a spectacular but destructive display, and the only option is to get out of its way. and — the british ministry of defence launches an urgent investigation — after a serious data breach compromises the safety of afghan interpreters. it's seven in the morning in singapore, and it's 7 in the evening in washington dc — where the us government has announced plans to relax restrictions on air travel for fully vaccinated nationals in early november. travellers from brazil, china, india, and many european nations, including britain, will be able to board flights. covid testing and contact tracing will be needed, but not quarantining. near blanket restrictions were imposed 18 months ago at the start of the pandemic here's white house press secretaryjen psaki. we'll be putting a place strict protocols to prevent the spread from passengers flying internationally. we require adults travelling to the united states be fully vaccinated. obviously, this is the conclusion of a policy process on that particular issue. let's take a look at some of the detail of that easing of the us travel ban. from november, people who can prove they have had a full course of vaccinations will be able to fly to the us. they will, however, still have to take a test, before flying, to prove they are not infected with covid. and they will have to confirm where they are staying in the us, so contact—tracing can take place. our north america correspondent david willis has more. that is yet to be fully ironed out. there is this requirement that people be fully vaccinated before they come here, but what does that mean? does the russian vaccine count, does the astrazeneca vaccine count? then there's the question of producing evidence of a covid test. undertaken within three days of travel. the full pcf or the lateral flow test, which of those counts? a lot of ambiguity here and, as well, regarding children under the age of 15 who have not been fully vaccinated. what does it mean for them. vaccinated. what does it mean forthem. detail vaccinated. what does it mean for them. detail in the words of the white house but the sort of the white house but the sort of detail which particularly potentially affects millions of people. potentially affects millions of --eole. ., , ., potentially affects millions of --eole. ., ., ., people. people who have not seen their— people. people who have not seen their loved _ people. people who have not seen their loved ones, - people. people who have not| seen their loved ones, friends and family for 18 months or so. ijust want to and family for 18 months or so. i just want to ask you about something else. this is coming, the timing of this is very interesting, with the deal that we have talked about with you. partners like the french being very upset about being left out of that security pact. do you think that this is a way to sort of apply some balm to that wound, perhaps? the sort of apply some balm to that wound, perhaps?— wound, perhaps? the timing of the announcement _ wound, perhaps? the timing of the announcement are - wound, perhaps? the timing ofi the announcement are certainly very interesting and quite crucial in some ways perhaps because not only, as far as the french are concerned we have the british prime minister borisjohnson in washington at the moment. he is due to meet with president biden at the white house tomorrow and he was due to press my report suggested, for a lifting of these restrictions. now he has got something to cheer, he might have to get to that president biden but earlier in the day today it emerged joe biden are seeking a call with his french counterpart against the background of very tense relations following this deal between the united states, australia and the uk. this defence and security arrangement which is basically carved the french out of the arrangement. if there is that sort of conversation and the french have yet to confirm that there will be. this is at least something that president biden can use to perhaps attempt to assuage the rather frayed nerves of his french counterpart. and there's much more on the easing of the us travel restrictions on our website — including a look at how the new rules will be enforced. just log on to bbc.com/news well, as we've been reporting, as that announcement was being made, the british prime minister borisjohnson was in new york, to attend a meeting of the united nations. he's urging fellow leaders to sign up to financial and environmental targets, ahead of november's climate change conference, called cop26, in glasgow. our political editor laura kuenssberg reports from new york. an emergency unfolding. the point the prime minister travelled to new york to make. the united nations, meeting here, is not united in how to slow down changes to the climate, how much to spend, how much carbon to save. we are close to the moment to start. borisjohnson�*s mission, to try to push other countries into line. everybody always agrees that something must be done. saying something isn't enough for him. it's only chance that has put the uk in charge of trying to get global agreement this autumn, so success or failure is about political ambition as well as the planet. saying something isn't enough for him. it's only chance that has put the uk in charge of trying to get global agreement this autumn, so success or failure is about political ambition as well as the planet. we have to grow up and take our responsibilities. i think we go through a period of, you know, glorious indifference about the world. we've been through that. we've been through our childhood, if you like. we've now got to realise that this is a problem that requires grip. the official international machine urges progress. our world is challenged like never before. from climate change to conflicts, to covid—19. it would be easy to lose hope. but we are not hopeless. yet, what hope is there, really, when vast countries like china, india — huge emitters of carbon — aren't quite so keen? strangely, this meeting really matters to downing street because of the next big international shindig at home — the climate conference in glasgow at the beginningof november. the prime minister wants all countries, big and small, wealthy and less so, to make more dramatic promises to cut their carbon, and for the richer ones to put their hands in their pockets to help the others go green. right now, he only puts the chances of that happening in time at six out of ten, so there is a real demand for borisjohnson to create momentum here in manhattan. but whose mind can he change? the outspoken brazilian leader, who's let the amazon forest burn. borisjohnson had vowed to telljair bolsonaro to stop what's going on. but when they actually met, it looked rather friendlier than that. the prime minister urging the brazilian to get the astrazeneca vaccine. get the astrazeneca vaccine. that appeared to have fallen on deaf ears. but every country here this week has its own political climate. every country, its own interests, too. the american president, on his way to new york tonight, will tomorrow reveal more of his own. laura kuenssberg, bbc news, new york. let's take a look at some other stories in the headlines. the pharmaceutical giant pfizer says it will seek authorisation to use its covid vaccine on children as young as five years old. the company says it carried out a trial after the number of pediatric coronavirus cases more than tripled across since the us sincejuly. the vaccine is already cleared for use for children aged 12 and up in several countries. migrants have continued to cross the border from mexico into the us, despite america flying several planeloads of people back to haiti. these pictures show people going back and forth across the rio grande between acuna in mexico and del rio in texas. reporters say many are joining the camp underneath a road bridge where other migrants have gathered. england have cancelled the upcoming men's and women's cricket tours of pakistan days after new zealand abandoned their series over security concerns. both teams were due to play pakistan in two twenty20 internationals next month with the women additionally playing three one—day internationals — all in rawalpindi. still to come a bit later in the programme: we'll have the latest from canada as they head to the polls for the second time in as many years. but first. on the spanish island of la palma, part of the canary islands, thousands of people have been moved from their homes, a hundred homes have been destroyed, and flights have been cancelled, after a volcano erupted yesterday. the flow of lava, 15 metres high in places, destroyed everything in its path. it's the first time in a half—century that the cumbre vieja volcano last erupted. our correspondent danjohnson is on la palma with the latest. homes that once enjoyed views of this island's impressive volcanic landscape are now being smothered under it. the relentless downhill creep of molten lava burns its way through anything it touches. the eruption follows a week of tremors, but nobody has seen anything like this on la palma for half a century. "look, look, it's falling", the man says. another house destroyed. that's more than 100 now, either burned or buried. "eight metres of lava", he says. these are the strongest forces of nature at work in a spectacular but destructive display, and the only option is to get out of its way. translation: right now, the most important thing l is to guarantee security. we are still in the eruption phase. please, let's be extremely careful. so, residents of four villages have been ordered to safety and some tourists have decided to go home. i am worried, i am sorry for all the people who are losing or have already lost their houses. there is no good feeling now on this island and therefore. we want to leave as fast as possible. _ this is a disaster movie in slow motion. the lava keeps crawling towards the sea. spain's tourism minister sees an opportunity, a chance to entice tourists back to view the eruption from a safe distance because nobody knows how longthis will last. danjohnson, bbc news, la palma. just a few hours to go in voting in canada's general election — the second in just two years. it was called by this man — prime ministerjustin trudeau — who says he wants his liberal party to be able to govern without a coalition. but — he's facing a close fight with erin o'toole — head of the centre right conservatives. it's his first campaign as a party leader — and he has criticised the way mr trudeau handled the pandemic. our correspondent samira hussain is following developments from montreal. canada's prime minister said he called this election because the pandemic change to the country and canadians should have a say in what happens to canada going forward. the opposition says that this is actually nothing more than an expensive political ploy by mr trudeau to try and get a firmer hold on power and gain a majority in parliament. and the voting public? well, they are just suffering from election fatigue. this is the second time canadians are going to the polls in less than two years. the first was mandated by law, but this election is really aboutjustin trudeau trying to gain this majority. but if you look at the polling, he is now in a statistical tie with his main opposition rival, which means that this political gamble may actually backfire, and he could even lose his seat as prime minister. the voting across canada's time zones continues for a few hours yet — but samira will be up all night, with the results as they emerge — so do stay with bbc news for that. you're watching newsday on the bbc. still to come on the programme. from olympic gold medallist to environmental campaigner — australian swimmer — bronte campbell — tells us about the impact climate change is having on sport. benjohnson, the fastest man on