on the other side, a labour councillor is arrested after an anti—racism march on suspicion of encouraging murder. meanwhile, more people, including john o'malley from southport, are now injailfor their part in the violence. there is very clear footage the developing disorder, and you were at the front of what was essentially a baying mob. we've tracked down some of the first people who shared the original misinformation online that helped fuelled the unrest. also tonight... here in the united states, donald trump has started his counterattack against the resurgent new democratic ticket of kamala harris and tim walz. at the olympics, team gb's ellie aldridge wins the first ever gold medal in kite sailing.

and the nobel prize—winning science that could cure blood disorders, available soon on the nhs. and stay with us here on bbc news for continuing coverage and analysis from our team of correspondents in the uk and around the world. hello. sir keir starmer says police forces should remain on high alert as they continue to deal with the aftermath of a wave of nationwide unrest. he's chaired a third cobra meeting with law enforcement officials, saying there's no doubt rapid sentencing as well as a major police presence across the country acted as a deterrent to prevent widespread violence last night. thousands of anti—racism protestors were on the streets, and apart from a few isolated

incidents, it was a calm evening. nearly 500 people have been arrested and more than 140 have been charged since the violence began last week, but police say those numbers are likely to go up significantly. daniel sandford has our top story on the strategy behind combating the threat of more violence. shouting. missile! they were the worst riots in more than a decade. this footage just released show is the intense pressure officers were under at the height of the riots in liverpool. withdraw! at times, they had to give ground... watch the flames! ..because the bombardment from fireworks was so fierce. bloody hell. had enough already.

in london, an early—morning knock today as police raided the homes of those suspected of being involved in rioting last week. the tactic is to arrest people as soon as they can be identified, and put them before the courts as quickly as possible. these are criminal thugs. any suggestion they're patriots or they've got a cause that they're protesting about is nonsense. they're criminals, and frankly, most of them are going to be charged with violent disorder, and most of them are going to go to prison for a few years. and following the shocking scenes in southport and liverpool last week, more heavy sentences were passed today. john o'malley, on the left, and 69—year—old william morgan were both jailed for two years and eight months. those who deliberately participate in such disorder, causing injury, damage and fear to communities, will inevitably be punished with sentences designed to deter others similar activity. the prime minister, who visited community leaders in solihull today,

was back in whitehall to chair another cobra emergency meeting tonight, and said he believed the tough sentences and police deployments were having an effect. and it looks like the deterrents might be starting to work. instead of violence by the far right last night, there were largely peaceful demonstrations by anti—racism campaigners. though this labour councillor, rickyjones, has been arrested by police on suspicion of encouraging murder. they are disgusting nazi fascists, and we need to cull their ranks. and get rid of them all. there's clearly huge relief in police and in government that there was no serious violence last night. but for now, everyone�*s holding their breath, hoping the violence doesn't begin again. the home secretary was at the main london police control room this morning, thanking officers for their work and looking at how they're using facial recognition

software to identify suspects. the police, the criminaljustice system, all has our strong support from across the government to keep going, to keep making sure that criminals pay the price for the kind of violent disorder, the thuggery, the extremism. everyone is hoping the worst of the rioting is over, but there are some far right actions planned for this weekend, and the prime minister told the police to remain on high alert. daniel sandford, bbc news. there were many across england braced for trouble last night. some businesses had closed early, others boarded up their premises. by and large the trouble didn't materialise. lucy manning has more from sheffield. the boards are coming down as the hope rises that the worst of the violence, the racism, the attacks on the police might be over.

in sheffield, the businesses that shut up shop yesterday are open. hundreds on this street last night protesting and protecting their community, including zurul�*s malaysian restaurant. it was a bit cheery to see that so many people came out last night, you know, to show what they stand for, to protect the premises and business here. i'm so grateful. i'd just like to thank everyone who came out last night. do you think people have the right to protest against immigration? yeah, we all have the rights to raise our voice, but it has to be in a peaceful manner and in a civilised manner. the protesters felt they had reclaimed the streets in sheffield and north and south from here. with the far right not even showing up, they hope that the tide is turning. but more anti—immigration demonstrations are set for the weekend. in newcastle, more than a thousand had gathered to make sure

