At Least 12 People Killed in Shooting at Navy Building in Washington

At least 12 people have been killed at a Navy building in Washington by a gunman who was later killed but may not have acted alone, authorities said.

D.C. Police Chief Cathy Lanier told reporters that 12 people died in the 8:20 a.m. incident at the Naval Sea Systems Command headquarters in southeast Washington. There were conflicting reports on the number of victims and the number of gunmen in the ensuing hours, although a federal law enforcement official told Fox News that one shooter has died. Police said as many as two additional gunmen may still be at large, and thousands of workers who report to the building were being told to “shelter in place” until officials could safely evacuate them.

“This is not over,” Rear Admiral John Kirby, the U.S. Navy’s chief spokesman, told reporters. “The building is still in lockdown, as are other buildings. Still being treated as an active search. No one is moving right now.”

People who were inside the building said a gunman wordlessly sprayed fire from an AR-15 assault rifle as terrified civilians and Navy members scattered.

More than 20 members of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) responded to the scene, including the same Special Response Team that extracted the alleged Boston Marathon bomber Dzhokhar Tsarnaev from the boat where he barricaded himself following the April 15 attack.
