hello, i'm ros atkins, this is outside source. the us hasjoined indirect talks aimed at reviving the iranian nuclear deal — three years after donald trump abandoned it. presidentjoe biden wants to return america to the landmark accord — but tehran says it won't meet the us face—to—face in vienna — until sanctions are dropped. translation: if america's will, i seriousness and honesty is proven. it could be a good sign for a betterfuture, a future of peace and security. also in the programme — its day seven in the trial over the killing of george floyd — and another minneapolis police officer has given evidence that derek chauvin�*s actions during his arrest went beyond what was authorised.

if you could use the least amount, a lower level of force to meet your objectives, it's safer and better for everybody involved. russian police have detained the doctor ofjailed kremlin critic, in the uk, a trialfor children and teenagers for the vaccine has been put on hold. regulators investigate a possible link with rare blood clots in adults. we will talk to our health correspondent about that. russian police have detained the doctor ofjailed kremlin critic, alexei navalny as she tried to access the prison medical unit official say he's being treated in for respiratory symptoms. iranian and american officials have held talks in vienna, to try and revive the 2015 iran nuclear deal. donald trump pulled out of the agreement three years ago — now the biden administration wants to see if it's worth coming back in. and european officials are acting as intermediaries.

here's a spokesman for iran. translation: we are neither. optimistic nor pessimistic about the outcome of this meeting now. but we are confident that we are on the right track. and if america's will, seriousness and honesty is proven, it could be a good sign for a better future, a future of peace and security for the region in the world. ——and security for the region and the world. these are the reasons the iran nuclear deal was pursued in the first place. some world powers don't trust iran, and believe it wants nuclear power in order to build a nuclear bomb. iran denies this. in 2015 a deal was struck between iran and six other countries. iran would stop nuclear work in return for an end to to sanctions which are hurting its economy. but in 2018, president trump abandoned the deal and re—imposed sanctions on iran. now, president biden wants to rejoin, but both sides say the other must make the first move.

last week, biden�*s special envoy on iran, robert malley, told pbs: in other words — reverse what trump put in place. bethany belljoins us from vienna. bethany, can you help me understand the scope of these talks. what are their ambitions at this stage? weill. their ambitions at this stage? well, what happened _ their ambitions at this stage? well, what happened today _ their ambitions at this stage? well, what happened today in _ their ambitions at this stage? -ii what happened today in vienna in a luxury hotel, the remaining signet tarries to this deal, britain, france, germany, russia and china met. and then across the road in another luxury hotel, the american delegation is there. at the meeting today, they decided on work groups. they will have a workgroup that is

looking at how they can lift the sanctions and another group that is looking at how they can bring i run backin looking at how they can bring i run back in compliance in terms of its nuclear activities. so they have figured out out. they have heard her brush and diplomat here in vienna say there was a successful start. nobody knows quite how long this is going to go on for. nobody things it's going to be a simple process. there is a lot of trust that has been lost on both sides because of the us withdrawing from the dl and also because i run in response to the us withdrawing from the deal has overstepped. —— iran. it's limits on its nuclear work under the deal. so there is a great deal of lost ground to be made up right now. that could take a rather long time. but to be made up right now. that could take a rather long time.— take a rather long time. but is iran indicatin: take a rather long time. but is iran indicating that _ take a rather long time. but is iran indicating that if _ take a rather long time. but is iran indicating that if the _ take a rather long time. but is iran indicating that if the us _ take a rather long time. but is iran indicating that if the us were - take a rather long time. but is iran indicating that if the us were to . indicating that if the us were to withdraw those sanctions, it would be willing to comply with the

original terms of the deal? iran has said it once — original terms of the deal? iran has said it once all— original terms of the deal? iran has said it once all the _ original terms of the deal? iran has said it once all the sanctions - said it once all the sanctions lifted, that's not quite with the united states is talking about at the moment. i run's economy has been extremely hardly hit by the sanctions. —— iran. it wants them gone as soon as possible. the americans are talking about the sanctions that were there as part of the original iran deal. so there is a gap between the two at the moment and it will take a lot of pump gated negotiations to see what can be agreed upon that would satisfy both sides in order to get everybody back in line for the deal.— in line for the deal. bethany, thank ou ve in line for the deal. bethany, thank you very much _ in line for the deal. bethany, thank you very much indeed. _ in line for the deal. bethany, thank you very much indeed. that's - in line for the deal. bethany, thank. you very much indeed. that's bethany in vienna. ali vaez, iran project director at the think tank international crisis group in washington joins us now. do you agree that if the us was the country to pull out of this deal it should also be first to make the

