this is bbc news. i am lebo diseko. our top stories: moments before he killed, the manchester suicide bomber caught on cctv. tens of thousands of passengers stranded around the world — but british airways says it will get services running again on sunday. hello. good to have you with us. police investigating the terror attack in manchester have released cctv images of salman abedi, the man who carried out the bombing, on the night of the attack. they're asking for information on his movements in the days before. detectives say they're building up a detailed picture of abeidi and his network. from manchester, our home affairs correspondent, tom symonds, reports. 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. tom symonds reporting there. thousands of british airways passengers around the world have been stranded or had their flights cancelled after a massive computer failure. all flights from the uk's two biggest airports, heathrow and gatwick, were grounded for the day, one of the busiest 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.

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. british police have released new cctv images of the manchester bomber on the night he carried out his suicide attack. they say they've gathered significant information about his network. british airways blames a power supply problem for the stranding of tens of thousands of passengers — but says services will be better on sunday. let's get more on our top story. the investigation into the manchester bombing. prime minister theresa may has announced that the threat level facing the uk is being reduced from critical to severe following the significant progress in the investigation. it means that an attack is no longer regarded as "imminent,"

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 today's success, questions remain offer the future of wenger, whether he stays or goes — he's certainly made his mark. 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, agaisnt aberdeen. putting the seal on an all—conquering season for celtic, their first under the management of brendan rodgers. 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 and some consolotaion after defeats dating back to 2014. one of the founding members of the rock group, the allman brothers band, gregg allman, has died. he was 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, tim allman reports. gregg allman doing what he did best — long—haird psychedelia mixed with the blues, country and jazz — what came to be known as "southern rock" — 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. they enjoyed huge success, but duane would die in a motorbike accident at the age of 24. gregg continued performing, but would suffer from health problems and addiction to drugs and alcohol. he died this week peacefully at his home in savannah, georgia. described as a kind and gentle soul, a brilliant pioneer in music. music fans attending the first major concert in manchester since monday's attack have been told that "terror will never prevail." a huge security operation was in place for the gig by local band, the courteeners,

at the city's old trafford cricket ground. it was a sell—out event, but very different from the one originally planned. 0ur entertainment correspondent, colin paterson, was there. the courteeners. this gig sold out six months ago. after monday's bomb attack, the band decided it would still go ahead. their singer, liam fray, told me why. if this hadn't have happened, it would have sent out a really bad message, i think. people should be allowed to go and enjoy themselves without being scared. we were absolutely coming because it's what we do. it's what we love. we're not going to be deterred by anybody, or anything. i'm a married man. i've got a kid and all that. at the end the day, you've got to live your life. you know what i mean? you've got to live your life. now this is not normal at a gig to have armed policemen on the door. but, even with this level of security, some die—hard fans have

chosen to stay away. the first time i saw the courteeners it was actually at the arena. liam wilks has attended every courteeners gig in manchester since 2011, until tonight. he sold his tickets. ijust know i wouldn't enjoy it. i wouldn't be focusing on the music. i'd be focusing on if i saw anything suspicious, or... i wouldn't be listening to the music, i'd be watching everything else. but abbey and pete weren't going to let their big day be spoiled. they'd already decided to turn the gig into their wedding reception, buying 68 tickets for guests. what we do in manchester is we go to gigs. that's why we've had the wedding that we've had. so, we just carry on. we're with our mates tonight, our favourite band. so, we'rejust going to do manchester proud tonight and have a big party. but tonight has also been about remembering those killed on monday. this is our manchester. 0ur manchester. and the bees still buzz! don't forget, you can get in touch with me and some of the team on twitter.

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 muggier air and coming back into the south of the british isles. that could spawn some quite strong thunderstorms in the wee hours of bank holiday monday. temperatures will not be lower than 14 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 windy until 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 a new cctv image 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 of a terrorist attack from critical to severe. british airways says it's aiming to operate a near—normal schedule
