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. in a moment, we'll be speaking to our correspondents in manchester

to get the very latest — catriona renton, who is at st ann's square in the city centre, and clare fallon, who is at greater manchester police headquarters. but first, with me is reg walker, a security consultant who works at iridium security. it manages, coordinates and advises on security at large scale events. reg will be working at the fa cup final this weekend. good morning. thank you for coming in. what sort of challenge does the fa cup final pose? i think the sheer scale of the event, the interest, the numbers of people, the multiple entry points, i think everyone is confident that the amazing security processes that have been put in place in view of the manchester are atrocities are more than capable of protecting the public over the weekend. replicated at many other events. i think the response from

police and intelligence services immediately after manchester was absolutely amazing. there was immediate contact with the events coming up this week. there were recommendations at enhanced levels. deployment of national security adviser is to events as well. i am quietly confident this week is incredibly safe for anyone wants to enjoy themselves. what will ordinary members of the public see that is different? i think probably more armed police, potentially some members of the military. i think what is more important is what they might not see. the covert acids, the plainclothes assets. also, the use of technology. looking for anything that may pose a problem to be public. it is most like an onion with the event and the public at the heart of it, protected by layer upon layer of security. it is a difficult balance. if there is too much visible of extra security, that can

worry? visible of extra security, that can i visible of extra security, that can worry? i think it can. what we are seeing on social media is people saying that they are reassured by the extra security measures. they are very understanding of additional search procedures as well, which may be time consuming for fans attending events. again, in the main, people saying this is great, it makes us feel secure. allow some extra time to get in. certainly. don't take large bags. anything that is not necessary , leave large bags. anything that is not necessary, leave it at home. most important thing is enjoy yourself. what about the threat level being at critical, the highest level it can be? does that automatically trigger things that otherwise would not be happening? i think it would. you would automatically enhance your security procedures and the numbers of staff at events. it means an attack is imminent. however, at this moment in time there is no intelligence to suggest there is a specific threat at any event. but it

isa specific threat at any event. but it is a significant precaution borne out by intelligence from police and intelligence services, who are best placed to make these judgments. thank you very much. i hope you have a smooth fa cup final. catriona renton is at st ann's square in manchester city centre. behind you, immediately we are struck by the enormous array of tribute is still there? yes, and indeed is it is growing. people still coming here. it is so quiet. it is obviously a busy saturday morning, a bank holiday weekend. people stopping here to pay tribute, to quietly reflect. the emotions very much of sadness and anger and defiance, as this city tries to get back to normal. the chief constable of greater manchester police, ian hopkins, came here yesterday evening to reassure the people of manchester that police are doing all they can to make them safe. that is important

this weekend because there are a number of big events happening in manchester. the great city games, which started yesterday evening. the great manchester run, which is tomorrow. 30,000 runners registered for that. and the charlatans —— the cha rlata ns for that. and the charlatans —— the charlatans playing at the emirates old trafford tonight. a lot of big events. police geared up for it. we have seen a big police presence in manchester this morning. i'm joined bya manchester this morning. i'm joined by a couple of guests who have been passing by to pay tribute. susie and her daughter, camille. you have come here, a terrible feeling of sadness but defiance from the people of manchester? completely. it is hard not to meet somebody who has been affected because they know a victim or have a child affected. we live next door to somebody who lives as mac quirk said stepping hill. i dread to think some of the things he had to witness on monday evening.

yes, you worry about coming into the ce ntre yes, you worry about coming into the centre but you don't want to be trodden down by this utterly depraved act. we thought we wanted to pay our respects. these big events happening over the weekend. the police doing everything they can. they are 100% confident they are doing all they can to keep people safe. how do you feel walking around the city centre? people safe. how do you feel walking around the city centre ?|j people safe. how do you feel walking around the city centre? i feel comfort seeing the police, to be honest. there is an increased police presence. it wasn't going to deter us. presence. it wasn't going to deter us. thank you. break, you are manchester born and bred. tell us how you feel the city is coping? very sad. schalke up. everybody is just grieving because of what happened on monday night. —— people are sure goal. is the police presence reassuring? yes, you feel

safer on the streets of manchester. how do you feel about the events going ahead, is that the right thing? yes, because the people of manchester can get back to normal. we're not afraid. you have been looking at the tributes. 0bviously you are very moved by what you have seen? i am shocked. my is broken. because of manchester, where i was born. the crowds here growing. people still continue to bring flowers. there are a load of events going ahead this weekend. police are working hard. i understand that some collea g u es working hard. i understand that some colleagues have been spoken to by the police and the police have asked us the police and the police have asked us to specifically thank members of the public for the help that they have given them over the last few days. and also, ariana grande, the concept that happen on monday night, when so tragically that incident

happened, ariana grande has been tweeting. she is going to come back to the incredibly brave city of manchester. she is going to hold a benefit gig here for the victims. she says that music is something that should he loss, bring us together. and make us happy. she says she will continue to do that because the victims are in her heart and mind every day, as they are obviously very much and so in the hearts and minds of the people who have come here do these great this morning. you can see clare fallon at greater manchester police headquarters. bring us up—to—date with the state of the police investigation? those latest arrests were made during the early hours of this morning. we have been told that two men, aged 20 and 22, were taken into custody when police carried out a raid in the cheetham hill area of manchester.

