hello, this is bbc news. the headlines at one o'clock... ahead of the women's 100 metres final this hour — heartbreakfor team gb's dina asher—smith — who failed to qualify. she's now been forced to pull out of the 200 metres due to a hamstring injury. i'm a i'm a competitor... ye have seen me p0p my i'm a competitor... ye have seen me pop my hamstring when i was younger, in the 200 i would do it... that is the kind of athlete i am. but he is wiser than me. but there's gold elsewhere. a �*super saturday�* at the tokyo olympics for team gb so far. gold — and a world record — in the li—by—ioo—metres mixed medley relay. team work makes the dream work —

another gold in the triathlon mixed relay event — where jonny brownlee won his first gold medal at his third olympic games. afghan security forces are battling to defend three key cities from advances by the taliban. reports say militants have breached front lines in herat in the west. donald trump's been ordered to hand over his tax returns to congress. the usjustice department overturned a ruling — made when he was in office — that the information could stay private. medical experts are warning that an oxygen monitoring device, called an oximeter, works less well for people with darker skin tones. bbc news understands the government is no longer considering making it compulsory for students to be fully vaccinated to attend lectures in england. and a british satellite has launched from french guiana — in a boost to the uk

tele communications industry. we start in tokyo, at the olympics, where after a great start to the day for team gb, things have taken a turn. dina asher—smith's games appear to be over after she indicated she would withdraw from the 200 metres. that follows her being unable to qualify for the 100 metres final. earlier, team gb added two more gold medals to their tally, in new mixed events. the first came in the triathlon mixed relay. then, in the pool, taking the total gold haul so far to eight. for a full round up of the action at the olympics this morning — let's cross to austin halewood at the bbc sport centre. good afternoon. yes, she was one of team gb's great medal hopes for these games. but there's been huge disappointment for dina asher—smith.

after failing to reach the final of the women's one hundred meters, she revealed she'd been struggling with a hamstring injury, and she'd had to pull out of her stronger event, the 200—metres. it was clear she wasn't her usual self in the semis of the 100 — she finished third, behind defending champion, elaine thompson—herah. and asher—smith's time of 11.05 seconds wasn't quick enough to make it through as a fastest loser. she was emotional as she explained what she'd been going through. iam going i am going to pull out. johnjust had that conversation with me and that's the one that... because as the reigning world champion, you just cut and i was in such good shape, you know that the olympic champion is not too much of a further step. champion is not too much of a furtherstep. i champion is not too much of a further step. i am champion is not too much of a further step. iam really champion is not too much of a further step. i am really proud to have been able to execute my races

here today and i really proud of everything that i have done until this point, but when you're talking about the standard that want to be at and the line capable of, sometimes... you know there's plenty more championships for me to come and kill. asha philip is also out, afterfinishing last in hersemifinal but britain's daryll neita has made the final — she ran 11 seconds exactly, to go through as one of the fastest losers. it was, predictably, the two—time olympic champion shelly—ann fraser—pryce who won that race in the fastest time of the semis — but absolute delight for neita. the final is at 1.50 uk time. and in the men's100—metres heats, european champion zharnel hughes ran a season's best time of 10.94, to reach the semi—finals along with team—mate cj ujah. but away from the athletics, it's already been a golden saturday for team gb in tokyo... and it's been a day when team work has been the key to success... firstly in the new triathlon relay and then after that back in the pool — where the british team are enjoying their most successful games, in over a century,

as adam wild reports... the triathlon will be golden for great britain. it's the mixed medley relay, great britain win the gold by miles. for all the individual brilliance, in the tokyo today it was teamwork that triumphed. super saturday had barely begun, but team gb was already looking at four new olympic champions in this, the inaugural triathlon relay. jessica learmonth led the way for britain. then the turn ofjonny brownlee. individual bronze in london, silver in rio, this his final olympic race, a last chance to complete the set. georgia taylor—brown had given britain a 21 seconds advantage and, although alex yee was dramatically caught for a moment, when he came to the finish, he and gb were in a class of their own. he will win the gold.

