welcome to bbc news — i'm david eades — our top stories. president biden holds firm on his afghan withdrawal deadline — he tells g7 leaders any delay increases the threat of violent attacks. each day of operation brings added risk to our troops, but the completion by august 31 depends upon the taliban continuing to cooperate. in kabul — continued desperation at the airport as the taliban now say no more afghans will be allowed there. also in the programme — a crucial court ruling expected in brazil that could have a dramatic impact on both lives and landscape. and — tributes

to the rolling stones drummer — charlie watts — who's died at the age of 80. for all the urging and cajoling from fellow world leaders, it seems the president is not for turning. joe biden has made clear that he intends to stick to next tuesday's deadline for the us to complete its evacuation mission in afghanistan. in a televised address from the white house, he said the longer american troops remained at kabul airport, the greater the risk of an attack by a terror group known as isis—k. the taliban has also made it clear that it's not prepared to give foreign forces any more time on afghan soil. here's what mr biden had to say. we are currently on a pace to finish by august the 31st. the sooner we can

finish, the better. each day of operations brings added risk to our troops, but the completion by august 31 depends upon the taliban continuing to cooperate and allow access to the airport to those who are transported out and no disruptions to our operations. the world bank says it's suspending aid to afghanistan because of the taliban's seizure of power. the bank says it's deeply concerned at the impact ths will have on development projects, especially those benefiting women, and that it would closely monitor the situation. the situation on the ground remains fluid and chaotic. the taliban was reportedly stopping afghans from getting to the airport area — and foreigners could only get their people out — not afghans. our chief international correspondent lyse doucet has sent this from kabul airport. her report contains some distressing images "stay calm," orders this taliban guard.

there's no calm here. not in a crowd too big to count, too big to control. but the days are numbered now before the us pulls its soldiers from this airfield, before their last evacuation flight lifts off. panic is rising. most afghans have waited here for days, including four—year—old twins usna and usnia. their father was a guard for the us military. they've got documents to prove it. "it's been such a bad experience," their mother says. "so bad — my children have been so scared." "we are meant to leave." you can feel the fear — it's notjust the kids. wahida faizi, an afghan journalist, believes she's not safe under taliban rule. they know i'm a journalist. if they know, i know

they will kill me. one day you will come back to afghanistan? never. it's not my country. after this, it's not my country. gunshot. these are the last moments for afghans who feel not only are they leaving their country, they're losing it, leaving everything behind. this is a journey like no other. the most importantjourney they're probably going to make in their lives. and it's a journey so fraught with risk and fear. wahida faizi, in her red headscarf, keeps pushing forward. on this side, british soldiers glance at papers. they stand guard — doing whatever they can to contain the chaos along with us troops. translation: these americans are inexperienced. _ they asked the people to come

in a very short time. they made this rush of people. this is the mismanagement of the americans, and nothing else. and at a taliban news conference today, an even starker message. translation: my message to the americans is that - they should evacuate all their citizens by the deadline of august 315t. they have the resources, they have planes, they have the airport. they should evacuate all their forces and their contractors and those belonging to them. we will no longer allow them to evacuate afghans. in the centre of this city, behind another gate, another place of hardship and heartache — families displaced by fighting. they're on the move, too. now that the taliban have taken control, they're boarding buses to take them back to kunduz in the north.

this man was injured there in a gunfight there. translation: yes, - i want to go back home. we don't even have food here, and i haven't been able to geti treatment for my arm. a nation wounded by war, a people pushed from their homes. afghanistan's long conflict turns another corner. no—one's sure yet where it will lead. lyse doucet, bbc news, kabul. well for more on the evacuations from afghanistan i asked the bbc�*s nomia iqbal in washington if it seems president biden is determined to stick to the 31st august deadline. that is right. he is staying firm on it but i have to be honest with you, it is not a surprise that he did not extend the deadline because the cold truth of the matter is that it is notjust the us calling the shots, nor is it the other 66 nations of the eu of the un or nato who were all in the meeting with president biden. the truth is that the people in

control right now are the taliban and the taliban have issued this threat. they have repeated it again that if american troops stay beyond august 31 then there will be consequences so why on earth with president biden or indeed any leader of any country want to jeopardise security of their troops by keeping them there? and i thinkjo biden is very mindful of that and has been defied throughout this whole process and i don't think anyone expected him to change his mind. what he came across as during that press conference or someone very confident that this evacuation mission will go to plan and he points out that since august 12 more than 70,000 people have been flown out of kabul and he says that they believe that they have enough time, they have enough resources to get everybody out there that wants to get out. other not a few politicians that they too are saying it is bad enough to be heading out of afghanistan with our tail between our legs but to be pushed around taliban that a

