this is bbc news — welcome if you're watching here in the uk or around the globe. lam ben i am ben boulos. here are our top stories. international condemnation of what appears to be the systematic killing of ukrainian civilians by retreating russian forces. explosions in the southern port of odesa — ukrainian officials say missiles have hit critical infrastructure. the city's mayor condemns the attack. windows blown out, roofs damaged in private houses. that was in the second straight. in the first the russians attacked peaceful houses. three homes were destroyed today.

pakistan's parliament is dissolved after prime minister imran khan survives a move to oust him — fresh elections could now be held within weeks. at least six people have been killed and ten are in hospital following a mass shooting in california's state capital, sacramento. the uk government rules out energy rationing as it prepares to unveil its plans on how to move away from russian gas and oil. hello and welcome to the programme. borisjohnson has condemned what he called russia's "despicable attacks" against ukrainian civilians in the country saying it is "yet more evidence that putin and his army are committing war crimes in ukraine." one of the areas is bucha — north west of kyiv — where there are reports of mass graves. it is here and in the surrounding towns that the bbc has filmed bodies

of civilians in the streets, some with their hands and feet bound — who had been shot. today calls for accountability have come from the us, the uk, germany and others — while russia has called the reports a fabrication. but the civilian suffering in ukraine is widespread. here's our correspondent, orla guerin. now the immediate danger has passed, the cost is being counted, home by home. some damage is irreparable. oleg takes me into his front garden — the scene of a possible war crime, where an ordinary family was hit by a russian missile. his two—year—old stan stefan was buried under the rubble.

translation: he fell asleep in bed | with new sheets because he wanted| to sleep in ones with stars, so my wife did that for him. he fell asleep, and he never woke up again. he says stefan knew the alphabet and could count to ten. he was lively and liked to play, but his final days were spent below ground hiding from bombs — not in the garden that was attended with love. the russians may have gone from around kyiv but oleg is sure the war will grind on. translation: while putin

is alive he will be trying - constantly to come to ukraine, and this war will continue unless there's a change in power in russia. and unless people learn what's really happening here. at front line is nearby, a glimpse of the damage, of the battles that raged here just a few days ago. ukrainian forces now reclaiming territory after the russians retreated towards belarus. well, here in this area the russians have withdrawn. ukrainian troops tell us that they were in a village just up the road. they occupied that village. they pulled back two or three days ago, and now ukrainian forces are inside the area checking for mines. in the village of kosorovychi, the russians fired from outside people's front doors, using them as human shields. that's according to mihailo, who had just emerged from the village,

and told me they killed one of his neighbours. "his house is at the end of the road," he said, "a two—storey house. he went home and opened the gate. he was found lying there shot dead." for the troops, a moment of rest. but there is new trauma here. every day new horrors are coming to light, and there are battles ahead, in the east and south of ukraine. orla guerin, bbc news, north of kyiv. as we've been reporting, there's been strong condemnation of the horrific scenes discovered in the commuter town of bucha, near kyiv, since russian forces retreated from the area. a warning — we are about to show you some distressing images of a mass grave in bucha. ukrainian officials say 57 bodies have been discovered, just outside the capital. nato leaders have voiced their shock and horror at new evidence of atrocities against civilians in ukraine, and have warned that russian troop movements away from kyiv do not signal a withdrawal or end to the violence.

the united nations said that the bodies found in bucha "raise serious questions about possible war crimes." stephen wilkinson is a specialist in international human rights in armed conflict. a short while ago i asked him how sure we can be that war crimes have been committed. these are potential international crimes, so like any crime even if we want to jump to that quick and clear conclusion we do actually have to let the investigations take place before we can make any authoritative determination. and just explain the sensitivity around it and the significance of saying that something is a war crime, because as i understand it it is very different to say it colloquially to the actual technical, legal definition? yeah, that's correct. so as lawyers we tend to be a little bit cautious. we've heard politicians who can of course speak in terms of war crimes, but as lawyers we speak about "alleged war crimes".

