bombings ripped through the very heart of europe. we're just learning at this hour that belgian authorities are looking for at least three people who may be associated with the bombings. this is according to one u.s. official. and investigators believe there is a much wider network involved here. at this time, at least 30 people reported killed, 230 more injured. among them, at least 6 americans. the first attack was in a crowded passenger terminal at brussels international airport. people just checking in to get on their flight this morning. ten of them murdered in two explosions. a short time later a single powerful bomb detonated inside a subway train at a downtown metro station. at least 20 people killed there. and authorities releasing this airport surveillance video. the belgian federal prosecutor believes two men, on the left, may have been suicide bombers. you can see them there. investigators are now searching for the other man in the picture, the man in the white jacket. they believe he's on the run. the attacks were just six miles

apart. now the manhunt is focused on the nearby neighborhood of scarbay. police discovered a nail-packed bomb, chemicals and isis flag. president obama calling the belgian prime minister to express his condolences, and speaking from cuba where i am tonight, condemned the attacks. >> we must be together, regardless ofnationality, or orfaith, in fighting against this scourge of terrorism. we can and we will defeat those who threaten the safety and security of people all around the world. >> cnn has every single angle of this fast-moving story covered tonight "outfront." we begin with fred in brussels. fred, raids have been going on all night, as they are looking at more, worried about the possibility of more attacks. you're learning more about how they're getting tipped off to the location where the raid is behind you.

>> reporter: yeah, absolutely. i'm in the area where the raids have been taking place all throughout the afternoon hours brussels time, erin. it was quickly that the authorities moved into the area, because apparently they got a tip-off most probably from the taxi driver who may have taken these people to the airport. and apparently they took a taxi from the scarbeck area where i am right now. it's unclear whether or not it was the taxi driver who tipped them off. howeve theye here very quickly. we've beenere since the we've seen chopperhes in sky. wee seen one chopper in the what wehink was snipers out in open door, pointing their rifles at soing. again, what they found here in this area, again, very qckly was that nail bomb. they found chemicals. and they also found apparently an isis flag as well. what we've seen on the ground in the lasted hour or so, was a decontamination unit that went out of the area here. of course, if they didn't

identify the chemicals, that wouldn't beuch of rise. haven't heard so far is re, they foundn empty ce got apartment where they would have nail bomb and is fla as well. th latestre hearing from the people i goion. as of a couple of minutes ago, there was a lot of police vehicles goin andut o o this areath cor tdon i area rem in place, and ias for at least seven or eht hours at this point, erin. >> a right. ed, thank you very much. of course,s they raids go oney can to tck down t man that they are on thet for. and also, of course, the deep concern that they hav about the possibility of mores. mbin through debris a are theveillance tapes of bot of the sites, looking across the city, despately trying to find an kind of alue to piece together how this could h happened ading up to this morning's attack.

>> reporter: isis is claiming responsibility for a pair of deadly attacks in brussels today. this was the chaotic scene shortly after two explosions rocked the city's airport. two explosions in the international departure hall, just before 8:00 a.m. local time. investigators say it was the work of two suicide bombers. >> i heard an explosion. and then when we came out of the elevator, at that moment the second bomb exploded. then we saw doors flying, glass, ceiling coming down. >> the two explosions were quite close. they were almost like maybe 20 or 30 meters away from each other. time-wise, it was maybe three, maybe four seconds. by the time we realized what was happening on one side, the other explosd on the other side. >> reporter: one device exploded near a counter not protected by

security cpoints. dozens of dead and wounded lay scattered across the terminal's floor. hundreds of others ran for the exits. belgian police released this surveillance photo of three men pushing luggage carts. >> translator: at the airport we have a photo of three suspects. we can assume two of those three men committed the suicide attacks. the third man in a light-colored jacket and a hat is being searched for at this moment. >> reporter: a closer look at the two men on the left shows each wearing only one glove. investigators think it is possible that the gloves hid a detonator. even as the horror of the airport attack was unfolding, terrified screams of a child after a second even more deadly attack. about an hour later, about six ation.away, at a downtown metro >> as i w on my way to work this morning, i actually was reading the news and i heard about thesion at the airport. i was one metro back. and we felt a kind of small blast of air, and heard some

