there is criticism for turkey the reason they want this safe zone is to keep kurdish militants out of it much more for that reason than to keep isis out of the zone and keep it safe. it's a very political concern and sure it's being discussed today. >> it needs to be said. it seems so simple to the uninitiated. they're in syria, let's go bomb syria. who's "we" and who's going to do it and everybody has competing interest in what's going on in an ever expanding picture of threat. that's the geopolitical nature of it and what the war against isis is. you have the investigation into what happened here. and the investigation is expa expanding from france to belgium, maybe logistical, maybe tactical as to what happened in paris, what do we know? >> reporter: we've got a lot more detail for you, chris, about the operations.

they continued overnight. this was the site of the first arrest. one man was arrested in public. clearly, they knew who they were looking for, didn't need to go to his house. a very surprised crowd that moved further up the street behind me with the support of the bomb disposal unit to target a vehicle parked outside another house where police also entered and made another arrest. we still haven't confirmed with police if that vehicle is indeed that black or dark gray. witnesses haven't been able to verify that fully, volkswagen seen at the site supporting the atta attackers. the mayor says this operation is not over yet, chris. it is conceivable she says all of this is part of the same network that extended into paris and extended for some time.

we were hearing from molenbeek since the charlie hebdo attac r attackers got hold of. >> yes. it is a repeat in terms of not just the impact but the large loss and the coordinated nature of it, the vest, the first time french had to deal with suicide bombers with vests that very well could have been locally made. the question of what happened here is obvious. what will be done about it is getting more and more complicated. we will take that on right after the break. please stay with cnn's coverage of what happened in paris. discover card hey! so i'm looking at my bill

welcome back to cnn's continuing coverage of the terrorist attacks, chriscomo with hala gorani. there has been a development found just now. let's get to fred. >> reporter: hi.

i'm just east of paris and the vehicle is of spanish make found by the police force where i'm standing a couple hours ago. i want to get out of the way. the police have actually towed the vehicle. you can see on the ground a lot of shattered glass, because the police officers when they got to the car and found three ak-47s. the big question, first of all, they say this is one of the cars that was used by the attackers on friday. the big question is did they drive it themselves or did someone else drive it here? how many attackers were inside the vehicle? judging from the number of xwug, they think there may have been more than one person inside the car. and they've been asking people if they saw any friday night and

no one saw any park the vehicle here and the gentleman next door said the only thing he saw was the police raid at 1:00 local time and saw the police officers break open the windows, search the car and fibreak the windows and tow the car away. this is one of the main clues the police officers have in their quest to find any one of the attackers who may have been able to escape the scene there on friday night, chris. >> thank you very much. now, obviously, as the investigation expands, there will be more and more resolve to do something about what happened here in paris and the question becomes what. >> that's right. join us now to discuss this is a spokeswoman for the french party here. what happens next year here for france. the president of france said this was a war, act of war against france. what does this mean?

>> yes. it was an organized act of war by a very organized terrorist military organization. we have to respond in kind. we have been very active in syria and why we were prime targets for isis. we have to act on several fronts now. we voted recently for french intelligence services of the means we can use for surveillance and these need to be rolled out. what we learned from the investigation in the next few days, next few weeks will tell us how to best implement those new laws so they're as sufficient as possible. >> you're saying we should react in kind. essenti essentially, do you think or does the socialist party believe in this country france should become more military involved in syria and iraq? >> this is definitely what should be on the table today. we need to do that with our allies. it needs to be an international effort. no country can act efficiently

on their own in syria. it has to be a concerted effort. we need to talk about also the transition. we know what happens. we've seen that before, we know what happens when we just bomb an area, not only makes it impossible for civilians, for collateral damage, to control collateral damage on top of that we need to have a political transitioning phase after we deal with the military. >> in going forward, you need to look back also. the criticism will be, why haven't you done it already? why have the french been slow to involve themselves in syria and slow to shore up their borders and deal with refugees here? >> when it comes to syria, france was the one that wanted to get involved in syria. in 2013, even before isis became a real threat. unfortunately he was isolated and couldn't act because we need to have international ground cooperation. >> there is no ground operation. what are the reasons for that?

