man on the right of this photograph. officials believe the men on the left were the suicide bombers who attacked the airport. we put together some of the pictures and the sounds of this day. [sobbing] [screaming] >> the terminal is closed down. all the luggage stays here! all the luggage stays here! smoke. i didn't know exactly where the explosions happened. i know there are two explosions. and when i was outside, i tust saw two people covered with blood. a lot of people's hands were covered with blood. it's the first time i saw such a thing in my life.

don't take it with you. >> i was in the metro heading to maelbeek, and we received a big blast of air, and the train stopped. >> your attention, please. >> we had the normal recording announcement. >> an incident has just occurred on the line. we are currently trying to resolve the problem. >> so we waited, and then smoke began to enter the carriages. >> after a few minutes someone came from the front of the metro to the back of the metro. [sobbing] opened up the metro door, installed a ladder and had us evacuate on to the track. >> pelley: charlie d'agata has been on the scene at the airport

he now has the latest on the manhunt for us. charlie? >> reporter: yes, well, it is the man in white hat belgian police are asking the public for their help. as you mentioned in the earlier report, they believe the two men in the left of that photo they distributed this afternoon killed themselves in the initial attack. they believe the one on the right got away. and they have been conducting raids and manhunts throughout the day, and we have seen them ourselves. certain neighborhoods in brussels, one of those raids uncovered two bombs and some explosives devices and an ice ace flag, again a direct connection to the attacks here at the airport today. we also have to mention, you know, the country is at its highest alert level now, so you have an incredible police presence, especially around the sort of contested neighborhoods in brussels and molembeek and other areas.

that they have enlisted tighter border controls. so this manhunt is very much under way, specifically pointing to parts of certain neighborhoods in brussels, but, of course, they want to control the borders, as well, and i guess what they're asking themselves is in the chaos of what happened here earlier today, how a suspect like that could have slipped away, but we have seen it in the past. >> pelley: charlie, as you look at that picture with the two suicide bombers on the left-hand side of the picture, the man in the black hat on the right, the subway attack occurred about 79 minutes after the airport attack. is it possible that the man in the black hat could have been the one who attacked the subway? >> reporter: in terms of timing, it is definitely possible. on a normal day it would be easy to reach central brussels, that part of the capital from the airport. whether that could have happened or whether it would have even been easier to happen during that time in the immediate

now, we were racing to get here and get as close to the airport as we possibly could. we were stopped from getting close to it, but hardly anybody was stopped from getting away from it for obvious reasons. so although there was a lockdown around the airport in the immediate aftermath of the attack, in terms of people trying to get away from the airport, they weren't stopping anybody. >> pelley: charlie d'agata in brussels for us tonight. charlie, thank you so much. the attacks today came just days after the arrest of a fugitive from the november attacks in paris, which killed 130 people. europe is on the alert for more such attacks. here is elizabeth palmer. >> reporter: across europe heavily armed police flooded into public places and set up checkpoints on normally open borders while politicians, including britain's david cameron, spoke of solidarity. >> we need to stand together against these appalling terrorists and make sure they can never win.

security is to prevent more attacks, of course, but it's also to reassure nervous travelers. >> i think it will make people feel safer, but i don't know if it will stop the attack if it's going to happen. >> reporter: in france, still on edge after the paris massacre in november, 1,600 extra police officers were on duty, especially in railway stations and airports. but just as important in europe's response is what you can't see. as president francois hollande said, "the war against terrorism in europe must be fought especially using intelligence." to do that, though, richard walton, former counter-terrorism chief for scotland yard, says europe's security agencies have to share information better. >> there's more to be done about the join-up between intelligence agencies across europe where the borders are more porous, there is more availability of firearms, and where sometimes

communities is not as good as it could be. >> reporter: after six terrorist attacks on european soil since the beginning of last year alone, there's never been such pressure to get it right. the u.k. has publicly been very supportive of belgium today, after all, it's a close neighbor, just a couple hours away by train, scott, but the government did warn britons not to travel there in the near future unless they had the most pressing kind of business. >> pelley: liz palmer, thanks. until january cbs news consultant richard walton was the head of counter-terrorism for the london metropolitan police. richard, let me ask you, what did you learn today from the attack? >> well, sadly what we've seen today is the second wave of complex terrorist attacks in europe directed by isis

