you are in the "cnn newsroom," i'm brianna keilar in new york. >> and i'm jim sciutto in paris. welcome to our coverage of events in paris. the followup to the attacks here this week. but also many developments tonight. right now, terror sleeper cells may be on the move here inside france. a french police source telling cnn, sleeper cells were activated inside france just over the last 24 hours. police officers here have been

told to erase their social media accounts and to keep their guns close at all times. this new warning comes as paris prepares for tomorrow's massive unity rally, featuring dignitaries and leaders from around the world. we know that israel's prime minister benjamin netanyahu is here and the king of jordan and president mahmud abbas will attend along with german chancellor angela merkel and the jordanian king. meanwhile, the hunt is on for a woman personally connected to all three terrorists who launched attacks in paris this week. just into cnn, a turkish official tells us that hayat boumediene entered with a man with only the initial m. and boumediene was then tracked and this is crucial, by turkish authorities, to a location near the turkish-syrian border.

it was the expectation she was traveling to turkey to eventually go on to syria. meantime hezbollah's leader is condemning the terrorists. he says islamist terrorists have done more harm to islam and the prophet muhammad than anyone who drew a cartoon or wrote a book. let's get back to the big concern, though tonight, and that is those terror sleeper cells activated in france just as world leaders prepare to travel here to paris. my panel is here to discuss terrorism. analyst samuel laurent, and bob baer terrorism analyst, paul cruickshank. bob, let's start with you, if we can. security risks for tomorrow's rally in light of this new warning of terror cells, perhaps activated here in france targeting police in particular. how can paris prepare for such an event, a crowd of some million members of the public

world leaders, in light of that terror threat? >> well let me -- jim, let me take that apart and say the world leaders, i think will be safe. there won't be any cars near them. suicide bombers getting close to any of those leaders is virtually impossible. the police are at risk. very much at risk. it's clear that these people have guns and it would be very easy to walk up and assassinate one. that's -- and i think of the french are very right to be concerned about that. and as for the crowd, there's just absolutely nothing you can do about it. a suicide bomber with a vest things are easily made. these people know how to make it can do major damage and kill a lot of people and do major damage to france. whether that's in the offing who knows. >> that's one of the ironies of this threat right, that you have more police in the streets who respond to the threat. but in light of the nature of this threat targeting police in particular that would give in effect the sleeper cells more

targets, sadly. samuel you were the first to report this new warning going out to police in paris. there was something interesting in the warning. one, keep your guns close. that makes sense to protect yourself. the other part was to erase their social media profiles. to french police have specific information that terrorists here are using social media to find their targets? >> well definitely. social media now is part of the war. and we can even say there are three front lines. one in syria, one in iraq the other one actually in the streets of paris, as we saw with charlie hebdo, and the third on the web. and basically, social media has been exploding in the jihadi community. and it's a recruitment, but it's also serving to targets, especially journalists, which has been threatened and which are now, for example, talking about french journalists, one of them is under police protection for being too active on the web, and targeting too many french in

syria. therefore, yes, the web is getting very sensitive. and so therefore they are looking for police officers to be targeted randomly. obviously, somebody signalling is belonging to the police force, would become easier prey. >> it's interesting, because in the u.s. and canada following lone wolf attacks in canada on the military there, the canadian military advise members of the military to one take off their uniforms in public but also be careful in social media and a similar warning has gone out to some american military. to be careful about their media postings so they don't make themselves obvious targets for lone wolf attackers or others in the u.s. going back to our panel in the u.s. paul cruickshank, if i could ask you, the other major development today, in addition to the word of this additional threat to police is new information about hayat

boumediene who was part of those who killed those four hostages sadly yesterday. now we are learning from a turkish source she made it not only all the way to turkey but to the border of syria. is that a surprise at all or should that be expected that is where she would be going if she fled france? >> i think the working assumption would be she maybe would have had some foreknowledge of this attack. and that's why she skipped out of france boarding a flight from madrid to istanbul on the 2nd of january, and then flipping across into syria on the 8th of january, the very same day her companion killed a french female police officer -- one officer on the streets of southern paris. so it may be it's because she had some foreknowledge, but didn't want to be part of the plan and she wanted to go to syria, where she couldn't be arrested by western security services.

