anyone to come to this country that we cannot vet to make sure that they are not radical islamic terrorism. >> the last thing we need, my friends, are leaders who incite more fear. and terror becomes the focus on the campaign trail, as voters in three states head to the polls. good morning from the studio 57 newsroom at cbs news headquarters here in new york. good to be with you. i'm anne-marie green. well, the latest announcement from isis following the brussels bombings is a dire threat, promising what is coming is worse and more bitter. yesterday's deadly bombings rattled europe and shut down the belgian capital. two men believed to have been suicide bombers. they were brothers known to police. police are looking for the third man wearing the hat who was being sought before yesterday's

last year's paris attacks. three bombs killed at least 31 people and injured about 250 others. the first victim to be identified is ruiz of peru. she was at the airport with her husband and her twin daughters. johnathan vigliotti begins our coverage from brussels. >> reporter: brussels airport remains closed for the second day in a row. the city of brussels, though, is slowly coming back to life. we have been garbage trucks taking their daily routes and we have seen cars on the streets and people walking on the sidewalks and buses packed with people heading to work. much different scenario what unfolded yesterday where a block away from the train station that came under attack. you can see it is still closed, but police here on the scene, as they continue their investigation. all of this unfolding, of course, as police continue their search for at least one suspect that remains at large.

>> reporter: passengers ran in panic after a bomb exploded in the departures area of brussels international airport tuesday morning. a second blast followed. >> it was very loud. it was not something that sat on the ground or something. it was -- you felt kind of shocked. >> reporter: belgian police say these are the suspects. investigators believe the two men in black blew themselves up. they wore gloves that may have hid detonators and a hundred for the man in white wearing a hat. an hour later, a bomb tore through a subway station that serves the european parliament. >> we received a big blast of air and the train stopped. >> reporter: people scrambled through the dark tunnels to safety. belgian security forces have been conducting raids here in brussels and one of them, investigators say they found an explosive device with nails, chemicals, and an isis flag. americans are among the injured. one of the blasts at the airport

bellin to the ground. the belgian businessman played basketball in michigan. his father spoke to his son on the phone. >> he saw people dead and people dying, so that -- i'm sure that will stay with him for the rest of his life. >> reporter: belgian's prime minister warned more attacks could be coming. he has called for three days of official mourning. the u.s. state department has issued a travel advisory for all of europe, warning u.s. citizens to be vigilant. in brussels, johnathan vigliotti, cbs news. the attack in brussels came just days after the arrest of salah abdeslam, the suspected chief planner of those events. during the raid that netted abdeslam, authorities announced they were looking for another man, najim laachroui. we know he is linked to tuesday's attacks.

allen, authorities are aware of the three men they found on surveillance building they knew about the two men and the bomb maker. what can you tell us about these three men? >> reporter: well, the two men who were seen in the video believed to be the suicide bombers were known to the belgian police but the police said no link to terrorism. however, laachroui is another case altogether. apparently, his dna was found in an apartment used by the paris attackers. he is directly linked to that. they think he may well be the master bombmaker. he traveled to hungary last year with salah abdeslam to paris for the terrorist attacks there. authorities are arriving here to work with their european counterparts, specifically to look at the bomb and how it was made, because the more they found out about the specifics of

went into it, the more clues it gives them as to who id it and they can trace back perhaps to where he got the bits' pieces but it's a long, slow process. >> since friday, belgium has been on high alert but they weren't able to stop what happened yesterday. i'm wondering if the people of brussels are beginning to lose faith in the fact that authorities may or may not be able to protect them? >> i think that would be a natural thing, although people here do realize also this is a very difficult thing to do. you simply can't find everybody all the time. it's interesting. i was here after the paris bombings and this city was on a stage iv alert level and streets were closed and no public transportation was available here. and today behind there is lots of traffic and kid are going to school and public transport, with the exception of the line that was bombed, is open and running.

cautious and they, obviously, want their political and security people to get a handle on this, but i think europe is becoming attuned to the idea it's going to happen. you're not going to be able to stop it all and it can take all of the sensible precaution they can and get on with life and that is the way that you kind of hit back at them. now there will be a minute of silence here today, later on in the morning, to honor those who were killed but then people will get right back to business. they are nervous, but they are not running scared. >> we saw that in paris and i guess we're seeing it now in brussels. allen pizzey, thank you very much. dozens of americans were caught in the chaos of tuesday's attacks. it's unclear whether any u.s. citizens were killed or how many were hurt. but some who survived the attacks are sharing their stories, while others are waiting word from their loved ones. >> i was in line to check in and she was sitting in the seat with her husband waiting for me to finish.

after ending his historic trip to cuba. before leaving, havana, he attended a baseball game between the tampa bay rays and the cuban national team. the president was asked if he would skip the game, given the attacks in belgium. >> they can't defeat the world. they can't produce anything. they don't have a message that appeals to the vast majority of muslims or the vast majority of people around the world. what they can do is scare and make people afraid. and disrupt our daily lives and divide us. and as long as we don't allow that to happen, we are going to be okay. >> mr. obama said the brussels attack is the latest example of why the entire world must unite to fight terrorism. cbs news coverage of the attacks in brussels continues on "cbs this morning." we have a team of correspondents in europe. plus a look at the security status in the u.s.
