this is bbc news with the latest headlines for viewers in the uk and around the world. the challenges at the us—mexico border take centre stage asjoe biden holds his first presidential press conference. the overwhelming majority of people coming to the border and crossing are being sent back. the only people we are not going to let sitting there on the other side of the rio grande by themselves with no help are children. strong words from brussels after eu leaders met for talks — astrazeneca must "catch up" on vaccine deliveries for the eu before exporting elsewhere. learning to live with the virus — landlords say plans for vaccine passports to enter pubs are unworkable. retail giants nike and h&m are facing a backlash in china after they expressed concern

about the alleged use of uighur forced labour in cotton production. hello and welcome if you're watching in the uk or around the world — and stay with us for the latest news and analysis from here and across the globe. president biden has held his first news conference as president of the united states. the 78—year—old said he expected to run again in 202a. mr biden announced a doubling of his vaccination target in his first hundred days to 200 million doses, and defended his policies on immigration and gun control. here's our north america editorjon sopel. no fanfare, no hail to the chief, no fight with journalists... please, please, sit down, thank you.

no one even called another "beauty". this is about as different from the trump era as you could get, though the memory was there. my predecessor, oh, god, i miss him. he wanted to parade achievements — the speeding up of vaccine delivery, the boost to the economy from his stimulus package and a new tone for political debate. the third reason i said i was running was to unite the country, and generically speaking, all of you said, "no, you can't do that." well, i've not been able to unite the congress but i'm uniting the country. but on the southern border, his problems are growing as quickly as the number of immigrants trying to cross into the us is swelling — the first real test for the president. the idea that i'm going to say, which i would never do, if an unaccompanied child ends up at the border, we'rejust going to let him starve to death and stay on the other side... no previous administration did either, except trump. i'm not going to do it. he's also talking tough over gun crime, where,

in the last week, there have been two terrible mass shootings. but what can he do? not much, it would seem, given the votes in congress and that means on these big issues, he could look weak. abroad, he said that north korea was still the biggest problem. but i'm also prepared for some form of diplomacy, but it has to be conditioned upon the end result of denuclearisation. there would be no big changes on china policy. doesn't have a democratic with a small d bone in his body but he's a smart, smart guy. and would he be going along with donald trump's timetable for getting american troops out of afghanistan? we will leave, the question is, when we leave. sir, do you believe, though, it's possible we could have i troops there next year? i...i can't picture that being the case. this news conference, in terms of style, represented a complete break with the donald trump era.

but in terms of substance, say it quietly, not so much. on policies like the border, globalisation, china, afghanistan — it was all quite similar. it may not have been full—throated america first but there were strong hints of it. jon sopel, bbc news, washington. the head of the european commission ursula von der leyen has said that astrazeneca must "catch up" on vaccine deliveries for the eu before exporting its vaccine supplies elsewhere. european leaders have been meeting to discuss tightening export controls on vaccines. her predecessorjean claudejuncker has urged the eu to pull back from a vaccine war. from brussels, here's our europe editor, katya adler. prague is remembering its dead — simply, painfully. with one of the highest covid fatality rates in the world, the czech republic, like many other eu countries, is in the grip of a third wave.

vaccines are in short supply. national roll—outs like here in belgium in disrepute, the eu's credibility on the line. eu leaders have been meeting remotely today to discuss how to secure the eu's vaccine supply, ensuring companies deliverjabs promised and, controversially, potentially blocking vaccine exports to vaccine—producing countries like the uk, which have an already advanced roll—out. we want to make sure that europe gets its fair share of vaccines, because we must be able to explain to our citizens that if companies export their vaccines to the whole world, it is because they are fully honouring their commitments and it does not risk security of supply in the european union. what started as a health crisis now has political overtones here —

especially after brexit. eu leaders are under huge pressure to act. their voters increasingly frustrated about a lack of vaccines and fearful because of a third wave of the virus. but not all of those leaders want vaccine export controls. tonight, the commission is trying to persuade them otherwise. it says since december the eu has exported 77 million jabs to wealthy countries. 20 million to the uk, i'vejust been told, without receiving one back in return. intentionally provocative, perhaps. the commission now insists brussels was key in making the uk's vaccine effort a success. some eu countries say they prefer never to use vaccine export controls for fear of disturbing international relations or supply chains. france is more hardline. but today, president macron admitted the eu had made mistakes along the way.