>> and just a reminder to our viewers, the french prosecutor revealed yesterday there were some 500 phone calls between hayat boumediene and the wife of one of the kouachi brothers who carried out the attack on the "charlie hebdo" magazine. paul cruickshank, bob baer thank you. i want to go to fred plankton who spent the day at the scene of the kosher restaurant following the developments in the hunt for hayat boumediene. fred what else have we learned today? >> reporter: well we have learned a wide array of things. this new information we've gotten now is of course very significant. and remember that the french authorities still, we're hoping to get their hands on hayat boumediene even if she wasn't here during the time the events played out over the past couple of days. simply because she is such a key

figure in this entire plot. because she could give them some sort of light or shed some sort of light as to what groups might be behind this. whether it was really al qaeda and the arabian peninsula, whether or not there were ties to isis. and whether or not the fact that now the french authorities are saying that apparently some sleeper cells have been activated, what exactly might be behind that. so she is still very much a prominent figure very much an important figure and the french authorities most probably are still going to try and find out where she is at this point in time. the other things that have come to light today, we have gotten more information as to what actually happened here in the siege of this kosher store, and there were some harrowing accounts of people who were inside that store. they say that ahmed coom dahly came in guns blazing, told people he wasn't afraid to die. people there who spoke to french media say they absolutely were aware of the fact and knew he

knew this would be his last day and made him more dangerous. there are heroic stories, especially of one man mentioned by israeli prime minister benjamin netanyahu who apparently tried to grab the gun from coulibaly, didn't do so and was shot 45 minutes later. and the muslim owner of the shop who hid people in a refrigeratation unit and those people stayed there for several hours. there are more details that come to light all of the time jim. but certainly the hunt for boumediene is certainly at this point still the highest priority even though at this point she might now be out of reach. who knows whether or not she is still in turkey or may have gone across the syrian border. >> is t seems the french police have been struggling not just to track her movements in recent days buts are also the agreedegree she was operationally involved.

why did police think she was involved not only in the shooting that took place, but also in that hostage-taking yesterday? what gave them that indication beyond her relationship with ahmedy cool coulibaly. >> she seemed to be part of the radicalization. it appears as though coulibaly and she visited one of the isis recruiters in europe on at least one occasion. there's photos of her and coulibaly in an area in france seemingly practicing something that looks like a cross bow training. she was wearing an acab. it may have been the case she was part of the plot as well. and the same thing you mentioned before. she apparently had a lot of contact with the wife of one of the kouachi brothers. that of course is also

something that seems to indicate all these plots were in some way, shape or form synchronized and makes her a very, very important piece of the entire puzzle, jim. >> thanks fred pleitgen. french police investigating the violence that took place this week and scrambling looking ahead, trying to prevent more attacks in light of a new warning going out tonight. brianna keilar some real tension here. i have to say, just as an american walking the streets here i'm so impressed by how the french people are responding. they are out living their lives as normal as they can, despite this threat. >> and that hundreds of thousands of them are expected out tomorrow for a unity march, as well. jim sciutto in paris, thank you. and we are just learning that despite his background police stopped watching cherif kouachi, the man believed to be behind the attacks in france. why is that?

we'll discuss, next. (son) oh no... can you fix it, dad? yeah, i can fix that. (dad) i wanted a car that could handle anything. i fixed it! (dad) that's why i got a subaru legacy. (vo) symmetrical all-wheel drive plus 36 mpg. i gotta break more toys. (vo) introducing the all-new subaru legacy. it's not just a sedan.

it's a subaru. for fastidious librarian emily skinner, each day was fueled by thorough preparation for events to come. well somewhere along the way emily went right on living. but you see, with the help of her raymond james financial advisor, she had planned for every eventuality. ...which meant she continued to have the means to live on... ...even at the ripe old age of 187. life well planned. see what a raymond james advisor can do for you.