move and to reverse those trumpet sanctions? that is the morally right thing to do, that is the morally right thing to do. but — that is the morally right thing to do, but you know, in the politics, morale _ do, but you know, in the politics, morale of— do, but you know, in the politics, morale of you doesn't mean much, and the reality— morale of you doesn't mean much, and the reality is_ morale of you doesn't mean much, and the reality is that if the biden administration was to move first and provide _ administration was to move first and provide iran— administration was to move first and provide iran with sanctions, it would — provide iran with sanctions, it would he _ provide iran with sanctions, it would be crucified in washington. 30 would be crucified in washington. sc what do would be crucified in washington. what do you would be crucified in washington. sr what do you think the biden administration should do bearing in mind it needs to play the politics in washington as well as keep all the signatories happy. you in washington as well as keep all the signatories happy. you know, the solution that — the signatories happy. you know, the solution that has _ the signatories happy. you know, the solution that has artie _ the signatories happy. you know, the solution that has artie been - the signatories happy. you know, the solution that has artie been said - solution that has artie been said publicly, — solution that has artie been said publicly, both sides would have to move _ publicly, both sides would have to move in_ publicly, both sides would have to move in parallel. so there needs to be a move in parallel. so there needs to he a road _ move in parallel. so there needs to be a road map which is the ultimate objective _ be a road map which is the ultimate objective of— be a road map which is the ultimate objective of the negotiations that are currently going on in vienna to basically— are currently going on in vienna to basically define the steps that each side has _ basically define the steps that each side has to take, match them with one another with the end of objective on which both sides agree, which _ objective on which both sides agree, which is _ objective on which both sides agree, which is the — objective on which both sides agree, which is the restoration of the jc poa, _ which is the restoration of the jc poa, the — which is the restoration of the jc poa, the nuclear deal as it was. and then try— poa, the nuclear deal as it was. and then try to— poa, the nuclear deal as it was. and then try to move in parallel, so

there _ then try to move in parallel, so there needs to be synchronisation and coordination between the two sides _ and coordination between the two sides. that is the tax took their task— sides. that is the tax took their task that — sides. that is the tax took their task that these working groups that bethany— task that these working groups that bethany was talking about would have to deliver _ bethany was talking about would have to deliver on. and bethany was talking about would have to deliver on-— to deliver on. and am i being naive in thinking — to deliver on. and am i being naive in thinking that _ to deliver on. and am i being naive in thinking that both _ to deliver on. and am i being naive in thinking that both sides - to deliver on. and am i being naive in thinking that both sides are - in thinking that both sides are reasonably likely to do that, after all, joe biden is invested in this deal. he was in the obama administration and the iranian economy is under such pressure, sanctions relief would be very welcome in tehran. mac: sanctions relief would be very welcome in tehran.— sanctions relief would be very welcome in tehran. mac you are riuht. welcome in tehran. mac you are right- idoth _ welcome in tehran. mac you are right. both sides _ welcome in tehran. mac you are right. both sides at _ welcome in tehran. mac you are right. both sides at the - welcome in tehran. mac you are right. both sides at the end - welcome in tehran. mac you are right. both sides at the end of. welcome in tehran. mac you are i right. both sides at the end of the day want the same thing. and they have the political will to move _ and they have the political will to move in— and they have the political will to move in that direction. but there is a lot of— move in that direction. but there is a lot of political resistance and iran a lot of political resistance and iran and — a lot of political resistance and iran and washington and a lot of them _ iran and washington and a lot of them are — iran and washington and a lot of them are in disagreement in the region — them are in disagreement in the region so — them are in disagreement in the region. so there is never a guarantee that they would reach that destination, but at the end of the day, _ destination, but at the end of the day, the — destination, but at the end of the day, the alternatives to this agreement are even less palatable for both— agreement are even less palatable for both sides. either continue continuation sanctions for iran or the growth — continuation sanctions for iran or the growth of iran's growth of the nuclear— the growth of iran's growth of the nuclear programme and escalation in

thank_ more for more kind of arrangement. thank you _ more for more kind of arrangement. thank you very much forjoining us. its day seven in the trial of the former mini opera —— minneapolis police officer. derek chauvin — over the killing of george floyd, continues today. chauvin is accused of killing george floyd by kneeling on his neck in a case that triggered worldwide protests over racial injustice. in the last few hours we've heard from sergeant ker yang, a crisis intervention training officer at the minneapolis police department. both the defence and the prosecution questioned ker yang about the crisis training and refresher courses that officers receive. liutenantjohnny mercil, who is in charge of "use—of—force" training at the minneapolis police department, also testified. he told the jury that derek chauvin attended "defence tactics — use of force training" in twenty—eighteen, use of force training" in 2018, and that officers are taught about "proportion of force". we discussed proportionality regularly. and you said that you want

