news. flutz cancellations and delays after a global failure over british airways computer system. planes have been grounded on many airports. flights cancelled for the rest of the day. the airline says delays and disruptions may continue into tomorrow. it has apologised saying it is working towards fixing the problem although it says there is evidence it is hacking at a system failure. this is what happens after a catastrophic it failure, thousands of ba passengers starting their long bank holiday weekend. queues of people snaking out of the door at terminal 5 in heathrow. people have been standing in the queues for up to 70, 90, 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. many passengers contacted the bbc with their experiences. we've just literallyjust now been

told that nothing's happening, no flights till 6pm. 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. there's 13 of us going. we've had nothing. we haven't been offered any chairs, any water, any vouchers. nothing. by this afternoon, the disruption was such that ba took the highly unusual step of cancelling all flights from heathrow and gatwick airport. this is the queue of customers leaving the terminal. and there have been severe delays for ba flights around the world. this isjfk airport in new york. and fiumicino in rome. pa: british airways has cancelled all departures from heathrow and gatwick. customers were handed out leaflets advising them of their rights

told flight knowing there was a problem then told flight had been cancelled until six in the evening and then later told they would not be any ba flights from here or gatwick. they wa nt to flights from here or gatwick. they want to know when this problem is going to be fixed and when they are going to be fixed and when they are going to be travelling but i have spoken to british airways and they say they are working tirelessly to fix this problem but could not give me any indication of what timescale that might involve. they are hoping that might involve. they are hoping that during the night flights will be able to take off on long haul services to a view to land here in the morning and hoping the system will be up and running again in the morning but that at the moment seems to bea morning but that at the moment seems to be a hope rather than a firm expectation. they are advising anyone due to travel to check before setting out to the airport. the extreme measure today telling people not to come here. foreign airline,

thatis not to come here. foreign airline, that is extremely unusual because they were so many people in the terminal, people trying to get information, that the situation was getting tricky indeed. as i say, no clarity yet on how much longer this chaos will continue. police investigating the terror attack in manchester have released images of salman abedi, on the night he carried out the bombing. detectives said they were building up detectives said they were building up the detail picture salman abedi of, his associates and the wider conspiracy. in a crowd he would barely have been noticed. this is the manchester bomber on the night he murdered 22 children, women and men. a rucksack on his back, he'd flown in from libya five days before. police have released this picture, its background removed, because they want information

about what he did in that time. day and night they've crisscrossed manchester, raiding buildings, arresting people. this was moss side this morning. the area was cordoned off for a while with a bomb disposal team on stand—by. there is no letting up. there were three more arrests overnight. we now have 11 men in custody. there is now 17 searches either concluded or continuing on various addresses, largely in the north—west of the country. in another raid this morning, armed officers blew open this door in cheetham hill, a suburb in north manchester. about 3am, i heard a blast. waking neighbours and making yet more arrests. local people have helped us establish the identities of the 20 and 22—year—old men arrested here last night and we've already been able to establish a link between one of them and a member of salman abedi's family. that's the pattern of the police investigation. start with the bomber, find out who his friends

and acquaintances are, and arrest them. police are increasingly confident. tonight they revealed that, after the bombing at 10:33pm on monday night, forensic officers went straight in to examine the aftermath. within two hours, they'd identified the bomber, possibly from id found on his body. they've tracked his movements from the family home to the flat he's said to have rented before disappearing to libya, returning on the 18th of may, to move into a city centre apartment where the bomb was likely put together. they've pieced together his network. friends and relatives are in custody. they're gathering financial evidence of who backed him but, crucially, they now know how the bomb was put together. that will help them judge the ongoing threat of another attack. people continue, as requested, to report their concerns. tonight again, the police were checking suspicious items, this time near manchester's main station. the bomb disposal team again on stand—by. the uk's prime minister has

announced that the threat level has been reduced from critical to severe following significant progress in the police investigation. in central manchester well—wishers continued to lay flowers and pay tribute. the pa rents of lay flowers and pay tribute. the parents of one of the victims paid a moving tribute to her daughter, 18 01’ moving tribute to her daughter, 18 or older. visible and armed, the police out on the streets, there both to protect and reassure the crowds. the threat level has been lowered, an attack considered highly likely rather than imminent. but soldiers will continue to support the police until monday at midnight. the independentjoint terrorism analysis centre has this morning taken the decision to reduce the threat level from critical to severe. the public should be clear