with tragic consequences. >> pelley: the european union has been trying to integrate in many different ways, but today raises the question of whether the intelligence organizations among all of these countries are talking to each other sufficiently. >> reporter: i think european countries have been struggling with the challenge that this threat presents. obviously isis, islamic state has been targeting the european countries since september 2014 when a fatwa was made against european capital cities. the european countries have been struggling i think to coordinate the effort to thwart this threat. that's within countries itself within europe, but also across countries. it's difficult enough for police agencies to link up and integrate with their intelligence services to

to work across country, across europe where the boundaries are so porous in modern times. >> pelley: is it possible for european intelligence to keep eyes on every one of the suspects that they'd like to watch? >> reporter: one of the biggest challenges from this threat has been the volume and the volumes of individuals and the numbers of individuals that have actually traveled. if you go back to al qaeda, it was a small number of individuals from europe traveling to the fatah region of pakistan and afghanistan, whereas now you're seeing hundreds, thousands of extremists from across european states and indeed other countries around the world, north african states, and elsewhere, traveling to syria. and what we're seeing now is the threat they pose when they return back to their european homeland, trained as terrorists and trained in training camps in syria. >> pelley: richard walton,

for willed's metropolitan police. among the americans wounded today are members of a military family and three mormon missionaries from utah. danielle nottingham is in salt lake city with their story. >> reporter: just moments before the plarks 19-year-old nathan wells, 20-year-old joseph empy and 56-year-old richard norby were in the terminal saying good-bye to french missionary 20-year-old fanny rachel clain, who was headed to ohio for her assign. all four went down. wells of utah was rushed into surgery for his wounds. family spokesman lloyd coleman. >> had some burns we understand to his face of hands, but the biggest concern is about his foot. it sounds like his ankle and his heel is hurt the worst by some playing the debris or shrapnel from the bomb. >> reporter: this was not wells' first brush with terrorism. in 2013 he was a block away from

marathon. and last november he was at his home mission in paris during the terror attacks there. joseph empy, seen here in this recent video, suffered a leg wound and second-degree burns to his hand, face and head according to his family. empy, who is from santa clara, utah, posted these photos on his blog yesterday. richard norby, of lehi, utah, was knocked down during the explosion and may have broken a leg or ankle. he's in charge of the missionary program in which the younger members worked. the head of the mormon church here in salt lake city has been in touch with the wounded and their families. scott, in a statement, the church says its thoughts and prayers are with the people of belgium and france as they deal with the devastation caused by these attacks. >> pelley: danielle nottingham for us tonight. danielle, thank you. president obama left cuba tonight for argentina. he was in havana when he got word of the attacks in brussels

to change his travel plans. margaret brennan is with the president. >> reporter: in a secure call early this morning, president obama was briefed on the bombings. >> we will do whatever is necessary to support our friend and ally belgium in bringing to justice those who are responsible. >> reporter: but at his keynote address and with the cuban leader rauu l castro looking on, the president quickly turned back the his historic trip. >> i have come here to bury the last remnants of the cold war in the americas. >> reporter: he out thed the benefits of democracy to a still-authoritarian country and pointed to america's presidential campaign as proof that anything is possible. >> you have two cuban-americans in the republican party running against the legacy of a black man who is president while arguing that they're the best person to beat the democratic nominee who will either be a woman or a democratic socialist. who would have believed that back in 1959?

president and first family joined castro at a baseball game between the tampa bay rays and a cuban national team? >> we condemn the act of terrorism in belgium, for this we request a minute of silence. >> reporter: after a moment of silence for the victims in belgium, the mood lightened. the two leaders did the wave and cheered a play at the plate. president obama told espn that changing his schedule would have let the terrorists win. >> what they can do is scare us and make people afraid and disrupt our daily lives and divide us, and as long as we don't allow that to happen, we're going to be okay. >> reporter: white house officials believe terrorism is a persistent threat but one that they can manage. and, scott, the president feels strongly that it shouldn't dominate the u.s. agenda. >> pelley: margaret brennan covering the historic trip the havana. margaret, thank you.

