Mistake before the attack. Thats all ahead in this hour of Shepard Smith reporting. Im bill hemmer in for Shepard Smith today. Massive police raids now under way in brussels. A desperate manhunt to find a terrorist whos believed to be still on the run. Here is what we know now just after 8 00 at night belgium time. The Islamic State claims it is behind the series of bombings that rocked brussels this morning. 30 people dead, nearly 200 injured. Were told nine americans are among the wounded, including a member of the u. S. Military. Some of them said to have critical injuries. Belgian authorities released this surveillance picture from the airport in brussels. Prosecutors saying theyre still hunting for the man on the far right. The other two apparently blew themselves up. The first bomb exploding in the checkin area of the brussels airport. Many witnesses say they did not know what it was. Some say they just heard a thud. Then a massive explosion blew out the windows, ripped through walls, and caved in the ceiling above. Cameras caught the confusion seconds after the first blast. [ screaming ] that couple you see not running away, likely fearing another bomb. One airport worker says he jumped into a luggage chute to escape. Victims covered in blood and soot, clothes torn apart, even their hair torched. A belgian tv station reports at least one of the bombs filled with nails, deadly projectiles that ripped into victims like a hail of bullets. Survivors who could run stampeded to safety outside. Lots of people with blood. I just run out of the airport. Everybody was running, running, running. We heard evacuate, evacuate. You can notice even in that confusion and panic, people still hauled away their luggage as they scrambled for safety. This while Emergency Responders raced to the airport and tended to the wounded. Terrorists in the heart of brussels were getting ready for another attack. Just about an hour after the bombings at the airport, another blast, this one at a subway station near the headquarters of the eu, the european union. [ sirens ] witnesses there saying the bomb was in a crowded subway car. The force of that explosion tearing through the metal, leaving the seats charred and twisted. That scene so gruesome, we have parts of this picture blurred. Those who survived describe the confusion as everything went dark underground. They file the out into the tunnel in an eerie calm with only the cries of a baby in the background. The severity of the attacks would not be clear until they came aboveground and into the light of the morning hour. One haunting picture came from this chaos. A few survivors hugging each other, a bloody victim help elseless on the ground only a few feet away. Terror in belgium and the urgent manhunt at this hour is our fox top story. We begin with greg live at the airport in brussels. Greg, these raids are under way right now. Reporter absolutely, bill. The airport behind us is quiet, deadly quiet. Terror has shut the place down with two explosions that rattled through the departure hall there. We havent seen any flights going in and out. It is closed, as is the metro station about three miles from where were standing, where terrorists also hit. Investigators are going through the rubble here at this airport and at this subway to try to come up with more information about this deadly, deadly attack by terrorists believed to be the isis organization. And yes, theyre looking at that picture, surveillance video, a surveillance snapshot in the airport showing a man in white clothing. He is believed to be a key suspect. Was he the string puller . Was he the organizer . What was his role . We dont know. What we do know, though s that there were two men beside him, two men in black. We believe that they were suicide bombers, and at least one was killed. The search goes on through the brussels, door to door, searching apartment, searching the places where the terrorists have hid, where suspects could be hiding. We understand, we just learned this in the past hour, in one apartment another bomb, as you describe, with nails inside and an isis flag found. No suspects there, but the implements of terror were found. The search continues, bill. Greg, there was a significant arrest just four days ago. What more do we know about the role that arrest may have played in todays carnage, if at all . Reporter this is a very interesting question, bill. The Prime Minister of belgium just an hour ago says he still was not able to make a connection between that arrest and this terror, but you got to believe that there was a connection. Four days ago, the prime suspect, remaining suspect in the paris terror attacks arrested. He told prosecutors over the weekend that he was planning another attack on brussels, that he had created another network. What were these attacks all about . Were they simply revenge attacks for the arrest, or as others are speculating, were the terrorists going out and committing the attacks that had been planned before abdeslam revealed the attack . Thats the big question. One of many police are looking at right now as they try to sort out yet another scene of terror and carnage right in the heart of europe. Back to you, bill. Thank you, greg. Good work. The feds here at home say there is no evidence of any specific threat to the u. S. , but they are keeping an eye out for the possibility of a copycat. Team fox coverage continues now. Our chief intelligence correspondent is live in d. C. Youve been working your sources all day. What are you finding in terms of where the focus for investigators is right now, katherine . Thank you, bill. Sources tell fox news the highest priority is identifying the suicide bombers, likely through dna to determine when the men have ties inside the United States by running their names against watch lists for known terrorism suspects. A former Senior Intelligence official said the weaponry, including suicide belts and multiple locations, could not be done on the fly. These parts look fairly sophisticated. These are not the kind of things that