe from over many different countries before arriving in france and ultimately getting to the uk, but what we are not clear is when exactly the government will try to start moving people from here 4000 miles away to rwanda. they have said they want to potentially start within six weeks but it is legally complicated, the government expect there to be weak legal challenges. and also there is a real degree of opposition. we have heard opposition from opposition parties here in the uk. we are also hearing from the pcs union who represents civil service staff who talk about policy being inhumane, and also, as you mentioned at the start, priti patel, the home secretary, had to order that directive, basically there were concerns raised amongst civil service at the home office about just how much this would cost, when it it would be value for money but she says she will take personal responsibility, she was to plough ahead with this, i understand it is difficult at the moment, the government feel, to qualify had just how much all this will cost but they feel it will be value for money. and if it does act as deterrent, they think that will be well spent. simon jones on the _ think that will be well spent. simon jones on the kent _ think that will be well spent. simon jones on the kent coast _ think that will be well spent. simon jones on the kent coast in - think that will be well spent. simon jones on the kent coast in dover, i jones on the kent coast in dover, thank you. the world renowned pianist lang lang has been hitting the high notes during a performance that could give you goosebumps. was playing at europe's highest train station in the swiss alps. a grand piano was taken to the mountaintop 3,400 feet above sea level. he said it was his first performance in the snow but that he really enjoyed the experence. do you think your fingers feel heavier up there? i wonder. we have got some great weather this easter weekend. temperatures have so far got up to 23 celsius in the south—east of england, that was yesterday, not quite as warm today but warm enough. high pressure in charge of the weather but a weather front is approaching. you can see it here in the satellite picture, this area of cloud, that is approaching northern ireland. ahead of it, already skies are hazy in western parts of the uk. so not sunny everywhere. one thing worth mentioning, the pollen, high tree pollen levels for england and wales for today and tomorrow. in scotland and northern ireland, they are not quite as high. the temperatures by the end of the afternoon will have reached the high teens in the midlands but fresher in eastern scotland. here is the forecast for tonight, fine weather across the bulk of the uk but here is that weather front unfortunately, whether you like it or not, approaching northern ireland bringing cloud and rain by the early hours of sunday morning, especially to western parts of northern ireland, elsewhere we are in for a dry and sunny start to the day, sunshine from the word go for many parts of the uk for easter sunday. a different story for the west. a slow—moving weather front which should reach belfast by the afternoon, so a lot cooler here. only 13 degrees, with the rest of the country typically around 15—20 c. that weather front will make further progress across the uk by monday, you can see it here along the spine of the country. around it, cooler air from the atlantic which means the temperatures will start to ease from monday onwards. so low pressure to the north—west, a stronger breeze for northern ireland and scotland, showers for sure and probably one or two showers elsewhere across england and wales but lengthy sunny spells as well. temperatures already much lower, 12 in glasgow, 13 in liverpool, no higher than 17 in london, decent enough for the time of year. here is the outlook for the week ahead, you can see temperatures easing but stabilising around the mid teens in the south, typically 12 in the north. bye— bye. this is bbc world news, the headlines... russia has formally warned
