Ndent on the ground what do you know about the surrender or capture of one of the suspects . [ indiscernible ] we can see a number of armed Police Outside an apartment building. And it is quite calm right now. But a few hours ago they want in heavily armed. There were sharpshooters in the area. They went into a first floor apartment. For 15 minutes. We dont know exactly what they were looking for are weren the apartment for long. And still hoping to get more details on that. The youngest suspect appears to have turned himself in. Also atika, Police Released photographs of the names of other men they believe are involved. What do you know about that . They put out the names and helped others in iraq. Between 2005 and 2008. He was convicted of recruiting young men to go to fight in iraq. [ indiscernible ] le hours. Clearly he was somebody on their radar. All right, atika, stand by with our breaking new. Want to get back to Anderson Cooper with more on the investigation. Anderson first to you. You spoke to the filmmaker. We showed the video at the top of the show of this attack being caught on tape. What did he tell you about this . Yeah martin dubros journalist in the same building. Heard the shots. Ran up saw two of the gunmen or, one person in his office saw two of the gunmen. They ran up to the roof of their building. Thats when the video starts. And he was able to capture the sights and the sounds of it. Obviously this video has been very important. Not just to media covering it and people who are interested in it. But to Law Enforcement as well. Really getting a glimpse of the gunmen. Getting a glimpse of their tactics of their capabilities. Its something that Law Enforcement intelligence communities have been looking at very carefully over the last 14 hours or so. He also martin dubros after the gunmen fled he and others went into the offices of of the magazine and said the scene was obviously just one of of horror and, bodies strewn throughout the newsroom there had been a meeting of of the news staff, a weekly meeting, so whether or not the gunman knew precisely that the meeting was taking play at the time or not. They could not have picked a worse time to actually to attack. Or perhaps from their perspective. A better team to attack. So many people were gathered together. Just a horrific scene inside the offices. Can only imagine. You were at one of the demonstrations tonight where parisians gathered to show solidarity. Describe the scene, will you . It was very interesting, don. Over 10,000 people came to the square. On one hand the people were defiant. Freedom of the press is not going to be silenced in the country. For freedom of speech. Liberty which is something that is very important here in france. At the same time people were telling me that they felt heavy hearted. One gentleman who came up to me. Who used to bea journalist himself. The last time he felt this way was on september 11th 2001. Very quick to say he doesnt want to equate the two. 9 11 was so much worse than here today. He said the same very heavy, sinking feeling that he had as though almost part of this country had died. But at the same time, people were very very positivement people were saying that that they were going to continue with their lives. They would not allow terrorism to dictate the way they live their lives. What ive found really important at the demonstration. These were impromptu demonstrations. Called in very quickly. There was absolutely no antiislamic or muslim sentiment at demonstrations. Something very important. You had people here from arab community. Muslim community. European french people here, who would stand together. Not allow extremism from either side. Rightwing extremeism from one side. Or take hold of their lives. And define their lives, don. Awe all thank you very much. Joining me now on the phone is a journalist in paris and he knew one of the victims and ran to the scene. Thank you for joining us. You work nearby. You arrived about 15 minutes after the attack. I wantup to describe to us the scene in those initial moments. When i arrived there was a big, the situation was chaotic. There was a lot of police arriving. It was not clear what happened. You knew the editor. Some of the staff killed this morning. What can you tell also bout them . Well the magazine, it, well little circulation. But very well known. They basically respect no one and nothing. They make jokes about every religion. Politicians. About the police. You can name it. But they also. Theyre lack that. Thats their character. They were four years already. Since they published cartoons the prophet muhammad. Maybe because of the threats. But, usually had two bodyguards protecting him, is that right . Yeah thats correct. He was always acompanied by one or two secret service officers. Everywhere we went, for the last four years. And his bodyguard today was killed as well. And in action. Found it odd that he had two bodyguards with him . Yes, i used to participate in a debate on french tv. And i met him regularly. And i think, six months ago i saw him again. He was with two bodyguards. Two policemen. And, i found it odd. We were against journalists. Amongst journalists. There was no danger at all. But with hindsight it was naive to think like that. Unfortunately, even if he had had, had protection all the time it wasnt enough. Describe the shock that france is feeling right now . The shock is huge. Not only in france but ooh have seen reactions, of compassion in the world today. On social media. On television. And and of course journalists die in when theyre doing their job. In war zones. We read about that every day. When ten journalists are killed in the center of paris. It is no longer an attack it is an attack on freedom of expression. In germany for example. They have been dealing with a great deal of islamphobia recently. Are people expressing anger towards muslims after the attack. France is the largest Muslim Population in europe. 