moment of crisis like that is unforgivable? it is quite staggering, isn't it? because of course this was the group that 20 years ago america went into get rid of them and now they're calling the shots and i tell you, you can imagine, the republicans here in the us are massively using it againstjo biden. they're probably conveniently forgetting that it was actually donald trump, mr biden�*s predecessor, who made that agreement with the taliban but this is the difficult position that the us administration finds itself in. and i think that they are hoping, overthe and i think that they are hoping, over the next week, a leap of faith, that the taliban were complying. there is no reason to suggest they won't and i think after august that he fed us when everything becomes a little bit more difficult and more unclear but it is important to remember that i think it is probably on the telephone's interest for everything to go smoothly. this is a big moment for them. they want to assert authority, they want to assert authority, they want legitimacy and i think

that they will, you know, look at all the press, said that they are doing for example so i think that is at strange relationship. i think both sides are hoping it will go to plan. i think calling this next week the most crucial moment of jo biden�*s presidency is probably an understatement. jo biden�*s presidency is probably an understatement. the united nations says it has credible reports of human rights abuses by the taliban in afghanistan — including summary executions, the recruitment of child soldiers and restrictions on women and girls. the un human rights high commissioner michelle bachelet says women's rights are a "fundamental red line". one women's rights activist — afghan singer aryana sayeed — says she feared for her life and had to flee. courtney bembridge reports. iama i am a singer and a women's rights activist from afghanistan. it is for these reasons that she has fled her home country. two days after the taliban ended kabul she made it onto a us plane with herfiance. he made it onto a us plane with her fiance-— made it onto a us plane with her fiance. . , . ., her fiance. he was lucky enough that one of _

have to be part of future 6overnment structures and processes that is why un women are staying and delivering along with several other members of un family in cobble. we think it is really important to ensure there is participation of women in whatever form of government emerges. but also, that there is a tension paid for it now to the fate of what is happening to women, women's human rights defenders. we need to ensure that they can move around freely. that there is access, humanitarian assistance made available to women and that they have access to life—saving services and that they are freedom of movement and that girls can go to school so we have to continue to engage and to push and advocate for this. you say courageously you will stay on the ground to do that and i appreciate it is not for you to explain the stance of the human rights council, for example. that involves the politics of a good number of

member states but there is that big question. is the un, our international community organisations, doing enough? are they prepared to do enough? well, i mean, look. sending the signalthat well, i mean, look. sending the signal that we are not leaving and that we are there to work for the people of afghanistan is a really important message. and i think that is, that actions speak louder than words. and we are there and we will continue to provide humanitarian assistance. we haveissued humanitarian assistance. we have issued a plea for more humanitarian assistance because food is running out, life—saving medical supplies are running out on the situation of women's human rights defenders continue to get worse and worse every day. presumably you can only do that as long as the taliban will allow you to. when we hear word from taliban leader saying that on a temporary measure only women are actually being encouraged to stay out of the

picture for a moment. don't go to work and stay at home. how temporary, honestly, do you think that is? we temporary, honestly, do you think that is?— temporary, honestly, do you think that is? we don't know. we did honestly _ think that is? we don't know. we did honestly don't - think that is? we don't know. we did honestly don't know. l think that is? we don't know. i we did honestly don't know. the situation is very fluid and it continues to evolve by the moment. we hope that the taliban are going to keep their word when they say that women will be allowed to go to work and they said that women have been asked, everybody has been asked to come back to work including women but what we're saying is that there are actually real restrictions on women's freedom of movement and that the walking is not yet matching the talking. how to mana . e matching the talking. how to manage a — matching the talking. how to manage a relationship - matching the talking. how to manage a relationship with l matching the talking. how to l manage a relationship with the taliban going forward? i5 manage a relationship with the taliban going forward? is at the un level. _ taliban going forward? is at the un level. a _ taliban going forward? is at the un level. a un - taliban going forward? is at the un level. a un country| taliban going forward? is at the un level. a un country team are, the secretary generals special web centred above the un country team... light becomes a return trapped on that but ijust think even been called un women is probably even a challenge too far for the taliban. that might be but

we are still there. that might be but we are still there. and for more on the situation in afg hanista just go to our website — where there is a live page updated with all the latest developments on those evacuations — as well as a breakdown on how many afghans are leaving — and where they will go. stay with us on bbc news — still to come.we look at the potential economic and environmental benefits of using hydrogen as a fuel for the future — in our series climate critical he's the first african—american to win the presidential nomination of a major party, and he accepts exactly 45 years ago to the day that martin luther king declared, "i have a dream." as darkness falls tonight,