four new british olympic champions before breakfast. forjonny brownlee, gold at last. the olympics? i've completed it. i've been waiting for that one. yeah, it feels absolutely amazing. third olympics and to finally walk away with olympic gold, and we did everything we possibly could. whilst over in the pool, team gb have surpassed expectations. now a moment for the team's finest to come together. the mixed medley relay, another new olympic event. in the company of the finest swimmers on earth, britain have already proved they can excel. here, they were doing it again. kathleen dawson gave way to the peerless adam peaty. he did what he always seems to do. before james guy powered britain into the narrowest of leads. and here was anna hopkin in the final leg. great britain are going to win their fourth gold in the swimming pool. one word that has changed the whole team is belief. we've got champions who believe we can win, champions who believe

we can get world records and if you've got one belief, you build everything around that. two team relays, two olympic team titles, another golden day for team gb. emma wilson has taken windsurfing bronze on her olympic debut. she was already guaranteed a medal going into the final, after winning four of her 12 races — and she crossed the finish line in second place — but with cumulative scores counting, that gave her bronze behind china's lu yun—zoo and the rio champion, charline picon, of france. that's all the sport for now but there's lots more on the bbc sport website, including the start of the football league season in scotland and the build—up to the second lions test against south africa this afternoon, ben. we saw the gold medal performance in the pool for team gb there. we can now speak to james

james cried when they won the four by two, we cried. we are going to those emotions with them. it is 20 years in the making. to get the gold medal he dreamt as a boy, did everything, did he ever think he was going to get it? i don't know, i can't answer that question, that is the pinnacle of any sportsperson to get an olympic gold. to get an olympic medal, he already has two from rio, but to get the gold, is far and if from rio, but to get the gold, is farand if you, from rio, but to get the gold, is far and if you, see go through all the emotions. we have cried, sung together... even though he is one, because it is emotional and we are delighted for him and all the team. you wish to know him very well and have watched him develop as a swimmer —— you obviously know him very well. can you give us an idea what his mindset has been like? what does it take to to that level of competition?— does it take to to that level of cometition? ., . ., , competition? you change coaches about 18 months _ competition? you change coaches about 18 months ago _ competition? you change coaches about 18 months ago and - competition? you change coaches about 18 months ago and had - competition? you change coaches about 18 months ago and had a i competition? you change coaches i about 18 months ago and had a great career, was world champion, but he

wondered for a couple of years whether his performance wasn't great, thought he was due a change and change to a new coach in bath where he was already training, and sport psychologists looked after in and the difference this year going to the olympics, physically fit, the all get in and out the same fitness, it's the mentality. i think he was in a much better place mentally, stable, knew exactly what to do, had great structure around him in great discipline. the one thing that stood out for me more than anything with the british swim team is the culture, and i think that this help the team so much. if you watch them, they are one team. that has been the difference. james is a team player. he gave up his individual, which i believe he would have got the bronze with the time he swam in the medley relay this morning, because he knew deep down that they had a chance of the gold and the world record. and they committed to it. the main set was any good place and that has been

the difference for me, where they are mentally as a team, and the culture of british swimming. that has been the difference. $1150 culture of british swimming. that has been the difference. also talk about that particular _ has been the difference. also talk about that particular subject - has been the difference. also talk about that particular subject this i about that particular subject this week in the opening week of the olympics. we have seen a few moments ago the heartbreak a1, having to pull out of the 200 metres due to injury. i guess that is part and parcel of being an athlete at these games, isn't it? —— for dina asher—smith. games, isn't it? -- for dina asher-smith.— games, isn't it? -- for dina asher-smith. that is part of the “ourne asher-smith. that is part of the journey and _ asher-smith. that is part of the journey and dina _ asher-smith. that is part of the journey and dina asher-smith i asher-smith. that is part of the l journey and dina asher-smith will journey and dina asher—smith will bounce back, she knows to get what she wants yet to be at the right top of her form she wants yet to be at the right top of herform and she wants yet to be at the right top of her form and they have made a call. sometimes it is difficult to make that call. but it is the right call. if coach think that is the right call, they make the call, and she will bounce back. she is an amazing athlete and a winner, and sometimes you have to make a really difficult choice. as james had a couple of years where he performed badly and wondered and was lost in

