this is bbc news 7 welcome if you're watching here in the uk or around the globe. i m shaun ley. our top stories... hundreds of people escape the besieged ukrainian city of mariupol but the red cross�*s evacuation efforts have once again been frustrated. we can facilitate the passage, the safe passage for civilians, once both parties come to agreement. and, unfortunately, until now, this has not materialised. russian troops use what appear to be stun grenades to disperse a pro—ukraine rally by residents of the occupied town of enerhodar. the bbc makes it to an airport close to kyiv, now liberated from russian control. a symbol of modernity, of ukraine's place in the world. striking out across the globe.

and now, it's a symbol of what's happened to the country. elsewhere, emmanuel macron has held his first rally of his french election campaign. he told supporters he's fighting for social progress. hollywood actor will smith resigns from the oscars academy after slapping the comedian chris rock. hundreds of residents from the besieged ukrainian city of mariupol have managed to escape in private cars and have arrived at reception centres to the north. however a third attempt by the red cross to bring a fleet of dozens of buses to the city has once again been frustrated.

they are spending the night en route and will resume theirjourney in the morning. the plan was to bring in desperately needed food and medicines and help evacuate several thousand people. on friday, they were forced to turn back, having failed to obtain the right security guarantees from russian troops. meanwhile, the authorities in the occupied town of enerhodar say russian forces fired tear gas and �*flash bang' stun grenades at demonstrators during a pro—ukraine rally. residents had gathered in the town centre to voice their support for their country when they were violently dispersed. the authorities also said four people were wounded when russian forces bombed another part of the town. our correspondent anna foster is in lviv. anna, anna foster is in lviv. can we talk first of all about

what anna, can we talk first of all about what is happening in mariupol, or rather what is happening? that what is happening in mariupol, or rather what is happening?- rather what is happening? that is riuht. rather what is happening? that is right- again. _ rather what is happening? that is right- again. we _ rather what is happening? that is right. again, we have _ rather what is happening? that is right. again, we have another- rather what is happening? that is. right. again, we have another day, another attempt at establishing a humanitarian corridor, which has been frustrated. they first talked about doing this on thursday this week. they said at the beginning of the week it was too dangerous, that they had information, or the ukrainian government said there was information that russia might potentially fire on fleeing civilians but as the week went on, we came to thursday and the international committee of the red cross said they believed they might be a window of opportunity to try to bring people out of mariupol, but for the last three days, they have tried and failed to reach that city. at the moment, it you can see in ukraine it is dark, i can tell you it is bitterly cold, and people living in mariupol, we think 160,000 of them, they have had no little electricity for weeks, no food, very little water, very few medical supplies, so each day that this

convoy out is delayed as another day that people are living in these terrible conditions. what the icrc had said, and you had them a few memos ago, is that if they are going to do this, the conditions have to be exactly right. both sides have to agree to a ceasefire for a period of time, they need to agree on locations, they need to agree on duration. if you are going to bring out a convoy of people, potentially on buses or in private civilian cars, you need to make sure that nothing is going to go wrong. we know they have tried to establish the humanitarian corridors more than once and they have failed. they don't want a disaster on their hands. but again for the third day, we are told those efforts have been frustrated. the we are told those efforts have been frustrated. ~ ., ., frustrated. the ukrainian authorities _ frustrated. the ukrainian authorities talking - frustrated. the ukrainian authorities talking up - frustrated. the ukrainian. authorities talking up their achievements in repulsing the attacks around kyiv and taking back more and more territory. in bucha, there are pretty grim signs of the retreat by russians. the?

