cancellations and delays — after a globalfailure of the company's computer systems. planes have been grounded at many airports worldwide. all ba flights from london heathrow and gatwick have been cancelled for the rest of today. the airline says delays and disruption may continue into tomorrow. it has also apologised and said it's "working to resolve the problem," although it had found "no evidence that it's a cyberattack". in the past over british airways ceo has said a power supply issue was to blame. the gmb union said the meltdown could have been avoided if the company hadn't outsourced hundreds of itjobs to india. a ba spokesperson has refuted the claim and has said that they "would never compromise the integrity and security of their it systems." our business correspondent, joe lynam, has more.

this is what happens when there is a major it failure. queues were snaking out of the door at terminal 5 at heathrow airport for thousands of ba passengers. the long bank holiday didn't start very well for these people. people have been standing in the queues for up to 120 minutes in some cases. the queue stretches from the check—in desks all the way out to the back of the terminal and down in front of the terminal where all the taxis deliver people. and many passengers contacted the bbc with their experiences. travelling with my 80—year—old grandma. it is her birthday. we have not been offered chairs, water, vouchers, nothing. by this afternoon, the disruption was such that ba took the unusual step of cancelling all flights from heathrow and

gatwick airports. this is the queue for customers leaving the terminal. and there have been reports of severe delays for ba flights around the world. this isjfk in new york. and this is rome. ba said it had experienced an it outage which had affected the airline's global network. it said it was working to resolve the problem and apologised to customers. a senior figure in the aviation industry said an it failure of this magnitude was extraordinary and rarely seen. he added ba had taken the right step to stop all departures. for some ba passengers though, the long bank holiday weekend could be very long indeed. joe lynam, bbc news. on the line is the architect and tv presenter, george clarke. he's at heathrow airport

how are things? i have just left terminal five how are things? i have just left terminalfive and how are things? i have just left terminal five and am how are things? i have just left terminalfive and am in a taxi on the way home but i was supposed to be an ibf are now sitting by the pool be an ibf are now sitting by the pool. that was one of the most turbulent and badly organised days i have ever experienced in britain and iam have ever experienced in britain and i am slightly embarrassed by it. i'd realise when such a major it infrastructure goes wrong that will cause massive repercussions, i get that and i do not think anyone had problems about the flights being cancelled, it's one of those things, by the lack of communication all day. there was a single —— not one single tannoy announcement all day. we did not have a single member of

staff co m e we did not have a single member of staff come up to us at any point to explain what was going on, i think a lot of staff did not know what to do, it was not passed down to them from above. i got there at 9:30am and the system was down and the struggle to check us in. and if they can check us in and get a boarding pass hoping you have flight times and all the other technical details. one of the crew told me they did not have a flight plan so that is why they could not take off. on a simple level you had the pilots, the plane, the passengers but theyjust did not have the information for us to take off safely and obviously safety is paramount, i get that. but lack of communication and lack of any information from any staff at any point of the day was a woeful, to say the least. would you fly ba again? it was

obviously a massive mistake but i would fly ba again. everyone makes m ista kes would fly ba again. everyone makes mistakes acclaimed and you have to hold your hand up and say today was a major mistake. —— everywhere makes mistake at times. when you think about the systems in place when you checkin about the systems in place when you check in and go through security and passport control and all those procedures are well organised for the safety of passengers and it is brilliant, but when it goes wrong, i just think the level of customer service and communication was terrible. i did not even know my flight had terrible. i did not even know my flight had been cancelled at any point today. any time i found out was from the bbc news website. i found out more from the bbc news website today than i did from being in the terminal and in that awful situation. that is ridiculous. not at any point that it say on any display board anywhere our flight

was cancelled. even when i left the building tonight it said please wait. we were moving from gate to get and wait. we were moving from gate to getand a wait. we were moving from gate to get and a lot of the pilots did not even know which gets to go to, that's how chaotic it was. i have never seen anything like it in my life. it was really bad and i was quite embarrassed by it. i thought it would be an awful lot better and i felt sorry for the staff because they did not have the information either. this was coming from above, i think. george clark, thank you for sharing your story with us. on the line we have a woman trying to travel to disneyland in orlando from gatwick earlier today. where are you, sarah? and your home, that you know what is going on?” are you, sarah? and your home, that you know what is going on? i am currently outside my sister's flat in london because my dad very kindly

