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. these two are believed to have been suicide bombers and brothers known to police. police are looking for the third man wearing the hat who was being sought before yesterday's attack and is believed to be the bomb maker, also involved in last year's paris attacks. three bombs killed at least 31 people and injured about 250 others. the first victim to be identified is this lady 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 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. [ screaming ] >> reporter: passengers ran in panic after a bombing exploded in the departures area of brussels international airport tuesday morning. a second blast followed. >> it was very loud. 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 hit 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 knocked 37-year-old sej belgiumin to the ground. 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 abdeslam, the suspected chief planner of those events. during the raid that netted abdeslam, authorities announced they were working for najim laachro laachroui. we know he is linked to tuesday's attacks. allan, 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: two the 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. laachroui, 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 year. authorities are arriving here to work with their european counterpart, specifically to look at the bomb and how it was made, because the more they found out about the specifics of the bomb, the expertise that went into it the more clues who did 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 authrities 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 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. people are being weary and 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 with 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 seeing it now in brussels. allen pizzey, thank you very much. dozens of americans were attacks. it's unclear whether any u.s. sis 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. nauk [ inaudible question ] >> i have no idea where she is. >> reporter: they haven't heard from the couple since the brussels airport attack. they were dropping off stephanie's mother at the airport when the terrorists struck. justin's brother says the state department told his family, the tennessee couple is not on a casualty list. >> this is a picture of them

running through the airport after the blast. >> reporter: quinnipiac university students here were in the airport for about ten minutes before the blast went off. after flagging down a car outside the airport, the students spent the night as a u.s. embassy worker hems and say they are continuing their trip through europe. >> she is telling us she is planning on continuing her trip because if she doesn't, they win! so she's going. >> reporter: three american mormons missionaries were hurt in the explosion and not a brush of terrorism for one of them. mason wells was a block away from the finish line at the 2013 boston marathon when a bomb went off and he was at his home mission at paris when last year's attacks happened. the family of one of the other missionaries joseph empey says he is in good spirits. >> we love him a lot and hopes he gets all the way better.

>> the justice department says an air force family of six were taken to the hospital. the unidentified air force service member is stationed at a base in the netherlands. jeh johnson says no incredible intelligence pointing to an attack in the u.s. but the brussels bombings stepped up security in this country. extra security was employed at major airports and transit hubs across the u.s. security officials are considering additional screening for air travelers coming from belgium into the u.s. president obama is in argentina this morning and arrived in woubuenos aires overnight. 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 after given the attacks happening in

belgium. >> 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. now to the race for the white house, where, this morning, both front runners maintain comfortable lead but they failed to dominate yesterday's race. donald trump easily won the republican primary in arizona. and all of its 58 delegates. but ted cruz scored a key victory winning utah's gop caucus and appears to be on track to take all 40 of its

delegates, slowing trump's efforts to get enough delegates to clench the nomination. on the democratic side, bernie sanders won the idaho and utah caucus and such a huge turnout that votes had to photo copy fresh ballots but hillary clinton easily won the arizona primary. talk of the attack in brussels and how to respond to isis dominated the campaign trail. don champion has that part of the story. >> anywhere where there is a local of radicalization and where there is an expanding presence of radical islamic terrorism, we need law enforcement recourse directed there and national security sources directed there. the object to is to keep everybody safe. >> reporter: ted cruz the united states needs a president to stand up to its enemies and donald trump agreed saying they should scale back its commitment to nato and suggested that the

belgium attack could have been prevented. >> he'll talk a lot faster with torture. if he would of talked, you might not have had to blow up all of these people dead and all of these people horribly wounded. >> reporter: last night, hillary clinton said now is not the time to panic. >> we can't throw out everything we know about what works and what doesn't and start torturing people. what donald trump, ted cruz and others are suggesting is not only wrong, it's dangerous. >> reporter: and bernie sanders said america should not isolate itself in the world. >> we will destroy isis through a coalition in the middle east, led by the muslim nations themselves. >> reporter: this morning the nation's largest muslim civil rights said cruz's message sends
