Plus, the president and the pope. Donald trump goes to the vatican for what he calls the honour of a lifetime. These two werent always so friendly. Hi, im Christian Fraser in manchester, katty kay is in new york. It is impossible for Security Services to keep every terrorism suspect under surveillance but tonight there are several signs that the Manchester Bomber was a known cause for concern. He travelled to libya and possibly syria before the attack. Members of his own Community Tell the bbc they warned authorities about him and the french government says he had proven ties to islamic state. The home secretary, amber rudd, also says the Suicide Bomber was known to the uk Intelligence Agencies and he probably had assistance from others. For the victims and their grieving families, the news is no comfort. And this was a horrific violent event, it was more sophisticated than some of the events we have seen in the past or in other parts of europe, so people are reasonably wondering whether he did this on his own and i am making sure that the police and the Intelligence Services doing that investigation have the support they need to find out who might be, have been working with him, because our focus might be, have been working with him, because ourfocus is might be, have been working with him, because our focus is always going to be on making sure we keep people safe. The best way to do that is to ensure this operation ends. Heres the Manchester Police on the investigation. I think it is very clear that this isa i think it is very clear that this is a network we are investigating. It continues as apace. There are in destinations going on extensively and taking place across Greater Magister as we speak. Certainly the investigation is moving fast. The attackers father and younger brother were both arrested today in libya. Five more people are being detained in britain. It is now thought salman abedi may have been a mule , using a device built by someone else. Our special correspondent ed thomas has more. Suicide bomber salman abedi, an extremist who attacked the city of his birth. Now investigators surround his home, like everyone here, wanting answers. This man knew abedi. He would watch him come and go from manchester to libya. Now he cant believe what his neighbour did. Unbelievably disgusted, to be honest. For a muslim, and a libyan as well for. For us, being the law of the country is most important. That is what the prophet teaches us. He was shouting out the koran in islamic. I dont know the language. The bbc was told a black flag with islamic writing was hung outside his home. Many had no idea what it meant. I remember seeing some sort of flag outside. I didnt really look at it. Was it english writing . No. A Community Worker who did not wa nt to no. A Community Worker who did not want to go on camera told us to separate people who knew salman abedi at College Rang Police several yea rs abedi at College Rang Police several years ago. They said he was supporting terrorism and had expressed a view that being a Suicide Bomber was ok. Greater magister police will not comment on those claims. And what about the Manchester Bombers family . This is his Brother Hashim now under arrest for is supporting so called islamic state. This is his father, hes now back home libya. On his Facebook Page he praises alqaeda fighters in syria. Before he left South Manchester we were told he would ta ke manchester we were told he would take part in praise at this mosque. He isa take part in praise at this mosque. He is a guy who announces it. Police now want to know if Anyone Else What Salman Abedi and his father believed. Salman abedis father, he was in the mosque . Everyone knew him. A good man . He is a good man. This man is close to the trustees at Didsbury Mosque. Like many he had no idea of the familys extremist links will stop we know he is connected to Extremist Fighters in libya. Groups close to alanda. Extremist fighters in libya. Groups close to alqaeda. To us it did not show. Is that a problem though . That people like yourself, good people, dont know who they with . We go back again, the Mosque Trustees go have to do more about that. A lot needs to do more about that. A lot needs to be done. Tonight, Didsbury Mosque said salman abedi was a coward who has crime had no praise in their religion. A man willing to kill and hurt in the city that was once his home. No doubt the community has pulled together and you can see the number of flowers that have been laid in just the last few hours. This is now becoming the focus of the grieving here in manchester. This is the metropolitan mayor of manchester. Thank you for being with us. A lot of Police Activity today. It is very noticeable for people in the city. Are you satisfied that they are getting to grips with the investigation was to mark yes, i have a high degree of confidence in what the police and Security Services have been doing. There has been a huge amount of progress with the investigation in the last 2a hours. Iam the investigation in the last 2a hours. I am confident that those responsible will be hunted down, held to account. Im also very reassured by the Police Presence that we have in this city right now. Really, the response of the public serva nts really, the response of the Public Servants of Greater Manchester has been truly magnificent. It is obviously one of most complex investigations Manchester Police will perhaps ever undertake. One of the things that alarming people is that there was Information On Salman Abedi that was perhaps missed. A Community Worker told the bbc today that they had alerted the police several years ago to their concerns. When the appropriate time cans, people will have to look back at what was known in what was not known. I dont think this is necessarily the time. But we always have to bear in mind how hard the job of Security Services is. Information is coming in all the time. They have foiled