this is bbc news. welcome if you're watching here in the uk or around the globe. i'm nancy kacungira. our top stories — the russian invasion of ukraine continues. after shelling in the city of mykolaiv, a ukrainian soldier is pulled out of rubble alive after being trapped for 30 hours. very tense here. it looks like somebody heard planes overhead. i heard some explosions, and the soldiers told us to leave very quickly, which is what we're doing now. 80% of buildings in the port city mariupol have been damaged by the russian assault. those who've managed to get out have been describing what they've fled. translation: there is no mariupol. we sat in a cellar for ten days and did not leave once. we neither had water or electricity.

two former british prime ministers join calls for a new nuremberg—style tribunal to investigate vladimir putin for his actions in ukraine. welcome to bbc news. the united nations human rights office says that at least 847 civilians have been killed in ukraine since russian troops invaded more than three weeks ago, although the true figure is likely to be much higher. ukraine's president has called for comprehensive peace talks with russia "without delay". in the south—west, in the city of mykolaiv, a search—and—rescue operation is under way after a nearby ukrainian military base was hit by missiles. the city is a key russian target that has been blocking russia's

advance west along the black sea coast for weeks. our correspondent andrew harding has sent this report from there. hunting for survivors in the ruins of a ukrainian army base. it's believed 200 soldiers were in these buildings when russian missiles struck. ukrainian officials aren't saying how many died here, but it could well be over 100. suddenly a survivor is found. alive after 30 hours under the rubble in freezing temperatures. his name unknown for now, but most likely a local recruit fighting for a city that's taking a hammering. abruptly we're told to move fast. ukraine is full of these sudden scares. very tense here.

it looks like somebody heard planes overhead. i heard some explosions. and the soldiers told us to leave very quickly, which is what we're doing now. a few minutes later, the all—clear. but nerves are wearing thin here in mykolaiv, the front line for russia's black sea offensive. two shopkeepers emerge from a basement near the army barracks. translation: i can't tell you how scared we are. l we all live in the cellar now. when the bombs hit the army base, everything shook. and everyone's phones are filling up with pictures of their city's agonies. along the coast, a glimpse of how much worse things could still get. this is mariupol, or what's left of it. besieged by russia, hundreds of thousands of people are still trapped in the city. heavy fighting means no way out for them and no way to bring in food or water.

in mykolaiv, another air raid siren and the hard—earned knowledge that no—one's safe from russia's bombs. as we've seen today, the russians are sometimes targeting purely military sites, but more often than not it's civilian neighbourhoods like this one that are getting hit. nine people who were queueing on the street outside these shops were killed a few days ago by a russian bombardment. just two blocks away, this lorry driver is trying to clear up after this. by chance, he and his family were away when the bomb hit. "this isn't a war between armies," he says. "the russians are trying to destroy us all." back at the army base, heavy going as a front—line city waits

for news of any more survivors. andrew harding, bbc news, in mykolaiv, southern ukraine. our chief international correspondent lyse doucet is in kyiv and sent us this update a short while ago. the focus of russian forces seems very much to be on the southern coastal belt along the black sea and the sea of azoz. that is a strategic land corridor that it would like to seize. that's our understanding. that's what we see on the ground, a swathe of land which can connect connect eastern ukraine and the crimean peninsula, two areas of ukraine that it has held sway over since 2014. the situation here in kyiv, the capital, although it's long been

believed that this is also in moscow's sights, hasn't changed very much in the past few days. the air raid sirens continue to sound throughout the day. there are explosions, mostly on the edge of the city. many of them coming from the north—west. we also see dark plumes of smoke rising from the north—west where we know there has been quite intense fighting as the ukrainian armed forces try to push back russian convoys, back russian convoys, armoured convoys, right on the edge of this city. we also can see and hear in the skies the launching of ground—to—air missiles, evidence that the air defences of the ukrainian army are still intact, still holding and still a key part of the ukrainian defence. people in the ukrainian capital, kyiv, have been spending their nights underground to avoid the threat that hangs over their city. 0ur international correspondent 0rla guerinjoined them in a shelter built in soviet times.

the nightly routine as the curfew descends. they seek refuge below ground in kyiv. we can't say exactly where. some are glued to the radio, like a scene from wars gone by. and they bed down in darkness. forced into the shadows. our guide is zoe, a teacher and translator driven from her own bed by russian attacks. they bombed the city close to my apartment. at five o'clock in the morning, i got up like crazy, i didn't know what to do because it was frightening. you know, the building was shaking like this, so... and after that, i decided to come here. i'm sorry. before, i watched it only in the movies.

