Somewhere that police cant go . The National Lead. The u. S. Military branch coordinating the war against isis centcom watching their twitter feed get taken over. Hackers posting isis propaganda and what looks like pentagon documents. Then they threatened american soldiers. Welcome to the lead. Im jake tapper live in paris, france. We begin today with breaking news on the world lead. France still under its highest alert level monday. Now news that last weeks terror may, may have only been the beginning. According to the associated press, two French Police officials telling the a. P. That as many as six more terrorist cell members are on the loose. This after, over the weekend, when french authorities told cnn that a terror cell in france had been activated. Today as citizens here in paris are trying to get back to normal or at least the new normal going back to school and work there are painful reminders of fridays sieges. Families burying their loved ones jewish victims killed by Amedy Coulibaly. Investigators are looking into a video of coulibaly pledging his allegiance to al baghdadi the leader of isis. Today u. S. Intelligence saying they are reviewing the video but have no reason to doubt its authenticity. Administration officials also admit coulibaly had been in the terrorist data base for awhile. Thats a quote. But as police and analysts piece together how and why coulibaly killed five people its becoming clearer and clearer that his girlfriend may have spurred his conversion from smallbit criminal to deadly jihadi. Cnn has learned new details about the lethal romance of the terrorist couple at the center of the conspiracy whose savagery has stunned the world. It turns out Hayat Boumeddiene, believed to be on the run in syria, was the more radical of the two, according to the attorney for her boyfriend. Amedy coulibaly was killed at the kosher supermarket in paris after slaughtering four innocent jewish men. It was here where coulibaly began his evil rampage, murdering in cold blood a local rookie policewoman. Perhaps not coincidentally just around the corner just steps away from a local Jewish School. Today, that school was guarded by armed police. More than 18,000 French Police and military troops have fanned out across the country to protect vulnerable targets, including hundreds of synagogues and Jewish Schools. Its a crazy situation. The president of the school tells us he believes coulibaly intended to attack the school before he murdered the police officer. She was killed you know in the corner, you know. 200 meters, you know from the school. Do you think that the school was the target . Yes. Do you know that or yes. You think it . I think. We didnt talk for long. He had to run off to attend a funeral for one of the jewish hostages killed by coulibaly here at the Kosher Grocery store. We are being kept away from the crime scene by Police Barricades policemen and police tape but even from this distance you can see just how devastating the French Special forces assault on the terrorist was here at the supermarket, the kosher supermarket hypercacher. The walls and windows are riddled with bullets, one completely taken out. A photograph published for the first time today shows the horror that took place inside. This group of hostages including a mother and her infant daughter hiding for hours from the terrorists inside a freezer. They were worried that the child would not survive the hours in this freezer but somehow, they managed to communicate that to police who turned off the electricity, possibly in that action saving the babys life. Visitors here today prayed and lit candles for the dead. This mother jewish like the four victims here told us that france has changed. As a jew in france do you feel bad. Tell me. I feel very bad, because we have children we have to put our children in Jewish School because of our religion but now we are afraid. Now we have more reporting on coulibaly, having spoken to his former defense attorney earlier today. He was labeled by his own mother as a juvenile delinquent. Coulibaly was something of a run of the mill criminal convicted of Armed Robbery five times and drug charges once nothing related to terrorism. But then while in prison coulibaly met this man, djamel bag baghel an algerian terrorist. Beghal was serving ten years for plotting to blow up the u. S. Embassy in paris. According to the attorney beghal introduced coulibaly to Cherif Kouachi from the other terrorist group. Eight months ago, coulibaly was released from prison and went back into the arms of his even more radical girlfriend according to the lawyer. Coulibaly suggested that the arrests of the extremists im sorry. Coulibalys lawyer suggested that the arrest of extremists in december may have sped up the timeline for attacks. Now, in the chaos today, authorities initially thought that Hayat Boumeddiene may have escaped that paris supermarket scene, slipping through the masses with frightened hostages was the theory. Now that doesnt seem to be the case. There seems to be mounting evidence that boumeddiene was not even in the country. Cnn chief National Security correspondent jim sciutto is a few blocks away. Jim, authorities obviously want to detain this woman, to get intelligence from her. There is new video showing where she might be headed and it could seemingly shut down the possibility of apprehending her at all, right . Reporter well, no question. The lingering question since these attacks began on wednesday here at the Charlie Hebdo offices was were there other accomplices involved that got away or other members of a terrorist cell that helped them and are still at large. We got that answer today. The french Prime Minister confirming its highly likely there were accomplices. They are still searching for them. Meanwhile, one accomplice that we know to be tied to the attack at the kosher market escaped the country. We have video proof of that today. One of the paris suspects caught on camera on the run. This is Surveillance Footage showing Hayat Boumeddiene, wife of the kosher shop attacker Amedy Coulibaly, entering turkey from madrid five days before the attacks, accompanied by an unknown man, she hands her passport to an immigration officer and continues on her way. From telephone logs turkish Authorities Say she stayed in a hotel, then crossed into syria january 8th. One day before the siege. Today, french authorities made clear she is not the only suspected accomplice still at large. The complicity and networks and maybe finance also. I dont really believe in the idea of the lone wolf. Reporter which terror group, if any, ordered these attacks remains a mystery. Kosher shop attacker Amedy Coulibaly pledges allegiance to isis in a video circulating on jihadi websites with a chilling warning for the west. Translator you attack isis, we attack you. Reporter u. S. Officials believe at least one of the gunmen in the attack on Charlie Hebdo, said kouachi, trained in yemen with al qaeda in the Arabian Peninsula or aqap and may have met with one of the groups leaders, the radical american cleric al owl lackey before awlaki before he was assassinated in 2011. France remains on its highest alert level with france concerned that additional sleeper terrorist cells may have been activated. Translator the president of france asked the armed forces to help secure vulnerable areas of france due to the scale of the threats which exist for our country. Reporter the initial connection between the attackers at Charlie Hebdo here