Authorities were responding to a "multi-patient incident" at the Los Angeles International Airport on Friday and California media reported that a gunman with a high-powered rifle was shot by law enforcement.
The airport said on social media that there was "an incident underway at LAX." A local CBS affiliate reported that a gunman had been shot and secured by law enforcement, and that some passengers were being evacuated from a terminal.
Passenger Robert Perez told the CBS affiliate that airport security agents had come through the terminal shouting that a man had a gun.
"I heard popping and everybody dropped to the ground," Perez said.
The Los Angeles Fire Department described the situation as a "multi-patient incident," and said it was assisting law enforcement at the scene, according to its website.
Television images on cable network CNN showed at least one person being loaded into one of several ambulances at the scene, and passengers were seen being evacuated from the area.
Footage showed emergency responders setting up what appeared to be a triage area outside an airport terminal.
Airport police and airport officials would not offer any additional information.
