Terrorism project. First to joe. When you look at information, yes, sensitive but according to pentagon nothing classified was posted. Yes . Right. I think thats an important distinction. Nothing classified has been released. Clearly its a major embarrassment for the United States government josh earnest after dress addressing that question down played it saying theres a difference between a larger data breach into the Mainframe Computers and hacking a twitter and youtube account. You have youtube and twitter hacked. You read things like american soldiers were coming. Watch your back. Youll see no mercy. Isis is already here. Were in your pcs in military base with permission. We wont stop. We know everything about you, your wives and children. It was afternoon centcom identified the account was hacked. The hackers and their affiliation have not been confirmed. Its important to say that. They did flood the accounts with the jihadist propaganda and publish what they came to be internal u. S. Military documents which turn out to be addresses and names and addresses of military personnel and their families which is the most troubling thing but nothing classified brooke. We also now apparently have heard from twitter saying yes it was a hack. No more comment beyond that. Joe johns you mentioned josh earnest talked about this in the white house briefing. This is exactly what he had to say. This is something were obviously looking into and something we take seriously. However a note of caution of folks covering this story, this is a significant difference of what is a large data breach and the hacking of a twitter account. All right david. How significant is this . I think it is significant. While we may want to be cautious and can note this is a twitter t account and not classified mainframe, we cant be dismissive. Weve seen these extremist have traction on social media platforms and gone from mobilize mobilizing recruiting and Cyber Attacks against the u. S. Government. That was the point i was asking you earlier in commercial. I said what are you most worried about . You said effectiveness on platforms such as social media. Your group studies this sort of things. You had been warning twitter for months this thing could happen. We had. We noted while extremism has been around a long time extremists seem to use 21st Century Communication tools more effectively than we are to spread their message and radicalized. Weve raised this message with twitter and the response has not been as urgent and comprehensive as we would like. Who would be capable . Theyre trying to track back to the genesis of the hack and see who this was. Here we go the cyber caliphate with words i love you isisaisis. It could be a must be of different people. Yeah it could be. The government and private sector themselves. One thing weve seen when we track identities of cyber jihadists, quickly they can change their profiles and handles. To your point of sophistication and effectiveness. Thank you very much director of the counter extremeism project. Now with perfect 20 20 hindsight, the white house admitted it goofed not sending a higher profile someone from the administration to that march in paris. While the u. S. Ambassador to france was there in attendance white house spokesperson josh earnest admitted the stature did not measure up. Look at the pictures here. This will be written in future history books and will not include the president of the United States. Take a listen. Some have asked whether or not the United States should have sent someone with a higher profile than the ambassador to france. I think its fair to say we should have sent someone be higher profile to be there. Cnn senior Political CorrespondentBreanna Keeler from washington. Youve covered the white house quite a while before your current post. When you heard josh earnest say essentially our bad, we should have sent higher profile. You dont often hear that. You dont hear that from this white house. You dont hear that from many white houses. This was a big deal to see this. I think it reflected in retrospect they realized this was not the right decision. We heard from secretary of state john kerry that a lot of this criticism, president obama or higher level official not going, was quibbling. The fact josh earnest came out and said what he said, tells you they realize now its not just quibbling. Theyre not being clear what the problem was at the white house, you look at who was there. Security concerns for these leaders is huge. That push this is argument to the side. There are a couple of things going on here. One, president obama while he obviously does things to deal with terrorism, this isnt the issue he wants to be fully front and center out there with. I think its fair to say. I think the really big thing here is a style issue. This is an example of this president , maybe not being comfortable at times makinge overoverwhich you aroverov making overtures. It shows the first instinct wasnt to go. These are the moments that president s and the president of the United States would want to be a part of. When you see that picture of these dozens of World Leaders linking arms. I was listening to coverage earlier. Jake tapper pointed out in the wake of 9 11, in the first two weeks of that happening, who was the first to come to the United States . The president of france at the time. Thats right. Just the importance of the relationship between france and the u. S. Going back to the revolutionary war. This is a big deal. Look at this image amazing and moving. The fact the president isnt there or that another top u. S. Official isnt there is very much a conspicuous absence. This was probably the best move of the white house to come out and say we messed up. They were obviously facing criticism and i think they realized it wasnt going to go away and a mistake was made. This rare instance of were getting criticized and criticism is warranted. Breanna, thank you. How the three blamed in the terror attacks are linked in paris. Theyre connected to this Jihadist Group that pay have started in a paris park. Were dig into their backgrounds and how this network fits together. It comes as investigators search for possible members of this sleeper cell. Also ahead, a story we have to talk about. Another terror group, boko haram, back here in the headlines. You know the story, the 200 girls kidnapped by militants months ago. Now you have 2,000 villagers reported dead. Those details coming up here on cnn.

