a $2 trillion package to boost the us economy ravaged by covid. and we'll have an update from russia, where key opposition figure alexei navalny has announced he is going on hunger strike in protest over his treatment in prison. hello, and welcome if you're watching in the uk or around the world. i'm kasia madera. and stay with us for the latest news and analysis from here and across the globe. let's start in the us where the jury in the trial of derek chauvin has been shown new footage of george floyd, including police body camera video in the moments just before his death. the court also had to adjourn briefly after one witness broke down while giving testimony. the former police officer has pleaded not guilty to two counts of murder and one of manslaughter. aleem maqbool has this report, and a warning — some viewers may find material in this story distressing. derek chauvin on the right here watched with the rest of the court this now haunting footage, of george floyd dressed in black seen for the first time in the shop where the sad series of events began. a shop assistant, 19—year—old christopher martin, said mr floyd seemed physically well and in good spirits, if a little disorientated and high. george floyd is seen moving to the cigarette counter where he uses what is suspected to have been a forged note, though christopher martin accepted it, saying he thought george floyd wasn't aware of it being fake. the manager of the shop asked that the police be called. more footage showed officers pulling george floyd from his car and later being handcuffed and led further up the road. charles mcmillan was another eyewitness to take to the stand and his voice is heard in some of the most distressing video of the day. indistinct voices if you get in this car, we can talk! george floyd is soon seen being pushed to the ground by officers. indistinct voices mr mcmillan, do you need a minute? it's clear what happened that day last may has had a life changing impact on so many. a crowd soon gathered and among the bystanders was the young cashier who had alerted his manager about the fake note. what was going through your time during that time period? disbelief. and guilt. why guilt? if i had just not taken the bill, this could have been avoided. it's been hard for many to hear teenagers talk of their guilt over george floyd's death when the reminders of the actions of the man on trial are inescapable. aleem maqbool, bbc news. let's cross to minneapolis and the bbc�*s lebo diseko. an absolutely harrowing day today. yes, and even more harrowing the footage plate later on in the afternoon. there was a body camera expert who works for the minneapolis police and looks after their body camera department. in the defence played body cam footage from all four officers that were at the arrest scene of george floyd's arrest, and you saw from all the different angles the really harrowing pictures of that day. time and time again, you hear george floyd begging for his life, pleading with the officers — and i think that is what the prosecution will have wanted to achieve here, to have the jury wanted to achieve here, to have the jury leave at the end of the day with that footage in their mind, the four officers�*s body cam footage showing george lloyd in high levels of distress and just pleading for his life. —— george floyd. in of distress and just pleading for his life. -- george floyd. in this situation shows _ his life. -- george floyd. in this situation shows just _ his life. -- george floyd. in this situation showsjust how- his life. -- george floyd. in this| situation showsjust how difficult situation shows just how difficult it's been for the witness, when they're being reminded of this horrific event?

—— witnesses. tte: witnesses on the stand today horrific event? —— witnesses. tt2 witnesses on the stand today were really traumatised, two of them really traumatised, two of them really in particular. you spoke there about charles mcmillan, the 61—year—old gentleman who is a local gentleman who was just walking to the area when he came upon the scene and got involved. he had initially been pleading with george floyd to comply, but also remonstrated with the officers, saying, "you don't have to do this, you don't have to behave this way." and he just broke down on the scan. in the 19—year—old cashier saying when they take notes that had turned out to be counterfeit, it has to come out of their wages. counterfeit, it has to come out of theirwages. but counterfeit, it has to come out of their wages. but he had actually thought george floyd didn't look like he was doing that on purpose, maybe he should just pay for himself, so he thought of using his own money to cover the cost of that allegedly counterfeit note. he feels so much guilt that he didn't, you know, he says that if he hadn't reported what had happened, if he had just chosen to do things differently, may be george floyd would be alive. and you think, and 19—year—old boy carrying that amount of guilt with him, and physically just... of guilt with him, and physically 'ust... �* ., ., , just... and the whole world is watchin: just... and the whole world is watching these _ just... and the whole world is watching these events - just... and the whole world is l watching these events because just... and the whole world is - watching these events because of the painful memories they bring back. yes, i was speaking to a local pollster, she opened up her church to the protesters when george floyd died and was looking after them when some of the disturbances were happening here. and she said she feels that her city is heavy and there's a real feeling feels that her city is heavy and there's a realfeeling of feels that her city is heavy and there's a real feeling of pain feels that her city is heavy and there's a realfeeling of pain here. it's not the same kind of levels or numbers of people out on the streets, we are in coronavirus times and there are restrictions here. but there is just a fragility, she says, to the emotions people have here at the moment. to the emotions people have here at