“It was very surreal,” John Schlicher, a witness, said. “He did not say a word.” He described the shooter as a slender man with dark hair, likely in his 30s, wearing a Star Wars T-shirt.
Schlicher said he heard crews ordering passengers to take cover. He spoke over the phone while ducked down on the floor.
“He was shooting people that were down on the ground, too,” Schlicher said.
The gunman apparently got down on the ground and waited for police to arrive after he ran out of bullets, a witness said.
The airport had tweeted that there was an “ongoing incident” at the Terminal 2 baggage claim and that all services were temporarily suspended. The terminal serves Delta Air Lines and Air Canada.
Crews evacuated hundreds of passengers from the terminal onto the tarmac.
Ari Fleischer, a former White House spokesman, was at the airport at the time of the shooting and tweeted that “everyone is running.”
Jillian Saunders, from Palm Beach, Florida, told The Associated Press in direct Twitter messages that she was watching the activity from the tarmac in a plane scheduled to fly to Los Angeles.
“Everything you see on the news is happening outside my window,” she said. “I am luckily on the plane and they said we are right now the safest people at the airport.”
The office of Florida Gov. Rick Scott said state law enforcement have not confirmed a motive behind the shooting. Scott is traveling to the scene to be briefed by law enforcement.
The ATF was responding to the scene. Homeland Security Secretary Jeh Johnson was monitoring the shooting and getting regular updates — part of standard practice, a federal law enforcement source told Fox News.
The airport is the 21st busiest in the United States and serves 21 different airlines. Nearly 2.5 million people passed through the airport in November, according to a county government report.
