democrat at a recent meeting. bangladesh rocked by unrest... with more than 100 people killed in anti—government protests. thousands of workers at disneyland in california have voted in favour of a strike about pay. "audacious criminality" — the uk's home secretary condemns violent disorder in leeds. hello. global computer systems in healthcare, banking and airlines are slowly coming back online after a digital outage disrupted networks in many countries. the crisis was caused by a faulty software update which affected microsoft windows systems. but it could be some time before

all the backlogs are cleared. while some airline services are beginning to return to normal after thousands of flights were cancelled, operators expect some delays and cancellations to persist through the weekend. and many businesses are now dealing with backlogs and missed orders that could take days to resolve. 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. vinny 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's just there's no signals. at crowdstrike, we monitor

trillions of cyber events... 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 caused to customers, to travellers, to anyone affected by this, including our companies. 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. the ceo of the anti—virus firm crowdstrike has apologised for the disruption that was caused, but there are now questions about how a routine update went so wrong. emma vardy sent this report from outside the company's headquarters in texas. there hasn't been a lot of visible activity here at the headquarters of crowdstrike, based in austin, texas. you can only imagine, though, what is going on inside. before today, crowdstrike had built a pretty strong reputation in a relatively short space of time for providing top it security solutions. it's operating in more than 100 countries worldwide, it's relied upon by so many different types of businesses and as well as it security, what crowdstrike also does is investigate hacks and do some detective work on the hackers that are behind

major cyber attacks. now, the chief executive officer of the company has said he's deeply sorry. he has been speaking on an american business news network today. but as for why the problems happened in what was supposed to be a pretty routine update, the answer to that still isn't clear but some experts have speculated that perhaps it was a lack of testing which led to some weaknesses slipping through. so, from now on, crowdstrike are going to clearly face some credibility problems. their stock price has already fallen and there are growing questions about why so many different businesses and public services are reliant upon one company behind it all. and there are growing questions, too, about what repercussions software firms like this should face when flaws cause major disruption. the widespread global impact of a single software glitch has given many a cause for concern.

our technology editor zoe kleinman has more on this. i think a lot more people are a lot more aware now of this tech infrastructure that's really become part of the backbone of so much of our everyday digital lives, and how catastrophic it can be when one tiny thing happens that knocks that system over. i think the lessons that we're going to look at going forward, number one, is resilience. you know, also known as having a plan b, i've had lots of people say to me in the last 2a hours, they're thinking that they might start carrying cash again so that they can pay for stuff in the shops if the payment system goes down. i've seen people around here in the newsroom using more pens and paper than i've seen in quite a while, you know, people sort of mentally thinking, maybe i'lljust keep a back—up of that important note that i want to remember, just in case, when i go back to my computer, i've got a blue screen of death and i can't get back into it. i mean, how long that legacy is going to last? i don't know, you know,

something big like this happens and everybody thinks they're going to change their behaviour. and then the following week they've forgotten all about it. we'll have to see. there are also, i think, big questions to be asked of of the giants. you know, 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 nets? and there's a dilemma here because antivirus software, in order to be effective, it's got to be in your machine at a really granular level so that it can find any potential malware that's sneaking about, hidden away. but that also means that it's got to have this sort of access that potentially leaves you vulnerable if the software in itself, as it has in the last 2a hours, misfires. the question then becomes, just briefly, whether people have reaffirmed their faith in technology because they think more technology would fix the problem or whether they're backing away from it. but what you're suggesting is really there's a temporary backing away. but really, the march of technology, artificial intelligence will and must go on.

i don't think technology is going to go backwards. i think there's far too much money and power going into the big tech companies that are building and providing these tools, and there are lots of people who depend on it and are encouraged to depend on it to live our everyday lives. you know, the benefits of it, the convenience of it is something that many people have accepted. but what we're also going to have to accept is that the more we use it, the more these outages are going to affect us, the more that we're going to notice them, and the more catastrophic they could potentially be. and we'll be hearing from a tech expert a little later in the programme — so do stay with us for that. meanwhile, president biden said he's "looking forward "to getting back on the campaign trail next week" after his isolation with covid. pressure mounted on the us president overnight, when a democratic congressman, who described mr biden as a mentor and friend, didn't seem to recognise him at a d—day event last month. 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. earlier i spoke to katie pruszynski, a political analyst and phd research student at the university of

sheffield's department of politics and international relations. the timing of biden�*s covid diagnosis has been incidental and allowing some of these democrat voices to come through. the juxtaposition between biden�*s ill health with covid and trump being able to campaign on the basis that he survived an assassination attempt is quite stark. you have got that visible presentation of these two men who are otherwise a similar age, to the american public. one is looking incredibly fragile, one now looks like he has defeated an assassination attempt. president biden may see this as an opportunity to regroup, have a rethink, and respond? he's going to want to. the trouble is that now you're starting to see very serious high profile democrats come forward and take that moment of pause in the proceedings to vocalise their thoughts about it. none of these people