the sport, he bounced back and is now a double olympic champion and i'm sure dina asher—smith will bounce back and be even stronger. well, go get some sleep, thank you forjoining us on bbc news. staying on the games — and tokyo has reported that new daily coronavirus cases have surged to a record high of a,058. a spike in cases in recent days has prompted an extension of the capital's state of emergency. it's also been expanded to cover other parts of the country. olympics organisers have reported 21 new games—related covid cases. no athletes are affected by the latest cases, but this takes the total games—linked number of infections since july the 1st to 2a1. to afghanistan, where the fighting has escalated around three strategic cities, that security forces are trying to defend from taliban militants. the insurgents have intensified their attacks on herat

in western afghanistan and clashes are continuing in lashkar gah and kandahar in the south of the country. with us—led foreign forces nearing a complete withdrawal of troops, the taliban have made swift territorial gains over the last two months. our chief international correspondent lyse doucet has been speaking to the eu's envoy for afghanistan tomas niklasson in kabul, on how serious this moment is. the best realistic scenario is one where the taliban offensive is held back. where there is a bit of push back, a bit of rebalance. and all these nice words that still mean further suffering and deaths, a number of afghans dying on both sides. more people on the run, leaving their homes. but that with this recalibration, rebalancing, the taliban would then, after some time, be ready to come back to negotiations in doha

or start negotiations in doha in earnest, to find a negotiated solution to afghanistan's problems. earlier i spoke to lyse, from kabul, where she gave us the latest of the taliban's advancements. the taliban went on the offensive a few weeks ago and took people by surprise. how quickly they were able to overrun districts in all parts of afghanistan, even in northern afghanistan, which is not their traditional stronghold. of course, some of the districts they overran had little more than a flag in the district centre, the afghan national security forces retreated tactically or they did not put up a fight. in some cases, the fighters went over to the taliban side. a moment of reckoning is starting now as the taliban push into strategic provincial capitals on all sides of the country. we have known that the taliban have been pushing towards these capitals,

surrounding some of them for some time, but now actually inside, and in some cases, as far as city centre. but the afghan national security forces is supported in some places by continuing us air strikes, pushing back the taliban. the fight is now under way. and it is certain to continue for some time to come with dire humanitarian consequences. what about the negotiations? what is the realistic hope here of halting the violence? there have been endless calls for a ceasefire. notjust from the afghan government but by afghans across the country who are absolutely exhausted and fearful about this war. it is, after all, a a0—year war. most afghans have never known anything but war. i was just recently in the gulf state of qatar where the taliban have one of their political offices,

a high—level government delegation had gone there as well to try and see if they could kick—start the long—stalled negotiations, but it is clear the taliban want to push forward on the battlefield to gain advantage at the negotiating table. if not, some beleive, for some of the taliban leaders, to try and achieve a military victory, so the government too is now emphasising that as much as they want peace, the focus is on the front, the fighting front. medical experts are warning that an oxygen monitoring device, called an oximeter, works less well for people with darker skin tones. nhs england and the medicines regulator, the mhra, say pulse oximeters can overestimate the amount of oxygen being taken in. authorities are advising patients to speak to health care professionals before using the devices and not to rely on a single reading. although a valuable clinical tool, what we do know is that clinicians

are increasingly becoming aware of the potential errors or inconsistencies in the interpretation associated with pulse oximeter readings, so we need to have these points in mind when using these devices. this is an example of health inequalities that we see, an example of the disproportionate kind of stratification we have in terms of accessing health care. what we do know is that oxygen is probably the most common drug used in the care of patients who present medical emergencies, and health care professionals are increasingly reliant on the pulse oximeter to detect early deterioration, and to inform clinical decision—making, so we need to get this right. american military forces are said to have boarded an israeli—operated oil tanker after a british and a romanian member of its crew were killed by a reported drone strike. an israeli government minister's accused iran of exporting terrorism in the wake of the alleged attack