many plots in recent times and we have to give them our support because they do an incredible job. Them our support because they do an incrediblejob. This individual was an extremist, a terrorist, does not represent the Muslim Community of Greater Manchester, and certainly does not represent anybody here in Greater Manchester. This is the true Greater Manchester. This is the true Greater Manchester. This is the true Greater Manchester that we are seeing, the spirit that is coming through in these last 48 hours. You had a big event here on friday, youve got a big event, can you reassure people that you are doing everything you can to protect them . Yes, we are working closely with government the Security Services. The important thing is to get back to normal. That is the easiest signal to say we will not be beaten by what is happening. And manchester has always done that, it does not ever back down to anybody and we wont be backing down now. We want to bring the city back together. Of course people will need to be vigilant but not unduly alarmed. There will be a Police Presence on the street but the best response is to come together, be strung together, and said that defiant Manchester Message out ran the country and the world. That Northern Spirit is certainly there. The investigation is moving fast. The investigation is moving fast. The police are saying they arrested a man carrying a suspect package. What you know about the latest arrests . What you know about the latest arrests . We are just hearing of another operation going on not far from here which seems to involve about 45 Police Officers and i2 police vans. We are going down there to check out what is going on. This afternoon the man arrested in wigan was arrested because he was carrying what seems to be a suspect package. We have not heard whether that turned out to be anything or not. Then of course there were three men arrested this morning who were arrested this morning who were arrested because they knew the suspect it bomber. That is also out of the investigation. Perhaps the most significant is invalid development this evening is that the New York Times has published photographs of what appears to be the remnants of the bomb from monday night. Some details about that bomb include the suggestion that it seems to have been contained in some thin metal container, either in a blue backpack or a black vest. And that there was a trigger of some sort in there was a trigger of some sort in the bombers hands. That is probably the bombers hands. That is probably the most significant of element as we go on air tonight. Intelligence that americans journalists are getting Information Lea ked journalists are getting Information Leaked to them from american sources. I am fascinated to know how they got these pictures of the bomb that our colleague was just telling us that our colleague was just telling us about. The Manchester Attack was britains second Terror Attack in just two months. And as people rallied in london after the westminster attack, people in manchester are now pulling together. So far we know the names of 13 of the 22 people killed. As their names emerged today, one thing was inescapable the extreme youth of so many. There is a special anguish in this. The carefree tenderness of the lives lost. Olivia campbell from bury was 15. Her family spent yesterday frantically searching for her. They learned early today that she had died. Her mother, charlotte, posted this message on facebook. Saffie roussos was eight. She went to tarlton Community Primary school in lancashire. This morning, her classmates at assembly sang, dont stop believing. Her mother and sister are still in hospital. She was loved by everyone. Her warmth and kindness will be remembered fondly. Saffie was quiet and unassuming with a creative flair. Saffie comes from a close, loving family and we can only imagine what theyre going through. Marcin and Angelika Klis from poland lived in york. This photograph was taken shortly before the attack. They had come to collect their daughters from the concert. Their girls lost both parents in an instant. Ive been a Deirdre Barlow super fan. Shes always been my favourite character. This is martyn hett speaking to the bbc in 2015. He was 29, gregarious, full of enthusiasm. His partner wrote, our wonderful, iconic and beautiful martyn didnt survive he left this world how he lived, centre of attention. Kelly brewster was 32 and from sheffield. She died shielding her 11 year old niece from the blast. Her partner wrote, kelly really was the happiest shed ever been. We had so many things planned together. Georgina callander had adored Ariana Grande since childhood and had met her. She was 18 and a second year student of health and social care, planning a career committed to helping others. John atkinson, who was 28 and from bury, also studied health and social care. One in a million, his friends said. Loved by so many. A true gentleman. Jane tweddle taylor was a School Receptionist and a mother of three from blackpool. She was waiting for a friends daughter. She is irreplaceable, her colleagues said, bubbly, kind, welcoming, funny, generous. Neljones was 14 and described by her teachers as a bright and popular pupil, always smiling. It feels like the school has lost a sister, they said, not a classmate. Sorrell was also 14 and from leeds. Her mother and grandmother were injured, her grandmother critically. Her sister survived without injury. Michelle was married with three young children. Herfamily issued a statement saying, family was her life, she has been taken from us in the most traumatic way imaginable. Friends lisa lees and alison howe were waiting for their 15 year old daughters. Both girls survived the blast but their mothers died side by side. Look into these faces and youth and optimism beam back at you. Children, young parents, leading normal, blameless lives. Alan little, bbc news. And this is what is