A soldier shot dead three colleagues and injured 16 others at the US Army's Fort Hood base in Texas before killing himself, the military has said.
US media named the suspect as Ivan Lopez, 34, although his identity has not been officially confirmed.
The wife of one soldier explained how her husband was "on post" when the shooting happened. She had to await news of his welfare, while in a makeshift emergency shelter.