the baseball game in cuba had some of the presidential candidates crying foul. and nancy cordes has that. >> i'm a little surprised that the president is going to a baseball game. >> reporter: in minnesota, ohio governor john kasich said he would have flown right home. on fox news, donald trump made this proposal. >> i would close up our borders to people until we figure out what is going on. >> reporter: but he reversed himself a half hour later on cbs. >> new york i didn't say shut down the borders. >> reporter: then flipped again on facebook business. >> we have to close our borders. >> reporter: trump suggested yesterday the u.s. should scale back its involvement in nato, which is based in brussels. >> donald trump is wrong. that america should retreat from europe, retreat from nato. >> reporter: texas senator ted cruz suggested today that u.s. law enforcement should patrol and secure muslim neighborhoods before they become radicalized. >> i don't like this.

>> we are fighting a terrorist organization that is killing innocent people. we are not fighting [inaudible]. >> reporter: campaigning in washington state, hillary clinton said she'd wage a cyber war against terrorist recruitedders. >> where some of my opponents want to build walls and shut the world off, well, you tell me, how high does the wall have to be to keep the internet out? >> reporter: this is a critical night for all five candidates with contests in arizona, utah and for the democrats idaho, as well. tonight we learn, scott, whether sanders is right, he can dominate the west, and whether cruz and kasich can do anything to halt trump's momentum. >> pelley: nancy cordes on the campaign.

the attacks in brussels

airport bombs exploded in the departure area before the security checkpoint, which is, of course, open to anyone. transportation correspondent kris van cleave looks at what can be done to make airports safer. >> reporter: at airports across the country, from the nation's capital to california, passengers were greeted by a heavily armed, stepped-up police presence. officers checked arriving vehicles outside of new york's j.f.k. airport. in miami, cart lodes of customs officers patrolled the departure area, but the attack in brussels exposed a vulnerability at all airports, the area before security checkpoints, the curbside, the ticket counter, even the line for coffee. >> how do you best fix this recognizing there is no perfect system. >> reporter: john pistole. >> do you bring in additional officers and pay overtime? how many dogs do you have? and once you start that, how long do you sustain that? >> reporter: the t.s.a. said

at some airports, but it did not announce plans to push security frim -- perimeters back the cover softer targets. last march a new orleans man was shot by airport police while wielding a machete in the unsecured area of the city's airport. in 2013, an armed man walked into lax and killed a t.s.a. officer outside the checkpoint. >> we're dealing with large volume of people in confined spaces that are relatively easy targets. >> reporter: ron hosko is a former assistant director of the f.b.i. >> we cannot secure every space. we can in the secure every space in america where people congregate, quarter. gather. we cannot do that effectively, and i believe that our intelligence services and law enforcement working as hard as they are are able to do it less and less effectively now because of the reality of encryption. >> reporter: by encryption, hosko is talking about secure apps and phones that allow terrorists to talk to each other undetected.

today for enhanced airport security. but bottom line, at any checkpoint on that other side where people are lining up to be screened, that is a soft target. >> pelley: kris van cleave at reagan national tonight. kris, thanks very much. one neighborhood in brussels has

>> pelley: in the molembeek neighborhood of brussels, it has become known as a recruiting ground for isis. several of the paris attackers were from there, including salah abdeslam, who was arrested there on friday. well vladimir duthiers went to molembeek recently to learn more. >> so this is number 30. this is the home of abdeslam, one of the men whose car was found near the bataclan theater. you can see we're literally across the street from the town hall. this is where he grew up.

supposedly responsible for planning the paris attacks, he also grew up in molembeek. these guys were friends. they grew up together. the question is what happened? what happened to take them from this community to to this horrific attack committed in paris on friday the 13th of november? >> pelley: vladimir duthiers. our digital news network cbsn has continuing coverage of the attacks, including an investigation of radical islam inside belgium. you can stream cbsn on your apple tv or roku device. you can also get it at cbsnews.com. in another story today, rob ford has died. he was the former mayor of toronto who confessed to smoking crack while in office and became a frequent punch line on late-night talk shows. colorful is one way to describe ford. he once knocked over a female
