and grounding flights. a russian court sentences us reporter evan gershkovich to 16 years in a penal colony. donald trump gives his first speech since surviving an assassination attempt, accepting the republican party's nomination to run for president. and president zelensky arrives in downing street. he's the first foreign leader in nearly 30 years address the cabinet. returning to our ongoing coverage of the major it outage which has knocked businesses institutions offline. it's been caused by a faulty update released by the cybersecurity company, crowdstrike. the firm says a fix has been deployed. banks, supermarkets and other major organisations have reported computer issues disrupting services, some airlines have suspended flights.

airports worldwide are reporting delays for passengers, with several reverting to manual systems. where they are operating, passengers are being warned that it might take time to take—off because of backlogs with air traffic control. hospitals have also been affected, many elective operations have been cancelled. as have patient consultations. with doctors reporting they've had no access to patient records. media organisations have also been affected. here in the uk, sky news were off air. and here at the bbc — children's channel cbbc experienced problems broadcasting. our cyber correspondentjoe tidy gave this explaination of how the outages happened. some of the biggest companies in the world use crowdstrike.

and they are, they have a very popular piece of software called falcon, which is what we call an end—point protection piece of software. so it's like an antivirus software that you would download and you would have on your home computer. but there's one of those that's for big companies, and they put out what they hoped was an innocuous software update overnight, which would have made their product a little bit better. just a small update, the kind of like when we get on our phones, on our mobile phones, we get software updates and we update them, don't we? we do it automatically normally while we're sleeping and we don't even really notice. but this one, um, obviously had a flaw in it. there was something wrong with the code that was sent out to all of their customers. and bear in mind, if they've got 2a,000 customers around the world, that's 2a,000 medium, small, large enterprises. so that is potentially hundreds of thousands of end points of computers that receive this bad software update. and somehow on windows, when the software update was downloaded to a windows computer, which most of them would have been, it bricked the computer.

it broke the computer. it meant that you had this blue screen of death. and that's what people are dealing with all over the world. it managers are now trying to get what has just been released by crowdstrike, the correct antidote, if you like. that piece of software, they're trying to get that onto computers. but the problem that we have is that can't be done automatically over the internet. that has to be done with a manual process in most cases. so that is physical fingers on keyboards to try and try and solve the issue. you would imagine that the really large customers of crowdstrike, who have thousands, maybe tens of thousands of computers and servers on their networks, they've all been affected. you'd imagine they would take a long time. but what we're actually seeing is the opposite. i'm seeing that some of the companies that are bouncing back up are the largest ones. american airlines, for example. you'd imagine they've got thousands of computers across the entire world. they have bounced back pretty quickly. and i think what that is, is it points to the companies that are large and they've got lots of computers.

they're also well—funded and they've got it departments that are well—resourced. so i think they have bounced back and they are appearing to bounce back quicker than perhaps the small businesses or the medium—sized businesses that don't have that well—resourced it teams. they might even outsource their it to a third party. i think where we might see the real crunch points is when you have a large company that isn't well resourced in the it side. so they've got lots and lots of computers and not enough people to fix them. jake moore is a former cybercrime officer and police head of digital forensics. he says there was initial confusion that this might have been instigated by someone acting with intent. we hear so much about cyber attacks in the news, our data going missing, passwords being compromised. this isjust the time that we're living in. but what's come out of this? it's to do with updates, and all software needs to be updated

to keep us all secure from threat actors trying to to exploit any given vulnerability. but this update unfortunately looks like it had a major fault in it, which comes down to a testing issue, but that's the balance between speed of the update getting put out to all those computers, and of course, keeping everyone secure from any known or even unknown vulnerability. let me talk to you a little bit more now about, you know, the irony here, because crowdstrike, is it not a company that provides protection against, you know, in terms of cybersecurity? and it's that update that has really caused problems. yeah. and that is going to be a huge thorn in their side for many years. and we've seen issues like this hit many companies in the past. and unfortunately it's probably not going to be the last one. but we can take so much from this. they and other companies will of course learn that we need to do more testing in that balance period, when we have to look at those patches that need to be sent out, we need to make sure

that they are vitally secure and they're not going to do this again, because, of course, this blue screen of death that we're seeing around the world, it is a major problem. it then needs manual hands on the computers at this time to rectify it. and that's going to take days for people to get back up and running. so we don't want to see this again. i think if we learn from this, put more resources into that testing phase and we should see this hopefully mitigated. if you'd like to get minute—by—minute updates, you can head to the bbc news website. there you'll find our live page, which will bring you all the latest information. including this. we have heard from the chief executive who said the customers customers remain fully protected despite the ongoing outage. he said today was not a

