line confirmation of some sort of problem. we do not know the extent of the problem. what happens in these circumstances is that you find out social media are ahead of confirmation from official sources and certainly people at heathrow airport, terminalfive, predominantly used by british airways, are reporting problems. we hear that there are long queues. we also hear from hear that there are long queues. we also hearfrom individual travellers about being stuck on aeroplanes are unable to take off. notjust at heathrow but other airports around the world. this is yet to be confirmed. i spoke to a source at heathrow airport who said he understood the problem is wider than just heathrow airport. it suggests it isa just heathrow airport. it suggests it is a global power —— global problem for british airways. at one stage there website was down but it seems to be back up. i spoke to air

traffic services and they said they could not confirm anything. there are rumours on social media that the airline may have been hacked or they had some sort of downtime to update their systems and they have not gone back up again. those rumours are spreading on social media and we do not have those confirmed at the moment. it seems to be a fairly substantial problem, the precise extent of which we are not sure of at the moment. in the last few minutes, police investigating the manchester bombing say they have evacuated people from part of the moss side area of the city, as part of an ongoing search. police arrested two more men overnight during raids elsewhere in the city. 11 people are now in custody. across the country security arrangements for events planned for the bank holiday weekend have been reassessed. extra officers are expected to be on duty at football cup finals in england and scotland and the great manchester run. sarah smith reports. armed police on the streets of hull.

the security at the festival taking place here this weekend has been reassessed, as it has at hundreds of other events. the operation in manchester may be making good progress, according to counter—terrorism detectives, but the threat level remains at its highest. as well as radio 1's big weekend in hull, extra security will be in force at the fa cup final at wembley, the scottish cup final at hampden park, and sporting events in liverpool and manchester. in the city centre, the floral tributes keep coming. police have praised the spirit of the people. and they want to assure everyone that progress is being made. so much has been achieved in that period of time. it is at huge pace. we have made huge grounds in terms of the investigation, but there is still a lot of work to do. officers and other agencies are working with us around the clock to make sure we do that. the arrests keep coming.

three more in the city overnight. locations being searched around manchester include a flat in this block rented by salman abedi several months ago, which may have been a bomb factory. another flat here in central manchester is where he is understood to have put the bomb together in the hours before the attack. his 22 victims have all now been named. most recently, 15—year—old megan hurley from halewood in merseyside. the principal at her school described her death as a huge loss to them all. last night, pink balloons were released in memory of all who lost their lives. and while the threat level remains critical, the message was to go out, enjoy the weekend but remain vigilant. sarah smith, bbc news. our correspondent catriona renton is at st anne's square in manchester city centre.

as you will hear, it is so quiet here today but despite that crowds are huge. the black coming here, still paying tribute and bringing flowers. you can see the carpet of flowers. you can see the carpet of flowers that keeps growing as people come here to remember the 22 victims of monday night's atrocity. i am joined by two people who are volunteering to help at the moment. a police support volunteer and a volunteer with the british red cross. there has been nature mendis response from the people of manchester to support each other. what have you been doing? there is quite a lot happening with the emergency services, greater manchester police put extra officers on the street and the voluntary special constabulary have been out

in force. on tuesday the were 165 volunteers, part of the special constabulary, out on the streets of manchester protecting people. police say they are doing everything they can this weekend to make people feel safe with big events happening. are the police able to do enough and to people feel reassured? yes, along with all the other emergency services. the response from everybody thanking the forces involved is tremendous. as we are filming, there are two armed officers walking behind. the respect is fantastic. tell us about the response you're getting. people have been fantastic, so generous, someone gave me a hug this morning, gave me an umbrella, it is fantastic. the

tributes are crowing and there are big events happening in manchester, the great city games, the great manchester run tomorrow, 30,000 runners registered, and it is expected there will be a big turnout of crowds and police. they are doing everything they can to reassure people. the message they had been giving people is to go out and enjoy yourself as planned but keep being vigilant. our news correspondent clare fallon is at greater manchester police headquarters. an update on the police investigation, activity in moss side? yes, in the last few minutes greater manchester police have put out a statement to say that as part of an ongoing search and evacuation has happened in moss side. they described relocating people as a

