to world news today. british airways passengers around the world are facing flight 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" —— "working to resolve the problem" although it had found "no evidence that it's a cyberattack". the british airways ceo, alex cruz, has said that a ‘power supply issue‘ was to blame. 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. we've just literally just now been told that nothing's happening, no flights until 6 o'clock. prior to that, we hadn't been told very much at all, there were no tannoy announcements whatsoever. travelling with my 80—year—old grandma for her birthday, it's a celebration weekend, 13 of us going and we have heard nothing, haven't been offered any chairs, water, vouchers, nothing. by this afternoon, the disruption was such that ba took the unusual step of cancelling all flights after 6 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. simonjones is at heathrow airport for us. how things looking this? what people want from british airways is clarity. they wanted that today with many people turning up at the airport not knowing there was this problem. then they were told flight had this problem. then they were told flight had been cancelled until 6pm then later told there would be no ba flight then later told there would be no ba flight from here and gatwick for the rest of the day. what they want is to know when this will be fixed and whether they might be able to travel. i just spoke to whether they might be able to travel. ijust spoke to british airways who say they are working tirelessly to fix this problem but they could not give me any indication of a timescale. they are sailing they hope during the night flights will be able to take off on long haul services with a view to landing here in the morning and hoping the system will be running again by the morning. but at the moment that seems to be a hope rather than firm expectation. what the advise anyone due to travel is checked before you even set out to the airport because today we had the extraordinary measure of british airways telling people not to come here and for an airline that is very unusual. there were so many people at the terminal and such a very tricky indeed. no clarity yet on how much longer this chaos is going to continue. many thanks for that, simon. the g7 meeting in italy has concluded, with no indication from the united states, about whether it would commit to the paris climate agreement. within the past hour the us president donald trump spoke about the meeting to american troops, at sigonella air force base in sicily. it was a tremendously productive meeting were i strengthen american bonds. we have great bonds with other countries. some of our closest allies we concluded a truly historic week for our country. mr trump did not mention disagreements over the paris climate agreement. he's now on the way home — without giving the customary closing news conference. but he's tweeted that he will make his final decision on the paris accord next week. the german chancellor angela merkel said the uncertainty was very unsatisfactory. the entire discussion about climate a very difficult, if not to sit this fa ct a very difficult, if not to sit this fact is —— dissatisfying. we have a situation where we have six against one. until a few weeks ago we were thinking the usa would, and no discussion would be possible sol think there was progress and discussion. i also think the argument is violated by the six nations have been very strong and hope this will have helped president trump understand the importance of the agreement and its necessity for his own economy. a short time ago i spoke to james reynolds in sicily. i asked him about how disappointed the g7 leaders were about mr trump's refusal to accept the paris climate deal. you have this informal g6 on one side standing against the gi you have this informal g6 on one side standing against the g1 on the other side on climate change. the six say they support the climate change agreement and the one says he is still thinking. that matters because of the usa decides to withdraw or lower its responsibilities other countries may decide to do something similar, putting the deal into jeopardy. i spoke to the gents —— un secretary—general said the world would not end the usa unless the agreement but it would be a hammer blow. —— the blow. -- the usa blow. —— the usa left the agreement. blow. -- the usa left the agreement. no one expected this to be the warmest and most harmonious meeting of the g-7 but and most harmonious meeting of the g—7 but the reach some agreement on things that the? the final communique had more than a0 points, a lot of the language was very vague, the commitment to free trade. there was a very few specifics or are very few practical steps that might be taken that we are aware of. they repeated their condemnation of russia's actions in ukraine. it was those actions that led to russia to be kicked out of the g8. police say they have and that most of the group linked to salman abedi, the suicide bomber struck on monday. they made further arrests on saturday and said they now have a greater understand how the bomb was made. we can show you cctv when they arrived this morning, they bashed the door and went into search what was inside. they brought out two men who were taken away in handcuffs and put ina who were taken away in handcuffs and put in a police van and presumably taken for questioning but we have not had confirmation they actually made arrests here at this address this morning. look what happens if we move on more than an hour later and we see an army bomb disposal tea m and we see an army bomb disposal team arriving because the police clueless and something that cause concern which caused a number of streets to be sealed off —— the police found something that caused concern and a number of homes were evacuated. there was a large police caught them in place while the bomb disposal team did its work in making sure everything he was safe. there has been other investigations going on across manchester today with two more arrests to the north of the city which means there are now 11 men in police custody being questioned. we got an update also on number of casualties still being treated in hospital after monday's attack. 