president biden's ambition for re—election marred by new claims he did not recognise a long—time friend and fellow democrat at a recent meeting. there have been sporadic clashes in the bangladeshi capital as the military enforces a national curfew to quell anti—government protests. and workers at disneyland claim they're not paid enough at the happiest place on earth, voting in favour of going on strike. hello, i'm tania beckett. the aviation industry says nearly 7,000 flights were cancelled on friday after a digital outage disrupted global computer systems. healthcare, banking and businesses

were affected worldwide. the crisis was caused by a faulty software update which affected microsoft windows systems. while many airline services are returning to normal, operators expect some delays and cancellations to persist throughout the weekend. and figures released by the airline data provider cirium say that, worldwide, more than 1,600 flights have been cancelled today. the global chaos has sparked concern over the vulnerability of the world's interconnected technologies, and the extent to which a single software glitch could have such widespread impact. and the uk's national cyber security centre is warning that scammers could attempt to take advantage of the widespread computer problems. vincent mcaviney has the latest. a day of worldwide it chaos, thanks to an update meant to protect systems but which instead paralysed them with this blue screen. train services and airports were badly affected

with thousands of flights grounded all over the globe, from the uk to asia and the us. this flight radar data shows us skies emptying out as the outage took hold. delays and cancellations are expected to persist for several days. here, medicine deliveries to pharmacies were disrupted and gps in england had problems accessing patient records. ambulance services across the country have reported a surge in demand as a result. if you have an urgent problem, you should contact your own gp surgery, either in person or by telephone. and if that's not possible and you're worried, then you are to go online and have a look at messaging from 111 or call 111. it even affected software used by broadcasters, knocking some tv channels off air. cafes, restaurants and shops were also left unable to process payments.

we had a lot of problems with the card machine. the cards are not going through. it'sjust there's no signal. at crowdstrike, we monitor trillions of cyber events... i the cause? a single update from this us antivirus company. you may not have heard of crowdstrike before but it has nearly 2a,000 business customers around the world, many of them huge organisations like airlines and banks. we stop a lot of bad things from happening. we're deeply sorry for the impact that we've to customers, to travellers, to anyone affected by this, including our company. so, we know what the issue is. we're resolving and have resolved the issue. now, it's recovering systems that are out there. to be clear, this wasn't a hack or cyberattack, so you don't need to change any passwords. it only affected machines running microsoft. but every single one will need a manual reboot in safe mode, which is not as simple as turning it off and on again. microsoft says some people have

to do this as many as 15 times. we've been long encouraged to keep our devices�*s software up to date but there are now questions as to how one faulty update could have brought so much chaos. vincent mcaviney, bbc news. earlier, i spoke with my colleague, simonjones, at heathrow airport, to get a sense of how disruptive this has been for passengers and crew. we were down at terminal two a short time ago, and i have to say it is very busy. to be fair, it was always going to be a really busy day here at heathrow because it is the start of the school holidays for many families. but add into the mix hundreds of passengers who were not able to travel yesterday, who have turned up and are standing in queues, trying to find alternative flights. in some cases, that is proving challenging. the good news is that all of the it systems at

airports across the uk are now back up airports across the uk are now back up and running again. there are no more problem is on that front. the bad news is that because of the problems yesterday, some planes, pilots and cabin crew are not where they should be, and that means their ongoing issues of delays and cancellations today. it is an improving picture because the latest figures we have are that almost 7000 flights globally were cancelled yesterday. today, that figure stands at around 1500, but it has left many passengers wondering how they are going to get to where they need to be. i have spoken to a couple of women who were desperately trying to get back to germany. i was women who were desperately trying to get back to germany.— get back to germany. i was trying to fl from get back to germany. i was trying to fly from canada _ get back to germany. i was trying to fly from canada to _ get back to germany. i was trying to fly from canada to hamburg, - get back to germany. i was trying to fly from canada to hamburg, but. get back to germany. i was trying to i fly from canada to hamburg, but my fi-ht fly from canada to hamburg, but my fight got _ fly from canada to hamburg, but my fight got cancelled while i was coming — fight got cancelled while i was coming off of my aeroplane. i have been _ coming off of my aeroplane. i have been stranded for around 24 hours by now _ been stranded for around 24 hours by now i_ been stranded for around 24 hours by now i have _ been stranded for around 24 hours by

i've had a lot of people say to me in the last 24 hours that they think they might start carrying cash again so that they can pay for things in the shops if the payment system goes down. i have seen people in the newsroom using more pens and paper than i've seen in quite a while. people mentally thinking, maybe i will keep a back—up of that important note i want to remember in case when i go back to my computer i have the blue screen of death and can't get back into it. how long that legacy will last, i don't know. something big like this happens and everyone thinks they will change their behaviour, then the following week they have forgotten all about it. we will have to see. i think there are also big questions to be asked of the giants — microsoft is very clear that it was not at fault here, it was not an update issued by it, but the question is, how did it slip through its safety net? there is a dilemma, because in orderfor antivirus software to be effective, it has to be in your machine at a granular level to find any potential malware that is sneaking about, hidden away.