precautionary measure to ensure safety. the most recent arrests came in the early hours of this morning not in moss side but in the cheetham hillarea, not in moss side but in the cheetham hill area, close to manchester arena. they arrested two men aged 20 and 22, as they carried out a raid ona and 22, as they carried out a raid on a property. in order to gain access to the property they carried out a controlled explosion. the latest information from greater manchester police is that they have 11 people in custody linked to this investigation. they arrested a total of 13 people since monday night. two of 13 people since monday night. two of those have been released without charge. one of the people who was arrested was salman abedi's brother —ish male —— is male ——... i think

you can get the idea of the scale of this investigation. they said some of the people they arrested are significant and that they have made significant and that they have made significant finds during some of their careful forensic searches but clearly with these developments in the moss side area this morning, and evacuation of part of that area, it is clear this situation is still developing. in the wake of the terror attack in manchester earlier this week, extra police officers have been called in to help with security at radio one's big weekend music festival. other security measures have also been put in place at the festival taking place in hull. 50,000 music fans are expected. our correspondent noel phillips is live at radio 1's big weekend in hull for us now. as you can see, final preparations

are being added to the main stage as festivalgoers make their way in for big weekend, radio 1's flagship musical festival known for attracting seriously well—known pop stars. it is worth finding out that amongst the festivalgoers coming to have a good time there has also been an increase in security today. humberside police, responsible for policing the event, requested extra assistance and forces from outside humberside have been brought in to help police the event. i saw armed police at the entrance today and there will be extra searches today. there will be two rounds of searches, airport style searches, a searches, airport style searches, a search on trains and buses when people leave their vehicles to make their way to the site to come in and enjoy the festival. it is worth pointing out that even though there are armed police patrolling, radio1

bosses have assured us there are now concerned —— there are no concerns. ben cooper is in charge of radio 1 and he told us about security measures in place today. we have taken expert advice from everyone that has been involved in the event and i think what we have done is make sure that safety and security has been uppermost in our minds. obviously our thoughts have been with those that were affected at the beginning of the week in manchester and that really has informed our thinking, that has really made sure that we have focused on going how do we make sure this doesn't happen this weekend? ben cooperfrom bbc radio 1. it is important that i point out that none of the main artists have pulled out from performing, everyone who was booked will be performing. also

local people in hull and is george rae here to enjoy bbc radio 1. how are you feeling? excited. where have you come from? grimsby. it is my first one, i've never been to one before and i love radio 1. it is quite significant for hull. definitely. i can't believe it has come to somewhere like hull. you are smiling so you are clearly excited. lam smiling so you are clearly excited. i am excited. i am going to love it because it is such a rare thing to come to. not everybody gets a chance. we are some of the lucky ones. how important is it, the relationship fans yourselves have with musicians. it can be seen as quite intimate at times. intimacy is goodin quite intimate at times. intimacy is good ina quite intimate at times. intimacy is good in a gig but also with big things like this, the bands need it, this is what they come here for, the support and publicity. you guys are

excited. it is worth pointing out that the director of hull city of culture told us in a statement that this weekend is a chance to celebrate life and should defiance to those who tried to divide us. president trump's son—in—law and senior advisorjared kushner discussed opening a secret communications channel with the kremlin, according to media reports. the fbi is investigating mr kushner as part of a wider probe of alleged russian interference in the us election campaign, as our correspondent david willis reports. according to these latest reports, jared kushner, who as well as being president trump's son—in—law is also one of his closest advisers, discussed establishing a secret communications channel between the trump transition team and moscow in order to discuss syria and other policy issues. he is alleged to have met last

december at trump tower in new york with the russian ambassador to the us, sergey kislyak, and mr trump's former national security adviser michael flynn to discuss the matter. general flynn was forced to resign in february after it emerged he had misled other administration officials about the extent of his contacts with ambassador kislyak. in the end, the communication channel wasn't set up. it was reported yesterday that mr kushner had a separate meeting with the head of a russian bank which has been subject to sanctions imposed by the obama administration. reuters news agency is saying he also had several telephone conversations with sergey kislyak. mr kushner is apparently being investigated by the fbi as part of their inquiry but this does not necessarily mean he is suspected of a crime. an elderly couple found 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 afternoon. a ao—year—old man has been arrested and is still being questioned. the headlines on bbc news... and evacuation is underway in moss side is part of an ongoing search in the inquiry into the manchester arena bombing. armed police will be on duty at high profile events around the uk over the bank holiday following the manchester arena concert attack. british airways apologises to passengers facing delays at heathrow following computer problems. leaders of the world's leading industrial nations, the g7, have failed to reach agreement on climate change at a summit in italy. members had hoped donald trump would join the rest of the world in combating climate change but differences remain between the us president

