A US airman is believed to have shot his commander in an apparent murder-suicide at an air force base in Texas.
Brigadier General Robert LaBrutta, who oversees Joint Base San Antonio-Lackland , said two handguns were found near the bodies of the men.
He stressed that the shooting was not an act of terrorism.
He declined to identify the two men, saying their families must be notified first. The FBI is leading the investigation.
Bexar County Sheriff's spokesman James Keith said earlier that officers had responded to reports of an active shooter at the base which is the home of US Air Force basic training.
Mr Keith said two bodies were found inside a room in a building at the base, and it was believed the shooter was among the two dead.
