At least 26 people have been killed and 20 others wounded after a gunman opened fire at a Texas church during Sunday service.

The attack happened at the First Baptist Church in Sutherland Springs, a small town in Wilson County. The victims' ages ranged from five to 72.

The suspected gunman was later found dead in his vehicle some miles away.

Police identified him only as a "young, white male", but US media named him as Devin Patrick Kelley, 26.
