The others say his brother, khalid was killed and a massive hunt is under way for the third man seen at the airport. In a moment, well get to the report on the Military Hospital working to identify victims of the attack and well be speaking to others throughout the hour. But first, fred pleiken has been in the neighborhood a taxi driver led investigators to after he recognized the airport bombing suspects as passengers that he had picked up. Fred has more on what police found the. According to the authorities, an apartment in this building, in the district was used as the main bomb making factories both for the attacks on the Brussels Airport and the one on the metro, as well. The police say that they have recovered some 15 kilograms or almost 40 pounds of the explosive tapt as well as chemicals, screws, which, of course, are often used to mix into explosive device toes make them even more deadly and an isis flag inside one of the apartments in that building. Now, we were able to speak to someone who says that he lived on the same floor as the alleged attackers and he says he barely saw them around. Translator ive never seen them except one time i came across one that was skinny. I said hello and i greeted him, but he didnt respond and i never saw them again and i feel scared. The raid here lasted several hours. It involved a lot of Police Officers and Police Helicopters with what appear to be Police Snipers glancing through an open door of the helicopter he and repeatedly pointing their rifles. Afterwards, forensic teams worked pretty much the entire night. They recovered a lot of things from this apartment building, but they also recovered something in the garbage can outside, a laptop that appeared to contain Something Like the will of one of the attackers where he was apparently saying that he pelt the police was on to him and he felt if they did not come through with this plot quickly, that maybe they would wind up going to jail just like salah abdeslam. People fear those involved in the attack could still be at large and could still pose a threat to society here in belgium and here in europe. They also believe some of the things theyve recovered from this apartment complex could help them track down some of those people and bring them to justice. Cnn, brussels, belgium. Politicos senior ecorespondent heath joins me now. So many questions are being asked of the security services, of the government, across europe. They promised that they would try to prevent Something Like this after paris and we find out now the networks are all interlinked. Yes. So i think that some of that knowledge of the networks was understood. But what wasnt understood was exactly how willing these networks were prepared to act. Some of the things viewers dont necessarily understand is if youre trying to track a suspect, someone who you think is about to bomb somewhere or could have the capacity to do that, to keep on top of all forms of communication, even find forms of communication, you might need 15, 20, sometimes 25 sxertsz to keep on top of all that. We know about 540 belgiums went to syria to train to be radicals. They think about half of them have come back. If you think up to 250 people could be on that list, youre talking about hundreds and hundreds of highly trained agents that belgium doesnt have. They dont seem to have the intelligence they need, do they . And theyve been underfunding those services. Obviously, a lot of that planning happens through Digital Networks and digital means now. Obviously, its not the same as the u. S. Government. Its a smaller country. But think about that, that its clearly not the sort of that the u. S. , the uk, france or even other smaller countries around the world would be dedicating to these resources. So you have these smaller European Countries who have been trying to develop in the case of eastern European Countries or in the cases of countries like belg jump who have been coasting a bit is a fair assessment. Theyve been able to ride on the coat tails of other countries like u. S. But until these issues have hit home, they havent had to say, hang on, we need they happen these tenyear plans, we need to double or triple what were doing. Belg jump has said that now, but to make up for decades of underinvestment, you cant do that in three or four months. You cant rain 200 arabic speakers out of the sky. Thats where you need to draw in these other resources. But the belgians are struggling to mobilize all of that now. So the answer is to do what america did after 9 11 and get all the agencies to coordinate together. But europe is not the United States. There are separate jurisdictions and if youre from one security agencies, youre not going to open up your books from one from another country, are you . That is the starting premise. But what you have that other places dont have is the European Union. So the obvious focus point is to try to do this through the European Union. But weve seen in lots of other areas, i used to have some knowledge of cyber security, for example. Now we know in europe theres seven or eight countries that do that really well. And those seven or eight, mostly the big ones that your viewers would think of off the top of their head, they dont like shares information with the smaller countries. Theyre not going to hand over their critical information to bulgaria. Yet a country like belgium, they can be the weak link in the chain, someone who is packing into a Nuclear Power station, somebody who is going to infrastructure like the airport that we saw this week in brussels. So these bigger countries now have a fundamental choice to make. Pull the smaller ones up to speed, share more information or do all of that and use a conduit like the European Union to stop these tragedies in the future. Thank you so much, indeed. Stories have been pouring in, as well, about the victims of the brussels terror attacks. Leopold hesch died