about what this means — a threat level of severe means an attack is highly likely. the country should remain vigilant. it means that 1,300 events, happening across the country this weekend, will remain under heightened security. at wembley, the fa cup, between arsenal and chelsea, passed off peacefully. at the let's rock festival in shrewsbury, the police mingled with the audience. and every one of the 50,000 spectators at radio 1's big weekend in hull are being searched at least once. the effect of the arena attack has been felt by millions of people and thousands have now been to pay their respects to those who died. 18—year—old 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 discovered her daughter.

there she was on the stretcher. they were working, doing resuscitation and taking her down the stairs. i was just screaming and shouting at her. i was rubbing her hands. i was rubbing her tummy. i was rubbing herface. all the images are so vivid now. i can see everything. this evening, the teenager's parents laid their flowers alongside the others at the memorial which has become a focal point for manchester's grief. applause and then balloons flying free. there was applause, respect and love for a family needing comfort at this, the hardest of times. the g7 meeting in italy has

concluded with no indication from the us whether it will commit to the paris climate agreement. president trump spoke to troops in sicily. he did not mention disagreement over the paris climate deal. he is now on his way home without customarily press c0 nfe re nce . this summit was all about one man and whether he was ready to stand shoulder to shoulder with these fellow leaders to tackle the world's problems. well, donald trump did turn up, but he didn't always look comfortable. he refused to reaffirm his country's commitment to curb carbon emissions, to the anger of his allies. translation: the entire discussion about climate was very difficult, if not to say very dissatisfying. we have a situation where six, and if you include the eu,

seven, are against one. scientists believe that global warming is changing the world's climate and, two years ago in paris, almost 200 nations agreed the first legally—binding targets to scale that warming back. today six leaders reaffirmed their strong commitment to implement that deal swiftly, but the president refused, fearing it could cost american jobs, tweeting that he'd make a decision next week. as he left for home, the president said nothing about the paris deal but told us troops in sicily that his overseas tour had been a success. from saudi arabia, to israel, to nato, to the g7, we made extraordinary gains on this historic trip. this disagreement over climate change has shown that donald trump is ready and willing to confront his allies in europe. in stark contrast to the warm words he offered partners

people very busy right now down at the main office of ba, and at the airport well. and you will have various calls over a day, with another one and probably about ten o'clock. there will be a crisis active, with everybody tried to manage the situation. 0bviously, active, with everybody tried to manage the situation. obviously, the problem that british airways has with this is that everything is now connected, these days. so once upon a time, you would phone up booking agent, you didn't have a smart phone that connected your booking plus with everything else. 0nce that connected your booking plus with everything else. once you take one rung out the latter, the whole thing collapses. we have seen before with delta airlines and others. an epic the main challenge the bridge 0wais will now have is around the world where they have plans that are out of kilter, with the system not quite there. it will take a few days get back on it. a lot of the

passages have been frustrated about the way that it has been handled. what you think it had done better? from my express, sitting in his chair at getting grilled some years back by you and your colleagues, here, there is a degree to which bad news is never going to be taken well. and i think everybody accepts that it well. and i think everybody accepts thatitis well. and i think everybody accepts that it is difficult. —— from my experience. a lot of people have been complaining about not being told directly. when the website is down and there is no way to e—mail or to do that, then twitter, as they have been using, and the bbc, is a way to communicate. my advice to people is to be honest, give people clarity where you can. but don't give any false expectations. the only thing that i would have done probably differently today would be not to come out and say there might be flights after six o'clock. you need to be clear. you need to tell

people not to come. either that or told to come monday, sunday, or whatever. but when people sit here as they don't come to the airport, people tend to just ignore that, and go anyway. that is why i think it isn't expressly challenging situation when there is not way to just go directly to the consumers with a message. gregg allman, a founder of the allman brothers band, has died at the age of 69. a statement on his website says he had struggled with many health issues. gregg allman and his older brother duane started the band in the southern american state of georgia in the 1960s. appropriately enough —