thudding in the distance. >> reporter: after the blast, belgian authorities scoured brussels streets, a desperate manhunt still under way for possible accomplices. belgium's prime minister addressed a shaken nation. >> translator: at this time of four cotry, more an ever time i call on everybody to show calm. but also solidarity. >> reporter: there is a very real fear of more attacks. in a statement, isis promised more attacks were coming. now, we have some more details of those suspects on that surveillance tape. they were apparently seen on the tape, and disembarking from a taxi together. they then moved through the airport. the man in the light jacket was later seep leaving the airport on his own. it appears to be possibly part of the planned attack, erin.

>> thank you very much, atika. just yards away from the twin explosions, a war zone truly today, joined now from skype from just outside brussels. i want to thank you very much for being willing to talk. i know this is a day you could never imagine experiencing. how are you doing? >> considering the circumstances, i'm- i'm okay. thank you.lieved even. >> you are alive. you are home. i know in so many ways, you must feel very lucky and very blessed. you were a hundred feet, not even a hundred feet away from one of these bombs. what exactly did you see and hear happen? >> 7:59, i hear the first bomb. which was a big blast. then i oriested myself towards it. eight, ten counts later, after

the realization, i hear the second -- you see and hear the second blast. then it's time for running. then we all west, we saw smoke and we ran towards the military because of being scared of potential bullets. and everyone just was in a big panic. >> what did you think was happening? did you think that this was a terror attack? what did you think was actually happening to you? >> well, the first thought only came after three, four seconds. but then you immediately realize it. and then -- but it takes another three seconds, andhe it's a second blast. and then you just know. it's time for everyone to run.

and everyone going on instinct and running towards the milit y military, as the first zone of safety. and then secondly, just towards the gates. >> inow that we' looking at like a war zone. i and that is what it was, right? with these bombs going off. there is a stroller there. there are people and families who were checking into the airport who were there to say good-bye to their loved ones on a trip. what did you see around you? with the other people and the people who suddenly saw their lives change so dramatically today, the injured and the dead? >> first, you just see smoke. then you see the ceiling coming down. and then you're just running, jumping over people.

towards an open area. after the second one, you hear screaming, and just a war zone, so to speak. >> we very much appreciate your taking the time to talk to us so late there after such a horrific and terrifying day. we are so glad you're okay. thank you. >> you're welcome. thank you. >> "outfront" now, former cia operative bob baer and kimberly dosher who was just at the brussels airport on monday. and chairman of the house select committee on intelligence. thanks very much to all of you. paul, what are you learning? we've got these massive raids. horrific attack happening at the check-in area of an airport in a city that was on high alert, that had been searching for isis cells for mont, wre one of the paris attrs w just apprehended days ago. what are you learning right now about the hunt, the manhunt for

one of these men? >> well, the manhunt carries on, erin. they want to find the people responsible, linked to them. they're warranted there can be follow-on attacks tomorrow. similar attacks could take place again in brussels. this is a large isis cell, they believe is responsible for all of this. the same cell that was responsible for the paris attack. the paris attack was planned, coordinated, staged from belgium, the plot gathered in several safe houses before those attacks. and belgian authorities in the months since have arrested more than ten people in connection with the paris attacks. but they haven't rounded up the whole cell. they got lucky last week, in getting salah abdeslam and killing a nigerian terror with a

role in the paris attacks. but the bomb maker being an individual called najim lau laachraoui, he was in the very same district of where they found the explosives just a few hours ago. >> so bob baer, let me show you this picture again. they have so little information. they have these three men, two of them they believe suicide bombers dressed in dark colors. and then you have the one man on the other side of the screen in white. let's talk about the men in black, though. they each have a glove on. they each have on one glove each. i know that's something you think could be very significant. why? >> well, they could be deadman switches. if you take your hand off the cart, the bomb goes off. even if the police suspected them and grabbed them, they

