A terminal at John F. Kennedy International Airport in New York City has reopened more than two hours after being evacuated Sunday evening because of a bomb scare that turned out to be a false alarm.

A Port Authority of New York and New Jersey spokesman told CNN that at about 5:40 p.m. ET an anonymous woman called in a bomb threat to Terminal 1, and that just before that an airport employee noticed an unclaimed bag in the terminal.

As a precaution, 250 to 300 passengers were ordered to leave the Terminal 1 at about 6 p.m., spokesman John Kelly said.

He said police checked the bag and it was not a bomb. Passengers were allowed back into the terminal after 8 p.m.
