welcome to bbc news — i'm ben boulos, our top stories... president biden visits the city of tulsa on the centenary of one of the worst incidents of racial violence in american history. for much too long, the history of what took place here was told in silence. some injustices are so heinous, so horrific, so grievous they can't be buried, no matter how hard people try. aa a belarusian opposition activist tries to cut his own throat as a protest against his prosecution, we have a special report on the dissidents whose lives have been changed for ever. a special report from jordan, where we go back to meet

two syrian refugees — victims of the terrible conflict in their homeland. and the spetacular last pictures from a drone as it crashes into an erupting volcano. welcome to our viewers on pbs in america and around the globe. president biden has been visiting the city of tulsa in oklahoma to mark a century since a white mob attacked a black district, killing as many as 300 people. the attack on an affluent black community, known as black wall street, followed an alleged assault on a white teenage girl. president biden has called on all americans to reflect on what he described as the "deep roots of racial terror" in

the country's history. our correspondent gary o'donoghue reports from tulsa. this is the first time an american president has come to tulsa to acknowledge the horror of the massacre. local residents showed him around the greenwood cultural centre where he got to meet the only known survivors of that murderous night in 1921 — america's worst single act of racial violence in its history. some injustices are so heinous, so horrific, so grievous they can't be buried, no matter how hard people try. in the light of the tulsa massacre and a year where racial injustice has been foremost following the murder of george floyd, the president did set out his ambition to redirect federal funding to assist minorities�* small businesses. i'm determined to use every taxpayers�* dollar that's assigned to me to spend going to american companies and american workers to build

american products and, as part of that, i'm going to increase the share of the dollars the federal government spends to small disadvantaged businesses, including black and brown small businesses. there was little such help for greenwood after 1921. in fact, the city purposely passed rules and regulations that would make it harder for black businesses to rebuild. it took decades for greenwood to recover, although it never regained its former glory. but now local entrepreneurs do want to recapture that past and they are looking to local, state and federal government to help. the black wall street liquid lounge is one place trying to revitalise the area. but while there is optimism for its future, the owner still believes the city is divided. i'm more of a bootstrap kind of guy. so i think that the movement starts here with the citizens and the small business

owners working together. if some are thinking about greenwood's future, others are praying for answers about its past. archaeologists now believe that dozens, if not hundreds, of victims of the massacre were buried in mass graves, and the work to find them begins in earnest today. i feel a sense of pride, because right now we are opening up the ground where there is hidden history, a dark history. this is a murder investigation right here. a murder investigation. the work excavating the graves will take months, if not years. proof, if needed, that the past is rarely over. gary o'donoghue, bbc news, tulsa. well, earlier i spoke to dr rashawn ray who's a fellow at the brookings institution and a regular commentator on matters of historical importance to the african american story in the united states. i asked him about the lasting impact the tulsa massacre has on american society today.

it is monumental and it's monumental for a couple of reasons. see black wall street, tulsa, greenwood, what it represented was 35 blocks of black excellence, of people who had pulled themselves up from the bootstraps. there were dentists, there were other small businesses, there were movie theatres, there were homes that were all burned to the ground, where not only people lost their lives, but people also lost wealth and the ability to accumulate generational wealth. so black wall street is what society, what the united states had told black people that they should do. and it's monumental today, of course, being 100 years, but also the fact that president biden went there as one of the first sitting presidents to do so is monumental. and i think that the pathway that he's laid out in terms of legislation can help to amend the wrongs here. just to explain that

pathway for us and why it matters so much. yes. part of what people have to recognise is that after black wall street was decimated, that it was not only that particular city, but there are several around the united states that were similar to greenwood that were also decimated in similar ways by the kkk, white supremacists and at times where law enforcement and the federal government were playing a complicit role in these acts. now, part of what biden is trying to address is not just those massacres, but also the legacy of them, jim crow, which is housing segregation, and then also business ownership, which has oftentimes prevented black businesses from being able to gain the financial backing and to grow to help black communities. biden is aiming to address both of those gaps when it comes to the racial wealth gap in terms of entrepreneurship and homeownership.

for many years, the anniversary of what happened went unmarked. it was almost like it had been hidden, almost extracted from the history books. how important is it that it is now being marked and in particular to the descendants of the people who were affected by that mob attack? well, look, it is vitally important. we know that there are few people who were literally there on that day 100 years ago who have been hoping for this particular moment. as the pressure builds on dissidents to president lukashenkuh�*s regime's in belarus, an activist stabbed himself in the neck during a court appearance in the capital, minsk. footage appears to show stepan latypov collapsing after using what looked like a pen as a weapon on tuesday. mr latypov was taken to hospital and was reportedly ok after surgery. he is accused of setting up opposition social media and resisting police during his arrest last september. he has denied all the charges. mark lobel reports.