and other countries. our diplomatic correspondent james landale has more. classical music. at this summit in an ancient town on the coast of sicily, there has been some harmony between the g7 leaders, above all on the need to do more to tackle global terrorism. but there have also been some dramatic discordant notes on trade and climate change. donald trump has voiced his anger at the impact he believes free trade is having on us car markets. he has also expressed doubts about global warming and threatened to pull the us out of a deal agreed in paris in 2015 to limit carbon emissions. so g7 leaders are using this summit to try to stay the president's hand. and they're not alone.

in an interview with the bbc, the secretary general of the united nations said the us had to stay engaged in the paris climate accord. if one country has doubts, it is one more reason for all the other countries to come together to stay the course and make sure that the paris agreement moves forward. mr trump's advisers say his views on the paris deals are evolving but so far no agreement has been reached. the italian prime minister paolo gentiloni said the issue was still hanging. this summit has been literally overshadowed by the ancient volcano of mount etna but for many of the world leaders here this is their first time on the world stage and inevitably the focus was on one in particular, donald trump. and the overriding aim of the summit is to keep the president onside, convincing him that it is worth his while to be a member of this small club of large nations, so they may push him on climate change but not that hard.

let's try to bring you a little more about what ba are describing as an it outage which is affecting heathrow and some other airports. it might have international implications. we can speak to a passenger at heathrow. thank you for coming on. what is happening where you are? i am at terminal five at heathrow and i was due to fly at 7:40am to tokyo. when i got to the airport to the queues were outside the door. full is the —— eventually

some ba staff asked us what flight we we re some ba staff asked us what flight we were on and if we were on our way we were on and if we were on our way we would go with them. they seems to be prioritising a few were a card member or not. people were exasperated. after a0 minutes some stuff gave people water because it is an extremely hot day. our flights actually leaving and arriving as you speak? our flight is delayed and it looks like there are a lot of people waiting in the gates. staff are not sure what time the flight will leave. apparently all be a system is in all airports, that is what the staff member told me, so they seem to bea staff member told me, so they seem to be a little concerned about how to be a little concerned about how to check everyone in and get eve ryo ne to check everyone in and get everyone through the gate. given

that it everyone through the gate. given thatitis everyone through the gate. given that it is the start of a bank holiday weekend, heathrow would have been very busy even before this happened. i think it is going to be quite a tough weekend! we will let you stay there and find out more for your own information quite apart from our own. thank you for coming on. iam from our own. thank you for coming on. i am looking at a line coming from a captain who has treated, sat ona from a captain who has treated, sat on a plane at heathrow for an hour and a half. describing the it problem as" catastrophic". sport now, and a full round up from the bbc sport centre. we'll start with cricket and the second one—day international in hampshire where england can win the three day series against south africa.

the tourists won the toss and put england into bat. jason roy is out for 8. ben stokes is in the team after having been passed fit. joe root replaces jason roy. it's not going to be an easy or happy return to formula one forjenson button at this weekend's monaco grand prix. the briton is standing in for fernando alonso at mclaren after the spaniard opted to race at the indy 500. button will start from last place after he was given a 15 place grid penalty for changing an engine. sebastian vettel came out on top in final practice, three tenths of a second quicker than his ferrari team mate kimi raikkonen. lewis hamilton could only manage fifth. the fa cup final at wembley, where premier league champions chelsea could clinch the double in antonio conte's first season in charge. they face an arsenal side aiming to finish a poor season on a high.