With great taste and 100 complete nutrition, its the only one cats ask for by name. Youre watching cnn. Im brooke baldwin. Now this worldwide hunt for this female terror suspect. Authorities initially thought the Grocery Store gunmans girlfriend may have slipped out with hostages. That was first reported. It seems she may not have been in france. Given what they know about this 26yearold, authorities are on this frantic search to find her. Turkish media say this video shows her far right of your screen in the white. She has her head covered on her way to syria, arriving in turkey from spain january 2nd. While it may not beer t french Prime Minister says theyre sure the Grocery Store gunman had an accomplice. Investigators believe the trail may have started in a park in paris, continued throug prisons and ended in bloodshed in paris last week. The network was nicknamed after where members worked out. This park in paris with an aim far from its tranquil setting to send french nationals to fight american troops in iraq. An investigative journalist formally with france iii spent months on a documentary back to 2005. One of them according to her reporting, in an attempted Suicide Attack against u. S. Forces along baghdads notorious airport road. That was cherifs aim to be a martyr in iraq. He was not religious and drawn into radical islam and then to war by this man. He told them you have to discontinue your identity your roots. You have to know who you are. Its why they were listening to him because he was like a prophet for them, somebody who knew more. She spoke about the abuses committed. Kouachi never made it to iraq detained with six others in 2005. All as seen in Court Documents obtained by cnn in conjunction charged with conspireing to commit acts of terror itch. The common link among them. According to the documents, three men had travel in 2004 to iraqs leader. Kouachi told the court he was relieved he was detained and according to the interview with social workers, he said he was finished with so called jihad. In prison the real radicalization began. They were in prison with other hard liners including essential figures in the Al Qaeda Networks in europe. Algerian born jailed for plotting to attack the u. S. Embassy in paris in 2001. He became their spiritual mentor continued the work in some way initiated. Maintained these links between them in prison radicalized them even more. He was in direct contact with the highest Ranking Members of al qaeda at the time. This terrifying attack on french soil carried out not by returnees from syria, not by foreigners but by two brothers born and radicalized here in france. And here she is with us mow. Also Cnn National Security analyst peter berman. As im watching you in this piece connecting all these different dots im wondering if were talking about this group from within the 19th district in paris where they all got together. Im wondering how many others there are still out there. How many mobilized they are. Do you know . Reporter we dont. That is exactly what french authorities are trying to determine because as we have seen with the violence that took place here over the last few days whom they believe might be a potential threat is not necessarily who they are watching. These individuals that were responsible for the bloodshed, they were not those that french intelligence was tracking returnees from syria that may have fought along extremists. These are people that went into hiding opening an entirely new level of threat authorities need to try and determine. Effectively as one person was saying you dont know if the individual standing next to you in the street at this state has the capability to carry out this kind of violence. Then one of the other ten kals of the story is this other brother that traveled in 2011 before alawlaki was killed in the drone strike. This kouachi brother roomed with the famed underwear bomber. Could you just help us paint the picture of what this kouachi brother would have gone through, a typical day. I dont know if the word is terror Training Camp or school. What would have happened over there . Typically these guys who go to yemen, hook up with some kind of school, legitimate school sometimes to learn arabic and in this case he went over there to the underwear bomb tore brush up on arabic. He spoke pretty good arabic. He reached out to mosques in the capital of yemen saying i want to meet alawlaki. He said im interested in