of the second world war started. 0nly movies about it, but now we are in this reality, you know? in a makeshift bedroom nearby, another echo of the past — a discarded lenin. many here believe vladimir putin is trying to drag ukraine and europe back to the dark days of the soviet era. at the dinner table, the discussion among friends and neighbours is about the defences around the city. and there are other worries here, like what to tell the children. julia says her six—year—old keeps asking questions. "we tell her she has to cope for a little while, and we hug her and kiss her," she says. then it's bedtime.

mother and daughter counting sheep. a familiar ritual in a time of danger and uncertainty. 0rla guerin, bbc news, kyiv. the ukraine military have announced a 38—hour curfew in the southern city of zaporizhzhia following a russian rocket attack. 0ur correspondent wyre davies is there. this is the town of zaporizhzhia. it's about 130 miles just to the north—west of the besieged city of mariupol, which, of course, has been virtually flattened by russian artillery fire. now, in recent days and weeks, those people who've been able to flee from mariupol have been coming through here. many of them, including children,

being treated at local hospitals. but the big fear here now is that this city will become the next target for the russian offensive. indeed, in recent weeks, there have been sporadic missile attacks in the area. and in the last 2a hours, seven people were reported to have been killed in attacks against a local training base and factories. and that's meant a curfew has now been declared, a 38—hour curfew, in this city declared by the army and by local authorities, and that's already led to pretty big queues at checkpoints in the city. people fleeing the city much north to the town of dnipro. of course, the fear is that even though many of these big old civic buildings are standing, that this city will soon resemble what has happened in mariupol. so far, it's been reported that around 6600 people were evacuated from ukrainian cities through humanitarian corridors on saturday.

ukrainian officials say it was considerably less compared to friday's attempts, with more than 9000 evacuees having managed to leave the warzone. in an online post, the deputy head of the president's office recorded 4128 people who had left the besieged port city of mariupol. zhanna bezpiatchuk is from the bbc ukrainian service. she sent us this update from the train station in lviv a little earlier as people made the journey from the west of ukraine to neighbouring poland. this is one of numerous vacation trains which is about to depart. it leaves for poland, for the polish town of chelm, just very, very soon, in a few minutes. there is no precise schedule for such trains, but it's about to depart. and believe me, almost everybody on this train doesn't believe that it might be a one—way journey for them.

people really believe that they will return to their homeland as soon as possible. i know that the family of one of my friends, one of my closest friends, is about also to take one of these vacation trains to the polish town of chelm within the next days. her mother, her brother and grandmother. then they will go to poland, from poland to france in order to reunite with the family there. so, that's the reality for many, many ukrainians, for hundreds of thousands of refugees from this country that have to flee it and flee the war of not their making. i talked also to many other people who stay here in western ukraine. i have to remind that yesterday the aircraft repair plant in lviv was hit by russian missiles, and many people that fled the war

in the other parts of the country and found the safety here in this part of ukraine. now they're really worried by this situation, but for many, the western edge of the country is the only safe place that they can hope for. because, for example, many mothers whose sons serve in the army, they are going to conscript or they'lljust continue their civilian work, important civilian work in this country. they want to stay in ukraine, support their children, support their granchildren, support their families. it doesn't mean really that everybody even from the areas which are heavily hit by the battles, by bombardments, want to flee the country. and this is still the safety, the safe place for ukrainians. the war has forced millions of ukrainians to leave their homes, and for those who have stayed put, finding food and medicine

is dangerous and difficult. earlier today, my colleague james reynolds was at a distribution centre just outside lviv where volunteers are gathering aid for people in need. in normal times, this- was a furniture warehouse, but since the start of the war, this has become an aid - distribution centre. it receives and then sorts. through tonnes and tonnes of supplies which have been sent from across the world. _ so, let's split up, you go this way and i'll go that wayjust to get - a sense of the scale - of what's been donated. and you're now walking through this column where people are sorting. out clothes and shoes. and on my side, people are sorting through tins and tins of food. - there are lots of volunteers here. some of them have been older, retired people. .