both french and american investigators are looking at evidence that ties the kouachi brothers to al qaeda's yemen affiliate, as well as to isis. one of them said kouachi, was reportedly once a roommate in yemen of the so-called underwear bomber had tried to bring down an airliner over detroit in 2009. we're learning new information about terror suspect cherif cue koekkoek koekkoek koekkoek kouachi. drew griffin has the details. >> in 2005, cherif kouachi was caught by french authorities just as he was trying to travel to syria. in an effort to join the fight against american soldiers in iraq. in his own words, from a deposition in this 400-page court report kouachi describes

how his perceived injustices in iraq drive his hatred and willingness to die. i was ready to go and die in battle. i got this idea when i saw the injustices shown by television on what was going on over there in iraq. i am speaking about the torture that the americans have inflicted on the iraqis. kouachi is one of several men radicalized and recruited at this now demolished paris mosque. now incarcerated radical cleric preached hatred. according to court records, cherif committed himself to this idea during ramadan in 2004. he told his friends he was going to syria to fight. cherif says he came to the idea for jihad from benefit i can't hue long associated in france with supporting jihad and terrorism. the documents say when police

interviewed his accomplices they stated kouachi said he was ready to fire bomb and destroy jewish shops in paris. when officials confronted kouachi documents say he told police something else. that's not exactly what he said. i don't hide having proposed anti semitic ideas, but i would note that i never really would have done that. the documents said cherif said the wise leaders in islam called upon him and his friends and if they die as martyrs they would go to heaven. under a section called motivations of influence, the prosecuting documents say for him, kouachi, any place on earth where there is such an injustice is justification for jihad. what was going on in iraq was, in his eyes such an injustice. >> and drew griffin joining me now live to talk more about this. drew we're finding out just tonight that french authorities had monitored the kouachi

brothers for about three years. and then they stopped several months ago. why would they do that? are we able to figure that out at this point? >> i think once the dust settles there in france there is going to be an overhaul and a very strong look back at the intelligence. keep in mind this case we're talking about, 2005 through 2008, was the first case. three years later, two years later, this -- the fellow kouachi is involved again, arrested again, this time implicated in a plot to have a prison break for another terrorist. and with him arrested is coulibaly, the person who died in the store there. so there is a long history there. we know that this man may have gone to yemen. we know he has link to hatred and we know the french authorities were monitoring him. he was on the no fly list. they're looking at him up until about six months ago and then they just stopped. the question i have is why?

>> yeah. great question. there is this paper trail, and why was that at a certain point deemed to be innocuous or innocuous enough to stop the monitoring. drew griffin, great report. thank you so much. we'll be asking that question, do the recent attacks in france and also elsewhere show gaping flaws in how authorities monitor and track potential extremists. we'll discuss that, next.

the boston marathon bombing, the siege in sydney australia, and now the shootings and standoffs in france. three attacks carried out a killing spree despite being monitored by federal authorities or law enforcement. have these and other attacks exposed a gap in our counterterrorism measures and monitoring programs? joining us now to discuss, former cia operative, bob baer. we have retired delta force officer, lieutenant colonel james reese. and former nypd detective, harry houck. to you first, colonel, do you think it's time we rethink how we flag and monitor possible extremists? >> good evening, brianna. the -- yes, i do. i believe right now there is -- right now, what you have is you've got a lot -- you know we started this years ago.

we had a smaller number of people and we had a lot of people that could do it. now, i was listening before. we have over 1 million people on the watch list, and it really just turns out to be how many assets we have. and we have to be able to fund our law enforcement and our intelligence services to be able to track these people around the world, and we can't do that under things like continuing resolutions and continue to argue about it. >> yeah. continuing resolution being just let's do the budget we had before, and not really i guess prioritizing money for certain things. and obviously, this should be a priority. you know bob, when i wonder if when you have individuals who have inclinations towards extremism, and they're being monitored, are they aware they're being monitored? do they take steps to avoid that? >> oh absolutely brianna. they have read everything that was leaked by edward snowden. i understand that skype is not

