FORT LAUDERDALE -  A county official says the Fort Lauderdale airport shooter pulled a gun out of a checked bag, loaded in a bathroom and started shooting, killing five people and wounding at least eight.

Chip LaMarca, a Broward County commissioner, was briefed on the airport shooting by Broward Sheriff's office. He told The Associated Press by phone that the shooter was a passenger on a Canadian flight and had checked a gun.

LaMarca says the shooter pulled out the gun in the bathroom after claiming his bag.

Sheriff Scott Israel says the gunman was not harmed and that law enforcement did not fire any shots. He says it is not yet known if the shooting was an act of terror.

Israel also says there was nothing to substantiate reports of a second shooting at the airport.

News stations showed video of medics taking care of a bleeding victim outside the airport. Helicopters hovering over the scene showed hundreds of people standing on the tarmac as an ambulance drove by and numerous law enforcement officers, including tactical units, rushed to the scene.

Former White House spokesman Ari Fleischer tweeted that he was at the airport when shots were fired and "everyone is running."

U.S. Sen. Bill Nelson says the Fort Lauderdale airport gunman was carrying a military ID with the name Esteban Santiago, though it's not clear if it belonged to him or to someone else.

Nelson did not spell the name for reporters during a news conference Friday. Nelson says the baggage claim area is a "soft target." The airport had initially reported an "incident" in the baggage claim area.

Nelson says a motive still hasn't been determined.