meeting you. You need to write an essay about why jihad is great which he did. That allowed him in alawlakis circle. We dont now how cherif got into the circle. Recommend presume it was a similar process. It was in yemen, probably supposedly to learn arabic but seeking out al qaeda and over a period of weeks or months he was allowed into the inner circle. We dont know if he met alawlaki. Im sure he did. He said alawlaki financed his terrorist career in one of the last statements he made while he was alive. Alawlaki remembering what ive read about him, he was described as a charismatic man. Bin laden said he was jealous of him. Do we know how many he helped finance to travel to yemen to potentially carry out these acts . We dont know that. We know even in this country, the Boston Marathon bombers were influenced by him two years after he died. The paris cell influenced by him four years after he died. The point is this guy, even in death, is being quite influential and this multiple cases around the world, he spoke in english. He shows up in lots of cases. Theres been two dozen in the United States brooke, where weve determined his writings or propaganda were people indicted in cases. He remains influential despite the fact he was killed four years ago. When we say the name alawlaki, he was american born. Thank you very much david and arwa. Appreciate both of you. Coming up another attack and scene so brutal. Thousands feared dead at the hands of boko haram. What are we learning about a child forced to carry out an attack there . Plus the twitter account for u. S. Central command was hacked. The startling details. Names and numbers that ended up being posted reportedly in support of isis. That is coming up.

Since the Charlie Hebdo gunmen were can killed in the man hunt investigators have pulled travel records. Officials believe both brothers travelled to yemen in 2011 as we were discussing. How mounting evidence points to links to both men and an american clericist alawlaki. Peter and i were just talking about that. Anwar alawlaki. When investigators heard this name from the gunmen there were flashbacks. He was a radical american born yemen based preacher who was the key influence behind many terror plots in the past five years. Boston bombing suspect tsarnaev told he and his brother were influenced by him. In 2009 a man killed 14 people at a military base after sending 18 emails to alawlaki. That same year alawlaki orred the underwear bomber to take down northwest flight 253 over detroit. After the london two bombings in 2005 2005 investigators discovered four suicide bombers were dedicated listeners to alawlakis radio sermons. If the kouachi brothers were telling the truth about his trip to yemen, it would have have happened three years ago. Alawlaki was killed in a drone strike in 2011. His footprint and legacy, as were finding out, seems to endure. Unlike a number of leaders of al qaeda such as osama bin laden, he was a cleric. Experts say he could present as a religious leader. He was found by so many to be so charismatic that even bin laden himself was jealous. Alawlakis father was a minister of the government and came to the United States to study at new mexico state when alawlaki was born. At age six, his family returned to yemen. He moved back to college to study for masters and education. He even preached at a mosque in virginia. Later he would use american english to speak to his western followers. Martin storm, a former jihadist who says he became a cia operative got close to alawlaki. He said he was extremely determined and motivated. His passion to take revenge on the west and spread jihad was it was his whole life. When president obama made the decision to take him out, alawlaki was rising in leadership of aqup al qaeda in the arabian peninsula, a hub for training. Theyre now pursuing a global strategy. Once they are trained, he will request all leadership of al qaeda that they return back to the west and wait for orders. With that in mind the fbi is become more concerned about isolated attacks by people in the west who may subscribe to alawlakis teachings beyond the brave. Coming up next on cnn, well take a closer look at the stunning hack today. It was the twitter account of u. S. Central command. How likely it was isis behind this . After criticism from around the world, the white house saying today, yes a higher profile official should have been in paris for that massive rally yesterday.