safe. these chat rooms are not safe. they understand we have algorithms that run through their communications and the metadata and the rest of it. a lot of these people are very sophisticated, and just as our police have gotten better they have gotten a lot better as well. so what it comes down to is the really smart ones just go off the air completely and deliver messages face-to-face. and that means that the police have to have a penetration inside these groups which is very, very difficult, because these people are generally true believers and are prepared for martyrdom and not about to accept money to become a source. >> yeah, you're talking about informants. and that's a lot harder than monitoring someone's e-mail account or what they're doing on social media. i wonder harry, we're looking at what appear to be a number of recent events. and it's alarming. i think people wonder about in the u.s. if this is something, despite the fact the terror

level has not gone up. if there are more things going on behind the scenes here and if people should be really concerned about that. >> well i certainly hope so. because if there are a lot of things going on we should know about them. and our homeland security people should know about it. i'm sure they're going over all of their old intelligence for the last couple weeks, maybe months to see if they missed anything. although the -- there is no specific threat against the united states right now, i'm sure they're taking little extra steps to make sure that in the event some information, intelligence information comes in they make sure they go over to correctly. and to the t. and, you know hopefully stop an attack happening here in the united states. >> and, bob, should americans -- and not just americans, westerners people all over the world, should they be more concerned about the likelihood of an attack? >> i think we should be concerned. i think there's going to be an attack of some sort. i think we all agree, it's almost inevitable.

somebody is going to slip through the net. what we can't do is overreact. we simply can't go after the first amendment at that point, or start expelling people willy nilly or have mass arrests. this terrorism will always be a threat, and we should accept there is going to be some tragic losses. colonel, talk about that. because we've had these discussions. and it's depressing. it's the reality that you can't catch every terrorist. that you can't eliminate every threat. but there has to be something that can be done to try to minimize these threats as much as possible. >> brianna, i agree with you. and i think there's two things to look at. one is financing for systems, for our law enforcement and our intelligence agencies. for big data aggregation. that's number one. number two, something we can do

around the world with you know -- whether it's nato or the coalition fighting isis right now, is take away the safe havens that allow these folks to go train. and literally, right now, you can pick about five or six places around the world still considered safe havens that people who want -- who are extremists who want training in this can come back and start up a cell. we shut those areas down that would help -- i believe help this issue some. >> attack those safe havens. certainly a number of things that folks are trying to do around the world. but it's definitely an uphill battle. gentlemen, thank you so much for chatting with me. really appreciate it. bob baer lieutenant colonel reese and harry houck in new york. thank you, guys. coming up we're going to be talking about hezbollah. the u.s. calls it a terrorist organization, and yet hezbollah is saying in this case this extremism is actually doing more

welcome back. i'm jim sciutto, updating you now on developments in and

around paris this evening. the people behind the magazine "charlie hebdo" are promising to put out a publication wednesday despite the killing of their editor and several colleagues this past wednesday. the magazine hailed a staff get-together friday putting a sad but defiant face on their operation. one "charlie hebdo" columnist says his co-workers who died would not want them to stay quiet. they're planning to publish more copies than normal 1 million copies in fact. in other news the leader of hezbollah says muslim extremists do more damage to islam than any books or newspapers could. the head of the lebanese shiite group that the u.s. and european union consider terrorists. he spoke late friday in beirut. he did not specifically mention the deadly attack on a paris magazine office but said beheadings and massacres in the name of islam are more offensive

to the muslim nation faith than to drawings of the prophet muhammad. i want to bring in brianna keillar, also with me today in new york city. brianna, what's the news there? >> jim, thanks so much. we'll be right back to you in paris in just a moment. the president of france urging people there not to lash out against muslims, insisting the "charlie hebdo" killers and hostage-takers do not represent islam. and from around the world this weekend, observant muslims are making their voices heard online with anger, disgust and heartbreak that such violence was committed in the name of their faith. one reporter who lives in virginia shared her feelings in a cnn video message. she is conflicted about how to explain what happened in paris to her young daughter. and she says she is quote, just livid. and i want to bring her in now. she is joining me live. this is cnn i-reporter.