want to seejoe biden drop out of the race for policy reasons. this is not the squad talking about him not being radical enough. this is very broad policy, a political problem, they don't that he can beat trump. he will struggle at this point to make the case that he is a strong enough and fit enough to not only beat trump but to then go on and do the demanding job of being president. you have got a 2—stage problem. can he beat trump? but then, do people believe he is strong enough to carry out the very rigorous demanding job of being president? realistically, there is less than three weeks to decide the answer to that question, if they would attempt any kind of smooth transition? this is the key question for democrats now. because they cannot afford, and they will not want, to have an ugly fight about who could possibly take joe biden�*s place in the ticket. every day that goes

by that they don't have a solid nominee on a back—up plan, or they don't know whetherjoe biden is staying in the race, it is a day that the republicans can focus on, and everyone is talking to is good for the democrat nominee. the time is ticking down now. for democrats behind—the—scenes, they will not only be trying to see if they can urgejoe biden to move himself out of the race, they won't want to wield a knife towards him, as it were, he is so well respected within the party, but at the same time they need to get this in order so that they can have a sense of transition that allows them time to campaign on issues and notjust on the person. the authorities in china's shaanxi province say eleven people have died and more than thirty 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. let's return to our top story — the digital outage that's disrupted systems around the world, and affected key infrastructure, including healthcare, banking and transport. let's speak to simonjones who's at heathrow airport. i have just been down at terminal two. it i have just been down at terminal two. it is i have just been down at terminal two. it is very i have just been down at terminal two. it is very busy i have just been down at terminal two. it is very busy there i have just been down at terminal two. it is very busy there this morning. the message i am getting from speaking to airports, heathrow and the other major airports in the uk, is that the systems are backed up uk, is that the systems are backed up and running again. there are no longer it problems. the big issue thatis longer it problems. the big issue that is facing people wanting to travel is, because of the

cancellation yesterday, around 350 flights in and out of the uk were grounded, that means today that some plane and cabin crews are not where they should be, that means some flights of the attack to be cancelled because people are simply not in the right place. if you add in the flights cancelled yesterday, that means you have thousands of people who have been unable to travel, get where they want to get, or unable to get back to the uk, perhaps they are on holiday. down in the terminal, very busy. we were speaking to a couple of women from germany whose flight was cancelled yesterday. they are on holiday here. now they are desperately trying to find another flight to get them back to germany. they were standing in a long queue seeing what arrangements they could make. some of them told me that they had trouble finding accommodation last night. some people were sleeping in the airport. what the airports themselves are saying, check before you set out,

because the knock—on effects of what happened yesterday are likely to be felt perhaps for another day or so, as the airline companies try to get things back on track. it is an interesting reflection, or insight, as to what might be happening in other industries. it is a very visual demonstration of that? absolutely. here in the uk we had all sorts of issues yesterday, not just transport, airports and rail companies affected, but there are some big issues particularly in england and we with gp surgeries and able to access their notes. also problems in other areas. itjust gives you a sense of how much we rely on computers and these operating systems. and when things go wrong they can go wrong in a very bad way. we see it in places like airports with the long queues. people desperate to either get away on holiday, or get back to where

they need to go. you see a knock—on effect also down at the port of dover. it was expected to be a busy day for travel with the start of the school holidays for many families. but they say today, because people were unable to fly yesterday, hundreds of people heading down to the port of dover, and try to get on ferries without booking. that will make a complicated situation, what was already going to be a very busy day, even more challenging. the advice as ever, just check before you set out, don't turn up if you haven't got a ticket. thank you. terminal two, heathrow airport. 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 bangladesh police have said around 300 bangladeshi police officers were injured during friday clashes with demonstrators in multiple locations around the capital dhaka. let's speak to maya tudor from the university of 0xford's blavatnik school of government. welcome to the programme. tell us more about the basis of these protests? protests ? the protests? the impetus for these protests, the recent bangladesh high court decision to reinstate civil service employment quotas for relatives of the country's freedom fighters. to understand why these courses are so contentious one has to understand the independence struggle for bangladesh is relatively recent. it was only in 1971. some scholars

called a genocide. the country gained independence. in the context of that time, quotas which reserved 30% of the civil service seats for those veterans were widely accepted as legitimate. today, however, that context feels very different. first of all, those jobs are incredibly stable and lucrative and prestigious. there are just a few hundred of them and almost half a million bangladeshis compete for thosejobs. in addition, the current government, the incumbent government, the incumbent government, the incumbent government, the prime minister is the daughter of the country's founding father. what that means is, her party's members benefit from these quarters. the context today feels, according to some of the students i have spoken with, that it effectively entrenches the incumbent deletes in positions of power.