>> no. because we need a coordinated effort for this to work. america knows that what happens when you go all alone in a country and your liberation force are seen as occupation force and this doesn't turn out very well. it needs to be coordinated, especially the arab countries in the area, also in the e area. we need to have an agreement with russia and iran about what the transition should be in regards to assad. >> do you believe after an attack like this there can be appetite in france for more of a ground force in a country like syria or in a country like iraq, in coordination with allies? because from the air, we saw it even in libya, when you have an air campaign that ends without boots on the ground, it doesn't -- >> actually, i think in libya, the biggest problem was the

aftermath, it wasn't just the fact there weren't enough boots on the ground, there was no serious political transition put in place and why there is chaos in libya and why we don't want this to happen again in syria. this is why this has to be thoug thoughtfully prepared. it cannot be improvised. >> you have what you tell your citizens to make them comfortable what you do abroad and you have what you need to tell them to make them safe here at home. they hear the sirens now. they need something different after in a tack. they hear the word islam and islamism and radicalism. they don't know which to believe and hear about refugees in human need and refugees who are actually terrorists. what do you tell them about how to understand the threat? >> french people are familiar with the threat of radical islam. they have for a long time, the first time we were attacked by terrori terrorists, radical islamists was 20 years ago.

this is something we're familiar with. what's changed now because we're at the forefront of the war against islamic terrorism all across the world but not just iraq and syria but also africa we know we have huge targets on our back. contrary to what happened, very targeted you said before contrary to the very targeted attacks in january, this is the realization we have to live with the threat of terrorism. just like americans, i was living in new york at the time of accept 11th and work -- september 11th and this is the realization you have to accept the threat there is this threat that could happen to any any time. >> the question is what response is effective? what refugee and political response, what type of backlash will they experience?

>> we have emergency decisions that were made for the next few days, maybe few weeks, so the investigation can move along as quickly as possible, especially in cooperation with other european countries. we see that with belgium right now. we know we have to increase our cooperation with the international level. france has been asking, pushing for a fully european solution in order to control, better control the european borders to process refugees a lot more efficiently with intelligence services so we can detect the ones that are not legitimate applications, and make it as hard as possible for terrorists to get into that means. >> let's see what happens at the g-20. the expansion of the threat is now painfully obvious.

the question is what will be the expansion of the response. >> thank you for being with us. up next, chris mentioned the g-20. we'll have a report from that summit in turkey, where it is taking center stage today. g day? ah, the usual. moved some new cars. hauled a bunch of steel. kept the supermarket shelves stocked. made sure everyone got their latest gadgets. what's up for the next shift? ah, nothg much. just keeping the lights on.

president obama saying the skies have been darkened by the horrific terror attacks in paris. that is a message being received here and around the world. >> and the g20 meetings occ occurring right now and mr. obama describing it as an attack on the civilized world and it is supposed to be a forum to discuss economic issues. of course, this will be the big topic of discussion, isis, and what happened in france. it is a two-day summit, which will be focused on this attack in paris. cnn white house correspondent michelle kaczynski, is traveling with the president and g20. tell us about the conversations the president is happening in turkey with his counterparts and elsewhere. >> reporter: that meeting with the saudi king was added after the attacks in paris happened.

this is overshadowing the summit and some of that is supposed to be economics. that will come up, too, a session on climate change and economic development and the dinner is focused on isis and syria and that was before the attacks. it has changed so much now. the words we're hearing from the administration was redouble and intensify the fight against isis, the question now is what is going to change if anything in the strategy against isis. the president was asked today, said i don't want to talk about it today and wait until the press conference tomorrow. if there is going to be news on that front, we expect it to be tomorrow when the president. this is the first time during this conference he will take questions from the press. it seems likely they will let the french decide what is happening. we know the french are working very closely with the u.s. and they have a general based at

sent com centcom. the u.s. is saying it stands shoulder to shoulder with the french on whatever they decide to do. it seems from what we're hearing from the sidelines that the obama administration will take the cue from the french in terms of how they want to respond specifically. the u.s. obviously will be very involved in that. what remains to be seen the big question is what will the president say about the u.s. strategy be in particular to isis. will that strategy stay the same? when you're hearing words like intensify and redouble, will we hear something like increase in the number of air strikes or will there be something added to the mix. at this point, the administration doesn't want to give detail. we're not hearing hints behind the scenes. we're waiting for tomorrow when we hear from the president directly. >> michelle kosinski, thank you for the reporting. whether we're dealing with geopolitics or anything in life,