to use the least amount i of force as necessary? yes, sir. why is that? because if you can use the least amount, a lower level of force to meet your objectives, it's safer and better for everybody involved. the lieutenant was later asked about using force on a person who has stopped resisting. here's what was said. would be appropriate to restrain a subject— would be appropriate to restrain a subject with — would be appropriate to restrain a subject with a _ would be appropriate to restrain a subject with a knee _ would be appropriate to restrain a subject with a knee on _ would be appropriate to restrain a subject with a knee on the - would be appropriate to restrain a subject with a knee on the neck. would be appropriate to restrain a. subject with a knee on the neck and a knee _ subject with a knee on the neck and a knee on— subject with a knee on the neck and a knee on the — subject with a knee on the neck and a knee on the back— subject with a knee on the neck and a knee on the back for— subject with a knee on the neck and a knee on the back for an _ subject with a knee on the neck and a knee on the back for an extended| a knee on the back for an extended period _ a knee on the back for an extended period of— a knee on the back for an extended period of time _ a knee on the back for an extended period of time after— a knee on the back for an extended period of time after the _ a knee on the back for an extended period of time after the subject - a knee on the back for an extended| period of time after the subject had stopped _ period of time after the subject had stopped offering _ period of time after the subject had stopped offering any— period of time after the subject had stopped offering any resistance? i period of time after the subject had i stopped offering any resistance? no, sir. or has lost _ stopped offering any resistance? no, sir. or has lost their— stopped offering any resistance? no, sir. or has lost their pulse? - stopped offering any resistance? no, sir. or has lost their pulse? no, - sir. or has lost their pulse? no, sir. this comes afterjurors heard testimony from the minneapolis police chief, medaria arradondo on monday — who told the jury that the actions of derek chauvin, violated department policy. it's almost unheard for a police chief to testify against a former officer, and it was big news in the us media — making front page headlines on the minneapolis star tribune, as well as the the los angeles

times, the new york times, washington post and usa today. the list is a very long one. let's speak to our correspondent larry madowo — he's in minneapolis. he has been helping us throughout this trial. larry, we have seen a couple of clips there, but give us more detail on what we have heard today, please. we more detail on what we have heard today. please-— more detail on what we have heard today, please. we have heard from two senior officers _ today, please. we have heard from two senior officers from _ today, please. we have heard from two senior officers from the - two senior officers from the minneapolis police department speaking about the training the officers received and also focusing on use of reasonable force. when is it acceptable and when is it not? we heard from one officer, an officer with a phd in psychology who trains people at the minneapolis police department. then we heard from a lieutenant who specifically trains the minneapolis police department on use of force and defensive tactics. and he said, you need to use the minimum amount of force possible, and then the defence in its

cross—examination said is this a situation, though, that you took advantage of everything else happening around you? so in this case, they were trying to say that because there were agitated people around the scene when george floyd was arrested, the officers where impaired in theirjudgment and took longer to make a decision to render aid and put them in a side recovery position to breathe.— position to breathe. larry, i understand _ position to breathe. larry, i understand why _ position to breathe. larry, i understand why the - position to breathe. larry, i- understand why the prosecution position to breathe. larry, i— understand why the prosecution might want to hear from these witnesses because they are saying that chauvin acted outside of department policy. how did the defence go about questioning them? the defence is contesting that argument. they will bring their own witnesses to dispute that training. that's why whenever they cross—examine any of the witnesses from the police department, they have really fixated on what is a choke hold and what is a neck restraint. for instance, in the defence did get an admission from the lieutenant and the sergeant that, yes, they do train on some

necklace straight with up to a certain extent. it looks so far, because we have had about eight different members of the minneapolis police department testify, which is highly unusual. there is usually an america called what is —— what is called a thin blue line, officers protect other officers, that is why it is hard to protect and —— convicted officer. it looks like there throwing derek chauvin under there throwing derek chauvin under the bus, so what they're trained to do is distance themselves from their actions and say that this is not how we work. 50 actions and say that this is not how we work. , , ., ., we work. so help me understand that defence strategy _ we work. so help me understand that defence strategy a _ we work. so help me understand that defence strategy a little _ we work. so help me understand that defence strategy a little bit _ defence strategy a little bit further. is it to say that these actions were justified, further. is it to say that these actions werejustified, or further. is it to say that these actions were justified, or is further. is it to say that these actions werejustified, or is it further. is it to say that these actions were justified, or is it to say that actions didn't cause her to's death?— say that actions didn't cause her to's death?- -- _ say that actions didn't cause her to's death?- -- george - say that actions didn't cause her to's death? bath. —— george floyd's to's death? both. -- george floyd's that. the officers _ to's death? both. -- george floyd's that. the officers make _ to's death? both. -- george floyd's| that. the officers make split-second decisions, and _ that. the officers make split-second decisions, and in _ that. the officers make split-second decisions, and in this _ that. the officers make split-second decisions, and in this case, - that. the officers make split-second decisions, and in this case, they - decisions, and in this case, they were confronted with an agitated mob, sometimes we use that word from a mob. people were filming them, they were yelling and screaming at them, people calling them expletives, and that this was a suspect who was resisting arrest.