earth, is flying home to canada in disgrace. all athletes should be clean going into the games. i'm just happy that justice was served. it is a simple fact that this morning, these people were in their homes. tonight, those homes have been burnt down by serbian soldiers and police. all the taliban positions alongj here have been strengthened, presumably in case i the americans invade. it's no use having a secret service which cannot preserve its own secrets against the world, and so the british government has no option but to continue this action, even after any adverse judgment in australia. concorde had crossed the atlantic faster than any plane ever before, breaking the record by six minutes. this is newsday on the bbc. our headlines: a sudden change of policy — as the united states says it'll lift the ban on international air travel for fully—vaccinated foreign nationals in november. uk prime minister — borisjohnson — says he's �*increasingly frustrated' the richest nations continue to deny funding to developing countries to help them adapt to the climate change crisis. a bbc investigation has found the uk's ministry of defence compromised the safety of afghan interpreters, because of a serious data breach following the withdawal of western forces from afghanistan. more than 250 people, who are seeking relocation to the uk, were mistakenly copied in to an email, asking for an update on their situation. the uk defence secretary will launch an urgent investigation into the bearch, describing it as "unacceptable . our special correspondent lucy manning has more. well, the defence secretary tonight has launched an urgent investigation into what he is calling this unacceptable breach. it comes after bbc news discover that the bbc misses containing names and photos of some of the interpreters and other workers who had worked for the british had been circulated wrongly in an e—mail and obviously there's concern is that that e—mail might get into the wrong what happened was the relocation team, based at the mod in london e—mailed those interpreters and workers who have not made it to the uk and either hiding in afghanistan or third countries, to get an update from them. one interpreter realised that there were 250 other e—mail addresses, names and photos on that e—mail. and one interpreter said this mistake could cause the lives of interpreters especially for those still in afghanistan. the mod tonight has apologised. it has launched an investigation but it is another misstep in this evacuation of interpreters from afghanistan. meanwhile in afghanistan itself, fears are growing of an overwhelming humanitarian crisis. the united nations say that after decades of war the people of the country �*face perhaps their most perilous moment�*. the un world food programme says only 7 percent of afghans have enough to eat. the bbc�*sjeremy bowen in is kabul, and he sent this report on conditions there. the struggle to live, to eat, to survive did not end when the shooting stopped. at first light, hundreds of building workers looking for a day�*s employment gather at a market place in the centre of kabul. with their tools and without much hope. afghanistan�*s economy is closing down. millions live in poverty in a country that has received huge sums in foreign aid. these men rage about the fortunes stolen by a corrupt elite in the last 20 years. food prices are rocketing. millions barely feed theirfamilies. hunger could become the worst of afghanistan�*s many crises. $9 billion that might help them was frozen by the americans to keep it away from the taliban. in the name of allah, we call on america that they must give the money in the budget that they have directed from afghanistan, they must recognise our new government... ..afghanistan. malnutrition is a chronic problem in afghanistan. only patients with other severe complications, like three—year—old mohammed, have a chance of a bed at kabul children�*s hospital. but more patients are arriving. the doctors said that was because the world bank stopped funding village clinics after the taliban victory. life was never easy in afghanistan. seven—month—old mohammed is his mother�*s fourth living child. six others died at birth. like all the other women in the corridor, she wanted to hide her identity. not a new thing in afghanistan, but under the taliban everyone is more cautious. taliban fighters are highly visible in kabul. some here say security is much better now the fighting is over. for many, it is quiet built on fear. countries that want to help afghans but detest the taliban and all that they stand for are in a bind. for people to earn money, to buy food, to look after theirfamilies, the taliban needs to preside over a viable state. now, for the americans, the british, nor the other countries that fought the taliban for so many years, that might be just too much, especially if the taliban can then claim another victory. a community high above the city carries the scars of a0 years of war. so do the families who live here. this family is leaving for pakistan. the mother, the only breadwinner, taught male students. the taliban stopped her job and her younger daughter�*s education. their dreams were always fragile in a state riddled with corruption, which couldn�*t survive the departure of its foreign backers. afghanistan�*s newest crisis is about fundamentals of life — food, security and hope — and the despair and anger when they have gone. jeremy bowen, bbc news, kabul. athletes in australia are raising the issue of how climate change is adversely affecting sport. the athletes highlight how the increase in extreme weather events and more intense heat has forced early retirements at the australian open tennis tournament and bushfire smoke has caused the cancellation of training and matches. more than a50 athletes have joined a campaign called the cool down and they�*re calling for the authorities to do more to tackle climate change. climate action campaigner — australian swimmer and olympic gold medallist — bronte campbell — explained the thinking behind this. it is an exciting initiative not set up by me. david started approaching athletes in st madge want to do something on climate change. and all athletes just wanted to get behind that not only focus on the environmental impacts which are obviously huge butjust highlighting it is notjust the environment. it is livelihoods and how we live our lives and most people in australia care a lot about sport and highlighting the fact that sport is not going to look the same. we�*ve had the hottest decade on record but could be the coolest of the ones going forward. so we�*re really looking to save the environment but also look at the broader of what climate change means for us as a country.