At least 12 people have died in the shootings at the Washington Navy Yard., D.C. police confirm.
D.C. Police Chief Cathy Lanier told media during a presser that 12 people were confirmed dead.
Lanier said D.C. residents need to stay in their homes and remain out of the area as law enforcement proceed with an intensive manhunt for two other possible suspects.
One of the shooters is confirmed by police as dead.
The police chief said officers are searching for two other possible suspects armed with deadly firearms and wearing military-style uniforms.
Chief Lanier there is no indication of a possible motive at this time.
AP reported that the attack unfolded just a short distance from the White House and the U.S. Capitol at a former shipyard that remains one of the Navy's oldest shore facilities.
The building that was targeted was the military's headquarters for Naval Sea Systems Command. An estimated 3,000 people work at the HQ, many civilians.
The FBI is now taking the lead in the manhunt, Chief Lanier said.

Alexis is believed to have gotten into the Navy Yard by using someone else's identification card. Cops are calling him a lone gunman.
