Just two days after the deadly coordinated attacks on brussels. Investigators are scrambling to piece together the clues. Authorities identifying two out of three suspects caught on airport surveillance cameras before two bombs went off. On the left, Najim Laachraoui, he is a bombmaker and his dna was found in the home where the paris bombs were made skphrbgs next to him, ibrahim el bakraoui, and the third man still unidentified and now the most wanted man in all of europe. He dropped off a suitcase full of explosives near the checkencounter and fled. An hour later, a metro station near seven european facilities also rocked by terror. Investigators have learned khalil el bakraoui set off the bomb in the train station. One was sentenced to five years for prison for carjacking and ibrahim was sentenced to prison in 2010. This is what happened in the airport moments after the blast. A taxi driver capturing this chilling video filming as he runs into the departure halls to find his son who worked at the airport cafe, and thankfully he survives, and he stumbles over the debris, bodies buried underneath the rubble. A baby cries in the middle of it all. Alone. Her mother lays unmoving. Here, a single rose lays crushed, possibly a welcoming gift for an arriving passenger, and now a symbol of lives lost in the tragic terror attack. Outside bystanders coming to the aid of the injured waiting for medical assistance, and those who are able comfort the wounded, though many inside did not survive. As the investigation is come into sharper focus we are getting a glaring sense of the investigative gaps that led up to the horrifying events that unfolded here. We want to tell you that at this hour police raids are being conducted all across brussels, because as we said there are still fugitives out there. Police are widening their manhunt for them and anybody else who may have helped them. Our Cnn International correspondent is live with more. Fred, what you have learned . Alisyn, there have been raids on going not just today, but yesterday as well. I was at the location of two raids that happened where apparently they were looking for suspects here in the greater brussels area, and one of the other places that a lot of the police work is focusing on is where i am right now. This is the building that you see behind me was the main bombmaking factory for at least three of the terrorists who then went to the airport in brussels, and two of them, of course, we believe blew themselves up. We want to take a look at the building here. You can see up on the top floor, thats the apartment that they worked out of, and when police went into that apartment they were amazed to find some 15 kilograms, more than 30 pounds of highgrade explosive called tatp, which is the same type of explosive that was also used in the paris attack. The other thing they found was screws, which is of course something mixed in the bombs to make them more deadly and they found an isis flag, and they believe the el bakraoui brothers were here. Another thing they found was a laptop in a garbage can out in front of the building that seemed to contain Something Like the last will of one of the attackers, and it seemed to show him saying police was on to him and he was on the run and he he felt he needed to conduct the attacks as fast as possible or he would be captured by the police. Stay with us, if you would. We want to bring in our cnn senior correspondent, calista ward. One of the suspect said he is no longer cooperating with the authorities and wants to be extradited to paris for the attack, and i am sceptical when terror suspects claim things or their attorneys, but what does this mean . Up to this point, one of the paris attackers, abdeslam, he was trying to avoid extradition to france. Now he changed his mind and decided he wants to be extradited to france as soon as possible, and Salah Abdeslam himself was not present but he has been charged with terror offenses, and there was a clue, and his lawyer said he is no longer cooperating with the police. The question i have to what extent was he cooperating with police before, because these attacks happened just days after he was captured. How could he announce it was the french that announced that, not the belgians. I couldnt tell if they were trying to curry sympathy with the public that he was cooperating and then he got in trouble with that for his network and now say he is not cooperating, and its hard to know what is real. What we do know, that information that he was cooperating likely precipitated these attacks because the rest of the network felt the noose is tightening and we need to get it done. You had a chance to speak to the principal of one of the suspects. What did you learn . Reporter one of the interesting things we have been finding as we have been investigating all of these attacks that have been going on is that in many cases a lot of these people have local roots. Right now i am in the district of scar beck. Only a mile away from here, less than a mile away from here, is the place where Najim Laachraoui went to school. We were able to speak to the principal of the school and its a Catholic School he went to and she said he was a fairly regular student and somebody that doesnt have disciplinary issues, and he went to the school until 2009, and after that was never heard by them as well. The fact that this man was part of the plot has shaken them here, and it underscores the local