the government over the 2013 protests. for the first time, black women artists from britain and the united states win awards at the prestigious venice biennale. of course it's an enormous accolade, but they also think why is it taking so long? it should have happened before now. welcome to our viewers on pbs in america and around the globe. elon musk, the world's richest man, has bought twitter in a deal worth $41; billion. in a joint statement, the two sides said they wanted elon musk said: he went on to say: and shortly before the announcement, elon musk tweeted: our north america correspondent david willis explains why elon musk was so keen to buy the company. the acquisition of twitter gives him considerable influence now. it also, potentially though, gives him a lot of headaches going forward. regulatory headaches. what sort of content moderation will be put in place? elon musk has made plain in the past that he is not a fan of content moderation. he says that twitter should be a centre for free speech. at that comes, of course, add some cost, as was seen with the rise of qanon and conspiracy theory groups such as that. the big question now, will donald trump, who was bad for life, of course, from twitter and other social media platforms following the insurrection at the us capitol building last year, be allowed to return. he had 90 million followers orjust to return. he had 90 million followers or just about when he was kicked off twitter and, of course, it would be very, very important to him if he does decide to launch another run for president to have that platform at his disposal. it would seem to be contradictory to the remark that he has made in the past, elon musk, for donald trump, the ban around donald trump, the ban around donald trump, the ban around donald trump to remain in place. but we willjust have to wait and see. david willis there. we can now speak to social media consultant matt navarra, hejoins us now from cardiff. thanks for making time for us. looking at the reaction on twitter, people projecting both their hopes and fears about what elon musk could do with twitter, based on what we know of him and what he has said of his intentions. you see what twitter needs right now? i think we can certainly twitter needs right now? i think we can certainly rely on the fact that he is going to spice things up on the platform. in one of the things the platform has struggled with his making money over the years and also growing its user base. and i think they given his track record interning businesses around and making successes of businesses there is some hope in that respect for the platform. interestingly, he has said he is not particularly interested as much in the economics of the deal and he is more interested in the freedom of speech aspect of it. i think we can expect nhfic and changes once this is all put into play. as to what those changes will be, is going to keep us guessing, i think. he has a vision so far around free speech. many would point to social media platforms that have tried to be quite lax around regulation to really promote the idea of free speech, but that doesn't always run up well against reality, does it? it run up well against reality, does it? ., , �* ., ~ ., does it? it doesn't. you know, we not does it? it doesn't. you know, we got lots — does it? it doesn't. you know, we got lots of _ does it? it doesn't. you know, we got lots of platforms - does it? it doesn't. you know, we got lots of platforms out i we got lots of platforms out there and in fact, truth social, which is donald trump as maycomb platform, which barely uses himself, it is one of those platforms that has tried to make a move that has so far failed miserably, tried to make a move that has so farfailed miserably, as have many that have come before it. we find with this platforms work readiness features a big selling point it actually isn't as appealing to a broad, larger audience as maybe these people think and also advertises a very keen to steer clear of toxic content. so it's good that he doesn't want to make maybe lots of money from this platform potentially, because maybe you won't without. he does want to move away from an advertising revenue model. it is a question as to how we will generate that income and subscriptions is one way he has put forward. subscriptions is one way he has put forward-— subscriptions is one way he has put forward. just on that money front, he put forward. just on that money front. he has— put forward. just on that money front, he has raised _ put forward. just on that money front, he has raised the - front, he has raised the financing for that in part through borrowing, that money will need to be paid back stop that's going to have some impact on his decisions on things like the advertising model, even though he does say this is not about economics. and this is it. what has become evident with this deal is there are lots of contradictions in that, one of them being, as you pointed out, the finance in it, elon musk is to finance this deal in terms of paying back the debt he has taken on and how he has kind of finances in general, but also he has said he wants to have freedom of speech and to reduce spam bots on the platform, he also wants to open up the algorithm, providing the algorithm for more people to see how it works, to give more tactical availability for those people who are creating spam bots in the first place. so there is a lot of contradiction in question marks and a lot of unpredictability, but that is what he likes and i think we will continue to see that. is will continue to see that. is that a hint into the sort of leadership we will see at twitter going forward then? is he not going to be as hands off, perhaps, asjeff bezos and washington post? is he going to be very involved, do you think, in deciding exactly how twitter works, going forward? certainly if ou works, going forward? certainly if you follow _ works, going forward? certainly if you follow what _ works, going forward? certainly if you follow what he _ works, going forward? certainly if you follow what he says - works, going forward? certainly if you follow what he says on i if you follow what he says on twitter but was he likes and dislikes about the platform