Washington, DC - At 12:03 p.m. the all clear was given at the Washington Navy yard after a 7:29 a.m. call was placed from a building inside the yard to report possible gun shots. Navy Yard officials called partner law enforcement agencies for assistance.

NCIS agents and other law enforcement have completed their inspection of the Humphreys Building (Bldg. 197). All personnel are safe and accounted for.

There are no signs of a shooting, a shooter, or victims.

"All our commands practice active-shooter drills...no doubt in my mind that made a difference this morning," said Vice Adm. Dixon Smith, commander, Navy Instillations Command, at a joint press conference at the Navy Yard Thursday morning.

The Washington Navy Yard and law enforcement agencies have trained to respond to this type of situation. This resulted in an organized search of the facilities by first responders.
