Four people are dead, including the gunman, and 14 others are hurt in a shooting at Fort Hood. The post has been locked down and everyone ordered to shelter in place.
CNN reports that the gunman is dead.
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.
