Donald Trump has stated his belief of how the shooting in Texas was the result of a "mental health problem", rather than US gun laws.
At least 26 people were killed after a gunman opened fire on worshippers in Sutherland Springs' First Baptist Church, located just outside of San Antonio.
The suspected gunman - who has been identified as Devin Patrick Kelley in US media reports - was later found dead of a gunshot wound several miles away from the scene of the shooting.
In response to the massacre, the US President - who is on a formal tour of Japan - gave a press conference to respond to the attack, having previously called it an "act of evil."
When asked by a journalist present, Trump stated his belief the incident was a "mental health problem at the highest level", quoting preliminary reports about the mindset of the shooter.
He made it clear he does not believe there was a problem with US gun laws.
The Second Amendment of the American Constitution allows US citizens the right to bear and keep arms, which has proven to be a key obstacle for lobbyists seeking to change US gun laws.
