>> reporter: and then an hour later another explosion at the maalbeek metro station. isis has claimed responsibility for the deadly terror attacks that left at least 31 dead and at least 250 injured. tonight, 15 local hospitals are treating the victims. this nail was recovered from a victim's body, possibly indicating a nail bomb was cuesed in cues ed used in these attacks. the terror started at 8:00 a.m. in the departures terminal of brussels airport. >> there have been explosions in the terminal hall. >> reporter: two bombs exploding just minutes apart. one near airline baggage counters and another by a starbucks counter. law enforcement later found a third bomb in a suitcase that never detonated, leading them to believe the first two bombs may also have been in suitcases. >> you just feel like a wave, a
we didn't get any information. >> reporter: the terminal filled with smoke and the sound of screams. travelers lying on top of each other on the floor. this man holding a little girl. >> stay down. stay down. >> reporter: people huddled in fear and then the questions. >> what it was, a truck or was it a terrorist? >> reporter: this man picked a small baby up off the floor before running to safety. the bombs so powerful ceilings collapsed. airport security scanning for victims. >> you have to go, sir. >> reporter: ordering people to evacuate, they rush out of the terminal. glass crunching under foot. >> hundreds of people started running. i ran with them. there was no clue as to what was going on. >> reporter: outside, smoke pouring out of shattered windows as terrified travelers run away. about an hour after the airport
seven miles away at maalbeek metro station. a bomb tearing through a five-car train packed with rush hour commuters. >> everyone started screaming and people dropped to the floor. people were crying. >> reporter: american brian carroll was on that train. >> collectively, we all manually forced open the door, and at that moment i looked at, you know, the platform and thought, probably it makes sense to get off. but at the same time if i get off the platform what's waiting for me on the other side? are there terrorists there that are going to shoot everyone as they get off? and we just decided to go for it and get off the train and try and find safety. >> reporter: one metro stop away from brian's, the terrified screams of a child. survivors helping each other out of the subway cars and walking into dark tunnels to escape. [ screaming ] this man still clutching a bouquet of flowers.
injured, including belgian professional basketball player sebastian belin. >> he had to stay on the floor for about an hour. so he lost a lot of blood until he was finally transported to a hospital. >> reporter: and then there's chad and kimberly wells's son, who was burned and hit by shrapnel but able to call his parents today from his hospital bed. >> but your eyes are okay? >> yeah. my right hand is also kind of badly burnt. >> okay. >> but it should be fine as well. >> words can't describe the joy and the relief that we felt to hear his voice and know that he was alive and okay and he's going to pull through this. >> how long will you be in the hospital? >> a couple weeks. >> oh. >> reporter: he's had a history of close calls. wells was a block away from the boston marathon bombing three years ago. and he was in france during the
now this. blast. therefore, he got burned by it. >> reporter: now investigators responsible. this photo shows three possible suspects from the airport attack. according to the belgian federal prosecutor, two of the three he says are likely suicide bombers. an urgent manhunt is now under way for one possible surviving suspect. the manhunt triggering raids across brussels. guns drawn, a drone overhead. police move in using a camera on a stick to peer into an upper-floor apartment. these people evacuated through a window. residents gathered to watch. "they did not allow me to go inside or even outside," this man said. "the people living there cannot go out." the sweep lasting deep into the night. the raids have targeted this neighborhood just a mile or so from downtown. this whole block has been cordoned off. and they have found yet another
nails, chemical products, and an isis flag. tonight, authorities are investigating whether today's carnage was triggered by this raid four days ago. the one that took down salah abdeslam, the missing attacker from the paris attacks last november. abdeslam allegedly rented the car that carried a group of terrorists to this soccer [ explosion ] abdeslam also rented the car that dropped off the isis gunmen at the bataclan theater where an american rock band was playing to a sold-out venue. four men brandishing assault rifles opened fire on the crowd. the most wanted man in europe all the while apparently hiding authorities. he evaded them for four months until they found him in this apartment only a few yards from his family home. abdeslam is believed to be the man in the hooded sweatshirt being dragged off a pavement by police, shot in the leg. you can see him limping as they force him into the car.
