this is bbc news 7 i m lucy grey. our top stories... ukraine says it has retaken control from russian forces of the entire area around the capital kyiv — including this airport — panic must have ensued. look how this armoured vehicle has ended up ramming that one. they had no idea what the ukrainians had in store for them. relief as hundreds of people manage to escape the bombardment of the southern city of mariupol and reach safety. these people have been escaping any way they can, from cities, towns, villages that have been under russian bombardment. a two—month truce is agreed by warring parties in yemen for the first time since 2016, in a conflict which has killed an

estimated 400,000 people. marking a0 years since the start of the falklands war — when argentina invaded and occupied disputed islands they call the malvinas. and could tourism actually be part of the solution to the damage being done to antarctica's fragile ecosystem. ukraine says its forces have retaken the entire region around kyiv, with russian forces withdrawing from key towns. hostomel airport, which is near the capital and has seen fighting since the first day of the conflict is now back in ukrainian hands. but as russian troops retreat, the evidence of civilian killings — which is a war crime — is growing. reporters in the town of bucha which isjust outside kyiv, have found at least 20 bodies left in the streets. the bbc�*sjeremy bowen reports now from hostomel,

and a warning — his report contains distressing images. as the russian rearguard pull back from kyiv, ukrainian troops yet again were waiting. it looks as if they attacked out of the tree line. nimble ukrainian tactics and modern nato weapons are making tanks look obsolete. at least one charred body of a russian soldier was inside the wreckage of his vehicle. russian troops tried to do this, they were just defeated and ran away. so that is a sign that we can win the war. the road into bucha was littered with war debris. ukraine has saved its capital but russia is much better positioned in the east and south. winning for either side is a long way off. russia's defeat around kyiv may have started on this suburban

street in the last few days of februaryjust after the invasion. a long column of russian armour was destroyed as it pushed forward towards the capital. these were elite airborne troops, mostly in armoured vehicles light enough to be carried by aircraft. once again, anti—tank weapons and attack drones made them no protection at all. this is the graveyard, one of the many graveyards of russian hopes for capturing kyiv. it was early in the war, they were advancing. and then the ambush happened. panic must have ensued. look how this armoured vehicle has ended up ramming that one. they had no idea what the ukrainians had in store for them. young conscripts ran away — begging, local people said, not to be turned over to ukrainian territorial defence.

a neighbour said, "i felt sorry for them, they were so young, 18 to 20, with their whole lives ahead of them." it looks like the russians, as they prepared to pull out of bucha, had no such pity. at least 20 dead men, some with their wrists tied, were lying in the street as ukrainian troops entered the town. the mayor said they buried 280 people in mass graves. a few civilians who stayed said they'd tried to avoid the russians, cooking outdoors because their gas, power and water were cut. "this is the first bread we have had in 38 days," said maria. the russians systematically broke down doors to loot flats, they said. while they stole valuables

and food, the soldiers made them sit in the cellar. a few miles away the trail of devastation leads to hostomel airport, fought over since the first day of the invasion when russian airborne troops landed to use it as a base for a push into kyiv. the world's largest transport plane was destroyed early on. an enormous amount of national pride was wrapped up in this huge aircraft. it was a symbol of achievement, of ukraine's place in the modern world. now it is a symbol of what has happened to the country. the russians insist they never wanted to capture kyiv. the evidence is that they were stopped by more effective, determined ukrainian troops. leaving the battlefield around kyiv simplifies russia's new objective, a spring campaign in the east,

another attempt to break ukraine's will to fight. jeremy bowen, bbc news, hostomel. hundreds of people in the southern city of mariupol, which has endured weeks of bombardment by russia, have managed to escape in private cars. but a third consecutive attempt by the international red cross to drive buses to the city to evacuate people from the area has once again failed. many of those who've managed to leave are being taken to zaporizhzhia to the north west from where our defence correspondent jonathan beale sent this report this is what the aftermath of a russian invasion looks like — a trail of chaos, death and destruction. irpin, to the north of kyiv, is now back in ukrainian hands. but a bloodied and bruised russian army says it's now refocusing its military offensive to the east of the country. it's still meeting resistance there too. this, a russian helicopter shot

down over luhansk yesterday, believed to be the first time ukrainian forces have used the british made and supplied starstreak missile. yet russia's brutal bombardment in the east continues. these some of the survivors from its relentless siege of mariupol, which has been going on for weeks. translation: they've killed everyone and - destroyed everything. they are animals. there is nothing left there any more. no houses, nojobs, no people. her husband maxim says mariupol, the city he grew up in, no longer exists. "when i left i couldn't even recognise it. "the city is nowjust dust and smoke." these people have been escaping any way they can from cities, towns, villages that have been under russian bombardment and are now in russian occupied territory in ukraine.