there was no pavement for the far right to occupy. "geordies united" was the chant. seeing your community get smashed up on tiktok wasn'tjust... wasn't a feeling we could go through. we had to stand in the way and prevent something. newcastle really showed its true colours. and on that night, the fact that we turned up in such large numbers and we didn't have anything to face, just showed that the positive much outweighs the negative in this city. but the streets are still tense. the issues haven't disappeared, even if there is hope the heavy violence has. in barnsley today, the police almost outnumbered the protesters, both pro— and anti—immigration demonstrators. i have got indian family, and i've got mixed—race great nieces and nephews. i'm definitely not far right. however, we can house all these illegal immigrants for free, give them all these hand—outs, and that's my biggest grievance. what do you think of the violence that has been over the last week? disgusting, appalling. we were there on sunday,

and police were more brutal with us when we were being peaceful. we're getting classed, | all classed as far right. and we're not. we're just concerned citizens, and they're| going to carry on these protests. the police very much still on alert. lucy manning, bbc news. northern ireland's first minister, michelle o'neill, has condemned the continuing violence in belfast, and says there's no place for racism in our society. last night police officers came under attack in the east of the city. the stormont assembly has been recalled from summer recess to discuss the crisis. much of the unrest we've seen since the fatal stabbings of three children at a dance class in southport ten days ago was fuelled in part by misinformation spread on social media about the alleged killer. marianna spring has tracked down some of the people behind one of the first posts publishing false information, and asked them why they did it.

all this week we've been telling you a lot about how misinformation, false claims on social media, have been accused of fuelling riots in the uk. i've been investigating where it's coming from and why it's being shared. one of the first pages to share false information about the southport tragedy was this unregulated news site called channel3 now. they wrote a story about the stabbings in southport and quickly posted it on social media. some of the details were correct, but the name of the 17—year—old charged was false, and the article wrongly suggested that the alleged attacker was here seeking asylum. nevertheless, it was widely quoted and shared, often by accounts posting disinformation and far right ideas. and because the site name sounded like a news station, people might have been less likely to question it. now, because of what happened in the uk this week, i tracked down some of the people linked to channel3 now to find out who they are. james is an amateur hockey player from nova scotia in canada. and then there's farhan.

he's a dad who appears to be based in lahore in pakistan. when i reached out to farhan, he blocked me. but i've confirmed both of their identities by speaking to people who know them. we don't know if either of these people were responsible for the misinformation about southport, as the article doesn't have a byline. i was also able to speak to someone who says they're called kevin and based in texas. they say they're involved in the running of the site and its social media accounts. this person apologised for the inaccurate article, saying, "this shouldn't have happened, but it was an error, not intentional." what i found out about channel3 now points towards a site that wants to make money from jumping on stories quickly rather than intentionally looking to fuel riots. kevin said the site is covering as many stories as possible to generate income, so chasing clicks appears to have been more important than checking the facts. that's partly down to the design of the social media sites. x allows accounts to profit from their posts the more views they get, even if what they're

saying is false. so what's the solution? well, current legislation in the uk, like the online safety act, doesn't have the ability to deal with disinformation, although there are other laws that deal with hate, incitement, violence. plus lots of the people involved are based abroad. instead, the power lies mainly with the social media companies and partly with those who share this content, whether intentionally or not. x hasn't yet responded to the bbc�*s request for comment. marianna spring reporting there. many of those who've been arrested in connection to the disorder are teenagers. dominic casciani has been speaking to one mother who says her son was caught up in the unrest. when did you find out that your son had been involved? when the police raided me on monday and said that, "we're doing this raid". they said your son had been involved in violent disorder. in town. he's now facing court for going out. right. yeah. how do you feel about it? shocked, gobsmacked. hurt, angry. just didn't bring my kids up like that.

you know, i live in an area where there is a lot of violence and crime, but... i mean, it's pretty clear at the moment the courts are going to be making examples of people. that's right. is your son prepared for that? no, no, not at all. doesn't understand the bigger picture. and i think that's why he got caught up in the moment. he shouldn't have been... shouldn't have gone down, shouldn't have went out. if you could speak to the police and the judges about how they're dealing with the cases, what would you say? you know, what would you ask them to do in relation to your son? well, obviously, they're going to charge him for what he's done. but he's not a bad kid. you want him to be given the second chance, don't you? yeah. but a lot of people... a lot of people don't want anybody involved in the violence to be given a second chance. they just want them all jailed. everyone deserves a second chance. one mother whose son got caught up in the violence. daniel sandford is with me, along withjoe pike, our political correspondent. daniel, we heard that woman says her