so heartbreaking after the attack, too many children, too many families devastated by the bombing. It is terrible. Notjust the young victims who weve heard so much about in the last few days, but 14 of the 22 have now been named, it isa 14 of the 22 have now been named, it is a complex thing to name everyone who has been killed and that is proceeding. But what we have so far oui proceeding. But what we have so far our young people who were at the concert but also parents who were waiting in the four yay for their children to come out. We all know what that is out, those of us who are parents, you go, you get as close to the venue as you can hoping you can catch a imp libs of your children as they come out, and that is when the bomb went off. Goodness knows what must have gone through the minds of the children coming out, some of them certainly lost their parents. Some were mothers, one case i have read about today was to mothers are standing together who we re to mothers are standing together who were going to pick up their two daughters who went to the concert together. It is heartbreaking, but it always is with these attacks. There are always stories that touch you. In response to the attack the Terror Threat across britain has been raised from severe to critical, it means is further attack may be imminentand it means is further attack may be imminent and troops have been deployed to key locations across the country. Joining me is a Senior Lecturer at the University Of Sa Lfo Rd , lecturer at the university of salford, specialising in psychotherapy and counselling. We we re psychotherapy and counselling. We were just talking about some of those Heart Rending stories. These flowers, and all these people that are here tonight, for those who have lost people, does this make a difference . Im sure it must be an incredible comfort to know that hundreds of thousands of people are supporting them and entire communities are behind them. The thing we know that makes the most important difference to people who have experienced trauma is social support, which comes from family, friends, colleagues, peers, classmates, but also from the wider community. So this must make them feel very cared for. How does it change the psychology of the city . I am from the north, some of my northern friends said we used to think that all Terror Attacks were focused on london, and they are nervous about the tube in london, but now they realise it can happen here in the most ordinary place. But now they realise it can happen here in the most ordinary placelj am here in the most ordinary place. am not so sure about this, because manchester was bombed back in 1999. And a lot of people in manchester remember that. What has happened in the last few days has really reminded them of that and brought a lot of those memories back. Think a lot of those memories back. Think a lot of those memories back. Think a lot of people in manchester had a sense for quite some time that we we re sense for quite some time that we were a potential target, and now this brings it very much alive. I think it is possibly going to make ita think it is possibly going to make it a bit nervous and apprehensive for some time to come. Thank you very much. They will be very assured a little bit by the Police Presence in the city, it is very noticeable. We havent seen any soldiers but there are plenty of armed police. Well, christian, here in new york security is always at the forefront for public officials. Today i spoke with richard clarke, who served in multiple administrations as a white house Counter Terrorism official to get his reaction to mondays attack. Terrorists look at attacks and learn from them. Intelligence Services Also learn from them. When you look at what happened in manchester, what strikes you . It shows us that you can have really good security around a venue can have really good security around a venue and in a venue, but there is a lwa ys a venue and in a venue, but there is always that area right in front of the venue where people pile up. Whether it is the counters at the airport before you go into the security zone, or the area outside the concert hall when people are pouring out of the concert hall. You cant secure everything. You cant secure everything, but that is sort of the option we are looking at, isnt it . If we want to make people save they are will have to have increased security in public venues. They will have to have that, but they will also have to get used to greater eloquent eczema railings. Here the goal is to catch the perpetrators before they put the bomb together. Before they moved to the venue. When the bomb is on the way to the venue it is already too late. Is isis hard it to combat them alqaeda was. Archive was centralised. Isis shows a way of being decentralised. It is very difficult to get these people who are self activated, who turned from being just radicalised one minute to being just radicalised one minute to being martyrs the next. There are reports that this individual travelled, he was of libyan descent, travelled, he was of libyan descent, travelled to libya and perhaps also syria. Would that raise a red flag for you . Certainly the fact that he had gone to libya and syria would have put him on a watchlist. That list does not mean what people think it does. It does not mean there are scotla nd it does. It does not mean there are Scotland Yard guys following him around all the time it means he is on an electronic watch list. To actually follow someone 24 hours a day takes over 20 people. You cant do that when you have ten or 20,000 people on a watch list. So realistically, Security Services in europe can never track the number of people who are potential threats. Security services can never track everybody and their watchlist. They can hope that they will find signals in electronic media, but they cant possibly know everybody at what they are doing. They arejust possibly know