there are pretty grim signs of the retreat by russians.— retreat by russians. they are a-rahic retreat by russians. they are graphic and _ retreat by russians. they are graphic and horrific _ retreat by russians. they are graphic and horrific pictures | retreat by russians. they are i graphic and horrific pictures and videos that have come from bucha. 0ne videos that have come from bucha. one very small area of the town, one straight almost it looks like, 20 civilian bodies on the ground, some of them with their highest hand —— their hands tied behind their back, people align where they have fallen. in one image, there was a man on a bike and he literally lives with his hand still on the handlebars, it looks like the boys have the mayor for several days. looks like the boys have the mayor forseveral days. —— looks like the boys have the mayor for several days. —— the bodies have been there for several days. the un human rights chief spoke a few days ago about evidence of russia firing on residential areas, homes and hospitals, she said that would be looked at for evidence of potential war crimes. but again what we see today, and we may see, we don't know for sure, today, and we may see, we don't know forsure, but today, and we may see, we don't know for sure, but we may see more of, as ukrainian forces move into those towns and settlements of kyiv, these

other kinds of scenes that it appears that russia leaving behind. anna, what about this protest in enerhoder? what do we know about was —— what was happening and what casualties they have been? we -- what was happening and what casualties they have been? we have seen these videos _ casualties they have been? we have seen these videos that _ casualties they have been? we have seen these videos that have - casualties they have been? we have l seen these videos that have emerged on social media, as often happens. this is a russian occupied town in ukraine, in southern ukraine, and it appears there was a pro—ukrainian rally that was held, that russian forces fired tear gas and flash bangs at these people as we were there. we were told that apparently four people were injured in a separate attack. but it shows you, and you see it in different degrees across this country, you see it here in a place like lviv where people continue their everyday lives, when a siren sounds, for example, it was a siren sounds, for example, it was a week ago on saturday when we had an air strike a week ago on saturday when we had an airstrike very a week ago on saturday when we had an air strike very close to where i am now, so the resistance in places

like this is people going about their everyday lives. the resistance and some of those russian occupied towns is people, if they feel brave enough to go out on the streets and have a demonstration like this one, but as you saw, russia, that is not the sort of thing they want to say, and it appears they took decisive action to stop that from happening. —— want to see. an adviser to president zelensky has said russian forces are making a rapid retreat, north of the capital kyiv. the uk ministry of defence said there was information they had withdrawn from hostomel airport, which has seen fighting since the first day of the conflict. the bbc�*sjeremy bowen has reached the airport. you have to watch where you put your feet here in the, well, the ruins of hostomel airport, about ten miles from the centre of kyiv, and on day one of the invasion, this was one of russia's main targets. a great big open area, they could land planes, helicopters, and use it as a staging area for their push into the capital. now of course that didn't happen, ukrainian resistance was too stuff,

and you can see there was a massive battle here. there is a huge amount of debris. all round the perimeter there is broken tanks and lots of unexploded ordnance of different kinds. and in the midst of it all, there is this. this is the wreck that was the maria, the dream. maria in ukrainian, and it's — was the world's biggest cargo aircraft. a huge amount of national pride was wrapped up in this as well, it was a symbol of modernity, of ukraine's place in the world, striking out across the globe. and now, it's a symbol of what's happened to the country. pope francis has called for a shared response to the world's growing

migration emergency. speaking to officials in malta after arriving for a two—day visit, the pope also appeared to criticise the russian president, vladimir putin, saying a "powerful leader" was stirring up conflicts for nationalist interests. emmanuel macron has been holding his first rally of the french election campaign — just over a week before the first round of voting. he told around 30,000 supporters in paris that he is fighting for social progress and to stop extremism in french politics. with just days before the first vote, polls suggest president macron is leading the race ahead of far—right rival marine le pen. he also promised employment for everyone. here he is speaking at that rally a short time ago. translation: working more also means more people working. yes, i am aiming for full employment. because thanks to everything we have done together over these five years, for the first time since

the mid—1970s, our country can say that it will reach full employment in the next five years. yes, it is possible. our correspondent explained what the president had been staying at the rally. well, it was an important moment for the president because, as you were saying, it was his only rally ahead of round one in a week's time and it comes at a time when a lot of people are saying his campaign has never really taken off so this was a chance for him to energise the faithful and send out the message that he is campaigning, that he is not completely taken up with the war in ukraine and talking to world leaders and so on. but that his number one priority now is focusing on the concerns of the french. there was a lot about his past mandate and the achievements and the way he