that also means it has got to have this sort of access that leaves you potentially vulnerable if the software itself misfires, as it has in the last 24 hours. the question then becomes whether people have reaffirmed theirfaith in technology because they think more technology would fix the problem, or whether they are backing away from it. you are suggesting there was a temporary backing away but really the march of technology, artificial intelligence, will and must go on. i don't think technology will go backwards. there was far too much money and power going into the big tech companies building and providing these tools. there are lots of people who depend on it and who are encouraged to depend on it for our everyday lives. the benefits and convenience are something that many people have accepted. we will also have to accept that the more we use it, the more these outages will affect us, the more we will notice them and the more catastrophic they could potentially be.

joe biden said he's "looking forward to getting back on the campaign trail next week" after isolating with covid. 0vernight, a senior democratic congressman, who described mr biden as a mentor and friend, said the president didn't seem to recognise him at a d—day event last month, prompting yet more calls for him to drop of out the race to be re—elected. here's our north america correspondent, peter bowes. the calls forjoe biden to get out of the presidential race are not letting up. in all, more than 30 democratic members of congress, including four senators, have said they don't think he can beat donald trump. seth moulton, a congressman from massachusetts, was one of the first to speak out after the president's disastrous debate performance. now he is elaborating on why he thinks his long—time mentor and friend should step down. joe biden, he says, used to greet him with a big wide grin

and say how glad he was to see the congressman. but last month at a small gathering in france, he said the president didn't seem to recognise him. he says the incident led him to the crushing realisation that joe biden would be unable to defeat donald trump in november. the president, who is currently recovering from covid, still rejects that conclusion. he insists he will be back on the campaign trail next week. peter bowes, bbc news. the authorities in china's shaanxi province say 11 people have died and more than 30 are missing following the partial collapse of a highway bridge. a statement by the provincial authority said the bridge in shangluo city collapsed on friday due to a sudden downpour and flash floods. rescue teams have recovered several vehicles that had fallen into the river. china's president, xijinping, has urged what he termed "all—out efforts" to find those still missing.

the government in bangladesh has imposed a nationwide curfew. and called on the army to help quell protests in which at least 67 people have been killed. students have been demanding that ministers scrap a quota system which reserves many public sector jobs for the relatives of veterans of the country's war of independence. the un has said violence against the protesters has been shocking and unacceptable. a spokeperson for the bagladesh police have said around 300 bangladeshi police officers were injured during friday's clashes with demonstrators in multiple locations around the capital, dhaka. let's speak to naomi hossain, a professor of development studies at the school of oriental and african studies. welcome to the programme. could you explain the background to these protests and why there is a divide over the legacy of the country's history? over the legacy of the country's histo ? . ~ over the legacy of the country's histo ? ., ,, i. over the legacy of the country's histo ? ., ,, ., over the legacy of the country's histo ? ., ., , history? thank you for covering this sto . as history? thank you for covering this story- as you _ history? thank you for covering this

is a curfew and a state of emergency. we don't know much about what is going on. but credible reports of over 100 deaths so far. the broader context is that after a period of successful development and economic growth bangladesh has had a cost of living crisis, 10% inflation, high levels of unemployment, and critically a lot of this is taking place in a flitting system that is increasingly authoritarian. the last two elections are not deemed to have been free or fair. trade unions, civil society groups and others have faced disappearances and threats of violence. the protests have escalated beyond a demand for quota reform and for accountability and justice. we are hearing demands for

today's sport with jane dougall. hello from the bbc sport centre. the leaders aren't due out for a little while yet but there might be better conditions for those who have started their third rounds of the open at royal troon. ben croucher is on the west coast of scotland to see who might profit on so—called moving day. 0ther other conditions slightly better today for those who have become? absolutely. what a difference a day makes will stop justin absolutely. what a difference a day makes will stopjustin rose, who was tied for second in the championship, said that friday was all about surviving. saturday could all about be thriving —— could be all about thriving. players were struggling to control their golf balls yesterday, but today is much calmer. the wind has died down and we have some drizzle in the air. the golfers won't buy that too much. i was on the course and our guide, we had some sunshine, the flags fluttering

