welcome to bbc news. our top stories: four minneapolis police officers are sacked over the death of an african—american man pinned down in the street by his neck. for the first time, twitter labels one of donald trump's tweets as misleading. a special report from a london intensive care ward and the doctors who fear a second wave of coronavirus. i suspect that their cases willjust rapidly rise again. and costa rica becomes the first central american country to legalise same—sex marriage.

hello to you. to the united states first, and an investigation is under way in minneapolis into the death of another black man in police custody. four officers have been sacked. the victim has been named as george floyd. video has emerged showing a police officer kneeling on his neck in the street for some considerable time. this report from nada tawfik contains distressing images. a disturbing scene caught on camera by witnesses incensed over the police‘s actions. bro? the 10—minute video shows george floyd pleading with officers who have him restrained on the ground. one of them using his knee to pin the man down by his neck. clearly in distress, he tells the white officer he can't breathe and is in pain. the crowd tries to help and grows increasingly concerned and frustrated. when george floyd appears motionless, bystanders question why he isn't being given urgent medical attention. seven minutes in to the video, an ambulance arrives.

he's put on a stretcher — still handcuffed — and taken to hospital. at a press conference, the minneapolis police department offered their version of events. they said they were responding to a crime and that the man appeared to be under the influence. he physically resisted officers. officers were able to get the suspect into handcuffs and officers noticed that the male was going into medical distress. officers called foran ambulance, he was transported to hennepin county medical center, where he died a short time later. mayorjacob frey said that four of the officers involved have now been fired after initially being put on paid leave. the fbi is also investigating the incident. being black in america should not be a death sentence. for five minutes, we watched as a white officer pressed his knee into

the neck of a black man — for five minutes. when you hear someone calling for help, you are supposed to help. this officer failed in the most basic human sense. the viral video quickly sparked outrage. yesterday, what we saw was a black man who was lynched. right? they didn't use rope, he used his knee. and that black man, mr floyd, said, "i cannot breathe." minnesota prides itself on being progressive and being the north. but this is thejim crow north, and we demand justice. put your hands behind your back! i can't breathe!

for many, this is a case of history repeating itself. millions protested in 2014 after eric garner, an unarmed black man in new york, died after being restrained by police. his repeated plea of "i can't breathe" also captured in cellphone footage, became a rallying cry at demonstrations against police brutality against african—americans. there are sometimes investigations, but many feel there is rarely any accountability. nada tawfik, bbc news. let's get more now on that death in custody from the civil rights activist, podcaster and author deray mckesson. he's in new york. good to talk to you. like many other people without fail i listen every week to the podcast you do every week. i think is a really crucial briefing. i have heard you so many talk about the deaths of lack men particularly in police custody. when you heard about the death of george floyd, when

you saw the video, when you heard that phrase, i can't breathe over and over, your reaction was what? it was all too familiar. for context, a third of all people killed by a stranger in the us, actually killed by a police officer, and covid, people are locked down, there are low levels of crime happening all across the country. we have never seen before. still, the police actually killed and shot at the same rate in march and april 2020 as they did in march and april 2019. so there was no break in it. in minneapolis, we saw this video, it was deja vu for so many of us who have been tracking these incidents since 2014 and before. here is the thing. people are heralding the four officers being fired, but in minneapolis, half of officers who get fired and rehired. we will actually see if these firings stick and the

only good news comes out this moment is that in minneapolis because of the work of incredible activists and organisers in minneapolis they have a change to the police contract in 2016 that required officers to intervene if they see their partner or another officer engaged in wrongdoing, and that is actually how those three officers who just stood there and watched, that how they got fired. it is clear isn't it for whatever reason that a lot of police officers approach and encounter with a black man, even an unarmed black man, even an unarmed black man, even an unarmed black man expecting quite a serious level of violence, rightly or wrongly. what is the process there and how can that process there and how can that process be changed? it is interesting. i don't have a better way to say it besides it is racism. that is the only thing that helps us explain what it means, that you get a set of officers, normally white officers who approach a black person who is not a suspect, not done any wrongdoing, not

