welcome to our viewers on pbs in america and around the globe. 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. earlier, i spoke to our north america correspondent david willis, and asked him what had brought us to this point. well, you're absolutely right, rich — every president in modern times since richard nixon has declared their tax results. the only exception to that being donald trump, of course, and he has fought tooth and nail to keep those documents secret and he had the backing —

up until recently, of course — of the usjustice department. well now, there's been a change of the guard, if you like, there. there is a biden administration in place. new officials are occupying senior positions in the us justice department and they have decided that it is legitimate for the house ways and means committee to seek donald trump's tax returns, so they've ordered the us treasury to make them available. now, this could be the beginning of the end of a very long, drawn—out process involving the former president and his claim — or his aim, i should say — that these documents should be kept secret and out of the public eye. david, has there been any response from donald trump or from the trump organization? not so far, rich, although what we are hearing is that democrats are, of course, very pleased with this.

they have welcomed this move. the house speaker nancy pelosi saying that access to the tax returns of donald trump was a matter of national security, as she put it, because it would shine light on what she called donald trump's "troubling conflicts of interest". republicans, though, have denounced this move by the usjustice department. they've called it "politically motivated" and say that it could lead to open season on the tax returns of future political candidates. david willis in la. the israeli foreign minister yair lapid has called for a harsh response after two crew members were killed in an attack on an israeli—operated oil tanker in the arabian sea near oman. the vessel's owners, zodiac maritime, says one of those killed was british and the other romanian. iran is suspected of being behind the attacks. here's the bbc security correspondent frank gardner. well, this is quite a serious escalation and it certainly

doesn't look like piracy. an investigation was begun fairly soon afterwards. it took place late in the afternoon yesterday about 150 nautical miles — that's about 250, roughly, kilometres — north—east of the omani port of duqm, and what israeli television is saying, quoting an israeli official, was that it was attacked by an explosive drone. now, usually in piracy attacks, it's very unusual for anybody to be killed. piracy attacks are quite rare now because most of the ships either have escorts or they've armed guards on board, so they are nothing like the level that they were at ten years ago, so the suspicion is that this is some kind of state—backed terrorism, and certainly the israeli media is pointing the fingers at iran — there is no immediate word from iran — and in the past, iran has denied any part in such attacks. the ship itself was carrying no cargo. it was on the way from the port

in dar es salaam in tanzania going to the port of fujairah in the united arab emirates, and it has been escorted for the last leg of its journey by the us navy. there is no question that there is an undeclared shadow war taking place between iran and israel where they had been attacking each other�*s interests. in the case of israel, they had made no secret of the fact that they are trying to slow down iran's nuclear programme and although they have never admitted it openly, they have certainly hinted that they have played a part in the sabotage attacks, for example, on some of the nuclear facilities. but offshore in the red sea, the arabian sea, the northern indian ocean, there have been a number of mysterious explosions on board ships. iran, for example, has a fairly stationary ship that's at the bottom of the red sea — that had some explosions on board — and there has been israeli ships that have come under attack as well. so it's this undeclared shadow war where the two countries have very been carefully calibrating what they do, not to cause too much pain but enough to keep the other one — make the other

one uncomfortable. more than 1,600 pregnant women have died in brazil since the beginning of the pandemic. the bbc has obtained exclusive footage from the only intensive care unit for pregnant women with covid—i9 in sao paulo. bbc brasil�*s nathalia passarinho reports. sings along with music. 23—year—old laryssa has always dreamt of being a mother. just a year ago, she was 35 weeks pregnant with twin boys. translation: we started thinking of names, in casei we had boys or girls. we thought about clothes and the crib. since the beginning, we started to plan everything. but her dream was taken away too soon. after being diagnosed with covid—i9, she was admitted to an icu in sao paulo. shortly after an emergency c—section, she died

of a cardiac arrest. i saw the babies, i saw what true love is. but when i received the news, it was so difficult. how could my whole world fall apart in a matter of hours? laryssa is one of more than 1,000 pregnant women who have died from covid in brazil this year. neonatal wards in the country have been filled with premature babies. deaths among pregnant women were high even before covid spread in brazil, mostly because of a lack of adequate specialist care, but the pandemic really made things worse. dr rossana pulcineli in the intensive care unit she helped open in the city of sao paulo. it is the only unit in the country dedicated to pregnant women with covid. why are so many pregnant women dying of covid in brazil? translation: we have

