investigating the terror attack in manchester released cctv images of salman abedi, the man who carried out the bombing on the night of the attack. they are asking for information on his movements in the days before. they are building up a picture of salman abedi and his associates. 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. british airways says it's aiming to resume most uk flights on sunday following a massive computer failure that left thousands of people stranded around the world on saturday. passengers have been expressing their anger

with the airline after all flights from britain's two biggest airports, heathrow and gatwick, were cancelled on one of the busiest day's of the year for families going away. here's our business correspondent joe lynam. 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 to a refund and compensation. ba say that a problem with the power supply had caused the it outage, affecting everything from check—in, to boarding, to baggage throughout the airline's global network and it apologised to its customers.

a senior figure in the aviation industry said an it failure of this magnitude was extraordinary and rarely seen. he added that 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. doctor todd curtis is a airline security and safety expert. he's also a former boeing safety engineer and founder of airsafe.com. hejoins us now from boston. ba do seem to have been rather caught unawares? it appears and this is partly due to the nature of the problem. the catastrophic failure, albeit temporary, of a complex system. it does seem rather strange

that the airline should be so caught unawares? it is probably to do with the nature of what happened. it a p pa re ntly the nature of what happened. it apparently affected the entire system and once you had a situation where aircraft could not be part or arrive, they were overwhelmed. many of the failures and it seems you have seen, of crowds, of baggage left u na ccou nted, have seen, of crowds, of baggage left unaccounted, is due to the system being overwhelmed by the failure. ba has been overwhelmed and it has affected gatwick and heathrow, what effect will it have on other parts of the world? heathrow, what effect will it have on other parts of the world7m appears this particular problem was limited to ba and perhaps there is something they will find out during the investigation that it is something common to other airways. the crunch point, if ba do not take

off and land will it affect other airports? it will but not in a major way. there will be flights coming from other parts of the world and unlike heathrow and gatwick, british airways flights are far smaller. what do you make of the way the airline has handled this? they are doing the best they can, given that the nature of the failure is with their it system, they had a difficult time getting information out to their passengers and even to their employees. it is not really something that you can practice ahead of time. failures at airports can be practice but not when the entire it system is damaged. we did hear people complaining, older

people not being given chest to sit on, people not being given food vouchers... what would you expect them to do? we have a lot of rules in place to compensate passengers. certainly, when you have a situation when a high percentage of people suddenly have this problem, even the airlines is the best contingencies would have a problem. iam not surprised that they have been some scattered complained about the tardiness of service. thank you very much. let's take a look at some of the other stories making the news: venezuela has banned the importation of gas masks, helmets and bulletproof vests, to try and stop anti government protesters getting hold of them.

the demonstrations, which have been taking place almost daily, are often met with tear gas and water cannon half a million people have been displaced and more than 120 killed, in severe floods in sri lanka . it's the worst flooding on the island for more than a decade. landslides have blocked roads and made trees fall. military boats and helicopters are struggling to rescue those trapped by floodwater. the convicted drug trafficker schapelle corby has been deported from indonesia after serving nine years in prison and three on parole. the former beauty therapist from australia was jailed for drug offences. she was released from prison in 2014, but has only now been allowed to leave after fulfilling the conditions of her parole. leaders of some of the world's most powerful nations have left the g7 summit, without agreeing a joint statement on climate change. six of them did reaffirm their commitment to the paris accord on reducing greenhouse emissions; but president trump refused to sign up for the united states, saying he'll make his own decision next week. from sicily, james landale reports.

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 in the middle east. james landale, bbc news, sicily. stay with us on bbc news, still to come: one of the founding fathers of southern rock, the musician gregg allman, has died. we look back on his life. in the biggest international sporting spectacle ever seen, up to 30 million people have taken part in sponsored athletic events

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

as part of the allman brothers band, one of the biggest acts of the 1970s. which made what happened next all the more unusual. his marriage to cher, a romantic and professional relationship that caused a little controversy. she had the big idea to go on—stage together. and we got to europe, and half the audience over here, they was in tuxedos and the other half were in backpacks. and people were booing and the others were saying "get them off the stage!" cher lead the morning on social media, tweeting... melissa etheridge posted... and rock singer john mayer tweeted... gregg allman was born in nashville, tennessee, in 19117. together with his brother duane, he formed the allman brothers band in 1969.