engaged in wrongdoing, but the suspicion of wrongdoing is enough for so many offices around the country, and we see these cases pop—up time and time again. you think this case, saw a video. think about the 300 other people killed in 2020 in the united states and you didn't see a video of them, you didn't see a video of them, you didn't see a video of them, you didn't see a whole set of people standing around. they killed him, they put... they restricted his airway in the middle of the day around a whole host of people, no shame, wasn't nervous. that is wild. i am hopeful that this will lead people to think more about systems and structures. you think about places like oregon, they have a law that says an officer can use deadly force if they think you just committed a felony or about to commit a felony. what is that even mean? across the country we really have left the police unchecked andi have left the police unchecked and i will tell you marys, said accou nts and i will tell you marys, said accounts at —— city council

people, governors are afraid. they will tweet about it but they will not stand up to the police. yes, what other chances of things changing? you have pointed out many times the police unions are very powerful, you pointed out that a lot of the statistics in which these encounters are are just wrong. they have been misinterpreted. there may be a lot of people watching who think i am worried about crime, worried about all sorts of things, iam worried about all sorts of things, i am happy to see a lot of support, funding go into police departments. they want more of it if anything. it is interesting. in america, and police say they solve a climb, that means they got the bad quy: that means they got the bad guy, the person got convicted. in america solved means they made at least one arrest. i don't even know what that tells you. the police are not engaged in some amazing sort of work to change communities like the data doesn't even show if that is true. we know the safest communities other communities with more resources, not the communities with more police.

arbitrators are big, police union contracts are big. we have to work on the nitty—gritty stuff. we know two things that actually do change police behaviour. the rules around discipline and then it is the rules around when you can use force. those are the only two things. everything else is interesting, body camera, restraining, that is interesting. the data does not support that these behaviours are changing. imagine if the worst are changing. imagine if the woi’st consequence are changing. imagine if the worst consequence of you doing anything would be maybe a reprimand, maybe getting fired, and they get a job at the next police department. the police know that structurally it is ha rd to know that structurally it is hard to hold them accountable. think about new york, the mayor in 2016 lifted the ban on shooting at moving vehicles and lifted the requirement that minimal force lifted the requirement that minimalforce had to be used during arrests. that happened in the midst of protests. we have a lot of weak politicians who will tweet about trauma when it happened but won't follow up. thank you so much

for talking to us. good to be here. twitter has for the first time prompted readers to check the facts relating to a tweet by president trump. the social network has placed a notification under a posting in which mr trump criticises plans to expand the use of postal ballots in november's election, which he says will lead to voterfraud. the notification directs readers to a page with news articles and information from fact checkers debunking the claim. our technology reporter zoe thomas is in san francisco. there a lot of people that are saying better late than never. of course, they are complaining about some of the tweets that the president has written in the past, which they say already violated twitter‘s policies. but what's happened now is that twitter has set new rules, where it says it won't remove comments or block the users who write certain things, but instead, when tweets

might be misleading, might give the wrong information, it's simply going to direct users to correct information, to explanations about what's being said. and this was a fairly successful policy for twitter when it came to information about covid—19 and misleading medical information by having a little notification on the bottom, get the facts about covid—19, they were able to spread correct information from the world health organization. and now, it's trying that out with election news and it's caught up the president in this new policy. there is a lot of speculation that president trump might get caught up, but twitter hasn't acted in the past, so it is impressive to the company taking some steps now. just briefly, zoe, there's something slightly cynical about what twitter is doing, isn't there? any other user who wasn't the president of the united states would have had their account closed a long time ago for what the president has put up. but it brings twitter enormous publicity and attention? it's a real balancing act they have to do. president donald trump has more than 8 million followers on twitter.