serious problems with l the quality of assistance. one in five women that died did not have access to an intensive care unit. one in three didn't have access to intubation. the unit helped bring mortality rates down in the city, but in the poorer parts of brazil, access to even a hospital bed remains a challenge. in a remote village in north—eastern brazil, expedito�*s wife aline was only 27 weeks pregnant when she was diagnosed with covid. she had to be driven for two hours to reach a hospital bed. she died a few days later. her babies were born on the same day. translation: for me, it was a big shock. - i fell down to my knees near the doctor's feet. i couldn't believe it. do you believe there is something that could have

been done differently to save aline's life? i wish i had taken the vaccine for covid. brazil has the second—highest number of covid—related deaths worldwide, yet only over 16% of the population have been fully vaccinated so far. and until the pandemic is brought under control in brazil, thousands of pregnant women will remain at risk. nathalia passarinho, bbc news. sticking with covid—19 for the time being. a new covid outbreak centred on the city of nanjing in eastern china has been called the country's worst outbreak since wuhan in march 2020. state media say it's the most extensive outbreak since wuhan. 200 people have been infected since it was first detected at the city's busiest airport. all flights from nanjing airport will be suspended for the next fortnight. well, iam nowjoined by associate professor

of public health at yale university and nanjing native dr xi chen to discuss how china tackles this fresh crisis. doctor chen, thank you for making the time for us. how do the outbreak begin?— the outbreak begin? think you for having _ the outbreak begin? think you for having me. _ the outbreak begin? think you for having me. overall- the outbreak begin? think you for having me. overall china i for having me. overall china has so far managed to keep the virus largely under control, as we know, by closing the orders and moving quickly to stamp out local breaks but this time, nanjing authorities were slow in their identification of the virus and it was transmitted from an air flight from russia through air china air flight to nanjing onjuly ten but after ten days, the first identifying case of positive covid—19 infection was coming up so it took around ten days which was longer than usual, and it took another ten days for the authorities to trace the origin of this transmission, which was from the russian flight. so to

take another ten days, i think this timing, delayed timing, is really the key that of course a large—scale —— has caused a large—scale —— has caused a large scale of spreading, and as you mentioned five provinces but now it is eight provinces so it's a faster developing around 22 cities involved and more than 200 cases identified. this is an outbreak of the delta variant. you mentioned local authorities have been slow to act. what have they done? are there lockdown enforced? are people being told to stay at home?— to stay at home? indeed, the cities are _ to stay at home? indeed, the cities are under— to stay at home? indeed, the cities are under lockdown - to stay at home? indeed, the cities are under lockdown ori cities are under lockdown or semi lockdown and not only for nanjing but all of the links, the traces destination from nanjing, iwas the traces destination from nanjing, i was mentioning like eight provinces, 22 cities, have all kinds of different lockdowns based on their situations and so far, most of the cases already have been traced the origin of the virus outbreak, which is good. it

means it is still the early stages but there are still a few cases in some provinces and some sources are unknown so it is not clearly linked to nanjing so this is worse so they have to be there click on contact tracing and the tracing of the sources in order to stamp out the local outbreaks and we all know this is so far the worst outbreak since wuhan. briefly, do we know much about vaccine rollouts in the areas affected and how the virus is going to fair with that? in general, china has a very vaccination rate —— fare. it's slowing down but it's still very high in some areas around 80% of people vaccinated. it varies a little bit but given this is a new variant, the immunity will be changing so even by the end of this year

the chinese authorities are aiming for about 70% — 80% of people vaccinated so farjust ten days ago, they reached 1.4 billion doses being vaccinated so does make but given the new delta variant, it will take an even higher number and proportion of people to be vaccinated to fight against this delta variant.- this delta variant. doctor chen, thank _ this delta variant. doctor chen, thank you - this delta variant. doctor chen, thank you very - this delta variant. doctor l chen, thank you very much this delta variant. doctor - chen, thank you very much for joining us. chen, thank you very much for joining un— stay with us on bbc news. still to come: more from the olympics in tokyo, where it's super saturday. plenty of action ahead, including the women's 100 metres final. cheering. the us space agency nasa has ordered an investigation