translation: we didn't go fast enough, strong enough, - it's absolutely true. we thought the vaccine would take time, but we are catching up. not a moment too soon for europeans languishing in lockdown, decimating their economies. here in britain members of parliament have voted to extend emergency coronavirus powers in england until september. meanwhile, plans for so—called vaccine passports to allow people back into pubs and entertainment venues are under discussion by the government. 0ur uk political editor laura kuenssberg has more. eager to get to the bar? forget proving your age, what about proving you had a jab or negative test to get a pint? the bell and cross near stourbridge has already spent thousands to get ready to serve outside. ijust think it's a really, really bad idea. the checks we had to do anyway when we were open were extensive. it creates a huge amount of extra

work, which meant an extra increase in staff costs. also the stress of the staff, because we were meticulous in following these instructions. borisjohnson paints himself a freedom lover, but regular covid checks are being considered as the government wrestles with how to safely open the economy. but it's not easy to grab onto straightforward solutions. i need to get a haircut. are you booked in for april the 12th? for the pub? yes. no, for the haircut! whether haircuts or this issue, pub passports, there's a lot to plan. you've got to be careful how you do this. you might only be able to implement a thorough vaccination passport scheme, even if you wanted such a thing, in the context of when absolutely everybody had been offered a vaccine. so, there are complexities, moral complexities, ethical problems that need to be addressed. hang on though — this was only last month. what i don't think we will have

in this country is, as it were, vaccination passports to allow you to go to, say, the pub. that view is shifting, though. this is one of downing street's locals and, like everywhere else around the country, it hasn't seen a punter for months. the government isn't planning to make vaccines compulsory, or force you to do a test every time you leave the house. but they are looking at how pubs, restaurants, venues, football grounds or workplaces can use covid checks to help open up and let us back in. officials are considering if pubs and venues could stop social distancing if they carried out covid tracks. but they'd leave the decision to do so up to individual firms. it's not really for the government to abdicate its responsibility and leave it to the private sector to decide the rules, and then take the flak for what may be very unpopular decisions.

with so many doors still shut, this suggestion has riled a small but noisy group of tory mps, already unhappy that ministers asked them to extend the government's sweeping powers. unless you fight for freedoms every day, they end up being taken away from you. after months of denial, now indeed it will be i the case that you will have - to provide your vaccination bona fides when you go to the pub. we, as conservatives, should be very careful not to constrain the private sector in how they choose what customers they have. covid checks wouldn't be used until everybody has been offered a vaccine and will not affect grand plans to reopen outdoor venues next month. but as restrictions roll back, thing is clear, the world won't look the same. laura kuenssberg, bbc news, westminster. let's get some of the day's other news. the prime minister of poland — mateusz morawiecki — has warned that the country's health system is on the verge of being "overwhelmed" as it struggles with a surge in new coronavirus infections.

pre—school childcare, diy stores and hairdressers will close for two weeks from saturday. churches will remain open for easter but the numbers who can attend mass will be limited. from sunday, anyone flying into germany will need to show a negative covid result before boarding. it comes after the spanish island of majorca was taken off germany's "high risk" list last week and airlines scheduled hundreds of extra flights to cope with the surge in demand. germany is battling a sharp rise in coronavirus infections, fuelled by new variants. mexico has become the third country to reach a coronavirus death toll of 200,000, after the united states and brazil. the president said the armed forces will be brought in to help with the roll—out of covid—i9 vaccines. community groups have been urging people to avoid social gatherings over easter. nike and h&m are among major clothing retailers facing a backlash in china after expressing concern about allegations that uighurs

are being used as forced labour in the production of cotton. it's estimated that a million mostly muslim uighurs are detained in camps in the north—west region of xinjiang. bbc investigations have gathered first—hand testimony of forced labour, and evidence that detainees have been raped and tortured. china denies the claims and says the camps are vocational training schools. our world affairs editor john simpson reports. the stories about the uighur camps have spread around the world. after reports of forced labour in the cotton fields of xinjiang province, international companies like h&m, nike and muji injapan have all reacted strongly and that's brought an angry backlash from china, which says the accusations about the uighurs are lies.