this message is very powerful and personal. why did these incidents in paris affect you so deeply. >> well they affect me so much because being a muslim i think it is so important that we represent a faith that is there to bring peace and harmony in the world. and not these extremists who are using this as their own propaganda to fulfill their own fantasies that you know something will happen or they'll end up getting something better. it is important as a modern muslim and for other modern muslims to come out and really stand against this kind of extremism. because all you hear about when you hear about muslims is this extreme people extremism. if there is someone who is speaking against them they are usually killed or threatened. i think it is high time for muslim community to stand up against these threats and say no matter what you do we're not going to stop and we are going to speak out against these

horrible crimes. >> so you want to create this conversation. certainly we're doing this by having you on right now. but how do you do that? as you're saying that other muslims need to go out and talk to people and need to start these conversations, and really sort of explain themselves so that people understand this religion better how do you think they should do that? >> okay. so i think there is always a lot of conversation about the political system or changing the political system. there is not enough conversation going on about the grass roots movement. you know what can we do what can the communities do by looking inwards? not just through, you know community building or conversations with maybe other government agencies. but within the community. and say take measures to make sure that the communities are secure and if there is something or someone who is trying to harm that we notify the proper

agency proper authority. a lot of times, i've seen in my own community that there is a lot of dialogue maybe sometimes that you know is this right or is this wrong. but then there is no movement afterwards. i think a lot of grass roots movement needs to get started. a lot of conversations do need to happen online. i have so many friends and family that are always against these kind of things. they will talk about their fear sometimes that they don't go out because they are scared what will happen. my husband and i had this conversation before i came on that we have a 6-year-old daughter. should i be going out and speaking these things. and, you know, we came to the conclusion that at this point, we absolutely have to. we have to stand up and we have to say that this kind of extremism does not represent us does not represent our faith. >> we certainly appreciate you coming on zunera and telling

us your opinion on this. you were very touched by what you saw happening in france all the way in virginia where you were from. thanks for being with us. >> thank you. >> zunera mazher with us there. and one of the things investigators are looking into when it comes to the suspects in paris, their past. they're trying to figure out which groups they may have been affiliated with and not just how they kept off the radar, but really how they fell off the radar that they were once on. we'll have that ahead.

welcome back. i'm jim sciutto in paris. french investigators tonight are hammering in on the terror connections of the kouachi brothers and ahmed coulibaly. the three men claim they were part of either al qaeda or isis. joining me to discuss the men's ties former cia operative and cnn national security analyst, bob baer. and here with me in paris, cnn terror analyst, samuel laurent. bob, if i could begin with you, we talk a lot about not only the divisions between isis and al qaeda and the arabian peninsula and other groups but also the competition between them. when we look at attackers like we have seen here in paris in recent days are there sharp divisions between those groups and their loyalties to those groups? >> well the loyalties are one thing. but let me get into divisions.

aqap is externally focused attacking the west attacking airliners. isis at this point is more concerned with defending its capital, mosul, establishing an islamic state. i think there are divisions. but i had logically, for my liking they're the same. they're jihadists, go back to a philosophy 11th century. and using violence is the main tenent of their faith to establish islam. so if we see going back and forth people joining isis and then going to aqap it wouldn't surprise me at all. and i think this is happening as we speak, and will continue to happen. >> if i could bring you in samuel laurent, as well. bob makes the point that listen both these groups even though they have some

competition, divisions, different leaderships, different home bases, they have both encouraged their members to carry out attacks abroad against western targets. from the french perspective, do they consider either aqap or isis a bigger threat or do they look at them as really part of the same threat? >> well actually obviously, part of the same threat. but i would say that nowadays france is considering a much bigger one for a very simple reason. the jihadis nowadays are popping up literally speaking every day, and they are flocking into syria, because the turkish border does not require even a passport for french citizens to travel there. so we have hundreds and hundreds of french which are basically traveling there, getting battle hard and coming back. and obviously, targeting some individual assaults individual terror attacks, like we saw in december against christmas market, with the stabbing of a policeman.