could still have detonated their weapons, or if they had been shot. these deadman switches are very common. you would have to know what you're doing to hook up the lek tricks. we'll have to wait for the forensic people to look at this. or they could have a plunger in the gloves so they could detonate them. i would imagine, with a minder there, the guy in the white, made sure they got in, that their bombs were hooked up right. remember, these guys are nervous, to say the least. or they're fatalistic or whatever you want to call it. to have a minder there to make sure everything's hooked up right is operationally sound. and what bothers me is these guys keep getting better and better and better, and they're moving from hard targets to soft targets. they can sort of hit at will, whether it's in response to salah abdeslam's terror plot or not, i don't know. these cells are widespread. belgians don't know what they have here, how widespread they

are and how many bombmakers they are. these bombs are pretty easy to make. i could teach you in a couple of days and take you out to a range and you could do quite well in making your own. this technology is very dangerous. >> mike, it's incredibly terrifying when you think about it happening at an airport check-in, not even security, something that makes everyone around the world afraid. you hear about this minder who they're now on the hunt for. they don't know where he is, if he's at large. you're talking about a city that has been raiding these neighborhoods for months and months, and all these raids going on. and a plan like this was being plotted and nobody had any idea. where do you think this man could be? this minder? do you think he is truly escaped the netted? >> you have to look at what happened after the paris bombings. remember, the logistics effort in this took about 30 people, they think. and maybe even more. and it also tracked back to this cell. all of these operations are likely to have been compartmentalized.

which is why i think operationally the police have had a difficult time getting into the operational cells. they were conducted in paris, they were able to break that down and find the folks at least participating in some way. there's probably another, or multiple operational cells that won'ted talk to each other in the conducting of their business. that's what they're worried about. how do you get at all of these operational cells that are likely separated. the thing that should concern them is with all t pocket litter, with all of the opportunity, meaning the information they take off the individuals they arrest, including in their apartments, where they stay, their cars, didn't get into the electronic communications of this other cell that operated that we just saw today. that's what's going to worry law enforcement moving forward, is what did they miss, and how are they missing these other operational cells. >> all right. all of you are going to be with me for the hour. we want to take a break here. after the break, the massacre coming days after the last paris

attacker was arrested. arrested alive. was it payback? were they worried he would talk and unveil this plot? plus, heavily armed security at airports and train stations across the united states. and donald trump weighing in on the attacks. >> radical islamic terrorism is a major problem, and we have a president that won't even mentioned term. soup and sandwich and clean and real and inside jokes and school night. good, clean food pairs well with anything. try the clean pairings menu. at panera. food as it should be.

breaking news tonight. two top u.s. officials telling cnn they believe today's deadly attacks in brussels are tied to the same network as the paris attack suspect salah abdeslam, who was captured last week after four months on the run. he was caught literally just a short distance away from the subway station where 20 people were massacred today. at the time belgian officials said abdeslam was ready for a new attack. deborah feyerick is out front. >> reporter: the capture of one of the most wanted men in europe was quickly and cautiously hailed as a victory by belgian and french authorities who warned a fight is not over. 26-year-old salah abdeslam, alive but wounded in the leg, following a shootout with belgian security forces friday. he was one of ten terrorists, including older brother brahim, allegedly responsible for the

november paris attacks which killed 130 people at four separate locations. authorities believe his capture and a warning that he was cooperating with police. may have accelerated today's attacks already in the works. >> his lawyer said that he was speaking to the police. either a direct message from salah abdeslam to his cohorts that they need to continue their planning for attacks immediately, or they need to, you know, seek cover. well, the message was very, very clear. he's talking, whatever you need to do, you need to do it quickly because you could be arrested soon as well. >> reporter: salah is believed to be driving around europe lasted year in rental cars. allegedly meeting with the paris attackers and other operate i was. the day of the attacks, they