and that is why they had to handcuff him and put him in this position and restrain him, and also in cross—examination, eric nelson has gotten both officers to admit that sometimes you do restrain a suspect and when they come back, they become violent again, and you have to continue restraining them until you are certain and that they are not going to pose a threat.— are certain and that they are not going to pose a threat. larry, thank ou ve going to pose a threat. larry, thank you very much _ going to pose a threat. larry, thank you very much indeed. _ going to pose a threat. larry, thank you very much indeed. we - going to pose a threat. larry, thank you very much indeed. we will- going to pose a threat. larry, thank you very much indeed. we will be i you very much indeed. we will be back with the feed from the trial in a few minutes' time. the health of alexei navalny continues to be a focus. he's russia's most prominent opposition figure — he's in one of the countries most notorious prisons. and he's issued this statement on instagram saying several inmates had been diagnosed with tuberculosis. and that he is suffering from a severe cough and temperature of 38.1. navalny who's known for using dark humour — joked at the end of the post that if he's diagnosed with tb — it would perhaps "banish the back pain and numbness in his legs." that's is a reference to other symtoms he's been telling the authorities about — which he connects to his poisoning last year. according to german doctors, the nerve agent novichok was the cause.

a small group of doctors went to the penal colony today — demanding they be allowed in to see and treat navalny. this is his personal doctor — anastasia vasilyeva. she attempted to gain entry but was denied access. and was then escorted from the area after speaking to the media. really, really afraid for his health and his condition. i don't want to let his health reverse, and ijust... that's why i'm here now. do you trust the prison doctor? no! prison officials are denying the outbreak of tuberculosis — but they have confirmed navalny was taken to a prison medical unit — with symptoms of a respiratory disease. this report from the pro—kremlin izvestia says navalny was tested for coronavirus and is under the supervision of medical workers.

alexei navalny is in prison — after being arrested injanuary. he had been returning home to russia following treatment in germany for the poisoning. he was then sentenced for breaking parole conditions connected to a previous conviction — he broke the conditions because he went to germany after being poisoned. well mr navalny posted this photo on the 15th of march showing his freshly shaved head — and he described the prison as a concentration camp. now he is unwell while behind bars. he is also upholding a hunger strike. the bbc�*s sarah rainsford has more from outside the prison today. state television has recently been showing pictures from inside the prison here, showing mr navalny walking around, apparently uninjured. and they are using got to suggest that all these concerns about his health are very much exaggerated. but last week alexei navalny called a hunger strike, he said he would refuse food, all food, until a specialist doctor was allowed into him.

don't forget, this is a man who back in august was poisoned with a nerve agent. i think one thing that is clear, if the kremlin hoped that alexei navalny�*s imprisonment would take him out of the political picture here and silence and, well, clearly, he's very much still the focus of attention. now, let's turn to coronavirus and talk about vaccines. in the uk, organisers of a clinical trial using the oxford astrazeneca vaccine on children and teenagers decided they will not carry out any more vaccinations until they get more vaccinations until they get more information from regulators. bearin more information from regulators. bear in mind that they are still investigating whether there is a possible link between the vaccine and rare blood clots in adults. our health correspondent anna collinsonjoins us for more on this. iama i am a little confused. what is the difference between stopping giving more vaccines and spent —— suspending a trial? more vaccines and spent -- suspending a trial?-

more vaccines and spent -- suspending a trial? that's a very aood suspending a trial? that's a very good question- _ suspending a trial? that's a very good question. basically - suspending a trial? that's a very good question. basically what i suspending a trial? that's a very. good question. basically what the team from oxford university would say is that this is a brief pause, that only pausing immunisation, this isn't unofficial pause, and basically the reason they are doing it is because they are waiting to hear from the m it is because they are waiting to hearfrom the m hra, which is currently reviewing the astrazeneca vaccine to see if there is any potential link with a very rare type of blood clot in adults and the jab. so what they are doing is the team has announced that they are going to wait and see what comes out from those findings. but what they are really keen to stress is that this move, this very, as we say, not a pause, but this decision to halt immunisations for the short term —— short—term mayjust be for a few days. they are doing it not because of concerns of children or their safety, they are just doing it to be extra, extra cautious. there is no suggestion that there is any risk to the children that have been taking

part in the trial. i the children that have been taking part in the trial.— part in the trial. i am also confused _ part in the trial. i am also confused because - part in the trial. i am also confused because i - part in the trial. i am also - confused because i remember a part in the trial. i am also _ confused because i remember a couple of weeks back we talked about the fact that the european regulator had come out and said that this vaccine is safe to continue using. yes. come out and said that this vaccine is safe to continue using.— is safe to continue using. yes, and what the overriding _ is safe to continue using. yes, and what the overriding argument - is safe to continue using. yes, and | what the overriding argument would be is that it is safe to use from the prime minister borisjohnson to the prime minister borisjohnson to the world health organization, to the world health organization, to the vaccines minister, into the nhra mbe ma, the european regulator. they would all say that the vaccine is as safe as it can be. no vaccine is completely safe. there are always risks with this. at that for most cases, the risks definitely outweigh the benefits. the issue, you have to remember that coronavirus doesn't have many positives, but one of the positives it does have is that children are the least likely to be affected by it, the least likely to become severely ill, and the least likely to die. so when it comes to a vaccine, professor chris whitty has talked about this, when you are