like with any domestic crime, we have to let the investigation process occur before we can make that clear determination. we would need a trial and a process. we need to identify notjust physical evidence but also the mental elements, so the intention of the actors involved. so war crimes are complex criminal investigations and that is why we tend to be a little bit cautious in making a clear legal determination. and by its nature, from what you have described, that is a lengthy and time—consuming process that history tells us it does not conclude until long after the events have ceased. in that sense, it feels like this notion of war crimes is aboutjustice after the event and holding to account rather than actually being able to prevent any continuation or further loss of life? well, i think that is the case but i would also hope that sometimes in some cases — not all — the threat or the kind

of starting of investigations can place pressure on actors to change their conduct. sadly, to date we haven't seen any evidence of that in the ukraine context, and of course we still would like to see the conflict come to an end, but if it does and when it does it is also so important we have accountability for the crimes that have been committed and we do see some justice. and i also acknowledge that in the short term that might not feel like enough but i think it still remains incredibly important. but how can finding of war crimes, if it comes to that, be enforced, if a country, for example, russia, may refuse to recognise the legitimacy of the court in question and refuse, say, to extradite? yeah, that's a huge challenge

for the justice field and the whole international criminal court investigation or even a national investigation that could be conducted in ukraine. we have also seen investigations start in sweden, and the big challenge will be getting offenders or suspects, getting them to kind of physically be present in those systems. so i'm not going to say that is not an issue, but i also don't think we can not continue with demanding justice, even if the chance of getting someone in court may be small in this moment. but we also know things change quickly and even if it might be difficult to see that now, a russian official before the international criminal court today, i certainly don't think we should feel it is never going to happen and i don't think that should stop us continuing with the investigation. stephen, thank you very much for explaining that also clearly, stephen wilkinson from the diakonia international humanitarian law centre, thank you. earlier i spoke to our correspondent emma vardy who is in lviv, western ukraine. as russian troops are withdrawing from certain areas it means

journalists and camera crews are able to get in, and particularly in the town of bucha where journalists have been brought there there are these terrible scenes emerging of some streets littered with the bodies of civilians who appear to have been shot dead, some with their hands and legs tied. now, ukrainian officials and prosecutors are claiming in the last hour they have found the bodies of more than 400 civilians in bucha. ukrainian officials claim this is evidence of russian troops leaving behind evidence of war crimes as they retreat. some ukrainian officials say they've had to bury more than 200 people in mass graves. of course this is early days. these are the picturesjust coming out merely in the last couple of days from journalists on the ground. there has been mounting condemnation across europe, the nato general secretary saying this represents brutality against civilians that hasn't been seen for decades in europe. now there has been a very strong statement from russia today rejecting these allegations of war crimes, saying the scenes have in some way been fabricated to show to western media.

of course that's a claim that russia has made before. what will have to take place now of course is to get experts on the ground. they'll be there to gather evidence of potential war crimes and establish exactly what has gone on in the days ahead. and given what we have just been talking about, emma, does this in any way change the position of the western nations, the nato alliance, of not getting directly involved militarily, or does that now have to be revisited in light of the horrific images we have been seeing? well, of course, nato's position has always been it doesn't want to escalate the conflict any further and widen the military aggression by getting involved but of course this has really sparked a huge reaction today and the scenes coming out of course are gathering a lot of attention, notjust across europe but in america as well. so naturally i think those questions will come to the fore again, about whether nato is doing enough, but the ukrainian government throughout this has been calling for more assistance,

calling for nato to do more. there was a bit of an unknown factor, really, wasn't there, while russian forces held certain bits of territory while being bombarded and surrounded? journalists of course weren't able to get in, and now that picture is becoming clearer and many wonder what the scene will be like in the besieged city of mariupol which is of course still surrounded by russian forces and there are still aid convoys waiting to get in and eyes will be on that city to see what is left behind when people do manage to reach the civilians trapped in there as well. emma vardy for us in lviv. let me bring you a line of breaking news. we are hearing some civilians have been killed and 23 wounded in shelling in the ukrainian city in the north—east, kharkiv, close to the north—east, kharkiv, close to the russian border. this update is

according to the regional governor there. some civilians, we don't know how many, but some have been killed and 23 wounded in shelling in the ukrainian city of kharkiv. let's turn our attention to some other news now. at least six people have died in an early—morning shooting in sacramento, california, the city's police department has confirmed. police said several blocks of a commercial stretch of the downtown area were closed while they investigate. they also say at least ten people have been injured in the shooting. our north america correspondent david willis gave us this update from los angeles. a total of six dead, ten injured, according to reports on the ground there from the state capital, california's state capital, sacramento. this is a downtown area, littered with bars and restaurants, close to an arena called the golden one center, where basketball games and concerts take place. indeed, there was one taking place there earlier this evening. and the police say that office is located at least 15 shooting victims,

