this is bbc news — the headlines at 8: super saturday comes round again for team gb in the olympics — with a gold and a world record in the 4x100 metres mixed medley final. team work makes dream work — another gold in the triathlon mixed relay event, and finally a first gold medal forjonny brownlee at his third and final olympic games. and victory for the fastest woman in the world — elaine thompson—herah, ofjamaica, in the women's 100 metres. we'll be taking a look at how team gb�*s success in tokyo is reflected in the papers tonight at 10:30 and 11.30. afghan security forces have been battling to defend three key cities from advances by the taliban. medical experts are warning that an oxygen monitoring device, called a pulse oximeter,

works less well for people with darker skin tones. borisjohnson and his wife, carrie, have announced they are expecting a second child. their first child, wilfred, was born in april last year. good evening. team gb have won two more gold medals at the tokyo 0lympics, both in new events where men and women compete together. there was further success for the swimming team, who took gold in the 4x100 metre mixed—medley relay. 0ur sports editor dan roan was watching the action. a first for the olympics, but a familiar feeling for team gb. a third triathlon medal today in the inaugural mixed team event — but, this time, gold.

with each athlete facing a 300—metre swim, 6.8 kilometre bike ride and two—kilometre run, jessica learmonth got britain's bid off to a great start, beforejonny brownlee then extended the lead in his third and final 0lympics. team gb still had their two silver medallists from the individual events to come — first georgia taylor—brown and, for the final leg, alex yee, who powered home to seal a 1a—second victory. after a bronze and silver in his previous two games, brownlee finally emulating brother alistair and claiming olympic gold. it's something that i've wanted to do for a long time. i've chased that dream for a long time. i've seen my brother, obviously, achieve it twice, and now i've done it and it feels amazing. introduced to try and improve gender balance, the new mixed team events have been one of the features of the games here in tokyo, and britain are certainly enjoying them. team gb swimmers have already had a remarkable 0lympics, but it got even better in the ax100m

mixed medley relay. great britain are going| to win their fourth gold in the swimming pool! anna hopkin sealing a stunning win and new world record after kathleen dawson, adam peaty and james guy had established a lead. this a seventh medal for the team here — one more tomorrow and it will be british swimming's best ever games. dan roan, bbc news, tokyo. britain's fastest—ever woman, dina asher—smith, has spoken of her devastation after failing to reach the final of the women's 100m because of an injury. her team mate, daryll neita, finished eighth in the race. asher—smith has now pulled out of the 200m race. this report from our sports correspondent, natalie pirks. obviously, the competitors... this is for the start, we'll let it go. we'll let the start go and let me cry! the customary smile replaced with tears. the fastest woman in british history had been hiding a secret. dina asher—smith!

just five weeks ago, she'd been told there was only a 2% chance she would make it to the start line after a torn hamstring. elaine thompson—herah there is going to win it. | it's going to be del ponte who takes second place. i and dina...she'sjust not finishing. she gets out well - and couldn't hang on. out of the final and minutes later, the reigning world 200m champion confirmed she was out of that too, but would still run the relay. my idea for this 0lympic cycle was complete dominance and obviously, ha! didn't manage it this time but, obviously, we have three more years till the next olympics and i know the kind of shape i'm in, i know the calibre of athlete i am and i know how talented i am. so it's frustrating to not be able to put it out when it matters, but, at the end of the day, with the cards that i've been given i did very, very well and in no way does this change anything that's going to happen in the future. well, daryll neita might not have been the name on everyone�*s lips but making the 100m final is a huge achievement. she's the first british woman

to do so since 2008. but this would be a tough ask from a field stacked with talent and speed. elaine thompson—herah's just got the lead at the minute. i and it is going to be the defending champion makes it two in a row! . 10.60 — it's an olympic record! a jamaican 1—2—3. the pace was blistering, the celebrations between them somewhat frosty — not that elaine thompson—herah cared. my chest is tight because i'm over—happy. i'm so...but god it's amazing. heartbreak, then, for the queen of british sprinting but the jamaican dynasty continues its reign. natalie pirks, bbc news, tokyo. in other olympic news: all three team gb athletes entered in the women's 800 metres have qualified for the final — for the first time ever. 19—year—old keely hodgkinson timed her run well to finish second in her heat. she'lljoin alex bell and jemma reekie in the final on tuesday. on her olympic debut, emma wilson has won bronze