having a vaccine on children, you wanted to be 100% safe because of that risk and effect. —— ratio. fine that risk and effect. -- ratio. one other thing _ that risk and effect. -- ratio. one other thing l _ that risk and effect. -- ratio. one other thing i find _ that risk and effect. —— ratio. one other thing i find myself wondering, other thing ifind myself wondering, if all these shifts in position on astrazeneca completely normal and we are just normal —— noticing them because there is particular attention on this vaccine, or is there something unusual going on with this particularjab was yellow i mean, there has been... any scientist who is covering and aware of what has been going on during the pandemic would say you know, this is just very different compared to any other time. you know, trials are rushed out, they are not peer—reviewed. everything is had to go at a great pace, and it is because of the pandemic, because we have never seen anything like this. astrazeneca has had a particularly tough time, and there are many questions why that may be. some people believe it is a political thing. but actually, what the team from oxford university would say is that they actually welcome any

scrutiny. the last thing they want is for any problems to go unchecked. thank you very much indeed. there is more information on that vaccine on the bbc news website. we switch from that story to israel, because they have been trying to form a new government, that's after last month's inconclusive election. the party won the largest share of the vote in so far it's been impossible for any group to secure the parliamentary majority he needs. bearin the parliamentary majority he needs. bear in mind, israel has held four elections in the last two years. our correspondent in israel explains the significance of the presidents invitation. this announcement gives the longest serving permits are in israel the first chance to try to form a new coalition government, but it's not going to be easy. the president himself making his televised announcement expressed doubt whether any candidates could get enough support when he was meeting the different political parties, only 52

out of 120 members of the parliament nominated mr netanyahu. that is some way short of a majority. now he is going to have 28 days to try to win more allies, and he can ask for a two—week extension, otherwise the president gets to choose somebody else or he can pass it back to the parliament. so a lot of political wrangling is going to be going on while mr annette yahoo's corruption trial continues. he denies any the president did say that his decision had been morally difficult, but he said that as the law stands, he can continue in his role as prime minister while facing criminal charges. living under coronavirus lockdown is a largely negative experience but one of the few positives that's emerged has been the chance to gaze on darker skies. one survey found light pollution fell by ten % last year in the uk — because fewer people are travelling — or doing much of anything else. and that's made it easier,

to look up and see the stars. our chief environment correspondent justin rowlatt reports. this is what a truly dark sky looks like. billions of stars wheel above the kielder observatory in northumberland. set deep in a forest, the observatory enjoys the darkest skies in england. and, throughout lockdown, senior astronomer dan monk has been filming the incredible views. people often do get emotional when they sit underneath this amazing dark sky and they realise how small they are in the universe. it can actually make people cry, at times. it's estimated 85% of us have never seen a truly dark sky. it means we are missing out because — it gives us a sense of our place in the universe, the awesome vastness of space.

but look at this. even a tiny light is enough to extinguish the stars and bring us right back down to earth. the reduction in light pollution this year is an exception. satellite images show the night sky has been getting steadily lighter across the world. changes in light have been linked with obesity, heart disease, depression and even cancer. you see, she's shaking? and some animals suffer even more profoundly. there are such a range of animals which are negatively impacted from this. when you think of our migrating birds, for instance, which are drawn off course by lights. insects, vast numbers of moths drawn to those lights, where they batter themselves to death or where they are predated by bats which change their behaviour to visit those lights, perhaps to their advantage, but to the deficit of other species of bats. so all of this is happening

out there in our night. so what can be done? the good news is we can tackle light pollution relatively easily. small measures like businesses making sure they are turning their lights off at night time when the buildings aren't in use. also, local government making sure that street lamps are properly shaded and the lights targeted, so it is not spilling out there and creating unnecessary light blight. that will mean more of us can see sights like this. justin rowlatt, bbc news, northumberland. us presidentjoe biden visits a vaccine centre at the virginia theological seminary. he will be announcing later on that all adults should be vaccine eligible by april the 19th. these pictures are just eligible by april the 19th. these pictures arejust coming eligible by april the 19th. these pictures are just coming in. eligible by april the 19th. these pictures arejust coming in. we know that already the us administered 150 million covid—19 shots, and now mr