everybody at what they are doing. They are just on a watch list, it does not mean they are being watched. British officials have made it clear they are not happy that some intelligence that was given and shared with American Cou Nterpa Rts was given and shared with american counterparts was leaked to us media. How damaging is that kind of indiscretion . In this case it was not terribly damaging. American officials announced the name of the perpetrator of the Manchester Bombing before british officials. That is embarrassing, it is a slip up, it should not have happened, but it has no real effect. Donald trump said repeatedly they would drive the terrorist out. Can it be done . Driving them out implies using intelligence, Military Police to them. Thats fine, but you will do that for ever unless you get to the root cause. Which are in some cases socioeconomic, ostracise age and, in some cases the ideology and you have to counter that with a buy better ideology. That will take yea rs better ideology. That will take years yes. We have to live with this. After 9 11 president bush said this. After 9 11 president bush said this will take a generation. And i said no, sir, this will take several. We will talk more about manchester and the resignation but lets look at the other news today. The pope wants donald trump not to pull america out of the paris Climate Change accord. As a not perhaps so subtle gift, the pontiff gave the President A Parting Gift of his 2015 Encyclical Letter on the effects on climate. We dont know whether mr trump will be swayed by francis argument but he did leave the meeting at the vatican saying the pope is really good. Before they went in for their 30 minute private chat they posed for this official photo. The president at least looks very happy to be there. Iamjoined by i am joined by a congressman. He served as americas ambassador to the vatican during the bush administration. Do you think there is much the pope and President Trump can agree about . Yes. There is a whole lot they can agree about starting with the natural alignment of the United States and the holy see as being the two entities in the world that are squarely founded on religious freedom and the natural rights of man. We weather people that put in place the government Experiment Thatjohn Locke wrote about. Right, but. You will remember, during the cause of the Campaign Just how much these two disagreed, particularly on the issue of the mexican wall. When it comes to migration, Climate Change, theres not a lot of in common. think there may be some disagreements about Climate Change but there are disagreements on all sides of the issue. Disagreement is actually among scientists as to how reliable the models are that were contained in the international Climate Change group 2040 report. The essence of diplomacy is not to let your disagreements over come the opportunities to pursue common objectives where you are aligned, and we have many of those, the fight against islamic terrorism, the effort to protect christians in the middle east, to end trafficking of human beings, these are elements where there is an Enduring Partnership and we can work together. Would youll i could president to listen to the pope and keep america in the paris Climate Change accord . I would not want to give the president advice on what he should do. I think there are so many. You are a wise man. There are certainly debates on both sides. Thank you forjoining me. Im sorry, we have to leave it there for the moment. It was very interesting watching the photographs, they looked a little forced i thought going into the meeting. They looked much happier coming out. My suspicion is that even the president will have gone into the vatican and been just will have gone into the vatican and beenjust a will have gone into the vatican and been just a little overawed. What do you think . I suspect so for stop you know i was a former rome correspondence so know i was a former rome correspondence so i used to report on these meetings are not. There are these little codes from the vatican that tell you where you are in the pecking order. I remember in 2007 tony blair came to rome for his last visit with the pope and he was expecting to be given the red carpet treatment. If fact he was given short shrift because the pope, pope benedict, did not agree with labours attitude to game our edge, stem cell research, etc. He was rushed round the library and then had a very brisk conversation at the end. I experienced some of that because i went in to meet the pope after that and he said, the bbc and i thought oh no. But actually he listens to the bbc in the Second World War so we got on quite well. You are a name dropper, christian the temperature today was around 26 degrees or so this afternoon. It is likely to get even warmer over the next few days. It is certainly warmer than yesterday. Here we had much more sunshine and we have had sunshine across more Eastern Parts of scotland, Western Areas will enjoy the sun tomorrow. You can see the Clouds Billing into western scotland, parts of Northern Ireland as well, but very little cloud for england and wales.

Some cloud inland but very little around the coastal areas. Lots of sunshine, temperatures widely in the mid 20s. Generally warmer than today as it will be for Northern Ireland and much of scotland. Any Cloud Retreating back up to the Northern Isles into the afternoon. A lot of sunshine on the way on friday. The wind is coming in from the south or southeast, drawing up warmer air from the near constant, helping to boost those temperatures again. Probably peaking at around 29 celsius in scotland. Elsewhere widely into the maids to high 20s inland. A touch cooler around coastal areas. A Weather Front out to the west is threatening to bring Thundery Downpours into south west england, wales, scotland and Northern Ireland.

Police are carrying on their investigations here. There have been a number of