fulfilled them, commitments he had made in his first campaign five years ago and then more of the same for the future. a lot about social reforms he was promising and that is interesting because it suggests he was trying to send out a signal to the left or the centre—left people who he wants to very much come on his side if, it seems like the comic turns into a run—off with marine le pen. he is very aware that people on the left might be tempted to think a kind of curse on both your houses, both marine le pen and emmanuel macron. he wants to be clear to left—leaning voters that there is a very big difference between him and marine le pen and if it comes to a run—off with marine le pen, he wants them on his side. will smith has resigned from the academy of motion pictures — the organisation that hands out the oscars. the actor described slapping the comedian, chris rock,

at this year's ceremony as "shocking, painful "and inexcusable". the academy have accepted his resignation, but are continuing with disciplinary proceedings. our correspondent, duncan kennedy, reports. laughter. from beloved film favourite... oh, wow! ..to hollywood villain, will smith's slap of chris rock stunned the oscars. i want to apologise to the academy, i want to apologise to all my fellow nominees... his own award acceptance speech divided people, as he did not say sorry to rock. that only came later in a social media post, but now will smith has gone further. in a statement he said... will smith resigning, - i think the whole, you know, i think that was the best move

that he could take before - the academy decide, - before the academy decided to maybe expel him. given its status as the inner circle of the american film industry, losing his membership of the motion picture academy will hurt will smith. in its statement, the academy said... but what could that mean? questions remain about what is going to happen to his oscar. in the past, the academy has chosen not to remove oscars, even from disgraced figures like roman polanski and harvey weinstein. no, never! you all will never do that again! with a typical hollywood twist on events, one of his films due for release is a follow—up to bad boys.

the sequel to will smith's own life may depend on how the academy reacts when it meets later this month. duncan kennedy, bbc news. david warburton, the mp for somerton and frome, has had the tory whip withdrawn pending an investigation into allegations about his conduct. the claims about mr warburton, who sits on the backbenches, are being examined by parliament's independent complaints and grievance scheme. mr warburton has been mp for somerton and frome since 2015. a spokesperson for the whips office said the party whip had been removed while the investigation was ongoing. bookings have opened for five to 11—year—olds in england to receive a low—dose covid vaccine. experts recommend children receive two of the jabs; which contain just a third of the adult dose.

they will be available from hundreds of locations from monday. adam finn is a professor of paediatrics at bristol medical school and member of thejoint committee on vaccination and immunisation spoke to us earlier. it is very much for people who want to have their children immunised. clearly, children are at much lower risk from covid than old folks like me and the imperative to get immunised which exists for older people doesn't exist for children. but parents who want to have their children immunised and get some extra protection against a possible future wave of coronavirus are now welcome to come forward. these are vaccines that have common side—effects, as we all know. there is a reasonably strong possibility of headaches and fevers for a day or two, children might even miss a day of school as a consequence but those are short lived and not serious side effects. the more serious side effects that effect the heart are vanishingly rare, and so that is not something that parents should be too concerned about.

the duke and duchess of york have been named in a court case in which a turkish millionaire is claiming £38 million has been "dishonestly misappropriated" by a business adviser who denies the claim. the high court in london has heard claims that "substa ntial sums" from nebehat isbilen were paid to prince andrew and his ex—wife sarah. it is understood that three quarters of a million pounds has been repaid by prince andrew to mrs isbilen. drivers heading for cross—channel services at the port the port of dover says it's working hard to ease congestion, but its main approach roads are still "very busy". people waiting to board ferry services have reported having to wait up to nine hours. p&o ferries are suspended after they sacked most of their staff and the alternative company dfds are running a reduced number of crossings because one of its ships was damaged while docking in strong winds. earlier our correspondent, simon browning described how the disruption was affecting travellers.