security incident, customers remain fully protected, we are working on all impacted customers to ensure systems are back up and can deliver the services customers are counting on. he made a statement on twitter. he said earlier the issue had been fixed but it could be some time before all systems are back—up and running. president biden says the united states is "pushing hard" for the release ofjournalist evan gershkovich, adding "there's no question russia is wrongfully detaining" him. it comes as the wall streetjournal reporter was found guilty by a russia court of spying and sentenced him to 16 years in a high security penal colony. mr gershkovich had pleaded not guilty. his employer and the white house have described the closed—door trial as a sham. our russia editor steve rosenberg has more.

the wall streetjournal, us officials, evan gershkovich supporters, call this a sham — a bogus process, it's important to keep in mind. it was held behind closed doors, so that means the media weren't allowed in during the proceedings. um, uh, friends and family of mr gershkovich wouldn't have been allowed in, diplomats, foreign diplomats weren't allowed in. we were allowed in, in a group ofjournalists, for the verdict. we went into the courtroom and evan gershkovich was standing there in the metal and glass cage, which is known as the aquarium in russian courts. in came thejudge read the verdict — guilty. he was sentenced to 16 years in a high—security penal colony. now, i suspect that that's the kind of verdict and sentence that evan gershkovich would have expected from a russian court. certainly his supporters were expecting something like that. as i say, they say that this was a sham trial, but i think

we should pause for a momentjust to think about what just happened inside that courtroom. an american journalist convicted of espionage in russia and sentenced to 16 years in prison. that is unprecedented in modern russia. i can't remember anything like that happening at all. and now i think attention will turn to whether there is going to be, or whether there has been some deal between russia and the united states on a prisoner exchange, a prisoner swap. there's been a lot of speculation about this. nothing confirmed, but we know because russian officials have said it openly, that they would be open to doing some kind of a deal on a prisoner exchange. we know that discussions have been going on for months now between russia and the united states on some kind of possible deal. and we know, despite the fact that the court behind me has convicted mr gershkovich of espionage and given the 16—year sentence, we know that russia views jailed americans as bargaining chips as some kind of currency to trade for russians jailed abroad. so i think attention

will turn to that. and whether some agreement has been or can be reached between moscow and washington, that would enable evan gershkovich to to go home. anton trioanovski is the new york times moscow bureau chief. he's worked with evan gershkovich in moscow, and has been a friend. on the one hand, this was completely expected. we knew these types of trials in russia pretty much always end in a guilty verdict, and we knew he was going to get close to the maximum of 20 years in prison that he was facing. so it was very much expected. but then if you pause to think about it, it's really such a travesty and such an assault on press freedom and onjournalism and even

just on common sense, because it's so clear that evan was simply doing his job when he was working in russia and arrested last year. how is he? well, you know, it's possible to exchange letters with him which i have done over the last year—plus since his arrest. and i can say that, you know, he's been incredibly strong. i think he understands, has understood throughout this process, what a serious situation this is. but he's kept his hopes up. he's kept his spirits up. he's kept the spirits up of those close to him on the outside who are so worried about him. um, and, you know, we can only hope at this point that it sometime soon, this, this terrible ordeal will will come to an end. but as steve said, we can really

only speculate about that right now. it is speculation, but, you know, is there, do you think, some hope amongst his friends and supporters that there could be some sort of deal? that's the most realistic way, unfortunately, that that evan can get out of prison is, is through some sort of prisoner swap. that's how vladimir putin and the russian government have operated in recent years in terms of other imprisoned americans. at the same time, you know, he's should not be in prison. he is completely innocent. he was just doing his job. anton trioanovski the new york times moscow bureau chief. donald trump has given his first speech since surviving an assassination attempt at the weekend, saying god was on his side. he was speaking at the republican national convention as he formally accepted the party's nomination to run for president once again. earlier, we werejoined by shannon felton spence in boston, who is the political strategist at harvard university's think—tank the belfer center.

she shared her reaction to the former president's speech. well, last night was quite interesting, because it was the final night of the republican national convention, which has had a unique tone in trump world the entire week. it has been sort of a more unifying message. um, they've had a lot of speakers that wouldn't normally be on the stage at the republican national convention, like the president of the teamsters, which is our biggest trade union. um, and so it's been sort of different from past trump rallies or conventions. but then last night, he sort of started out that way. he talked about the assassination attempt, and he was very emotional, and he was raspy, and it looked like that speech was going in that direction. and then at about an hour in, it turned back into a typical a typical trump rally. so, you know, it's yet to be seen sort of what the messaging is going to be going forward. but what we do know is that this is the third time the republican party has nominated donald trump as their presidential candidate. and the transformation is complete.