and you can sense their relief when they arrive here. some of them genuinely look shell—shocked. thousands more are still trapped in mariupol. a red cross convoy of buses is still waiting to help. but many, like yelena's husband, are already dead. she still can't believe it. translation: bodies were everywhere, - literally everywhere. we tried to cover them, but no one collected them. there were dead kids, adults, everyone. what's your message to president putin? translation: stop war. stop war. the russians are tightening their grip on mariupol, at least what is left of it. for those fleeing the fighting, their city, their lives and loved ones are already gone. jonathan beale, bbc news, zaporizhzhia.

earlier, i spoke to elbridge colby a former pentagon official and asked him if the russia focus was shifting from kyiv to the east and the south. the russians are suggesting this was intentional but it's probably not true. that they are shifting their effort to go to the areas around the breakaway republics and the area along the black sea and that seems to be what is going on and of course we see these awful, horrible images of apparent atrocities, i think they are clearly atrocities. that is only going to catalyse the resolve of the ukrainians but it seems like the russians are not giving up so it seems more like there will be a shift in focus rather than a cessation at this point. in terms of military equipment, we keep seeing so many images of destroyed tanks and all sorts of military equipment on the russian side and i suppose people are more likely to share photos, ukrainians, of destroyed

military vehicles from the russian side but how is russia doing militarily, in terms of equipment? i think it's doing very poorly compared to what i think experts assessed and probably what the russians anticipated. i think what you're suggesting is there has been an enormous consumption, i don't want to use a overly technical term, use of munitions and aircraft and tanks and so forth. you mentioned the falklands war, that's one of the real lessons of modern warfare is how fast these things are used and a critical reason why it's important for us to support the ukrainians with additional lethal equipment because they are using it as well and it could make a difference as this moves hopefully towards a negotiated settlement, i think we can all hope for that but it will be determined by the battlefield more than anything else. will the equipment keep coming from nato? we have seen president zelensky addressing various parliaments and continuing to plead for more military equipment, will it keep coming?

i think there was a recent announcement that the united states would help broker the transfer of t72 former soviet tanks, warsaw pact tanks and other equipment, but i think there can be real significant material impact on the margins so it's very important and the united kingdom has been a leader, poland, but it's important for other members like germany and other nato members to continue to accelerate the transfer of conventional weapons to not only resist the russians but ideally push them back as much as possible. as you mentioned we are seeing accusations of atrocities, war crimes and president putin being accused of war crimes. do you think we will see that pursued? first of all we should recognise it as an abomination. i think, unfortunately,

president putin is protected by essentially the world's largest nuclear arsenal so we should bear in mind what we can and cannot do but i think the most important thing is to try to help the ukrainians as much as possible to expel the russians from as much of their territory as possible. that would be best for the ukrainian people. at the end of this conflict we may not be able to get the justice ukrainian people deserve but unfortunately that is the reality of international politics and when dealing with a great power, and it suggests the importance europe should take from this and especially countries like germany, of having a stout military deterrent and defence for nato and europe because you will not be able to get perfection in this war, at least. let s get some of the day s other news emmanuel macron has held his first rally of the french presidential election campaign — just over a week before the first round of voting. he told thousands of supporters in paris that he is fighting for �*social progress�* and to stop �*extremism' in french politics. polls suggest mr macron

is leading the race ahead of far—right rival marine le pen. reports from sri lanka say access to main social media sites has been blocked in the latest move by the authorities to prevent protests against worsening shortages of food, fuel and medicines. police have already declared a 36—hour curfew across the country and imposed a national emergency. at least eight people have been killed in coastal areas of brazil after torrential rains triggered flash floods and landslides. officials said the victims included a mother and six of her children. they died when a landslide swept away their home in the town of paraty, in rio dejaneiro state. the local mayor said at least 70 families were being housed in shelters and hostels. you are watching bbc news, the headlines: ukraine says it has retaken control from russian forces of the entire area around the capital kyiv — including the airport of hostomel.