today, in the turkish capital, ankara, the chinese foreign minister, wang yi, has come to talk to president erdogan. there were protests by uighur exiles. turkey has strong ethnic and cultural links to the uighurs and it's always given them refuge. a uighur woman who went to turkey to study, recently found that her entire family back in xinjiang had been arrested — father, mother and two brothers. when i asked them why, they said my family members think they might have an intention to attempt terrorist activities. 12 years ago, when china clamped down on rioting among the uighurs, the turkish leader, recep erdogan, called it genocide. it's not a word he'd use today. china is pressurising turkey to ratify an extradition treaty, which would mean handing over any uighurs china wants returned.

china isjust far too powerful economically and too many trader deals all came with the terms and conditions. so, effectively, china's bought off turkey? yeah. just like all the other countries, many arab countries and muslim countries, like pakistan. and they're not speaking up at all. turkey's economy has suffered badly from covid, which has brought a collapse in tourism, its biggest foreign currency earner, and since the west isn't doing much to help, mr erdogan has turned to china, which offers turkey everything from covid vaccines to weapons. the turkish embassy hasn't replied to our questions about this. the fact is, turkey is really up against it. it's got its serious economic

problems and it's moving away from its old friends in the west. china's only too happy to step in, but part of the price for that would be to keep quiet about the uighurs. i really want to see them again. i'm not sure if i can or not. they spent their whole life... to offer me a good education, to have a good life. there's no shortage of stories like this, but turkey doesn't seem to complain about them publicly any more. john simpson, bbc news. stay with us on bbc news, still to come — a painting by vincent van gogh sells at auction in paris for more than 13 million dollars.

this is bbc news, the latest headlines. the challenges at the us—mexico border have taken centre stage atjoe biden�*s first presidential press conference. a virtual summit has ended with european union leaders emphasising their wish to make sure the eu gets its fair share of coronavirus vaccines. with the chase for vaccines happening around the world, so too has come the emergence of vaccine—related fraud. it's on the rise in australia, according to the country's competition and consumer watchdog. data from the commission shows that scams have increased more than twofold since january last year. in the state of queensland alone, people have lost more than 2.3 million dollars — through scams that have either intimidated them with arrest, or threatened their lives. joining us from canberra

is delia rickard, the deputy chair of the australia competition and consumer commission. this sounds, talk us through some of the scams people have experienced. they are terrible and what we know about scammers is they always take advantage of current events and build scams around them. in the early days of the pandemic we saw a range of scams pretending to be the government, talking about having to pay to go and get a covid test which you don't have to do in australia, playing on people's fears. now the vaccine roll—out has started, what we are starting to see is scanned around the vaccine. we are seeing fake investment scams to invest in the pfizer vaccine and a range of surveys where they say, we will pay you $90 to do this survey about the vaccination process and they are reallyjust vaccination process and they are

when anderson antulio set off from his village in the guatemalan highlands, he no doubt carried its name — nueva esperanza, meaning "new hope" — in his heart. butjust i6 and travelling alone, hisjourney ended in the worst possible way. he was brutally murdered just miles from the us border. his parents were still trying to comprehend the decision to allow their eldest child to leave unaccompanied on the treacherous trip north. the sad truth is that anderson's grim end won't dissuade other teenagers in his community from attempting the same trip — not even in his own family. translation: working the land here, i'd only make about $6 a day. - that doesn't go far. i know i'm young, but if i don't go, i'll have to work in the fields with my father, where often there isn't work every day, sometimes just 2—3 days a week.