there are no longer republicans out there that are never trumpers. if they're never trumpers, they're not republicans any more. aso this is a party that has been completely unified under one man, and that's donald trump. around the world and across the uk, this is bbc news.

ukraine's president volodymr zelensky has become the first foreign leader to address the british cabinet in person in almost three decades. he asked senior ministers to lift restrictions that stop the ukrainian

keir starmer welcomed to downing street the first official visitor from overseas since he became prime minister. it's no coincidence that this was president zelensky. he's been given the rare honour of addressing the british cabinet. are you getting the support you need, president zelensky? applause. during the election period, the labour leader talked a lot about change. today, he wanted to emphasise that a change of government did not mean a change of policy towards ukraine. we will stand with you and the people of ukraine for as long as it may take. and we back that up, obviously, with £3 billion of military support each year. that's a very important commitment. we will speed up our delivery of vital aid and equipment. we have had the chance to discuss that this morning. president zelensky thanked britain for its steadfast support, but he also had an ask — he wanted the uk to persuade the us in particular to allow western—supplied weapons to be fired deep into russia. we have proven that we can stop any russian attempt to expand the war, if the restrictions on using western weapons against russian military are lifted. once we can strike further thanjust nearthe border, including russian military airfields.

the last foreign leader to address the cabinet face—to—face was bill clinton back in 1997, and a labour government had just been elected then, but the world felt very different. people back in the �*90s talked about a peace dividend and the end of the cold war. today's meeting talked about ramping up weaponry and providing more ammunition. the government also said it would take action against what's been described as russia's shadow fleet. these are oil tankers sailing under flags of convenience, carrying sanctions—busting cargo. the previous government identified some of these vessels, the new government has identified more and will ban them from british ports. but it's unlikely the prospect of a trump presidency didn't come up in discussions. in his bbc interview last night, president zelensky was asked how he would deal with the potentially less supportive us administration. for us, we have to work

with the united states. and if a new team will come, we have to work with them. the ukrainian president leaves with the support of the fourth british prime minister that he is known since the conflict began. he said he himself would be willing to stand down when the war ends. that may still be some way off. iain watson, bbc news, westminster. let's get more now on the it outage which has caused chaos across the world. the firm behind it, crowdstrike a cybersecurity firm, in the last few minutes we have a statement from its chief executive. i want to read it to you. it is on twitter. it says today was not a security or cyber

incident. customers remain fully protected. we understand the gravity of the situation and are deeply sorry for the inconvenience and disruption. we are working with impacted customers to ensure systems are back—up and they can deliver the services. the issue has been identified and affixed deployed. there was an issue with a falcon update. he goes on to let people know that if you want an update they can go onto the website. to give you context into the impact of what has happened, we have heard now over 3300 flights have been cancelled around the world. we're not sure how many of these were directly because the crowdstrike outage but we know it makes about 3% of all the scheduled flights. so many of large airports around the world. the

damage could go on. we have heard in the hour that workers might experience a delay in their pay following the outage. that is according to the body which represents payroll providers. the global payroll association said the outage could have serious implications for businesses across the uk, particularly those who process payroll weekly. she said it might delay pay for employees. finally, crowdstrike is the company we talked about being behind the outage. its shares traded on the nasdaq stock market are down 15% last time i checked. 0ver1 billion, $12.5 billion wiped off the value. plenty more on that story on the bbc website where you are. let's bring you back to the uk,

where police have made "several arrests" over a major disturbance in leeds that saw a police car overturned and a double—decker bus set alight. west yorkshire police battled the "serious disorder incident" in the harehills estate as officers faced a barrage of bricks and other objects thrown from a large crowd that gathered in the street on thursday night. craig nicholls from the west yorkshire police federation has been speaking about what happened last night. what i will say is there are not enough police numbers. neighbourhood policing is an amazing tool to have when you have those numbers that are available. but at this moment in time, we just simply don't have enough police officers. we need at least double or triple what the previous government have given us to ensure that this community and the wider communities are safe within west yorkshire. my members will do that, without a doubt, without a thought in my mind. they will put themselves first and foremost for the communities that they serve.

