WASHINGTON (AP) — At least one person was injured in a shooting Monday morning at a building at the Washington Navy Yard, the U.S. Navy said, as authorities searched for an active shooter.
But a defense official, who spoke to The Associated Press on condition of anonymity because he was not authorized to speak during an active attack, said there were at least several injuries.
The Navy said three shots were fired and that about 3,000 people work in the building. People inside the building were directed to shelter in place. Police and federal agents from multiple law enforcement agencies responded to the scene and streets in the area were closed.
Naval Sea Systems Command is the largest of the Navy's five system commands and accounts for a quarter of the Navy's entire budget. It builds, buys and maintains the Navy's ships and submarines and their combat systems.