including six who are deceased. officers located at least 15 shooting victims, including six who are deceased. as you heard in that interview a short while ago, the police have no suspects in custody and they're appealing for any witnesses to come forward, anybody who might have a video. there is some unverified video circulating on social media which shows a group of people, women and men, involved in a scuffle on the street corner, whereupon gun shots can be heard, and there are unconfirmed reports, ben, that somebody opened fire from a gun, firing at least 50 shots from an automatic rifle. as i say, those reports are currently unverified. and, david, just to reiterate, then, so as things stand, no—one has been arrested, whoever has done this is presumably still at large, and what are police are advising — presumably to stay away from the area? yes, and i think the timing given

for this incident is significant. about two o'clock in the morning, ben, a time when bars and restaurants here in california close, so obviously a lot of people outside those sort of establishments, milling around. but nonetheless this is a mass shooting — very unusual in this particular part of the world, in this way, and indeed the local mayor, darrell steinberg, has tweeted, "rising gun violence is the scourge of our city, state and nation. "i support all actions to reduce it." and of course president biden has made various attempts to increase the controls on the availability of firearms in this country. nonetheless, 23 million firearms were purchased in this country in the year 2020 alone, ben.

david willis there. the president of pakistan has dissolved the country's parliament on the advice of the prime minister imran khan, who's survived a move to oust him from power. the parliament's deputy speaker dismissed a no confidence motion against the government, saying it was unconstitutional. fresh elections are now expected to be held in the coming weeks. mosharraf zaidi is a political analyst and columnist and former policy advisor to the pakistan ministry of foreign affairs between 2011 and 2013. good to have you with us. give us the background, who was trying to oust imran khan from power and why? imran khan has been a sort of mediocre, _ imran khan has been a sort of mediocre, from a political strength perspective, prime minister, ever since _ perspective, prime minister, ever since he _ perspective, prime minister, ever since he took office in 2018 and took _ since he took office in 2018 and took the — since he took office in 2018 and took the oath. what has been required _ took the oath. what has been required throughout his political career— required throughout his political career but especially to get to this level of— career but especially to get to this level of prime minister and sustain that position is a quid pro quo with the pakistani military which he

for shedding some light on that for us. the polls in hungary havejust closed in a general election dominated by the war in neighbouring ukraine. the prime minister, viktor orban, who has been seen as close to president putin, is seeking a fourth term in office. he is facing an alliance of six opposition parties. turnout has been high. serbians are also voting today in presidential and parliamentary elections. president aleksandar vucic and his progressive party are looking to extend their decade—long hold on power. but opposition parties are contesting the elections — after boycotting the parliamentary vote two years ago. the transport secretary has said the uk will not be considering energy rationing — as some european countries are — because of the pressure on gas supplies due to the war. days after energy bills increased significantly for households in england, scotland and wales, a new energy strategy is due to be released — as the bbc�*s politcal correspondent iain watson reports. with fuel costs soaring, some people are already rationing their own energy use.

david is on universal credit and at his flat near sheffield he has stopped using gas. he now relies on relatively cheaper electricity for washing and heating. we are living in the 21st century and ifeel as if i am going backwards and doing things that, you know, are probably what you would hear people did in the olden days. the government has not ruled out more help for fuel bills in the coming months, but labour and some conservative mps have been turning the heat up on the government now. i feel angry at the scale of the crisis people in this country are facing and the lack of response from government in the spring statement and promises of things, announcements in the future, just won't cut it. but this week, the prime minister will focus on what the government will do in the longer term to secure the country's energy supplies

in a more volatile world. it was almost a month ago when the prime minister promised us a new energy strategy within days, but the details and the financing have proved tricky. some of his own cabinet colleagues were worried that any moves to make it easier to build new, onshore wind farms in england, could prove politically unpopular, so i am told any specific targets for increasing wind production onshore could be dropped. people could be given lower fuel bills if they agree to have wind farms in their area, but the core energy strategy will focus on new nuclear capacity over time and an expanding offshore wind. by and large, i think it is better to build significant wind power offshore. i think that is where it performs better, because it tends to be windier, apart from anything else, you can build it, huge masts, much, much bigger than they could ever be onshore. more controversial are plans to increase north sea oil and gas