believe he drove three of the terrorists to the soccer stadium. he then ditched his suicide vest in a trash can and fled. his brother, brahim, blew himself up outside a cafe. >> we still don't know. >> reporter: he spent the next four months eluding capture. there was speculation abdeslam may have traveled to syria. authorities were shobd when they raided a safe house in belgium last week and discovered his fingerprints in an apartment containing bomb-making term. abdeslam grew up in the neighborhood not far from where he was captured. >> the intelligence that belgian officials can get off him will be massive. >> reporter: his other brother muhammad still lives in the area and sat down with erin burnett after the paris attacks. do you still think, i love my brother? >> translator: these are my brothers. i love them. that's for sure. after all they've done, do i

admire what they've done? no. my family and i do not. >> reporter: there are two other potentially key suspects at large, erin. both of them linked to abdeslam. one is a childhood friend. it's believed they were together in paris several times before the attack there. the other man is somebody who they're looking for in that neighborhood today, erin. >> all right. thank you very much. i'm going to go straight back to my panel. and kim, i want to start with you. you hear deb's report and look at the timing here. do you think that this had something to do with salah abdeslam being captured four days ago? >> i have to say that in brussels over the weekend, u.s. officials at the con trens i was attending were all warned to be on high alert. one of them right during the operations to take abdeslam was actually hustled away by police from the venue because of the

suspected plot. they were later told that was a false alarm. on sunday, a senior belgian official told the audience that in questioning from abdeslam, they had learned that his network was much larger than they had expected. and that he had planned new violence and they said they were on alerted. that said, when i went to the airport on monday morning, there wasn't any additional security from the spot where the taxi dropped me off to the ticket counter, the same area where the explosion went off today. so, you know, there were security -- there was visible security throughout the city. but they simply can't be everywhere. >> they can't be everywhere. bob, you heard kim's reporting, about the no security at the airport. the groups are threatening more attacks tonight. that is something they have to take very seriously and must be incredibly afraid of. they obviously had no idea about this, despite all the surveillance they're conducting.

>> erin, that's exactly it. what these people have learned to do is stay off the internet, and not call back to syria, or get on the phone at all or using burner phones. they are using encryption, whatever they have. but even from the paris attacks, they haven't gleaned much from the metadata, the data mining. they're learning as they go, just as they're learning how to make better bombs, and communicate with each other and hide these cells. in addition, they're being protected by the local communities. as salah abdeslam was. if he knew about the attacks on the airport, let's wait to see on that. another thing they've learned is to compartment their information. they don't tell each other what they're about ready to do. and they don't need instructions from syria. all are data collection, it's been initiated in a big way. >> congressman rogers, i remember being in paris, and there were at the time reports and concerns that something like this could happen. some sort of an attack on an

airport. is this something that can be prevented? again, this happened in a city that is already on high alert and was expecting an attack. >> well, you know, guards, gates and guns is the old debate. the intelligence that we need needs to be both electronic and intelligence generated. that's how you're going to solve them. you have to disrupt them in the planning events. which is the concern about this particular event. because as all of that information collected, including phone numbers and other things, they weren't able to put enough together to disrupt this activity happening in a neighborhood right near where this person grew up. so the problem here is that technology is taking us one way, and we still keep talking about hiring more gates, guards and guns to protect everyone everywhere. as kim talked about, you can't hire enough people to be in every airport standing between the cab and where you check in your bags. that's not going to happen. so that's the challenge i think we have of law enforcement and

intelligence coming up. >> all right. all of you going to be with me, again, through the hour. the manhunt for the attackers on the run right now. seems the suspect in the whited coat left the airport in brussels today. across the united states, security stepped up. what is the threat of copycat attacks. hey sweetie, it's time. ♪ eye of the tiger tv anncr: good afternoon everyone. morning rituals are special. when you share what you love... ...with who you love. kellogg's frosted flakes. they're grrreat!