there are substantial delays down at dover this morning. there is an accumulative amount of reasons why that has happened. you have mentioned one of the main ones, p&o, they took their ships out of service more than a fortnight ago and that has really hit capacity on the cross—channel shade dashed the cross—channel shade dashed the cross—channel strait between dover and calais. there are two ships out of service. with so much capacity out of the channel, queues are backing up. here in the uk, there has been an early start to sum for the easter holidays so we are starting to see passenger traffic return, people heading back down to the channel, people going to the beaches, but a lot of people want to get back to see family, earlier this morning i spoke to a man heading back to a small town outside cologne with his wife and two children to see his parents and parents are low, the kids haven't seen their grandparents for more than two years, and they arrived in dover and

they are stuck in a queue. i am years, and they arrived in dover and they are stuck in a queue.— they are stuck in a queue. i am in brookfield — they are stuck in a queue. i am in brookfield place _ they are stuck in a queue. i am in brookfield place in _ they are stuck in a queue. i am in brookfield place in dover, - they are stuck in a queue. i am in brookfield place in dover, we - they are stuck in a queue. i am in brookfield place in dover, we left london _ brookfield place in dover, we left london this morning at 5am to be the first to _ london this morning at 5am to be the first to change our p&0 to into another — first to change our p&0 to into another ticket. first to change our p&0 to into anotherticket. being first to change our p&0 to into another ticket. being stuck here for the last_ another ticket. being stuck here for the last two hours, you can see the queues, _ the last two hours, you can see the queues, this— the last two hours, you can see the queues, this is dover. i am here with_ queues, this is dover. ! am here with my— queues, this is dover. i am here with my family, we are going to germany— with my family, we are going to germany to see my parents for the first time _ germany to see my parents for the first time in— germany to see my parents for the first time in two years. i am an nhs nurse. _ first time in two years. i am an nhs nurse. i_ first time in two years. i am an nhs nurse. lam— first time in two years. i am an nhs nurse, i am working with immunisations in london, we thought this would _ immunisations in london, we thought this would be an early start to the easter— this would be an early start to the easter holidays. you can see it has come _ easter holidays. you can see it has come to— easter holidays. you can see it has come to a — easter holidays. you can see it has come to a standstill, it has been for awhile — come to a standstill, it has been forawhile. i come to a standstill, it has been for awhile. i told come to a standstill, it has been for awhile. itold my come to a standstill, it has been for awhile. i told my parents we are not going _ for awhile. i told my parents we are not going to — for awhile. i told my parents we are not going to be there before the evening — not going to be there before the evening. is probably true but i know dover— evening. is probably true but i know dover has _ evening. is probably true but i know dover has nice places and also has a

really dented travel confidence. here we are, easter two years later and people want to travel again but unfortunately during the pandemic so many of those travel businesses had to cut thousands of staff just to save themselves. as we are rushing back to apples and wanting to travel again, there are staff shortages. british airways said it is busy today in heathrow, a small number of panjust —— today in heathrow, a small number of pan just —— cancellations. manchester airport says it is seeing longer queues than normal. people queueing for up to four hours just to get through to security and we are very much only at the start of the easter break. a0 years ago today — argentinian forces landed on the falkland islands after a long running dispute about sovereignty. it sparked an unexpected war with britain which lasted 7a 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 a0 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. 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 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. they had no idea 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 a0 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. 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. this incredibly alluring but remote

location attracts 60,000 visitors each year. these tourists are travelling on an expedition cruise ship that has battery powered engines, and has equipment that automatically analyses the surrounding sea water. this scientist visiting the ship for the first time wonders if it is capable of doing even more. this first time wonders if it is capable of doing even more.— first time wonders if it is capable of doing even more. this ship may be effectively used _ of doing even more. this ship may be effectively used for _ of doing even more. this ship may be effectively used for real— of doing even more. this ship may be effectively used for real science, - 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 tourists but the tourists can help with the science.— tourists but the tourists can help with the science. this professor has a five ear with the science. this professor has a five year research _ with the science. this professor has a five year research grant _ with the science. this professor has a five year research grant from - with the science. this professor has a five year research grant from the | 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 spent five years strait in antarctica so joining a trip like this works well for her. i am able to collect some samples and data from my research and i can use of the facilities on the ship, such as