biden is looking to escalate that timetable. i will see you in a couple of minutes. well, after a cold day comes a cold evening and a frosty night, but here's the good news. over the next two or three days, it is actually going to turn a little less cold — not mild by any means. in fact, the temperatures will remain below the average for the remainder of the week and into the weekend, but at least we're going to lose that biting arctic wind. you can see the wind here just from the motion of the clouds. you can see the satellite picture looping here, the clouds moving in roughly from the north, due south, so that's where our weather's been coming from — sleet, snow showers, rain showers in places, too, and that gusty wind. but this is what it looks like through this evening and overnight, largely clear across most of the uk, and the winds are dying down too. in fact, that current of cold air is slipping out into the north sea. —1 or —2 very early on wednesday

morning in the south. could be as low as “4 or —5 in the glens of scotland. so, wednesday is looking something like this — lots of sunshine around in the morning, sparkling and crisp, the winds will be lighter. you'll notice that. then in the afternoon, the weather changes. the winds shift, we will get this westerly breeze which is going to waft in some cloud, so it will end up being an overcast afternoon for some of us on wednesday. still chilly — 4, 5, 6 celsius. now, wednesday evening, we start to see a real change in the northwest here. in fact, the winds are coming off the atlantic — in fact, more out of the southwest — so that means that by early on thursday morning, we're generally frost—free. the weather has changed by then. no longer do we have the arctic winds from the north. and the reason for it is this weatherfront, which is sweeping to the north of us. you can see the wind arrows here blowing out of the southwest, so some outbreaks of rain and fairly cloudy weather across, broadly, the northwest of the uk on thursday. there's some sunshine and you'll definitely notice milder conditions in the south of the uk —

temperatures of around 11 degrees, for example, in birmingham and in london. now, this slightly milder weather will only be temporary, because once this weather front clears through, we open up the doors to another blast, a resurgence, of colder air from the arctic. so, yes, it temporarily turns a little bit milder through thursday and friday, and then come the weekend, it looks as though it's going to turn a bit colder again.

i'm ros atkins. welcome back to outside source. the us hasjoined indirect talks in vienna aimed at reviving the iranian nuclear deal — three years after donald trump abandoned it. president biden wants to return america to the deal, but tehran says it won't meet the us face—to—face until sanctions are dropped. translation: and if america's will come a seriousness _ translation: and if america's will come a seriousness and _ translation: and if america's will come a seriousness and honesty - translation: and if america's will come a seriousness and honesty is| come a seriousness and honesty is proven, it could be a better sign for a betterfuture, as sign of peace and security in the region and the world. also in the programme — its day 7 in the trial over the killing of george floyd, and another minneapolis police officer has given evidence that derek chauvin's actions went

beyond what was authorised. if you could use the least amount, a lower level of force to meet your objectives, it's safer and better for everybody involved. tensions are flaring up in eastern ukraine again — following reports of a russian build—up of troops along its border. moscow denies planning a military attack. and we'll hear from joe biden's son — hunter biden — who has spoken to the bbc about his drug use, grief and his very much scrutinised work in ukraine. well, let's talk aboutjoe biden's son, hunter biden, right now because he has spoken to the bbc. he was a target for donald trump in last year's presidential election — he was criticised for his drug and alcohol addictions and his lucrative appointment

to a ukrainian energy company. on that last point, hunter biden says he "missed" the perception that job would create. here he is speaking to the bbc�*s mishal husain. can you see why people look at the fact that the ukrainian gas company burisma took you onto their board for a reported $50,000 a month and think, "well, they were obviously doing that because of your surname"? when somebody comes to me with work, it's myjob to do the due diligence, which i did. what i missed, though, was the perception that i would create. what i missed in that period of time... and i know that it is hard to believe with 20/20 hindsight how i could possibly have missed that. at the point you were working for burisma, it was a lot of money to be paid for relatively few meetings a year... i mean, you were an alcoholic through all of that period. how much work for you

actually doing for them? member, and what i would also like you to remember is that yeah, well, i did the work that was required of every board member, and what i would also like you to remember is that i was paid the equivalent of what people are paid to serve on corporate boards. but i get it, mishal, i really do. i mean, i understand. but here's the bottom line. not one investigative body, not one legitimate journalist or group ofjournalists or newspaper have come to the conclusion other than this — my dad did nothing wrong and i did nothing illegal or wrong in doing so. but you're right. i created a perception, and a perception that was wielded against us in an incredibly wild and conspiratorial way. hunter biden is speaking now because he's releasing a memoir. and some on the right in america have used it

to re—establish those criticisms used in the election. the right—wing news website breitbart tweeted. .. we should say there's no evidence of corruption. the pro—trump, anti—muslim group act for america describes hunter biden as a "national security concern". and maureen callahan writes in the new york post... well, hunter biden spoke to mishal husain about his drug addiction, too, and his father's support at that time. he was there constantly. i mean, he literally showed up at my door. he reduced his secret service detail — this is when he was vice president — he knocked on my door... and i was living by myself for the first time in 46 years,

my brother had just died, i had separated with my wife, i was in an apartment by myself, and i was basically drinking myself to death. it was awful. i mean, grief does funny things. and combine that with addiction. it's a really hard thing to overcome. and he knocked on the door and he said, "hunter, are you ok?" i said, "i'm fine, dad." he said, "no, you're not. you need help." and i went, and i actually... he saved me then. but he saved me so many times. that's hunter biden talking to mishal husain. we're going to turn back to the conflict in the east of ukraine. we talked about it a lot in 2014 when war first broke out between russia—backed separatists and ukrainian troops. we're talking about it today because there are multiple reports of a russian military build—up.