at the centre of much speculation. david 0rnstein was at wembley. security was understandably tight as wembley welcomed 90,000 fans for the show piece of english football. after an impecably observed minute's silence, arsenal made a blistering start, opening the scoring through alexis sanchez. commentator: sanchez is in to score, the flag is up though. the goal given after suspicions of handball and offside in the build up. it could have been worse for chelsea. gary cahill making two goal—line clearances and they were also rescued by the post. the premier league champions suffered a further set back after halftime.

victor moses shown a second yellow card for diving. but that briefly rallied the ten men. diego costa with the equaliser. no sooner had chelsea finished celebrating than arsenal were back in front. aaron ramsey timing his arrival to perfection. his club now the most successful in the competition's history. at the end of a vintage fa cup final, chelsea's dreams of the double are ended by arsenal. an otherwise disappointing season for the gunners finishing in glory. this team has suffered and united and responded. i said that last week which team would win the championship with one or two good buys, and keep them together. i think we're on a good way. despite this success, questions remain offer the future of wenger, whether he stays or goes — he's certainly made his mark. there were several other cup finals in europe on saturday. celtic have won the cup in scotland, giving them a clean sweep of trophies and an undefeated domestic campaign.

it took a late goal though to clinch the cup — this injury time winner from the substitute tom rogic against aberdeen. it completes an all conquering season for celtic — both domestic cups and the league title won in their first under the management of brendan rodgers. it has been a dream. you could never have sat down, and any manager, coming at the start the season, and writing down what they would have done. but they said to be players before they went out that this is a game where you want them to write about it afterwards, but you have to make it. you have to make history, doesn't just make it. you have to make history, doesn'tjust happen. make it. you have to make history, doesn't just happen. the make it. you have to make history, doesn'tjust happen. the players went out and did that, and in the second half in particular, were brilliant. barcelona ended their season with a trophy — the third successive year they've won the copa del rey after victory over alaves. in france the cup was won by paris st germain as they completed a cup double for the season. while in germany,

borussia dortmund finally won the trophy. they've been beaten in the last three finals but a penalty after 65 minutes gave them a 2—1victory over eintracht—frankfurt. the developer of the google—owned computer algorithm that has defeated masters in the ancient chinese board game, go, says the computer will no longer be used to play humans. the algorithm easily defeated the world's number one player in china this week. the company which developed the algorithm said the computer had already surpassed the top human players of the complex game, and will now be applied to new scientific and medical challenges. a reminder of our top story. police in the uk have released cctv images of salman abedi, at the manchester bomb, who can be seen wearing dark clothes, a jacket, trainers, and a cap. that is all we have time for the moment. thank you for watching

bbc news. hello once again. we really crammed in a great deal of weather across the british isles during saturday. bright enough for many, and the temperatures really responding to that, as well, 27, again, around the murray firth, down across east anglia, and on the eastern shores of england. but all that heat eventually sparked thunderstorm activity. a lot of you telling us about that on our twitter feed. and it was really there to be had right across the north of england. spectacular amounts of lightning for some of you. but underneath it, my word, what a drenching to be had. notjust of rain — a lot of you reported on the hail, and for some, my word, it alljust passed you by, and it was a glorious day. first off on sunday, a fresh start for many. single figures in some southern counties. a dull old start or the north—west of england, then arching through north—west scotland, and a chance for a little bit

of rain on the breeze. once again on into the day, a lot of fine weather, maybe one or two showers on the eastern borders of england and scotland. further west, dry, fine for the most part. bits and pieces of sunshine coming through boosting temperatures. northern ireland would do nicely. dry weather there. so to across the north of wales, northern england, that south and west, there is the next belt of whether gradually working its way in from the south—west. not the fastest thing on two legs — it will take time before you see any evidence of that getting up towards london. it will be late in the day before some of that rain begins to break out towards the meridian towards east anglia. behind, much dry air and coming back into the south of the british isles. that could spawn some quite strong thunderstorms. temperatures will not be lower than 1a or 16, a fresher feel before the rain belt.

bank holiday monday, the rain further north the area most at risk of seeing temperatures soar away again with the attendant thunderstorms is east anglia and the south—east. that's a little fresher, quieter, across the south—west. monday into tuesday, an area of low pressure just throws this weakening weather front across the british isles. notice the number of isobars. quite winder as we get to wednesday, when it will settle down. and on into thursday as well, with the high pressure building in. with the passage of the weather front, and some rain in the midweek — it will be a good deal quieter. this is bbc news, the headlines: british police have released new cctv images of the manchester suicide bomber, salman abedi, on the night he carried out his suicide attack. 11 people connected to him have now been arrested. meanwhile the authorities have lowered the threat level
