is its this is bbc news 7 welcome if you re watching here in the uk or around the globe. i'm rich preston. our top stories. president biden meets ukrainian refugees in poland, before delivering a stark warning to russia's vladimir putin. don't even think about moving on one single inch of nato territory. as the president prepared to speak, russian missiles hit a fuel depot in lviv, close to the polish border. as fears grow of hidden spies and saboteurs within ukraine itself, we have a special report from the city of odesa. tributes from across the music industry for taylor hawkins, the drummer with the rock band foo fighters, who's died at the age of 50. and prince william

and kate mark the end of their week—long tour of the caribbean, with the prince saying he's learnt a lot from the people he's met. hello. the western ukrainian city of lviv has been largely untouched by the fighting in the country — until saturday. the war arrived with russian missiles striking close to the city centre — hitting an oil storage depot. lviv is not far from the border with poland, where the us presidentjoe biden delivered a major speech — saying the russian leader vladimir putin, "cannot remain in power." mr biden said the battle between democracy and dictatorship is "the fight of our generation" and warned mr putin not to even think of attacking an "inch of nato territory." our first report is from our

north america editor, sarah smith, who is travelling with the president. this is notjust ceremony as the presidents of the us and poland marched in step together, but a declaration of intent that america would do everything it takes to defend poland from what they see as a great threat from russia. visiting some of the more than two million refugees that have fled from ukraine into poland, he praised the bravery and announced that vladimir putin as a butcher. we are dealing every day with vladimir putin. look at what he has done to these people. what does that make you think? he is a butcher. tonight thousands gathered to hear an impassioned speech in which biden warned putin... don't even think about moving on one inch of nato territory. we have a sacred obligation under article five to defend each and every inch

of nato territory. with the full force of our collective power. he said talks with russia before the invasion failed because putin was bent on violence from the start, but did not expect such a united response from nato or tough resistance from ukraine. rather than breaking ukrainian resolve, these tactics have strengthened the resolve and the west is now stronger and more united than ever. russia wanted less of a nato presence on its border, but now he has a stronger presence, a larger presence of over 100,000 american troops along with all the other members of nato. he also spoke directly to the russian people saying they are not the enemy. this war is not worthy of you, the russian people. putin can and must end this war. the american people stand with you and the brave citizens of ukraine who want peace.

the speech ended with an unscripted remark that sounded like a call for putin to be removed. for god's sake, this man cannot remain in power. the white house clarified, he was not talking about regime change but that putin cannot be allowed to exercise power over his neighbours. president biden said the war in ukraine is the test of our generation. as he warned the west that they must commit to the fight for the long haul, saying it will not be easy and there will be a cost, but he declared, ukraine will never be a victory for russia. sarah smith, bbc news, warsaw. more now on that russian attack in lviv. several explosions rocked the city, with air sirens ringing out and people told to head to the shelters. russian missiles hit a fuel storage depot, injuring five people. lucy williamson has been to the scene. ukraine's city of refuge has been waiting for one arrival.

today, it came. missiles puncturing lviv�*s sense of safety. explosions emptying its streets. among the infrastructure targeted, this fuel storage depot where five people were injured. marianna heard the explosions from the bomb shelter where she was hiding. "how do we defend ourselves," she demanded. "we had a life before the war started, and now it's not a life, we are just existing." there have been strikes on military targets in this region before, but something changed here today. the sites this time were within the city of lviv itself. the fuel depot less than two miles from the city centre, surrounded by cafes and residential homes. this conflict has been creeping closer to lviv for weeks now. the targets are still military and strategic sites. but this one is right in the centre of lviv.

max heard the explosions from his home in the hills that divide lviv. i lived in the most peaceful city of ukraine. we had some plans for life, to travel, to buy some flat, to have a child. and i don't know when my life might be normal again. location has always been lviv�*s mantra of protection. too far west to really matter in this war. its role instead, to offer sanctuary and refuge. many here tonight are still clinging to that thought. lucy williamson, bbc news, lviv. around the capital kyiv, russian forces are still being kept at bay by strong and determined ukrainian resistance. 0n the frontline are villages, where ukrainian troops have their defensive positions.

jeremy bowen reports from one village which has been battered by artillery and cluster munitions just a kilometre from the russian lines. the russians released these pictures of a cruise missile launch from the black sea fleet. a reminder that they have a lot of firepower left. in the almost deserted villages between kyiv and the russians, reminders are not necessary. they've been battered. this is a village about an hour's drive west of kyiv. the ukrainians claim they have the russians on the run here. it didn't feel like that. these are the remains of russian cluster munitions dropped on friday evening. why are they hitting you here? because here many ukrainian warriors.

