hello from the bbc sport centre. the debate over the criteria for participation in women's sport continues after italian boxer angela carini abandoned her olympic match against algeria's imane khelif inside 46 seconds. khelif is one of two boxers, along with taiwan's lin yu—ting, who fights later on friday, who have been cleared to compete in the women's boxing in paris, despite being disqualified from last year's women's world championships for failing to meet gender eligibility criteria. nicola adams, the first british female boxer to win gold at an olympics, said on social media: "that it was hard to watch another female fighter be forced to give up on her olympic dreams." here's the ioc spokesperson

mark adams, speaking on friday: this is a minefield and, unfortunately, as with all minefields, we want a simple explanation. everyone wants a black and white explanation of how we can determine this. that explanation does not exist. neither in the scientific community nor anywhere else. as i've said before, if we can find a consensus and we will work towards a consensus, we will certainly work to apply that. clearly that's not going to happen at these games, but this is a question also, i guess, in all sports and i think we are open to listen to anyone with a solution to that question. simone biles won the all—around gymnastics title for her second olympic gold at these games on thursday, cementing her place back at the top of her sport with another impressive display. biles finished with an overall score of 59.131, ahead of brazil's rebeca andrade and her us team—mate sunisa lee to win the all—around gymnastics

title, just as she did in rio in 2016. it's biles�* second olympic gold in paris, sixth gold overall and ninth medal in total. she's the oldest winner of the event for 72 years. for me personally, tonight it means the world to me and it is, i don't want to compete with rebecca no more, and tired, she is way too close. i've never had an athlete that close would definitely put me on my toes. all in all i'm super proud of my performance tonight and the fight i have had in the last two or three years competing mentally and physically. the olympic games is and physically. the olympic games is an amazing experience or i couldn't be prouder. andy murray's playing career has come to an end in paris after the former world number one and three time grand slam champion was beaten in the quarterfinals of the men's doubles. he and dan evans were beaten in straight sets by america's taylor fritz

and tommy paul 6—2 6—4. murray, who is 37 and has had more injury problems this year, confirmed before the games that it would be his final event, so this result brings the curtain down on an extraordinary career which included two wimbledon titles, the us open and of course two olympic gold medals. to friday's action, and the athletics is under way at the stade de france, where team gb�*sjosh kerr cruised through to the 1,500 metre semifinals, alongside rival jakob ingebrigtsen, while the women's 100 metres heats have also been taking places. gb�*s daryll neita and dina asher—smith among those through to the semifinals so far, neita running a season's best of 10.92 seconds, alongside the american sha'carri richardson, one of the favourite to win the 100 metre title in paris. team gb have won three medals on friday. two came in the rowing, where emily craig and imogen grant have just won gold in the lightweight women's double sculls. earlier, tom george and ollie wynne—griffith won silver in the men's pairfinal.

the gb pair had led for most of the way, but croatia's valent and martin sin—kovic produced a brilliant late sprint to snatch the gold, with switzerland taking the bronze. the third came in the diving. the team gb pair of anthony harding and jack laugher earning bronze in the men's synchro three metre springboard final. the gold was won by the chinese pairing of long daoyi and wang zong—yuan, continuing china's domination of the sport at these games. they have taken all four gold medals available so far. the mexican pair ofjuan celaya and osmar olvera got second with theirfinal dive. manchester united manager erik ten hag believes the foundations are in place for success at old trafford, following a restructure off the pitch during preseason. since the arrival of new owners ineos and sirjim ratcliffe there have been significant changes to the clubs�* boardroom and coaching staff, something ten hag feels can

help manchester united progress. we knew we had to change when we started the project and it's good. the new structure, the new leadership is coming in. players... new players coming in. we improve the dressing room, but of course, the structures are still there. the club has made changes and can look forward with people with great abilities and i am sure that this will give us an even better foundation and that we can attack. and finally, tributes have been paid to the former leicester city football manager craig shakespeare, who died at the age of 60 on thursday. england and manchester city midfielder jack grealish, who worked with shakespeare at aston villa, said: "one of the greatest people i've ever met not only in football but in life. everyone really will miss you, shakey. absolutely devastated, sending all my love to his family." and that's all the sport for now.

let's return to that breaking news on the violence that followed the killings in southport. seven men have been charged with violent disorder after a riot broke out in hartlepool linked to monday's mass stabbings. one of the men has also been charged with assaulting an emergency worker. sir keir starmer has condemned the far—right demonstrators and announced that police forces across the country are to co—operate more on tackling violent disorder. police have released images of eight other people they want to identify after objects were hurled outside a hotel housing migrants during a protest in aldershot. let's speak to adam hadley, the founder of tech against terrorism, an organisation dedicated to disrupting terrorists online.

thank you very much for your time, adam. there was an awful lot of disinformation spread about this online. ., . , disinformation spread about this online. ., ., , ., online. unfortunately, what we saw it as there was _ online. unfortunately, what we saw it as there was a _ online. unfortunately, what we saw it as there was a huge _ online. unfortunately, what we saw it as there was a huge amount - online. unfortunately, what we saw it as there was a huge amount of i it as there was a huge amount of coordinated activity before the protest, during and after. what we do is monitor the use of the internet by the extreme far right and by violent extremists on the internet. what we find is there is a huge amount of material available and often the social media platforms will only remove this when it is too late. ~ ., ., late. we heard from the prime minister said _ late. we heard from the prime minister said yesterday - late. we heard from the prime minister said yesterday that i late. we heard from the prime - minister said yesterday that violent disorder was whipped up online. what can be done about this? how can we track these people and stop it happening?— track these people and stop it haueninu? . ., , , happening? part of the problem is that many of _ happening? part of the problem is that many of those _ happening? part of the problem is that many of those seeking - happening? part of the problem is that many of those seeking to - happening? part of the problem is l that many of those seeking to drive grievance and divide society are really good at using social media