in the women's windsurfing. the 22—year—old's mother, penny way, is a former world champion, who narrowly missed out on a medal in the 1992 and 1996 olympics. and four—time olympic champion simone biles has withdrawn from two more gymnastics events — sunday's vault and uneven bars finals. she withdrew from tuesday's women's team final as well as thursday's individual all—around final, saying she had to focus on her mental health. as we've been saying, it was an historic win for team gb in the pool. great britain claimed a fourth swimming gold at an olympics for the first time in 113 years. the quartet of kathleen dawson, adam peaty, james guy and anna hopkin won the inaugural ax100m mixed medley relay in a world—record time. earlier, i spoke to mark skimming, who coached anna hopkin at bath university. i was trying, actually, to be really quiet and not wake up other people in the house... so i was cheering loudly in my head

but not so much in the actual room. it's a mixed event, this. we've been talking about that a lot today. that meant that, if i've got this right, anna hopkin on the final leg was up against the fastest male swimmer in the world. what must that have been like for her? and she won! yeah, she won. i don't think they take into account what they're doing. they get in and do theirjob. each country races in a different order. i mean, we swam female, then two men, then a female, whereas the americans swam in a male, two females and then a male. so it's about getting in and doing the bestjob you can. but, yeah, i'm pretty sure if he was a little bit closer, he would've maybe caused them a few worries. and when you coached anna, did you suspect that she had not just the physical talent but their mental temperament to be able to get gold? anna is a lovely person. she's so nice,

she works really hard. she just wants to get better. she wants to enjoy it, she loves racing. she is very talented, both physically and mentally and when she came back into swimming, when she came to university to study, all she wanted to do was swim and swim a few relays and have a bit of fun and we did that and she swum quite fast. and she swam quite fast. then, seven years later, she's just steadily upped what she's doing and, yeah, she's gone on and created a pretty good record for herself. individual 100 final, relay gold medallist, world record holder. and do you get a sense from her that the relays must bring out something particularly special, above and beyond those individual events? anna's always loved the relay as long as i've known her. she's always swam class, she loves being a part of a team.

she enjoys the camaraderie and she likes to race and she likes to win. i've seen her go fast in relays for seven, eight years now and it's great to watch. you could put her on the back end of a relay and she would perform every time. have you been able to send her messages at all or get through to her in the olympic village? no, i'll wait till she comes back. she's got a lot going on! she's pretty busy, so i'll send her a message when she gets back. mark, could you resist the temptation of coaching from afar during her race? want to wake anyone up, "do this stroke a little differently, do that a little differently?" no. when they race, it's just more about, go, go faster, go now, go, go! it's not about what they're doing right and wrong when it's in the heat of the moment. i sort of do that afterwards when

they come back and i talk to them. a reminder, we'll find out how team gb's medal success — and many other stories — are covered in tomorrow's front pages at 10:30 and 11:30 this evening in the papers. our guestsjoining me tonight are the journalist james lewer and sunday times education editor sian griffiths. fighting has been raging around three major cities in southern and western afghanistan, as the taliban try to seize more ground from government forces. at one point, taliban militants werejust 300 metres from the governor's office in lashkar gah, the capital of helmand province, but they have now been reportedly pushed back. there's also been battles in herat and kandahar. our correspondent, secunder kermani, has the latest from the afghan capital kabul. this has certainly been the most serious moment, i would say, in the weeks of intensified fighting that we've been seeing in afghanistan. the taliban already control vast