handed to congress, after a ruling by the us justice department. and more than 1,600 pregnant women have died in brazil since the start of the pandemic. 200 afghan interpreters and their families have landed in the usa, the first as part of a planned evacuation programme. presidentjoe biden says the us is fulfilling its promise to those who served "shoulder—to—shoulder" with american forces in afghanistan. our correspondent secunder kermani reports from kabul. tens of thousands of british soldiers served in afghanistan. crucial to their mission, the help of local interpreters. with international troops withdrawing, hundreds of them, along with their families, are being relocated to the uk. but others remain stuck in afghanistan. this man is one of dozens of interpreters whose applications have been rejected. he says he fears for his life.

they're going to kill me. that's it. it's a big threat for my family also. because of me, my family will pay for that. he served with british forces for two years in helmand province, but was then sacked. those dismissed for serious offences aren't being relocated. he says he simply refused to go on a second consecutive mission, in order to attend his engagement ceremony. defence sources alleged he repeatedly failed to turn up to work. i was very sad. i wrote all my story, what happened to me in helmand, because i did a good service. so, i thought that maybe i would receive a positive response. afghan forces pushed back a taliban advance towards herat city. the insurgents have not taken any provincial capital yet, but some fear it is only a matter of time. the taliban say former interpreters who worked with foreign forces but now "show remorse" will not be harmed.

few are reassured by that, though. dozens are reported to have been killed by the group in recent years. military veterans and campaigners say the evacuation policies need to be more generous. the absolute priority for afghan relocation and assistance policy is looking at, are these people under threat because of their association with us? and the only exception that needs to be made there is that if there would be any individuals who would be posing a risk to the national security of the uk, then it would be a basis for exclusion. with fresh taliban assaults every day, britain's ministry of defence says it has already relocated more than 2000 former local staff and that its scheme is one of the most inclusive in the world. everyone knows the situation is growing increasingly critical. secunder kermani, bbc news, kabul. let's get some of the day's other news. food supplies destined

it did make its debut and it was a gold medalfor team gb, that race finishing up just a little earlier, alex yee bringing it home for the brit in a phenomenal race. triathlon is on course renowned for being this ultimate test of individual endurance, you have three disciplines to master, this was a little more fast—paced than usual because it was a teams event so two men, two women lining up in the race and each member was doing a 300 metres swim, a 6.8 kilometre run —— ride and finishing off with a two kilometre run, i am tired just watching them, i don't quite understand how they do it, but team gb making history there in that inaugural event for the olympics. rounding out the medals were the usa in silver and france in bronze. incredible endurance, but the athletics are the mainstay of the weekend, aren't they? the

heats are _ the weekend, aren't they? the heats are under _ the weekend, aren't they? tue: heats are under way, the weekend, aren't they? tte: heats are under way, plenty of action throughout the day. later, all eyes will be on the women's100 metres sprint final which is a classic event of the olympic games, we have the semifinals to watch first, we are expecting some incredibly fast racing based on the times of those heats and potentially history to be made in the final as well, jamaica's shelly—ann fraser—pryce is looking to become the first woman in history to win three olympic athletics events. so she has won the 100 metres sprint twice before, she is looking for that third gold medal, we will see if she can do it or not. team gb's dina asher—smith will be hoping to — those hopes, what we do know though, one woman who won't be lining up in those race is nigerian blessing okagbare who hasjust race is nigerian blessing okagbare who has just been announced to be suspended following a drugs test. she failed back the athletics integrity unit says that 32—year—old had tested positive for hgh, that was following and

played to an empty royal albert hall. mark savage reports. i will now try and take you over to door one, it has been two years since i've done this so i might get lost. it is notjust the stewards — for music lovers at the royal albert hall, the wait is over. finally, i am absolutely thrilled, i have been waiting two years for this day. being not socially distanced will be something to quickly get over. to be leaning forward, listening to music with the same intensity as the person next to you is going to be just, it is a feeling of community. the concert was led by finnish conductor dalia stasevska with the bbc symphony orchestra socially distanced on a specially extended stage. how strict are they? we have a guy with a ruler. laughs. what is it like to be back? we have been waiting over a year to have a full audience and i think that we are all emotional and we are going

to play really our hearts out with this concert. what is the moment of the concert you're most looking forward to? just to hear the people clapping and the whole ritual, just to start the silence and the waiting, when the first note starts to play. music plays. and the opening piece of music, by vaughan williams, held a special significance. really the whole night is about new beginnings and celebrating together. # rule britannia, britannia rules the waves...# last year's proms ended on a controversial note after the bbc announced and then reversed a decision not to sing the lyrics of rule britannia. i have kind of moved forward from all of that, and what i really want to say is that i am extremely proud that the whole last night actually came together at all.

