And capital. Theres no doubt this is a sophisticated attack and paralyzing yet again a major western capital. Two explosions happened at Brussels Airport and an explosion at a metro station in brussels. Eyewitnesses described a really heartbreaking scene. Lots of people whose hands were covered in blood. Everything is black. I think most people indistinctively like us knew the airport was under terrorist attack. Perpetrators of the a attack in paris operated. This was an attack on belgium. But it was really an attack on europe. Translator you need to remember always remember the seriously of terror attacks. President obama wraps up his first full day in havana, saying a new day for u. S. cuban relations. The fbi may not need apple to unlock a terrorist iphone. An outside party has come forward to unlock the phone. A race for the white house heads west today. Nominating contests will be held in idaho, utah and arizona. All that matters. You look at some of the country and look at whats going on throughout the world you look. But you look at what just took place in brussels. Thats peanuts compared to whats going to happen. On cbs this morning. Lets be clear, terrorists threaten our value and way of life and they will never succeed. Welcome to cbs this morning. Charlie rose is off so Anthony Mason is with us. Much of the world is on alert today as multiple explosions overnight shook the capital of belgium. Two bombings hit Brussels International airport, at least one of them reportedly a suicide blast. Authorities evacuated the terminals, sending people running and that airport is still closed at this hour. Another bomb went off soon after that near a busy subway stop. Officials say at least 36 people have been killed and dozens wounded in these attacks. Two americans are confirmed to be among the injured. Were expecting from hear from president obama from cuba about the attacks in just a few minutes. Well bring you those comments live. In brussels, the airport and subway station are about eight miles apart. Transportation into and within brussels is shut down. Charlie daggett is at Brussels Airport to begin our coverage. Charlie, good morning. Reporter good morning. The entire perimeter of the airport has been sealed off by security personnel and this remains an active scene. We understand police carried out a controlled explosion in that area where the attacks first began this morning. Witnesses said they started with somebody shouting in arabic followed by two explosions. Terror, moments after a suicide bomb detonated in the checkin area of Brussels International airport. The wounded were hit by glass and ceiling tiles. Blast injuries more familiar on the battlefield than a european city. This reporter was inside when the explosions went off, from sky news. Explosions were very, very loud, dust coming from the ceiling, panic. They were trying to find shelter from where they were. Reporter passengers were orred to leave in a hurry, leaving hand luggage behind, just evacuate. Americans andrew and denise bran the were waiting for a flight when they felt the shock waves. You feel like a wave go through your body. Felt muscles. I knew we were not very close to it. We were close enough that it reverberated. Reporter less than a half hour later, an explosion hit a metro station in central brussels. Belgian media reported several people were killed there. Journalist evan laamos was there. I had gotten on the metro, coming towards shuman. We were between stations when we felt a small blast of air and we heard some thudding in the distance. After a few minutes, someone came from the front of the metro to the back of the metro, opened up the metro door, installed a ladder and had us evacuate on to the tracks and walk back to the station. Reporter all Transportation Centers in the city were shut down as belgian authorities raised the terror alert to its maximum level. Now, the situation is so dire, theyre asking for volunteers to come forward and give blood. Theyre asking taxi drivers to give free rides to passengers because the Transit System has been paralyzed. We have learned Officials Say theyre going to try to open up a couple train stations later this afternoon with more security personnel on guard. Anthony . Charlie, thank you. Belgium is at its highest terror alert level. The explosions came just days after Police Arrested the only surviving suspect of the paris terror attacks. Elizabeth palmer is in london, elizabeth, good morning. Good morning. Hes Salah Abdeslam, and he was arrested in brussels on friday. Of course, investigators are now looking at the likelihood that todays attacks are connected to or were even prompted by the fact that Salah Abdeslam is now in jail. Security officials in europe have been bracing for more terrorist violence ever since the paris attacks last november. Belgian police knew they had not completely unraveled the network of radicalized young men, many of whom fought in syria who carried out or supported those attacks. The network is bigger than anyone realized. Most recently the police put out an apb for 24yearold najim laachraoui, a belgian citizen. Laachraoui is believed to be the bombmaker behind the paris attacks. His dna was found on remnants of the bombs and in a safe house used by the attackers. In fact, he may have actually rented the house in the belgian town of officialvelet. He is believed to have travelled with Salah Abdeslam. Salah abdeslam was captured during a raid last friday in brussels but had been able to evade capture for months. Last year, 30 people were convicted by the belgian courts of belonging to isis and the terrorist network in europe. Its now looking as if that is simply the tip of the iceberg. Norah . Ebusiness bElizabeth Palmer, you. Brian carroll thank you so much for joining us. What did you see . Did you have any idea that you were in danger . No. Actually i live in brussels. I was going i normally dont take the metro. I had a conference. On my way to the metro, i saw on my smartphone that there had been attacks at the airport and actually had a moment of hesitation on the metro this morning, thinking transportation wasnt the best idea. But i got on and literally minutes after i stepped on the train it was attacked. We were pulling into the malbek station. Everyone dropped to the floor. People were crying and scream g screaming. Others were yelling for everyone to calm down. I went straight to the floor. We were waiting there. There were multiple explosions. You could hear and feel them. Eventually some of the passengers went to try and open the door which was locked because the power had gone out. They werent automatically opening. I was right flex to the door. Me and some other passengers physically pried open the doors. And, you know, i didnt know what was happening. I didnt know if the attack was happening on the train itself or if it was happening at the station. It sounded like explosions. I didnt know if it was perhaps gunmen as well. I had a moment of do i stay on the train and wait and hope it goes away or do i mac a run for it, not knowing whats on the other side of the