We were just at that restaurant a short time ago where that american student was killed and right across the street that other restaurant where the car pulled up, they got out of the car, began firing in that restaurant. One more key factor that deputy mayor told me, theyve never seen a situation where seven attackers would be discovered they were wearing identical suicide vests. He was telling me this is a new front in the war on terror here in paris. And, dan and paula, i should tell you, the president now in turkey has once again said the u. S.

How are the people there dealing with these attacks . Reporter well, ive got to tell you, dan, the irony of this sunday is that it is a gorgeous day here in paris. A blue sky overhead and people have been lighting candles all throughout this city. But when i was standing outside those two restaurants in particular, paris police pulled up, not to disperse the crowd, but to instead hang up many posters on telephone poles and on the restaurants themselves saying, if you need any kind of counseling, Mental Health help that were here for you. This city is trying to collectively hug one another. Theyve never seen anything like quite like this dan. All right, david. Thank you. Well see more of you on world news tonight. Among the 129 dead weve mentioned her, a Young American student lost her life at the restaurant targeted in the attacks. Nohemi gonzalez was studying abroad for a semester, and matt gutman is at the scene for us this morning. Hi, matt. Reporter hey, good morning, paula. This is the french bistro where gonzalez was gunned down along with 14 others. I want to show you the sheer number of bullet holes that pocked the facade of this restaurant and shattered its glass. We know there are other americans who have been wounded in this attack. Their names have not been publicly released. [ sirens ] reporter amidst this carnage american blood mixing with that of parisians. Its horrible. Its like war. Crazy. Reporter nohemi gonzalez, gunned down at one of the four restaurants attacked.

Happy birthday dear nohemi reporter this video from 012 shows gonzalez celebrating her birthday with Close Friends and family. I feel lost, sadness.

