A gunman shot up to 12 people, including two police officers, on Monday at a Navy facility in Washington, authorities said. Naval officials said that the gunman was on the loose.
NBC News' Jim Miklaszewski reported up to four people were dead.
SWAT officers swarmed the facility, the headquarters of the Naval Sea Systems Command at the Washington Navy Yard.
A naval security guard was among those shot and was hit in both legs, U.S. military officials said. Washington city police told WRC, the NBC affiliate in Washington, that one of their officers was also among those shot. It was not clear how many of the victims were civilian and how many were military.
Tim Hogan, a spokesman for Rep. Steven Horsford of Nevada, posted photos to his Twitter account of people tending to at least one person down on a street corner.
The Navy said on its Twitter feed that three shots were fired at 8:20 a.m. ET at the Sea Systems Command headquarters. Almost an hour later, the Navy still characterized the shooter as “active.” The military officials said that the gunman may have been armed with an AR-15, a military-style assault rifle.
Flights were grounded at Reagan National Airport, WRC reported, and Capitol police said they were stepping up security on the Capitol grounds. Washington police told WRC that nearby schools were locked down, and some bridges were closed.
About 3,000 people work in the Navy building, the Navy said. They were ordered to stay in place. The Naval Sea Systems Command builds, buys and maintains ships and submarines and their combat systems.
The Navy Yard is along the Anacostia River in Washington, near the headquarters of the Department of Transportation and the Washington Nationals baseball stadium.