— us as a country. what are you callin: us as a country. what are you calling on — us as a country. what are you calling on people _ us as a country. what are you calling on people to _ us as a country. what are you calling on people to do? - us as a country. what are you calling on people to do? how| calling on people to do? how will this initiative change or help the way people behave and so many others have failed? there is a lot of talk about it and that is why we are going to want to talk about and raise awareness and say, join the movement. that is a very powerful thing on an individual level but we are talking about policy change in the government level. going to zero emissions. calling on the government to set those ambitious goals and then figure out a road map together. to then figure out a road map together-— together. to think that the government _ together. to think that the government is _ together. to think that the government is doing - together. to think that the l government is doing enough together. to think that the - government is doing enough on the climate change fund to tackle the serious problem for you and australia?— tackle the serious problem for you and australia? look, there is alwa s you and australia? look, there is always more _ you and australia? look, there is always more the _ you and australia? look, there| is always more the government can do and setting those goals, we don�*t really know how we get to those goals were not going to those goals were not going to set about making a commitment like athletes do in sport by setting an ambitious goal and then going for it because it is sort of a political football that gets kicked around and we just want to focus on getting the right things done so listen to the climate experts and make some commitments is what we are asking for. you have been watching newsday. that�*s all for now — stay with bbc world news. hello there. for central and southern parts of the uk this week, it�*s not going to be looking that bad at all. with high pressure always nearby, it�*ll be dry, quite warm with plenty of sunshine. but we�*ll start to see some changes from wednesday onwards across the north of the uk, more especially for scotland, where it will turn windier with some rain at times and it will feel cooler. so, a bit more of an autumnal feel there. high pressure, though, dominates the scene into tuesday, many places starting dry. there will be some mist and fog around, some dense patches across east anglia and the southeast which will tend to dissipate through the day. bit of mist and fog to start the day for scotland and northern ireland, and then it�*ll turn cloudier and windier for western scotland, perhaps western northern ireland, with some light and patchy rain here. but eastern scotland, eastern northern ireland, most of england and wales, fine and dry with some sunshine. and again, feeling quite warm, temperatures into the low 20s celsius. into tuesday night, it starts to turn cloudier, windier and wetter across the northwest of the uk. further south, closer to high pressure, winds will be lighter, there will be some clear spells again, one or two chilly spots, but a bit milder further north and west. this is where we start to see the changes, then, around the middle part of the week. indeed, it�*s on cue during the autumn equinox, with some rain and strong winds pushing in to scotland, northern and western areas, and then this band of rain will move southwards into northern ireland, southern scotland later in the day. behind it, sunshine, blustery showers, gales here. to the south of this rain band, though, for the majority of england and wales, another fine day to come. and quite warm, top temperatures of 22 or 23 degrees. as we move into thursday, another area of low pressure skirts the north of the uk. that�*ll bring another swathe of wet and windy weather across scotland, maybe some gales later in the day. a bit more cloud further south, but again, for much of england and wales, the midlands southwards, it�*ll be dry with some lengthy spells of sunshine, top temperatures 20 or 21 degrees. but cooler in the north, ten to 16 degrees here — particularly chilly when you factor in the wind. through friday and then into the weekend, we start to see the winds change direction. low pressure develops to the west of the uk. that draws up some mild south—westerly winds across the uk, but we�*ll start to see some wet weather pushing into western areas as we reach part two of the weekend. but again, across the south, it could stay dry with plenty of sunshine. the headlines will follow after this programme. hello, welcome to the media show. now, this week, we�*ve become aware of power battles within the taliban as we watch keenly to see what kind of government it wants to create. also this week, we�*re seeing increasing evidence the world�*s media is tuning out of afghanistan. well, we�*re not doing that on the media show — we�*re going to tune in to how western media and afghan media have covered this story. i want to understand the relationship between the taliban and journalists.