are cooked up over the weekend. Just based upon how they were done. The weaponry that was used, the fact that it was multiple locations and happened sequentially tells me a lot of work had gone into this. Counterterrorism sources say the plot was in the pipeline in fridays arrest as the paris suspect, Salah Abdeslam, ax accelerated the timeline. Officials have been receiving regular intelligence updates. At the same time, security has been increased at airports with armed police at Dulles International in suburban washington, as well as bombsniffing dogs. Similar steps are being taken in large subway stations across the country. We were on the air three hours ago together. The security footage released since then. It has given investigators clues of the suspects. Well put it on screen, and you to look at. As soon as this picture was released by the belgian authority, fox news was told by two former senior fbi agents as well as a former Intelligence Officer to draw our attention to the suspects there on the left in the tan and the black who wore that single black glove holding the luggage cart. It was described to us as evidence of a possible detonator, whats known as a dead man switch. One scenario is once the pressure on the handle is broken, for example if the suspect was shot dead, the bomb would still be trigger. Ed. These switches are used in the event a suicide bomber is taken out so the vest or belt will still explode because that contact is broken. Lets take a closer look at the guy on the right. The video is not great. He does appear to be wearing a kind of disguise. The coloring between his face and nose appear too uneven. Then theres the hat and what appears to be glasses as well. A former military Intelligence Officer said in this particular case, its entirely feasible that the guy in the white was acting like an escort. That is pretty common with female suicide bombers. We dont seem to be dealing with women in this case. But the point of an escort is to keep the two individuals, the two bombers on track mentally so that nothing interferes with the detonation of those devices. Most typically, to take them to a target that has already been surveilled by the escort. So this individual played a very Important Role just based on the photo and the disguise and the fact that the two guys i dont know if we can see that picture again. There on the left in the black and tan, khakis are the uniform of americans. They are not the uniform of europeans. This to me says very clearly that they were trying to present themselves as much as possible as western nationals traveling overseas. Fascinating stuff. Katherine, thank you. When you get more, bring it back. I want top bring in a former cia terror analyst. That last point katherine was talking about, its almost like they have a spotter on site. Abdelslam seemed to be that man in paris when he either chickened out, or he was never designed to die in the first place. Whats your view on that . Well, absolutely. Right now from the video, there are some things we know, some things we dont know. You might have had somebody involved with the attack who scoped out the scene before hand. You might have had individuals who were responsible for carrying out the suicide bombing themselves as evidence has shown it is believed thats what occurred here. You might have also had somebody not at the scene, not on the videotape coordinating logistics from some other location. Thats what officials are worried about right now, trying to put these pieces together. This also comes on the heels of the raid and capture of a very wellknown terrorist himself, and that undoubtedly had to do with the timing of this attack. They may have been very worried that intelligence officials were on their trail, and they may have been forced to carry this out sooner than they had planned. Tara, one thing we know, theyre adapting. Theyre learning quickly. And they know the terrain. Theyre using disposable phones. Theyve got these places scoped out. They are staying ahead of Law Enforcement, and that is obvious after today. I agree. I mean, terrorist groups are notorious for evolving, for taking tactics from previous attacks and applying them to new attacks. What we see now is their ability to exploit and use new technologies. Whether thats social media for recruitment purposes, whether thats social media for propaganda value and to get Media Attention on their attacks, or whether thats encrypted communication applications on their phones and devices, which may or may not have helped them to evade Law Enforcement. Its too early to say. I dont want to jump to any conclusions. Thats a very, very important point. We have been focused on encryption in this country for the past year, right. Now we know theyve been using disposable phones that perhaps were used one time. That is a very difficult thing to stay ahead of. Exactly. And its really important to note a lot of people say now 20 20 hindsight. U. S. Officials were aware there was a high threat level. Individuals have been saying belgian targets might be at risk. There are a lot of soft targets. Airports, transportation hubs. These are known to be terrorist targets. But thats overarching strategic intelligence. What Law Enforcement need is the tactical, nittygritty, in the weeds intelligence. The reports, the phone calls, the emails that are going to show when and where and who. Without that type of intelligence, the signals intelligence, the communications between the individuals, you can have all the general threat assessments you want, but thats not going to help you thwart a specific attack at a specific location at a specific time. And we are behind on that point. Tara, thank you. Tara miller there in washington, d. C. Great analysis there. Thank you. You bet. Continuing coverage after the brussels attack, including the effort to track down anymore suspects. Are they out there . And if so, where . Well talk to a reporter on the ground. Constipated . Trust number one doctor recommended dulcolax use dulcolax tablets for gentle overnight