the moment-— the moment. indeed. thank you so much for bringing _ the moment. indeed. thank you so much for bringing us _ the moment. indeed. thank you so much for bringing us that _ the moment. indeed. thank you so much for bringing us that update i much for bringing us that update live from minneapolis. thank you. the french president, emmanuel macron, has put mainland france back into lockdown for four weeks from saturday. in a national televised address, he said all but the essential shops would shut, and people would again be asked to work from home. he said from next week schools would close for three weeks, with exceptions for the children of key workers. he also announced a vaccination programme, promising that by the end of the summer, everyone over 18 will be vaccinated. our paris correspondent lucy williamson reports. paris today is a tale of two cities. a sense of freedom in the streets. in hospitals, a sense of deja vu. with more than 5,000 patients in intensive care, france is already above normal saturation level. in this small paris unit today, all nine life—support beds were full. translation: the thing that worries | us a lot is that protective measuresl are not being respected. when the weather's good, we see people walking by the seine, all crammed together, or shopping in the market without any protection, and we know that in these kinds of situations, the government has trouble enforcing the restrictions. 79—year—old madeleine arrived here after refusing the astrazeneca jab. she didn't trust it with all her underlying conditions, she told me. but while waiting for the pfizer one, she caught covid. has it changed her mind about the astrazeneca vaccine? non, non. "no," she said. it's here in the capital's life—support units that pressure on president macron has been sharpest. some doctors have warned of an impending health disaster, saying they could soon be forced to choose which patients live and which die. tonight, mr macron admitted france needed to toughen the rules. from saturday, everyone will have to stay local and schools will close for up to a month. translation: we did everything we could to take these decisionsl as late as possible, and only when they became strictly necessary. that time is now. but i would also like to tell you this evening that, thanks to the vaccine, we can see the way out of the crisis. with transfers from the worst—hit areas already begun, doctors have been calling for a third national lockdown. the light restrictions currently in place in areas like paris, they say, aren't clear or powerful enough. but these are the rules now being rolled out across france. we don't understand them any more. we're like, are we quarantined or not? we don't really understand, so we're going out without really knowing. but, yeah, what i think isjust, like, maybe it would be better to go home, but on the other side i want to be out. after weeks of criticism over his strategy, president macron is facing a nation divided, between those who say they can't face another lockdown and those who can't face another wave. lucy williamson, bbc news, paris. let's get some of the day's other news. pfizer says trials of its covid vaccine in children aged 12—15 show 100% efficacy and a strong immune response. it said the teens involved in the trial had a higher antibody response than adults and the jab was well—tolerated. the company says it now plans to seek regulatory approval from world bodies in the hope that youngsters can receive the jab before the next school year begins. a major report has concluded that race and racism have become less important factors in explaining social disparities in the uk. a commission was set up by the government in response to the black lives matter protests, to investigate racial inequalities in education, employment, health, and criminaljustice. the international criminal court has upheld the acquittal of ivory coast's former president, laurent gbagbo, who'd been accused of crimes against humanity. he was the first head of state to stand trial at the icc. mr gbagbo had been cleared of charges in connection with post—electoral violence in the west african nation more than a decade ago. the prosecution had appealed against the decision. president biden has unveiled an infrastructure investment plan on a scale not seen in the united states in decades. the $2 trillion package aims to modernise roads, repair bridges and promote climate initiatives — in the process creating millions ofjobs. it's expected to be financed by a tax increase on corporations. the plan is likely to face a fight in congress where republicans have voiced opposition. what i'm proposing is a one—time capital investment of roughly $2 trillion in america's future, spread largely over eight years. it will generate historicjob growth, historic economic growth, help businesses to compete internationally and create more revenue, as well. they're among the highest value investments we can make in the nation, investing in our infrastructure. put another way — failing to make these investments adds to our debt and effectively puts our children at a disadvantage relative to our competitors. that's what crumbling infrastructure does. the imprisoned kremlin critic alexei navalny says he is going on hunger strike because he is not receiving medical help for back pain and problems with his legs. in a statement issued through his lawyers on instagram, mr navalny said, he wanted russian law to be observed and for a doctor of his choice, to come and treat him. mr navalny was sentenced to two years and eight months injail for breaking his parole terms, in connection with a previous fraud sentence. sarah rainsford in moscow has more. well, this is a real escalation of a situation by alexei navalny. he's announced of this hunger strike saying it's the only kind of protest that a prisoner can actually make. so he's calling for the authorities to allow a specialist doctor to come see him and for medication to be prescribed for him, because he says he's in really quite severe pain not only in his back, but also now radiating