roots that a lot of the plots have. If we look at Salah Abdeslam, he was captured only a block away from where he grew up, alisyn. And we went there yesterday and i will show you what we learned. Lets talk about the manhunt that is under way for at least two fugitives. Authorities have not put out surveillance photo as who they believe was part of the subway attack. Part of the issue is, authorities it appears to me from our conversations authorities have not yet pinned down if he is alive or dead, and is it our benefit to release this information out to the Public Domain and they are hunting for him. They believe the airport bomber is still alive and they feel he left the suitcase and we dont know a name, we see a picture of him in the white hat and jacket. And the fact that he was wearing glasses and a hat could indicate he was trying to disguise his features and you see the other two men each wearing one glove likely use to disguise a detonator, but the man in the white jacket who is still believed to be at large was not wearing a glove and that would appear to indicate he was never planning to blow himself up. At this stage, the authorities really giving people mixed messages, on the one hand trying to show they are being proactive and the investigation is ongoing and they are making progress and showing very Little Information to the public. If that was a disguise and he was planning to flee the airport does that suggest a new mo for this type of attack . It mimics what Salah Abdeslam did in paris. That was part of the false trail. He claimed he had a change of heart. That was the first information that came out of the interrogation, and then the french Authorities Say we believe he was headed to another attack site, so they realized the propaganda value of having these people out there and talking about how they cant capture them, and this is what they were trying to replicate what happened in paris happened here in brussels. If they were a bombmaker it would not make sense to blow themselves up, they would have to live on to perpetrate a crime another day. When we talked about Najim Laachraoui being identified as one of the terrorists, and he may not have been the bombmaker in chief, and we are talking about things you can get that is in hair bleach and nail polish remover. Is the thinking still that suitcase bomb that didnt detonate and had a huge amount of capt in there that it was sophisticated or not sophisticated . There seems to have been an evolution in his skills set. You remember the france bomb, only one person killed in the bombs, and thats where he was then and now you have seen a more stabilized and sophisticated bombmaking skill set, and as clarissa was saying, it doesnt make him a master bombmaker. Information develops every hour, and you are working your sources constantly and we will check back with you throughout the program. Thank you very much. Lets get back to new york. We are learning more about the missing and injured in the attacks in brussels. An american couple living in belgium are among those still missing two days after the terror attacks and imagine what its like to learn the fate of their loved ones. Its horrible beyond imagination. Family members Still Holding on to hope their loved ones will be found. Two were on the phone with her mother while checking in for their flight at jfk. It sounded like they went underwater and then it went dead. Its been the worst days of my life. I just i guess i didnt know how much one person can love another until until you just dont know where they are at. Andre adam also at the airport, and he was with his wife danielle waiting for a flight to miami and danielle was found but he was not. This missing couple from tennessee were walking back from the security get after dropping off stephanies mother when the bombs went off, and on wednesday there was hope the couple had been found, and his brother was contacted by the state department and told they were on the injured list but then a call saying that information was incorrect. His brother tweeted out to keep praying they are found alive. We are going to speak to somebody whose loved ones is still missing, and they are hoping to get some word they are maybe injured but still alive. Our hearts go out to the families and we are hoping for good news. The political debate intensifying over how to respond to the pwrbrussels attacks. Hillary clinton looking to show evenhandedness and appear president ial apparently as a counter balance to the rhetoric coming from the gop attacking the republican president ial candidates for proposing things she said are dangerous in her view that would make a bad situation worse in the fight against international terrorism. She said senator ted cruzs proposal for patrolling and securing muslim neighborhoods were wrong and counter productive and dangerous and puts special emphasis on Donald Trumps assertion that u. S. Involvement in nato may need to be scaled back because its too expensive. Listen. Turning our back on our alliances or turning our alliance into a protection racket would send a dangerous message. If that mr. Trump gets his way, it will be like christmas in the kremlin. The former secretary of state calling nato one of the best investments the u. S. Ever made, and she gave a speech at stanford and part of it was directed to call on silicon valley. She said both sides had good points but apples position could make it harder to prevent attacks.