relief suppositories for relief in minutes and stool softeners for comfortable relief of hard stools. Dulcolax, designed for dependable relief [engines revving] you cant have a hero, if you dont have a villain. The world needs villains [tires screeching] and villains need cars. We are now seeing some of the americans wounded in todays attack in belgium. These men are missionaries with the mormon church. Were told they were near one of the bombs that ripped through the brussels airport. They were on a mission in paris. A former Oakland University basketball player out of brazil was among the injured as well. His dad telling cbs news he was bleeding on the airport floor for an hour and that hed lost a lot of blood. We do not know the name of the u. S. Military member wounded in the attacks along with five family members. Pentagon sources indicate some of them are in critical condition. I want to bring in jake simons, who is outside of the apartment of one of the terrorists now. Jake, what do you have for us there . Well, a little bit of speculation surrounds the role of Salah Abdeslam. He was the alleged mastermind of the paris bombings. He was arrested just a few days ago just a few hundred meters from where i am right now. Now, theres a lot of speculation about him because it seems as if the attacks today are in some way linked to his arrest. Initially, earlier in the day, people thought that perhaps the people who carried out these attacks were worried that once salah was being questioned by police, he might give away the details of their attack. They also thought that maybe this attack was a revenge on his arrest, but the latest news given from an anonymous source within the Belgium Police is they think Salah Abdeslam was going to be involved in the current attack today and that he would have actually been playing a key role in the attacks if he hadnt been arrested a few days ago. That official has been saying that Salah Abdeslam has been forming a new network in brussels around him following the paris attacks, and he was intending to carry out this attack today as well. Jake, they were living in plain sight in that neighborhood. Perhaps some of them never even left the neighborhood. How is that possible when you know theres been a manhunt throughout the continent, and especially concentrated in that very area for the past four months plus . Well, its absolutely astonishing. Right outside where im parked now is the apartment where Salah Abdeslam lived. His brother was in there today. I had a very quick conversation with him. A few doors down is the house of where another terrorist accomplice who drove allegedly drove Salah Abdeslam to paris to carry out the attacks lives. Hes now on the run. Then just a few couple hundred meters down the road is where Salah Abdeslam was hiding out and was arrested. Its absolutely astonishing that, you know, within less than a square mile all of these sort of landmarks of terror exist in such close proximity. When i spoke to Salah Abdeslams brother earlier today, he said, and i quote, i cant tell you if he was involved because if i told you i knew, id be in very big trouble right now. So theres a sense that, you know, all of this was happening right here in close proximity and nobody is talking. Thats his brother . And the brother has not been questioned . The brother was questioned in connection with the paris attacks and was then released. Hes been making a big show of the fact that he had nothing to do with the attacks. He condemned the attacks and came across quite well in the media. We did learn a few months back that he had a bit of a shaky past. He was found to be robbing corpses when working for the ambulance service. So he isnt as squeaky clean as he appeared. Thank you, jake simons. You wonder in that country thats been on edge for more than four months when they realized yet again that they are living among them. In a moment, remember investigators last week caught that terror suspect linked to the paris attacks in paris. The judge argues they made a big mistake by revealing that suspect Salah Abdeslam has been talking. Hell make his case next. Growing up, we were german. We danced in a german dance group. I wore lederhosen. When i first got on ancestry i was really surprised that i wasnt finding all of these germans in my tree. I decided to have my dna tested through ancestry dna. The big surprise was were not german at all. 52 of my dna comes from scotland and ireland. So, i traded in my lederhosen for a kilt. Ancestry has many paths to discovering your story.

[ beeping, whirring ] great caesar salad and now the name your price tool shows people policy options to help fit their budget. Is that a true story . Yeah people really do save an average of over 500 when they switch. I mean about you inventing it. I invented the story, and isnt that what really matters . So. What else about me . So the top terror suspect in novembers deadly paris attack told investigators he was planning more attacks. Thats according to the foreign minister in belgium. Authorities friday captured Salah Abdeslam during a raid in brussels. The foreign minister saying he claimed he was ready to, quote, restart something. Meanwhile, his lawyer says the french prosecutor violated the confidentiality of the investigation by telling the public too much about the case. My next guest argues the information investigators released may have played a role in what we saw today. Fox news senior judicial analyst judge anna north ameriapolitano explain. It is all reading between the lines. It is highly unusual for investigators to be revealing what theyre hearing in realtime to the press and public. This guy is being interrogated. Salah abdeslam is being interrogated in belgium by belgian prosecutors, belgian ma jes traits. You have four different teams interrogating. Some of them are speaking to the press. They are giving the press such detail about what theyre learning in realtime as theyre learning it. All of this is getting out to his confederate, who obviously perpetrated today. Who knows if
