4:02 pm
hour — the media show. good afternoon and welcome to bbc news. adding two more gold medals to their tally — in new events involving both men and women. the first came in the triathlon mixed relay. then, in the swimming pool, great britain claimed another in the mixed 4—by—100 metre medley. in athletics — jamaica secured a clean sweep — first, second and third in the women's 100 metres. elaine thompson—herah stretched into the lead to take the gold medal in an olympic record time of 10.61 seconds. it comes as one of team gb�*s great medal hopes — dina asher—smith — saw her bid for the podium come to an early end,
4:03 pm
afterfailing to qualify for the 100 metre final. she says she's still struggling with a hamstring issue and has now withdrawn from the 200 metre event. so where does that leave the medals table? team gb remain sixth — they have picked up eight gold medals and 28 in total. at the top is china — with 21 golds and 46 overall. for a full round—up of the action let's cross to austin halewood at the bbc sport centre. what a final of the women's 100 metres it was. jamaica's elaine thompson—herah ran the second fastest time in history to succesfully defend her 0lympic100 metres title. she beat her compatriot
4:04 pm
shelley—anne fraser—pryce — with a time of 10.61 — the second fastest time in history, just 12—hundredths of a seconds short of the world record set 33 years ago by american florence griffith—joyner. shericka jackson completed a jamaican one—two—three in tokyo. britain's daryll neita finished eighth in the final. there were great hopes for britain's dina asher—smith in the 100 metres. but she failed to reach the final after revealing that she'd been struggling with a hamstring injury. she's even had to pull out of her stronger event, the 200—metres. and she was understandably emotional, as she explained her decision. i am going to pull out. john just had that conversation with me, and that's the one that... as reigning world champion, you just... and i was in such good shape. you just know that the olympic champion is not too much of a further step. i'm really proud to have been able
4:05 pm
to execute my races here today, really proud everything i have done to this point. but when you're talking about the standard that i want to be at and i know i am capable of, sometimes if you... there's plenty more championships for me to come and kill. and in the men's100 metres heats, european champion zharnel hughes ran a season's—best time of 10.04, to reach the semi—finals along with team—mates cj ujah and reece prescod. but away from the athletics, it was a golden saturday for team gb in tokyo. it was a day when team work has been the key to success. firstly, in the new triathlon relay, and then 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 tokyo today
4:06 pm
it was teamwork that triumphed. super saturday had barely begun, but team gb was already looking at four new 0lympic 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 0lympic race, a last chance to complete the set. georgia taylor—brown had given britain a 21—second 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.
4:07 pm
now a moment for the team's finest to come together. the mixed medley relay, another new 0lympic 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 can build everything around that. two team relays, two olympic team titles — another golden day for team gb. emma wilson took windsurfing bronze on her 0lympic debut. she was already guaranteed a medal going into the final, after winning four of her 12 races, and she crossed the finish
4:08 pm
line in second place — but with cumulative scores counting, that gave her bronze, behind china's lu yunxiu and the rio champion, charline picon of france. and in the women's hockey — great britain completed their pool matches with a 2—0 victory over ireland at the hockey stadium. the reigning 0lympic champions had already secured a place in monday's quarterfinals. goals from susannah townsend and hannah martin confirmed their third—placed finish in pool a behind group winners holland and runners—up germany. ireland, though, are out of the competition. the last eight completed by india, australia, spain, argentina and new zealand. 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.
4:09 pm
well, our reporter, eleanor roper, is at the lee valley athletics centre in north london to get reaction to dina asher—smith's disappointing news. not what she wanted or anyone expected. we have been watching here on the big screen, really exciting. desiree henry is here, she raced with dina at rio. give us your reaction. i'm kind of shocked, but i made this prediction yesterday when i said people should not count out elaine thompson—herah, she is the previous olympic champion. that does not come lightly. i am just shocked at how she did it, and at the time, 10.61 is absolutely incredible. she did it in class and style. you did call it. ijust cannot believe it. but we all hope and want our favourites to win, but for them to go out and do it it is a whole other ball game. also, it was a jamaican one, two,
4:10 pm
three, which i expected but did not expect it to see it live. hugely disappointing for dina asher—smith, but daryll neita made it through to the final? i feel for daryll, this is still an amazing thing to be celebrated. she made an olympic final. yes, it may not have been the performance that she wanted, but she should still be able to hold her head up high. congrats to daryll also. huge disappointment for dina asher—smith, she has been struggling with a hamstring injury, she has also pulled out of the 200. can you just talk us through how disappointing that will be for her? this will be extremely disappointing. you know, the fact that she came down to the olympics and try to compete in every single round possible, you knew that her mind frame was, "let's see what my body can do and if it can hold up."