First there were terror attacks in paris and now terror attacks rocks brussels. Why has belgium become the epicenter of european extremism. Great to have you here with us in brussels. Lets talk about belgium. For many people it felt like a problem waiting to happen. We always heard belgium has more jihadis per capita than any other european country . We have to realize we are living in a time where theres a global jihadists insurgency. Belgium has a unique problem and the problem is that it has become the very epicenter, but its not new. In 2004 the madrid bombings were inspired from here, belgium and brussels. Its something very few people pick up on. What are they doing wrong here . Five key things. First, why belgium is important. The strategic location. Its central to europe and you can get to locations quickly and its easier to buy arms here than elsewhere in europe, and theres a lack of integration and it makes it easy for recruiters to recruit to a new identity. I want to stop you there. The lack of integration, we have been hearing about the ghettos in belgium, and immigrants come and not integrated and why havent authorities figures this out . Will this horror change anything about that . The first thing is, when migrants go to a new country they tend to gather together. Its not new to muslims or new to any of the migrants from any other country. We dont see this phenomenon among migrants that could be from india or china and we see them from muslim migrants living in ghettos and its not the lack of integration itself, but its creating the new identity in the vacuum created when people have not found something by which they can attach themselves to. When they feel aus trau sized they have no purpose and then they are susceptible to the leaders that want to do terrible things. What is the answer for belgium and europe . The answer is a short sense to keep the company safe and build resilience long term. Its primary prevention work so before people become radicalized. We heard from people who are immigrants and they feel identified with their country of origin. Does belgium need to do Something Different to reach out and make them feel welcome or is that possible . Are the two cultures we were never identified by our faith. All belgium muscles and european muslims want to be engaged with citizens, as equal citizens the same as everybody else. Thats the first thing the Belgium Authority needs to do, deal with them as belgium citizens. These guys that carried out these attacks were able to live in the ghettos for a number of days without actually anybody telling the authorities they were there. Thats tribalism and that needs to move away and its a twoway street, both the authorities and the citizens need to do more. What can the police do here . What will they change as a result of this week . The sad reality, this is not a new phenomenon. My worry and fear is they will look at the phenomenon through legislation. The first question is what can they do . The answer is very little. Putting troops to the streets of belgium wont fix of problem . Why doesnt that scare away extremists . You cant kill or ban an ideology. If we want to win the struggle long term, we have to tackle the ideology head on, and the political cause using the faith i believe in islam how do you break that ideology . The social, emotion and spiritual aspects of the narratives and conditions and provide alternatives. Thats the key. Muslims need to do more, and so does the Wider Community and treat it like we treat communism and fascism. The politics of terrorism. Ted cruz and donald trump have been talking about profiling muslims. Hillary clinton and barack obama taking them to task on that . Well discuss all that next. The intelligent, allnew audi a4 is here. Aint got time to make no apologies. Something well show you. Through small things. Big things. And spur of the moment things. Sheraton. I love to take pictures that engage people. And to connect us with the wonderment of nature. The detail on this surface book is amazing. With the tiger image, the saliva coming off and you got this turning. Thats why i need this kind of resolution and computing power. Being able to use a pen like this. On the screen directly with the image. It just gives me a different relationship to it. And i cant do that on my mac. This is brilliant for me. We believe in the power of active management. Management, by debating our research to find the best investments. By looking at global and local insights to benefit from different points of view. And by consistently breaking apart risk to focus on longterm value. We actively manage with expertise and conviction. So you can invest with more certainty. Mfs. Thats the power of active management. So now im not being perky, telling you that drivers that switch to progressive save an average of 548 whoo i mean, whoo. Donald trump and ted cruz facing a backlash for their controversial responses to the terror attacks. Barack obama and Hillary Clinton lashing out at cruz that muslim communities should be monitored by police. When republican candidates like ted cruz call for treating muslims like criminals and racially profiling predominantly muslim neighborhoods and its wrong and counter productive and dangerous. I just left a country that engaged in that kind of neighborhood surveillance, which, by the way, the father of senator cruz escaped for america, the land of the free. We are joined by cnn political commentator, peter pwaoeupber, and Time Magazine political reporter, mr. Miller. Donald trump for his part not ruling out using Nucle