and his strong views on it, you would expect him now, after providing us with this exciting, interesting development with twitter, he would want to be more hands—on with it, but given the number of companies is involved in it is difficult to see how we will be able to devoted a significant amount of time without upsetting people in his other companies, which also has shareholders demanding of his time as well. it will definitely be a change of management, he is not a fan of the twitter board as it stands. there will be lots of unintended consequences on this deal, it could potentially be a disaster for twitter, but it could also be the making of the platform. could also be the making of the latform. . , could also be the making of the latform. ., , ., platform. certainly an interesting _ platform. certainly an interesting one - platform. certainly an interesting one to - platform. certainly an i interesting one to watch. platform. certainly an - interesting one to watch. matt navarra, thank you forjoining us. matt is a social media consultant. the russian foreign minister, sergei lavrov, has again suggested there's a danger of the conflict with ukraine leading to a third world war, but he said he expected it to end with a peace agreement. mr lavrov said nato was in effect engaging in a proxy war with russia, and that weapons delivered to ukraine from the west would be, what he called, legitimate targets. five train stations were struck by russian missiles in western ukraine on monday. the railways have become a key target for russian forces, as they're crucial for both bringing in supplies and evacuating civilians. meanwhile, unrelenting russian attacks continue in the eastern donbas region. there's been fighting there since 2014, between ukrainian troops, and separatists, backed by moscow. russian artillery has been targeting towns and cities, where mainly civilians have been sheltering in basements, short of food and water. 0ur defence correspondent jonathan beale has travelled close to the frontlines. birdsong explosion the first sounds of spring, now drowned out by heavy shelling. in eastern ukraine, their battered flag still flying, but signs of life are vanishing fast, in the face of a renewed russian offensive. russia is making small gains, but creating widespread chaos and devastation, right across the region. most have already fled the towns and cities of the donbas. it's the few, like valentina, who've stayed behind. we found her trying to find food, during a lull in the fighting. translation: of course it's dangerous. _ everybody is scared. now we are even afraid of silence. you never know what will happen next. this is now her home. lysychansk has become an underground city. she shares a dark, dank shelter with another 50 people. they say they're running out of clean water and food, and some don't even care which side is winning. translation: my brain hurts. two idiots are fighting, two old men. all of them are guilty. all of them. distant bangs but there is no peace from the constant barrage of artillery. it's becoming yet another russian war of attrition. they're trying to break ukrainian forces along a front line that stretches for 300 miles. we have bomb attacks, rocket attacks every day. every day, every time, every day, every hours, all day. if we lose, lose not only ukraine, lose all world. and your countries, and other countries, too. here, they're still relying on mostly old soviet weaponry. they proudly show off their one british—supplied anti—tank missile, the nlaw. they've already used the other one to destroy a russian tank. we need that weapon - for our freedom, for a win, for that war. we need that weapon. and when we have more of that weapon, war is ending. - do you have enough of them? that position? yeah. this position? no. ukrainian forces have been holding the line here since 2014 against russian—backed separatists. they're still holding the line, but this time against the russian army. and what has been sporadic fighting over the last eight years has now turned into a full—blown war, and they are being pounded by russian artillery. this war is grinding down life in the donbas. deserted towns and cities, slowly being destroyed, as we travel through the region, from lysychansk to slovya nsk, to lyman in the north. the only certainty — this will be costly and brutal for whoever wins this war. jonathan beale, bbc news, eastern ukraine. in russia, there've been at least two huge explosions at an oil depot, around 150km from the border with ukraine. the cause is still being investigated, but it follows moscow's claims in recent weeks, that ukrainian attack helicopters, have been hitting targets on russian soil. there's been no official comment from either side about the explosions, which happened not far from the border in the town of bryansk. from there, our russia editor steve rosenberg sent us this report. caught on cctv, the prelude to an inferno. the russian fuel depot was engulfed in a fireball. flames lit up the night sky over bryansk. then, over to the right, you can see a second explosion. the border with ukraine is less than 100 miles from here. so, was this the result of a ukrainian strike to disrupt logistics for russia's military offensive? was it sabotage? neither moscow nor kyiv are saying. all day, plumes of thick, black smoke hung over the city, making bryansk feel like a war zone. "this never happened before," she says. "at 3am, we heard explosions. "we were amazed". "i don't know what this is," he says. "is it war here? "i suppose we're on the front line. "i wonder if ukraine did this". we've seen something similar, early this month, in belgorod. russia claimed that ukrainian helicopter gunships had opened fire. kyiv wouldn't confirm it. whatever the cause of today's fire, it's sparked concern in this city. when the kremlin launched its so—called special military operation two months ago, for many here, it was a case of "out of sight, out of mind". this was a conflict playing out on tv screens. but that's changing, and, for many russians now, hostilities are starting to feel much closer to home. back in moscow, president putin accused the west of prolonging hostilities in ukraine. translation: to our surprise, senior diplomats