Reporter speaking emotionally to abc news celia says they walked right by us. In Perfect French he said, you killed our brothers in syria and now were here. Reporter they were separated. We were climbing corpses, you know. Reporter climbing over corpses to get out. I was keeping thinking, i cant die here. Reporter and the reason they couldnt die here is because they had two daughters waiting for them at home, and they were not going to leave them orphans. I want to show you something that pretty much sums up the mood here in paris. Someone just moments ago left this note in english. It says, let your faith be bigger than your fear. Paula, dan. Thanks, matt. Matt gutman in paris, and now an abc news exclusive. Hanna corbett and jack konda were just eight rows from the stage in that concert hall when the gunfire began and they managed to escape. We thank you both for being with us this morning. And i ask i got to ask when did you first realize that something was very badly wrong during the show . So coming towards the end of the concert and we heard this crackling noise like firecrackers, and then we realized well, i realized that something wasnt right and it wasnt part of the concert when the lead singers face just dropped and he ran offstage himself. I think people just sort of started dropping to the floor row by row, and as they did, we sort of just did the same, followed suit and thats when i realized. Jack, we understand that you actually moved to protect hanna. What exactly did you do . I dont know. Its a bit of a foggy memory, but i think i just sort of pushed hanna to the floor and lay on top of her essentially. You did that to protect her . Everyone was just hugging. Everyone was just doing that. Yes, yeah. And, hanna, what did you both do to get out of there . So, when the lights went on and there was no movement and everyone was just holding each other, that was a point where we thought that was it but then there was crawling towards the left of the stage where the fire exit was. I picked up on this, and we started to crawl ourselves. Some people were not moving, so you had to climb over these people which was a bit horrible and you had to climb over these people in the stairs where they piled up. So we were crawling and then we managed to scramble our way over these people in the stairs to get outside to the fire exit to the alley. Did either of you hear anything that the gunmen were saying or screaming as they entered the building . I as i say, its not something i remember clearly, but i dont seem to remember them saying anything, just the sound of gunfire. It was quite silent. That was quite scary. Yeah, after the initial gasps, i dont really think there was any sound other than gunfire. There was no screaming or anything, just silence and the hollow sound of gunfire. So, we understand that you are some of the first people out of that concert hall, but how are you guys doing after this terrifying ordeal . I can only imagine the emotions. Yeah, i think both still sort of taking it in. Just feeling very, very lucky and obviously devastated for that so many werent as lucky as we were. Yeah, its really heartbreaking really. Its really heartbreaking. Jack and hanna, we really appreciate your time this morning. Thank you very much, and we are glad that youre both okay. Thanks for having us. Thank you. Meanwhile, this morning the global investigation is under way, and, in fact, fbi agents are heading to paris. The pressing question, of course, who were the seven people who carried out these attacks, and abc news chief investigative correspondent brian ross is covering that angle for us. Brian, good morning. Well, good morning, dan. Authorities today are urgently seeking more possible accomplices in the attack and say they have now captured at least one member of the isis attack team who managed to escape before being found across the border in belgium. The suspect was captured in this neighborhood in brussels, belgium, home to a Large Community of syrian immigrants. Three people were taken into custody including one man who Authorities Say was caught on surveillance tape in a rental car used in the paris attack french prosecutors say there were three separate teams in the synchronize d attacks, each member well trained and wearing identical suicide vests. Officials also revealed that one of the gunmen at the massacre in the concert hall was a 30yearold french citizen who had been flagged as a possible terrorist five years ago, but never charged with a serious crime. They did not have enough people to follow all of the suspects on their list of people who have been radicalized and who may be isis supporters. Reporter according to greek authorities, at least one of the attackers came into europe as a refugee from syria, arriving at the island of laras in early october just five weeks before the attack. [ speaking a Foreign Language ] reporter an indication, Authorities Say, of a new effort by isis commanders to plan major attacks beyond iraq and syria. There is a specific unit on the Organization Chart of isis for external attacks for planning and carrying out attacks in western europe and in the united states. Reporter at the end of october, isis took credit for bringing down a russian passenger jet over egypt with a bomb. On thursday, isis claimed responsibility for a massive bomb attack in beirut, lebanon, and then friday, paris carried out by what french authorities now say was a wellhidden isis terror cell and for the first time the group produced propaganda messages about it in four languages, french. [ speaking french ] reporter arabic. [ speaking arabic ] reporter russian. [ speaking russian ] reporter and english in what sounded to some like an american or canadian accent. Indeed, this is just the beginning. Reporter authorities this morning will continue to use documents, dna and fingerprints to identify all of the attackers. In one case a detached finger found in the debris at the concert hall was used to determine the identity of a gunman who blew himself up, dan. The amount of sophistication here on the part of isis is extremely well planned. Brian, thank you. And a Disturbing Development in these attacks, a passport found next to the body of one of the attackers raises the possibility that he was a syrian who entered europe posing as a refugee. Now, critics have said that allowing free entry to hundreds of thousands of refugees risks making it easier for extremists to slip through the security net so lets bring in abc news consultant matt olsen in washington. Hes the former head of the National Counterterrorism center. Matt, good morning to you. Good morning. In light of the refugee crisis, we are allowing 10,000 Syrian Refugees into our country. Is that going to change in light of this development . You know, paula, i would not expect that that number so change. That is a relatively manageable number particularly when you consider the total number of Syrian Refugees, which exceeds 3 million syrians who fled the country. So what exactly will the vetting process be in taking these refugees into america . How can we feel safe here at home . The u. S. Has a very intensive process for vetting refugees. It can take as long as two years. It includes checking databases within the intelligence agencies, the department of defense, the department of homeland security. It includes interviews, the collection of biographic information, so its a very intensive vetting process. Of course, the issue is its only as good as the intelligence information and its difficult to get intelligence from syria. It is and you mentioned that massive wave of Syrian Refugees, were taking in 10,000 but there are millions. What is the u. S. Doing to help European Security agencies. Yeah, here the key is to cooperate and share information with our allies in europe to make sure that they have the latest information because the problem is not just the refugees, but its the flow of foreign fighters back and forth from syria to western europe. It is a crisis and there so many concerns about it this morning. Matt, thanks for joining us. This is going to be a big issue going forward. Thank you, matt and paula. President obama, meanwhile, speaking out this morning while at a meeting of World Leaders in turkey. Here is what he had to say. The skies have been darkened by that horrific attacks that took place in paris. We stand in solidarity with them in hunting down the perpetrators of this crime and bringing them to justice. So, this question this morning, does this mean the u. S. And its allies are going to step up the fight against isis . Lets bring in abc news chief Foreign Affairs correspondent martha raddatz. Martha, good morning. Good morning, dan. Curious to see what you and your sources are thinking this morning. Do you think these will provoke an escalation by america and its allies . I think there will be a strong response probably militarily by the french. The french have already been bombing in syria, going after isis targets, but they havent done very many. So i would suspect they would do more, but think about this, dan, back in february when the jordanian pilot was killed, burned alive by isis, the jordanians i was over there at the time. The jordanians really stepped up the air strikes but they gradually faded off and i dont think jordan has done an air strike there for a long time. Most of those arab countries are now concentrating on targets in yemen. So, if they step it up, the real key is sustaining this fight, sustaining these air strikes. Followthrough will be the issue. We are, as everybody knows, in the middle of a president ial campaign here at home. Some of the republican president ial candidates have been attacking president obama quite vigorously for not being aggressive enough on isis. Let me quote senator ted cruz from texas who said, i recognize barack obama does not wish to defend this country. So, are you hearing any concrete plans from