4:11 pm
unfortunately, it was not the case and i am just extremely sad for her because i know she was on a quest of coming back with olympic medals in multiple events and it has not worked out. all she can do is keep your head up, the world championships are next year, there are so many championship. this is not the end for her. definitely not, showing her class again today, very quick to congratulate her team—mate on that 100 metres final. next up we have the men's. in the past few minutes, the prime minister's wife, carriejohnson, has announced she is pregnant. they have a son, wilfred, who was born in april last year and was seen at the g7 summit in cornwall injune. 0ur political correspondent, nick eardley, is here with me now.
4:12 pm
what do we know? just in the last half—hour, carriejohnson has posted on instagram that she is expecting around christmas. she and boris johnson were married in may and that fairly small and too good to have ceremony at westminster cathedral. now they are expecting their second child around christmas time. it is pretty rare for a prime minister as to how children while in office. i think there has only been four in the last 150 years or so, so it is quite a rare thing. in this post carriejohnson has put up on instagram, she has also reviewed that she had a miscarriage at the start of this year. i want to read you a particular point of it which she has put up, saying "i feel incredibly blessed to be pregnant again, but i also felt like a bag of nerves. fertility issues can be very
4:13 pm
hard for people, particularly when on platforms like instagram it looks like everything is only ever going well. ifound it a real comfort to hearfrom people well. ifound it a real comfort to hear from people who also experienced lost, so i hope that in some very small weight shedding this might help others too.". happy news for the prime minister and his wife, but also some sadness in that post as well. carriejohnson and says that she hopes by sharing her own experience, it might help others. the latest figures on coronavirus. the latest figures on coronavirus. the daily cases have been reported at 26,144. 71 people have sadly died, that is of the deaths of the pot testing positive within 28 days.
4:14 pm
927 people have been admitted into hospital. quite a big push taking place the days to get the young to sign up and get the jab. in terms of the first days, that has been reported at 46.8 million, that is the total that have received the first dose. the total number of adults in the uk who have had both dosesis adults in the uk who have had both doses is now an 72.1%. 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 healthcare professionals before using the devices and not
4:15 pm
to rely on a single reading. the director of the nhs race and health 0bservatory, dr habib naqvi, says concerns about oximeters�* reliability have been mounting. 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
4:16 pm
decision—making, so we need to get this right. earlier i spoke to dr 0lamide dada — one of the authors of the report. i asked her how widespread this issue was. when we're considering the use of these devices, how widely accessible they are to patients and how frequently they are used in clinical environments, in hospitals and gps, it is really important that both patients, members of the public and clinicians are aware that the readings can be less accurate in darker skinned patients. which way are the results skewed, lower or higher? the devices are actually likely to overestimate oxygen saturations, particularly in black patients, as well as other ethnic minority groups. a particular study conducted in america found that black patients
4:17 pm
were three times more likely to have that oxygen saturations reading overestimated in comparison to white patients. there was a report that was conducted at the end of 2020, in america, and this was highlighted, because a lot of people have these oximeters at home to monitor themselves if they have contracted covid—19. however, there was also a report back in 2007 a report back in 2007 that highlighted the issue with people with darker skin. why has this not been picked up, changed, fixed? that's a question for all of us. we're hoping that as the pandemic has shone a light on inequalities, as well as disproportionate impact on ethnic minority groups, it is very possible that oximeter might have contributed to that outcome. even though it was mentioned a few years ago, the most recent study had a larger population that was studied, further supporting the fact that these devices are likely to oversetimate the readings
4:18 pm
in darker skinned patients. when we consider the impact of this, this can contribute whether or not people come into hospital, how soon they come into hospital, what care is provided when they do come into hospital. the fact that if your oxygen readings are overestimated, that means you are likely to have a lower reading, are you receiving the oxygen that is necessary to adequately treat the patient at that time? if these patients are admitted to intensive care units, are they receiving the treatment that they require? of course this can have a significant impact on health outcomes. fortunately the pandemic has provided a suitable opening to further explore this area. the headlines on bbc news: )elaine thompson—herah ofjamaica has won the women's 100 metre final at the tokyo games — in a new 0lympic record
4:19 pm
time of 10.61 seconds. medical experts are warning that an oxygen monitoring device, called an 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. an investigation has been launched after the body of a five—year—old boy was recovered from a river, in south wales. officers were called to the scene near pandy park in the village of sam, near bridgend at 5:45 this morning. police have appealed for information from anyone who was in the area at the time. afghan security forces are battling to defend three key cities from advances by the taliban. reports from herat, in western afghanistan, said the militants had broken through front lines — but a local official said government forces were moving cautiously to try to avoid civilian casualties.