ukraine says 28 russian battalion groups — involving 25,000 personnel — have appeared along its north and eastern borders in the last few days. reports suggest some russian artillery has come from as far as siberia. according to ukraine, russia has 3,000 officers and military instructors in areas of eastern ukraine that are marked here in red and which have been controlled by russia—backed separatists since they were seized in 2014. moscow very much denies it's helping the rebels and says any russians involved are volunteers. there is a lot of proof to suggest otherwise. now, since 2014, there have been multiple ceasefires which have broken down. the most recent was agreed injuly, but this is the situation now. there's still sporadic fighting along the line of separation which stretches for 500km. for example, this is avdiivka, which is this territory held by ukrainian troops. and this is the account of one ukrainian troop on the front line.

translation: every day, we have been heafina translation: every day, we have been hearin: that translation: every day, we have been hearing that armoured _ translation: every day, we have been hearing that armoured units _ translation: every day, we have been hearing that armoured units and - hearing that armoured units and takes driving. the tanks are not far away, one km tops. we can hear them warming up the tanks and in —— infantry fighting vehicles. russia hasn't denied troop movements, but it denies planning a military attack. here's a kremlin spokesman. translation: the main thing is to not provoke again - the military hostilities of the ukrainian armed forces in relation to their own people or people who live in the self—proclaimed republics. the situation in eastern ukraine remains very tense. any statements which can then be used to create the wrong picture can only further fuel tensions, i don't want to do it. not everyone shares russia's perspective on this, certainly not the west. last week the us put its forces

in europe on higher alert — citing "escalations of russian aggression". then on monday, the eu foreign policy chief raised "severe concern" over "the russian military activity surrounding ukraine". the uk added it too had "significant concerns". and here's former swedish prime minister carl bildt. obviously, they are getting all of these forces to ukraine for some set these forces to ukraine for some set the pressure on ukraine diplomatically or perhaps to undertake intermittent operation, hard strike, and then pave the way for some sort of diplomacy in order to pressure tf into further concessions on the issue, to get some movement from the russian point of view, in that direction of ukraine conflict, and is clearly a deliberate decision by the comment to ashley the conflict for sore this will lead us, we don't know, but it's dangerous —— by the kremlin to escalate the conflict. to be clear, russia does hold military exercises in the region. this analyst in the guardian points out that the current troop

deployment "appears out of cycle for such exercises, and are not regular troop rotations". and every time russia does that, it draws attention because of what happened back in 2014. this was vladimir putin in crimea, two months after russia annexed the region from ukraine. it was the biggest landgrab in europe since world war ii. and the escalation in the east of ukraine followed. vitaliy shevchenko from bbc monitoring joins me now. first of all, what is your reading of russia's motivation for moving all of these— it isa it is a frozen conflict that appears to be getting hotter, and we are seeing lots of social video posts of tanks and artillery and armoured vehicles being moved about right next to ukraine's border. russia says that it is free to do as it pleases, within its territory, if it wishes to send his trip somewhere, so be it, but ukrainians know that what can happen after you see

russian troops being moved about right next to a border. next thing you know, armoured men with no insignia storming your local government buildings. as for why now, what is going on, one trend of thought that we have picked up while watching russian media, the independent parts of the russian media, is that there is another big story unfolding in russia, involving a key opposition figure called alexei navalny, who is injail, hunger striking, apparently very ill, and that situation is of great concern to let putin and russia's under threat of more sanctions because of that, so the thinking goes, among some of the independent commentators in russia, this could be a distraction from the navalny situation which could potentially lead to more deaths. star;

and what has dominic is happening now poses serious questions for president to linsky in ukraine, for example —— what is happening. he has been saying nato is the answer. if ukraine joins the alliance, then what he calls russian aggression., but that, as far as the kremlin is concerned, that only is making things worse. president putin's spokesman said recently that if nato increases its support for ukraine, russia will have to respond forcefully. russia will have to respond forcefully-— russia will have to respond forcefull . . , 2 ., ., forcefully. vitaliy, there's another element to _ forcefully. vitaliy, there's another element to the _ forcefully. vitaliy, there's another element to the story _ forcefully. vitaliy, there's another element to the story that - forcefully. vitaliy, there's another element to the story that i - forcefully. vitaliy, there's another element to the story that i want i forcefully. vitaliy, there's another| element to the story that i want to ask you about, and this concerns information ukrainians are claiming is disinformation, but russia says it has launched a criminal case over the ukrainian military reportedly killing a child in a ukrainian attack in rebel held territory in don bass, again in the east of ukraine. what you know about these

