yevgeny prigozhin, is back in russia, nearly two weeks after wagner's failed uprising against the country's military leadership. a russian missile slammed into a residential building in western ukraine, far from the frontlines. and twitter is considering legal action against meta after its rival app threads launched just over 2a hours ago. i'm sumi somaskanda. the mystery over the whereabouts of yevgeny prigozhin, the leader of the wagner paramilitary group, took an unexpected turn today. prigozhin led the attempted mutiny against the russian defence ministry last month — it ended after the leader of belarus, alexander lukashenko, claimed he negotiated an end to the standoff with putin by granting prigozhin exile in his country. we know prigozhin�*s privatejet had landed in minsk shortly after the rebellion —

but we don't know whether he was on it. just over a week ago, lukashenko said prigozhin had arrived in belarus. on thursday, lukashenko said prigozhin is in russia. translation: as for prigozhin, he is in saint petersburg. - he may have gone to moscow this morning or somewhere else. he is not on the territory of belarus. lukashenko also said the question of whether the wagner units would relocate to belarus was still "in the balance", and would depend on the decisions taken by moscow and by wagner. he made those comments to a very small gathering ofjournalists, including the bbc�*s steve rosenberg. well, less than two weeks ago we were told that alexandr lukashenko had brokered a deal under which the mutiny would end and yevgeny prigozhin would move from russia to belarus and any wagner fighters who wanted to could join him in belarus. today, mr lukashenko

told us that, actually, yevgeny prigozhin is not in belarus, but he was in saint petersburg, he may be in moscow today and the wagnerfighters are not in belarus. he indicated they went back to their camps in russian occupied eastern ukraine. mr lukashenko said he also will be discussing the situation with wagner with vladimir putin in the near future, although the kremlin has not given any date for that discussion. so what is happening, what is actually going on? who knows. we also talked about nuclear weapons because the kremlin has said it is moving tactical nuclear weapons from russia to belarus and alexandr lukashenko said some have arrived and more would arrive by the end of the year. a short while ago he said that god forbid he should actually have to take the decision to use those weapons. i said to him, these are not your weapons to take the decision to use —

they are russian weapons. he said, well, if ukraine can fight with other peoples weapons, meaning nato weapons, then why can't i? the new york times is reporting that president biden is leaning towards sending ukraine "cluster munitions" — which can be used to drop small bombs across land that can indiscriminately hurt civilians. more than 100 countries signed a ban on them dating more than 15 years back, according to the un. the us is not party to this band. ukraine is facing dwindling resources as it continues its counter—offensive against russia. it is requesting more support from its allies. meanwhile russian missiles hit the western city of lviv, killing at least six people. ukraine's air force says the missile strike deliberately targeted civilians, despite russia claiming they only go after military targets. our gordon corera is in kyiv with the latest. the city of lviv is way out in the west of the country close to the polish border, a long way from the frontlines of this conflict, and so there was shock when an apartment building was hit in the early

hours of the morning. and you can see from the images that the devastation caused was extensive, with the roof torn off, the upper floor seriously damaged, people trapped underneath the rubble for hours. now, the russian military claimed it had carried out precision strikes against military targets, but the mayor of lviv said that this was the most significant attack against civilian infrastructure since the conflict began, since the full—scale invasion of february last year. president zelensky of ukraine promised a response, a "tangible response", he said, in an online message although he didn't specify exactly what that would be. this is just the latest attack which has killed civilians, three were killed by a drone strike in sumy earlier this week and last week 13 people were killed when a pizzeria restaurant in kramatorsk was hit by a missile and meanwhile the counteroffensive by ukrainian forces goes on,

slow going, trying to push through russian defences, probing them, looking for a place where perhaps a largerforce can be pushed through, but clearly there was a lot of shock today at that targeted strike which killed so many in lviv. we can speak now to ambassador bill taylor, former us ambassador to ukraine, and vice—president for europe and russia at the us institute for peace. good evening to you, thanks for joining us. how significant is it to see such a large strike on lviv, so farfrom the it to see such a large strike on lviv, so far from the front lines? . on lviv, so far from the front fines? ., , .h , fines? that is exactly the oint, fines? that is exactly the point. but _ fines? that is exactly the point, but there - fines? that is exactly the point, but there is - fines? that is exactly the point, but there is no - fines? that is exactly the - point, but there is no military rationale for these strikes. it is not close to the front line, there were no military targets, it targeted apparently civilian apartment buildings, infrastructure. so this isjust another war crime that the russians have committed against the ukrainians. d0 russians have committed against the ukrainians.— the ukrainians. do you think it tells us anything _ the ukrainians. do you think it tells us anything at _ the ukrainians. do you think it tells us anything at all - the ukrainians. do you think it tells us anything at all about l tells us anything at all about russia's strategy?—