underlying this is concern about the political backdrop. we had elections earlier this year. this country has been huge advances economically but there is concern about democracy and authoritarianism?— authoritarianism? absolutely. this is takin: authoritarianism? absolutely. this is taking place _ authoritarianism? absolutely. this is taking place against _ authoritarianism? absolutely. this is taking place against a _ authoritarianism? absolutely. this is taking place against a very - is taking place against a very different context. it is worth noting that the students did protest against these quarters in 2018. the government, which was the same government, which was the same government, then promised to get rid of these quarters. the high court reinstated them just now. but the context is different. the incumbent is strengthened today. many democracy organisations worry that bangladesh is becoming a one—party state. but the context is also different economically. in 2018, growth was around 8%. growth is

substantially down, and inflation is up, what that means for the everyday person on the streets, as they are much more concerned about their pocketbook than they were when these protests last emerged stop the final thing to note is that this is happening against a backdrop of multiple exposes of corruption in the incumbent governments, and that has intensified discontent with the incumbent government. thank you. a hard—line ukrainian nationalist party has blamed russia for killing one of its most prominent members. iryna farion was shot while walking through a street in the western city of lviv. she was a former mp for the svoboda party, and had achieved noteriety for insulting the country's russian—speakers. a statement by svoboda said that farion had been murdered on the orders of moscow. however, ukraine's interior ministry said it had "several versions" of who might be responsible.

now to news here in the uk — and police are continuing to search for people involved in violent disorder in leeds on thursday — in which a bus was set alight. five people have been arrested so far. the disturbances, in the harehills area of the city, began after social services removed children from a family there. jim connolly has more. violence and chaos, leaving residents scared, businesses forced to close and a whole lot of mess to clear up. we saw the police make several arrests, and they've promised more to come. it may have calmed down but it's left residents having to come to terms with what they witnessed outside their own homes. yeah, i was frightened and scared. scared to come down here, really, because you don't know what they're carrying or anything. that's disgusting. we had police vans upside — up road, further up,

turned upside down, police cars and police vans. ijust think it's — they've no respect. 2a hours ago, there was a burnt—out double—decker bus 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. 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. it's business as usual here outside disney headquarters, and that's what the executives inside want the public to know as well. disneyland is open. disneyland. 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's 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's a bit of a performance involved in creating the magic at disney, and that's what the workers say, they say, you know, 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, you know, 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 is seems like good money. but if you're on your own living in southern california or trying to raise a family, that's not a lot of money at all. it's difficult. the cost of living is astronomical, so they're hoping for some more money. um, i spoke to some people who were living in their cars or in cheap motels around the park, and that's something they say that that has to stop.

but 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. labour's welsh executive will meet today to decide the timetable for electing a new party leader. vaughan gething resigned from the job — and as first minister — on tuesday, after four members of his cabinet quit. stay with us here on bbc news.

some rain at times. rain across south—west scotland and northern ireland. heavy bursts in south—west england and wales. the best of any early—morning brightness, even some sunshine, is out towards the east. a beautiful started east anglia. lots of sunshine coming through. you mightjust cling on to the sunshine as we go to the day but for many of the clouds will arrive and continue to push its way steadily east. for east of scotland and central and eastern england it will still feel quite warm and humid, and that could trigger a few sharp thundery downpours. there could be as much as an inch of rain. that will impact the feel of the weather. 19 celsius in plymouth. 2a, 25 in london. highest values of 27 in east anglia,

if we keep that sunshine. there could be some sharp downpours. rain and the north west of england. that train gradually easing out of northern ireland and the end of the afternoon. the west east divide continues across scotland. as we go through the night, the rain will drift north and east. heavy bursts for a time. a legacy of cloud across england and. not that much in the way of rain here. it will stay relatively mild and muddy through the night. 0vernight lows into the mid to high teens. we could start with a grey note, on the whole sunday will be relatively quiet day, with some sunny spells, alliterative rain in northern ireland, a few isis showers elsewhere. temperature is peaking at 23 celsius. into the early half of the week ahead, we will see one weather fronts leading through on monday, a ridge of high

pressure building, then another weather front waiting in the wings. we are back to the story that we have seen throughout the summer so far. no two days the same. there will be some showers, some sunshine at times, and again we keep that fresh feel.

this is bbc news, the headlines... banks, hospitals and airlines hit by a global it outage are slowly

getting back online today but there are warnings of continued flight delays and cancellations as computers are rebooted. more than 5,000 flights were cancelled globally on friday. a democratic congressman has written in a us newspaper claiming joe biden didn't recognise him at d—day commemorations in normandy — despite their long friendship. soldiers have been called onto the streets of bangladesh after a day of deadly clashes between student demonstrators and police. authorities say 300 police were injured. and disneyland workers in california have voted in favour of going on strike amid complaints about low wages and intimidation by managers. they say they can't afford to live in expensive neighbourhoods near the park. disney has insisted it's committed to reaching a deal. more now on the digital outage that's disrupted
