Reports of gunfire at LA airport were false alarm - Police

Terminals at Los Angeles International Airport were evacuated briefly late on Sunday before police determined that reports of gunfire in one of the terminals were only "loud noises".

Footage from the airport shows dozens of people gathered on tarmac and outside terminals at one of the nation's busiest airports.

Police say an investigation is still underway.

U.S. airport security officials have been on heightened alert in recent months following deadly attacks at international airports in Belgium and Turkey.

The alert at LAX comes two months after police temporarily evacuated a terminal at New York City's John F. Kennedy International Airport while they investigated reports of gunfire.

A preliminary investigation of that incident, which also occurred on a Sunday evening, found no evidence of suspicious activity.
