Their cars on highways. And Birth Control battle. A big fight today that could impact women across the country. Nightly news begins right now. Announcer brussels terror attacks, this is nbc nightly news with lester holt. Reporting tonight from brussels. Good evening. Behind me a scene that has become all too familiar in europes latest wave of terror. This is the plaza in front of the Stock Exchange in central brussels, now a place of remembrance for the victims of yesterdays terror attacks. This region remains on high alert. Investigators made some important headway today identifying a pair of brothers as the suicide bombers and zeroing in on the other attacker who appears to have escaped. And breaking news tonight. Nbc news has just learned those brothers were also directly involved in the paris attacks, too, providing a safe house and weapons. All of this is now portrait of isis next moves. Chief correspondent, Foreign CorrespondentRichard Engel leads us off now with new details. Reporter tonight new information about the men Officials Say were responsible for all of this. Belgian prosecutors identified this man, Ibrahim Bakraoui as a suicide bomber, a u. S. Official said the man standing next to him was najim laachraoui, the bombmaker, who also blew up in the attack. Bakraouis brother, Officials Say, also died in the Suicide Attack on the brussels subway, and right now an urgent manhunt is still under way for at least one more suspect. Now nbc news is learning from u. S. Intelligence officials it all goes right back to the paris attacks four months ago. Brussels was the work of the same cell reborn. It unfolded like this. Back in paris amid the shootings and bombings, one of the attackers, Salam Abdeslam got away and where a senior u. S. Official said abdeslam rebuilt what was left of the cell and started to plan for new atrocities. U. S. Officials tell nbc news that the three suitcase bombs at the airport attack weighed as much as 44 pounds each and belgian authorities today uncovered a huge some pile of explosives the terrorists left behind. What does that say to you about what they found . We found detonators and materiel to produce detonators. We know how they are operated. Reporter Thomas Benard is a terrorism expert who advises the belgian government. The question is, one, whether that factory was used for other operations, for making other bombs that may still be out there, so that is something we need to be very careful with. Reporter this is yet another house police have raided as they follow the evidence trail. We dont know all the details of what they found inside yet, but what is clear is that they are very much playing catchup. Belgian police said Ibrahim Bakraouis last testimony, his will on a computer left in a dumpster. In it he said he felt hunted, no longer safe and didnt want to end up in jail. Nbc news has learned that the bakraoui brothers were deeply involved in the paris attacks. One of the brothers rented the last safe house some of the paris attackers used before carrying out the abeing at all. The other brother helped find them weapons. Lester, back in paris, these two brothers were mostly involved in logistics, but once they came here, they became operational, active attackers. It shows an organization that can adapt and is resilient. And makes people wonder if the threat is really over. Doesnt seem to be. Richard engel, thank you. The people of brussels have shown remarkable courage both during the attacks and in the aftermath of all of this, but questions persist about whether more can be done here to stop this kind of horror from happening. Nbcs bill neely has more on that. Brussels today a minute silence for the dead and then defiance from the living. The applause of a people scarred but not beaten. Their morning commute guarded by troops. All i can do is show im not afraid. Reporter youre not afraid. No, im not. We cannot give into fear. Reporter defiance and patriotism. Youre wearing belgian colors . I think Everybody Needs to wear it now. Reporter but theres disbelief, too, that men from their city would do this and could make their bombs in this building without anyone noticing. So nothing strange . Nothing strange. Reporter but its what the terrorists left behind other thats staggering. Nearly 40 pounds of unused explosives. Nearly 50 gallons of explosive liquid, nails, shrapnel, a suburban arsenal of terror. Their bombs massacred commuters. A triage center. Between 40 and 50 wounded people brought in here into the hotel. Reporter but could it have been stopped . U. S. Counterterrorism officials tell nbc news belgium had warnings of attacks but not enough to disrupt them. They did not raise their terror levels. The Belgian Security forces are not regarded as the best in europe, and i think that this will be another wakeup call. Reporter their police forces, 19 separate ones in brussels alone, failed to stop the terrorists. They are undermanned in immigrant areas from where hundreds of locals left to fight for