son just daniel, we heard that woman says her sonjust got caught daniel, we heard that woman says her son just got caught up in the rioting, in the violence. and there is a sense perhaps that the government and the police have turned a corner on all of this. is that how they're seeing this? last niuht that how they're seeing this? last ni . ht was that how they're seeing this? last night was certainly a significant moment. it's the first time since tuesday last week that the police were braced for mass unrest and nothing of the sort happened, and certainly some senior officers are seeing that as a turning point. there are a number of factors at play. the first stiff sentences had just been passed. there were a large number of arrests. there were 6000 riot trained police officers on duty. police officers are wondering what the start of the football seasonis what the start of the football season is going to do. is that going to make a difference? but everyone is agreed from the top down, from the prime minister, from the home secretary, senior police officers, this is not the time to ease up. they want to see if there is mass violence at the weekend before they reassess. �* , .,

violence at the weekend before they reassess. ~ g ., ., , ., reassess. and joe, turning to you. this is the — reassess. and joe, turning to you. this is the first — reassess. and joe, turning to you. this is the first big _ reassess. and joe, turning to you. this is the first big test _ reassess. and joe, turning to you. this is the first big test for - reassess. and joe, turning to you. this is the first big test for keir. this is the first big test for keir starmer. he has only been in power a matter of weeks. how is he doing? i think luck has struck multiple times in keir_ think luck has struck multiple times in keir starmer's political career. certainly— in keir starmer's political career. certainly people around the prime minister_ certainly people around the prime minister do believe that he is lucky that his _ minister do believe that he is lucky that his first major crisis, his first— that his first major crisis, his first challenge, the first moment of tension _ first challenge, the first moment of tension in _ first challenge, the first moment of tension in his premiership is in a policy— tension in his premiership is in a policy area — tension in his premiership is in a policy area he knows well, because he was _ policy area he knows well, because he was england and wales's top prosecutor during the last significant rights in 2011, and there — significant rights in 2011, and there are _ significant rights in 2011, and there are clear lessons he learned there _ there are clear lessons he learned there that — there are clear lessons he learned there that he is trying to implement herei _ there that he is trying to implement here, and _ there that he is trying to implement here, and i'm told focusing on into night's _ here, and i'm told focusing on into night's cobra meeting. firstly on getting _ night's cobra meeting. firstly on getting the right public order officers — getting the right public order officers in the right places. they are still— officers in the right places. they are still on— officers in the right places. they are still on high alert tonight, we are still on high alert tonight, we are told — are still on high alert tonight, we are told. and secondly communicating the tough _ are told. and secondly communicating the tough sentences to ensure that behaviour— the tough sentences to ensure that behaviour does change. there is one thing _ behaviour does change. there is one thing that— behaviour does change. there is one thing that keir starmer and his team don't _ thing that keir starmer and his team don't want _ thing that keir starmer and his team don't want to talk about at the moment, _ don't want to talk about at the moment, and that is the underlying causes _ moment, and that is the underlying causes of— moment, and that is the underlying causes of all of this. that is may be understandable now, but i would argue _ be understandable now, but i would argue may— be understandable now, but i would argue may be not sustainable in the

so they are going to meet head—to—head? head—to—head ? yes, they are. head—to—head? yes, they are. they talked about dates and have agreed on at least one in september. this news conference by donald trump, there was quite a bit of scaremongering to start with. he said, world war iii is close and that the great depression could be close, america had become a banana republic without secure borders, unless there's a reason why he said he should be elected. there were some insults at kamala harris about her intelligence. he was also boastful. you expect all of that from him, but there are signs he has been honing his messages, because he has been forced to fight a different opponent to the one that he expected. he talked about policy, about the economy. he said that seniors wouldn't have to pay tax on social security benefits and that waiters

and others who rely on tips, which is quite a lot of people in this country, would have to pay tax on tips. he told people essentially that they would be richer under donald trump. because he is not fighting joe biden any more, a familiar opponent, trump is happy to recalibrate his messaging and, with three months to go until the elections, i think this was a sign that trump and the republican party are focusing down on a new challenge and your opponent, someone to take, i think, much more seriously than biden, who they were pretty confident they could beat. in bangladesh, the nobel peace laureate muhammad yunus has been sworn in as interim leader, saying his priority is to restore law and order in the country. bangladesh has seen weeks of turmoil, sparked by demonstrations demanding the end of civil service job quotas, the system that reserves posts

for specific disadvantaged groups which has been in place since independence in 1971. more than 400 people are thought to have died, after the protests became an anti—government movement. from the capital, dhaka, here's samira hussein. last week they were on the streets demanding the government step down. today they flocked to the airport to welcome the man they believe will lead them to a stable future, nobel laureate muhammad yunus. how do you feel? i feel good. i am back, there is a lot of work to be done. people are excited, they know that something, new opportunities have arrived. what is your message for people here? discipline. discipline, hard work and get it done. his positive message cannot disguise the fragile moment bangladesh finds itself in. weeks of deadly protest forced the country's autocratic prime minister to resign.