relief as hundreds of people manage to escape the bombardment of the southern city of mariupol and reach safety. a two—month truce has been agreed between warring parties in yemen. it's the first nationwide truce since 2016 in a war which has killed nearly 400,000 people, according to un estimates. the deal between the saudi—led coalition and iran—backed houthi rebels came into effect on saturday — coinciding with the first day of the muslim holy month of ramadan. celestina 0luloday reports. the scars of a war that has raged for almost eight years and with it a humanitarian crisis, the most vulnerable struggle to survive. the united states says the two—month truth is a crucial moment. if the international community and the parties can work together, this can be built into a ceasefire, lasting ceasefire, and an inclusive political process that ultimately gives shape to a new yemen that i think

we are all so keen to see. the deal means stopping offensive military operations like this. gunfire. it is an agreement between the saudi—led coalition and the iran backed houthi rebels. a deal which also means fuel ships and commercial flights will operate from rebel held areas like the capital. but on the city streets, there is caution. translation: yesterday we saw on social media i and the media in general, a two—month truce, but it is not visible on the ground, but only in papers. crossings are not opened, nor has the currency been unified, nor have prices been lowered. the economic situation is generally deteriorating. translation: the truce is wonderful for us - and the region in general, a great thing.

and we hope that the truce will last, not only for two months, but rather permanently, because the people are tired and have suffered a lot. the first nationwide ceasefire since 2016, this fragile peace can be extended if both sides agree. a stipulation many hope will alter the devastating reality of a conflict that has led to countless deaths. how significant a development could this truce be? that's a question i put to gerald m feierstein, former us ambassador to yemen i think, as has been said, potentially it is very significant. it is the first time parties have agreed to any kind of a ceasefire. efforts in the past two agree to a

ceasefire for celebrations like ramadan, we will see if it holds this time, as your reporter said. holds this time, as your reportersaid. if holds this time, as your reporter said. if we can extend it, then this might be the beginning of a political process to end this conflict. white now, do you think? there is some speculation that her face are using this as a chance to regroup and others suggesting there was a stalemate that had come into being. why do you think it is happening now?— being. why do you think it is happening now? certainly what we saw over — happening now? certainly what we saw over the _ happening now? certainly what we saw over the last _ happening now? certainly what we saw over the last year - happening now? certainly what we saw over the last year was l we saw over the last year was the who think rebels making a real drive, military operations to try to seize the strategic critically important both economically and from a territorial standpoint. and for a long time, it looked like they were going to be able to succeed in doing that but we have seen more recently is that

the government aligned forces have successfully pushed that back and so it could be that the who think rebels have decided they needed a breather to regroup and they may also have come to the conclusion which is a critical issue, they may have come to the conclusion that they are not going to succeed militarily and therefore they should turn to a political process. the therefore they should turn to a political process.— political process. the big issue is _ political process. the big issue is this _ political process. the big issue is this major - issue is this major humanitarian crisis in the country, something like 80% of people in need of aid and we werejust people in need of aid and we were just hearing the figures, 400,000 people, the un estimates, have been killed since the fighting began. there is a little bit of hope in this, that more aid may be able to get in, even if this isjust a short pause, at least more aid will be able to get in?

absolutely. 0f aid will be able to get in? absolutely. of the 380 or 400,000 people who have died, it is important to note that most of them have died from disease or malnutrition not from the fighting itself. and so the humanitarian issue is critical, the coalition has agreed to allow fuel shipments to come straight into the port which is potentially important and it will also facilitate movement of humanitarian goods into the north where 70% of the population lives so again, very important. we're getting reports that many people have been injured in a huge explosion at a nightclub in the azerbaijan capital, baku. emergency services personnel are treating clubbers at the scene, amidst debris and damaged cars. it's thought a propane gas cylinder exploded.

argentinian forces landed on the falkland islands 40 years ago after a long running dispute about sovereignty. it sparked an unexpected war with britain which lasted 74 days. like many families there, the davidsons woke to the reality of life in a warzone. they've now made their home in the scottish highlands but as elizabeth quigley reports, their memories of a conflict 8,000 miles away, are still vivid. here in the peace of the highlands, war seems a distant memory. but for margaret and don davidson, the events of 40 years ago have never left them. we thought it was all posturing. we never thought for one minute that it would... it would happen. it was simmering away, but you never expected invasion. but that's exactly what happened. newsreader: argentina has invaded the falklands. - in 1982, the davidsons were running the malvina house hotel in port stanley and bringing up

a young family. all three of their children were born in the falklands. the youngest was just six months old when war broke out. explosions, rifle fire. that's how you know they're coming. we knew exactly what we had to do. we had to get the hell out of it... out of the way of it, and we went down to the cellar. you will find that in any warfare, you'll have seen it in ukraine. so how did they cope with being under argentinean rule? most of them had no idea where they were. they'd just been draughted in. they had no idea it was so cold. that we didn't speak spanish. in fact, they had no idea. i think a lot of the conscripts that had arrived and that expected to be welcomed with open arms. and today's events in ukraine bring memories flooding back of how they coped in a warzone 40 years ago.