swathes of rural territory, they've captured that in the last couple of months, but now they're trying to take their first city. earlier this evening they advanced right into the heart of lashkar gah city — that's the capital of helmand province. following the arrival of afghan special forces, there were heavy clashes and we understand that fairly recently the taliban were forced back from the centre of the city. but i was just talking to one local resident from lashkar gah, and he was saying, "look, even if the taliban "don't manage even if the taliban don't manage to capture the city on this occasion, this has been a powerful assertion of their strength." and he also said that the militants had taken up the positions inside the homes of a number of ordinary families — that's, of course, going to make it harder for the security forces to dislodge them. as you say, fighting has been raging elsewhere, too, in and around the cities, notably of herat in the west of the country and kandahar in the south. us air strikes had to be employed last night to support government efforts in herat — that's despite the fact that around

95% of american forces have now been withdrawn from afghanistan. you've got tens of thousands of people who are actively being displaced by this fighting right now, and that's adding to around 300,000 or so who were already displaced even a number of weeks ago. a number of other afghans, many other afghans, are planning, or at least considering what their options are, when it comes to leaving the country. i've been looking at social media groups set up by people smugglers, offering routes out through iran and into turkey. the people smugglers who are operating those groups are really being inundated with requests by people. the passport office here in kabul recently has seen large queues, as well, many people going there trying to renew their documents in order to apply for legal reasons to get to apply for legal visas

to get out of afghanistan. the fear that many people have is that at the end of august, when the international military mission in afghanistan formally comes to an end, the violence might get even worse. to the pandemic now — and the latest government figures on uk coronavirus infections show that there were just over 26,000 new cases in the latest 24—hour period, meaning an average of 27,464 new cases per day in the past seven days. 71 deaths were recorded in the last 2a hours — that's an average of 70 deaths a day in the past week. the latest figure for the number of people in hospital with covid is just below 6,000 — it hasn't been updated from yesterday. onto vaccinations now — more than 88% of uk adults have now had theirfirstjab and more than 72% are now fully vaccinated. meanwhile, bbc news understands the government is no longer considering making it compulsory for students to be fully—vaccinated to attend lectures in england. ministers still plan to require

people to have both jabs to enter nightclubs and other large indoor venues from september. but it's now thought that the idea of introducing vaccine passports on university campuses has been shelved. nhs england and the body that regulates healthcare products are issuing new guidance on pulse oxygen meters — also known as oximeters — after it was found that the devices can overestimate oxygen levels in people with darker skin. with more, here's amara sophia elahi. ranjit senghera marwaha caught coronavirus in december last year and eventually ended up in hospital with seriously low oxygen levels. so, basically, flip the lid, put yourfinger in... she had been monitoring her levels at home with a pulse oximeter, but the meter consistently told her she was in safe levels even as she increasingly struggled to breathe. when i went into hospital, the first thing they said was, "you really did leave it too late." had you left it any longer,

i would have been straight into icu. there is growing evidence that such monitors can overestimate oxygen levels in people with darker skin tones by 2%. that's led to nhs england and the body that regulates the use of medical devices, the mhra, issuing new advice. they say people shouldn't use the devices at home without speaking to a medical professional and to monitor oxygen levels over time. low oxygen levels are a primary indicator of a serious covid infection, and those treating patients in hospital say they've expressed concerns about the use of the technology on minority ethnic individuals. it is something i would pick up on at least once a day, with maybe two or three patients on a daily basis. it is quite possible that someone's oxygen levels were measured and they seemed normal when, actually, they were truly low, and because they seemed normal they might have been sent home, and denied the steroids and oxygen which we would normally have been giving to patients, and it's possible that that therefore may have led to them becoming more unwell and potentially even dying. oxygen is one of the most common

treatments given in medical emergencies, and doctors stress accurate readings are vital when assessing patients. nhs england say they are keeping the situation under review and have commissioned further research into the issue. amara sophia elahi, bbc news. the headlines on bbc news: elaine thompson—herah ofjamaica has won the women's 100m final at the tokyo games — in a new olympic record time of 10.61 seconds. medical experts are warning that an oxygen monitoring device, called a pulse oximeter, works less well for people with darker skin tones. and, borisjohnson and his wife, carrie, have announced they're expecting a second child. their son, wilfred, was born in april last year. police are investigating after the body of a five—year—old boy was found in a bridgend river. officers made the discovery in the early hours of this morning. liz clements reports.