and they've decided to sign up l for six to eight—hour shifts here. they get bus rides in, _ and they sort through everything to make sure everything's in good order. _ and then the businesspeople who run this centre organise it. _ they'll start to re—pack it, i and they then are in contact with places across the country. which really need food and shoes and tins and tins of food. and one of the most important needs of all is medicine. - and if you just look over there, you'll see the pallets that - need to be sorted out. those have to be sorted out by specialists, - by doctors and pharmacists, i and they will then be sent out and driven out to the hospitals that need them most. - a ukrainian military spokesman has confirmed that a weapons depot in the west of the country was hit in a russian missile strike, but could not confirm whether moscow had used hypersonic weapons. russia's ministry of defence earlier said it had used hypersonic missiles to destroy the underground weapons storage unit in the

ivano—frankivsk region. it's the first time they've admitted using these types of missiles in combat. james bosbotinis is an independent specialist in defence and international affairs. he told us more about these types of missiles. yes, the kinzhal is an air—launched ballistic missile. it can travel at speeds up to ten times the speed of sound and has a range of about 2000 kilometres. it's designed to provide a precision strike capability against both targets on land and at sea. it entered service in late 2017, and, as noted, this is its combat debut. the speed of a kinzhal puts it beyond the reach of any ukrainian air defence system. and the launch platforms, in this case, the migs1—ik, can launch from ranges beyond the reach of ukraine.

the kinzhal was likely launched from southern russia. so, unfortunately for ukraine, there's no chance of defending against these hypersonic weapons. two former british prime ministers, gordon brown and sirjohn major, have called for a new international tribunal to be set up to investigate vladimir putin for his actions in ukraine. they've signed a petition alongside 140 academics, lawyers and politicians campaigning for a legal system modelled on the nuremberg trials of nazi war ciminals after the second world war. gordon brown spoke to bbc radio 4 earlier. go back to 1942, when the allies got together and said that they would punish war crimes, and that led to the nuremberg trials. what's unique about this is that we're seeing, as you just reported from mariupol, the indiscriminate bombing of civilians, which is against international law, the targeting of schools, hospitals and public buildings, against international law. we're seeing the breach

of humanitarian ceasefires. of humanitarian corridors that are being created by the russians, and of course we're seeing nuclear blackmail. all of these things are adding up to massive loss of life, of course. the petition was started by phillipe sands. he's a specialist in international law. he explained how the system could work. the idea that is now- beginning to slowly come together is the creation _ of a tribunal established by a small number of countries drawing i on the criminal law of ukraine and russia, which criminalises the crime of aggression - and internationalises the process. it might be situated in the hague. it would have an international investigator, an international| prosecutor, it would maybe have internationaljudges _ as well as ukrainian judges. this follows precedents that already exist in international law. _

and the first thing it - would do is gather evidence and it would identify persons of interest. | it's not complicated, - unlike war crimes and crimes against humanity which take years |to put together because you have| to link the act that is a crime with the perpetrator- and that is pretty tough for crimes against humanity and war crimes. | the crime of aggression's pretty straightforward. i so, the second thing that. would happen is you'd create list of persons of interest, - and that, ithink, would begin to galvanise people's attention. we'll return to ukraine in a moment, but first let's get some of the day's other news. china has reported its first covid deaths since january last year as it faces its worst outbreak since the early days of the pandemic. two people have died in the province ofjilin in the north—east. officials said they were elderly with underlying health conditions. china has continued with its zero—covid policy, locking down entire cities and enforcing mass testing. the family of a joint british

and iranian citizen held in iran say they feel betrayed by the british government. morad tahbaz, a 66—year—old wildlife conservationist, remained in iran while two other joint british—iranian citizens, nazanin zaghari—ratcliffe and anoosheh ashoori, were freed by tehran last week and allowed to return to the uk. here in the uk, p&0 ferries say some of their services from liverpool have resumed after all ships were called back to port on thursday. hours later, the firm announced 800 staff had been sacked and would be replaced with agency workers. the scottish government says it, too, is reviewing all publicly—funded contracts with the company. our business correspondent ramzan karmali reports. chanting: go, go, p&0! go, go, p&0! protesters let their feelings be known about the sudden dismissal of 800 p&0 staff outside the tory party conference in blackpool. the government really needs

to get its act together. rather than be leading the destruction of the british maritime industry, they should be doing all they can to reverse the loss of 800 jobs. in dover, the company's ferries lie idle. the dubai—based owners dp world have come under intense criticism on the way they have treated their workers. their families are going to be in need. it also means that local shopkeepers are not going to have the benefit of people spending. this is going to impact greatly on the wider community. the government now is also coming under scrutiny about the legal advice it took when told about the plans, and the scottish government's told the bbc it's reviewing all publicly—funded contracts with p&0. p&0 says it is now taking bookings for its crossing between liverpool and dublin. but for these ferries here in dover, and in fact eight across the whole country, the transport secretary grant shapps is insisting on full safety checks. this delay will undoubtedly