this year's opening night drew a line under the controversy with a programme that was simultaneously reflective and hopeful. and when it's all over, how are you going to feel? i think that after the journey that we have made from doing this one and a half years and that we finish the concert and we have the audiences there, i think it will feel like a great victory. classical music, dalia says, has a healing quality, something that has never been so important. mark savage, bbc news. a word of warning, if you are scared of heights, look away now. as if this glass—bottomed

suspension bridge in china's hunan province wasn't terrifying enough — it now is offering the world's highest bungyjump from a footbridge. visitors can take in the views as they leap from the nearly 900 foot drop. the jump comes at the hefty price of around $300 but gives plenty of bragging rights to those willing to brave the fall. and i would definitely not one of them. just before we go, let's take a look at some new pictures from mexico, where guadalajara zoo is celebrating the safe arrival of its latest family member. this baby hippopotamus — whose sex is still unknown — is in good health, and currently weighs around 50 kilograms. hippos are nocturnal animals, usually preferring to rest during the day — but while their offspring are young, just like human parents, they spend a lot more time awake. so the doting mother and father have been seen up and about and much more active than normal recently. a reminder of our top story: the usjustice department says tax returns belonging to the former president,

donald trump must be handed over to congress. you can reach me on twitter — i'm @ rich preston well, friday brought quite a nasty spell of weather to some south—western and southern areas of the uk. gale—force winds around coasts briefly. they were very, very strong indeed, brought by storm evert. you can see on the satellite picture here thunderstorms and heavy showers inland, generally a really changeable day, but the weather has now shifted into the southern north sea. it's approaching parts of germany and denmark. behind it, you can see from the motion of the arrows, it's a fairly cool north—northwesterly, so it's going to be a fairly cool day for most of us. really quite nippy, in fact, in the very far north of the country. sunny spells and showers expected. so, let's have a look at the early morning hours. that northerly wind blowing across scotland and along the north sea coast.

showers there right from the word go, but i think showers are possible almost anywhere early in the morning, apart from the extreme north west of the country here. temperatures a little on the fresh side, around 12—13 degrees in some spots. and then, tomorrow, a pretty cloudy day for many of us, in the morning at least, to start with. then the sunny spells develop, but also the showers, and some of them will be heavy. you can see here in the east of the country and the north, some thunderstorms there, too. showers also breaking out across the south. the best of the weather, i suspect, in the north—west of the country, parts of northern ireland, south—western and western scotland and also cornwall, devon and southern wales shouldn't do too bad on saturday. here's a look at sunday's weather map. the weather still coming in from the north. we have a weather front crossing the country. that is expected to bring showers to more southern areas of the uk on sunday. they should be more confined towards the very far south towards the end of the day. that's how the end of the day

starts, so a little on the chilly side in some areas. those northerly winds, feels quite nippy along the north sea coast, could even be around 14—15 degrees during the daytime. best spots, i think, in southern wales, maybe northern ireland again, but i think in southern wales and cardiff, up to around 21 degrees or so. so, here's the weekend summary again, and the outlook into next week, not an awful lot changes. there's no warm weather on the way. i think it's going to stay more or less the same, below average and a chance of some showers. and that's it, bye—bye.

this is bbc news, the headlines: the usjustice department has ruled that the tax returns of former president donald trump must be handed over to a congressional committee. unlike other recent presidents, mr trump had resisted the demand that he surrender his tax records, and the justice department had backed him while he was in office. covid—19 has critically affected pregnant women in brazil, with more than 16 hundred deaths. one in five women that died from the virus didn't have access to an intensive care unit and one in three didn't have access to a ventilator. president erdogan of turkey says fire—fighting planes from russia, ukraine and azerbaijan are now battling the wildfires on the country's southern coast. at least four people have died and dozens have been taken to hospital. officials have promised to bring anyone responsible
