This mornings eye opener is presented by toyota. Lets go places. Welcome to cbs this morning. Britains Prime Minister says another terror attack could happen at any time in the united kingdom. Police in manchester, england, made three more arrests this morning in connection with monday nights bombing. 22 people, some of them children, died in the explosion. Local police now say they have identified all of those victims. Officials also say 119 people were hurt, 64 are still in the hospital. A british tabloid this morning claims to show the suicide bomber, salman abedi. Police are examining his ties to libya where his family is from. The British Government has raised its terror alert to the highest level of critical, meaning another attack may be imminent. Police say that the man who set off this bomb after an Ariana Grande concert may have friends who were planning another attack. Cbs evening news anchor scott pelley is in manchester right now and joins us now with the latest. Scott, good morning. Reporter good morning, gayle. The heightened state of alert has taken effect across Great Britain today. Thousands of soldiers are being sent to stand guard at local areas all around the country to free up Police Officers for counterterrorism duty. In london, Buckingham Palace cancelled this mornings traditional changing of the guard so the police could be deployed elsewhere. And Britains Parliament is now closed to all visitors until the security level is lowered. Mark phillips is here with the latest on the investigation. Mark . Scott, however tragic this bombing appeared at the beginning, at least according to the police it was simple. The bomber they first said acted alone. Now theyre not so sure. The police raids in the area around the home of the suspect have led to increasing suspicions that the manchester bomber may not have been a loan wolf. Salman abedi, whose picture now appears in british newspapers, had been considered a minor figure, on the fringes of Islamic Militant movements but not a dangerous one. He was born and bred in manchester to a family that had left libya in the 90s, but he had traveled back there lately and Security Officials suspect may well have traveled to syria and may have been more directly connected to the socalled Islamic State than they thought. The attack on the concert crowd of mostly young people appears to have come just a few weeks after abedi returned from his last trip, and Security Forces now suspect a connection. The area of Manchester Abedi comes from and where the police have been operating has been known as a recruiting ground for isis, with a dozen or so of its young people going off to fight in syria. The police raids here have led to the conclusion announced by Prime Minister theresa may to raise the security level. This means that armed Police Officers responsible for duties such as guarding key sites will be replaced by members of the armed forces which will allow the police to significantly increase the number of armed officers on patrol in key locations. There wasnt much in the way of security to be seen as mancunians got back to work, but the sense of living in a secure city perhaps always something of a delusion is gone. Raising the threat level to critical implies that the old definitions of these things that the authorities fear, that an attack may be imminent. In this case what theyre saying is they cant be sure an attack is not going to happen. In other words, scott, this bombing has demonstrated what the authorities dont know rather than what they do. Mark phillips, thanks very much, mark. The people of this city are showing an amazing amount of strength and resilience. Theyre reaching out to help families that lost loved ones in the bombing. Jonathan vigliotti is in Manchesters Albert Square this morning where thousands of people attended a vigil for the victims yesterday. Jonathan . Scott, good morning. The memorial behind me only continues to grow. This is one of several that have been set up throughout the city. Of the 22 People Killed in the attack, police are now confirming all of them have been identified and were now hearing from families who had anxiously been awaiting good news. This is my daughter, olivia. I havent seen her since 5 00 last night. A mothers plea for help only grew more desperate as her daughters absence continued. I just i need my daughter home. I need to know where she is. We shouldnt have to do this. Even if you think its her, just let someone know that it might be her, please. I just want her home. I want her back in my arms. But today Charlotte Campbell returned to facebook, her hope lost. Rip my darling precious gorgeous girl olivia campbell, she wrote. Taken far far too soon. Go sing with the angels and keep smiling. Mummy loves you so much. 15yearold olivia was among the thousands leaving the Ariana Grande show when terror struck. Concert goer Alicia Hattersley escaped from the chaos. I can just hear the screams and see the people running. People shouting wheres my mummy, i cant find my mum. I didnt know what to do. Last night as the scale of this tragedy continued to take shape, thousands gathered together at a vigil to remember those lost and to stand defiant against an attack on innocents. Many of the victims who did not make it out were teenage girls. The youngest victim, just 8 years old. Its really sinking in. Shocked. Manchester stands together, we stand strong and nothing is going to stop that effort. And some of those who did escape found safety and comfort in the arms of strangers. We spoke with one taxi driver who was in the area at the time of the attack. He said he saw hundreds of people running at him. He opened up his car and crammed eight people into the back of his van. Scott, he continued to make several trips throughout the night. Jonathan vigliotti in Manchesters Albert Square. Jonathan, thanks. Were going to have much more from manchester ahead, including the reactions of many people that we spoke to during last nights vigil. For now, back to all of you at the Broadcast Center in new york. Thank you, scott, in manchester. Cbs News Senior National correspondent Michael Morrell was acting Deputy Director of the cia. Good morning. We know the suspects parents were libyan immigrants and he had ties to isis. What stands out to you about him . The fact that he traveled frequently to libya. We know that isis is in libya. Once had a stronghold in libya, so its possible that he had isis contacts there. Its also possible that he traveled to syria. Theyre still trying to figure that out. So i think thats whats important. He may have come into contact with isis. So this may be more of an isisdirected attack than just a lone wolf self radicalized attack. From behind the scenes when they ray the threat level as they have, what does that exactly mean . Theres five threat levels in the uk. Since 2014 