WASHINGTON, (UPI) — Two gunmen opened fire Monday inside the U.S. Navy Yard in Washington, causing multiple deaths and injuries, police said.
The Washington Post said at least four people were killed and eight others were injured in the rampage.
There are believed to be two gunmen. The Post said one suspect was “down” and the other shooter was hiding in one of the buildings inside the complex in southeast Washington. ABC News said it appears one of the gunmen is dead.
Metropolitan Police said a Washington police officer and a base security guard were among the injured.
Gunfire rang out at 8:20 a.m. inside the headquarters for Naval Sea Systems Command.
The U.S. Navy said on Twitter a “shelter in place” order was issued for Navy Yard personnel.
Officials said the shots were fired at the Naval Sea Systems Command Headquarters building where about 3,000 people work.
Police closed the 11th Street Bridge and M Street SE between 2nd and 4th streets SE because of the shooting. Entrances to the Navy Yard Metro station were open.
U.S. Capitol Police said they increased security at the Capitol but indicated there was no immediate threat.
A school near the Navy Yard was on lockdown, the Post reported.
One employee, who declined to be identified, told the Post he heard “blam, blam” inside one of the buildings, then someone pulled the fire alarm.
“We aren’t going back on base today,” he said. “[But] there are still people inside.”