i remember very, very vividly, it was the day after the invasion, i was... i was taking a shower and, um, ijust realised it was gone. your freedom. and that's why ukraine... ..deeply upsets me because you lose... you lose the freedom of speech, you lose the freedom of worship. you lose the freedom from want and you lose the freedom from fear. all gone. margaret davidson ending that report by elizabeth quigley in antarctica, scientists are concerned about the growing number of tourist cruise ships that could be damaging its fragile ecosystem. but many of the newer ships are more sustainable and even help to gather scientific data. so rather than being a problem, could tourism be part of the solution? julie ritson reports. trip of a lifetime is how many describe going to antarctica.

this incredibly alluring but remote location attracts around 60,000 visitors each year. these tourists are travelling on an expedition cruise ship that uses battery hybrid powered engines, has an impressive science centre, and equipment below deck that automatically analyses the surrounding sea water. this scientist visiting the ship for the first time wonders if it's capable of doing even more. this ship may be effectively used for real science, not only for education, not only the spread of information between the tourists but the tourists can help with the science. this professor has a five year research grant from the us national science foundation to study snow algae and how it affects the rate that snow melts, but she can't spend five years straight in antarctica so joining a trip like this works well for her.

i am able to collect some samples and data for my research and i can use some of the facilities on the ship, such as the microscopes, to look at the samples and also work with the tourists to show them what i am sampling in the snow. most of the ship's expedition crew also have science backgrounds and help run citizen science projects for the passengers. ..a little bubble of water on top and no air. studying the microscopic phytoplankton in the water helps monitor the effects of global warning. samples are packed up and sent off to be analysed by researchers who can't get here themselves. coming to places like antarctica costs a lot and takes a lot of planning so by integrating citizens into their science, they are able to collect data repeatedly at the same locations throughout the season while the tourist ships are already here. scientists also live and work in antarctica for many months of the year. this presents its own unique challenges, logistics

being one of them. this research base on livingstone island is temporary home to around 40 scientists, but their supply ship has been delayed and they're running low on food. luckily, our ship was nearby and able to help. for them, it has been a life—saver that tourist ships cruise these waters. but what the scientific community really hope is that the passengers return home as ambassadors who can educate others and help change behaviours that threaten this fragile environment. pope francis is on a two—day trip to malta and has visited the island of gozo. as he left the maltese capital, valetta, ceremonial cannon were fired from the city walls and crowds gathered at the quayside to wave him off. hundreds lined the streets for the pope's arrival in gozo and the pontiff followed an age old tradition by offering the golden rose to the ta' pinu national shrine, which is a holy sanctuary dedicated to the virgin mary.

you can reach me on twitter — i'm @ lucy e grey hello, there. another cold day on saturday but not as bitter as it has been because the wind was not as strong. we started with blue skies and a frost but as the day went by we had clouds building to bring scattered showers and even some hailstorms. for quite a few of you the weather is going to follow a similar pattern on sunday. right now we have clear skies for the majority. temperatures already below freezing. in the first part of sunday morning, a widespread and sharp frost, temperatures down to —3 in some towns and cities. there could be one or two icy stretches around first thing. for many of you, a lovely start to the day if somewhat cold. blue skies and plenty of sunshine. through the day, cloud bubbling up in england and wales and we may see some showers, the odd one with hail. in the north—west, outbreaks

of rain moving into northern ireland and scotland. heaviest rain in the highlands. temperatures similar to saturday, about 10 degrees. sunday night, the rain pushing south and east across the uk, introducing for many parts of the country milder atlantic air. the heaviest rain in western parts of the uk although some in the east which won't amount to much. a lot of cloud and perhaps some hill fog. also a lot milder than it has been, top temperatures around 14 or 15. in shetland, still cold. tuesday, we have some colder air moving down into the north of the country. for many of us, we are in this milder air with a lot of cloud and outbreaks of rain. something of a battle zone building in. with cloud and rain, some mist and hill fog. for most parts on tuesday it looks like it will be a mild

day with temperatures of around 12—15 across england, wales and northern ireland. in the far north of scotland, colder, down into the single figures. in the latter part of tuesday afternoon, the rain bumps into the colder air and looks like we'll see some hill snow in scotland, probably north of the central belt.

this is bbc news. the headlines: ukraine says its forces have retaken the entire region around the capital kyiv, with russian forces withdrawing from key towns. but, as russian troops retreat, the evidence of civilian killings is growing, with reporters in the nearby town of bucha finding at least 20 bodies in the streets. hundreds of people have managed to escape the bombardment of the southern city of mariupol and reach safety in private cars. but, a third attempt by the international red cross to drive buses to the city to evacuate people from the area has once again failed. a two—month truce has been agreed in yemen for the first time since 2016, in a war which has killed an estimated 400 thousand people. the deal between the saudi—led