that area is actually very close to manchester arena itself, where the bomb attack happened on monday night, with 22 people being killed. police have told us that when they went into a property this morning in the cheetham hill area, they used a controlled explosion to gain access to that address. in all now, they have 11 people who are in custody. associated with this investigation. they have made 13 arrests since monday, but two of those people have been released without charge. we do know that one of the people arrested is salman abedi's brother, ismail abedi. just consider the number of arrests made since monday night. consider also the number of raids that have been carried out on a number of properties that are the subject of intense forensic searches. that gives you an idea of the scale of the police investigation that we are dealing with. police have told us they are making immense progress with the

investigation. they have described some of the arrests they have made as being significant. they have also said that during the searches of the various addresses they have discovered some items that are of real importance. they have said they believe they are dealing with a network of people, rather than just the bomber himself. but clearly, they have used the phrase fast—moving. that is the phrase they have used time and time again in recent days when describing this investigation. i would expect there will be more developments over the course of this weekend. clare fallon. let's assess this now. joining me now from salford is the former chief prosecutor for the north west, nazir afzal. and head of the police and crime commissioners association. good morning. good morning. immense progress. let me pick up that phrase. is that you're reading of what the police are achieving?

absolutely. this is an extraordinarily complicated enquiry. 11 suspects in custody, 12 address is being searched, a substantial amount of forensic evidence, dna evidence, the digital evidence, international evidence, all of which has to be collated. it is a fast—moving investigation. they recognise the need to reassure, they need to deal with this expeditiously. when the arrests are made, they have a specific timetable, don't they? absolutely. with terrorism offences, it is different to any the kind of criminality. 36 hours is how long the police to detain and make a judgment whether somebody should be charged or might not. in terrorism cases they have substantially longer given the nature of the investigations. they have up to 1a days with the authorities. and a further 1a days if they go to a high

courtjudge. they could detain for up courtjudge. they could detain for up to 28 days. one has to recognise that as fast—moving as it is, there isa that as fast—moving as it is, there is a substantial amount of material to go through and interrogations, and we also recognise there are probably enquiries abroad. all of which have to be assessed, ijudged and at some point prosecutors have to make a judgment as to whether or not people should be charged. there isa not people should be charged. there is a wider picture here as to why somebody like this would ever consider doing something as horrific as he has done. and trying to get to the bottom of that is a rather more conjugated question? it is. these are the questions we are asking now, but the answers will come in the weeks and months to come. we don't know. we are told that he was at some point referred to the authorities by members of the muslim community, who were concerned about his behaviour. we don't know how detailed this was. we know there are financial issues, bank accounts opened. we know this was a

relatively sophisticated plot which is devastated manchester. we have to understand why people are radicalised and we have to work together. one of the things that people have begun to understand is that the preventive strategy, which has often been targeted as being somehow a spying mission of some kind, is not bad. this is a safeguard admission. this is about ensuring that we try to identify what people are going through and what people are going through and what issues need to be resolved, and ultimately provide them with support. something like a thousand people in the past few years have been given substantial support which has prevented them from being radicalised. far right activists also come within this strategy. more than a quarter of the referrals are from far right backgrounds. this is about ensuring that we protect people who may be radicalised, ultimately about protecting us all. if there are referrals going on to the level you describe, somebody has to look at whether there is scope

for more referrals to be made when they are made, that the response is more effective. that has to be considered, hasn't it? absolutely. we have to ensure there are more mentors. the government indicated they would be increasing the funding for the strategy. this is about safeguarding. this is about ensuring the communities can feel confident, they can report and those reports can be acted upon. it doesn't mean that every single person referred, in fact more than two thirds, nothing happens to them, they are simply given guidance and support. this is about all safe and we have to recognise that is something we have to do more of in the future. thank you. let's talk about the political development. the prime minister is chairing another meeting of cobra this morning. ali price is outside the cabinet office in whitehall. what is likely to be discussed this

morning? well, the meeting took place at half past nine this morning. as we understand it, it is still going on. they will be getting a general briefing about the police investigation. plenty of police raids and arrests. and of course the more broader security picture both domestically and internationally. the prime ministerflew home domestically and internationally. the prime minister flew home early from a meeting of g7 leaders, which she was attending in sicily in recent days. at that meeting she would have been discussing among other issues... have the g7 meeting they talked about online terrorism. this is a full cobra meeting. it will be attended by senior members of the government, the foreign secretary, the defence secretary, and they will be hearing about the intelligence services' investigation

until now as well as the latest with the police investigation. it was from a cobra meeting that the threat level in the uk was taken up to critical. that means that a terror attack is expected as imminent. that has been at the critical level since the attacks on monday. it has not gone down so far. they will be discussing, no doubt, whether that level of terror threat should remain the same. thank you very much. apologies for the slight glitch on the line. the headlines on bbc news: armed police will be on duty at high profile events around the uk over the bank holiday following the manchester arena concert attack. new revelations about president trump's son—in—law, jared kushner, and his alleged involvement in secret dealings with russia. leaders of the g7 leading industrial nations failed to reach an agreement on climate change at a summit in italy. now let's get a round—up

from the bbc sports centre. we'll start with 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 i don't care about me. i care about us winning the game on saturday. when you go in a game you can accept ina cup 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 my —— make me personally ina game i have is my —— make 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