lying unconscious in a minsk courtroom. activist stsiapan latypau moments after reportedly stabbing himself in the neck after addressing the court. translation: he got up and said, police officers l told me i would be put in the confinement cell. my relatives and neighbours would be prosecuted under criminal law if i do not confess. then he took something white and started literally to cut his throat, everyone started screaming. police officers could not open the defendant's cage for a while. eventually he was rushed to hospital. as the pressure on political prisoners grows, the prominent opposition leader svetlana tikhonovskaya met austria's leader. he pledged more action if things don't improve. translation: we should be open for further -

sanctions if necessary. i think it's important that the sanctions should be as precisely targeted as possible, to target the regime and not the civil society, not the people. meanwhile, belarus's ally russia says it is planning to conduct 4,000 military training exercises, like these ones in 2017, over the summer. translation: the main efforts will be directed at improving - individual performance and maintaining the intensity of combat training. the main outcome of the academic year will be the joint russian—belarusian strategic exercises, zapad 2021. meanwhile, back in belarus, its health ministry said stsiapan�*s condition is stable and non—life—threatening. but president lukashenko has now added a travel ban for most citizens following his harsh crackdown on opposition activists since his heavily

contested election victory last august. as he seeks to strengthen his grip on his disputed rule, intent on providing little escape for those unwilling to accept it. mark lobel, bbc news. later, we'll have a special report from minsk looking at how the lives of some people have been changed for good by the protests in belarus. the african union has said it is suspending mali's membership of the organisation in response to last week's military coup. members of the group had already threatened sanctions if a civilian—led government was not restored. the decision comes two days after the economic community of west african states, known as ecowas, also halted mali's membership of its group, demanding the country stick to a timetable to restore democracy. one of the most senseless consequences of war is its impact on children, and in syria, the lives

and futures of a whole generation have been badly hit. it's now more than ten years since syria descended into civil war. our world affairs correspondent caroline hawley reports from jordan, where she's been back to meet again the children who've already paid a very heavy price. mustapha and his little sister, douaa, survived a bombing raid by the syrian regime seven years ago. both their parents were killed in the explosion that nearly took his life too. mustapha broke both his hips and still has shrapnel in his brain which doctors have told him they can't remove. we first met mustapha when he was five. over the years, the one thing that has never changed is his irrepressible smile. right now, mustapha has good reason to be happy.

he and douaa and their grandmother are about to be given a new home on the other side of the world. it's time for a last play with his cousins before he goes. as always, he does his best to keep up but his injuries seem to affect him more than when we saw him last. his grandmother has looked after him for the past few years as if she was his own mum. she is frail now and can barely walk. for her, it won't be an easy move. but in the final hours before their departure when the children are too excited to get to sleep, there is a last—minute hitch.

so they should actually be in the air right now but when you are a refugee you don't have much control over events and there has been some kind of delay. the bureaucratic bungle means it will be weeks at least before he can fly. rahaf and mustapha don't know each other but they would recognise each other�*s pain. when she was three, her home in syria was hit by government shelling, setting her bedclothes on fire. her sister amma's burns were more severe. in 2012, we filmed amma having surgery on herface.

she had so many operations over the years, so many medical procedures, herfamily have literally lost count. rahaf herself has had 12, one for every year of her life, but nothing she has been through can match the agony of losing her sister, who was also her best friend. this was the last photo taken of amma before she got ill last year with an infection her body couldn't fight. rahaf is getting ready to visit her sister's grave.

when i first met them, neither girl would look at themselves in the mirror, but both had grown hugely in self—confidence before amma died. a casualty of serious conflict years after the rocket fell. so much surgery on amma's injuries had taken a massive toll. her family took her from doctor to doctor to try to save her and after all that she had been through and survived, theyjust can't believe that now she is gone. the long reach of syria's war. for mustapha, there is still a new life in australia to look forward to, but that small piece of shrapnel buried in his brain that causes him so much trouble will be with him wherever he goes. stay with us on bbc news, still to come: what happend to a drone trying to film an errupting, icelandic volcano.

the queen and her husband began their royal progress to westminster. the moment of crowning, in accordance with the order of service, via a signal given with the great guns of the tower. tributes have been paid around the world to muhammad ali who has died at the age of 7a. outspoken but rarely out—fought, ali transcended the sport of boxing of which he was three times world champion. he was a good fighter, he fought all the way to the end — even through his illness. yes, he did. uefa imposes an indefinite ban on english clubs playing in europe. today is the 20th anniversary of the release of the beatles lp sgt peppers lonely hearts

club band, a record described as the album of the century. this is bbc news, our top story: president biden visits the city of tulsa on the centenary of one of the worst incidents of racial violence in american history. when the president of belarus — alexander lukashenko — ordered a ryanairflight to divert to minsk, and arrested a dissident who was on board, opposition activists still inside the country were shocked and scared. the mass protests that began last summer have been crushed, with fear driving people off the streets. the bbc�*s sarah rainsford and matthew goddard have just returned from minsk, where they met some of those whose lives have been changed for good by the protests.

