Two men were killed and another man was injured in a shooting at a church in Texas on Sunday — the latest in a string of attacks at houses of worship in recent years.

Sunday’s shooting unfolded around 9:57 a.m. at the West Freeway Church of Christ, which is located in the city of White Settlement, just outside of Fort Worth.

A spokeswoman for MedStar Mobile Healthcare, an ambulance service, told The Associated Press that two people had been shot and killed, one of them the gunman; a third person, in critical condition, suffered cardiac arrest but was revived.

An elder at the church told the New York Times that one of those killed was a security guard who responded to the shooter, calling him a dear friend. “He was trying to do what he needed to do to protect the rest of us,” Mike Tinius said.
