rescue workers in lebanon are searching for a possible survivor from the port blast in beirut, that devastated the city a month ago. a sniffer dog alerted rescuers in the rubble of a collapsed building and the team then said their scanners had detected a pulse. they've been digging ever since and they say they'll keep going even if there's only a one percent chance of finding someone. our international correspondent orla guerin has been watching them work all day. hands up for silence. rescue workers and many in this battered city wait for a sign, daring to hope. and then, beeping that confirms breathing has been detected beneath the rubble. could there really be a survivor 30 days on? rescuers from chile have been

carrying out painstaking work. their key team member, a border collie called flash, who was the first to raise the alert when he detected a body at this location. night falls and floodlights are brought in, s the search continues, hour by hour. some rescue workers go back in. nearby, others regroup. the rubble is being removed here piece by piece, by hand. well, they're getting set up here now to work through the night. they're setting up a tent as an operations room. and the rescue team has been telling us that they're going to be divided into groups of seven — only seven will be allowed up on the rubble at any one time because they're so afraid of dislodging any of the wreckage. they have to proceed

slowly and painstakingly. translation: the dog detected something, and the technology also detected a place in the building — the same point of interest as for the dog. it's four metres deep. it doesn't mean someone is alive or dead in the building. we have to get to that point and confirm. later on during the evening, the search teams, the chilean experts, said they had to stop because they were worried one of the walls was going to completely collapse. they've pulled out their teams, they said they would now need to secure the site, secure that wall before they could continue, and they left for the night. orla guerin, bbc news, beirut. the us presidential candidatejoe biden has been visiting kenosha, winsconsin, the city that was rocked by violent unrest last month after police shot an unarmed black man, jacob blake, in the back. mr biden called mr blake in hospital, and had a private meeting with his family. they had refused to meet president donald trump

when he visited the city on tuesday. this report from our north america correspondent, aleem maqbool, contains footage that some viewers may find distressing. a rare trip in this pandemic forjoe biden. an indication ofjust how important events here have become in this election campaign. donald trump knows it, he's already been to kenosha, where he focused on condemning rioting and lawlessness. joe biden, though, talked of racial injustice, and criticised the president for stoking troubles. i've got to defeat hate. it only hides, it only hides, and when someone in authority breathes oxygen on to that rock, it legitimises those folks to come on out. unlike donald trump, joe biden met the family ofjacob blake — he himselfjoined by phone from hospital. it was his shooting by a police officer that started all of this.

but this spot had other visitors from out—of—town — nephews of george floyd. we're out here in kenosha, showing our love and our prayers for kenosha, man. that's it. neighbours came out to meet them, and thanked them for their family's work since their uncle was killed by a police officer, who knelt on his neck. a loss that is still clearly very raw. thank you for taking yourself out of your comfort zone so we can have a voice with action. exactly. and what is that action? george floyd's family told me the most important thing now is to vote against donald trump. we demand change. so this is what's going to happen, we need to get out there and vote, vote him out. from our city officials, locals, our police officers, everybody, you're not with this movement — you need to go. hey, get on the ground. get on the ground. all this comes as newly—released police video shows yet another disturbing case. daniel prude was having

a mental health episode when officers handcuffed him and knelt on him. he stopped breathing, and died several days later. the medical examiner ruled it as homicide. i placed a phone call for my brother to get help, not for my brother to get lynched. donald trump and joe biden have now laid out their very different stances on race and policing. which appeals the most depends on which side of this deeply divided country a voter finds themselves. aleem maqbool, bbc news, in kenosha, wisconsin. geoffrey kabaservice is the director of political studies at the niskanen center in washington. thank you forjoining us. how big a part will more and order play in the elections looming ever closer? it is not clear but it is clear that donald

trump really has no other cards to play except to hope that by calling joe biden weak on crime and looting, he could alarm a sufficient number of swing voters, particularly in suburban middle—class districts to win the electoral college. joe biden has opposed the funding the police and has a track record of being tough on crime. is he getting it right. —— defunding. crime. is he getting it right. -- defunding. it is nuanced. joe biden is on one hand saying that writing is wrong but on the other hand saying police misconduct is a terrible thing and siding with the black lives matter protests. donald trump is simply saying, support the police and writers are bad and he's not even distinguishing between nonviolent protesters and violent rioters. joe biden