63 people still injured, being treated in hospital and 20 of them are receiving critical care which means they have got serious injuries. still, the impact on monday's pact being felt and taking time for people to fully understand and the police investigation is rippling out even further across manchester and b and as detectors built a bigger picture of the network that must have been involved in building this bomb and detonating that devastating attack on manchester arena on monday. with the investigation making rapid progress, uk authorities have lowered the threat level from critical to severe, meaning they believe another attack is no longer imminent. extra police have been deployed at many of the sports events, music festivals and other places where crowds have been gathering over the bank holiday weekend — including in central manchester — where well wishers have been coming to leave flowers and pay tribute to the 22 people killed in the attack. catriona renton has spent the day there. saint anne's square has become a focal point for people who want to pay tribute to those who lost their lives on monday night. you will see the carpet of flowers and balloons that has been growing all day as more and more people come here to remember, people have been here since early morning and people still here this evening. earlier the families of some of the victims came here and you could see them reading some of the tributes to their loved ones. among those were colleagues of elaine mciver, the off—duty police officer from the cheshire force who lost her life on monday evening. her colleagues came earlier today and also the family of georgina callender, who brought flowers and balloons to remember their daughter, and released 18 yellow balloons. she was a second—year student in lancashire. she tweeted before the ariana grande concert she was so excited to see the american star. these families obviously devastated to come here, looking for some comfort and support from the many people who have joined together across the city to support them. police in the american city of portland say two men were killed when they tried to stop a man racially abusing two teenage girls who appeared to be muslim. the incident happened on a commuter train on friday afternoon. the mother of one of the two girls told the local publication the 0regonian, that the attacker was saying that

british airways has claimed a power supply problem for the massive computerfailure supply problem for the massive computer failure that left thousands of passengers stranded worldwide. 0n that story, i spoke to the architect and tv presenter george clark. 0ne and tv presenter george clark. one of those at heathrow airport. we we re never one of those at heathrow airport. we were never called at any point by any were never called at any point by a ny staff were never called at any point by any staff the flight was cancelled, nor one was told that at all. all of our information came from the bbc website. we found at things from the bbc website faster than we were from staff at the terminal. i have never come across anything like it in my life. when you think how organised airport are on the procedures and processes we go through, security, passport checks and boarding passes checked, to not have any advice syste m checked, to not have any advice system in place and communication when the it system goes down is staggering. people were standing in brandon queues and no one was organising anyone. —— random queues. with me is a former spokesperson for heathrow airport. his current company advises companies on planning and infrastructure. pa rt planning and infrastructure. part of the frustration many of the stranded passengers had was they said they were not been kept informed. from your experience, when something like this happens what would have been going on behind the scenes? you would have a lot of people very busy right now in the office of british airways and the airport and what you will have is various calls over a day, another at 10pm, the traces of room that is active, trying to manage the situation dashed —— rice ‘s room. the problem ba has its everything is now connected. 0nce ba has its everything is now connected. once upon a tendon folie booking agent or who did not have a smart connecting your booking pass with everything else and once you ta ke with everything else and once you take one run up the ladder everything collapses. we have seen it before with other airlines and the main challenge british airways will now have is around the world with planes out of kilter and the system is not quite clear and it will take a few days to get back on its feet. a lot of passengers have been very frustrated about how it was handled. what could have been done better, if anything? from my own experience, getting drilled by you and your collea g u es getting drilled by you and your colleagues some years back, there is a degree to which bad news is never going to be taken well. everyone accepts it is difficult to communicate and you have had many reports of people complaining about not being told things directly but when the website is down and there is no way to e—mail or do that in twitter, as they have done, and the bbc is a way to communicate. my advice is to be honest, give people clarity where you can, but do not give any false expectations. i think the only thing i would have probably done differently today is not come out and say there might be flight after 6pm as they said earlier because you need to be clear and other help people do not come to the ill port or come monday, sunday, whatever, —— do not come to the airport. what whenever people say and do not come to the airport the public have a tendency to ignore that and go anyway. that is why it is -- that and go anyway. that is why it is —— and especially challenging situation where there is no way for people to go direct to consumers with their message. andrew, many thanks. now the latest from the world of sport. arsenal have won the fa cup, beating premier league champions chelsea 2—1 at wembley. aaron ramsey scored the winner in the closing stages. it's a record seventh fa cup win for arsenal manager arsene wenger, whose future at the club remains at the centre of much speculation. 0lly foster has been at wembley for us. the 136 fa cup final was a remarkable match in so many ways because we had a contentious goal, sending off and a result we were not expecting. alexis sanchez scored inside the first five minutes, did he handball it? yes, probably, but its dude. chelsea tried to get back in the second half, arsenal could have scored more in the first half. victor moses was sent off for chelsea, diego koestler still managed to equalise before aaron ramsey is a few minutes later scored the arsenal winger. a record 13th fa cup for arsenal, going ahead of manchester united. a record seventh for arsene wenger. all the questions now will be is that his final act as arsenal manager? what has been seen asa arsenal manager? what has been seen as a disappointing season, finishing outside the top four and the champions league football for them next season, but finishing it with this fantastic fa cup final victory against the champions, chelsea, and denying them the double. that will bea denying them the double. that will be a board meeting next week and arsene wenger says that is where we will finally find out where his future lies, but for now he says he just wants to enjoy it and i'm sure he will because this was a very special win for the gunners today. the german cup final is underway aswell. eintracht frankfurt taking on borussia dortmund who have made borussia dortmund and a miserable run borussia dortmund and a