behind me and that kosher market it started as something very innocent. A group of young men who met on athletic fields to play soccer. That group grew into something much more dangerous, a number of them being radicalized. A great deal of attention focused on that group. There are more members still at large today and French Police have their work cut out for them capturing not just this cell but some 5,000 other suspected terrorists in and around the country. Jim sciutto, thank you so much. Lets bring in the chair of criminology at the National Conservatory of arts and crafts in paris. Thank you so much for joining us. Authorities think this woman, boumeddiene, may be in syria. Is that it . She gone forever . Is there any way to get her . There are various ways to get her. First, she may come back. Second you may ask by various way, syria to make her come back. Otherwise you go and try to catch her. In all practicality its a black hole in syria and iraq especially that area that is controlled by isis or other groups. It seems very likely even if you are talking about getting syria to help bring her back. The United States does not have the greatest relationship with syria. I think france has a much better one but still, not a fantastic one. Can they really be counted on to extradite this woman . No but theres a way for syria to try to make a gesture and say look we are fighting the same enemy and we are not the enemy you think, the enemy which is real is not us. Maybe in russia they say by the way, try to give the accomplice so there are various ways. Theres an apparent accomplice on that videotape with her. Lets talk about accomplices, because the French Police are now saying at least according to the associated press, that there might be six other terror cells, six other terrorists out there. French police told cnn over the weekend terror cells had been activated. The Prime Minister just told Christiane Amanpour that he does not think this was a lone wolf attack with just these four individuals. What are you hearing from your sources in terms of how complex this plot might have been how many other people may still be on the loose . In fact French Police is looking on the old cell the one this is ten years ago. This is a cell from a special neighborhood the kouachi brothers were in. This is where everything began. So they are looking on everybody else that was in this at this time maybe 20 21 members. When you say looking at them what does that mean . Looking at them arresting them trying to find them . They are looking at the address, looking at any connections they may have during the last few months with cell phones meetings connections, emails, whatever they may find they are looking at their files and try to make them speak. This is a huge net cleaning. What do you think . Do you think there are still terrorists out there that are part of this plot . Obviously there are people who wish countries ill in every country, but do you think people actively involved in this same plot that was inflicted upon the people of france last week is that still in flux . I think there may be some supporting members of this operation but i dont think theres more active members. But the real thing now is to find who is the real brain. We are now almost sure that the boss was coulibaly. You really think that coulibaly was the boss . That is now confirmed by coulibalys video himself. Now we want to be sure that hes the real brain and theres not somebody else that was there ten years or five years ago that may have let them do it. Thank you so much. Really appreciate your time.

Im jake tapper reporting live from paris. In our National Lead the United States military hit by a cyberattack from apparent isis sympathizers. Defense officials shut down the twitter account and Youtube Channel for u. S. Central command after strange messages began appearing online and the accounts profile was changed. Cnns Barbara Starr joins me live from the pentagon with all the latest. Reporter the claim is by those who are affiliated with isis that they conducted the hacking attack but that may be far from certain. Isis is already here. We are in your pcs, in each military base the hijacked Central Command account reads. In the name of allah, the most gracious the most merciful the cybercaliphate continues its cyberjihad the posts continue. But is this group the cybercaliphate really isis . It could have been anybody. It doesnt really matter that much that it was isis. It does matter that a Group Calling itself isis is taking credit for it. The goal here is to cause fear and overreaction. We need to react appropriately to it but not overreact to it. The fact that the twitter feed from centcom was hacked is not that significant. If the documents themselves were stolen from centcom, that is significant. Reporter the tweets threaten u. S. Troops and their families including posting the document with names and addresses of u. S. Military officials and documents related to north korea and china. American soldiers we are coming watch your back. We know everything about you, your wives, your children the hackers warn. The pentagon says so far, it does not appear anything classified was posted and one u. S. Military official said some of the information has already appeared online elsewhere. I can tell you this is something we are obviously looking into and something that we take seriously. However, just a note of caution to folks as theyre covering this story, this is a pretty significant difference between what is a large data breach and the hacking of a twitter account. Reporter the fbi is assisting the military with the investigation of the hacking of both its twitter and youtube accounts. Its the latest in a string of online hacks by people claiming to be isis. Last week several local media organizations had their accounts hacked and similar threats were posted. And all of this comes as isis in the wake of the paris attacks is also finding itself targeted online. The Hacker Group Anonymous says its targeting isis. Whats more concerning is not what they stole and posted its what they might have stolen and might be able to steal in the future. But this was a shot across the bow, basically saying we can steal things from you, take a look. Reporter the attack on Central Command came just as the president took to the stage to push for greater cybersecurity. As the hackers were posting the threats, the white house was sending out a message from the president on its own twitter account. If were going to be connected, then we need to be protected. And theres a couple of lessons here officials will tell you. First, this may not have been a hack into classified systems. Maybe it was just twitter and youtube but always that worry that hackers could get into the classified arena and military commanders again, always reminding the troops be careful about their social media presence. All of us be careful about what you do post online. Jake . Barbara starr at the pentagon thank you so much. Coming up this was the scene in paris yesterday. Leaders from around the world walking arm in arm in unity. Some critics asking where was president obama or joe biden or Mitch Mcconnell or john boehner . The white house doing some damage control today. Thats next. Plus they are condemning the terror attacks in paris while punishing journalists for speaking out back home. The double standard next. She inspires you. No question about that. But your erectile dysfunction that could be a question of bloo