platform. And i decided to go make a run for it. You know, i took kind of stayed to the side and ran out to the exit. It was clear there was debris everywhere, smoke everywhere. Glass. As i was exiting the metro, people on the streets were looking into the metro wondering what was happening. It happened very quickly and then but it was clear as soon as it happened it was a terrorist attack. Brian, i just want to be clear here. You need as you were arriving in the train station you heard an explosion, not sure whether it was on or just off the train. Correct. Then how long after that you heard additional explosions . The train had stopped and i heard explosions as i was on the ground in the train. The pictures that were seeing, brian, are frightening. What youre describing is also terrifying to me. Its interesting that you said you had a moment of hesitation when you heard about the explosion at the airport. What made you hesitate . Well, you know, i mean, weve known ive been living in brussels 2 1 2 years. Over the past couple months we know theres been a terror attack, terrorist threat. Obviously what happened in paris was just months ago. The belgian government has been conducting raids and obviously a lot of the terrorists were identified were home grown in belgium, which is disturbing. So, you know, i knew this was going i weve had the threat of this happening for a long time. But you know, i heard about there were attacks, there was a bomb at the airport and, you know, as i was going to the metro, i kind of thought maybe Public Transportation isnt the best way but what are the chances of this happening . This is by far the most practical way to where i was going. You know, i always think when i travel, i dont want to be afraid. We have to live our daily lives. Brian carroll, thank you. President obama has been briefed on the brussels attacks while on the final day of his visit to cuba. Margaret brennan is traveling with the president. What do you expect well hear from him . This speech was supposed to be an address to the cuban people. Now the world is watching and the white house is keenly aware that president obama has to pick his words very carefully. Hes going to try to reassure the public about their safety, back in the u. S. , but also say to americas allies that the u. S. Is willing to help provide any kind of support to track down these attackers. And the reason that the white house will be so careful this time is because they did regret after those paris attacks back in november, that they underestimated how much fear that caused among the american public. They felt they really miscalculated. The president today will try to reassure them. Hes also going to be very careful here when he talks about what appears to be a rising death toll. We know that americans were injured in this attack. Because the state department is still trying to track down family members and trying to take account of all the u. S. Citizens in brussels, hes going to not want to address them by name or say exactly what the latest read is there. Now, the big picture here is that both european and u. S. Officials tell me they see this, not just as an attack on belgium but an attack on the international community. Remember, this city is home to the nato military alliance, the european union, it is a hub for the international community. And that is really a lot of the language saying this will be an international response. We are allied strongly against isis here, while it does appear that is the discretion many officials are pointing towards, its not clear yet if the white house is willing to say who they believe carried out this attack. So the words will be chosen very carefully here, norah, but very focused on reassurance and calming fear, as you say, that so many are feeling right now. Indeed. Margaret brennan with the president in havana. Thank you so much. And when the president comes out at any moment, we will bring you a special report here on cbs news with his comments. In the United States, major cities are stepping up security here. Je we go to washington. Those are precautionary measures to assure the public. At this time, officials are saying there are no threat against the u. S. And their Security Posture overall has not change. What you will see are efforts among major transportation hubs across the country, new york, for example, washington, d. C. , where you will see an increased Law Enforcement presence. That is outside the Belgian Embassy where there is new York Police Department vehicle and officers stationed there as well. Again, this is a precautionary measure. No threats against the u. S. , according to multiple u. S. Officials weve spoken with this morning. The focus now is helping as much as possible, helping european officials, in fact, since the paris attacks, there has been increased coordination on intelligence in this effort to track suspects down. We expect to see the same thing there today in this effort to account for all americans who may have been near the explosion site. That continues as well. There is concern for all of americans, all americans who may have been injured. But one u. S. Official telling me there is concern about accounting for all u. S. Service members who may have been in the area at the time of the explosions. I was specifically told that there is a u. S. Service member and his family who may have been injured. Right now u. S. Officials are trying to confirm that information but caution that this is still a very fluid situation. Anthony . Jeff pegues, thank you. An unexploded suicide vest was found at the Brussels Airport after the attacks. An Army Bomb Disposal team was called to the area and the sound of a controlled explosion was heard. And we want to pause to bring in our cbsg thank you. Thank you so much. Thank you very much. President castro, the people of cuba, thank you so much for the warm welcome that i have received, that my family have received and that our delegation has received. It is an extraordinary honor to be here today. Before i begin, please indulge me. I want to comment on the terrorist attacks that have taken place in brussels. The thoughts and the prayers of the American People are with the people of belgium and we stand in solidarity with them in condemning these outrageous attacks against innocent people. We will do whatever is necessary to support our friend and ally, belgium, in bringing to justice those who are responsible. And this is yet another reminder that the world must unite. We must be together, regardless of nationality or race or faith, in fighting against the scourge of terrorism. We can and we will defeat those who threaten the safety and security of people all around the world. To the government and the people of cuba, i want to thank you for the kindness that you have shown to me and michelle, malia, sasha, my mother in law. Marian. [ speaking a Foreign Language ] its famous president obama speaking addressing the situation in brussels before remarks to people in havana, cuba, the president said well do whatever is necessary to support our friend and ally, belgium.