words are as important but not as important as what you do. expressions of resolve and support and unity are with franch and parisians affected in this and those around the world as a part of this attack. the resolve is clear. what will be done and a pressing concern. >> and we now know the holder of the syrian passport found at the scene of the attack according to sources who spoke to christiane amanpour came in posing as a refugee. let's bring in the professor and chair of criminology at the national conservatory of arts and crafts. and also someone from our bureau. you have one name confirmed of one of these terrorists born as a petty criminal and it mirrors the profile of some of those who attacked charlie hebdo and the

kosher supermarket. >> yes. and in 1995, it was the first one who came from a criminal world and go to terrorism. we call them hybrids. after that, we had nothing since -- i and in 2012, it was a copycat. >> who attacked a jewish school. >> the jewish school was not his first target. the target was to kill french. he missed the first time and a bad coincidence. then we got the attack of charlie hebdo and the attempt at the jewish school again and killed a police woman. now, we have those guys. those are more complex because you have a mix of hybrids, maybe real terrorists coming to commit terrorism and only involved in that, not known by the police and intelligence services and maybe for the first time, those who are supposed to come back

from syria or iraq. >> what do you see as the shape of the response? once something happens like this, people want to respond in kind to what they saw as a threat. that means refugees can be a threat. that means once again, the motion that islam is a threat and you have this battle of words and meaning and perversion of faith. which way do you take it to be most effective now? >> criminals do work like doctors, diagnosis, prognosis and therapies. we don't begin with therapies because if we begin at the end with trying to cure what we are trying to succeed and terrorists for the last 15 years beginning with al qaeda to now. the question is to be sure this is the real issue. until now, 99.9% of those who committed attacks in the west were not coming back from syria, those we did not let go to syria first. maybe we can look on the real

and not last. do it as plurality and not singular issue. it's not something that replaces terrorism, something that had terrorism. we need to be able to do cust customized response and not ready to wear. this is the problem. >> it's always attractive to come up with a one size fits all. this is a complex situation. and joining us from the paris bureau, what do you make in the last few hours five arrests were made in belgium connected to the operations in paris. >> obviously, with the mounting evidence of an international team, dedicated to target paris, with people from france, and other countries, probably syria and turkey and here, this suggests the isis decided to

build up a team symbolically with many nationalities and also we see through the investigation, which is under way, there are many connections with other countries in europe, especially belgium. these need to be investigated of course. it's been suggested there have been contacts with these individuals and other operatives in this country. very interesting. this suggests an operation not conceived from our country but something built from outside, probably syria or iraq. we might be on the verge of more growing terrorist acts of this type in the future. some mix between -- >> so- - >> home ground here in france and people from the outside. >> so what change is going forward. right now, as we stand in the plaza republic, we see police walking around with long

weapons, unusual in paris. the idea of how to vet refugees differently given new information that at least one of these extremists had a syrian passport and came in with refug refugees. how do you balance the need for humanitarianism and to live your life with safety? what has to change, in your opinion? >> with this information we should still remain careful because the investigation is still under way. indeed, it poses a real issue, for me, the controller of the european borders. it is not only an issue with regard to immigrants, also an issue raised by france and other nations after the charlie hebdo bombings attacks in january, the issue of how we better control of the external borders and flow of individuals sometimes our own citizens coming back from syria and iraq, because today we don't have the tools to do that, to

control these individuals. we can control provision alley, the immigrants now but again, it's impossible for our own citiz citizens. nothing has been done. we're 10 months later and europe still hasn't changed the rules with regard to the border controls. the same way it -- nothing or only middle to better enhance the cooperation and exchange of information. >> all right. in our paris bureau, thanks very much. thank you very much for your expertise. that will do it for us this hour. thanks for watching. i'm hala gorani. >> there are new developments and new questions as we show you a live picture what's going on in france. the pain is real. not even a year since charl charlie hebdo is thrown into turmoil. what will be the response in the

investigation? cnn's coverage will be picked up with jake tapper after the break. i'm chris cuomo with hala gorani. stay with cnn. hello, i'm jake tapper in cnn and people still on edge and warning it may not be over and police all over the world are hunting many accomplices that may still be at large. one terrorist still being investigated, investigators found his finger on the floor where he blew himself up. his name is ismael mostefai. and some of his relatives are in custody.