russia's strategy? russia doesnt russia's strategy? russia doesn't have _ russia's strategy? russia doesn't have a _ russia's strategy? russia doesn't have a strategy. | doesn't have a strategy. russia, britain's strategy is to wait out the west, wait out ukraine —— putin's strategy. hope that somehow we will give up hope that somehow we will give up all the ukrainians will give up, people will get tired of supporting ukraine, and that is a failing batch, it's a failing bat. the united states is strong, europe is stronger but nato is strong, the ukrainians are strong. so putin is going to lose that bad, he doesn't have a strategy stop at the same time, ukrainian counteroffensive does appear to be moving slowly. find counteroffensive does appear to be moving slowly.— be moving slowly. and in an interview — be moving slowly. and in an interview with _ be moving slowly. and in an interview with cnn - be moving slowly. and in an | interview with cnn yesterday residents are lenski said he wanted to start the cou nteroffe nsive wanted to start the counteroffensive earlier and he had asked his allies, including the us for those weapons, that ammunition. do you think that might be an excuse for not making desired progress on the battlefield? hat making desired progress on the battlefield?— making desired progress on the battlefield? not making desired rouress battlefield? not making desired progress on _ battlefield? not making desired progress on the _ battlefield? not making desired progress on the battlefield - battlefield? not making desired progress on the battlefield is i progress on the battlefield is because it is tough going. there are minefields and then

more minefields and then more. and going through minefields is very very difficult, in particular if you are short of ammunition for your artillery. so president zelensky is right about the need for weapons and ammunition in order to accelerate that counteroffensive. your reporter is also right, what the ukrainians are doing it slowly, methodically but steadily probing and finding weaknesses on the russian line, and then the ukrainians have not committed their main forces. when they find the weakness they have their main forces ready to punch through. so that is what we will be looking for in terms of this counteroffensive. ~ ., counteroffensive. we mentioned the new york — counteroffensive. we mentioned the new york times _ counteroffensive. we mentioned the new york times is _ counteroffensive. we mentioned the new york times is reporting | the new york times is reporting tonight president biden is on the verge of giving cluster munitions to ukraine, these are bombs that rake apart into smaller explosive devices. they are very controversial as you know, many us allies have signed a treaty to ban them, should the usb giving these to ukraine? , ., ,

us treasury secretary janet yellen is in china for the latest in a series of visits intended to stabilise relations between washington and beijing. ms yellen was given a low—key welcome as she arrived in the chinese capital, as both countries have placed modest expectations on the visit. she is spending her first day in beijing in meetings with chinese premier li qiang, and liu he, a former economy tsar known to be a close confidant of china's president, xi jinping. as if to underline just how tense things are between china and the us, while ms yellen was still in the air on her way to beijing, mr xi was inspecting people's liberation army troops near the taiwan strait. he told them they must "dare to fight" and added: "it is necessary to deepen war and combat planning, "focus on military training for actual combat, "and accelerate the improvement in our capacity to win." earlier i spoke to bonie glaser of the german marshall fund about yellen�*s visit. thank you forjoining us. how significant do you think this

trip from janet yellen is coming just weeks after secretary of state antony blinken visited china? i secretary of state antony blinken visited china? i think it is an important _ blinken visited china? i think it is an important visit, - blinken visited china? i think it is an important visit, it - blinken visited china? i think it is an important visit, it is l it is an important visit, it is a process of starting to re—establish channels of communication between the us and china. in the run—up to what could a meeting between our two presidents, joe biden and xijinping at the our two presidents, joe biden and xi jinping at the apec leaders meeting in november. this is a very fragile relationship, there have been a lot of problems and friction, there has been suspension of some of the channels of communication for many months, and so this is a tenuous re— engagement. and so this is a tenuous re- engagement-— and so this is a tenuous re- engagement. presumably janet yellen will be _ engagement. presumably janet yellen will be looking _ engagement. presumably janet yellen will be looking to - engagement. presumably janet yellen will be looking to open l yellen will be looking to open up yellen will be looking to open up those lines of communication on economic issues, and also trying to convince the chinese that moves president biden and his administration had taken on export controls for example are not meant to instigate an economic war. do you think that will work?—