basically, same procedure that we saw in australia and canada for example. so obviously, the threat was more immediate. but definitely the old style -- i would say structure of either cells, are representing a threat that is bloodily coming back. >> a reminder to our viewers, the attacks this week certainly not the first in france. there were other attacks in recent weeks and months. bob, i received briefing from the cia almost a year ago now. and they made the point the new terror threat is much more disperse dispersed, a greater number of groups more diverse, more spread around possibly with less ambitious plans, but a broader plan and therefore more difficult to track. are we seeing the expression of that now in these attacks this week, and this new threat against police officers in france? >> oh i think so. i think the cia was right. it's the strength of weak links. you don't want to centralize

command. you don't want to go to mosul for permission. you simply get the training and tell them generally what the attacks are, but you don't have to target a particular policeman. i guess the magazine was an obvious target for them but it didn't need to be coordinated every day. and so you get to stay off phones and the rest of it. they understand this. and it makes it much more difficult if the commander, the leadership is dispersed to go after. groups that are difficult to comprehend like the khorasan group. who do you align with? i agree with laurent, the islamic is a magnet to get the training and come back and make isolated attacks, which can undermine our security and our liberties. >> and good you mentioned the khorasan group.

we don't speak about it as often as aqap and isis, but when the attacks started in syria, you may remember american officials said the khorasan group had plans in the final stages against targets on u.s. soil. so yet another threat to face here for the u.s. and for the west. bob baer in new york thanks very much for joining us. samuel laurent, great to have you on as well. as france faces these threats, synagogues are closing around the country. including the main synagogue here in paris. the french-jewish community on high alert tonight and going forward. we'll have more on that threat after this break. ♪ ♪ ♪ you're only young once. unless you have a subaru.

welcome back. i'm jim sciutto in paris. a new sign of the widespread impact of the terrorist attacks here in the french capital. a landmark synagogue shut its doors today for the first time since world war ii. the grand synagogue of paris closed because of fears it could be the next target of islamic

extremists. another calls it a mistake. >> we need to continue and show we are not afraid of this kind of terror. >> in what french president holland calls an act of anti-semitism, they killed four hostages yesterday. he was linked to the terrorist in the "charlie hebdo" massacre. president holland expressed solidarity with israeli prime minister benjamin netanyahu who wants france to beef up security. benjamin netanyahu is on his way to paris to participate in a unity march tomorrow. joining me is jonathan lawrence national security analyst bob baer and former nypd detective, harry houck. jonathan if i can begin with you tonight. you have in effect a dual threat

now. a clear terror threat to jewish targets in the city and country as we saw yesterday and the attack on the kosher market. but you have also had a number of reprisal attacks against islamic institutions. synagogues kabob shops. it's coming from both sides. how does a society counteract that invariable human emotion of revenge on one side but also the terror threat on the other? >> it's something we're familiar with i think, from the aftermath of 9/11 when we too had to come together as a country in the face of what was really a divisive polarizing act. and that's what the trick is here. to call for national unity the politicians have done that. they want to it get the mainstream parties together. right now they have for tomorrow's march. but not all parties will participate. some of them have decided to hold their own rallies, and that is not a great sign frankly. >> have leaders done -- of course i remember the moment after 9/11 when george bush

president george w. bush at the time, very quickly went to a mosque in washington to demonstrate, you know this is not -- does not represent the islamic faith. we are not against islam as we fight this war. have french leaders made similar gestures? >> yes. the good news is that for the last 12 15 years, since 9/11 french leaders have been reaching out to muslim community leaders, created a forum, and so they're very familiar with one another. and immediately after the attack you saw leaders from the french muslim community go directly to the "charlie hebdo" site to pay their respects, and that is something continuing today. >> tremendously important. we'll see a similar diversity in that march tomorrow. bob, seeing to counter terror officials in the u.s. one thing you hear from them frequently in recent months is about reaching out to muslim communities in the u.s. not only to show solidarity and openness but also to ask for help in identifying potential recruits for extremism.

how important is that in the battle to keep well the u.s. safe and other countries safe? >> jim, i think it's crucial. i mean we have to identify in a jihadist clerics in this country. i don't think there are many but if there are -- like awlaki awaky assassinated with a drone. whether they're getting a following. keep in mind let's not forget that france was attacked by frenchmen and in 9/11 attacked by foreigners. there is a huge difference. we are able to asim ate muslims much better than the french. the 5 million or so french muslims are in -- i've lived there for years. i wouldn't call them isolated but they're not as integrated as american muslims are. so the french have a very different problem and it's a much more difficult problem than we have locally.