6 million people. 10 of the population. Of course when there are tensions in the middle east. You see tensions in French Society. But this has been going on for many years. But i its true that there is a couple of actually about a year. With the aye events in iraq and syria. The positions are becoming harder. There is much more security in the streets of paris. People do speak out against immigration, against muslims. And, yeah thats a very worrying situation. You said it is an attack on freedom of expression and journalism. Should they continue doing what they do . Of course, we should never cede to extremists to cowards who want to kill any form of freedom of expression. Its its a tough job, but you know we should not should not surrender to these kinds of threats. We should not be afraid. Of course they should have the right to publish everything they want. It is a free country. Freedom of speech. Nobody should die for that. And that is something we should fight for every day. Stefan devries. Thank you. Yours welcome. More breaking news. I want to bring in cnn pentagon correspondent barbara starr. You have information on the suspects. What can you tell us . Good evening, don. French officials apparently had the identity of one attackers known to the United States. U. S. Law enforcement telling evan perez that the u. S. Was aware, some time ago, of the identity of who turned out to be one of the perpetrator tuesday. One of the alleged perpetrators. The u. S. Became aware of this person through french authorities. They had the person under surveillance. So it is raising the question if he was a known entity how could he have pulled off this attack. What the indications are is while he was under surveillance not a tier one target if you will not a top terrorist threat. So perhaps very difficult to maintain constant surveillance over this person very manpower intensive. But none theless, now what we are seeing for the last 14 hours or so is u. S. Intelligence Services French security and intelligence services, sharing all of the information on the suspects. Combing through everything they have. Emails, telephone intercements seshl social media, communication, imagery, messages. Every scrap of material they have to see if they can put together essentially think of it as the a pattern of life. Communication trail, interactions the suspects may have had with other people and other places. Big questions where did they get their training weapons, Planning Organization went into this attack. So they want to not just catch the guys. That is urgent. They want to find out afrg they scan about them. Where they went. Who they knew. Don. Barbara, the president of the United States barack obama offered any assistance to french authorities that that we could do here in the United States. A lot of this is manpower intensive. Does the u. S. Have any role in this . Well it is that cooperation there is very close cooperation between u. S. Intelligence services and the french. Particularly on the counterterrorism and Homeland Security front. This is something that the u. S. And french have been cooperating on. Because of foreign fighters going to iraq and syria. Coming back to the west. Coming back to europe. France. Potentially on to the United States. A lot of effort to keep track of these people. Coordinate. And, and try and track where they are and how, how they are moving. So we have seen this cooperation. Extend in recent months. And very safe to say, that cooperation is around the clock now. As the they try and find these attackers. Thank you very much. Pentagon correspondent barbara starr. A whole lot to got to when it comes to breaking news tonight. Two suspects named. One in custody. Reportedly turning him self in. Plus heightened security in new york city. And around the world tonight. Because of this. We will talk to new yorks top cops coming up. Music. The getaway vehicle for all the confidence you need. Td ameritrade. You got this. Back with breaking news. One of the three suspects in the deadly attack in paris turned himself into place. Ap reporting he is 18 years old. In a statement posted on their website. French National Police are asking for information on two more suspects. Cherif kouachi and said kouachi warning both are armed and dangerous. I want to get to the international correspondent, live in paris, with the latest on this. Also frederick, we are seeing an increased presence of police in paris tonight. Yeah you are absolutely right. One of the things on the streets here. I was roaming out here. As you said in some demonstrations in support of the magazine from which the people were killed. And you could see out on the streets here there was more police than usual if you, are in paris frequently you dupe see a lot of police on the street. But you dont see them as heavily armed as they were today. It was very interesting to see for instance on the main boulevard here in paris, you saw cops walking around. All of them had high powered rifles with them. Because it seems as though one of the thing that might have happened in the incident on the ground. Attackers were there for part of that. A shootout with police the police was overpowered. Using high powered assault rifles. The police had pistols at the time. You saw more police on the ground you saw police