in the metro station explosion. He was a law student. Those who knew him described him as brilliant and kind. Olivier delespesse died, as well. He was on his morning commute to his job. Sasha and Alexander Pinczowski was waiting to board a flight to new york. Their mother was on the line with one of them when they dropped. Just imagine. Their families havent heard from them since. Atika schubert joins me from brussels. Shes been following the story of survivors. But also, all these people who are unidentified. Absolutely. Its very difficult to identify many of the victims. And a number of hospitals, including the royal Military Hospital that we visited yesterday is trying to help identity many of those killed. Unfortunately, because of the power of the blast, many of their bodies are so badly mutilated that the only way to identify them is either fingerprinting dna or dental records. So its a really tough shjob. In terms of how the hospitals are responding, i mean, there was a pretty incredible response, wasnt there, in the immediate aftermath of this terror incident. If theres one thing that did come out well from this, its how the response was hammed, actually. But theyre still responding, arent they, and theyre still struggling. They are still struggling, simply because, you know, you consider that hundreds were wounded, but more than a hundred still remain in hospital. Were talking about injuries like burns, which take a long time to treat. Shrapnel wounds that often require multiple surgeries. And its not just doctors pressed into this. We also met yesterday a Hotel Manager who actually turned his lobby into a triage center. The red cross basically came in and said we know youre helping people, but we need to help more and were able to bring people in from the metro station and decide who to save first, essentially. And it was incredible to see a hotel lobby completely transformed into this. So everybody really tried to help the best way they could. But its it was especially tough for medics and hospitals, as well. And in terms of those missing people, what sort of system shattered the belgium city of brussels. Hospitals are still coping with the influx of victims. Were standing outside the royalty Military Hospital here in brussels and this is where at least 80 of the victims from the airport blast were brought to suffering from multiple burns and shrapnel wounds. The entrance was transformed into an emergency ward designed to be used in war or natural disaster. Many now have been transferred to the specialized burns unit. Though the hospital is working with investigators to identify the debt. Yan vase was among the first medics at the airport. What was the first thing you saw when you got to the scene . Chaos. Dust, chaos, people shouting, crying, all people crossing help here, over here. Ive never seen it before. It was a war zone. For 20 years, he has served as a military medic in places like afghanistan, but he has never seen anything like this. A bomb that investigators believe was packed with nails and bolts. I saw a lot of people with holes in their body. The people were hit by pieces that flew around. I saw children with with wounds, penetrating wounds so it has to be some explosive device. Things are floating around with a great high power. Outside the hospital, soldiers stand guard. The belg jump flag flies at halfstaff. Do you also have a picture of your girl friend . 25yearold salamani is searching for his girlfriend. They have a 1yearold son. What kind of a person is she . Shes very shy. Shes short and shes strong. Shes a strong person. Shes a strong person, yes. Jonathan has set up a Facebook Page for information. He says she was studying to be a botanist and on her way to school when the bomb ripped through the train car. Her last iphone location was near the metro station. Are you worried that maybe shes been injured and may be unconscious . I dont think. I dont think. I dont i dont want to think about this. And hospitals across brussels, the heartbreaking search for answers continues. Just to show you how difficult this is, only three of the 31 that were killed have been identified and there are four wounded that have been been identified because theyre still in a coma. So it is a painful search for family members with, max. Atika, thank you so much. We continue to try to find who those unidentified are. Its a horrific situation for the families wait to go hear. British authorities, meanwhile, say they have foiled a terror plot in london. Police say two University Students in their early 20s were planning to kill soldiers, Police Officers and, as well. Next on cnn, a look at what the brussel attackers may have left behind before their deadly rampage. We have details on some surprising findings that were getting from our investigations. The and clean and real and looking good and sandwich and soup and a new personal best. And a little help and soup and sandwich and study group. Good, clean food pairs well with anything. Try the clean pairings menu. At panera. Food as it should be. When it happens in paris, when it happens elsewhere, you tell yours, it wont happen here. To see it happen 500 meters from here, its not good. As a citizen of brussels, it hurts to experience Something Like this. Trirchl is coming close in a scary way. Brussels is a beautiful city. We are not going to let our lives be dictated by terrorists. Youre watching cnn special coverage of the terrorist attack here in brussels. And police are searching for this man and possible acome hiss, as well. A federal Prosecutor Says he placed a bomb at the airport and left. Officials are concerned tuesdays attacks are part of a bigger plot. Theyve been collecting evidence and antiterror raids all over the city. Were getting more information as well on the explosives attackers used in brussels. In a police raid, officials found 15 kilograms or about 50 pounds of the explosive tatp exposedly belong to the bombers and in this case pa Nick Peyton Walsh has more on this. Children screaming. Is this the aftermath of a tapt bomb . Officials found 15 kilograms of the explosive where an alleged bombmaker was hiding out. Its a home made explosive with a sinister nickname, motor of satan. Its sensitive to heat, hole tile and can potentially cause extensive damage. Experts say its cheap with ingredients that are easy to come by. 90 of the stuff we have here, you dont need a license to buy. I can go in the truck right now about half an wore away and come home with probably 90 of this. Brussels is not the first time tatp has been traced to terrorist attacks. Last november, ibrahim dead nated it as part of the paris attacks. One component, tatp. July 2005, bombs explodes throughout london. 