and luckily managed to book us a new flight with and luckily managed to book us a new flight with virgin for tomorrow morning so we flight with virgin for tomorrow morning so we can flight with virgin for tomorrow morning so we can get the kids to orlando for their trip of a lifetime. because otherwise we would not have been able to even leave gatwick, our cars are at gatwick, there was no information at all, it was hideous. the lack of communication was disgraceful, disgusting. we keep hearing about not being communicated with by ba staff. you are going to make that trip, albeit with a different airline. you know where your cases are? luckily, we have our cases, they off—loaded them and we picked them up. but we arrived at gatwick at 8pm andi up. but we arrived at gatwick at 8pm and i have literallyjust now got out of the taxi —— 8am. and there has been no vouchers for food, out of the taxi —— 8am. and there has been no vouchers forfood, no communication, and there was ba

staff, there was about to ba staff we could see at gatwick. it was awful. sarah, thank you and i do hope you enjoy your trip to orlando. our business correspondent was sporting and he is worth me on said mel —— he was reporting. we've heard these stories and what is getting people more than anything is getting people more than anything is the lack of communication. how much damage will this have done to ba? the reputational damage could be notable because even i entered the journalistic field found it tough to get through to ba. their phone system by as well, it is an internet—based phone system so i could not even phoned them up on the 24 could not even phoned them up on the 2a hour media line. what we learned is when you do have a catastrophic

it failure it creates the house of cards affected because, let me give an example, when you arrive at your gates to board the plane and the computer system has crashed they cannot verify you are the same person who checked in went through the initial departure gates. then that the issue issued —— then the issue of your bags because if your bags... if the plane does not take off, the gate that takes off from this non—vacated and if it is not vacated the incoming flights from anywhere in the world cannot believe that country to arrive at that date because it does not know where it can park the planes. you can see the whole domino effect of having one major, catastrophic it failure which we now know was a major power source failure. it is a power issue. so somebody flicked the switch or... ? there are fallbacks worked ——

fallback systems, electricity substation is the size of a city in heathrow but it specifically hit british airway systems which have an unbelievable impact on the tyre computer network. thank you for now, joe. and we'll find out how this story — and many others — are covered in tomorrow's front pages at 10:30 and 11:30pm this evening my guests tonight are the deputy head of sport at the sun, martin lipton and the evening standard columnist, rosamund urwin. the change in the threat level follows significant progress by police in their investigation into the manchester bombing. officers have been targeting the network they believed supported the suicide bomber salman abedi. detectives and investigators have

spent most of the day at best property and moss side, to the south of manchester city centre. we have cctv of the moment they arrived just before they arrived at 7am, police officers knocked on the door in and went in to search the house. —— blasted the door in. the men away in ha ndcuffs blasted the door in. the men away in handcuffs and were presumably taken away for questioning but we have not had confirmation they actually made arrests at this at this address this morning. look what happens if we move on more than one hour later, we see an army bomb disposal team arriving because the police officers clearly fou nd arriving because the police officers clearly found something that cause them concerned and that caused a number of streets to be sealed off around this terrace and a number of homes evacuated and people were told to leave the property is to get back for their own safety. there was a large police cordoned in place while

the army team did its work in making sure everything he was safe. there has been other investigations across manchester today, two more arrest this morning to the north of manchester. there are now 11 men employed —— police custody being questioned. we got an update on the number of casualties still in hospital. there are 63 people still enjoyed being treated in hospital, at 20 of them are receiving critical ca re at 20 of them are receiving critical care which means they have serious injuries. —— 20 —— it is still taking time for people to fully understand and the police investigation is a rippling out further across manchester and beyond as investigators build a bigger picture of the network that must‘ve been involved in building the bomb and detonating that horrific attack

on manchester arena on monday night. the change comes on one of the busiest days of the year with many events being held across the country. extra police and security staff have been deployed at sporting events, music festivals and around manchester. this has become the focal point for those who wanted to come to pay tribute to those who lost their lives. we can see the ever growing number of flowers and balloons, people have been here fro —— says early morning and many are still here this evening. as they stop, reflect, look at the tributes to the pub rock. people from all over the uk each year. —— tributes are left here. there is a concert tonight, so

people coming from all over because this has affected the whole country. earlier today some of the families of some of the victims came here and also colleagues of the 43—year—old police officer who was off duty at the ariana grande a concert on monday night. she tragically lost her life. she was in the cheshire force and some of her colleagues came today to pay tribute to her. her partner was seriously injured her two children were also hurt. this is, of course, the 22 victims who died but there are those injured and are still in hospital. with the update you with that. 116 people treated in hospital since monday nights, 63 are still in hospital and