breaking news on the devastating terror attacks in brussels. at least 30 dead, more than 200 injured tonight. right now, a massive manhunt under way right now around the world and in belgium for anyone with links to the explosion. the authorities focused on a particular man. in this picture, you see two men dressed in black. they're believed to carry out suicide attacks at the brussels airport. but the man in the hat with the white jacket, he is still at large. officials tell cnn that they believe he left a bomb in the airport that did not explode. a raid of an apartment turned up a nail bomb, chemicals and isis flag. isis is claiming responsibility for the attacks tonight.

pam brown, why do authorities think that the man in the white coat left the airport? >> reporter: well, they've been looking at the surveillance video at the airport, erin, and it shows the man in the white explosion.g the two men after they belie this was all plheand, man in the white coat i left them.and then the big question is, where did he go? did he go t the metro station where as we know there was explosion an hour later, o did he go elsewhere? was that a separate group of people involved with that? those are still unanswered questions. we know that some names have been sred from belgian authorities, wit u authorities, with people they believe may have been involved with the atta but they haven'teen able to confirm the exact names, the identity of the three men we see in the picture. authorities believe there are at least three involved. but that there's a wider network, a wider network of

people involved with this attack, as well as other plots that were in the works. they believe that these plots were already sort of hatched before salah abdeslam who we know was involved with the paris attacks before hess aid rested friday, and they accelerated the attacks. >> pam, thank you very much. we're also learning in the united states, officials stepping up security across the country. at airports, at train stations, at landmarks. rene marsh outside reagan national airport. rene, what are you seeing? how much extra security are you seeing tonight? >> erin, police preparing to launch specialize d viper tees, everything from bomb-sniffing dogs to advanced screening technology. although the federal government is saying there is no credible threat at this point, the

overseaskslearly stoking increased concerns for the u.s. transportation system overall. we're also seeing at train stations, bus stations, a heightened accepts of police presence of the we're seeing bag checks, random bag checks at train stations. they're looking for explosives there. of course, the focus is soft targets. i'm standing at the entrance of an airport, that is considered a soft target. anywhere where many people gather but they don't have to go through a security checkpoint to access it. very difficult to protect soft targets. the attacks in brussels proves that point of just how difficult it is for law enforcement to guess and assess and make sure nothing like that happens here in the united states. but again, we're seeing a show of force to prevent that from happening. erin? >> rene, thank you very much. "outfront" now, tom marino, sitting on the homeland security and foreign affairs committees.

congressman, i appreciate you taking the time. you hear rene talking about the security of soft targets throughout the united states. are you worried about copycat attacks in the homeland? >> i'm worried about copycat attacks, i'm also worried about more terrorist attacks from razed.from anyone who's been and unfortunately, they don't have to follow a copy cat. they have enough terrorists lined up that i think are in the country that could attack us. what we need to do is absolutely secure the border right now. and if anyone does not pass an in-depth background check, they don't get into this country. we have to tell the embassies of the countries around the world, put a hold on people coming to the united states because we will stop them at the border. if they don't pass that information that we need to clear them, they don't get into the united states. even the director of the fbi

said we will have a system for this. >> congressman, i know you've had a chance to be briefed on the latest situation. is there anything you can tell us? >> well, i think as you know, i'm the vice president of the na it oh parliamentary asem pli, and this is another cle message weave to get to our european allies and to our nato members. i've beenfter them for several years now to suggest to them, please, secure your borders more so. because the individuals pouring into your -- and we have an agreement with 38 countries that allow people to come to this country on a waiver program, where they don't really need a visa. >> yeah congressman, you know the head of the defense intelligence agency just said last month, isis would probably conduct additional attacks in rope, but also attempted direct attacks on the u.s. homeland in 2016. do you think that will happen? >> there's no question, this

attack in brussels was, of course, a message to the europeans, saying that we can do this anywhere. but also it was a message to the united states, saying, we will get there and we will cause this destruction in the united states. that's why we have to just stop anyone from coming into this country at this point until they've been vetted fully. >> congressman marino, thank you very much. >> youe very welcome. at least six americans, six americans injured in the attacks that we know of so far. the state department says there are still a fair number of missing americans tonight. and donald trump speaking out in the wake of the terror attacks saying he would be fine with warboarding of suspected terrorists.

