According to various wire and news reports, at least 12 people were killed in a shooting on Monday at the U.S. Navy Yard in Washington, where a suspected gunman was reportedly among the dead and authorities were searching for two other possible assailants wearing military-style clothing, officials said.
The exact number of dead and wounded fluctuated in the hours following the shooting, which took place about three miles from the White House, starting about 8:30 a.m. EDT (1230 GMT).
The Washington D.C. mayor and the police chief said there were 12 fatalities in the shooting at the Naval Sea Systems Command, one of five such commands where civilians, military personnel and contractors build, buys and maintain Navy ships and submarines. About 3,000 people work there.
