The belgian public tv broadcaster so fairly reliable source that there are that would be four different locations. Can you give us a sense of where these locations are throughout the city. Give us a sense of the geography. Reporter brussels is not large. Certainly a lot more concentrated than the paris attacks in november which from spread out. All relatively close together, the main airport for the city is just ten miles outside. None far away from each other. The importance youre striking one of the highest security area s then at least two metro stayings that have symbolic locations next to the seat of the belgian government and seat of the European Union. These are all not yet confirmed. Tuning in at the bottom. Hour youre looking at some scenes right now, the aftermath of the departure terminal we believe at the Brussels Airport. New video in to us. You can see what impact this blast had, i believe those are like Ceiling Tiles that have come down onto the ground. There are injuries reported there but now the breaking news that were getting right now our Alex Marquardt is there at the airport in brussels but saying that there are local reports saying there may have been an additional three explosions at metro stations all around this capital. Three different subway stations is the report that alex was getting from the local broadcaster essentially public broadcaster similar to the bbc of bruls. The significance of that youre saying is one of those is located near the eu. One is in the maalbeek area. The third do you think is near the nato headquarters . Reporter its what you were talking about. City is is that this city is home to these major institutions, the European Union, nato and, of course, all of these embassies relatively concentrated in the center of brussels and if these explosions did take place at these metro stations they are highly symbolic symbolic. One is next to the belgian government. Another is next to the Main Building housing the European Union and when you add on the explosions we know about at the airport two at 8 00 this morning. This would indicate a coordinated attack so hope to be getting more information from the belgian authorities at the top of the hour. There is a lot of confusion. At least one person killed but reports of more as the authorities have sealed off the airport, flights have stopped are on our way by foot to that departure hall right now. You mentioned two explosions happened around 8 a. M. Local time and then subsequently we have these reports, unconfirmed of three explosions at three other subway stations or three subway stations in the area, give us a sense of whats going on this time of day in brussels. Is this a peek time to be moving and getting to work. A sense of what the city is doing right now. Yeah, this is 9 30 in the morning right now and so and the explosions the first ones at the airport happened at 8 00 so you really cant get more peak than that. This is when people are taking the first flights out of the city during the day. This is when people are using the metro to go to work. This s is the highest traffic that the city will see. Targeted attacks, then, you know, this is the hour that makes the most sense to target. Now im seeing official word from the brussels metro, the brussels subway system they are shutting down the whole system. All metro stations are closing across brussels. That follows reports of three explosions at three different metro stations in the heart of the capital. Very symbolic areas next to the seat of the European Union and of the belgian government. A big deal, everybody. Were getting these reports of additional explosions. Local media reporting them at several metro stations within the city of brussels this coming after those two explosions that took place at the airport roughly about 8 00, id say, local time there in brussels. Brussels is five hours ahead of us right now because of Daylight Saving time normally it would be six. So, alex at this point theyve they have shut down the metro station. I could just imagine this is a city that is just in the throes of a lot of angst right now. Reporter well, absolutely. Imagine in the u. S. In d. C. Or philadelphia or new york shutting down the main airport and shutting down the subway station. That would absolutely wreak havoc. I remember about six years ago covering a double suicide bombing in the metro in moscow and the russians only shut down about six stops on the in et tree because they wanted to isolate it and keep everything going. Now, europeans are taking a lot more would take a lot more and were seeing it now. The belgians shutting down the entire subway system, a clear indication and confirmation of those three attacks that happened at the three different stations and so right now, the only way to get around this city heard yet whats happening with the Railway System but when you are shutting down the subway system of a major european city, that means there are strong fears of attacks and possible more attacks to come. Reporting in brussels with the recent events have you seen anything like this where at any kind of closures like this have occurred or where that would seem to be something that would occur. Reporter im sorry. I was asking in the recent events youve been covering surrounding all these events how unusual is it . Maelbeek . But these quick reactions. Not unprecedented but how its extremely unusual. To shut gown the entire airport and not couch it in language that would leave any short of room for any other possibility is a clear indication that they believe that this is terrorism. They there have been evacuations of other airports in other european cities like geneva and i was there but they were doused by saying this happens all the time. If youre shutting down the subway system, theres fears of more happening. It should be of note. Youre familiar with belgium as am i a lot of people travel through the rail system. Its a great rail network and all also more importantly it connects to paris and amsterdam and to the netherlands and within just a matter of a couple of hours with the highspeed trains there so theyve really a lot of people would be and would cripple the city. Reporter