Isis is very good at this sort of thing, they know how to plan and they have resources. For the last year at least, isis has been organizing foreign fighters by language and nationality and sending them to attack their home countries. Among the targets, belgium and france of course, but also brian ross, abc news, new york. And here in the u. S. Especially, millions of commuters will notice increased security this morning as they travel the roads and rails. In new york city, thousands of additional officers are at the ready.

Gop frontrunner donald trump going much further than that telling abc news, he would water board surviving paris attacker Salah Abdeslam to get more information. I would use maximum interrogation technique. I would have waterboarding and a step further. Ted cruz is pushing for more surveillance here in the u. S. It is good Law Enforcement to focus on where threats are emanating from and anywhere where there is a locus of radicalization. Both bns and republican Governor John Kasich say that sends the wrong message. In our country, we dont want it on the create divisions where we say youre a muslim. Therefore, were going to keep an eye on you. We are fighting a terrorist organization. We are not fighting a religion. Reporter and you are likely terror talk in the coming days. Weise Hillary Clinton is going to be giving a counterterrorism speech later on today at stanford university.

We also know there was serious trouble in arizona when it came to voting. Long lines especially. Will there be an investigation into this . Reporter theres a investigation now underway. The Democratic Party is looking into this especially Maricopa County because some people were waiting in line for two to three hours in the sun and there were fewer polling places open odd up with more voter turnout this time around. Its a hot button election for a lot of people here. Whats interesting, when the polling places close, there were still hundreds of people in line. When youre in line you still get to go and vote. By the time they got up there to cast their ballots the projections were coming in before they could go vote. That was disconcerting to a lot quite a mess in some parts of arizona.

And joining us this morning, for some insight on this is former fbi special agent in charge of Counter Terrorism steven gomez good morning. How you doing . As you look and see all thats played out, what went wrong here . Well, you had some indicators that Law Enforcement should have taken a look at in belgium. He was a critical part of the november. And there was some chatter that was occurring about concerns in the community there in brussels where he was captured. And at that point, Law Enforcement should have taken the posture of banging the bushes as we call it, doing some additional surveillance, interviews, knocking on doors of people who were potential coconspirators of his and letting them know they were watching him. There was a lot of time there. Apparently as youre saying, somebody might have dropped the ball in not getting to this guy sooner. What can you tell us about this type of investigation 24 hours after the aftermath of the attacks. What theyre doing is looking at all the social media, communication devices or communications that could have suspects that were killed. And, of course, theyre going to try to find the one guy thats till on the run. Thats of highest priority trying to locate him. Theyre going to be doing a lot of forensic review of the evidence. Theyve got the one bomb that did not explode. Theyll look at that very, very hard and fast trying to figure out the fingerprint of the bombmaker of that bomb. Thats a key piece of evidence. Absolutely. Thats going to hopefully lead them to other people, lead them to the bombmaker which is critical. As we go forward, i mean, you covered counterterrorism for some two decades or so. Im assuming you still have a lot of connections with people in that field. Are they hearing anything about possible future attacks . East ser coming, passover is coming, as well. Right. Absolutely. Theyre preparing for that. Lease no intelligence thats indicating that theres going to be a followon attack say here in the u. S. Type of potential attack just because of the fact that these types of attacks especially if you look at San Bernardino, they happen out of nowhere. Theyre not on the radar. And they then have an individual or two or three that then commit the attack with no warning. So thats the problem. They have to be prepared for that. Absolutely. And critical days ahead. Former fbi special agent steve gomez joining us this morning. Steve, thank you. Thanks a lot. We always wonder how it will affect us back here home. A congressional report last year found about 250 americans have left to go abroad to engage in the fighting. Its just not clear exactly. People. The uncertainty of how you this could affect our subway systems and airports still remains. It is troubling. I was mentioning to steve during the interview, you have big easter pore christians and for the jews passover coming up. Even at this hour, there are many that are worried about what might be ahead. Yeah. Very true. Coming up, the world shows its support. The touching trib bus across the globe for the people of brussels. 1 World Trade Center there proudly displaying the red, white and blue overnight.

Since the bomb blast, take a look at this image, people in the belgian capital have been writing messages in a square outside the brussels stock exchange, a city very much on high alert. Were going to begin with Alex Marquardt in brussels. Reporter terror striking in the heart of europe. Belgiums main airport, a smokey war zone, the sti city paralyzed. The attackers hit at the height of rush hour. Those three men Police Believe around 8 00 a. M. , two blasts, suicide bombers in the departure hall outside the Security Check point.

In the dark tunnel, passengers climbed out of train cars, the terrified screams of a child. The path to safety down the dimly lit tracks. This man still clutching a bouquet of flowers. In other metro cars, people waited, confused. More panic set in. Some people started running. Some people started crying.

Belgian Authorities Say somewhere around 600 to 700 jihadis either in or out of syria or connected to an infrastructure here are active. Whether those are people that have come recently along with those refugees were not sure.

Reporter Homeland Security announced its security will be increased at tsa, but tsa is not responsible for the actual overall security at airports, only the checkpoints. Interestingly, the head of tsa was in brussels landing around the time of the bomb blast and david kerley, abc news. I wonder if one of the most secured airports in the world ben gurion in tel aviv have a check well before you get to the airport where youve got to stop your car. Sometimes they pull au side. If youre a single female in a cab, youre usually one of the first people they pull aside. Tourists obviously they want to ask you lots of questions. When you get into the airports, a separate screening. I cant help but wonder if youre going to see that at airports across america well before you get to the airport. It gives you a sense of how secure that airport in tel aviv. You can carry liquids above three ounces through to a plane. They have a different measure and lines of security to make sure that things are safe there. Its going to be interesting to see how it changes the dynamic here as u. S. Airports. The state department issuing a warning for many citizens who might be traveling not just in one country but all 28 that make up the eu.

There was a massive explosion. Stay down. Big bang. Everybody cried and came along here. We saw smoke, you know. What it was, a truck or was it a terrorist. The second i heard it, i mean i felt it. I can still feel it in my chest now, the first blast and debris and smoke. It was a nightmare. The Worst Nightmare you could imagine. We saw a lot of people really badly injured with a lot of blood and we know that it was even worse inside but we could not see anything because of the smoke. [ siren ] 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. You just feel like a wave. Explosion, you know, a wave goes we saw smashed windows and we didnt get any information. Hundreds of people started running. I ran with them. There was no clue as to what was going on. Everyone started screaming and people dropped to the floor. People were crying. 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. We just decided to go for it and get off the train and try and find safety. You there was really the sense of humanity that emerges in the sense of chaos to me shows these types of things dont defeat the human spirit. I think its that image of the train they say that the explosives were far more greater than that was used in the paris attacks. So troubling that image to see it completely obliterated.