cost the company money, but it could also have an impact on businesses and passengers alike. one of europe's biggest transportation companies is worried. we are trying to move i all our trucks and trailers with cargoes to other lines, - but we understand every carrier now will do the same. so, we see the lines, - the queues slowly growing. absolute disgrace what's going on. the government has asked the insolvency service to check if dp world acted appropriately, but it's clear p&0's brand has been damaged by this week's firings. ramzan karmali, bbc news, dover. ballet stars from around the world are rehearsing for a gala performance in london this weekend. funds from the charity event will be donated to the disasters emergency committee, which is providing aid to people fleeing ukraine. tolu adayoye reports. uniting against war

including brazil, japan, argentina, france, the uk, as well as russia. we would like to show that russian doesn't equal aggression, russian doesn't equal what's happening now. it doesn't mean support for this war, and it should not be... ..thrown away or cancelled. you know, we... i love my russian friends. romanian ballet star alina cojocaru has co—directed. she trained alongside ivan in kyiv and will be performing at the gala. i hope i'm not going to get too emotional on saturday, but part of us... it's dancing out there on stage in hope. the message we want to send with this is that we are dancers, we're musicians, we're human beings and all we want to do is to be the little bit that we can. that i choose not to stand by thinking, "it's nothing i can

do about it, it's overwhelming, i have no power," to say, "there's something i can do, and i am doing it right now." let's not think we have no power. tolu adayoye with that report. russia's space agency has denied that three of its cosmonauts were showing support for ukraine by boarding the international space station wearing yellow uniforms. the cosmonauts docked safely on friday for a six—month mission joining american, german and russian crewmates already on board. the men's bright clothes, reminiscent of ukraine's flag, prompted speculation they were protesting against the invasion. but a statement from roscosmos said, "sometimes yellow is just yellow." it said the cosmonauts' flight suits matched the colours of the univeristy they attended. and just before we go, a reminder that you can keep across all the developments on the russia—ukraine war by going to our website. there we have a live page which is updated with latest reports from our correspondents on the ground. that's all on the bbc news website or download the bbc news app.

thanks for your company. stay with us here on bbc news. hello again. on saturday, we recorded the highest temperature of the year so far in scotland in the highlands in kinlochewe. we got to 20.2 degrees celsius. now, there were a few spots in europe that beat 20.2 degrees celsius. in portugal, for example, it was a couple of degrees warmer, but otherwise, actually, it was one of the warmer places in europe, comfortably beating all of these cities. athens just nine degrees through saturday afternoon. but it could've been worse. for anyone wanting a bit of warmth in turkey, actually saturday brought some snowfall, even into istanbul. now, our weather's been settled at the moment because we've got a big area of high pressure that's just to our east, and it's simply dominating the weather through sunday and for most of next week as well. clear skies at the moment. the wind slowly easing compared

with what we've seen over the last 24 hours or so. it'll still be there with some patches of frost and a few mist and fog patches through the vale of york and eastern areas of scotland. but otherwise, a lovely start to the day, lots of spring sunshine on the cards, probably a nice sunrise in northern ireland. here, though, we'll start to see a little bit working in from the west later on, and we'll see some cloud moving in across the east anglia threatening a few showers late in the afternoon. it is going to be a fine day for most of us, though, with some sunshine, but noticeably cooler. temperatures about 9—13, maybe a 15 locally in parts of scotland. and there'll be further showers running into eastern england, maybe even with a bit of soft hail into sunday evening. from there, though, the weather is going to get a lot, lot warmer. what will happen as we go through monday, this little curl of cloud, a very weak area of low pressure, could bring an odd shower into eastern scotland if it gets close enough. but otherwise, it's another mostly dry day with spells of sunshine. notice those temperatures rising across england and wales. 13 in cardiff, 15 in london.

still cool for scotland and northern ireland, but as these southerly winds continue to push northwards through tuesday and wednesday, those temperatures are going to surge significantly. so, tuesday, a fine day with some sunshine. maybe a few isolated showers developing through the afternoon. most of you will have a dry day, though. and look at these temperatures, reaching a high of 19 degrees in london, 15 in glasgow, 14 for belfast. and the fine weather with prolonged spells of spring sunshine for many of us will last for much of the week ahead, which temperatures on the warm side for the time of year.

sunak this is bbc news. the headlines... fierce street fighting has been hampering efforts to reach hundreds of people still trapped beneath a bombed theatre in the ukrainian port of mariupol. civilians who have been able to escape mariupol say conditions in the city are terrible. rescuers in the port of mykolayiv are searching for survivors among the rubble of a military barracks that was hit on friday in a russian missile attack. dozens of people are thought to have died. the un human rights office says that at least 847 civilians have been killed in ukraine since the russian invasion began. most of the casualties were caused by heavy artillery, missile and air strikes.