in the past has called these protests in the past and rights, as domestic terrorist. that has gone down fine with this important base but that is not whoever is trying to motivate. ——he is. far more people are still more likely to say that donald trump is the one bringing chaos to the country and he would, in his second term, bringing the chaos level down. do you think the law and order vote is enough to secure a victory for donald trump? we are coming to three decades of declining crime. there is no doubt that the record of crime, it costs democrats dearly but i do not think that anyone is yet saying that what we have seen in terms ofan uptake that what we have seen in terms of an uptake of violence in

select cities and the rioting which overlap with the racial protests is going to cost the democrats yet. there is no evidence it is moving the dial yet. thank you very much for joining us. police in germany are waiting to question the mother of five children who were found dead in an apartment in the western city of solingen. the children were aged between one and eight. the woman is in hospital after being badly injured when she jumped in front of a train the afghan government and the taliban say they've completed a controversial exchange of prisoners, paving the way for peace talks to start. the process had stalled for weeks because some of the detainees demanded by the taliban were described as serious criminals by the afghan government. the taliban is also thought to have freed afghan government captives, including commandos. more than 300 people have been arrested during a third day of climate change protests in central london. the metropolitan police said more than 200 arrests

were linked to a demonstration on lambeth bridge. some extinction rebellion supporters glued themselves to the ground around parliament. south korea has been praised for its efforts to contain the coronavirus, but has now imposed a near—lockdown in the capital city, seoul, after a surge in cases. experts say the situation has been made worse by extreme evangelical churches, who've convinced many followers that the pandemic is part of a government conspiracy. from seoul laura bicker reports. to his followers, he's an alt—right rock star. to others, this pastor and his church pose the biggest coronavirus threat this country has faced. thousands of new cases have now been confirmed, many of them from ultra—conservative churches. some worshippers,

many of them elderly, are refusing to be tested. they believe the virus was planted in the church by a government determined to silence them. i put it to this young follower that he is risking lives by failing to get a test. why are you not being tested for covid—i9 after being at the rally? it's proving a huge challenge for this country's virus hunters. usually, they can trace over 1,000 people an hour using mobile technology. but hundreds are refusing to go into quarantine. as cases increase, seoul's usually neon—lit social life has been forced to fall silent.

this is as close to a lockdown as the capital city seoul has had since this pandemic began. it almost feels like a curfew, because within the space ofjust a few minutes, these normally busy, vibrant, sometimes boisterous streets have come to a stand—still. translation: business is down by 90%. it feel like the whole world is falling apart. these church members once faced the wrath of the south korean people. they belong to the shincheonji church of jesus, a sect blamed for the country's early virus outbreak in february. they're now donating their blood plasma for treatment and research. as one religious group seeks redemption, another remains defiant, threatening this country's well publicised success in fighting the pandemic. laura bicker, bbc news, seoul.

stay with us on bbc news, still to come: straight to streaming as disney's mulan isn't released in cinemas has the pandemic changed the way we'll watch films forever she received the nobel peace prize for her work with the poor and the dying in india's slums. the head of the catholic church said mother teresa was a wonderful example of how to help people in need. we have to identify the bodies, then arrange the coffins and take them back home. parents are waiting and wives are waiting. hostages appeared. some carried, some running, trying to escape the nightmare behind them.

britain lost a princess today, described by all to whom she reached out as irreplaceable. an early morning car crash in a paris underpass ended a life with more than its share of pain and courage, warmth and compassion. this is bbc news, the latest headlines: one month after the blast that claimed so many lives, rescuers in beirut think there may be somebody still alive under the rubble of this building. joe biden travels to kenosha to meet the family ofjacob blake, and spoke to mr blake on the phone. is facebook doing enough to fight misinformation when it comes to political ads in the run up to the us presidential election?

it's founder, mark zuckerberg, has announced that it won't take on any new political ads in the seven days before the vote on november 3rd. he's worried about divisions in the country potentially leading to civil unrest. i'm joined now from new york by professor sinan aral from the massachusetts institute of technology. he's director of the initiative on digital economy and author of ‘the hype machine' on how social media disrupts our elections, economy and health. thank you very much for being with us. what exactly has facebook said it to? says it is going to prevent, in the last week before the election, new political advertising. that it is going to remove posts that claim that you can get covid—i9 by going to a voting station, that it will attach warning labels to content that seeks to delegitimise the outcome of the election, and it will stop campaigns from declaring