nearby buildings with their guns drawn looking for accomplices. authorities say in custody abdeslam cooperated, admitting to planning other attacks, all while hiding in molenbeek, a neighborhood known as a hotbed of extremism. the streets of this neighborhood are full of arabic restaurants and grocers and butchers, and it's one of the neighborhoods that has sent more jihadi fighters to syria and iraq than any other place in europe. three of the alleged paris attackers were from here and of the more than 500 belgians believed to have gone to fight for isis many have links to molenbeek. today brussels has declared three days of national mourning. and the world is rallying behind them. the french prime minister, manuel valls, saying "we are at war." and president obama reacting to the terrorist attacks from cuba this morning. >> we stand in solidarity with them in condemning outrageous attacks against innocent people. we will do whatever is necessary

smoking wreckage for clues, one chilling image, a grainy surveillance photo of three men dominating the international manhunt for one key suspect. and late details tonight on what may be triggering this latest onslaught of terror. here's abc's chief investigative correspondent brian ross. >> reporter: the key to the investigation tonight is this photo and the surveillance videos it came from. three men looking grim and determined as they push luggage carts through the brussels airport. now identified by belgian authorities as the suspected attack team. their names provided to u.s. officials late today by the belgians. >> the belgian authorities are going to be going through every one of those videocameras and seeing where these people are throughout the airport. was there maybe somebody else in fact who who was with them and broke off. >> reporter: two dressed in black with no effort to hide their faces are believed to have been the suicide bombers. their bombs hid nen their large bags according to officials. each wearing a black glove on
the bomb's trigger, according to one former fbi official. >> whether it's wires, strings, a button. something is there that when they move their hand it actually makes the bomb go off. >> reporter: the third man who authorities say got away and is being sought tonight has a hat pulled down over his face. pushing what may have been the third bomb that authorities say did not detonate. >> the other individual could be their handler. he wants to be able to live for another day, for another terrorist attack. >> reporter: bomb experts tonight are studying the aftermath of the devices set off at the airport. but already they say another one at a metro stop in brussels appeared to be much more powerful than the explosives used in paris last november. this x-ray of one of the victims shows how the bombers used three-inch metal bolts as shrapnel, tearing into human
>> no other reason but to kill and maim. hopefully the blast wave would knock them unconscious because it's devastating. >> reporter: and authorities believe it all represents careful planning and stealth operations by the isis central command in syria. over the last year hoping to establish sleeper cells across europe and the u.s. >> we know that isis created an external attack division last year that they created within that division units for each country. people who were from germany. people who were from england. people who were from the united states. >> reporter: and of course from france and belgium. >> unfortunately, there are probably more cells in belgium. maybe cells that were kept separate intentionally from this unit. cells that the first cell did not even know about may still be out there. >> reporter: and belgian authorities fear that the capture last friday in brussels
the paris attacks salah abdeslam may have triggered tuesday's attacks. >> as soon as members of the cell knew that abdeslam had been captured, they knew he would be going under interrogation. they knew the papers and the computers with him were being analyzed. that probably told them immediately go to ground, hide, get ready to do an attack. >> reporter: members of congress say they were told much the same thing about abdeslam's arrest at a classified briefing late tuesday. >> and in fact that arrest still may have saved lives because it may have been even more lethal if they had the luxury of more time to plot and plan. but i wouldn't be a bit surprised if the timing was connected to that arrest. >> reporter: security in the u.s. at major airports and transit centers was stepped up today amid fears the attacks in brussels could trigger attacks in the u.s. >> this is something he with think about every minute of every day. >> reporter: it certainly triggered some terror jitters,
>> keep your eyes open, watching what's going around. we've seen a lot more police presence. >> always aware of my surroundings. look left and right, up and down. >> we hope that, you know, the powers that be are doing what they need to do. >> reporter: officials were taking no chances. a flight that took off from brussels just before the attack landed in orlando, where it was met by a heavy police presence far from the terminal. it was cleared after an inspection of the baggage. and in denver part of the airport terminal was evacuated after a bomb-sniffing dog alerted on some baggage. it too was later cleared. but there are legitimate concerns given what happened in brussels. >> this is a completely unsecured area. always has been, right? >> completely unsecured. >> reporter: former homeland security official john cohen told abc's david kerley that the areas before airport security are especially vulnerable. >> we've built up checkpoints and screening procedures and screening technologies. but the front of the airport is vulnerable. someone can walk in the door
firearm and can create a lot of havoc and a lot of injuries with people who are waiting to go into the other part of the airport. >> reporter: at present u.s. officials say they know of no so-called isis cells in the u.s. but the fbi continues surveillance on dozens of americans in all 50 states who have shown alleged sympathies for isis. in the past 2 1/2 years, 103 americans have been charged with trying to join isis or are suspected of supporting the group in some other way. but still, it's far less of a problem than exists in many european countries. >> the number still is relatively small. and the reality is that the in the united states are not as isolated, not as alienated as what we've seen in certain places in europe like this neighborhood in brussels which was very difficult for the police to penetrate. >> reporter: for "nightline" brian ross, abc news, new york. and up next, join us on a

together in a somber similarity. on social media the hashtags jesuisbruxelles and pray for belgium shared all over the world. >> there was a massive explosion. the lights went out. the power went out on the train. everyone fell to the ground. it was clear to me at least that this was a terrorist attack. >> reporter: millions heard the voices of those who lived through the harrowing hours. >> i felt it. i can still feel it in my chest now. the first blast. >> reporter: recounting the horrific moments when survival was uncertain. >> it was a nightmare. the worst nightmare you could imagine. >> reporter: but perhaps more importantly, the true nature of humanity that can shine bright in the darkest times. >> it was really this sense of humanity that emerged in this sense of chaos. that to me shows that these types of things don't defeat the human spirit. >> for the latest on brussels, tune in to gma tomorrow. and as always, we're online at abcnews.com and on our