off the coast of oman. the usjustice department says tax returns belonging to the former president, donald trump must be handed over to congress. the decision reverses a previous ruling. officials now say lawmakers have legitimate reasons for asking to see the documents. our north america correspondent, david willis, reports. donald trump has fought hard to prevent the release of his tax returns. this isjust a continuation of the most hideous witch—hunt in the history of our country. this latest ruling could mark the beginning of the end of his ferocious effort to keep those documents out of the public eye. then treasury secretary steven mnuchin's refusal to comply with a subpoena back in 2019 prompted a two—year battle for documents including asset, income and tax payment data on the part of the democrat—led house ways and means committee, which is investigating potential conflicts of interest on the part of the former

president and the possibility of foreign interference. now, in a 39—page ruling, the usjustice department has reversed a ruling made when trump still in office and has ordered the treasury to release six years' worth of trump tax returns — a move hailed by the house speaker, nancy pelosi, who called access to the documents... every president since richard nixon has disclosed details of their tax returns, the one exception being donald trump. he claimed before he was elected that his records were under audit by the authorities, a process that was apparently under

way by the time he left office. republicans say the entire issue is politically motivated. they have denounced thejustice department decision and donald trump is widely expected to challenge it in court, meaning that if those highly anticipated documents are to be made public it could still be many, many months away. david willis, bbc news, los angeles. bbc news understands the government is no longer considering making it compulsory for students to be fully vaccinated to attend lectures in england. earlier our poltical correspondent pete saull gave a bit more background behind the decision. you remember boris johnson you remember borisjohnson about ten orso you remember borisjohnson about ten or so days ago... from the 10th of september if you want to attain a club or other large venue with lots of crowds you have to show proof of double vaccination. lots of other settings have been considered by ministers, one suggestion was that once the university students return to campus in september,

they will have to show proof of double vaccination to go to lectures, to even stay in their halls of residence. now, that has been looked at, i'm told that does not have been shelved, that particular idea. we don't quite know why. certainly there has been a big backlash to idea of the widespread use of vaccine passports among conservative mps. they leader of the house of commons jacob rees mogg is saying last night that that is not the end of the idea of a vaccine passports but we should protect our ancient freedoms. a sense that people are instinctively uneasy about having to show papers to get in anywhere, but if that is a price worth paying to protect people's public health that is something people might be able to accept. certainly on university campuses it sounds like this

will not happen now. —— will not happen now. if two women have been seriously injured by a falling tree after strong winds struck the south of england. emergency services were called to ubbeston in suffolk on friday evening. police say the two, who are in their 20s were at an outdoor party. it came after storm evert led to gusts of winds nearing 70mph across cornwall — prompting a number of rescues. the uk tele communications industry hopes a satellite that has gone into orbit will help maintain its global leadership in the sector. a quarter of the world's big telecoms spacecraft are manufactured in britain, and the new quantum platform is billed as the market's next—generation product. quantum was launched on an ariane rocket from french guiana last night. here's our science correspondentjonathan amos. another rocket climbs skyward to bolster a sector that europe, and the uk in particular, has come to dominate — the business of telecommunications satellites. there are hundreds of these spacecraft overhead, bouncing tv, phone calls, broadband and other data services around the planet. but the new satellite

going into orbit, called quantum, represents a big step forward in technology. while traditional telecom spacecraft are configured before launch to do very specific tasks, quantum has been built for flexibility. it is the sector's first fully reprogrammable spacecraft. it is able to rapidly change the coverage, bandwidth, power and frequency of its signals. one of its uses will be for disaster response, providing emergency communications to the teams that are sent to help people in places hit by catastrophic floods or earthquakes. quantum's manufacturers in the uk, that is airbus and surrey satellite technology ltd, will incorporate the prototype's technology into their future spacecraft, hoping to maintain their world leading status in what has become a highly competitive field. emily gravestock is head of applications strategy

at the uk space agency. a giant in the sky. three and a half tonnes going up last night. they deliver all sorts of services we rely on on a day—to—day basis. this is a telecommunications satellite and it is going to deliver the ability to make phone calls, deliver messaging and internet to people in aeroplanes, supporting communications with boats in the maritime sector, right across the middle east, north africa, mediterranean and all—round that part of the world, for this satellite in particular. the beauty of it and the world—first about it as it will be able to change what it does as our needs here on earth change. if we need more bandwithin a particular point, it will be able to change the focus of this beam to provide that to the people of earth. traditionally these are configured in the factory, so how much of a breakthrough is that?