isis. They are overwhelmed and are now hunting bombers on the run. Its over. I think its over snow hope its over . I hope, of course. Reporter they hope, they hug, they pray and they march. For the airport of remembrance and resolve that the bombers of brussels will not win. The last time belgians faced their capital bombed and troops on the streets was during world war ii. They are resillient, they are tough, but they are tonight asking tough questions of their intelligence services, their police and their government. Lester . All right, bill. That hope that you speak of being echoed behind me here tonight. The state Department Says about a dozen americans were injured in tuesdays attacks and a number of u. S. Citizens remain unaccounted for, including some staffers at the u. S. Embassy here. Today i spoke to one american couple who managed to escape the bomb blasts with their lives. The scene today atch savntm airport, some with a gutwrenching task of identifying those killed in yesterdays explosions. Quick succession around 8 00 a. M. Followed by a third explosion at the metro station. We were counting our bless snoogs arizona couple denies and Andrew Brandt were waiting a connecting flight just on the other side of the terminal that was struck. You felt it . Yeah, felt. It just kind of came through us. It was shock wave that we felt throughout our whole bod is. Reporter did you immediately think terrorism, bomb . We i would say yes. Reporter the explosions injured hundreds, including several americans. A group of mormon missionaries traveling together from utah. 66yearold richard northerny is in a medically induced coma and joseph empey and mason wells, both recovering from shrapnel injuries and seconddegree burns and belgian basketball player Sebastian Belin seen here following the terror attacks suffered serious leg and hip injuries. Department is working to account for other americans as families desperately await word on their loved ones, including new york brother and sister sascha and Alexander Pinczowski on the phone with a relative when the airport blast happened. They havent been heard from since. The brandts say they and hundreds of others were evacuated out of the cold airport tarmac and told virtually nothing. It seemed like forever. A couple of hours maybe, and then one a Flight Attendant got on to one of the planes and opened the emergency door and was just throwing blakeets out to women and children. All those evacuated were told to leave their belongings right where they were in the airport. No one knows when they will be able to fly out of the airport here, but thats a small price to pay for their lives, and they are happy, of course, to be alive tonight and sorrowful for all the victims. Tonight, as state department alerts americans about the risk of traveling to europe, there is noticeably increased u. S. From subway systems to trains, airports and schools. But beefing up security comes with a big challenge. Finding that balance between guarding against terrorism while safeguarding freedom of movement in an open democracy. Nbcs tom costello has details. Reporter at hartsfield airport in atlanta this morning. For some reason they are make us rush out of here and evacuate. Reporter panic as a suspicious package took on a postbrussels urgency. The south termial evacuated. A false alarm as Police Across the country move to a heightened state of alert in airports, subways and train stations. At Union Station in washington Amtrak Police dogs were working the next outbound acela train while a tsa viper team made up of normally Undercover Air marshals watched the crowd inside. Air marshal in charge ray wilder. We want to keep the terrorists off their game,in unpredictable and in places where its best to be there. Reporter security show force is a powerful deterrent, but americans pass through socalled soft terror targets every day, schools, shopping malls and sporting events. The 2013 Boston Marathon bombing, a prime example of a 26mile soft target. Since that day Boston Police have added more than 150 cameras and made terrorism a daily priority. Its all about intelligence. Its all about outreach, and its all about the public stepping up and helping us. Reporter 15 years since 9 11, Homeland Security says its critical the public remains vigilant. Looking out for people who seem to be surveil surveilling a location and gathering information about things like shift changes and testing security with false alarms. An evolving security challenge and an enemy who only needs to get through once. An emerging technology might also help. Eventually the possibility that when somebody pulls up to an airport curbside like this one, facial recognition cameras will capture that face and immediately compare it against the letter, that Technology May be years away. Back to you. All right. Tom costello, thank you. Defended his strategy to take on isis today during his visit to he said defeating these terrorist is his top priority, but 2016 republican candidates