Terminal B evacuated
Authorities told passengers to leave Terminal B as they investigated a car that was left unattended with its doors open, several media outlets reported.

Military personnel at the airport
Several passengers tweeted photos of military personnel standing guard and walking through the airport. Photos also showed passengers standing or walking outside the terminal.

“Just landed at LGA and entire arrivals have been closed and there are soldiers with AR-15s everywhere,” Dan Chen tweeted.

Airport officials and police were not immediately available for comment.

The incident comes less than a week after a series of bombings in New York and New Jersey left 31 people injured in what authorities described as a “terrorist act.”

Ahmad Khan Rahami, 28, was arrested on Monday after being wounded in a gunfight with police in New Jersey and was charged with the bombings.
