A U.S. law enforcement official says the suspected gunman at the Fort Hood Army base in Texas is now believed to be dead.
Fort Hood confirmed the shooting on the base in a brief statement Wednesday evening. The statement also said emergency crews were on the scene and that further details were not yet known.
The official says reports circulating within the Justice Department indicate the shooter has died of what appears to be a self-inflicted wound. The official spoke on the condition of anonymity because the investigation is still ongoing.
The identity of the shooter and the number of victims were not immediately known.
Bell County Sheriff's Office Lt. Donnie Adams says the sheriff's office dispatched deputies and troopers from the Texas Department of Public Safety to the nearby Texas Army base.
Fort Hood ordered everyone at the base to "shelter in place." The order was sent Wednesday on the base's Twitter feed and posted on its Facebook page.
The 1st Calvary Division, which is based at Fort Hood, sent a Twitter alert telling people on base to close doors and stay away from windows.
A spokeswoman for the base declined to comment.
The base was the scene of a mass shooting in 2009. Thirteen people were killed and more than 30 wounded.