>> it's a criticism i've heard. having spent a lot of time in the u.k. as well. a more insular muslim community there. harry, i wonder if i can speak with you. you say that france has an exaggerated tolerance of radical islam here. can you explain that? >> right. well basically, what i meant is the fact that they've created -- the french government has created an environment in these certain neighborhoods where they don't allow local law enforcement to come in. all right? and by doing that not only do they follow some of their own law in these locations, these no-go zones in france. so what happens is if we can't get local law enforcement in there and they have their own law they follow then we could wind up having anarchy in france. i think it's totally insane that the government of france allows two different sets of laws for two different sets of people. and so when they created this

environment, now this extremism could grow in that environment. why would anybody anyway leave a muslim country to come and live in france and live under sharia law? it doesn't make any sense to me. >> well jonathan france has taken other steps, including banning the wearing of the nikab, a muslim woman's headdress that covers their faces which was a step at the time very controversial, because france wanted to show its common values. did it not? >> yes, absolutely. in 2010, 2011 the country held what was called a national debate on national identity. and one of the main concrete outcomes was a ban on burkas. the thing is not many french women wore a burka. there were probably 1,500 total. this was never really a problem. but the issue of radicalization is serious and something the french anti-terrorism squads have been following closely. french intelligence is really -- is well-known for its case work on this. and it's something the u.s. relies on heavily. >> no question.

and as we know intelligence services are constantly learning because this is a relatively new process, this outreach to muslim communities, in particular to help identify and prevent recruiting for extremism and extremists. constant adjustment and strategy over time. bob baer harry houck, thanks very much for joining us in the u.s. jonathan from good old boston college, thanks for joining me in paris, as well. so who is hayat boumediene and was she in france during the attacks? we're going to get into the developments we learned today and more after this break.

even as hunt for the paris attack suspects was still under way, social media was already buzzing with pictures and words of support for the "charlie hebdo" victims. many changed their facebook profile pictures to this image, je suis charlie or "i am charlie." >> people around the world have been expressing their shock and horror over what happened. they have also been showing their solidarity. the hash tag that has been used and a rallying call around the

world is je suis charlie, and we are charlie being tweeted in french newspapers. also being tweeted along with that hash tag, are cartoons from very well-known cartoonist from chile and barcelona who put pen to paper as a tribute to those killed in paris. cartoonist david pope was among the first to tweet his cartoon as a show of solidarity. this was shared 67,000 times. we asked him whether he thought "charlie hebdo" went too far with their satire. >> nothing justifies the killing of innocents, the sort of arms we saw last night. i have a particular view on the cartoon, to focus on those in power, and those who would accede to power, like the extremists we saw last night.

and as a matter of fact on social solidarity. >> others too have been inspired by the bravery of the cartoonist at "charlie hebdo." many have been very moving. many others defiant. others have been political in their tone. all, however, have carried the same message. and it's one that "marie claire" magazine captured very simply in their cartoon when it depicts the strength of the pencil versus the gun. freedom of expression cannot be silenced many are saying online. while these are images that have inspired cnn i-reporters, many sending their drawings their cartoons, as a tribute to those who died. and i leave you with one of the most retweeted and liked pictures on instagram, and it is this heartbreaking one. this was posted by elsa wilinski the daughter of one of

those killed friday. it shows an empty desk where he used to draw. and it reads [ reading in french ] which translates as dad is gone. poignant words, inspiring so many right across the world. cnn, london. you are in the "cnn newsroom." i'm brianna keilar in new york. >> and i'm jim sciutto in paris. welcome to our international coverage of events in france. word today from the paris terror investigation that french authorities were watching one of the brothers who attacked that magazine office on wednesday, and were watching him for years. but they lost interest. several french officials told a reporter there that said kouachi was under government surveillance from 2011 until june of just last year. that was after he returned to paris after allegedly going