it was at 5:a5am this morning when south wales police were called to reports of concern for a missing five—year—old child in the sam area of bridgend. in a statement, they say officers attended and found the body of the child in the ogmore river near where i am in pandy park. he was taken to the princess of wales hospital, where it was confirmed the child had died. an investigation is ongoing into the circumstances of the incident, and the police are keen to hearfrom anyone who was around the area at 5:45 this morning who may have information about how the child ended up in the water. they have called it a tragic incident and are asking the public not to speculate on social media, as this is an active investigation. the family is being supported by specially trained officers. the prime minister's wife, carriejohnson, has announced she is pregnant. this will be the couple's second child together. announcing the news on instagram, carriejohnson also revealed

that she had a miscarriage at the start of the year. she said, "i feel incredibly blessed to be pregnant again but i've also felt like a bag of nerves." the labour leader, sir keir starmer, has tweeted, "congratulations to carrie and borisjohnson on the happy news that they're expecting another child. i'm very sorry to hear of carrie's earlier miscarriage. i'm sure that her speaking out will be of comfort to others. every best wish to them both." zoe clark—coates is the chief executive of the mariposa trust — an organisation which offers support following the loss of a baby during pregnancy or infancy. she said many women find it hard to speak openly following a miscarriage. it can be truly difficult. i think it's been, conventionally, for many years a taboo topic, to talk about any type of baby loss, and that is one of the things we're trying to do as a charity to break down that to do. down that taboo.

because people need to talk when they have gone through loss. it is how you process grief. how would you advise people to respond when the subject is raised by people like carriejohnson who talk of this loss? i think you just listen, that you do not try to give platitudes, or make people think that their loss is not significant, especially if it is early on in pregnancy. a loss is a loss, and we need to give people the time and space to talk about that, process the trauma of their loss, and to really come to terms with what they have gone through. so, the best thing you can do is to open up the subject, and then listen. you do not need to say anything other than "i'm here and i want to listen to you tell your story." and how much difference does it make that this is the prime minister's wife and we know that other significant public figures have also shared their own experiences of deep pain? does that make an impact for other people across the country? it certainly does. we see a massive influx of people asking for support if anybody of note, or even a tv show covers the story of baby loss

in their shows, we see real influx of people. i think itjust means to a lot of people that it is ok to talk about this subject. sadly, for generations, people have been told not to talk about loss, to not talk about miscarriage, especially when you are told don't tell anybody you are pregnant until after 12 weeks just in case you go through loss. it just reinforces that message of staying silent. so when people of note and people in the public eye talk about their own personal losses, i think it gives, generally, a lot of people the confidence to start speaking about it and sharing about their own stories. what has been the impact on other generations of not talking? well, i think the compounding of grief, i think we see a lot of people, as an organisation, who seek support, who have lost babies 20, 30, 40 years ago, who have never had the opportunity to talk. for a lot of people,

it has affected marriages, it has affected their lives going forward. there is a statistic that around 70% of relationships broke down after going through baby loss. so much of that is down to people not being able to access the support when they need it, couples not being able to process that loss, and sometimes that can mean a breakdown in relationships. so, great support offered immediately after a loss is really vital. you talk about support. are there sufficient resources out there for couples who need time off work, who might need counselling? well, like you say, is there enough support? i think for many people they will say no. there's over 258,000 losses every single year, just in the uk, and that's a lot of grieving people. the support that is available is great, i know from us as an organisation, our support reaches over 50,000 a week,

but that shows you the scale that people are trying to access that support. there are as many people who don't speak out. like you mention, people do not get time off work when they go through a baby loss. sadly, bereavement leave is not extended to those who have an early miscarriage. it is only extended to those who have a loss over 24 weeks. for many people, they are forced to go back to work before they have even had a chance to come to terms with what they have gone through. american military forces have boarded an israeli—operated oil tanker after two crew members — from the uk and from romania — were killed in a reported drone strike. the us navy has said experts boarded the tanker to "ensure there is no additional danger to the crew, and are prepared to support an investigation into the attack". israel has accused iran of being behind the attack, which took place off the coast of oman in the arabian sea on thursday. iran has not yet responded to the allegations, but it appears to be a serious escalation in tensions in the region.