that was more heavily armed. Clearly bracing for something, fearing that other attacks might happen. Of course in the aftermath of the one that happened on the magazine. So certainly i wouldnt say, that there is an air of fear here in paris. But there certainly is concern. And there certainly is a bigger presence of law enforce. On the ground and they are more heavily armed. Thank you. Joining me now, William BrattenPolice Commissioner of new york city. And Deputy Director of counterterrorism. Commissioner bratten you have taken terrorism steps here in new york city the what are they . You increased presence . Thats correct. Literally almost upon the hearing of the events in paris. We benefit by the fact that we have a detective assigned there full time. Throughout the day we have been getting information from him. He is very close working relationships with the, the French Police services. But almost immediately that we activate activated plans we have in place for these types of incidents in which we have Critical Response vehicles crv, transitioned in manhattan, can be moved around in the city quickly to provide extra security at various critical locations. So working with information about this attack in paris, we put that into place. We also have our hercules teams which many in new york are familiar with seeing around the city frequently. The heavily armed officers. We utilize to help secure critical sites. So it was a multilayered response that went into effect all most immediately. Upon learning of the event in paris. What is your concern of a copycat . Well it is just that concern. The copycat or or the the incidents involving terrorists in the past is that that often times they look to try multiple events. So there is all way that concern. So until we really get an understanding of whats happening in this case in paris, and even now, many hours, the events its not quite clear what happened. Who is involved. That we will always err on the side of caution. The benefit in new york a large police force, capabilities resources to put into play. We are able to move fairly quickly, comprehensively to secure multiple sites. And also benefit by a huge intelligence operation that commissioner miller directs that almost 1,000 people focused entirely on intelligence and terrorist activities here in the city. I can imagine the video taken on the scene will be helpful in the investigation. Commissioner miller what struck you about the video. Video of the gunmen. They hid their faces. They had a getaway plan. What does that suggest if anything to you . I think what was most striking from the video, from both an intelligence stand point and tactics standpoint when you look at the two individuals they have come prepared with with their tactical clothing and they have come with Tactical Gear including the magazine holders the weaponry but the most striking thing is the level of calm and through which they move through the event. You witness the execution of a police officer. You see them in their escape having already killed a number of people in the newspaper office. And what you dont see is panic. On the part of the gunmen. These are strong indicators this is not the first time they have handled weapons, not the first time they have been around gunfire. So as the officials in france go through the background of these individuals, as we look at the background of these individuals, within the u. S. Intelligence community. What we are looking for is where have they traveled . Where have they trained . Where have they fought . We will gather those facts. But i would suggest in absence of the facts, it is going to be fairly unlikely this was the first time they handled firearms or shot at people before. French police put their names out there on a website asking for information. And their pictures. Commissioner bratten, the fact that they knew who the commissioner bratton, the fact they knew who the individuals were early on does that tell you anything about their affiliation . One thing we know about the French Police service. They are very good. We liaison with them quite closely. We have a detective assigned full time in paris who has been there for a number of years. So we are well aware of their capabilities. And the fact that theyre as good as they are. And they need new work with lead. Very quickly that they might be given. A reflection of the capabilities and qualities of the police intelligence. Is your detective assisting in the investigation . Our detective from the Intelligence Bureau is certainly available to the french. This has always been clear to the french prefecture and police. Thats what his job is as a liaison post the broker between the nypd and french prefecture of police in paris if they need information we can supply it and that we have it and the same goes both ways. The idea that that our detick tich was on the scene today. That was later at the hospital. Had access to the peoplen the investigation. And was able to feed information as he got it in real time back to the Intelligence Bureau so that we could do the proper deployments. Understand the threat picture. And have the latest information as it was coming in was invaluable. At the same time we were getting information through the fbi and their legal attache. All of the communication was nearly seemless today. In a city with a target environment like new york city thats critical. Commissioner bratton, Deputy Commissioner miller. Thank you for your time. Thank you don. Thank you. Off awe thank you. Our breaking news tonight one suspect surrenders. Two are still on the run after the terror attack in the heart of paris.
