bakraoui brothers, born in belgium, had extensive criminal histories. but that they knew of no ties to terrorism. this afternoon, we learned that is not true. in fact, last june a worldwide alert about khalid el bakraoui saying he was wanted in belgium, the charge, terrorism. and today turkey's president saying that same month, brother ibrahim el bakraoui was caught on the syrian border and deported to europe. the belgian authorities were warned he was "a foreign fighter." >> what's now clear is the paris attacks and brussels attacks were all of one cell. one cell that straddled the two borders. >> reporter: bombmaker najim laachraoui was well known to authorities, the bomb found in that apartment a signature of isis bombmaking found in seven places across paris. >> the materials in the apartment suggest more bombmaking in progress. they had the precursors there in fairly large quantities. >> reporter: those three suitcases seen in the surveillance photo believed by police to be the likely source of the explosions. >> one of a small group of explosives that can function in so in a laptop. in a shoe. in underwear. there are others but this is one that goes under the classification of homema

officials say it was khalid el bakraoui. he rented the brussels apartment that served as the hideout. khalid's brother, ibrahim el bakraoui and najim laachraoui both wearing black in the photo were the suicide bombers at the airport. laachraoui has been on the run since the paris attacks. now the third man who dropped his bomb off at the brussels airport and left, the man in the light jacket and hat and glasses, he is still on the run. he is the subject of the intense manhunt. police conducting raids raising the questions did the men in the pictures act alone? are there other members of the terror cell out there? cnn's fred pleitgen joins us. it is alarming. still unidentified terrorists on the run. >> reporter: yeah, absolutely. it's one of the things the belgian authorities are worrying. they say potentially people who are dangerous and could plot further attacks. when the police caught salah abdeslam on friday, they said they believed he was part of the new network forming and planning attacks. three days later, we had att

about an hour later, police say ibrahim's younger brother, 27-year-old khalid bakraoui, would explode his own bomb inside the molenbeak subway station. police believe all were part of a cell which includes abdeslam, who was arrested after four months of evading police. authorities now say that timing of yesterday's attack may have been triggered by that arrest. supported by a note found by authorities on the bakraoui, he wrote about being in a rush, no locker knowing what to do, being sought everywhere, spending the rest of his life next to him in a jail cell. >> those remaining members of the cell saw that their comrades were being picked off one day after another. and probably thought they had very little time left to conduct the next round of attacks. >> reporter: for the first time today the state department warns americans that there is a risk of imminent attack when traveling to all of europe. this morning, prosecutors revealed both el bakraoui brothers, born in belgium, had extensive criminal histories. but that they knew of no ties to terrorism. this afternoon, we learned that

he's the brother of khalid bakraoui, the suicide bomber who targeted the subway.. >> this is difficult work. it's not because we don't have the best and the brightest working on. it's not because we are not taking the threat seriously. it is because it's challenging to find, identify, very small groups of people who are willing to die themselves and can walk into a crowd and detonate a bomb. >> so we drove into brussels this morning and one day after the bloody attacks here, people are returning to work and to their activities, even if they're doing it with heavy hearts and certainly a little bit of concern. cal perry with me. you know, after the paris attacks that we saw last year, immediately afterwards we saw a heavy security presence deployed not just across paris but across france. there was a large manhunt under way. a similar scene in brussels but what's your reading of the streets today there a different feel. this is no the a city on lockdown. talking about a few hundred extra soldiers, police here in brussels. i drove in from paris. no checkpoints to bru

longer safe.>> turkey's supported ibrahim el-bakraoui because of suspicion that he was a terrorist fighter belgium could not identify link so his brother , khalid el-bakraoui blew up a train 7 miles away from the airport. as the investigation goes on, americans wait for their loved ones. they still have not been heard from with stephanie and justin scholz who are working in brussels at the time of the attack. stephanie's aunt spoke by phone. >> we were hoping we would hear something immediately . stephanie and justin had got into the car or gotten home or had somehow gotten at the airport. >> . robert: t atp was found an apartment in brussels where the attackers were living. t atp was a key ingredient in the explosive used in paris . that links the events. the associated press is reporting that isis has trained 400 fighters to target europe . that suggests that there are potentially dozens of more attacks. >> turkey sent him back saying we think there is a connection here and it will be tough for them to explain away. >> that reinforces what people have said about belgium. they have really failed to nab people right under their noses. >> there

