A gunman opened fire at a Texas church on Sunday during a service, killing at least 26 people and injuring another 20.
The attack occurred in the small town of Sutherland Springs in Wilson County. The victims are reportedly aged between five and 72.
The suspected gunman has been identified by media in the United States as Devin Patrick Kelley, 26. He was found dead in his vehicle a few miles away from the scene.
The motive behind the mass murders is currently unknown.
In 2014, Kelley is said to have been discharged from the US Air Force for assaulting his wife and child.
According to the Texas Department of Public Safety regional director Freeman Martin, the suspect was dressed in all black and wore a bulletproof vest, used an assault-style rifle and opened fire from outside the church and then later went inside.
A local citizen began shooting the suspect as he left the church, later fleeing in a vehicle.
The suspect was later found dead in his vehicle but it is unclear whether he died from self-inflicted injuries or from the shots fired by the citizen.
Several weapons were found in his vehicle.
23 people were found dead inside the church, two outside, while one is said to have died in hospital.
During a press conference on Sunday, Governor Greg Abbott said this is the worst mass shooting in the history of Texas.
