UPDATE from Washington Times:
D.C. Police Chief Cathy Lanier said one shooter was confirmed killed at the scene of the Navy Yard rampage and authorities are looking for two other men who may also have been involved in the attack.
The two at large suspects were dressed in military garb but are not believed to be U.S. service personnel, Lanier said.
One was a young white man in a khaki like uniform and the other was a black man in his 50s with a long rifle in an olive colored garb, she said.
Lanier said there were multiple fatalities at the scene but exact numbers were not immediately.
A Navy spokesman says four have been killed, eight wounded in shooting at the Washington Navy Yard.