and this is line of front, forefront. how far are the russians from here? 0ne kilometre from here. russian warriors, one kilometre from here. civilian houses were hit. so many residents have left that they said there were no casualties. kate and herfamily had only gone as far as kiev. i can say with pride that i am ukrainian. my mother, father are ukrainians. and ijust don't understand why we should go somewhere, why we should leave our houses. a short walk away, someone else's home was destroyed. the owners don't have anything to come back to. the neighbours were fixing their house. volodymir said the russians were responding to ukrainian shelling.

but he said, "our guys won't leave until they drive the russians away." ukrainian resistance derailed russia's plans. but claims they are being forced to retreat around here are premature. you can still feel some of the heat from the fire caused by the missile that hit this house. it doesn't feel at all as if anything is settled around here. i'd be very cautious about assuming that simply because the russians say they will concentrate more on eastern ukraine, that their business around the capital is finished. they were prosperous here before the invasion, with a riding school stabling a0 horses. when this horse was wounded in an attack earlier in the month, the man

who looked after it was killed. smaller incidents don't make headlines but take lives, and change them. jeremy bowen, bbc news, kyiv. russian losses in ukraine continue to grow. it's just over four weeks since the start of the invasion, and a seventh russian general is reported to have been killed. the news comes after another commander was killed by his own troops, angry at the scale of losses incurred by the brigade. so what is the current state of morale of the russian troops? malcolm davis, senior analyst at the australian strategic policy institute gave me his assessment. i think firstly they are seeing they went in with many of the troops not being told exactly what they were doing or where they were going, to fight ukraine. secondly, they go in and they get heavy casualties because of

the incompetent way the war is being run, where the russians apparently have thrown out everything they have learned in past conflicts and they are trying to run this war as if there is no opposition, and clearly that is not the case. so it's entirely understandable that russian troops are essentially blaming their own generals and morale is rock bottom. the suggestion now they are somehow going to pull back and focus purely on the donbas, that will not help morale either. you mentioned some soldiers perhaps had not been given the full picture, and we mention the commander killed by his own troops. what do we know about the russian soldiers�* mentality moving forward? up until this war, we assume the russians were like a serious military threat. we saw the sort

of military tactics and capabilities they used in syria, which the russians used as a battle lab for modernisation. they seemed to be surging ahead with new types of capabilities that were increasingly threatening to nato. now we see essentially this amateur hour approach to the war being run by the russians. and i think it goes to the senior leadership, the lack of effective ncos in the russian organisational structure. the poor logistical support, a lack of control of the air. and you have to wonder, are the russians really ten feet tall or are they a two foot tall pygmy? with the question of nuclear weapons aside, at a conventional level at least, the russians have not covered themselves in glory, and the morale is sure to be rock bottom. russia says it is starting to focus efforts on the east of the country, but it has also attacked lviv in the west.

mixed messages. does russia have a strategy? i think they probably recognise they can't capture the major cities quickly, so they are going to stop that effort and they are going to dig in. 0bviously they are going to focus very much on the donbas to secure that, but i don't think we should assume that is it for the war in terms of the rest of ukraine. the attack on lviv and the west of ukraine are indicative of that. the russians will seek to defend against ukrainian counter attacks, build up the logistical base and build and build up the material war stocks again. when the weather improves, given that it is the muddy season in ukraine, the russians may start a second counter offensive, and that is what we need to be worried about as we go into the spring and summer. while the focus of russia's

invasion of ukraine has been on the frontline fighting and russian bombardments, ukrainians are also worrying about another threat — russian spies and saboteurs, trying to weaken the country from the inside. a month into the war, fear and suspicion loom large, as andrew harding reports from the southern city of 0desa. siren wails. nightfall in 0desa. the wail of an air raid siren. and in thousands of homes here, the dread. notjust of russian bombs, but of russian saboteurs. maybe even next door. a few nights ago, the police came to bogdan milko�*s small apartment. his neighbours had reported seeing a flashing red light. maybe a signal to russian aircraft. "it was my neighbours," he says. "they are scared about security. "i had to go to the police station and explain that i'm just a normal guy, i'm not trying to help the russians."