will work? the chinese are very soapicious _ will work? the chinese are very soapicious of — will work? the chinese are very suspicious of us _ will work? the chinese are very suspicious of us intentions, - suspicious of us intentions, they have claimed that there is really no difference between decoupling and de— risking. and i think secretary yellen will make an effort, just as our commerce secretary tried to explain this to her counterpart when he visited washington, dc about six weeks ago. we will see whether the chinese are convinced the us has talked about keeping small gardens with high fences, meaning there will be limited areas of technology that we don't want to send to china, because they could contribute to chinese military capability to threaten the united states and our allies. the question is whether it spills over into other areas of normal trade and investment. and secretary yellen has been clear that she thinks that would be a bad idea. that clear that she thinks that would be a bad idea. at the same time. _ would be a bad idea. at the same time, we _ would be a bad idea. at the same time, we saw - would be a bad idea. at the same time, we saw the - would be a bad idea. at the - same time, we saw the chinese earlier this week moved to export two key materials used in the manufacturing of

semiconductors, as you know, how do you thinkjanet yellen will address this? the chinese will address this? the chinese will absolutely _ will address this? the chinese will absolutely ask _ will address this? the chinese will absolutely ask this - will absolutely ask this question, of what the united states is planning to block and going into china, notjust areas of technology but this new executive order that is forthcoming, that could limit outbound investment from the united states into china and require screening of that investment. and i think that the chinese are trying to lay down some of their own, they have taken some action in restricting the sale by micron for example into china. but the new action you mention on imposing export restrictions on dally and germanium, they are trying to threaten the us and other countries to try and get us to limit the kind of restrictions we impose on china. but i think this may backfire. it may convince european countries in

particular but de— risking is necessary, that they have to exhilarated, because china is willing to use it access to raw materials as a political weapon. —— accelerate it. and thatis weapon. —— accelerate it. and that is too dangerous for countries to be continued to be dangerous —— dependent on china. dangerous -- dependent on china. ., ~' dangerous -- dependent on china. ., ~ , , china. you think this will be used as a — china. you think this will be used as a bargaining - china. you think this will be used as a bargaining chip i china. you think this will be used as a bargaining chip in| used as a bargaining chip in negotiations with janet yellen? i think the chinese are just trying to put something on the table and then yes, saying maybe vibe —— maybe both of us can step back and limit it is but i doubt that is going to work, because i think the united states is doubling down on our approach to china, that is making the united states and our allies more resilient and less vulnerable to chinese economic coercion, and limiting as i said china's military capability. as i said china's military capability-— as i said china's military caabili ., .., capability. janet yellen came out publicly _ capability. janet yellen came out publicly in _ capability. janet yellen came out publicly in favour- capability. janet yellen came out publicly in favour of - out publicly in favour of easing tensions with china in

an address you gave atjohns hopkins university in april and she added the following: do you think that's in line — that message is in line with the actual measures we've seen the actual measures we've seen the biden administration take? so far i believe it is in line with the measures the biden administration has taken. which go back to october 7 last year when the united states imposed some restrictions on the sale of semi conductors to china. so there's a lot of talk about applying it to other areas such as quantum computing and cloud computing, and artificial intelligence. it remains to be seen how far they should go. i want to highlight something that's interesting to me — the

united states and china are both putting security before economics. they are both really highlighting and prioritising their security interests. the chinese are doing the exact same thing. so this really should come as no surprise. we just have to reassure each other this isn't going to encompass normal trade. i think that's what we want to avoid. i think that's what secretary yellen will convey to her chinese counterparts. great to have your _ chinese counterparts. great to have your analysis. _ chinese counterparts. great to have your analysis. thank - chinese counterparts. great to have your analysis. thank you | have your analysis. thank you forjoining us. around the world and across the uk, this is bbc news. bbc news, bringing you different stories from across the uk. i ended up running a vineyard at the age of 20, kind of by chance. before me and my families moved here, i had no experience with farming or

