At least one victim was killed and four others were injured when a gunman opened fire inside a crowded Texas church on Sunday morning before he was shot to death by an armed security guard, officials told ABC News.

The shooting occurred at 10:57 a.m. at the West Freeway Church of Christ in the Fort Worth suburb of White Settlement and was captured on the church’s livestream of the service, officials said.

The federal Bureau of Alcohol, Tobacco, Firearms and Explosives tweeted that they had a team “en route to a reported shooting at the West Freeway Church of Christ in White Settlement, Texas.”

Three people were taken to hospitals, including one who remained in critical condition. Another victim died en route to the hospital, officials said.

The shooter, whose name was not immediately released, was pronounced dead at the scene, according to a spokeswoman at MedStar Hospital in Fort Worth.

Two other people suffered minor injuries when they hit their heads attempting to flee the church, officials said.

“Out hearts go out to the victims and families of those killed in the evil act of violence that occurred at the West Freeway Church of Christ,” Texas Gov. Greg Abbott said in a statement. “Places of worship are meant to be sacred, and I am grateful for the church members who acted quickly to take down the shooter and help prevent further loss of life. ”