20 of them are in critical care. this is one of the busiest days of the year, the may bank holiday, big events all over the country, not least in manchester, extra police and security have been drafted in. my and security have been drafted in. my colleague reports. they're on hand for photos, but the armed police out on the streets are there to protect and reassure the crowds who've turned out for the bank holiday weekend. shoppers mixed with hen parties in manchester as the threat level was lowered. itjust made you feel much more secure be quite honest having that so, yes, i think only sort of five days after something critical‘s happened in manchester, to reduce it so quickly, there's still a lot of investigation going ahead. there is also the side that though that you trust the fact the investigation's shown that maybe it's not the threat that we thought so you could feel possibly a bit

comforted with that. increased security will be evident at 1300 events happening this weekend, including at wembley for the fa cup final between arsenal and chelsea. at the let's rock festival in shrewsbury, armed officers are mingling with gig—goers and every one of the 50,000 spectators at radio 1's big weekend in hull will be searched at least once. i got searched twice, once at the transport and once here. no—one minds, because it's all about the safety. i would personally rather wait the extra half hour and get checked. they've got to be there, haven't they, that's understandable. although the threat level‘s been reduced, the increased security will continue until midnight on monday. we made the decision that the resources we planned for this week's events will continue, so they'll still see the high level of police presence, some armed, some unarmed. once we are past the weekend, we are going to look forward to stepping down the extra resources we put in place over the last week. georgina callander was killed in the blast.

her mum was frantically trying to find her after the concert. today she spoke about the moment that she found her daughter. there she was on the stretcher and they were working doing resuscitation and getting her down the stairs and i was just screaming and shouting at her. i was rubbing her hands, rubbing hertummy, rubbing herface and all the images are so vivid now, i can see everything... for every victim, a harrowing story. so much loss, unimaginable grief. the pain of this tragedy is still raw. one of the victim's families came

here to the square today. they've released a team yellow balloons in tribute and they brought flowers. the crowd paid their respects, breaking into a round of applause as the family did so. let's return now to the disruption to ba passengers today following a major failure of its computer system. all flights to and from its two main london hubs, heathrow and gatwick, are currently cancelled. with me is ross brewer — an it analyst from the security company, lothythm. two weeks since we were discussing another it failure. what do you make

of this one? it is a wake-up call for the executives of all organisations are running critical national infrastructure. because we had the 12 weeks ago, in this case a power failure shows how reliant we are on these technologies. what does power failure are on these technologies. what does powerfailure mean are on these technologies. what does power failure mean to you? epically there will be a data centre —— data centre holding critical information and typically organisations plan ahead for this, they have secondary data centre centres which will be interesting to see what comes of this but it shows, in terms of organisations being able to see what is happening with the infrastructure and track down these problems quickly, better monitoring, better response, more rapid response and more preparedness and on these issues. in simplistic terms, i would think a generator would kick in, a back—up power source. is that not much happening? yes. so does that say to

you —— is that not meant to happen. what does that say to you about ba's system ? what does that say to you about ba's system? most organisations now have moved to a mixture of cloud —based technologies, some work through third parties so if you look at the technologies themselves, over the past ten years that is a more interconnectivity, your colleagues and talking about the fact you have got to get your ticket and then through baggage, customs, line up with your bag and if you are on the plane and the bag is not you cannot fly. so it is across the whole critical national infrastructure theseissues critical national infrastructure these issues are important. so these companies are so heavily reliant on these systems, what do you mean by a wake—up call? what needs to be done? is it money and

investment? there has been underinvestment in most critical national infrastructure and even with, from a cybercrime perspective, which this one does not... are we sure about that? that is an interesting question because even if it was those not obligation for the organisers this —— for the organisation to see it is that is when you are introducing a regulation specifically making organisations mandatorily disclose if they have had a data breach, they have 72 hours to do so and if they fail to do that or the governing body believes they have not done what they have to do that is a fine up what they have to do that is a fine up to li% of the turnover of 20 million euros. the chief executives in the executive team have typically deal with more business issues and often do not really know what is going on with it they need to start