down both legs. and in fact, in a letter he wrote to the head of the prison where he's being held, he even made a joke, he said, "fine, i can do without one leg, but not both of them." but obviously this is a serious situation, as mr navalny pointed out, he was poisoned just last year. so he's really concerned about what these symptoms might actually be down to and, in fact, what his chances of recovery could be. so he's really drawing focus now to his plight, essentially. until now, the kremlin has been asked about mr navalny�*s condition, it's always said it's nothing to do with the kremlin, this is up to the prison authorities to deal with — and the prison authorities have said that mr navalny�*s condition is satisfactory. but certainly, if the kremlin wanted or thought that alexi navalny, having been sent to prison, would be silenced or removed entirely from the political scene here, that clearly hasn't happened. stay with us on bbc news. still to come: stirring up painful emotions. how derek chauvin�*s trial has struck a nerve in america's black community. the accident that happened here was of the sort that can, at worst, produce a meltdown. in this case, the precautions worked, but they didn't work quite well enough to prevent some old fears about the safety features of these stations from resurfacing. the republic of ireland has become the first country in the world to ban smoking in the workplace. from today, anyone lighting up in offices, businesses, pubs and restaurants will face a heavy fine. the president was on his way out of the washington hilton hotel where he had been addressing a trade union conference. the small crowd outside included his assailant. it has become a symbol of paris, -

headlines... the third day of the derek chauvin murder trial features new security camera footage and emotional testimony from witnesses. the french president, emmanuel macron, has announced a fresh national lockdown, but said there was now light at the end of the tunnel. tensions on the korean peninsula are bubbling again after a relatively calmer period toward the end of the trump administration. some view the recent missile launches by north korea as provocations aimed to test the mettle of the new biden administration and its commitment to defending its ally south korea. let's remind ourselves of the latest developments coming from north korea. on 16 march, the influential sister of kimjong—un warned the us not to "cause a stink" — criticising the us and south korea for conducting joint military exercises, which take place annually. the white house said it had been trying for weeks to make diplomatic contact with north korea. on 21 march, north korea fired two short—range cruise missiles into the yellow sea, but these do not flout un security council resolutions. us defence officials called it "business as usual". just days later north korea fired two ballistic missiles into the sea to its east, pyongyang is banned from testing ballistic missiles under un security council resolutions, and joe biden warned that there would be "responses" if launches continued. i'm joined now byjean lee, who has covered north korea extensively as an ap journalist and is now the director of the korea centre at the wilson centre in washington, dc. what is north korea playing at? what is your assessment of this ratcheting up of the pressure? tt is ratcheting up of the pressure? it is startin: to ratcheting up of the pressure? it is starting to feel _ ratcheting up of the pressure? te 3 starting to feel like deja vu. it is still very early in the us presidency, and i think what we are seeing is two months into his presidency, north korea becoming a bit impatient with the fact of the biden administration has not revealed its north korean policy. the biden administration is putting its finishing touches on that policy, we should see that in a matter of days, if not in the next few weeks. but what i think we are seeing is north korea trying to influence policymaking not only in washington, but in seoul, tokyo, beijing and elsewhere. [30 washington, but in seoul, tokyo, beijing and elsewhere.— washington, but in seoul, tokyo, beijing and elsewhere. do you think the thinkin: beijing and elsewhere. do you think the thinking is _ beijing and elsewhere. do you think the thinking is when _ beijing and elsewhere. do you think the thinking is when it _ beijing and elsewhere. do you think the thinking is when it comes - beijing and elsewhere. do you think the thinking is when it comes to - beijing and elsewhere. do you think the thinking is when it comes to the biden administration, the new president has his hands full with the pandemic and everything else coming in, so is ita the pandemic and everything else coming in, so is it a snub orjust basically he's been pretty busy? t basically he's been pretty busy? i think it's very complicated. basically he's been pretty busy? t think it's very complicated. those of us who are watching the korean peninsula have been bracing for provocation because north korea does know that bad behaviour is the most effective method to getting on the us president's radar, and we have been concerned that president biden's priorities right now are this global pandemic and economic fallout. but i think it's more complicated, and i think that's because the biden administration is first of all dealing with the nuclear arsenal and a ballistics nuclear arsenal and a ballistics nuclear arsenal and a ballistics nuclear arsenal in north korea that is far stronger in 2021 that it was frankly in 2017 when donald trump took office. so it's a very different game. and also, i think they are looking to bring the whole region into the strategy instead of this bilateral us— north korea summit diplomacy. they're looking for more comprehensive, collaborative strategy that involves south korea, japan, and possibly china, and that takes time. they have to rebuild those relationships and try to get all those on board. sojudging by that, in a and try to get all those on board. so judging by that, in a sentence, we don't expect a meeting between the two?