on the greens much less than over the first couple of days. as we have seen already on saturday, the likes of adam scott, justin thomas have all been four under for their various stages of the third round. another challenging the top of the leaderboard —— none are challenging the top of the leaderboard, because they are out in a couple of hours' time. the leader is on seven under par, shane lowry. justin rose on five under par. he is 43 and says he needs to embrace the childhood dream to get his hand on a claretjug. just ten golfers under par. scottie scheffler, majorwinners just ten golfers under par. scottie scheffler, major winners this year. his driving and his r and play should be suited to links golf. we are respecting the rain to get a little bit heavier by the time the

leaders take to the course and a couple of hours' time. that could definitely shake things up a little bit. all of the action from the third round still to come. thank ou. the west indies are now leading england in the first innings of the third day at trent bridge. they started the day needing 65 runs, they've now passed their target and lead by 41. as they took the lead, a six from shamarjoseph hit the roof of trent bridge, sending a few tiles sliding down and hitting some of the fans below. they were fine! west indies are all out for 457. a lead of 41 as they go into the second innings. helen glover is having an incredibly busy year. she's also working hard to try and claim the top spot when she competes in the olympic games in paris. the two—time 0lympic rowing champion is supported by husband and tv nature presenter steve backshall, who is passionate about using sport to promote environmental change.

she admits herfamily are a big inspiration to her as she prepares to compete. 0ur reporter, sarah dawkins, caught up with the pair. i took a year out after tokyo and was considering and what i pictured their three faces on the finish line, that did it for me and that was the reason.— line, that did it for me and that was the reason. steve, we were talkin: was the reason. steve, we were talking about — was the reason. steve, we were talking about sustainability - was the reason. steve, we were talking about sustainability and | was the reason. steve, we were i talking about sustainability and the key climate issues around these games. you are passionate about the environment. why did you want to take part in this cycle and should we be worried about the impact round heat and climate change? we we be worried about the impact round heat and climate change?— heat and climate change? we should be worried. one _ heat and climate change? we should be worried. one thing _ heat and climate change? we should be worried. one thing that _ heat and climate change? we should be worried. one thing that sport - heat and climate change? we should be worried. one thing that sport can | be worried. one thing that sport can do well— be worried. one thing that sport can do well is _ be worried. one thing that sport can do well is amplify messages. british rowing _ do well is amplify messages. british rowing have done an extra ordinary 'ob rowing have done an extra ordinary job in— rowing have done an extra ordinary job in recent — rowing have done an extra ordinary job in recent years. we have spoken about— job in recent years. we have spoken about water— job in recent years. we have spoken about water quality and how important water is. let's do the same _ important water is. let's do the same for— important water is. let's do the same for climate change. sport can talk to— same for climate change. sport can talk to people across boundaries, two people from different areas. it

the person who did that, knees knocking — the person who did that, knees knocking away for the rest of his life. that's disgusting. we had police vans upside — up the road, further up, turned upside down, police cars and police vans. ijust think it's... they've no respect. 24 hours ago, there was a burnt—out double—decker bus ride here. things have calmed down a lot since then and the police and the local residents in the area will be hoping that continues for the rest of the weekend. thursday night's violence happened after the police and social services removed children from a family. the romanian and roma community became angry with the authorities. last night, they gathered peacefully in solidarity with the family after this call for calm. continue to have faith and to stand together and to avoid any disruption and tension and not to do any damages because there's already a big damage and we don't want to continue to bring more suffering. we want to show the family that we are next to them and they need us to be in peace with them.