that is in an enormous breakthrough. it really does give the uk the leading edge in the technologies of the future, because the fact that this is reprogrammable and going to be up there for around 15 years in its lifetime means that as our needs change, if you think back 15 years ago how our lives were different, in 15 years time is likely they will be different again, so the fact we have got and delivered this from the uk is a real milestone for space technology. we are already at the point where airbus is receiving orders for another version of the same type of technology and capability, putting them at the forefront of a major space initiative. the manufacturing of this has been led from the uk but had involvement from elsewhere. how important is thatjoint approach to these types of satellites? i think working within the european space agency and the member states family, for the uk space agency, it is absolutely brilliant. we are the leaders in europe for the type of technology through our investment in programmes in esa, but pairing up with other member states and europe means we can bring the best

of the best and take companies like airbus and others and bring people together to work on it. more than 1000 people across europe have worked on the satellite over the last few years as it has gone towards orbit and actually bringing together the european family to deliver through esa working with us is brilliant. going forward, what can we now learn that it is in orbit? we can learn that we have the opportunity to revolutionise space technologies, as we realise they underpin a lot of what we do on earth, satellite broadcasting, remote medicine and health care, utilisations like that. what this can do is change with us on earth. that is what it will give us in the future, the opportunity

to manipulate the satellites we put in space, to grow with this to mean there will be less space junk in the future. the first night of the proms took place at the royal albert hall last night. for the first time since 2019 audiences were back, after providing proof of a negative covid test or double jab. more than 2,000 musicians from 30 orchestras will play every day over the next six weeks, as live music returns on a scale not seen in the uk since the start of the pandemic. the singer kt tunstall has been speaking to the bbc about her decision to pull out of an upcoming us tour due to problems with her hearing. the brit award winner, went completely deaf in her left ear three years ago. earlier this month she noticed the early signs of deterioration starting in her right ear and decided to act. she's been speaking to our entertainment correspondent colin paterson. kt tunstall has been playing live for three decades, often doing 200 shows a year.

next week she wants to start a three month us tour with hall and oates but what's happening to her hearing has caused her to pull out. it's almost like a siren goes off and you suddenly get this — "woooo" — and it'sjust a pulse of a noise. the other thing that you can get is that suddenly you can't hear anything and it feels like someone's put a vacuum over your head. her plan is now to space out live shows allowing more recovery time, but the brit award—winning singer has been struggling with her hearing since the end of 2007. i got off a long haulflight, and i was actually going to a spice girls concert, and i had a nap before i was going to go to the gig, and i woke up and i felt really discombobulated and something was up with my left ear and i had a really, really loud ringing.

i couldn't hear things like the shower, or running water, i couldn't hear crisp packets, i couldn't hear the indicator on the car. kt tunstall believes her hearing problems are caused by the stress to her body of being on the road rather than by loud music. things got worse in 2018 during a us tour when she went permanently deaf in her left ear. when i saw a couple of specialists, they don't really know a lot about the inner ear, it's so fine and so complex. i was also told that the more deaf you go, the less likely it is that you'll get your hearing back and i was at like 98% or something. i can't hear anything in that ear. so i can't wear a hearing aid in that ear because there's nothing going in. your hearing is deteriorating rapidly. deafness in musicians was a theme explored in the oscar—winning film sound of metal. i can't hear you! do you understand me? ican't...|'m deaf!

kt tunstall thought it was excellent and hopes it leads to more understanding of the issue. have you thought about what your life would be like if you are no longer able to play live? i would be really, really sorry to not be able to do it anymore but i think that the decision that i'm making with how i'm approaching my career here is to really carve a way of life that allows me to keep playing live. totally intend to continue, butjust at a slightly different pace now. colin paterson, bbc news. cheering and applause. after 17 years at radio 1, annie mac has presented herfinal show on the station. the last 17 years have been the most amazing, magical experience and, yeah, thank you so much for listening.