platforms and their own websites to do so. often what we find is extremists and also nation states working to provide this information will use a variety of platforms and what we feel is needed is more of a cross—platform approach. the problem however is one extremists and others report from platform to another. i think part of the problem here is that one person to post something and get shared and shared again, so it is numerous people posting something and in that volume it almost seems to become facts when there is a lot of people saying the same thing, then you get delivered that as part of your social media suggestions. is this a case of those social media companies trying to prevent those algorithms from doing that, from stopping that? do we need

humans here, i guess is what i'm saying? humans here, i guess is what i'm sa inc? ~ ., humans here, i guess is what i'm sa inc? ., �* humans here, i guess is what i'm sa in? ., ~ humans here, i guess is what i'm sa in? ~ ., ~ ., ., saying? we do. and the social media latforms saying? we do. and the social media platforms have _ saying? we do. and the social media platforms have spent _ saying? we do. and the social media platforms have spent fortunes - saying? we do. and the social media platforms have spent fortunes trying | platforms have spent fortunes trying to protect their platforms. there are sophisticated bot networks that will often identify polarising content then automatically start sharing it. what we found with the recent protest is that in some cases there is content shared on tick—tock or facebook or wherever and potentially it is just one or two images, but in these cases we find that sometimes within minutes this content has been shared hundreds of thousands of times and this is part of the problem. it only takes one or two pieces of content, you can't become barrel extremely quickly. the challenge here is that platforms are often unable to respond quickly

enough, and government as well. we are calling for more coordination between government and platforms because the reality of the situation is you have to respond within minutes, not ours. i is you have to respond within minutes, not ours.— is you have to respond within minutes, not ours. i suppose the roblem minutes, not ours. i suppose the problem as— minutes, not ours. i suppose the problem as there _ minutes, not ours. i suppose the problem as there is _ minutes, not ours. i suppose the problem as there is no _ minutes, not ours. i suppose the | problem as there is no correction. if you get something wrong on social media you don't have to post again to say actually i was incorrect, just stays there.— to say actually i was incorrect, just stays there. exactly, and in many cases _ just stays there. exactly, and in many cases it — just stays there. exactly, and in many cases it is _ just stays there. exactly, and in many cases it is too _ just stays there. exactly, and in many cases it is too late - just stays there. exactly, and in many cases it is too late then. i just stays there. exactly, and in - many cases it is too late then. even if there is a correction people will stand to believe it anyway. this is the asymmetry of the problem. it is so easy for this information to get out there. it is very difficult to counter it. it out there. it is very difficult to counter it— out there. it is very difficult to counter it. , ., , , counter it. it is a very complicated issue. counter it. it is a very complicated issue- adam. _ counter it. it is a very complicated issue. adam, we _ counter it. it is a very complicated issue. adam, we appreciate - counter it. it is a very complicated issue. adam, we appreciate your. counter it. it is a very complicated - issue. adam, we appreciate your time here on bbc news. now it's time for a look at the weather with carol kirkwood.

hello again. this morning's mist and fog across parts of southern and south—eastern england continue to lift. if you have an allergy to pollen, the levels today are higher, more than we have seen in recent days. generally speaking they are low to moderate and we are talking wheat and nettle pollen in particular. the chance of a few showers in eastern england, but for most it will be dry, sunny and warm. we have a cold front bringing in some rain, cloud and strengthening winds to the west. ahead of it the cloud will build with one or two showers. temperatures 16 to 27, but we could see 28 or 29 and here it will still be muggy in the south—east. in the evening and overnight the weather front continues to sink southwards and eastwards. it starts to break up and turn more showery. ahead of it, clear skies and feeling muggy, behind it clear skies but with scattered showers. but it will feel fresher behind that cold front. temperatures in scotland

and northern ireland nine to 12 degrees, 15 to 17 as we push further south, it is still muggy in the south. on saturday this is the weather front pushing towards the south—east. it could rejuvenate in the south—western end. although we start with cloud and showers, we could see heavier showers in the channel islands and hampshire and dorset. to the north of that, drier with sunshine and again scattered showers, especially across scotland and northern ireland. fresher for more of us tomorrow, but still quite muggy across the south—east even though the temperatures will be that little bit lower. as we head through saturday night and into sunday, we say goodbye to the weather front with a ridge of high pressure building across us, but then we have the next area of low pressure coming in during the day. on sunday a lot of cloud around, some sunnier breaks in eastern areas and we could catch one or two showers from the thickest cloud, but through the day the wind will strengthen and the cloud will build and the rain will arrive in the west.

temperatures 1a to 2a, but feeling fresher across the board. beyond that into the new week it still remains fairly unsettled. there will be showers with rain at times and there will still be sunshine and temperatures round about where we would expect them to be at this stage.

live from london, this is bbc news. free at last — three americans and a kremlin critic imprisoned in russia arrive on us soil, part of the biggest prisoner swap deal since the cold war. myjob is to make sure, number one that they don't get them, and if they do, we get them back. i don't buy this idea that you let these people rot injail. the deal frees 2a prisoners and two minors held in seven countries, including convicted russian fsb hitman vadim krasikov. the body of the hamas political leader ismail haniyeh is now in qatar, where a special prayer service has been held before his burial north of doha. in the uk, seven men are charged with violent disorder after a riot