hundreds died in the unrest. several more were injured. and that same government wanted to imprison mr yunus. now he makes a triumphant return as interim leader. an incredible amount of security for mr yunus. the people here elated that he has finally arrived in bangladesh. they are putting their hopes for the country's future in his hands. we dream for a democratic country where no leader, no leader can be a dictator. we are the generation of z and we know that we can raise our voice, and we know how best to lead our country. a moment decades in the making. but for this woman, bangladesh's moment of hope has come at an unbearable cost. her 17—year—old son died in the protests. translation: i could not understand

why such a thing happened. _ i thought someone might have hit him in the head. i never believed that he would be shot. she finds some comfort in knowing her son would be happy. this change in government is what he wanted. tonight, a new era of government begins. mr yunus and his colleagues will hope the support of the people they enjoy for now endures. samira hussain, bbc news, dhaka. a second police officer has been placed under criminal investigation for assault, after an incident at manchester airport last month. video footage showing an officer kicking and stamping on the head of a man while he and his brother were being restrained led to protests in rochdale and manchester. more footage which emerged days later, showed the moments before the incident, when two officers were punched to the ground. the two brothers remain on police bail.

security officials in austria say a teenager under arrest has confessed to planning a suicide attack on a taylor swift concert in vienna. two other teenagers are also in custody, and ms swift has now cancelled all her three shows. fans that had already gathered in vienna ahead of the concert have been speaking about their mixed emotions to miss the show. we area we are a bit sad but we are glad to be alive. so, yeah positive.- be alive. so, yeah positive. yeah, after we came _ be alive. so, yeah positive. yeah, after we came last _ be alive. so, yeah positive. yeah, after we came last night, - be alive. so, yeah positive. yeah, after we came last night, we - be alive. so, yeah positive. yeah, after we came last night, we just| after we came last night, we just found _ after we came last night, we just found out, — after we came last night, we just found out, we couldn't be mad but we decided _ found out, we couldn't be mad but we decided to— found out, we couldn't be mad but we decided to be glad we decided to come _ decided to be glad we decided to come here anyway, because we put a lot of—

come here anyway, because we put a lot of effort _ come here anyway, because we put a lot of effort into it and we're just having _ lot of effort into it and we're just having fun — lot of effort into it and we're just having fun with all the others. dissappointed fans there — but taylor swift is due to play five dates in london next week, and the metropolitan police says there's nothing to indicate the concerts at wembley stadium will be targeted. gordon corera is with me. how serious was the threat in austria and what could that mean for her concert here next week? it austria and what could that mean for her concert here next week?- her concert here next week? it was a serious threat _ her concert here next week? it was a serious threat in _ her concert here next week? it was a serious threat in austria, _ her concert here next week? it was a serious threat in austria, it _ serious threat in austria, it appears, which was disrupted at the last minute. this 19—year—old had been radicalised on line and sworn allegiance to islamic state and our researchers reviewed weapons, explosives, knives, and the intent seems to be that he would turn up outside the concert and try and kill as many people as possible. one of his accomplices is alleged to have got a job working at the event management side at the concert venue. it was only disrupted a day orso venue. it was only disrupted a day or so because those concerts were due to start in vienna, apparently on a tip—off from american intelligence. originally, the austrian authorities said the threat had been dealt with in the concert

could go ahead but then taylor swift miss promoters cancelled concerts. that has raised questions about her trip to london next week for a series of high—profile concerts at wembley but the police here say there is no impact from what happened in austria for here in london. the mayor of london has said police will be working with the authorities and have learnt lessons from the past to make sure those concerts can go ahead at the olympics, team gb have won gold in a new event at the games, kite sailing. and katarina johnson—thompson has begun her heptathlon campaign. natalie pirks is live in paris with all the details. yes, gold in that women's kite surfing event was team gb bus first

goal since monday night and, along with bronze in the velodrome tonight, it means the team has 51 medals three days left of competition for the kite boarding is making its olympic debut at these for the games, and now great britain can boast its first ever olympic champion. commentator: and it is gold for ellie aldridge, _ and gold for great britain! in a discipline that sees competitors race above the sea at speeds of up to 45 mph, aldridge went into the final needing two wins to be crowned champion. and in marseille, she was flying. pipping the french favourite to sail away with a historic title and provide a timely boost to a disappointing regatta in what's traditionally been one of britain's strongest sports. so, could aldridge believe it? no! it's crazy. and there was more medal success in another sport where speed is of the essence. having been part of the sprint team that won gold on monday, emma finucane and katy marchant rached the final of the keirin. young welsh rider finucane was bidding to become the first british woman ever to win triple gold at a single olympics, but could only manage third place in a race won by new zealand's ellesse andrews. marchant finishing fourth.