victory early in the election results. how unusual is this for a social media company to ta ke for a social media company to take this step and our other platforms likely to follow suit? we live in unusualtimes. in the social media platforms around the world have met with tremendous criticism over the last 18—24 months. they are under significant pressure, given the state of the relationship between social media and democracy and particularly elections, as you know. there were questions about the role of facebook and other social media platforms like twitter in the brexit vote as well as the 2016 us presidential election, so i don't know if there is a usual for how social media platforms behave in this day and age. i do think that misinformation and foreign election interference are significant threats that need to be addressed. we do see a rise in disinformation on social media platforms but they also provide

an opportunity for people to call out that disinformation. is this going to make any difference? i think that transparent labelling of information is incredibly important. so, crowdsourcing labels of disinformation can help us understand the providence of information and therefore make better decisions about what to believe and what to share. i think that the platforms can do a lot more to use machine learning to identify misinformation as well. but we have to remember that labelling comes with some caveats. first, there is what is known as an implied truth effect, which is if you begin to label everything, uses begin to label everything, uses begin to think that things, if they aren't labelled they must be true, so if you can't get to everything, then this implied truth effect might imply truth about things that aren't labelled but that a false. and secondly, labelling of false news is known to reduce our confidence in the news in general, which can have

deleterious effects, so we have to tread carefully but there area to tread carefully but there are a lot of systematic things that going forward, the platforms need to do to protect democracy in elections. thank you forjoining us. people arriving in wales and scotland from portugal, must now self—isolate for 1h days, but the rules covering england and northern ireland have not changed. the rules for wales apply from 4 o'clock on friday morning, while in scotland they begin 2a hours later on saturday morning. cases of coronavirus in portugal have been rising in the past week. hundreds of african migrants die every year trying to make their way to europe, desperate to escape poverty and unemployment back home. the united nations says this summer has seen a "sharp reduction" in european countries' efforts to carry out search and rescue operations in the mediterranean, one of the main sea routes from north africa. it's making the crossing even harder, and many are getting stuck in libya and forced

to return home, as the bbc‘s lalla sy reports from dakar in senegal. the senegalese coast is a starting point for most migrants who aspire to reach europe for better living conditions. tidiane camara wanted to reach europe via libya. he left the casamance region, in southern senegal, and travelled to tunisa before entering libya. translation: one day, robbers came into the house at around 9pm. there were three of them and they started banging on the door. before i opened it, i asked if they were arabs or blacks. when they answered that they were arabs, i wanted to run away so they started shooting with guns and i was wounded in the leg. at first tidiane could not get medical treatment because he did not have a passport so his wound became infected and his leg had to be amputated.

after spending months in hospital, it was impossible for him to find work or to stay in libya so he asked to be repatriated. the senegalese who choose illegal immigration sometimes begin their dangerous journey from villages, such as this one, where we are, in the locality of malicounda, 80 kilometres from the senegalese capital, dakar, but many lose their lives along the way and, with more than 5000 deaths in 2017 in africa, migration is now one of the major causes of mortality, according to the international organization for migration. for those who return voluntary or forcibly, iom is working with the senegalese government to involve local authorities in the reintegration process. translation: not much has been donein translation: not much has been done in our country and we have a lot of progress to make. we

need more resources and operational programmes that will attract their interest and generate profit for them. among these initiatives is the community radio oxygen. it is based in pikine, the second—most populated city in senegal, where the poverty rate is close to 30%. the income per capita per day is less than $2. every wednesday, codou hosts a program that addresses communities on topics related to immigration. translation: we talk to these young men and women and to their parents, especially mothers, who can spend and borrow a lot of money or sell their assets for the departure of their sons so that they can provide for their needs and put them in better conditions. in malicounda, tidiane camara is managing the only food shop in his neighbourhood. in his quest for survival,

he might have lost a leg but has regained dignity. lalla sy, bbc news, dakar. russia's prime minister has been meeting the president of belarus, alexander lukashenko, in the capital minsk. he's the most senior russian official to visit since the disputed presidential election last month. moscow has issued strong support for mr lukashenko following weeks of mass protests over the poll, which the opposition say was rigged. production of the new batman film has been stopped after the film's star, robert pattinson tested positive for coronavirus. "the batman" charts the early days of the superhero as he tries to fight corruption in gotham city. almost six months after it was scheduled for its cinematic release, disney's live action remake of the film mulan is out on friday, but you won't find it in the cinemas. instead it's being released exclusively on disney plus, the company's own subscription streaming service. and with the film industry looking for ways to show