in belarus, they tried to topple a president. the response has been brutal. it's a very dangerous occupation in this dangerous time. now, president lukashenko has diverted a plane to catch a critic. the west is punishing him with sanctions, but russia has his back. and yet the demand for change has gone nowhere. on the streets of minsk, life looks calm now, orderly. but last summer, a presidential election ignited a political crisis in belarus that's still smoldering. i went to meet one of many here whose lives have been transformed. lvon ran a bar, but he was an opposition activist, too. and last august, he was arrested. he didn't see miki for six months.

last year, vast crowds came out demanding change in belarus — an end to a quarter of a century of one man's iron rule. alexander lukashenko teetered but never fell. levon�*s time with his son is limited. he still has to serve a year

of correctional labour somewhere farfrom home. many have already fled. those who remain are mostly keeping their heads down. belarus has seen cycles of protest and repression before, but not on this scale. there are hundreds of people behind bars. i've never known belarus like this, not in all the years i've been coming here. people now are just terrified to speak out because with the crackdown, with all the arrests, you never know who they'll be coming for next. now they're coming for the journalists. vassil was nervous about meeting, but his wife, a prominent news editor, has just been arrested.

he was waiting to hear whether marina had been charged. so is there any news, anything new? there are no news. no news? no news. of course, i hope. but the hope is a little one. tut.by has now been closed down, the website blocked, and marina and half her team are in custody, accused of tax fraud. marina was ready. it's a very dangerous occupation in this dangerous time. but vasil believes belarus has reached a turning point. the people were tired. and theyjust wanted to... to have a chance to change. there's no way back from that? yeah. we cannot express our position.

we cannot demonstrate. but nobody has changed his mind. during the protests, there were red and white banners and bits of cloth draped from monuments and hanging from balconies all over this city. these days, there's not a trace of that stuff left any more. and today, people are even getting arrested for wearing red and white socks. olga's husband has already spent a year behind bars. all that time, these letters were their only contact. when we met, the couple had just seen each other in court. pavel got seven years for organising mass protests.

so the protesters have been squeezed off the streets — their challenge crushed. alexander lukashenko even forced a plane down to catch a dissident. as the west cuts ties, russia is now a criticalfriend.

a huge fire on board a cargo ship off the coast of sri lanka has finally been extinguished after almost two weeks. the ship, laden with toxic chemicals, caught fire as it waited to enter colombo port, spilling debris into the ocean and coating pristine beaches. experts say it's one of the worst ecological disasters to hit sri lanka. a drone trying to film a volcano in iceland has crashed into a lava spew. youtuberjoey helms wanted a mesmerizing close up view of the spectacle, but the flight didn't go quite to plan.

what an expensive last flight! a reminder of our top story: joe biden has become the first sitting us president to visit the city of tulsa in oklahoma, where a century ago hundreds of black americans were massacred by a white mob. mr biden met the handful of surviving members of the affluent greenwood neighborhood where the killings took place. that's it. you can reach me on twitter — i'm @benmboulos. you're watching bbc news.

thank you for watching. hello again. tuesday was the hottest day of the year so far. a title that will last until, well, later today when temperatures are expected to get a little higher still. most of us had skies like this, then, plenty of sunshine around and it was warm widely. 26.1 celsius was the highest temperature — that was in cardiff where we have the heat as far north as northern scotland at kinloss at 25 celsius. here, just 11 celsius. here we had low clouds and fog. there is another batch waiting to move across the north sea over the next few hours. meanwhile, over in france, we have some thunderstorms beginning to spread their way northwards. now, those thunderstorms coming from a cloud called altocumulus castellanus. you quite often don't get much rain from it, what falls can be big blobs, but you can get pretty dazzling lightning displays and lots of thunder.

you might see some of that in the channel islands in the next few hours, before those downpours spread into southwest england, where we could get some heavier rain mixed in. now, as that kind of air comes up from france, it'll start to feel much more humid across southern areas. eastern coastal areas of both england and scotland starting the day sunny, but late morning, i think we probably will see some areas of low clouds and fog move back in, particularly from about north yorkshire northwards, so it will be a lot cooler for these areas. temperatures, 27 celsius, wouldn't be surprised if we saw 28, just depends how much sunshine we get. on into thursday's forecast, well, the low pressure bringing the showers is still with us. this cold front�*s important — to the east of that, we could see some showers break out just about anywhere. now, there certainly will be some showers going across northern england and into scotland. but across england, well, this is where the cold front is, so we could get storms breaking out just about any time as we go through thursday, some of them could be really heavy as well. temperatures, still pretty high, 211—25 celsius

across eastern areas of england, but otherwise, those temperatures coming back down closer to average. now, thursday night, even into friday, we could still see some storms affecting parts of eastern england, but eventually, the whole of the uk will get into that fresher air that's come off the atlantic. so temperatures will be coming back closer to average. still, though, with some spells of sunshine around, it's not going to feel cold at all. it's going to be pleasant in the sunshine. temperatures about 19 in cardiff, 23 in london, 18 in glasgow. that's your weather.