production in the short—term. the government says its commitment to reduce carbon emissions is unshakeable, but a lot of political energy will now be needed to change how we power our industries and heat our homes. iain watson, bbc news. the biggest cooking oil bottler for uk shops has said it only has four weeks' supply of sunflower oil left and that after that it will be "tight". ukraine and russia produce most of the world's supply. sunflower oil is used in some ready meals, crisps, peanut butter, mayonnaise and biscuits. food manufacturers are now racing to find alternative ingredients, but costs are going up with demand. the bbc�*s business correspondent emma simpson reports. everyday food — products which all contain sunflower oil. it's now in short supply, and here's a man who knows all about it. so from the uk perspective, we use the biggest amount of sunflower. so out of all the oil types, so if you take rapeseed, olive oil, corn oil,

sunflower�*s the biggest oil that is used by the uk. wow. so how much supply of it do you have left? so from our perspective of brands, we've got around about four weeks at the minute. we're still trying to see if we can get some more, but it's looking very tight from a supply perspective after then. if you buy any sort of cooking oil from the supermarket aisles, chances are it's been bottled here. 80% of the global demand for sunflower oil comes out of russia and ukraine. so, obviously, with everything going on out there, we physically can't get sunflower to be coming out of the country. you need a lot of it to make crisps. this small producer has already switched to rapeseed oil to keep production going. there's an incredible scramble. everyone's doing the same thing. so while sunflower oil is impossible to get at the moment, rapeseed oil is possible but difficult to get, and obviously because everyone's having the same idea, the prices are skyrocketing at the moment of rapeseed oil. at least labelling rules have been relaxed for an industry with a lot on its plate.

so at the moment, the immediate focus is on sunflower oil and on other rapeseed oil and like products. but there will be many more products which will be affected as we go through the coming months, and they're going to have to be reformulating hundreds and thousands of products at real speed. back at the bottling plant, they're now working 21w, ramping up the flow of rapeseed and other oils to make sure shoppers have options. emma simpson, bbc news, erith. right, let mejust bring you an update on those reports of atrocities and mass graves in the town of bucha north—west of ukraine — antonio guterres the secretary general of the united nations has tweeted the following. "i am deeply shocked by the images of civilians killed in bucha,

ukraine. it is essential that an independent investigation leads to effective accountability. " we will bring you any updates right here on bbc news. thank you for watching. hello there. a big change is taking place in our weather. some places started on sunday morning with temperatures below minus seven celsius, but monday morning will start on a much milder note, but with some damp and breezy weather, courtesy of a frontal system pushing in from the north west. it is a warm front so, as the name suggests, behind it, the air will be turning warmer, or at least milder. this wedge of milder air spilling south eastwards across the uk dominating the weather as we head into monday. so, as we go through tonight, that frontal system will bring cloud and outbreaks of rain, moving south eastwards and particularly heavy rain over higher ground in western scotland and after a chilly evening in the south, temperatures will tend to climb through the night,

so by monday morning, 6—11 degrees. a very, very different feel, but with lots of cloud, some outbreaks of rain, some heavy bursts of rain, clearing southwards through the morning. and then in england and wales seeing something a little drier, still with a lot of cloud, the odd spot of drizzle, limited brightness, showery rain then returning to northern and western scotland and parts of northern ireland, as we go through the afternoon. top temperatures typically 11—15 degrees, so milder than it has been, but colder than that, though, across the far north in shetland. and as we move out of monday into tuesday, we bring this weather front southwards. this is a cold front, so it tries to reintroduce some cold air. now, at this stage it looks like the cold air will not make a lot of progress southwards, so most of us stay with mild conditions. some brightness down towards the south, generally quite a lot of cloud, outbreaks of rain especially through northern england, northern ireland and southern scotland and then on the northern edge of that weather system, well, remember that cold air? it is likely that we will see some snow, especially

over the high ground, in the highlands, and the grampians. we could be looking at 10 to maybe 20 centimetres of snow, particularly as we head into tuesday night. just four or 5 degrees here on tuesday afternoon, four in aberdeen, ten in glasgow and from glasgow, edinburgh southwards, we stay in the mild air. through tuesday night into wednesday, this area of low pressure moves its way eastwards, deepening as it goes, there will be some brisk winds, still some snow in northern scotland, lost three showers elsewhere on wednesday in that cold air tries to sink further south as we head towards the end of the week, there could be some further wintry weather for some.

this is bbc world news, the headlines... international condemnation of what appears to be the systematic killing of ukrainian civilians by retreating russian forces. explosions in the southern port of odesa —— ukrainian officials say missiles have hit critical infrastructure. pakistan's parliament is dissolved after prime minister imran khan survives a move to oust him — fresh elections could now be held within weeks. at least six people have been killed and ten are in hospital following a mass shooting in california's state capital, sacramento. now on bbc news it's time for sportsday.