accuse him of not doing enough to combat the threat with terrorism now dominating this campaign again. We get more from nbcs andrea mitchell. Reporter president called isis vicious killers but not a threat to the u. S. They cant defeat us. They dont produce anything. They are not an existential threat to us. Reporter republicans immediately attacked. Terrorism, a leading campaign wedge issue. After paris, after san bernardino, a majority of Republican Voters citing terrorism as their number one concern. Now after brussels donald trump renewing his call to ban muslims and torture terror suspects and ted cruz calling for surveillance of muslim neighborhoods in the taking that on a day after leaving cuba. I just left a country that engages in that kind of neighborhood surveillance which, by the way, the father of senator cruz escaped for america. Reporter cruz lashing back. And we have seen president obamas weakness and apiece meant give rise to radical islamic terrorism. Reporter to the campaign oneliners match the challenge. Well bring them to jut tis, you know. Well fight them over there so that we dont have to fight them over here. That is not how the world operates. Reporter Hillary Clinton trying to portray herself as the grownup in the room. When republican candidates like ted cruz call for treating american muslims like criminals its wrong, its counterproductive, its dangerous. Reporter the president under fire on a Critical National security issue and the two parties sharply divided. Lester . Andrea, thank you. Brussels arent the only thing making news on the campaign trail. Personal attacks between donald trump and ted cruz have reached a new level with their wives now getting dragged into their nasty rivalry. Heres nbcs hallie jackson. Reporter this racy antitrump ad meant to turn off utah mormons now turning attention to the tone of the gop race. Meet milania trump, it says, your next first lady, or you could support ted cruz on tuesday. That ad was completely inappropriate, and we had nothing to do with it. Reporter image was created by an outside stop trump group but that didnt stop trump himself from threatening cruz, hed quote, spill the beans about wife heidi. Still not clear what trump is talking about. There are a lot of things that donald trump and his campaign say that have no basis in reality. Reporter cruz tweeting back with the classless. So agitated he tiptd message himself, the campaign says. Hes better sticking with me out of his league. Reporter trump accusing cruz of lifting lines. You better stick with me because Sidney Allen Wade is way out of your league. Reporter entire episode rage the question is anything off limits anymore . I think its always nasty but this year its extraordinarily nasty. Reporter liz mayer created the digital ad featuring the former model in british gq. I think donald trump has obliterated all conceivable lines in this campaign and im perfectly comfortable with what weve done. For cruz theres some lines thunt cross. We shouldnt attack each others spouses and children and thats gutter politics. Reporter hoping to set rules in a race that doesnt seem to have any. Hallie jackson, nbc news, new york.

President obamas Health Care Plan backed today at the supreme court. Groups that object on religious grounds say they should not have to provide contraceptive coverage for their employees, and as our justice correspondent Pete Williams reports, without Justice Scalia this one could be headed for a 44 tie. Reporter Little Sisters of the poor, catholic nuns who care forth elderly, shay they should be exempt from obamacares requirement of providing Employee Coverage for couldnt [c raceptives contraceptives. The government says they can opt out if they provide notice that they object on religious grounds and turn over information about their insurance, but the nuns and dozens of other religiously affiliated charities, seminaries and colleges are suing. They are saying having to do that is even too much. The services will still become a part of our health plan hand thats just something that we cant agree to. Reporter while groups on both sides staged spirited demonstrations outside the court. Inside the four remaining conservatives seem to agree with the nuns. Chief Justice John Roberts said the government wants to hijack their Health Care Plan. Justice Anthony Kennedy used that same word, hijack. We welcome you into our nation. Reporter the Obama Administration says a groups religious freedom does not include the right to restrict access to health care for ploys and even for students at religiously affiliated colleges. Students, faculty to contraception. Its not some sort of third class or second Class Health CareReporter Court seemed split 44. A tie would leave in place the decision among the lower courts. That would be bad for the Little Sisters who lost in the Appeals Court and it means that women who work for religiously affiliated organizations would get the contraceptions in some states but not the others.