34 through a season unbeaten. winning 3a out of 38 games and winning both domestic cups. that is our plan, thatis domestic cups. that is our plan, that is ouraim 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 teams 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 v exeter. ijust want i just want us to ijust want us to go and enjoy it. it would be lovely to get our hands on the trophy. it would be nice to think we can relax but that will not be the case. for us, this final would have been beyond our dreams a

couple of seasons ago. but we are there. if we play like we can, there is no reason why be can't get our hands on silverware. it didn't feel like we had achieved everything we wanted to bite reaching the final. those feelings have to be backed by actions. the key to me is to show the form we can. it's also the pro12 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 around quarter past six this evening. england's cricketers take on south africa in the second one—day international this morning in hampshire. england can win the three—day series today, and bowler liam plunkett says a victory will set them up well for the upcoming champions trophy. there is no truer test or tougher test tha n there is no truer test or tougher test than playing south africa, the players they have got. a lot of them are informed. they have been playing in the ipl, scoring runs. to win a

series against south africa and perform well, it puts you in a great place for the icc. three tough games. there is no better perform. that is it for now. you can keep up—to—date with those stories on the bbc website, including qualifying for the monaco grand prix, which is underway. more in the next hour. thank you. president trump's son—in—law and senior advisor, jared 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 david willis reports. according to these latest reports, jared kushner, who as well as being president trump's son—in—law, is 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 that he had misled other administration officials about the extent of his contacts with the ambassador. in the end, the communications channel was not set up. it was reported yesterday, that mr kushner had a separate meeting with the head of a russian bank that has been subject to sanctions imposed by the 0bama administration. reuters news agency is saying he had several telephone conversations with sergey kislyak. mr kushner is being investigated by the fbi as part of their enquiry. this does not necessarily mean he is suspected of a crime. 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. james landale has more. music. at this summit in an ancient town on the coast of sicily, there has been some harmony between the g7 leaders about the need to do more to tackle global terrorism. but there have been dramatic and discordant notes on trade and climate change. donald trump has voiced his anger at the impact he believes free trade is having on the us car markets. and 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. g7 leaders are using this summit to try to stay the president's hand. they are 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 is out, it is one more reason for all the other countries to come together to say, of course, and to make sure that the paris agreement moves ford. mr trump's advisers say his views on the paris deal are evolving, but so far no agreement has been reached. the italian prime minister said the issue was still hanging. this summit has literally been overshadowed by the ancient volcano of mount etna. but for many of the world leaders, this is their first time on the world stage, and inevitably the focus was on the one in particular.

donald trump. and the overriding aim of the summit is to keep the president donside, convincing him that it president donside, convincing him thatitis president donside, convincing him that it is worth his while to be a member of this small club of large nations, so they may push on climate change, but not that hard. james reynolds is in sicily for us. what is your assessment of what has been agreed and what still lies ahead in the column marked difficult? pretty much almost everything in the difficult column. this is the g7 but in some way it is six countries against one. the six leaders of the other countries are trying to persuade donald trump to join them on climate change. it is interesting that the un secretary—general, who i spoke to earlier, suggested the climate change agreement would survive or whatever donald trump decides to do, whether he decides to keep the united states in it or withdraw. this is about the six nations trying

to persuade donald trump to move to their side. they will have noticed in recent months that the us president is a man who sometimes changes his mind. he changes his position. heart of the aim is to see where he stays rigid and where he moves. that is an important part of the summit for them. and his views, according to his office was, araf least evolving aren't they? yes. that is something that the un secretary—general will try to cling onto and some of the other leaders will try to cling onto as well. they will try to cling onto as well. they will want to push that evolving towards the position of the six countries who think that the paris climate agreement is worth preserving. james, thank you. proposals to try to reduce the number of children diagnosed with autism are being considered by the nhs in south—west london. the local clinical commissioning groups say nothing has been decided yet, but the national autistic society has written to them to say it's

"deeply concerned" about the plans. jane dreaper reports. children with autism struggle to interact with the world around them. they are often diagnosed between the ages of six and nine. services in south—west london are very stretched, and the nhs there is considering a controversial idea. a team that is supposed to carry out 750 annual assessments is actually getting 1300 referrals a year. so nhs commissioners in five local council areas want to reduce the number of children diagnosed with autism, by focusing specifically on the most severe cases, where children have another illness such as depression. a leading autism charity is deeply concerned. we think it is short—sighted and can cause lots more problems and be more costly in the long run, and will have a massive impact on those