they have been at the second highest level because of all the isis activity. What they did yesterday was to raise it to the highest level. The reason they did that is because theyre not 100 sure that this guy did not act with a bigger group, that he was a part of a bigger network. Until they figure that out, its best to assume that he was and, therefore, that more attacks might be coming. Well see over the next couple of days whether he was part of a network or not. And what it means when they raise it to the highest level is that the military replaces the police in some of the most vulnerable areas, so thats what will change on the street. One of the reasons i think the story is so painful and egregious is that many of the victims were young girls and the bomber had to know that before he went in. Are they trying to terrify the people to the point to say we will take your children . Is that the message . Isis has said from the very beginning that women and children are part of the target set. That they dont make a distinction between men, women and children. I think thats what we saw here. So im not sure that he targeted because they were young children, but he didnt care that they were. On the battlefield in both iraq and syria, were seeing gains against isis. Does this kind of attack mean that theyre strong and that theyre continuing to be a huge threat . So we are making significant gains. Mosul will fall probably in the next several weeks. Raqqah possibly by the end of the year. But whats happening is i think two things. One is isis is saying to its followers around the world, dont come to iraq and syria anymore. Conduct attacks for us where you live. So thats becoming a stronger message. That may have played a role here. And then second is 7,000 people from western europe went to fight in iraq and syria. 2,000 have come home already. Some have died on the battlefield. But as they get squeezed more and more in mosul and raqqah, more and more are going to come home and that actually raises the threat level. You had to have watched former cia director brennans testimony yesterday. Whats your takeaway from that . So what struck me, charlie, is that the u. S. Government was concerned enough last summer about russian interference in the election that they had the cia director make contact with his russian counterpart and tell them to stop. And the russians clearly didnt. So my question is what did the Obama Administration do after that, after they learned that the warning had fallen on deaf ears. It appears they did nothing. It appears they did nothing. Mike morell, thank you. President trump just arrived in brussels for a nato meeting after his highly anticipated visit with pope francis at the vatican. The private half hour meeting this morning with a handshake. The president and the pope put aside their previous clashes to send a message of peace. Margaret brennan reports from rome on the president s overseas trip. Margaret, good morning. Reporter good morning. Well, the holy see visit caps President Trumps tour of the capitals of the three great m mono. This heistic vision. Pope francis and President Trump are two unique and starkly different leaders. Guards saluted President Trump and the first lady as they arrived for a facetoface meeting with pope francis at the apostolic palace. Mr. Trump introduced his sizeable entourage, including daughter ivanka and soninlaw jared kushner. The polite papal encounter was a sharp contrast to their clashes during the campaign. For a religious leader to question a persons faith is disgraceful. Reporter when asked about the border wall proposal, pope francis said it is not christian to build walls instead of bridges. Mr. Trump fired back. I dont Like Fighting with the pope. I dont think its a fight. Reporter the two leaders also have diametrically opposed views on many issues. We will suspend the syrian refugee program. Reporter President Trump tried to ban syrian refugees. While pope francis personally took in 12 muslims who had washed up on greek shores to rome on his papal plane. When asked about their upcoming meeting, pope francis said, quote i never make a judgment about a person without listening to them. After todays 30minute closed door meeting, the pope appeared to give a gentle nudge to change the president s mind on climate change, which mr. Trump has previously called a hoax. Presenting him with three books, including one he described as focusing on care of our common home, the environment. Mr. Trump gifted him a custom bound set of the writings of dr. Martin luther king jr. On his way out, President Trump told the pope that he would never forget what he said. Then the president and the first lady went on a private tour of the sistine chapel.

Nancy cordes is on capitol hill. Nancy, good morning. Reporter good morning. Sometimes these officials can be a lot more candid after they leave government and that was certainly the case with brennan on tuesday. On the other hand, a current top intelligence appointee was much less forthcoming when he was grilled about whether President Trump pressured him to downplay the investigation. I dont feel its appropriate to characterize discussions and conversations with the president. Reporter the director of National Intelligence repeatedly refused to say what the president asked of him and of nsa director, mike rogers. Have you talked about this issue with admiral rogers . I would like to withhold that question at this particular point in time. Reporter former cia director john brennan told a House Committee tuesday that he saw a troubling pattern emerge last year involving the Trump Campaign. And i was worried by a number of the contacts that the russians had with u. S. Persons. Reporter by last july he had set up an Interagency Task force, comprised of agents from the cia, fbi and nsa. I know what the russians try to do. They try to suborne individuals and try to get individuals, including u. S. Persons, to act on their behalf either wittingly or unwittingly. The former cia chief, now a private citizen, says he doesnt know where the investigation stands now. These are contacts that might have been totally, totally innocent and benign as well as those that might have succumbed somehow to those russian efforts. Reporter the white house seized on that comment saying the hearing showed that there is still no evidence of any russia Trump Campaign collusion. I saw information intelligence that was worthy of investigation by the bureau to determine whether or not such cooperation or collusion was taking place. Reporter the senate Intelligence Committee hit former National Security advisor, the fired michael flynn, with more subpoenas yesterday. They want specific documents from two of his businesses and if he continues to stonewall, they say he could be held in contempt of congress. Gayle. Thank you, nancy.