the gunners, who finished fifth, have won the fa cup six times under arsene wenger, most recently in 2015. a win today would make the frenchman the most successful manager in the tournament's history, but there remains a lot of speculation about whether it could be his final game in charge. wenger, though, says today isn't about him. i don't care about me. i care about us winning the game on saturday. when you go in a game you can accept in a cup final the challenge. you just want to win it. the last worry i have is me personally in a game like that. we have to forget at this moment that we won the league and be concentrated on this target. it is a fantastic target. we don't know if in the future we will have another possibility to win this trophy.

there's a huge game at hampden too, where aberdeen take on celtic in the scottish cup final. celtic are unbeaten in every domestic match this season and are going for the treble having already won the scottish premiership, as well as beating aberdeen in the league cup final. they have certainly exceeded what i thought they could achieve. myjob was to lead, to push, to demand. and the players have been able to cope with that. you would do well to see a season again like like it, to go through a season unbeaten. winning 3a out of 38 games and winning both domestic cups. that is our plan, that is our aim and we will do our best to do it. more celtic teams should won the treble in recent years but for some reason they haven't. this celtic team is very sharp, focused, very confident. they don't give much encouragement to their opponents.

we have to try and find a way to put a seed of doubt in their mind. a sell—out crowd of 82,000 people will pack into twickenham this afternoon for the showpiece event of rugby union's premiership season, the play—off final. it's a battle between the sides who finished first and second after the regular season — wasps and exeter. it didn't feel like we had achieved everything we wanted to by reaching the final. those feelings have to be backed by actions. the key for me as we go out there and perform at the level we can as a club. it's also the pro 12 final in dublin later today. welsh side scarlets, who finished third, will take on top—of—the—table munster at the aviva stadium. kick—off is at quarter past six this evening. that's all sport for now. now the weather. still some very warm sunshine this weekend but the heat and humidity

has already given rise to a number of thunderstorms. this was first thing this morning in southampton. those storms have moved away and it looks like it will be fine and warm and sunny for the cricket, the second odi. this is the line of rain and storms that has been working north. ahead of it, warm sunshine for a while in cambridgeshire here and i don't think we'll get many showers here at all. this could be one of the warmest parts of england today. the showers petering out as they move north. a second batch of storms developing in north wales, heading into northern england. at the same time, turning cloudy and wetter in northern ireland. for scotland we could see some showers heading north into hampden park for the scottish cup final this afternoon. across the moray firth, that sort of area, temperatures will not be far away from 30 degrees, as they were yesterday. western fringes of scotland catching some storms. later on these storms developing across the north of england, primarily the northwest, could be some hail and gusty winds.

going to feel quite cool under the rain in northern ireland. the cool breeze will keep more cloud in wales and the south—west but further east after those morning showers and storms we have some very warm sunshine, temperatures close to 28 in cambridgeshire. for wembley, warm as we head into the evening and the fa cup final, typical fa cup final weather. sunshine to end the day here but storms moving northwards across northern england and into central and southern scotland. those will peter out overnight. the rain will tend to ease as well but we hang onto a great deal of cloud. it will be warm and muggy for many parts of the uk. temperatures of 13—1a. we start cloudy early on sunday and it may stay that way for northern ireland and scotland although there will not be much rain here. brightening up across england and wales, some sunshine developing, warm sunshine, and then we get some late storms from the south—west. sunshine ahead of it means it will feel quite warm. a much cooler day for scotland under the cloud.

here we could get some rain on bank holiday monday. those showers or even longer spells of rain, the potential for some early thunderstorms, moving northwards. some sunshine and still some warmth in the south—east. hello and welcome to dateline, i'm jane hill. a warm welcome at a difficult week for many. this week — the aftermath of the manchester suicide bombing, we assess president trump's first overseas trip, and we look at the state of the general election camapaign here in the uk with less than two weeks to go to polling day. joining me to discuss all this are iain martin, a times columnist, the american broadcaster, jeffrey kofman, thomas kielinger of die welt, and nisreen malik, the sudanese writer. a one welcome to all of you. in manchester... in manchester on monday night a pop

concert by an american singer popular with young girls ended in carnage when a 22—year—old man born in the city blew himself up, in the foyer of the concert arena. children as young as eight were killed, and scores of people remain in hospital. the hunt is continuing for the people who supported salman abedi — many people have been arrested in the uk and, in libya, abedi's father and one of his brothers have been arrested. let's talk about the libyan connection.
