UPDATE: 2 LSU students in Brussels on exchange trip, both are "safe"
BRUSSELS- Three explosions ripped through the Brussels airport and subway station Tuesday during the morning rush hour.
A spokesman for the city's transit system says at least 31 people were killed and another 150 people were injured in the third explosion, which happened at a busy subway station in the city.
Two LSU students are currently in Brussels for an exchange trip, according to LSU's media relations director Ernie Ballard. Ballard said that both students have "checked in and are safe" since the explosions.
Belgian federal prosecutor Frederic Van Leeuw is calling all three of the explosions "terrorist attacks."
One traveler, Zach Mouzoun, who arrived on a flight from Geneva about 10 minutes before the first blast at the Brussels airport, told France's BFM television that the second louder explosion brought down ceilings and ruptured pipes.
"It was atrocious. The ceilings collapsed," he said. "There was blood everywhere, injured people, bags everywhere."
Shortly after the airport explosions, reports of a third blast along the subway line started coming in.
Authorities are telling everyone in Brussels to remain where they are.
The explosions happened only days after the prime suspect in the Paris attacks, Salah Abdeslam, was arrested in Brussels.
Tuesday morning, the president said the United States will do 'whatever is necessary' to bring Belgium attackers to justice. WBRZ.com streamed the remarks live. The live event has concluded.