paying attention. briefly, how long would it take to get this up i'm going again? is it a big problem to fix? clearly it has been all day but i would suggest organisations need to get much better visibility over their it and better visibility over their it and be able to identify problems very quickly and respond much faster. ross, thank you very much. nice to see you again. an elderly couple who were stabbed to death at their home in county armagh have been named. a relative found the bodies of michael and marjorie cawdery, who were both 83, in portadown yesterday. a ao—year—old man has been arrested and is still being questioned. the so—called islamic state group say their fighters were behind a shooting in central egypt yesterday. twenty—eight people were killed when masked gunmen opened fire on a bus taking a group of coptic christians to a monastery. the egyptian military has carried out airstrikes on militants in libya in retaliation. president trump has said he'll make a final decision

whether to maintain the us's support for the paris accord on combating climate change next week. he's among the leaders of the seven top industrial nations meeting at the g7 summit in italy for the final day of talks. there is a fault line must then the g-7 there is a fault line must then the g—7 on climate change. you have the sub grouping of the gi and they stand against the grouping of the gi. and gi containing just the usa. the six maintain their commitment to the climate change policy and donald trump has said he will reveal his final decision in one week. if the united states decide to either

withdraw from the paris climate change agreement reduce its commitments other countries may be tempted to follow, putting the nature of the paris climate change deal in question. radio 1's big weekend has held a minute's silence at the event to remember victims of the manchester bombing. the two—day festival kicked—off with an increased police presence following the atrocity at manchester arena. here's the moment radioi dj nick grimshaw took to the stage we have got backstage to show you thousands of people who have come out for radio one's big weekend. we think around 25,000 people are in the crowd today, amid concerns of safety in the wake of the attack in manchester and there were concerns as to whether radio one should go ahead. the organiser told me earlier

today why it was important for the festival to go ahead and also told us festival to go ahead and also told us they had lots of meetings were held with senior police officers and they took a lot of advice and the number one priority today was about safety. this is what he told me a short time ago. what we have seen todayis short time ago. what we have seen today is young people of hull and the surrounding area seeing me want to reflect the sadness and anger we feel but also, you know what, we are going to go out as normal and go out and have fun at the festival. so it was right for us to carry on and make sure we got the tone and the mood right and make sure obviously it was safe and secure for everyone. ben cooper talking to me a short time ago. how do people feel about

the extra security in place? with me is chief superintendent christine wilson. tell me about the operation today to ensure the safety of eve ryo ne today to ensure the safety of everyone here? since the terrible events in manchester we have been doing nothing but reviewing security to make sure this was safe and felt safe for the public and what you have seen some fantastic operations, slick searching and people are having a fantastic fantastic time. it is quite a large police presence today, exactly how many officers are out here? we have hundreds of police office rs out here? we have hundreds of police officers this week working and community support officers as well as the armed police and people and control rooms, saw hundreds are involved in the operation. we will have to leave the main operation as emile sande has taken to the stage. todayis

emile sande has taken to the stage. today is a date when people have come together and sean how much music can unite people can —— how people can come together and how music can unite people. at 3pm people came together for a minute's silence. let's find out how the weather is doing. phil, i hearthat was a lightning incident last night?|j suspect lightning incident last night?” suspect it is more than one. almost... there was nothing dull about the weather, it really sparked off. those storms in the south reached the north of england and have moved up into scotland and on the firth of forth. in the north—west there is cloud and rain which will carry on for most of the evening. thunderstorms and gradually pulling away into the north sea

leaving behind a fresher night than of late with temperatures widely still in double figures, not too many problems sleeping tonight, i think. they dry enough start mostly and then a new area of cloud and rain with potential for thunderstorms initially in the south—west and spreading through mid afternoon as things turned muggy again in the south—east. further north bright and dry mostly. through the evening and into monday, those areas of cloud, rain and storms drift ever further north and east it and the bank holiday into one of those. hello, this is bbc news. the headlines: travel chaos in britain's airports as british airways cancels all of its flights at heathrow