senior police met the government to discuss community tension and the impact social media had on events. many people will have seen on the social media some of the really shocking scenes of audacious criminality, and that's why it's really important that those individuals face the full force of the law. footage of the chaos will continue to be shared on social media — a reminder of what happened here. residents and the police willjust hope it doesn't spark more trouble. jim connolly, bbc news, leeds. 0ur reporter, jessica lane, gave us the latest from the scene earlier today. a lot quieter and calmer than we have seen in those images since thursday night. we have had a team of street cleaners coming into this area this morning. you can see they have done a greatjob of tidying up. that is because around 100 members

of the roma community were in this area last night. they came here peacefully in solidarity with the family, who we believe to be at the centre of what happened that sparked all of the unrest on thursday night but the people who came here last night were peaceful. but the area did need a fair bit of tidying up. you can see there is still a large police presence in this area. we have had four or five police vans full of officers coming here. they told us they are here for reassurance and so far they have not had any further trouble overnight all this morning. they, as well as the people who live and work here, hope that continues. but police say they are looking at what happened on thursday night and friday morning, and they have already made some arrests and will keep pressuring people who were involved in the disorder, and they will make further arrests in the coming days. thousands of workers at disneyland in california have voted in favour of strike action in a dispute about pay. employees say they can't afford to live

in the expensive neighbourhoods near the amusement park. disney says it is committed to reaching a deal. the bbc�*s regan morris reports from california. it is business as usual here outside disney headquarters, and that is what the executives inside want the public to know as well. disneyland is open, business as usual. the strike authorisation vote does not mean a strike is imminent. both sides say that. disney has said in a statement that it is committed to reaching a deal with its cast members, and that's what the workers at disneyland are called by the company — if you work there, you're a pirate, a princess or a plumber, you are a cast member. there is a performance involved in creating the magic of disney. that is what the workers say. they say, "we make the magic, you make the money," and they would like some more of it. i was at a protest there earlier this week where i heard harrowing stories from disney workers about how difficult it is to make ends meet living in southern california and trying to get to the park, trying

to find a place to live within commuting distance of the park. they make about $20 an hour, which seems like good money, but if you are on your own living in southern california or trying to raise a family, that is not a lot of money at all. it is difficult. the cost of living is astronomical. they are hoping for some more money. i spoke to some people who were living in their cars or in cheap motels around the park, and that is something they say has to stop. they say disneyland is a place where dreams do come true, so maybe they will for these workers when they resume contract negotiations next week. that strike authorisation vote should give them a little bit more leverage anyway. stay with us here on bbc news.

hello. many of us are feeling the humidity today. it is still quite warm, but the sunshine will soon give way to rain clouds in many parts of country if it doesn't reach you already. the weather front is currently across western parts of the uk. you can see the rain earlier on on the radar here across western parts of scotland, moving through ireland, reaching western wales and also south—western england. to the east, we have had a dry weather. in fact, a beautiful start to the day. quite murky with all of the humidity, but i think we will keep the dry weather the further east you are for pretty much the rest of the day. let's zoom into the details, then. this is what it looks like in then. this is what it looks like in the short—term. in south—western parts, extensive cloud, outbreaks of rain, some heavy, temperatures hovering around 1920 celsius. similarfor wales and the irish sea. hazy skies further east, dry for many at this stage, but some isolated storms, so you may have

seen those lightning symbols there. some sunshine for eastern parts of scotland, but pressure conditions coming in after that cool front. 15 there in stornoway. a relatively fresh day in the west, but in the east, the air is still coming from the south with a lot of humility. 17 or 18 degrees in london and norwich first thing, not so hot and humid to the west. this weather front moves in and drifts in some kyle turner bricks of rain to northern ireland. just the shower and as interpreters in the high teens and low 20s. how about early next week? weather fronts are moving in that we have a ridge of high pressure meaning more settled conditions who stop any

weather fronts will be generally weak and brushing north—western parts of the uk. a bit of a mixed bag depending on where you are, but i think overall it is actually not looking bad at all. those temperatures are around the average for the time of year. that is it from me. goodbye.

this is bbc news. the headlines... the global tech outage is over but the effects are being felt at airports around the world, with more than 1,500 flight cancellations today. almost 7,000 flights were cancelled worldwide on friday. the cybersecurity firm behind the major glitch has apologised. a congressman hasjoined more than 30 democrats publicly calling on president biden

to drop his re—election ambitions, claiming the 81—year—old didn't recognise him at d—day commemorations in normandy despite their long friendship. there've been sporadic clashes in the bangladeshi capital, dhaka, as the military enforces a national curfew to quell anti—government protests which have seen more than 100 deaths in recent days. and disneyland workers have voted in favour of going on strike, saying they are not paid enough at the �*happiest place on earth'. disney insists it's committed to reaching a deal, with talks resuming monday. now on bbc news, the child rescue con. it was probably one of our highlights for the year, rescuing her, and it was really a needle in a haystack type of situation. a one—day—old baby that our awesome team rescued just before being trafficked. millions of children are victims of trafficking around the world. it could have gone both ways,

but we did manage to spot her