families in these highland communities say their young people aren't just leaving, they're being forced out — obliged to leave their homelands through a potent combination of high unemployment and poor soils, damaged by climate change and drought. it's little wonder that many see no alternative than to pay for a people smuggler and to head north. opportunities, if you're young in san marcos, are scarce. the players for the third division local club dream of playing in europe someday. but the likelihood of breaking through is slim. most of these players have spent the morning working the fields before training. amid the town's grief for its lost children, the authorities can provide few incentives for young people to stay. in one of latin america's poorest nations, there are minimal resources for education or employment. translation: the migrant hasjust two options - - reach their destination

or die trying. that's the only dream they have at this time. it's no use me telling a young person, "hey, when you get there, you'll be washing plates and sleeping in a flea pit." they're not thinking about that. and until there's hope of something beyond just more grinding, exhausting poverty here, most young people will opt to flee. will grant, bbc news, san marcos, guatemala. a painting by van gogh that had been held in a private family home for more than 100 years has been sold at auction for more than 13 million euros. street scene in montmartre was painted by the artist in 1887 while he was living in paris, and captures the social changes that were taking place in the area at the time. our paris correspondent lucy williamson, who has been to see the painting,

was watching today's auction. and now we have arrived at lot six... after more than a century hidden from public view, this painting was sold twice today. the first bid won by an online buyer whose offer came in just as the hammer fell. but there was a problem with the sale, and the auction had to be rerun. the painting finally went to a buyer in london forjust over 13 million euros, several million lower than the first time around, but still one of the highest prices ever paid for work from van gogh�*s paris period. the artist only lived here for a couple of years, during which time he painted many scenes from around montmartre, then in transition from a sleepy rural area outside the city to a vibrant bohemian suburb.

the painting, hidden away in a private collection for 100 years, shows a couple walking along a rural lane in front of a windmill. nearby, the top of a fairground carousel peeks through the trees. but this picture also tells the story of van gogh�*s own artistic transition — his colours becoming brighter and his tell—tale brush strokes beginning to appear. lucy williamson, bbc news, paris. a reminder of our top story.... the us president, joe biden has promised to deliver 200 million coronavirus vaccinations within the first hundred days of his administration. in his first news conference since taking office, mr biden dismissed suggestions of an immigration crisis at america's southern border. he said he would run for re—election in 202a. lots more on our website and i'm

available on social media. thank you for watching. available on social media. thank you forwatching. bye—bye. hello there. the weather will be turning much colder today. we look at the temperatures we got to yesterday, in the warmer spots we had highs of around 15 celsius, for example, in sheffield. today, those temperatures quite widely across the uk down by about five celsius. from 15 to about ten later this afternoon. the change is brought about by an area of low pressure, this one here, and there are a couple of weather fronts on it. the first one in imposter bringing in a little bit of rain eastwards. the second one is the cold front and it is behind that that the colder air will be spreading its way in across the uk. over the next few hours, ourfirst band of rain moves from wales across into central and western england. our main band of rain, our cold front, will be bringing wet weather and gusty winds to scotland, western parts of wales and northern ireland as well.

through friday morning, this band of rain will push eastwards and only really reaching east anglia and southeast england in the afternoon. so there will be a bit of sunshine or a time. behind that, some sunny skies but also plenty of showers. the showers will have hail and thunder mixed in across northwestern areas where it will feel particularly cold. highs of seven celsius and factor in the brisk wind and it will feel colder than that. in fact, through the weekend, i think it will stay on the windy side, rain around as well. we start off with a risk of icy stretches across higher parts of scotland and northern england because there may well be some snow showers here through friday night. icy conditions. sunshine for a time but further west the cloud building in and eventually outbreaks of rain spreading to northern ireland, perhaps western scotland towards the end of the day. blustery and still quite cool, temperature about nine or 10 celsius through saturday afternoon. into saturday night, more outbreaks of rain, particularly across northern areas of the uk with the rain turning heavy at times.

the weather front become slow—moving somewhere across northern ireland and northern england and north wales. to the north, cold air in scotland, so sunshine and a few showers, and to the south across southern parts of england and wales, temperatures will not be quite so low. highs of around 13 or 1a celsius. and that trend to slightly milder conditions continues into monday. for many of us it will be a much milder day with temperatures as high as 18 celsius but there will still be rain around across the north and west of the uk. that is your weather.