i am sick of standing this ground. i will not call your recklessness the law. what does black exhaustion mean to you? black exhaustion for me is the tiredness you feel when the answer feels so simple and right there. and your country has a long history of pretending like it doesn't exist. it seems to me like... america's new project is to always keep black liberation in the future. this is kind of like ground zero of where all the protest turned into uprisings, turned into destruction. this local activist and film—maker has lived through and documented many disappointments for this community. we have been here before. we have been here where police have been charged, like in philando castile's case and they have gotten away with it. and we have been there where they have not been charged at all. and we walked away disappointed in the justice system, so i think that kind of trauma over and over again building up, it does wear you out, it does make you tired. these are the names - of the known victims of police brutality in minnesota. there are 420 names listed. this is deborah watts. her cousin, emmett till, was lynched in 1955 for offending a white woman. he was only 1a. the man charged with killing him were acquitted and his accuser recanted her false testimony. from watching the case of emmett till who was your cousin, 66 years ago, every successive black pain, black trauma, black death that is on the news, how do you react? the wound is open again. and until we getjustice, truth and accountability, and some sort of reform, i it is not going to heal over. we cannot use hate as a way to fuel us. j we have to use hope as a way to fuel us, hope with action. _ hope with expectations and demands. it has taken my father's time, my mother's time... for so many in america, they just want to wait any longer. —— they just won't wait any longer. how much time do you want for this progress?! we've been talking about this because the court has been examining cctv footage ta ken of because the court has been examining cctv footage taken of george floyd shortly before his death, as the murder trial of former police officer derek stove and enters its third day. —— derek show ben. hello there. despite there being more cloud around across southern britain on wednesday, we still manage to make highs of 2a celsius in the sunny spells across the far southeast. for today, though, it is cooler and fresher for most areas. that is away from the southwest and south wales. here we have the warmth just holding on for one more day, but this area of high pressure with its chillier air starts to topple in from the northwest. that breeze will be noticeable across the north sea coast, feeding in quite a bit of cloud here. elsewhere, though, we should see the clouds breaking up to allow for plenty of sunshine. probably the best of the sunshine, again, will be across this southwest corner. we change the wind direction, though, that northeastrly, like i mentioned, cool down the east coast. it will be a different feeling wind from the warm southerlys which we've had over the last few days. temperatures struggling to get above 7—9 celsius across the north sea coast. 16—20 celsius, though, in the southwest — that's where we will have the last of the warmth. but that warmth ebbs away through thursday night, and into friday morning, the cold air is with most of us, and we will actually see some frost, particularly for the far north of england and in toward scotland. low single digits for the rest of england and wales. 0ur area of high pressure really builds in for friday. so there will be a lot of dry and settled weather, but it is chillier air blowing down on a north—north easterly wind, and again, that northeasterly wind will feed in more cloud to northern and eastern parts of the uk. so it will stay rather chilly and grey here. with more shelter to the south and the west, this is where we will see the best of the sunshine. so, temperatures into the afternoon could reach 12—13 celsius, 9—10 celsius closer to the east. these temperatures actually closer to the seasonal average. through friday night, though it's going to be a colder one for most with the widespread frost particularly central, northern and western areas. now, as we move into the easter weekend, although high—pressure will bring a lot of dry and settled weather, it will feel cold, and then as we head on into easter monday, we will see a real arctic blast which will bring some wintry showers to our shores as well. so our area of high pressure dominates for saturday and sunday, then allows this low—pressure to sweep down from the north through sunday into easter monday. and that will open the floodgates, a much colder blast of air than what we will have for the start of the weekend. and like i mentioned, that will be feeding into some snow showers, maybe to northern and western coasts on monday. but temperatures will still reach the low teens celsius with the sunshine on saturday and sunday. this is bbc world news, the headlines... 0n the third day of the trial of the white police officer accused of killing george floyd, prosecutors have played cctv and surveillance footage of him shortly before his death. the white officer, derek chauvin, has pleaded not guilty. president biden has unveiled a two trillion dollar infrastructure plan which he hopes will lead to the biggest investment in american jobs since world war two. the focus is on modernising roads and bridges and promoting climate initiatives. french president emmanuel macron has announced a new four—week national lockdown from saturday. he said all but essential shops would close and home working would become the norm. checks will be stepped up to stop public gatherings. russian opposition leader alexei navalny has gone on hunger strike at the penal colony to demand proper medical treatment. he has complained of not receiving medical help for back pain