as we leave his apartment, a crowd suddenly gathers around us in the dark, demanding to see our documents. "we have children," she says. "we don't want a bomb dropping here." well, that gives you a flavour of the fears here in 0desa. people really very suspicious of us, of anybody out of the ordinary. a woman there saying, "who knows who you were, you could have been russians." and those fears are being fuelled by footage like this. of ukrainian police arresting alleged saboteurs. groups sent to plant weapons, or identify targets. this is not paranoia, says captain vladimir karina, there are russian agents and citizens of ukraine working against us. that's a fact. they are trying to distract us, to make us pay attention to the wrong places. the result is a constant wariness, a nation looking

over its shoulder. hunting for signs. like this recent footage of shells fired from russian ships landing just off 0desa. locals patrolling the shore believe the enemy has been getting directions. it was on the roof of this building. a big light, shining out to sea? shining, yes. a suspicious light. and you think that was a signal for the russians? yes, i think it was a signal for the russians. some kind of signal. and now it's almost curfew time again. the streets empty. and as in every war, fear stoking suspicion, prompting vigilance. andrew harding, bbc news, 0desa. this is bbc news. our main headlines. president biden has met ukrainian refugees in poland, and gave a speech warning russia's vladimir putin nato would defend itself, if attacked.

as the president prepared to speak, russian missiles hit a fuel depot in lviv, close to the polish border. 0nto other news now, and authorities in shanghai say the city is too important to the national and world economy to go into full covid lockdown. the statement suggests china may be ready to abandon its zero—covid strategy, despite a rising number of infections. shanghai recorded more than 2,000 new cases on saturday. china has repeatedly locked down entire towns and cities following the discovery ofjust a few infections. but in shanghai, officials are closing down only affected neighbourhoods and relying on self—testing. earlier, i asked dr xi chen, an expert in health policy at yale university, if he thought this would change china's covid policy.

clearly it is becoming more transmissible and less lethal now, people clearly have strong covid fatigue in the fight against covid, so as the virus has spread to most of china... in my view, the current outbreak will not fundamentally change the dynamic of zero covid. china will most likely adjust the stringency of the policy in certain metropolitan, and to have universal testing and perhaps... to eventually get the transmission under control. clearly this will be an uphill battle, especially for understaffed health facilities located in those underdeveloped areas in china. it will take more time this time to get the virus under control and will incur more social costs, for sure.

china has to buy time to optimise the vaccination strategy and be better prepared. you mentioned the fatigue in china with their zero covid policy. are people ready to move forward with more of a living with covid strategy? yeah, the general public, the health officials, i don't think they have psychologically prepared for a major shift in zero covid. the return from the heavy—handed zero covid policy to living with the virus is a salient shift for public health, the official message, and the public health education to learn from the success and failures of other countries, then to learn how to incorporate that into china. but i don't think this is well prepared, because in the past two years, you have seen

in the chinese media lots of news about health crises outside china. so a lot of the general public believe there should be zero casualty and very little transmission, but this may not be realistic in the long—term. let's get some of the day's other news. chinese officials have confirmed that all 132 passengers and crew were killed when a boeing 737 crashed on monday. it was en—route from kunming to guangzhou when it broke apart and crashed into a mountain forest. the flight data recorders from the china eastern airlines plane have now been recovered. a european diplomat chairing talks to revive the 2015 nuclear deal with iran is to arrive in tehran as optimism grows that an agreement may be within sight. the eu's foreign policy chief said on saturday a new accord could be achieved "within days". discussions in tehran will

focus on closing the remaining gaps between the parties. protests have taken place at several british ports over the sacking of 800 workers at p&0 ferries who were replaced by lower—paid workers. members of the maritime union want customers to boycott the ferry company amid claims that inexperienced crews are operating the ferries and are a danger to shipping. colombian investigators say foo fighters drummer taylor hawkins had taken numerous drugs before his death on friday. a toxicology report showed traces of ten substances in his body, including cannabis, anti—depressants and opioids. fans of the us band, who were in bogota to see them play at a festival, have laid flowers outside the hotel where hawkins died. here's mark savage, and a warning that his report contains flashing images. # foo fighters — times like these. muscular but melodic,

taylor hawkins was the pulse of foo fighters�* music. # the best, the best, the best of you... # when hejoined foo fighters in 1997, he was their third drummer. but his connection with dave grohl was instantaneous. he's an amazing drummer. we have a mutual respect for each other. it's awesome, you know. born in texas but raised in california, hawkins fell in love with the drums the first time he sat behind a kit in his neighbour's garage at the age of ten. i took to it immediately. that day, there was a lightning bolt shot into me, and it was like... i was like, i'm a drummer, that's what i'm going to do. he came to prominence playing with alanis morissette, before

