When i went into the office, they told me to go home. Because, because of the attacks and because of the location of our office building. There are always armed guards out front but they just werent sure what was going on and they figured it was safer for us to be out of the building than to go home. I got on to the tram line to go home. But they shut it down partway and luckily one of my friends in my study abroad group, sam. She took me in.

And among them, the weapons that were used by the attackers in both the airport and metro. It appears that the terrorists used nbcs justice correspondent Pete Williams explains. One circle that were trying to square here is the dispute between what isis is claiming and what authorities are teing us. The claim from isis says that these were attackers wearing explosive belts is the way they put it. Not suicide vests, thats the term they used. Nonetheless, several officials have told nbc news that they believe the bombs at both the airport and in the subway train were in suitcases. Some estimates are that the suitcases may have contained at least 2040 pounds of explosives, just a rough guess. Two of the suitcases were detonated they believe in the airport. A third super kaitcase did not. We saw the picture earlier of the suspects th brussels, they were pushing what looked like luggage carts, one thing that authorities are looking at is whether those in fact were the very suitcases that contained the bombs that they were carrying or pushing along on those carts. In any event, despite whether they were actually on the carts or not, authorities tell us several different sources, that they believe that the explosives were in suitcases, not suicide vests. The brussels attack comes in the middle of a spirited Political Campaign in this country. The president ial candidates weighed in on what they would do to prevent future attacks. Republican frontrunner donald trump says it starts with keeping terrorists out of the country. I would exclude the people coming in from syria that dont have documentation coming in from the migration line. Frankly, the waterboarding if it was up to me, the waterboarding would be fine and if they could expand the laws, i would do a lot more than democratic candidate Hillary Clinton agreed that security does need to be tightened. But she says closing the borders is not the answer. We have to do a much better job in coordination with the europeans on tracking and following anyone who has any connection with terrorist activity or terrorism. We need to forge a coalition of the muslim countries in the region. With the support of the United States and other major powers to finally destroy this barbaric organization.
