LOS ANGELES (AP) - Flights are back to normal at Los Angeles International Airport after a plastic bottle containing dry ice exploded in an employee bathroom.
The Sunday evening explosion caused a commotion in LAX's terminal 2 and delays of up to four flights after airport police halted security screening.
No injuries were reported.
FBI spokeswoman Laura Eimiller says the bathroom was in an area of the terminal that was not accessible to the public.
Investigators are trying to determine how the bottle wound up in the bathroom.