in fact, after the company decided to label his tweets as potentially misleading, he went on to twitter to say that it was stifling his free speech. so the company on the one hand really wants to hold onto him as a user and it's said in the past that president trump and other world leaders who've made misleading or even aggressive comments in the past, that they can make those comments even though they violate twitter‘s policies, because they're politicians and world leaders and that it's valuable for people to see what they're saying and for free speech to go on that way. so it's got to find a way to balance some of the things that he's making, some of the claims that are potentially false or harmful, while making sure that he stays online because they want to keep him and his followers on their platform. costa rica has become the first central american country to legalise same—sex marriage. a lesbian couple was the first to tie the knot in a ceremony that took place just after the new law came into effect on tuesday. more couples have already followed them. legalizing gay marriage was a campaign promise by president alvarado. same—sex marriage has faced some resistance in the country and recently 20 lawmakers

attempted to delay the law. earlier, i spoke to the president of costa rica and i started asking him about the internal opposition to this change. indeed, today is a historic day in costa rica, because it's about human dignity and human rights, not only about one specific right, defending human rights, it's defending all of them. so that is why we are happy as a costa rica community, as a whole. i was looking at the list. of course you know far better than me, there were other moves to legalise same—sex marriage in argentina, uruguay, ecuador, brazil, parts of mexico. but generally, costa rica is considered quite conservative. what's changed ? i think that's related mostly to democratic institutions. it was a rule of law passed through the constitutional

court. so, given that, it will open the path to making same—sex marriage legal in costa rica, given that it's recognised as a human right. ido i do believe that is very important. many people in the past years, the lgbt community in costa rica, not only were they bullied decades ago, but they were also persecuted even by police, having this recognition now. so to have the security of the law to the families and the children, this is to recognise the human dignity in front of the whole of society and is a strong message of equality. mr president, it was a close—run thing. just two weeks ago, more than 20 lawmakers tried to stop this happening, tried to put it off for 18 months.

and, in fact, it was never agreed in parliament, as i understand it. the constitutional court ruled the ban on same—sex marriage was unconstitutional, was discriminatory. the band had to be reinstated and never was. —— ban. do you expect challenges in the future? do you expect challenge? i do expect that, but that's the challenge is all of the open, free societies face. progress in democracy is not something we should take for granted. we should always defend human rights and that message is not only for costa rica. in today's world and in the context of multilateralism it's a reminder we need to keep fighting for free, open societies, democratic societies, we cannot take for granted human rights. i think that is a strong reminder in costa rica, but also around the world.

55. go, go, go! the professionalism of the team is stunning, years of experience is gathering around the bed as duality of time, the drifting of oblivious patient and the rush to save his life, merge into a tableau of our times. so, there is a final role of the dice. see you guys lift him up the dice. see you guys lift him up and! the dice. see you guys lift him up and i will put that down. this is a last resort, mainly by turning him onto his front back—and—forth air into his lungs, oxygen into his body, thatis lungs, oxygen into his body, that is all they can do. 0k, ready, steady, go. his lungs are getting worse,... and you are getting worse,... and you are preparing to talk to his family? yes, that is right. imagines the stress for the team, multiplied, every day,

four weeks. now you understand what the peak of the pandemic is like. are you all right? you have just come off shift? this woman bore witness to the dark days. it consumes you. it is what you'd think about when you go to bed, what you think about when you wake up, preparing for your next shift, relieved that the previous shift is over. you are sad. it is huge. a huge emotional burden. sometimes, it is hard to find light in the darkness. what you're about to witness, is what medicine can do. i'm going to take out your tube now.... this is do. i'm going to take out your tube now. . .. this is one of the defining moments in intensive ca re defining moments in intensive care unit. when a patient‘s ventilator tube is removed. it isa ventilator tube is removed. it is a procedure full of expectation and dread. we are going to pull out the tube.

world a re a group of experts around the world are developing guidelines to develop and apps to fight coronavirus. several american states and the uk are working on the technology and this could tell people if they have beenin could tell people if they have been in contact with someone with the virus. we collected a group of 26 experts across the world, including those from the uk and saw that there was a gap and how to think about ethics and how to think about ethics and governance of the new technologies as you said so many countries around the globe are trying to figure out how to use tools like contact tracing to help find our way out of the pandemic and with all the technology and work it didn't seem as technology and work it didn't seem as if there was enough ethics and governance work done so we ethics and governance work done so we had a rapid response effort and work for about a month and produced a report which was released today. that was a professor from john hopkins university. ever since the pandemic began,