viticulture. one of the most rewarding parts of the job, people smiling when they try my wine. all the blood, sweat and tears i've put into it, turning into this moment where people try a wine and they sort of think, "yeah, that's really nice." wine growing really has become all—consuming. i love it. it's an industry that doesn't have a lot of young people. they don't have a lot of young people, who like rock music and have a funny mullet. winning an award at wine ngb gold is fantastic to me. ifeel i deserve it. i don't mean it in an arrogant way. it's good for people to recognise the hard work you're putting in. you're live with bbc news. the world's largest gathering of humanoid robots is under way in geneva at the united nations ai for good global summit. our imogen foulkes is in geneva with a behind the scenes look at some of the latest

robotic technologies. there's no devices and gadgets you can shake a stick at here at the ai for good summit. for some people, this is clearly a bit of a marketing opportunity. but for the un's international telecommunications union, they say it's an opportunity for us to harness ai for the benefit of humanity. you can meet nadine here, a robot designed for social care. she's already been used in old people's homes in singapore. so could that be in singapore. so could that be in the future us? and do we even want it? one of the things the un is bringing governments as well as tech leaders here to geneva for, is to talk about what it calls guard rails. to harness. to put some regulations for how we use ai. it shouldn't be used to promote prejudice or bias against religion or race or politics or

gender. it should be used just, the un says, for us to benefit humanity. but will those big tech giants go for regulations around this new technology? that's a question that's probably going to be argued about for many years to come. twitter is considering legal action against meta over its rival app threads, which launched just over 2a hours ago. in a letter to meta's owner, mark zuckerberg, twitter�*s lawyers alleged his company had used trade secrets by hiring former twitter empolyees. for his part, twitter�*s owner elon musk said — "competition is fine, cheating is not". earlier i spoke to vivian schiller, former head of news at twitter, now execuitve director at the aspen institute. vivian, great to you have on the programme. i want to start with the fact that twitter is threatening to sue meta over threads. there's a letter sent saying the follow," twitter has serious concerns that meta

platforms has engaged in systematic, wilful, and unlawful misappropriation of twitter�*s trade secrets and other intellectual property." you worked at twitter, you have seen threads now, do you think there's something to this? first of all, i'm not a lawyer, let me be clear about it. it seems very odd, first of all, threads is only the latest in a long line of twitter clones, that includes blue sky, it includes mastodon and several others. i'm not exactly sure what it is about mark zuckerberg's project that's lit them up. the fact is, that twitter as a platform is not particularly complicated. one of its strengths is in its simplify. the complications is around content moderation and policy decisions and building audience. the platform itself is pretty straightforward. what's your supposition as to

why twitter is taking a look at threads and threatening a lawsuit? {iii threads and threatening a lawsuit? . lawsuit? of all the twitter clones that _ lawsuit? of all the twitter clones that have - lawsuit? of all the twitter| clones that have launched, lawsuit? of all the twitter - clones that have launched, this is probably the most viable in terms of being able to succeed. not because it's necessarily a better product than blue sky and others, but because it's built upon the back of the massive instagram list. so, as we can see, i mean, depending — i have seen various numbers, apparently ten million people have signed out to threads since yesterday, that doesn't mean necessarily it will be a long term success, but there's a built in audience.— a built in audience. take us behind the _ a built in audience. take us behind the scenes - a built in audience. take us behind the scenes at - a built in audience. take us. behind the scenes at twitter. how worried do you think elon musk really is?— musk really is? anyone who thinks they _ musk really is? anyone who thinks they can _ musk really is? anyone who thinks they can get - musk really is? anyone who thinks they can get into - musk really is? anyone who i thinks they can get into musk's headis thinks they can get into musk's head is kidding themselves. he's pretty erratic as a ceo, let's face it. i think he has — it appears he has an animus

towards mark zuckerberg, hence this whole thing about the cage match, maybe it's reciprocal. he's made a bunch of moves since he has taken ownership of twitter that really has destroyed a lot of value. especially, you know, including and especiallyjust in the last week when he limited the number of tweets that people could see unless they're signed on to be a paid blue check mark. that's sort of like the bbc saying we want to limit the number of programmes you can watch. it makes no sense. it defies both the mission and the business model of twitter. so, that and a number of very peculiar decisions he has made about the integrity of the site, you know, has really degraded twitter, unfortunately. so, i guess he's threatened. so one ofthe guess he's threatened. so one of the big _ guess he's threatened. so one of the big criticisms _ guess he's threatened. so one of the big criticisms is - guess he's threatened. so one of the big criticisms is that - of the big criticisms is that twitter under elon musk has eroded content moderation in the favour of what elon musk