4:20 pm
fighting is also continuing in kandahar and lashkar gah in the south. hundreds of people are reported to be fleeing their homes. secunder kermani has just sent this update from kabul. fighting is taking place in and around a number of afghan cities. in lashkar gah, in the southern province of helmand, taliban forces came within one kilometre of the governor's office right in the centre of the city yesterday before being pushed back. the afghan army commander there saying his troops managed to inflict a high number of casualties on the militants, but we understand they remain at the mostjust a few kilometres away from the city centre. today in lashkar gah a hospital was badly damaged by government air strikes targeting taliban fighters in the area. i'm told at least one security guard was killed and two doctors injured, though initial reports suggested that patients being treated at the hospital had already been evacuated. in the west of the country, in the city of herat, fighting is ongoing for the third day after government forces
4:21 pm
managed to recapture the area around the airport, which had been briefly taken by the taliban. government forces there supported overnight by us air strikes and by militia forces led by a powerful veteran commander now in his 70s. it seems pretty clear that the taliban having already captured large amounts of rural territory in afghanistan are now really turning their focus to the country's cities. they haven't yet managed to capture one, but this fighting is of course displacing tens of thousands of people. many other afghans are planning, or at least considering, their options to leave the country. many people fear that come the end of august and the formal end of international military mission in afghanistan, the violence is only going to get even worse. 0ur 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
4:22 pm
is one where the taliban offensive is held back. where there is a bit of push back, a bit of rebalance. all these nice words that still mean further suffering and deaths, a larger number of afghans dying on both sides. more people on the run, leaving their homes. but 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. bbc news has been told that the government is no longer considering making it compulsory for students to be fully vaccinated against coronavirus to attend lectures in england. ministers had previously refused to rule out a requirement to be double—jabbed on university campuses, and said the decision would be taken in september.
4:23 pm
0ur political correspondent, pete saull, says this comes in the context of the controversial decision to consider so called vaccine passports in other areas. from the end of september, if you want into a nightclub, it will be a question of if you're notjabbed, or double—jabbed, you're not coming in. but ministers have been floating other settings where that might be the case. opening up international travel for people who have had both jabs. the idea was that once university students return from their summer break in the autumn, they will have to have both jabs to go to lectures or even stay in halls of residence. that was something they were looking at but i do understand that particular proposal has been shelved. meanwhile conversations about other things, premier league football, for example, continues. why did they go back
4:24 pm
on that proposal then? i think there were two key reasons. the first being logistics, how could universities police this? there were legal questions as well. when you get an offer of an university place, that is considered to be legally binding. i think ministers are also aware that unease is growing on conservative backbenches about this wider issue of vaccine passports. jacob rees—mogg last night said it would not be the end of the world to have to show proof of vaccination to gain entry to venues, but he also said we should protect our ancient freedoms. i think that sentiment about freedom is one shared very widely across the conservative party, and i sense a lot of people out there might be uneasy about having to show papers to get into anywhere, whether it be the pub, nightclub, restaurants, whatever. i think the government now feeling the heat on this issue and might ultimately decide the use of vaccine passports might not be as widespread as it was a couple of months ago.
4:25 pm
have they laid an alternative to the return to university for students? not specifically. initially, they said that this would not be about covid certification in september. testing will clearly play a part of the mix as well. it is hoped by that stage, case numbers will be down and hopefully things will start to return to normal. fire—fighting planes from russia, ukraine and azerbaijan are 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 says as well as planes, helicopters, drones and 1000 vehicles are involved in the firefighting efforts. translation: unfortunately, 71 wildfires have broken out. l 57 forest fires were contained.
4:26 pm
efforts are underway to contain 14 wildfires so there is a progress in a positive direction. more than 100 motorists have had to be rescued from a mountain canyon in colorado after a landslide swept across an interstate highway. around 75 people had to spend the night in their vehicles as emergency crews cut a path through the mud and debris to reach them. remarkably, there were no injuries. officials say heavy rain sent a torrent of mud and rocks cascading down slopes stripped bare by a wildfire last year. but they're doing everything possible to get the highway open again. we are sending a large number of tandem dumptrucks, bucket loaders, vat trucks, to clean out drain systems, drainage systems. we are also sending additional radios, we are trying to beef up on a temporary basis our cellular communication networks within the glenwood canyon area. so, it is all hands on deck. the uk telecommunications industry
4:27 pm
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 for flexibility.
4:28 pm
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. jonathan amos, bbc news. now it's time for a look at the weather with louise lear. good afternoon. it is sunny spells and scattered showers for many of us for the remainder of the afternoon. let's take a look at what has been happening. quite a lot of cloud, generally, across the country. showers have been sitting through eastern scotland and north—east england and more widespread showers through central and southern wales down into central
4:29 pm
and southern england as well. here, the odd rumble of thunder but with some sunshine we could see temperatures peaking at 21 celsius, a little bit cooler further north. and that cooler air is set to descend steadily south. behind it, this cold front. that is going to continue to enhance some showers for sunday across southern parts of england, in particular. some of those showers, as the isobars open up, the winds fall lighter, and they could be heavy and slow moving, still with the odd rumble of thunder. so, that is going to be an issue across central and southern england. behind it, sunny spells, fewer showers, but not as warm as it has been of late. top temperatures, 12 to 21 degrees. hello this is bbc news. the headlines... it's known as super saturday and there was a great start for team gb in the tokyo olympics, with a gold and a world record in the 4x100 metres