they are being identified by belgian state broadcasters as khalid and brahim bakraoui. you can look at video we have for you this morning. this report this morning indicates these brothers were terrorism. reporters in brussels say khalid bakraoui rented an apartment in the operation that led authorities to the top paris attack suspect, salah abdeslam. this is the development, that third man in the photo, if you want to come back here, he has not been caught yet and i'm seeing some reports he has been identified, part of the story i'll be following throughout the morning right here from the alert center. back to you. >> john: wbtv is committed to bringing you continuing coverage of the terror attacks in brussels on air, our website and social media. we will update you as developments continue. >>> a big day in raleigh as lawmakers hold a special session to take on charlotte's non-discrimination ordinance. wbtv obtained a draft it it will consider. what gender is listedded oned on a birth certificate. the bill would keep local governmentses from enacting pay standardses w

that suspect khalid el bakraoui. the other suspect is seen holding a large bag but it is also possible that he, like el bakraoui, did not survive that subway explosion. >> thanks so much. >>> new arrests in germany are being tied to the brussels attacks. i want to go live to brussels and cnn's senior international correspondent clarissa ward. clarissa, first tell us what else are you telling us about this suspect that is now in germany? >> reporter: well, as you just heard there from brian, police found these two text messages on his phone. one of them mentioning the name of the subway bomber, khalid el bakraoui, the other one saying simply end. that was three minutes, three minutes before the metro bombing attack. now, we're learning a little bit more about how police found this man, though. reportedly this was a random check at a train station in germany. the man aroused some suspicion with his behavior. when they went and looked at his passport, they found that there was a ban for him on traveling freely inside th

ibrahim el bakraoui blew himself up at the brussels airport just before 8:00 a.m. that's him in the middle. his younger brother khalidhour later at the city's metro station. in the days before the brussels attack, investigators targeted a residence rented by khalid el bakraoui. he and his brother suspected of having ties to the attacks in paris last november. and paris suspect salah abdeslam, arrested last week. until now, the brothers had only been lunged to violent crime, never terrorism. in 2010, ibrahim el bakraoui was sentenced to nine years in prison after shooting at police. it's unclear why he was released. his brother khalid was arrested in 2009, the network says, and sentenced to five years in prison for carjackings. this is not the first time two brothers have instilled fear and caused bloodshed. in the paris attacks last november, salah abdeslam's brother detonated a suicide bomb. he died while his brother fled. also in paris in january last year gunmen forced their way into the offices of charlie hebdo magazine killing 12 people. the prime suspects, brothers sharif and saeed kuwashi. the brothers were in

khalid and brahim el bakraoui now identified. fred pleitgen is live for us right now outside an apartment they were renting. fred? >> absolutely. one thing that's stunning to many people following this case, first of all you always seem to come back to the same sort of group of suspects and also that the police apparently had these two men who now conducted these suicide attacks at the airport in brussels cornered at one point in time. it was last tuesday that police went to check out the apartment or the building that you see behind me, going to an apartment in there. they believed that apartment was empty. that's the reason why they didn't go in there with heavy fire power or with a whole lot of police officers. instead of finding the empty apartment, they were met by fun fire. people opening fire with ak-47s, they were able to take out one of the people who then turned out to be one of the main plotters of the paris attack, someone who had been in contact with the paris attackers as they were conducting those attacks on novemb

khalid bakraoui is shown here on the left. he carried out the bombing at the train station ab hour later. both brothers had ties to the paris terror attacks. authorities updated the death toll last hour too. it rises to 31 and the wounded rises to 271. we're covering all the angles to the investigation. let's begin with cnn's nima elbagir in brussels. that news conference was pretty surprising last hour. >> it was. it really broke down the detail. we're only just past the 24 hour mark. so there is a lot of information we had bln hearing earlier that now appears authorities had initially presumed but turned out to be incorrect. so let's break this down for everybody. 7:59 a.m. yesterday police believe when the first detonation happened. the first suicide bomber detonated. 37 seconds later the second bomb. then the third man, the one they are currently seeking, he left a bomb to be remote detonated and that horrifyingly seems to have had the largest amount of explosive. this was the bomb that was intended to cause the most damag

and khalid el bakraoui. the man on the right is faycalc or faycal cheffou. najim laachraoui was identified by dna. laachraoui is the suspected bomb maker. the suicide-bomber in brussels was khalid el bakraoui, who rented the safous, and also rented the hide out in brussels where salah abdeslam fled after the attack in paris. but this man is still being hunted. this may be the third airport bomber. a bomber whose photograph has been all over the belgium media, yet he was arrested here just outside of the federal prosecutors' offices. a place crawling with soldiers and police. 101 casualties are still being treated in hospital. four of those killed in tuesday's bomb attacks have yet to be identified. it's a difficult forensic task. >> you have to understand that a terrorist bomb contains small and large metal pieces, that these hit the victims at a high speed. out of respect for the relatives we won't release further details. >> brussels remains tense, and the interior minister and brussels' mayor urged the postponement of a rally planned for sunday. policing t