0ur correspondent thomas magill is in leeds. it all kicked off after 5pm last night when west yorkshire police were called by the children's social care department after social workers called them because they were met with hostility regarding a child protection matter. now, after that, violence started here in the streets. a double decker bus was attacked, as were a number of other incidents took place. bricks were thrown and other small fires were started, and then a west yorkshire police car was overturned right here in the middle of haleshill, as you say. well, the clean up, as you can see now, is well underway. that carcase from the burnt out double decker bus is removed. it's gone. it's on the back of a low loader down there. and then street cleaners now are using water and brushes to damp

and dampen down the smoulders and the last remaining bits of debris from where that bus finally settled to burn itself out last night. but it has caused a lot of tension in the area and a lot of concern in the area as well. as you said, west yorkshire police have made a number of arrests and they say that more arrests could follow because a major investigation has been launched and they will be reviewing cctv footage in order to identify those people who were involved in last night's violence. now, i've been speaking all day to people within the community and also local community leaders as well. they have been calling from for calm. but there is fear here. there's anger. and it does remain tense, despite the fact that the number of police in the area has significantly gone down from earlier today, hoping to sort of quail that tension more of the family. we understand from people here that the family involved was from the roma community, but that has not been confirmed by any officials yet here or within from the west yorkshire police. so for now the area is quiet other than the noise of the street cleaners, and there's been a call for calm from local community leaders.

we understand from people here that the family involved was from the roma community, but that has not been confirmed by any officials yet here or within from the west yorkshire police. so for now the area is quiet other than the noise of the street cleaners, and there's been a call for calm from local community leaders. some breaking news from america. with regards to the presidential campaign. anotherfour democrats campaign. another four democrats have campaign. anotherfour democrats have apparently called on president biden to end his campaign for re—election. they issued their appeal after is after mr biden�*s team said he would return to campaigning. he is isolating after testing positive for congress. they said it was jeopardising what should

be a winning campaign. we also heard earlierfrom a be a winning campaign. we also heard earlier from a democratic us senator, us senator martin heinrich who called on mr biden to withdraw from the campaign in a statement. it remains with the fact that there is mounting pressure on president biden. we heard earlierfrom his campaign chief who insisted he was the best person to take on donald trump. there is no sign from the president that he is willing to step aside in anyway, despite the calls from these top democratic leaders for him to stand aside as the party nominee. we heard earlierfrom his re—election campaign chair. absolutely the president

hello. today is bringing some of the hottest weather of the year so far in many parts of the uk. the sun was certainly shining earlier on for this weather watcher in surbiton to the southwest of london, but it hasn't been like that everywhere. this was the scene on the western side of scotland, with a lot of mist and murk and low clouds. these northern and western parts of the uk are generally seeing more in the way of cloud. we also have this frontal system approaching that will bring some outbreaks of rain, the best of the sunshine across parts of england and wales, away from these western coasts, and where we see the best of the sunshine, those temperatures climbing into the low 30s celsius for some, even northeast scotland, with a little bit of sunshine not doing too badly, up to around 25 along the moray coast, and quite a humid feel out there as well. now through this evening and tonight, that weather front i showed you will start to make its move, bringing outbreaks of rain into northern ireland, western scotland, eventually into southwest wales

and the southwest of england. ahead of that largely dry and pretty warm and humid overnight. lows 12 to 17 degrees. now, as we head into tomorrow, central and eastern parts of england should hold on to some spells of sunshine, albeit with some sharp showers and thunderstorms popping up through the afternoon. but out towards the west we will see these outbreaks of heavy rain pushing in getting into the channel islands, moving across the southwest of england and wales. but where we do hold on to a little bit of sunshine across eastern england. yes, we could see the odd thunderstorm, but temperatures could again get to 2627 degrees. rain spreading into northwest england, northern ireland and the western side of scotland, eastern scotland perhaps holding on to some sunshine, lifting those temperatures into the low 20s and still feeling quite humid. even where you have the cloud and the rain, and that wet weather will tend to slide its way eastwards, fragmenting a little as we head through saturday night. and behind that area of wet weather. behind this weather front, we change the feel of things. we will change to fresher air pushing in from the atlantic, so it is going to feel cooler and fresher for the second half of the weekend. now the weather itself on sunday actually not looking too bad. rain lingering for a time across shetland. then we will see some spells of sunshine, but i think a fair amount of cloud rolling

in from the west that could produce just1 or 2 showers, but a considerably fresher feel. top temperatures 15 to 22 degrees.

live from london, this is bbc news. a major it outage cripples