absolutely. A good point. Everything is close together and suddenly you drive an hour an youre speaking a different language. American students are always coming over here and getting their eurorail passes and traveling all over the continent. Something people have been doing for years so to a large extent people rely a lot and certainly rely a lot more on trains and than the u. S. Does. There are, of course, Budget Airlines that fly all over europe that are very popular, but this is these cities are so interconnected and that was one of the problems that we saw in paris, these people were able to slip into paris from other countries unnoticed. Under the agreement they have, there are essentially no borders between these european countries, there are checkpoints and sometimes people are stopped but it is very easy to travel and, alex, just give us a sense of where you are now, what youre seeing, what the scene is there. Reporter that was just a convoy. Were on foot. All the roads are empty. The police have set up a no vehicles are being allowed in. But people are being allowed to come and go on foot. We have seen some travelers, some of the thousands who were presumably trying to get out of Brussels Airport this morning leaving the airport trying to get back out to the highways and i would imagine get a car to go back into brussels. But we are approaching the airport. It is the scene of confusion, theres police tape, lots of sirens and Emergency Services all around the airport and i would imagine the same scene is playing out now in brussels with the closure of that metro system. Shut down the entire system and not just the stations that were reported to have been targeted and so right now theres going to be paralysis in the belgian capital. Lots of traffic, nothing moving in the metro and a lot of confused and scared people. Alex, i should mention were getting word from American Airlines, you mentioned one might have taken place in a terminal where American Airlines operates out of so the word is right now we are aware of an incident at the Brussels Airport departure hall and taking care of our customers, employees and contractors. At this time all of our employees and contractors are accounted for with no injuries reported. American Airlines Flight 751 has been canceled for today. When operations at the airport resume we will recommend reaccommodate, rather, our customers so American Airlines there addressle flight 751 and many of its passengers and crew the airport this morning. Brussels airport did tweet that passengers that are still located in other areas of the airport are asked to remain calm and to wait for further information. Alex, you mentioned youre seeing many so of these passengers stream out. Is it large crowds of passengersy do you get a sense that theres still theyre still at the airport because those are the pictures we have earlier of large crowds, just kind of floating around trying to figure out where to go or whats going on. Some of them emotional talking to authorities. And really it just seems like everybody is still there. What is your sense . Well, initially it was a trickle but thats because we were further away. Now were closer coming up on what looks like the main perimeter around the airport. A lot more people, a lot more of a Police Presence and more passengers. Im looking at a man now clearly wounded, wrapped in a blanket. It is bloody and so he would be one f of the many wounded at the airport this morning. The scenes were seeing are not chaotic of theyre relatively orderly. People streaming out with their suitcases away from the airport. Confused. Not knowing where to go and see people getting on to buses who will be taken away from the airport. They were trying to fly at 8 00, 9 00, 10 00 in the morning when most of the early flights of the day are taking off talking about thousands trying to leave this airport who had packed into that departures hall and who are now not able to fly. Many wounded and so we are seeing a steady stream, really a river of passengers with their bags leaving the airport trying to figure out where to go. Our Alex Marquardt is at the airport in brussels where several have been injured and at least one person is dead but were also getting this report an ap reporter saying several people injured in explosion in brussels metro near the eu offices. The explosions at the metro took place at three different metro stations this morning, one of them, the stations were told by our producers here located just one stop apart but more importantly, one of them is the exit sean entry point for the European Union, alex, so it does appear very much as if this is a coordinated attack this morning. Reporter that was the major fear and in the past few months after paris. Paris, of course, showed us all that these types of highly coordinated and very deadly attacks can take place under the noses of the police. It had been in the plan in the works for a long time and get the authorities were not able to pick up on it. 130 dead at the end of the day at major sites across paris. The fear out of that, uk, in france saying that they feared more of the same. But not just coordinated attacks within one city but coordinated attacks across cities so when these first explosions happened at 8 00 at the airport this morning, if youre an intelligence official, immediate assumption is going to be where else could this be taking place. We as a News Organization were thinking where else could this take place . And on our way walking to the airport, the first reports came out of explosions at the metro. So this does appear to be a coordinated simultaneous attack, targeting the belgian transportation system, the airport airport, zaventem, one of the biggest of brussels referred to as the capital of europe, this is not only a very tactical attack but very symbolic. And the terror level going to maximum level in the wake of the airport explosions, now we have the reports of the three more stations, the entire subway system closed at this moment. Give us another sense of whats going on there. Youre seeing the crowds of passengers leaving the airport. You mentioned you saw someone wounded. You said it was