theirfilms in a post—covid world, could it be a viable way forward ? i spoke withjulia alexander, a reporterfor the verge, and asked her how things have changed due to coroanvirus. things are changing and the way that studios are now looking to innovate, so the big question with disney is can a $200 million blockbuster film like mulan perform as well on a strictly premium video on demand service as it would theatrically? that's the question people are posing but it is not necessarily the correct question. this is an experiment for disney ina number of different ways. but what the company is looking to do, really, is build the streaming service so what they are asking you to do is spend $30 in the united states, i believe it is a little bit cheaper in parts of europe, $30 to rent the movie. then, in order to keep that movie the next few months until it becomes free

to all disney plus subscribers, you have to pay $6.99 a month, so they asking you to not cancel your streaming service. can this help build disney plus, one of the company's key streaming initiatives, key services, one of its only profitable sectors right now, while also making money? and the other thing to mention that kind of get lost is, this is a disney plus exclusive in territories where disney plus exists, but this movie, mulan specifically, was always intended to play well in china where it will receive a full theatrical release and the chinese box office over the last few weeks has been pretty good in terms of what you are looking for when you want to release a movie like this. another big movie due

out this week is tenet, is that going to make the money it wants with the post—covid restrictions in place? it's not gonna make the kind of money that warner brothers was expecting in february that they were hoping it would make. is going to be profitable? i think so, and part of that is because it is going to get a big release overseas where people are going to theatres more often. when we look at the united states, it's going to go city by city, state by state, and they are looking at this as a long game. they are not looking at this as the traditional three—week main window where your movie is gonna make a lot of money at the box office. as more theatres open and more people want to get out, can tenet be the movie they want to go see? warner brothers is controlling more theatre spaces, they are the biggest presence so it could work out for them. but warner brothers and warner media are also looking at disney and mulan and how this plays out. could this be something they do with their next big film, wonder woman 1984? you can reach me on twitter,

i'm @richpreston. hello there. looks like we are all in for a dose of cooler, fresher weather over the coming few days. could be perfect weather for seeing some rainbows, just as we saw on thursday here by a weather watcher in scotland. further south, it's been milder and quite muggy for a while. temperatures ahead of the cloud and drizzle were as high as 23 celsius in the southeast of england. it's a cooler start to friday, temperatures in the clearer skies, typically 9—11 celsius. some more blustery showers in northern scotland, then towards the southwest, this cloud never really clears away. it comes back into the southwest of england and south wales — pushing eastwards towards the midlands and south east england. that will bring a bit of light rain and drizzle. further north, some brighter skies, some sunshine and some showers. those showers turning more widespread in scotland and northern ireland, pushing into the far north of england. disappointing temperatures, 17—18 celsius, fairly typically, could make 20 in the southeast ahead of any rain that arrives

during the evening. as we head into the weekend, high—pressure is close by, but it's towards the southwest of the uk. it leaves us with a run of northwesterly winds. that's going to drive in cooler air, and temperatures on saturday could be even lower during the day as well — it will be a chilly start to the day too. so, a cool weekend ahead. there will be this mixture of sunshine and showers continuing. as we look ahead to saturday, most of the showers will be in the north and west of the uk. quite a few showers, actually, across northern scotland, quite a few showers for northern ireland. those will stream over the irish sea into northwestern parts of england and wales. so, for the south and the east, it should be largely dry, some sunshine at times, those temperatures could be even lower, making 1a celsius at best through the central belt of scotland — 18 in the south of england. some more showers continuing overnight and into sunday.

should be a drier day though for northern ireland, a drier day for scotland. most of the showers across england and wales, some of those could be heavy as well. temperatures will be pegged back in those showers, but probably a degree or two higher than saturday across scotland and northern ireland, but still only making 16 celsius. those showers do move away during the evening as we head into the early part of next week. we've got lower pressure to the north of the uk, some weather fronts on the scene, higher pressure into more southern areas. so, that means for the first few days of next week, it's going to remain unsettled for northern areas. there will be some stronger winds, some rain from time to time. further south, it should be largely dry and warmer — temperatures into the mid—20s.

this is bbc news, the headlines: search teams in the lebanese capital, beirut, say they have found possible signs of life in a collapsed building — a month after the huge blast which destroyed parts of the city. rescuers said they'd detected a pulse 2 metres deep in the rubble in a residential area joe biden, has spoken by phone to jacob blake, the black man whose shooting by police in wisconsin sparked days of unrest. in a speech in the city of kenosha mr biden accused president trump of legitimising the dark side of human nature. south korea has now imposed a near—lockdown in the capital after a surge in cases. experts say the situation has been made worse by extreme evangelical churches — who've convinced many followers that the pandemic is part of a government conspiracy