the facilities on the ship, such as the microscopes, to look at the samples and also work with the tourist to show them what i am sampling the snow. most of the ship is my expedition crew also has science backgrounds and help run citizen science projects for the passengers. aha, citizen science pro'ects for the passengers._ citizen science pro'ects for the assenuers. ~ , , , ., ., passengers. a little bubble of water on to and passengers. a little bubble of water on tap and no _ passengers. a little bubble of water on top and no air. _ passengers. a little bubble of water on top and no air. studying - passengers. a little bubble of water on top and no air. studying the - on top and no air. studying the microsmpic — on top and no air. studying the microscopic phytoplankton - on top and no air. studying the microscopic phytoplankton in l on top and no air. studying the l microscopic phytoplankton in the water helps monitor the effects of global warning. water helps monitor the effects of globalwarning. samples water helps monitor the effects of global warning. samples are packed off and sent to the analysed two scientists who cannot get here themselves.— scientists who cannot get here themselves. ., ., , , ~ themselves. coming to places like antarctica cost _ themselves. coming to places like antarctica cost a _ themselves. coming to places like antarctica cost a lot _ themselves. coming to places like antarctica cost a lot and _ themselves. coming to places like antarctica cost a lot and takes - themselves. coming to places like antarctica cost a lot and takes a i antarctica cost 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 terrorist ships are already here. season while the terrorist ships are already here-— already here. scientists also living in antarctica _ already here. scientists also living in antarctica for— already here. scientists also living in antarctica for many _ already here. scientists also living in antarctica for many months - already here. scientists also living in antarctica for many months of. already here. scientists also living i in antarctica for many months of the year. this presents its own unique challenges, logistics being one of them. this research base in livingstone island is temporary home

to around a0 scientists, but their supply ship has been delayed and they are running low on food. luckily, ourship they are running low on food. luckily, our ship was nearby and able to help. for them, it has been 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. what a magnificent sight, isn't it? let's hope it is tourism that is sympathetic to the environment around them. you are watching bbc news. it is going to be a cold and frosty night tonight and it felt quite chilly out there today, even though we had lighter winds and some sunshine, temperatures were only typically eight or 9 degrees which is below par for this time of the year and once the showers came along, those temperatures dropped quickly. still some wintry nice in the showers, but nowhere near as snowy, because each day gets

a little less cold and those showers are fading overnight tonight, skies will clear in many parts of the country and with light winds, temperatures will fall sharply, there will be a widespread frost tonight. quite a sharp frost in places getting as low as —7 and some of the frost hollows. high pressure keeping it fine and dry overnight and at the winds are not coming in from the north sea and for the east coast of england it will be a little less code and a weather front will bring cloud and rain from the north west and we start sunny and cold and frosty and cloud will increase on sunday as the wind picks up in scotland and northern ireland, we push rain down from the north in the afternoon. cloud will bubble up in england and wales, some sunshine, a few showers around, not as many as we saw today and those temperatures to creep up slowly to ten or 11 degrees. could be a bit warmer than that on monday, this weather front is taking rain south across the uk overnight and then following on from that,

we have this chunk of warmer air, it is what we call a warm sector, a lot of cloud but higher temperatures, we should start frost free on monday but it looks cloudy, rain and drizzle at times and a stronger wind. away from the far north of scotland, warmer air we have across the uk and temperatures reaching 1a or 15 celsius. a weather front is going to be pushing down overnight and it will move down, not much rain on that, but to the north of it, we have colder conditions to start on tuesday. along the weather front, we have this cloud and outbreaks of rain, most of the rain affecting northern ireland, pushing over the irish sea into the west of england and south west scotland. north of that, the colder air and cold enough for wintry showers in the northern isles, miles are in england and wales, temperatures around 15 degrees. very unsettled through the week ahead, wet and windy weather at times and just cold enough in the far north of the country to bring

the riks of some more snow. goodbye.

this is bbc world news, the headlines... hundreds of people have escaped the besieged ukrainian city of mariupol — but the red cross' evacuation efforts have once again been frustrated. they are spending the night en route and will resume their journey tomorrow. emmanuel macron held held his first rally of his french election campaign. he told around thirty thousand supporters he's fighting for social progress and to stop �*extremism' in french politics. hollywood actor will smith has resigned from the oscars academy after slapping comedian chris rock on stage during last sunday's ceremony. the academy says it accepts smith's resignation and will continue with their own disciplinary proceedings. today marks forty years since since argentina invaded the falkland islands. tributes are being paid

to those who served and died in the british overseas territory.