countries around the world have been desperately trying to get hold of personal protective equipment, or ppe. that's the gloves, facemasks and gowns needed for doctors, nurses and carers. but what happens when these items, mostly made of plastic, get thrown away? the bbc‘s tim allman reports on the potential hazards of discarded ppe. in the waters off the coast of southern france, a perhaps in unexpected consequence of covid—19. this video, shot by an environmentalist appears to show disposable gloves on the seabed knee a resort. —— nearby a resort. not just seabed knee a resort. —— nearby a resort. notjust clubs, face masks also amongst the usual plastic pollution of the mediterranean. he is part of a group called operation clean sea, which describes the oceans asa sea, which describes the oceans as a heritage that has to be

respected. this is what he found during just two hours of snorkelling, dozens of plastic bottles a nd snorkelling, dozens of plastic bottles and lying in a row at the front, face masks and latex gloves. the demand for personal protective equipment has been, understandably, huge. country after cou ntry understandably, huge. country after country scrambling to get hold of as much of this stuff as they can. france alone is reported to have ordered in summer in the region of 2 billion face masks. much of it cannot be reused and some of it seems to be ending up discarded in the ocean. this has been described as a new form of pollution and there has been a warning that if nothing is done, we may end up with more face masks than jellyfish done, we may end up with more face masks thanjellyfish in the mediterranean. tim allman, bbc news. and you can get in touch with me and most of the team on twitter.

thank you for watching. hello there. there is plenty of dry and very warm weather in the forecast for the next few days. now, during tuesday, the very highest temperatures were found across eastern and southern parts of the uk, 27 degrees to the west of london. it was a bit cooler further north and west — not an awful lot cooler — but actually as we go through the next few days, we're going to see this area of high pressure, which is really dominating the scene, shifting a little further eastwards. now, the winds around the high pressure flow in a clockwise direction. so as the high shift eastwards, that will allow us to waft warm air northwards across just about all parts of the uk. but we start wednesday morning with the very mildest conditions across the south — 13,14 degrees in cardiff and in london. not quite as mild further north. but as we go through the day ahead, we're expecting lots of fine weather,

some spells of sunshine, a bit of patchy cloud towards the south and east of england, and certainly more cloud into northern ireland and scotland. and that cloud mayjust start to fringe some patchy rain in across the far west. those temperatures getting up to around 17 degrees there in glasgow. once again, 24 or 25 across parts of south wales, central and southern parts of england. now, as we go through wednesday night into thursday, we will see some outbreaks of rain pushing across the northern half of scotland, a weak frontal system pushing through. further south, it's dry with some clear spells on what will be a mild night for most — lows of six to 12 degrees. any early rain across scotland or nort—heast england will clear very quickly on thursday. and then, as you can see, increasing amounts of sunshine. bit of patchy cloud here and there, yes, but largely sunny skies. and at this stage, i think the highest temperatures will be found across western areas. so liverpool, cardiff, 25 degrees, but glasgow up to 22. a bit coolerfor some north sea coasts. now, as we get into friday, remember, when you look

at our maps and you don't see cloud, that means we're expecting sunshine. a lot of blue sky overhead on friday. again, those temperatures, 24, 25, 26 degrees. parts of south—west scotland getting into the middle 20s. still a bit cooler for some of those north sea coasts with a flow of air off the sea, but as we head into the weekend, high pressure does remain dominant. it should fend off this frontal system. yes, we mightjust see a little bit of rain fringing into the far north—west of scotland at times, but generally speaking, it's a dry weekend. and widely, it will be very warm, with those temperatures into the 20s.

this is bbc news.

the headlines: four police officers in the american city of minneapolis have been sacked over the death of a black man who was arrested and pinned down by his neck in the street. video of the incident shows george floyd groaning and repeatedly telling officers that he can't breathe. twitter has for the first time prompted readers to check the facts relating to a tweet by president trump. the social network has placed a notification under a post in which mr trump criticises plans to expand postal ballots, which he says will lead to voter fraud, despite evidence to the contrary. doctors at one of the hospitals hit hardest by coronavirus in the uk have spoken of their fears of a second wave of infections as the country's lockdown restrictions loosen. clinicians at the royal london hospital said they were better prepared than four months ago but are still very concerned.