have been social media post claiming the child has been killed by picking up the child has been killed by picking up some unexploded ordinance, so again that raises more questions about whether this can be a propaganda tactic, and after watching russian tv for the past couple days, i can take the pictures of that child are all over russian tv screens, so they are making the most of it. ., , tv screens, so they are making the most of it-— most of it. vitaliy, thank you very much. most of it. vitaliy, thank you very much- that _ most of it. vitaliy, thank you very much. that is _ most of it. vitaliy, thank you very much. that is vitaliy _ most of it. vitaliy, thank you very much. that is vitaliy from - most of it. vitaliy, thank you very much. that is vitaliy from bbc i much. that is vitaliy from bbc monitoring. let's turn back to our live coverage of the trial of derek chauvin in minneapolis. the court is hearing from a new witness, another police officer called nicole mckenzie. her role is a support court nader within the police force and she gives working offices medical training. before we go to the courtroom, just a warning that there may be graphic video or details in the evidence which you may find distressing. we're not in control

yes. all right, i have nothing thank you. —— nothing further. thank you. we are watching a live feed of the trial of derek chauvin, the former police officer accused of the murder of george floyd. the woman you can see on the left of your screen is an expert in medical assistance. she provides it herself but she also trains police officers in how to give medical assistance as well. the prosecution has been asking her a range of questions about the kind of training that she would give to police officers and we are

expecting, though you can never be sure until that happens, the defence attorney to take his turn to ask questions. there he is. getting up. he does not have to ask questions, of course, of every witness, has not chosen to on at least one occasion, but we will see full —— we will see. given the witness is still there, in time, his question will likely begin full to bear in mind, all of the witnesses we have seen so far, we are on day seven of the trial of derek chauvin, all of the trial of derek chauvin, all of the witnesses we have seen so far have been called by the prosecution. but his way the prosecution works. once the prosecution reaches the end of its list of witnesses, the defence will in turn be able to call its own witnesses too, if the defence is going to be asking questions, we are knock—on to hear them in this hour, sol questions, we are knock—on to hear them in this hour, so i will say thank you very much indeed for watching this addition of outside source and i will see you very soon

—— we are not going to hear them in this hour. bye—bye. well, after a cold day comes a cold evening and a frosty night, but here's the good news. over the next two or three days, it is actually going to turn a little less cold — not mild by any means. in fact, the temperatures will remain below the average for the remainder of the week and into the weekend, but at least we're going to lose that biting arctic wind. you can see the wind here just from the motion of the clouds. you can see the satellite picture looping here, the clouds moving in roughly from the north, due south, so that's where our weather's been coming from — sleet, snow showers, rain showers in places, too, and that gusty wind. but this is what it looks like through this evening and overnight, largely clear across most of the uk, and the winds are dying down too.

in fact, that current of cold air is slipping out into the north sea. —i or —2 very early on wednesday morning in the south. could be as low as —it or —5 in the glens of scotland. 50, wednesday is looking something like this — lots of sunshine around in the morning, sparkling and crisp, the winds will be lighter. you'll notice that. but then in the afternoon, the weather changes. the winds shift, we will get this westerly breeze which is going to waft in some cloud, so it will end up being an overcast afternoon for some of us on wednesday. still chilly — it, 5, 6 celsius. now, wednesday evening, we start to see a real change in the northwest here. in fact, the winds are coming off the atlantic — in fact, more out of the southwest — so that means that by early on thursday morning, we're generally frost—free. the weather has changed by then. no longer do we have the arctic winds from the north. and the reason for it is this weatherfront, which is sweeping to the north of us. you can see the wind arrows here blowing out of the southwest, so some outbreaks of rain and fairly cloudy weather across, broadly,

the northwest of the uk on thursday. there's some sunshine and you'll definitely notice milder conditions in the south of the uk — temperatures of around 11 degrees, for example, in birmingham and in london. now, this slightly milder weather will only be temporary, because once this weather front clears through, we open up the doors to another blast, a resurgence, of colder air from the arctic. so, yes, it temporarily turns a little bit milder through thursday and friday, and then come the weekend, it looks as though it's going to turn a bit colder again.

this is bbc news, i'm tim willcox. the headlines at 8pm. the oxford—astrazeneca coronavirus vaccine trial on children and teenagers is temporarily paused tonight — as the uk regulator investigates whether there is a possible link with rare blood clots in adults. oxford university say they won't carry out more jabs on younger people "out of an abundance of caution". more data is due to be published in the coming days — the world health organization says the vaccine's benefit largely outweighs the risk. forthe time being, there is no evidence that the benefit risk assessment for the vaccine needs to be changed. the argument continues over so—called covid passports — and what they might be needed for. the disappearance of 19 —year—old richard okorogheye — a body is about to be formally identified.
