Rep. Mike Thompson (D-Calif.), chairman of the House Gun Violence Prevention Task Force, called on his Congressional colleagues to show "courage" and take a stand against gun violence.

"Ask yourself – how can you claim that you respect human life while choosing fealty to weapons-makers over support for measures favored by the vast majority of your constituents," Murphy wrote.

Witnesses said an armed man walked into the First Baptist Church around 11:30 a.m. and opened fire.

Police have not confirmed the official number of fatalities.

The local news station KSAT reported that the gunman was also killed.

The attack comes more than a month after the nation's deadliest mass shooting in modern history, in which a gunman opened fire on a country music festival in Las Vegas, killing 58 people and injuring hundreds more.

President Trump, who's embarking on a 12-day trip to Asia, tweeted shortly after reports of the shooting surfaced.

"May God be w/ the people of Sutherland Springs, Texas. The FBI & law enforcement are on the scene. I am monitoring the situation from Japan," Trump wrote.