in europe - and the us are ordering their client state ukraine to do everything possible to achieve victory on the battlefield. this is impossible, so now they plan to destroy russia from within. vladimir putin claims he sent his troops into ukraine to bring russians security, but there's little sign of that. steve rosenberg, bbc news, bryansk. stay with us on bbc news. still to come: the winning black female artists at the centre of this year's venice art biennale. nothing, it seemed, was too big to withstand the force of the tornado. the extent of the devastation will lead to renewed calls for government help to build better housing. internationally, there have already been protests. sweden says it received no warning of the accident. indeed, the russians at first denied anything had gone wrong. only when radioactivity levels began to increase outside russia were they forced to admit the accident. for the mujahideen, the mood here is of great celebration. this is the end of a 12—year warfor them. they've taken the capital, which they've been fighting for for so long. it was seven o'clock in the morning on the day when power began to pass from the minority to the majority. when africa, after 300 years, reclaimed its last white colony. this is bbc news. the latest headlines: elon musk, has clinched a deal to buy twitter — in a joint statement, the two sides said they wanted to make the social media platform better than ever. the russian foreign minister, sergei lavrov, says nato is in effect engaging in a proxy war with russia, and that weapons delivered to ukraine from the west would be what he called legitimate targets. the businessman and philanthropist 0sman kavala has been sentenced to life in prison without parole in turkey after being found guilty of attempting to overthrow the government. the ruling was met with boos from a packed courtroom. human rights groups have condemned it as a travesty ofjustice. with me is our news reporter mark lobel. human rights activists have condemned this ruling. how significant is this verdict? critics of the ruling would say the main significance is what it says about the independence of the turkish judiciary. ever since the 2016 falco to depose president recep tayyip erdogan we have seen a purge, a rain drain and those that remain are paralysed by a climate of fear, those judges that remain. 0ne high court campaigner put it like this... high court campaigner put it like this. . .— like this... deeply shocking and a very _ like this... deeply shocking and a very defiant - like this... deeply shocking and a very defiant decision | and a very defiant decision which, _ and a very defiant decision which, of— and a very defiant decision which, of course, does not come from _ which, of course, does not come from this— which, of course, does not come from this court, it comes from the palace _ from this court, it comes from the palace and this has been a political— the palace and this has been a political trial from start to finish _ political trial from start to finish it_ political trial from start to finish. it is a shame trial, we call— finish. it is a shame trial, we call it— finish. it is a shame trial, we call it because there is no evidence. call it because there is no evidence-— evidence. ever since the government _ evidence. ever since the government was - evidence. ever since the government was rock i evidence. ever since the government was rock by anti—government protesters, they seem to blame civil society for a plot to unseat the government, saying they were agents of billionaire george soros. 0n were agents of billionaire george soros. on monday, seven defendants got 80 years each for trying to attempt to overthrow the government but the main charges have followed on the shoulders of one ringleader, 64—year—old philanthropist 0sman kavala. his life supporting minority rights and conservation but he also spent years in prison without a conviction and now faces the prospect of life without parole. he has denied all the charges against him. he said the majority verdict which came against him, which had tried to overthrow the government, was in eastwards, an act of assassination by use of the judiciary.— of the judiciary. what about internationally?

i mean, there are so many brilliant british female black artists out there. it should have happened before now. it's her time in the sun now. with a golden lion for the show, she's joined the likes of other famous british names, bridget riley and henry moore amongst them, to the very top biennale prize. boyce had this message. there's a longer arc of people that we need to keep saying, they're here. for more than a century, the world's most high profile art exhibition has centred around men. not this year. close to sonia boyce's pavilion, america's has a new temporary thatched roof, and an exhibition courtesy of simone leigh, the first black woman to represent the us here. they wanted to start this part of the show with this monumental artwork. simone leigh won the other golden lion prize for this 16 foot bronze sculpture at the central biennale show, curated by cecilia alemani. of the 213 artists featured in what's called the milk of dreams, between 80% and 90% are female. i wanted to give the stage and the platform to many amazing, wonderful artists who also happen to be women. and why has it taken so long, do you think? because we still live in a very sexist society, and it's very, very hard to advance. advance is happening in scotland's exhibition. this tapestry looks at slavery and the stories we're told. the artist, alberta whittle, is the first black woman to represent scotland in venice. i think the world's more ready to accept women artists, possibly. black women artists, i don't know. i'd like it if people weren't so scared to work with ideas of race or to kind of open up these conversations. but change is afoot here, certainly when it comes to whose art gets a place on the wall. katie razzall, bbc news, venice. ajapanese woman officially certified as the world's oldest person has died, aged 119. kane tanaka got married a century ago. she spent her later years in a care home. emily brown reports. kane ta na ka officially certified kane tanaka officially certified as the world?