bakraoui also died. he had been deported from turkey after being detained at the syrian turkish border last june. he was released due to lack of evidence. his brother khalid el-bakraoui is believed to have carried outlet suicide bombing at the metro. he was also a paris suspect. dominic, what are we expecting to happen today? >> reporter: we were expecting that salah abdeslam, who is being held in the maximum security prison, would make an appearance today at court here in brussels for the start of proceedings against him here. it ourns out that that is not going to happen. we understand that his lawyer appealed for a two-week post opponent and that was granted. we understand that salah abdeslam has, according to his lawyer, refused to coordinate with investigators since tuesday's events which sheds more light on the situation regarding his detention and regarding him clearly. insofar as other things that are happening in brussels today, we know that there will be a meeting of the e.u.'s interior and justice ministers, an emergency meeting clearly called to discuss what has happened here in belgium, in brussels, and to see what can be done about in at the

bakraoui. he had been deported from turkey after being caught at the border last june but was released due to a lack of evidence. his brother, khalid el-bakraoui is believed to carry out the bombing at the station. he was also a paris suspect. one brahim el-bakraoui had been arrested in turkey last year. he was picked up close to the border with syria. the turkish president said he had been deported back to europe and officials there had been warned. >> translation: one of the brussels attackers was caught in gazian gazianteep in june 2014. he was released. despite our warnings that this person is a foreign fighters year, they couldn't establish a terrorism link >>> the man police say is a key suspect salah abdeslam is the subject of a court hearing in brussels. the session will relate to his continued detention. salah abdeslam was born in belgium but has french nationality. he was arrested last week. the authorities have called for his extradition. as far as his legal team is concerned, what is the logic of the rational abouts e behind him staying in belgium and not ending up in france? >> reporter: that is the question that every

the second brother, khalid el bakraoui, came here to carry out his suicide attack, in the shadow of the offices of the european union, making his way through commuters to detonate his explosives. he stepped into this subway car, metal. surviving passengers climbing out into the darkness. hours later, police teams descend on the terrorists' safehouse. forensics investigators in white suits dusting for fingerprints, carrying out evidence. and in a garbage can on the same street, a dramatic discovery -- the discarded computer of airport bomber ibrahim elle bakraoui. and on it, a final, desperate message. the terrorists writing about, quote, being in a rush. no longer knowing what to do, being sought everywhere, no longer being safe. and worrying about spending the rest of his life in a jail cell. so, david, it appears from this message that the attackers believed that the net was tightening around them. that the authorities were closing in, and that they had to act now to pull off these horrific attacks. david? >> alex marquardt leading us off. alex, thank you. and with that discovery, tha

khalid and brahim bakraoui, wrote, twobrothers blew themselves up. they are searching for the third suspect, the guy on the right side. this his the deadliest attack in decades. all night police conducted raids. khalid el bakraoui, according to a tv station, rented an apartment raided by police last week in the operation that led authoritieses to the top paris attack suspect, salah abdeslam. the airport and several brussels metro stations are closedded today, if we want to look at apple tv i can show you the statement from the brussels airport, about the closure of the airport. they say following the attacks, there will be no flights in and out of brussels airport because we have no axles to the access to the building. they talk about folks who may have lost luggage in the chaos yesterday, and what they need to do to get those items back eventually, though it won't be soon. anyone with flightses that are going through the airport in brussels, have been asked to contact their airline because they are not going to get in the there. >> christine: two peo

ibrahim and khalid bakraoui. one blowing himself up after the airport, the other blowing himself up at the subway. officials believe the two individuals also were linked to the paris attacks, they provided a safe house for the paris attacks that took place in november in that country that left 130 people dead. in terms of what is happening here. there is also one key piece of the puzzle that remains unanswered and officials have told nbc news they don't have much leads on it. and that is the third identity of that suspect who is also discovered at scene of the airport explosion. he's believed to be one of the suicide bombers. that individual najim laachraoui is part of the investigation. they have in the past found his finger prints connecting to him events and houses that they raided. a lot of different elements of the i didn't of the individuals. speculation whether there was a second bomber at the subway stwag station. that is not clear according to officials. so i wish i could tell you that the officials here