breaking news on the terror attacks in belgium tonight. the united states still trying to track down a fair number of missing americans. right now, we know at least po people were killed, 230 injured in the attacks. among the wounded at least six americans, including mormon missionaries from utah. >> every phone call you hope --

>> the call that might be from their son, mason. 19 years old, 20 months into serving his mormon mission in france and belgium, he is with his missionary partner, an an elder, at the brussels airport. >> the departure, one of the bombs went off there. that's where mason was injured. >> all of them were hurt. but expected to survive. the wells live outside salt lake city, haven't been able to speak to their son. they know he was close enough to the blast to be hurt. burns and foot injuries. >> having your sop in the middle of something like this. >> i think the word is, you feel helpless. you feel scared, because there's not a lot you can do. >> this isn't this family's first time in the center of a terror attack. 2013, mason and his father had just left this block at the boston marathon when the first explosion went off. moments later, chad wells

explaining what he saw to wolf blitzer. >> chad wells, are you on the phone right now? >> yes, wolf, i can hear you. >> how strange is this for your family to be involved in two of these? >> i think two is enough for a lifetime now. i'm just dumb founded to be honest. all i can hope is the boston experience gave mason some peace. i know he was in the turmoil, right there when the blast happened and it was pretty chaotic from what i heard. >> you're tracing his travels. >> wasn't expecting him to be in belgium. >> the terror attack didn't quell mason's desire to serve his churn internationally. the wells hope their son's mission on peace -- >> i hope it's a wakeup call to america and the world that we need to come together as humanity and not pull ourselves apart. >> as for finishing our

interview? >> okay. >> tell me about your head, honey. >> the call from mason. >> mason, i'm going to catch a flight over to paris. >> what was it like to finally hear his voice? >> it was amazing relief. pure joy to hear mason's voice, to know he's alive, he's okay. >> you heard chad wells there telling his son that he is going to travel to his bedside. as far as we know he's still planning on doing that, even though he is alone in europe. his parents want him to know that he is still in their thoughts. they hope to get to him very quickly. as far as the other two other utah residents, as far as we know, they were also wounded from very rap nell as well as burps. >> thank you very much. donald trump warning that today's attacks are, quote, just the beginning, those are his words, as he proposed his solution for stopping terror attacks in the united states.

in brussels tonight. isis claiming responsibility. the tragedy becoming a political talking point for the candidates. voters heading to the polls in three western states. moments ago republican front-runner donald trump doubling down on his plan to ban muslims from the united states. >> i'd immediately strengthen our borders as i've been talking about for a long time and i'd be very, very strong on visas, probably end a lot of them. this is a problem. radical islamic terrorism is a major problem. we have a president who won't mention the term, won't mention the words. we can be nice about it and we can be politically correct about it but we're being fools, okay, we're being absolute fuels. >> sara murray is outfront. donald trump has previously called for banning nonamerican muslims temporarily from entering the united states and today making that call again. >> reporter: that's right, erin. he's gotten a lot of criticism for this when he initially came

out after the shootings in san bernardino, he made this call, but what we've seen is that in a number of these states, particularly with republican primary voters, this is the kind of thing that has boosted him because in the wake of these terror attacks, there is fear, there is a sense of how do we keep people like this from coming back into countries where we should feel safe? countries like the united states, places like brussels. so i think that's the kind of thing that has actually helped him with republican primary voters even though many people thought it would hurt. i think we're starting to see some of the backlash from that coming from other candidates. we heard a little bit of that from hillary clinton today when she said we need to be reaching out to muslim communities, to islamic communities and make inroads there because the problem is when we seclude them, we have no idea what's going on there, then we have no idea how to root out radical islam and so i think we're starting to see sort of the pushback on both sides of the aisle on this, but it is the kind of thing, erin, that could help donald trump tonight in a place like arizona. >> all right, sara, thank you very much. i want to bring my panel back, congressman rogers, i want to