withdrawal deadline — he tells g7 leaders any delay increases the threat of violent attacks. in kabul — desperate scenes at the airport as the taliban say no more afghans will be allowed there. every week at this time we're taking a look climate change , bringing you a different topic or story. today we're going to be looking at hydrogen. billed by some as the ultimate fuel for the future — hydrogen has huge economic and environmental potential. it's an abundant resource and can be used to power vehicles, heat homes and in a wide variety of industrial settings. no carbon emissions at all only water. dinner to be used to produce it comes from solar. fossil fuels can be cheaper. it is called

blue hydrogen if the co2 emissions are captured and stored. black and brown hydrogen, well, that comes from different types of coal but the c02 different types of coal but the co2 emissions come with that. well — here in the uk, government plans to promote blue hydrogen alongside its clean, green alternative have been widely criticised. renewable energy firms and environmental groups say the long—awaited uk hydrogen strategy lacks ambition as it still relies on fossilfuels. let's speak now to one man on a mission to show that the future of hydrogen really is green. andrew clennett is co—founder and ceo of green hydrogen company hiringa energy. he's in taranaki, new zealand. thank you forjoining us. look, goodness, you are in a country which is rife with renewable energy in any case, i think, really. you actually need hydrogen? i really. you actually need hydrogen?— really. you actually need hydrogen? really. you actually need h droaen? ., ., , hydrogen? i think the key thing that hydrogen _ hydrogen? i think the key thing that hydrogen that _ hydrogen? i think the key thing that hydrogen that you - hydrogen? i think the key thing that hydrogen that you do - hydrogen? i think the key thing that hydrogen that you do is . that hydrogen that you do is connect that wonderful renewable energy to the parts of the economy and parts of our energy use that readers can't

simply get with electricity alone so it is what we call a vector that gets you into those hard to decarbonise parts. what hard to decarbonise parts. what would you _ hard to decarbonise parts. what would you say — hard to decarbonise parts. what would you say are _ hard to decarbonise parts. what would you say are the _ hard to decarbonise parts. what would you say are the most - would you say are the most valuable uses of hydrogen, then? ., , valuable uses of hydrogen, then? . , ., then? really it can hit a number _ then? really it can hit a number of _ then? really it can hit a number of areas. - then? really it can hit a number of areas. a - then? really it can hit a i number of areas. a classic then? really it can hit a - number of areas. a classic area you might have had about as transport. and transporting particularly heavy transport with a lightness of hydrogen, the ability to get energy into a vehicle quickly and keep that on the road, earning the money, and also to manage the payload. heavy transport is really exciting so from trucks, from buses, trains, planes, ferries, all the sorts of things, that is a really good one. heavy transport. the other one is industrial processes where we use hydrogen already but queen hydrogen so hydrogen which is produced from renewable energy rather than fossil fuels so there is feeding queen hydrogen into those industrial processes

so we can still make the molecules that we need, for example, but we can make them in a much more renewable way without the emissions associated. i5 without the emissions associated.— without the emissions associated. , ., ., associated. is the no value in no carbon — associated. is the no value in no carbon hydrogen? - associated. is the no value in no carbon hydrogen? that i associated. is the no value in no carbon hydrogen? that is| no carbon hydrogen? that is what the uk strategy is built abound. blue carbon. they capture the carbon. that is a positive thing, isn't it? absolutely. don't let perfect to get on the way of better. but that comes down to, you know, you've got the situation in the uk where that is the resources you have. here in new zealand, as mentioned, we have a plethora of options for renewable energy and so it is incumbent on us to apply those renewables to help solve the problems. queen hydrogen needs scale and how can we create that scale?— scale and how can we create that scale? that is really good oint to that scale? that is really good point to make _ that scale? that is really good point to make because - that scale? that is really good point to make because we i that scale? that is really good | point to make because we look at electric vehicles, for example. the scale is there another example of a use to them and get the idea, have you sort of been trumped by the ability to produce you know,

well one country struggling to cope with the impact of climate change is brazil. the country's supreme court is due to make a ruling which might have a profound effect on the country's indigenous people — as well as the future of the amazon rain forest. the decision could restore territory that was lost decades ago. it might also become an obstacle to further deforestation. the bbc�*s tim allman reports. for generations the clan have lived among these hills, fished in these waters. a proud people, they maintain their rituals of dance and pear. they used to own so much more of this land but then the settlers moved in. translation: before they killed us slowly one by one now they can as with the stroke of a pen, slowly. they have been reduced to the small corner of their ancestral lands that have an area prone to landslides, too steep for agriculture. translation: cowie to grow plants? we live in this hole, there is no way we can move and that's why we are fighting. as