so, emma finucane unable to add to her gold medal early in the week. she has to make do with bronze here. but nonetheless, that is a fifth medal now for team gb here in the velodrome this week. to get a bronze medal, it literally feels like gold to me, because i left everything out on that track, and if you told me a year ago i'd be coming to the olympics and getting a gold in the team sprint and then a bronze in the keirin, i would be like, no way. but here i am. in the beauty of the grand palais lies something more brutal. as tough as it gets forjadejones. the two—time taekwondo champion beaten in the first round for the second games running. her build—up had been overshadowed by controversy, only cleared to compete here last month after being found to have committed a no—fault doping violation on confidential medical grounds. today she insisted she is never taken performance enhancing drugs. jack laugher�*s olympics ended with a splash, only a big one. commentator: no, no, no, no! laugher finished seventh, but he's been a medallist at three successive games,

including this one, and has helped ensure that this is britain's best ever olympics in the diving pool. dan roan, bbc news, paris. well, here at the stade de france, we saw a dominant performance in the men's 200 metre final tonight, but it wasn't from the world champion, noah lyles. letseelay tebogo became the first man to win an olympic gold for botswana, with a standout run, in honour of his mother, who died two months ago. lyles, the 100 metre champion, had been bidding to do the double for the first time since usain bolt in 2016, but he could only manage bronze. after the race, it was confirmed that he has covid. and britain's double world champion, katarina johnson—thompson, has made an excellent start to her bid to win herfirst olympic heptathlon medal, at the fourth time of asking. a lifetime best in her weaker event, the shotput, plus her bestjump in five years in the high jump, has put an ecstaticjohnson—thompson into the overnight lead, 48 points ahead of the reigning champion, nafi thiam of belgium.

let's just take a look at the medal table. great britain are in fifth place with 13 golds, and 51 medals in total, so close behind hosts france byjust two medals tonight. in tokyo, at the end of day 13, they also had 51 medals but 15 of them were golds. there are eight golds up for grabs here at the athletics tomorrow night, including the men's and women's100 relays. thank you, natalie pirks in paris. an ingenious tool, which won its creators the nobel prize for chemistry, is to be used by the nhs as part of a new treatment for a genetic blood disorder. the therapy could be a cure for beta thalassaemia, and spare patients blood transfusions every few weeks. although it costs more than £1.5 million per person, nhs england has struck a deal with the manufacturer to cut costs. james gallagher has the full story.

kirthana balachandran is in hospital again, preparing for a blood transfusion. good morning. hi, how are you doing? i'm good, thank you. she was diagnosed with beta thalassaemia when she was just three months old. small sharp scratch. the condition causes pain, heart palpitations and cuts life short, so kirthana needs a blood transfusion every three weeks. it took me a very long time to accept that this is a condition for the rest of my life. have you worked out how much blood you have had in your lifetime? i've had about 13 transfusions each year. times that by 21 and then times that by two or three blood bags, probably about 500 blood bags or more. it's a lot of blood. yeah! how does this new therapy work? these discs are red blood cells, and it's theirjob to transport oxygen around the body. i can show you how, if we take a peek inside. they are full of haemoglobin, and this is what the oxygen actually sticks to.

but in beta thalassaemia the body can't make enough, so the blood can't do itsjob properly. so here is the big idea, doctors remove stem cells from the bone marrow. these are the cells that constantly make new blood. the dna is edited, and here is the really clever bit, it tells these cells to go back in time, to make foetal haemoglobin, the healthy haemoglobin we all make back in the womb. these reprogrammed cells are then put back into the patient, where they start making healthy red blood cells. the nhs says the therapy will be available within weeks. this is extremely exciting. to have such cutting—edge technology being made available in the nhs is truly ground—breaking. at the moment, it is available to about 460 patients with beta thalassaemia in the nhs. but of course, in the future, this will be applicable to many other patients with other conditions, and that is truly exciting.

for kirthana, it means a single infusion could replace a lifetime of treatment. i think it would change my life drastically, notjust mine, but many other lives with thalassaemia. to think i would never have to come for a transfusion again and have to work around, have to work my life around my transfusions, it would be crazy. james gallagher, bbc news. time for the weather. here's chris. this afternoon has been quite disappointing, with cloudy skies and outbreaks of rain working through, and it's