a pretty calm scene. Not chaotic. Are people visibly i would imagine its pretty jarring and getting word of other things happening in the city. Reporter when i say its not chaotic. I mean that people are not screaming running around of concern. You can see it on their face, orderly. I should highlight that. These explosions happened just under two hours ago and people are still streaming out from the airport by the hundreds. By the thousands. But it is very orderly. People walking very calmly, obviously ny no smiles on their faces but you dont see too much trauma. There isnt much crying or to be trying to figure out now where to go. They cant take their flights out of here and likely hearing of other attacks that are now taking place in brussels. The police are funneling them away from the airport towards an overpass and were see more and more buses coming to pick them up. So, alex, lets im going to ask to pull up that map once again to show you a sense of where were talking right now. Terror has struck the european capital, you would say, of belgium this morning and it first started around id say 3 00 east coast time, 8 00 belgium time getting this from the Prime Minister of belgium saying there were two explosions in the departure hall around 8 a. M. Local. Thats about 3 00 eastern time here in the u. S. , the possibility of a terrorist attack is being investigated. Our priority is to secure the area. There have been many injured. Has been raised to four, the maximum alert with special emphasis on transport hubs, airports, stations and Nuclear Plant s plants but also releasing that statement but that came out prior to the word of the other explosions at the train stations this morning. We should mention injured have been taken to a hospital where a crisis plan has been activated so the city reacting to what is going on in brussels this morning. The metro stations are closed following records of those explosions on the three different subway stations, all separate from one another following the two explosions and the departure hall of this Brussels Airport around 8 00 a. M. The time as alex explained peak time for people to be moving through the city, commuting through the city and now everything is coming to a close. Transportation shutting down. Alex, we should point out were getting word that other europe are being beefed up at least with security. Heathrow, of course, in london, charles de gaulle, of course in paris, many of these airports are beefing up security understandably after this mornings incident. Reporter were the belgian Prime Minister put out a statement confirming the explosions at the airport this morning. In the departure hall saying right now its the possibility of a terror attack that is being investigated. In mention of possible attacks in downtown brussels but has been raised to 4, its highest alert level with an emphasis on plants as you just mentioned. Confirmation at least one there was an explosion at one metro stop and there are reports from belgian media there were two others, as well. Well give him a quick break and on the phone abcs consultant john cullen who is our terrorism consultant. John, can you hear us . Yes, i can hear you. It would appear to be a Worst Nightmare playing out in belgium. Yes, it appears things are not going in the right direction. If one explosion possibly could have been something that was un unrelated to terrorism but if the reports are true, that there are multiple explosions, taking place in multiple transportation facilities, this would have the earmarks of a terrorist attack. John, can you give us a sense of your reaction to this in the recent arrest of Salah Abdeslam . Well, weve been hearing warnings from Law Enforcement and intelligence authorities for months now about their concerns that there could be hundreds if not thousands of people in europe, United States and canada who have been inspired by the ideology of groups like isis. While the arrest in brussels was a welcome sign from the standpoint of the terrorist attack in paris, that should, you know, that doesnt diminish the fact that its a significant threat facing europe that remains. And, john, as we keep you on the line we have new video we want to call up here in a moment of the smoky subways as we mentioned and look at that. What a horrifying scene that is right now. This is the scene playing out just within the last half hour or so in downtown brussels. One of three metro stations that were attacked this morning. It would appear to be attacked where you had three explosions of that location right now. John, i dont know if youve gotten a chance to look at many of the images that were getting. I know its fairly early but any sense when you look at the impact of all those explosions there of the explosions there at the airport, any sense of what might have been used or how this might have happened . Its too early to tell and the investigators are obviously looking at this first and foremost, security authorities are going to try to gain control of the situation. They are going to, you know, provide aid to those who are injured at these locations but they have got to figure out if theyre more attacks coming and stop those attacks for the safety of the citizens in the city are going to be the most important factor on security official officials mights at this point. Can you walk us through what Security Officials will be doing right now. We know the terror alert was raised to the maximum level after the explosions, the metro completely shut down and airport all Flights Canceled or diverted. Nothing is going on there now. So what are authorities going to be doing as we speak in reacting to this news coming out and whats going on in the city right because theyre unfolding theyll try to get people off the street. If you havent seen it youll see a massive influx of uniform Law Enforcement and military personnel. Particularly around congregate. This is a difficult one because authorities have already been saturating the community trying to arrest People Associated with the cell that conducted the paris attack. So from an investigative perspective, theyre already, you know, knocking on as many doors as they possibly