WASHINGTON (AP) — Gunshots were fired Tuesday morning near the entrance of the Pentagon, resulting in multiple injuries. The facility, the headquarters of the U.S. military, was placed on lockdown. The Arlington County Fire Department reported “multiple patients,” but it wasn’t immediately clear if they had been shot or the extent of the injuries. The incident occurred on a Metro bus platform that is part of the Pentagon Transit Center, the Pentagon Protection Force Protection Agency tweeted. The facility is just steps from the Pentagon building. The agency responsible for security at the building, the Pentagon Force Protection Agency, tweeted that the scene of the incident was secure, though there was no announcement that the lockdown had been lifted.