volunteering his services to foo fighters. he would often interrupt concerts to perform covers of his favourite band queen. foo fighters had been due to play a festival in colombia at the time of his death. 0rganisers lay candles on the stage and foo fighters posted a short statement online saying his musical spirit and infectious laughter will live on with all of us for ever. without that energetic and charismatic playing, the band will never be the same. taylor hawkins, who's died at the age, of 50. the duke and duchess of cambridge have been reflecting on their time in the caribbean, after a week—long tour marked by calls for independence

from the queen. prince william said he had "thoroughly enjoyed" spending time in belize, jamaica and the bahamas, but he acknowledged that questions about the future governance of the islands were for "the people to decide upon." here's our royal correspondent, jonny dymond. 0n the final day of the tour, a chance to see the damage wrought by hurricane dorian, two and a half years ago. the couple toured a church that was badly damaged in a community still pulling itself together. we dedicate this plaque and this wall to their memory. it was a chance to remember those who lost their lives. a moment of solemnity. the couple's time here was warmly appreciated. just down the road... ..a change of gear, change of mood. a traditionalfish fry and a culinary adventure for the duchess.

applause. then, into the crowd, enjoying the time away from the formalities of the tour. prince william says this tour has brought into sharper focus questions about the past and the future. he says he has learnt a lot and he says he is committed to serving and supporting the people of this region in whatever way they think is best. the strong suggestion as he leaves is that he is fine with the countries he has been visiting ending their link with the crown. jonny dymond, bbc news, the bahamas. you can reach me on twitter —

i'm @richpreston. thanks for watching. hello there. for most of us, saturday brought much in the way of sunshine. top temperature of 20.5 celsius was recorded in north—west wales in porthmadog. i want you to concentrate, though, on the skies in the east of england, where we had lots of sunshine and temperatures quite widely17—19 degrees. big change on the way, though, for sunday afternoon. those temperatures are going to be a lot lower. now, the reason for that is we're going to see an area of cloud that at the moment is in the north sea and is set to swing inland as the winds change direction to more of an easterly around our area of high pressure. now, there really will be just two types of weather around on sunday. a cold start for many of us, a few patches of frost around. you're either in the sunshine,

which many of us will have, or this zone of thick low cloud, which could bring a few spots of morning drizzle, be a bit misty as well. perhaps tending to brighten up a little bit into the afternoon across parts of the south—east, but a slow process and there could be areas where the cloud lingers all day. lincolnshire, norfolk will be most prone, temperatures there could just get to around eight or nine, still in the best of the sunshine, it will be another warm day for most, with temperatures again reaching the high teens. there will be more of that dry weather, more sunshine to go around on monday as well, but, across the far north of scotland, in shetland, we are going to start to see the winds turn to a more northerly direction and some colder air will be edging in here. still, for most parts of the uk, we are looking at fine, blue skies and much more sunshine. still mild for the time of year, but into the middle part of the week, we get these much colder northerly winds diving their way southwards, they are going to absolutely hammer the temperatures. that changeover really starting to take place on tuesday, there will be quite a bit of cloud around, a number

of showers and that colder air starting to make further inroads across the north of scotland. just six or seven for aberdeen and stornoway, still quite warm with temperatures into the high teens across parts of wales and south—west england. now, for wednesday, there will be some further showers around, temperatures continue to drop away and some of the showers turn wintry over the higher ground and then, look at this, wednesday night, into thursday, into friday morning, which is april fools�* day, could see a spell of hill snow across the pennines and wales and maybe down to lower levels. we will be keeping a close eye on developments over the next few days.

this is bbc news. the headlines: joe biden has accused russian president vladimir putin of being a �*butcher�* in his treatment of ukrainians, saying he �*cannot remain in power�*. the us president was speaking in poland where he met ukrainian refugees. the white house said mr biden had not meant he was supporting regime change in russia. the western ukrainian city of lviv has come under heavy rocket fire. the regional governor said five missile strikes hit a fuel depot and an industrial plant. lviv�*s mayor said no one was killed but five people were injured. and there have been tributes for taylor hawkins — the drummer with the rock band, the foo fighters — who�*s died at the age of 50.
