According to the Associated Press, authorities say they are now looking for two additional suspects in the Washington Navy Yard Shooting in Washington D.C.
District of Columbia Police Chief Cathy Lanier says witnesses reported seeing two additional gunmen, both dressed in military-style clothing.
Lanier says one police officer was wounded in an exchange of gunfire with a shooter. She says one shooter has been killed.
Two Navy officials say at least six people were killed in the rampage.
D.C. Mayor Vincent Gray said at a Monday news conference four people were wounded and taken to hospitals.
UPDATE: The Defense Department says several people have been killed and as many as 10 have been wounded in a shooting at the Washington Navy Yard. NBC News' Pete Williams reports four people have been killed, among them, a D.C. Police Officer. Another person killed was a base security officer.
An official with the Defense Department, speaking on anonymity, also said the shooter is "contained" but not yet in custody.
Earlier in the day, the U.S. Navy said it was searching for an active shooter at the Naval Sea Systems Command headquarters, where about 3,000 people work.
The exact number of people killed and the conditions of those wounded was not immediately known.
