Police say at least 12 people have died in the shootings at the Washington Navy Yard.
D.C. Police Chief Cathy Lanier said during a news conference Monday that 12 people were confirmed dead.
Lanier says people are being told to stay in their homes and out of the area as authorities search for two other possible suspects. One of the shooters has died.
The police chief says officers are searching for two other people with firearms wearing military-style uniforms.
She says there is no indication of a possible motive at this time.
As many as three gunmen opened fire Monday inside one of the Navy’s oldest buildings, attacking office workers at a heavily guarded military facility in the heart of the nation’s capital. At least six people were killed.
One of the gunmen was dead, and police were searching for two other men believed to have joined in the attack at the Washington Navy Yard. The suspects were reportedly dressed in military-style clothing, including one who had on a beret.
In all, more than a dozen people were shot, at least half of them fatally. It was not immediately clear whether that number included the dead gunman.
The attack unfolded just a short distance from the White House and the U.S. Capitol at a former shipyard that is one of the Navy’s oldest shore facilities.
The building that was targeted was the military’s headquarters for Naval Sea Systems Command, which buys, builds and maintains ships, submarines and combat systems. About 3,000 people work at the headquarters, many of them civilians.
Witnesses described a gunman opening fire from a fourth-floor overlook, aiming down on people in the first-floor cafeteria. Others said a gunman fired at them in a third-floor hallway.
It was not clear whether the witnesses on different floors were describing the same gunman.