they don't do what we want we will fight. and hundreds have taken that fight to the capital brasilia. their case hinges on an interpretation of the country's constitution adopted in 1988 which tribes were officially recognised at that time of what land where they are entitled to. the consequences could be huge. thousands of hectares sold by the state to private companies including tobacco companies in the 1950s will be returned to their original owners. translation: it is very sad. brazilian society needs to understand that we don't want anything that belongs to someone else. we only want what is documented, which are the traditional lands of our people. the government insists that too few indigenous people living on too much land and blocking economic expansion. they disagree and if they lose

they say they will resist until they say they will resist until the end. the drummer for the rolling stones — charlie watts, has died at the age of 80. his spokesman said, he passed away peacefully in a london hospital — surrounded by his family — and described him as one of the greatest drummers of his generation. david sillito looks back at his life. ijust play the drums for keith and mick. i don't play them for me. charlie watts — cool, calm and distinctly dapper, the steady back beat of the rolling stones. i can't play the drums at home, so i walk around and to play the drums i have to go on the road. i get a terribly vicious circle. it's always been my life. a graphic designer by trade, he was not expecting his evening sideline with a little blues band called the rolling stones to make him famous.

i'm @ bbcdavideades. hello there. western scotland was the warmest part of the country on tuesday and it will be again on wednesday. we had cooler, cloudier conditions in some parts of the country, mind you, particularly here in the midlands, and that cloud is still around in the same place at the moment. high pressure still in charge, keeping it dry, but we've got more cloud coming down across the north sea that'll push further inland during the day. but we start with some mist and fog patches in scotland and northern ireland, then the sunshine comes out in many areas. there's the cloud coming in off the north sea, into eastern england, through the midlands and towards parts of wales. and we'll have more cloud again

across the northern isles of scotland, but also, cloudier skies in the northeast of mainland scotland, perhaps even into the borders as well. elsewhere in scotland, the sun will be out and it's going to be warm — 26 degrees again around 6lasgow. and in the sunshine in northern ireland, 2a celsius. could make 2a in cumbria as well. cloudier, cooler weather, though, for northeast england through lincolnshire, the midlands, into east wales, but also for east anglia. sunshine more likely across southern counties of england, though in the southeast, it's still quite a chilly wind blowing, and we've got all this cloud coming further inland during the evening. so, a lot of cloud, i think, at headingley for the first day of the test match. it's going to be dry. it'll be dry for day two on thursday, but it will feel quite a bit cooler. now, we saw all the cloud in the north sea. it's actually on that weather front there, very weak. it's pushing inland during wednesday night. a little light rain or drizzle here and there, and by the time we get to thursday morning, it's cloudy and damp across wales and the southwest. but the cloud should thin and break. sunshine comes out across many western parts of the uk, but there'll be more cloud blown in by a strong wind off the north sea into eastern scotland for a while, but more especially across eastern parts of england.

and here, temperatures may be no better than 16 or 17 degrees. further west in the sunshine, it will be warmer, although not quite as warm as wednesday. with that weather front out of the way by the end of the week, we still have high pressure in charge. still a cool breeze coming in around some of those north sea coasts, and we'll see some cloud developing, particularly inland across england and wales on friday. more in the way of sunshine for scotland and northern ireland, and the weather should brighten up a bit more across east anglia and the southeast. but temperatures are going to be near 18—20 celsius at the end of the week.

this is bbc news — the headlines... president biden has said he believes the mission to evacuate people from afghanistan can be finished within the next week. but he warned this depended on continued cooperation with the taliban. earlier — mr biden said he was worried kabul airport might see attacks from islamic state—affiliated militants. the taliban have said afghan nationals may no longer travel to kabul airport — citing the chaotic situation there. in a direct appeal to the americans, the taliban spokesman urged them not to entice afghan nationals to emigrate saying their professional expertise would be sorely needed. stars of the music world

have been paying tribute to the talents of charlie watts — the drummer with the rolling stones for almost 60 years who's died in london aged 80. fellow drummers praised him as the beating heart of the stones — and a unique talent. now on bbc news, time for panorama. after nearly 20 years of war and over 100,000 dead, afghanistan is once more in the grip of the taliban. just weeks before the fall of kabul, i was there to see a country bracing itself for the withdrawal of us forces. every morning that i wake up i worry that we might lose another colleague. i met taliban leaders who claim they've changed... there was, in the past, some mistakes that we have learnt from. ..but with the future

of millions of afghans at stake, and concerns about global security,