52 dead, more than 700 injured. Investigators discover the home made bombs contained tatp. September 2009, a man is arrested for plotting to bomb a new york city subway using tatp. He gets the greens he needs at a colorado beauty store, a lowes and a walmart. Youre not going to generally get these people based on what they purchase. He says tatp ingredients are so readily available, buying the items may not raise suspicions. Thats why intel is key. Majibul asazi was involved in boiling tapt in a hotel room in aurora, was not identified for the ingredients he was purchasing. He was identified because of good intelligence in monitoring email accounts where he came up. That was Nick Peyton Walsh reporting. I want to talk more about tatp. Lets bring in steve moore, a retirery supervisory agent with the fbi, as well. Steve is live for us in los angeles. How much have the Law Enforcement community been dealing with this type of explosive in recent times . Well, i dont think it was even seen until the 1980s the. And so were just playing catch up in learning what this stuff is, how easy it is to synthesize or how difficult it is and how difficult it is to move around. It actually is almost well, its very dangerous to even the terrorists, thank goodness. Why is it so attractive to isis . Its attractive to isis because you can get this stuff without you can get the precursors without having licenses, things like that. The problem they have is that the Hydrogen Peroxide that they need and the acetone, while they can get it, the Hydrogen Peroxide is not concentrated enough. So thats what the boiling was about that the reporter was talking about. The boiling is to condense the Hydrogen Peroxide to a more weaponble concentrations. So when you look at the aftermath of what happened here in brussels, do you think that was an effective bomb making t kit. Yeah. And this is the thing about tatp, if you dont know how to use it correctly, it will kill you on one end of the perspective or it wont go high order of the other end of the spec truck. If you heat it up, it will kill you. When you see somebody make tatp go off, of this high order, they knew what they were doing. They didnt pick this recipe up off the internet and say, ill try it. This person was tricked. And in terms of trying to cut off that knowledge or that supply of the various ingredients of this explosive, how do Law Enforcement deal with this . It doesnt necessarily raise alarm bells when you buy the raw ingredients. No. And thats the thing. You can go to any Hardware Store and pick up acetone by the gal ron. I happened to do that two weeks ago for a painting project. You can get Hydrogen Peroxide anytime you need it at any drugstore. The thing about this, however, is when you start synthesizing this material, you find massive odors, massive smells. What we have to start looking for is not the precursors, but signs the precursors are being manipulated to make the substance. Thank you so much, indeed. For now, were going to turn it back to my colleague, Errol Barnett who is at cnn central. Hello, everyone. Fascinate to go hear about the explosives connected to this attack and how readily available they are. We will get you back to brussels in a moment. But first, we want to bring you new details on another developing story at this hour. Australia says two pieces of plane cart bre are highly likely to be wreckage from missing Malaysian Airlines flight 370. Matt, this is yet another promising lead. There was that debris found on reunion island in madagascar. But its also another sad confirmation for relatives of vict victims. What exactly do we know . That the. The pieces of debris found here were found on mozambique last month. They were shipped for further analysis. That investigation has since been completed and we did hear from australian officials today saying they are highly sure of the fact that those two pieces of debris are from the plane. We also heard from the malaysian transport minister. He spoke to reporters not long ago. The lets listen to a few more details that he gave. Pieces of debris belong to boeing. Secondly from the paint and expense ill of these two pieces, it is similar to mass airlines and also that we concluded that it is most certain belong to so further confirmation to the families of those on board. This is yet another step in this investigation that has been going on for so long. We did reach out to some family members here in china about or for their reaction to this news. One person spoke to us, john whey. His mother was on board the plane. He told us that finding the plane debris does not equal to finding our loved ones. If they can find debris as far away as africa, the authorities should reassess their searching area and hypothesis. Hes not sure about this debris. But Authorities Say according to their models, its highly plausible that debris from this missing airline could have drifted that far in the ocean. But still some doubt among faems family members here in china. Just a difficult situation overall. And our hearts go out to all of them. Theyve waited just two years to get this far and