can. I think right now, what youre going to see and they may require some assistance from the see just a massive, massive security presence on the streets of brussels. Once again were talking with abc terrorism contributor john cohen joining us on the line following the explosions that took place and rocked the capital of belgium this morning. And, john, you know, were getting these reports at one of the subway stations or metro stations attacked near the European Union office there is in belgium and also you have this airport that was attacked. Any significance that you could kind of glean at this early hour of the locates that were selected . I think, you know, its early, that will all come out through the investigation. But these are places where they kong get great and in particular if an attack plan had to be speeded up because of the arrest over the past several days then people who are carrying out these type of attacks will go to with others, can go to places where there are large crowd so this cause as many casualties as possible. Secondly, the significance is that, you know, if you can shut down the transportation infrastructure of a city you shut down the city. And theres no other way to have the most dramatic impact on a community or a city like brussels by shutting down its transportation systems. You know i first want to emphasize the possibility of a terrorist attack is being investigated, nothing has been confirmed. Nothing been said beyond that officially by the Prime Minister, the word from the Prime Minister from a spokesperson this statement that was put out a little earlier. We know the threat level was raised to the highest level. We know before this, john, that the threat level was raised. It just wasnt at the highest level yet. Given that context heading into this morning are you surprised at these if these were attacks that they were able to this airport and at these subway stations . Yeah, i think, unfortunately, nothing much surprises me anymore. You know, weve been hearing through reports such as those on our network and others about the concerns that there was a much larger presence, a much larger set of operatives, you know, located in that city and in that region. Again, this shouldnt be a surprise to anybody necessarily because there have been concerns that have been raised by European Union officials, the u. S. Officials over the last several months about just the breadth of the threat posed by those either recruited or inspired by isis and other terrorist organizations. We want to get the very latest that we have, confirmable as of abc news right now so you have two explosions that took place at the airport around 3 00 eastern time, roughly 8 00 belgian time this morning. All airport operations suspended some kind of incident involving the brussels metro. We believe three different incidents at three different locations, that is what were getting from belgian media so its been quite a morning so far there in brussels. We should mention according to the ap at least one is dead in that Brussels Airport explosion, there are numerous injuries at both the airport and the metro station near the eu headquarters according to the ap what we know of the damage or the reported damage in the wake of these attack or excuse me, these explosions. We know theyre explosions but not whether theyre attacks yet. According to the Prime Ministers statement but as far as the injuries and that have resulted there are numerous at both the metro and airport and one dead. You said theres been a lot of chatter with a lot of the networks that you guys deal with. Youve been hearing that there might possibly be a plot . Reporting yesterday from belgian officials that some of the results from the interviews that were taking place with individuals that have been arrested of late gave them caused concern that there was an existing network out there associated with those that carry out the paris attacks and additional plots may have been in the process of being planned. That said, you know, i think unfortunately the times were living in right now and based on everything weve seen over the past year, year and a half, just has to, you know, we just have to remind everybody there are people out there that we may not know about that Security Services may not know about who are intent on committing an attack in the name of ideology, the ideology of a group like isis so this is just in the sense the new normal wane and we its a very real possibility in city as cross europe and the so give us a context of what you expect to be the reaction in cities across europe. I know i have a statement from the heathrow spokesman saying that we take this safety and security of our passengers and colleagues very seriously and in light of the events at the Brussels Airport were working with the police at heathrow who are providing a high visibility presence. They expect flights to the Brussels Airport to be affected as you would suspect considering that all flights have been airport. So obviously other airports reacting. How do you expect europe to be reacting this morning . You will see an increase in security across the European Union, i suspect. You will see there will be an impact on flights throughout the region and perhaps internationally. You will likely see an increase in security presence in mass transit stations and other potential socalled soft targets or people locations where people i think we will also i mean american officials will be monitoring whats going on, as well. There are a large number of flights that come to the United States from the European Union and obviously they will be wanting to evaluate whether theres any security implications to the u. S. All right. That would be john cohen joining us, breaking now. Terror attack in brussels. Explosions rock a crowded airport terminal. And now reports of an explosion at a nearby airport. Well bring you the latest on this breaking news. The Vice President of the United States is in the tristate today. Where he will be speaking today. And traffic problems it could be creating for your morning commute. Not going anywhere. What coach mick cronin is telling our crews after rumors swirl that