start with you. donald trump, you know, says it wasn't just doubling down on the ban, temporary ban on muslims, he actually doubled down on the ban on waterboarding. he says he thinks waterboarding should be used. he thinks perhaps if it had been used with the suspect in the paris attacks who was captured days ago, maybe he would have given information that could have stopped this attack. could he be right? >> well, it's hard to know. here's the thing. this debate has been had, and a vote was taken and so it got to the point where the president of the united states -- they call it enhanced interrogations. at one time, waterboarding was part of enhanced interrogations. that has been removed from the list. that has now been banned by law. i did hear him call for changing the law. for him to even do that, he'd have to come get a majority vote through both the senate and the house to change the law. currently the law would allow him not only to do it but couldn't give the order to do it as well. >> so, so i understand you're

saying the law can't be changed and the point of waterboarding, though, obviously, whether it would or would not have worked, is going to be something he's going to use on the political trail. ted cruz today, kim, also stepped out, said law enforcement needs to step up policing muslim neighborhoods in the united states. specifically targeting muslims. here's how he put it on cnn. >> if you have a neighborhood where there is a high level of gang activity, the way to prevent it is you increase the law enforcement presence there. europe's failed immigration laws have allowed a massive influx of radical islamic terrorists into europe and they are now in isolated neighborhoods where radicalism festers. it festers and grows and sadly that leads directly to the kind of attack we saw in brussels. >> what's your take on that, kim? i mean, specifically policing muslim neighborhoods. something that is being received well? >> well, there are a couple different ways to do that. hard power or soft power.

you can go in like they have done in molenbeek right now, you can see on the streets, i was there on saturday night, it looks like an armed military camp in some parts of that neighborhood and you can see the locals aren't taking to it very well. there's a real sense of confrontation. the other thing they could do is start doing more community policing, reach out to that neighborhood and knit it into the city's society. that hasn't happened yet. city officials say they'd like to, but right now they're trying to build these kind of relationships in crisis mode, and their intelligence services are overstretched. they were before this crisis. and right now they're trying to build this under fire. erin? >> and paul, when you have not just with ted cruz and donald trump said today, hillary clinton came out and said, look, we need more surveillance and need more surveillance of communications specifically. paul, thisoretically is happeni

nonstop in belgium, paris, small neighborhoods, yet it didn't stop these attacks. >> that's right, erin. one of the problems with communications these days is the terrorists can communicate without authorities having any idea at all. on the night of the paris attacks, just a few hours before the attacks, the bataclan attack team downloaded the telegram messaging app onto their smartphone. this is a messaging app which allows you to send messages with end-to-end encryption and also for those messages to self-destruct. it's not known whether they communicated with that or not, because they just weren't able to recover any messages so it's quite possible they did as part of the coordination for the paris attacks. this same cell, a network believed responsible for this brussels attack as well, so that's one of the very big challenges right now is that they're able to communicate much

more easier than they were just a few years ago. >> all right. thanks very much to all of you. more of our breaking news of the brussels terror attacks continues right after this. we'll be back "outfront." volkswagen believes safety is very important... so all eleven models come standard with an intelligent crash response system... hmm. ...seven stability-enhancing systems... hmmm... ...and equipment for two child seats. hmmm... for those who take safety seriously. like we do. the volkswagen safety in numbers event... is happening now! get a $1,250 volkswagen reward card and 0% apr on new 2016 passat models. that's why i run on quickbooks. details. i use the payments app to accept credit cards... ...and everything autosyncs. those sales prove my sustainable designs are better for the environment and my bottom line. that's how i own it.