our middle east correspondent, tom bateman, has more from jerusalem. the foreign minister, yair lapid, who has quite firmly put this at the feet of the iranians and said that he had spoken to the uk foreign secretary, dominic raab, about this because one of the two people killed on board was a british security guard on the ship. the other was a senior member of the crew, a romanian national. now, mr lapid said that he expected the need for what he described as a "severe response" following that attack. that was in a phone call to that uk official, to mr raab on friday night, and in terms of the details we have now about this attack, as you say, us navy fifth fleet explosive experts have been on board and the maritime security industry is saying that they understand this to be a drone attack by a so—called attack drone. now, these are explosive—laden drones that are flown by remote control into objects, and it's believed this was flown

directly into the bridge of this ship and that's when the fatalities occurred. so, there is an investigation going on. the ship is continuing north past muscat at the moment under its own power, officials say, but it is under us naval escort, but what this does is to really ramp up tensions into what is often seen as a shadow war between the iranians and the israelis across parts of the middle east. but this, in terms of what happens at sea, as far as those confrontations are concerned, marks a serious escalation. tom bateman in jerusalem. fire—fighting planes from russia, ukraine and azerbaijan have been helping turkey to put out wildfires raging along its southern coast. at least four people have died and dozens have been taken to hospital. the flames have also forced the evacuation of entire villages. president erdogan has declared the areas affected by the fires as disaster zones. esra yalcinalp of the bbc�*s turkish service has more on what he's been saying.

that means about £4.2 million of funding will be available to those areas for the rescue efforts and for the recovery efforts. on top of that, there will be interest—free loan opportunities and they will be starting to rebuild the houses in one month, and they promised to finish them in about one year. it has been a tremendous effort from the fire fighters on land and also in air. this has been the largest scale of fires at the same time that the country has seen. there are just too many fires going on at the same time. according to the ministry, it's100 fires in 24 cities in the last four days, and there are even more fires occurring as we speak. for example, another place was added to the list today.

the weather is dry, the wind is strong, the heat is high so the weather conditions are not really helping. and the areas are mountainous, covered with pine trees, which are full of pine cones, and when the pine cones go up in flames they explode from the tree and create small fires in the territory, so the firefighters are having difficulty on land, so the helicopters are helping from above and russia, azerbaijan and ukraine have sent their planes to help with the efforts. volunteers are coming from different cities, trying to put out with the water they have brought with them the small fires they see on the ground, so there is a collective effort. everybody is trying to do their best, but itjust has not been enough. the uk telecommunications 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 correspondent, jonathan 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 forflexibility. it is the sector's first fully reprogrammable spacecraft. it's 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 in to help people in places hit by catastrophic floods or earthquakes. quantum's manufacturers in the uk — that's 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. jonathan amos, bbc news. now it's time for a look at the weather with louise. it has been a largely cloudy saturday across the country, but there have been a few listens showers around central and southern wales, central and southern england. these showers will fade away as we go through the evening

and overnight and into tomorrow we could continue to see the threat of showers as this week weather front dawdles its way steadily southwards. behind it, coolair, no small difference to the feel of the weather in comparison to northern ireland and northern england but it will be largely fine and dry here showers more heavy under the south of the m4 corridor. 21 degrees here but only 12—17 further north. it looks likely that it will be a relatively quiet start once we lose early morning rain into the south—east.

hello, this is bbc news. i'm james reynolds. the headlines: super saturday comes round again. kicked off with a gold, and a world record in the 4—by—100 metres mixed medley final.

and continued in the triathlon mixed relay event —