saysis the favour of what elon musk says is free speech. do we know if meta will be different? we don't know- _ if meta will be different? - don't know. look, meta has its own problems in terms of — particularly around facebook, less so with instagram, but instagram has a different set of issues in terms of academic research that shows the negative psychological impact, particularly on young people, and particularly on young women. facebook itself is a known vector of information thatis known vector of information that is not reliable, misinformation, you know, disinformation campaigns. so, it's not like meta is the creator of these pristine sites. that said, there's a large audience of people who are pining — i include myself in this — pining for the pre—elon twitter. even though it was flawed, it was an incredibly useful and valuable product. incredibly useful and valuable roduct. ., . ., , ., , product. particularly for news and information. _ product. particularly for news and information. do - product. particularly for news and information. do you - product. particularly for news | and information. do you think in this space meta can be a real alternative? we in this space meta can be a real alternative?— real alternative? we don't know. that's _ real alternative? we don't know. that's the - real alternative? we don't know. that's the key. - real alternative? we don't i know. that's the key. again, the challenge is not building

something that looks like twitter. from an engineering point of view, that's not particularly difficult. the difficulty is, now with all these clones, and twitter still alive, i mean, i'm still on twitter — can threads gather enough critical mass of the kinds of people that were on twitter, which includes world leaders, which includes, you know, business titans and ceos, influencers, movie stars, rock stars, all kinds of famous people that made it sort of a very rich platform for a lot of things. but particularly as a place where news happens and then because so many journalists are on twitter, it then sort of becomes amplified through other platforms. can, you know, meta's attempt at the twitter clone called threads achieve that? really, really too early to say.— achieve that? really, really too early to say. vivian, quick last question, _ too early to say. vivian, quick last question, we _ too early to say. vivian, quick last question, we only - too early to say. vivian, quick last question, we only have . too early to say. vivian, quick| last question, we only have 30 seconds, how do you think beyond threatening this lawsuit we'll see twitter respond to threads�*s model? j

hello there. thursday was a better day for play at wimbledon and for the start of the test at headingley. there was quite a lot of cloud generally, but we did see temperatures peaking at 23 degrees. however, into friday, we're tapping into some heat and humidity, and temperatures may well peak as high as 29 celsius, 84 fahrenheit. there was some cloud and rain around, though, and you can see quite clearly where i'm talking about on the satellite picture. this is a frontal system bringing some wet weather, fairly showery first thing friday morning across scotland and northern ireland. slowly brightening up into the afternoon. but with that southerly wind direction dragging in that warm, humid air as we go through the day, producing clear skies across england and wales, temperatures will respond. highs of 29 celsius in one or two areas by the middle of the afternoon. so that means for the tennis at wimbledon, we could see temperatures as high as 27. it has the potential to be the best or the hottest day of this season's championship. and it'll be similar

story as well for the men's ashes. thunderstorms perhaps threatening as we go through the weekend. as we go into friday evening, it will be a relatively quiet one. during the early hours of saturday, we've got this front pushing in from the south—west, but temperatures not falling very far. it's going to be a humid night, an uncomfortable nght for getting a good night's sleep, particularly in the south—east, as temperatures only as low as 18—19 celsius. and with that front continuing to move in from the south—west, bumping into that humid air, that has the potential to spark off some sharp, thundery downpours. they will drift their way steadily north and east, so saturday will not be a wash—out by any means. but if you do have outdoor plans, it's worth bearing in mind that there could be some interruptions with some sharp showers. top temperatures as we go through saturday still on the warm side at 20—24 degrees, maybe 27 across parts of east anglia and the south—east. need to keep a close eye on sunday. there's a risk

of some really sharp, thundery downpours moving up from france, butjust where they will appear is still subject to question so keep abreast of the forecast for the second half of the weekend. just to summarise then, our weekend is going to start off on a humid note. there will be some decent sunny spells around from time to time, but also the risk of some sharp, thundery downpours.
