LOS ANGELES: The busy terminal of the Los Angeles airport was closed on Sunday night due to a false alarm of gunfire. Unconfirmed reports caused the management to evacuate the passengers for safety measures.

“Upper/Departures & Lower/Arrivals levels of Central Terminal Area (CTA) closed. Please check w/ airlines if heading to LAX,” airport authorities wrote, adding that they were “working to confirm reports” of the shooting.

Right after the reports the Airport Police searched the site and asked the passengers to “remain calm” in a Twitter message.

“All precautions being taken to ensure safety of public,” airport police wrote.

At least two terminals were “self-evacuated” and security personnel were checking them for anything suspicious, according to Officer Alicia Hernandez of the LAX police.

She said terminals would reopen to passengers once they were deemed safe.

U.S. airport security officials have been on an elevated alert situation in the recent months because of the recent severe attacks at International airports in Belgium and Turkey.

The Los Angeles airport, known as LAX, is the seventh busiest airport in the world in terms of traffic. Los Angeles is the second most populous city of the United States of America.
