Two people, including the gunman, have been killed in a shooting at a church in Texas.
A third person has been taken to hospital in a critical condition, according to local police.
The gunman was killed by two armed parishioners, police chief J.P. Bevering said.
The shooting took place at the West Freeway Church of Christ near Fort Worth, Texas, on Sunday morning.
All of the victims are believed to be male.
Authorities have not released any details about what led to the shooting.
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.
Mike Tinius said: ‘He was trying to do what he needed to do to protect the rest of us.
‘It’s extremely upsetting to see anyone committing violence.’
Tinius said he didn’t know the gunman and that the shooting appeared to be random.
WFAA, a Dallas-based TV station, reported that the church live-streamed the service on YouTube and that the video showed a man wearing a long coat produce a rifle or a shotgun which he fired twice before someone shot back.
Some members of the congregation ducked behind pews while others with handguns rushed the gunman, WFAA said.
Church members can be heard screaming and crying.
In an interview with Dallas TV station KTVT, Mike Drivdahl, the spokesman for the Fort Worth Fire Department, said he believes the gunman was among the three who were shot.
Governor Greg Abbott asked the state to pray for the victims and their loved ones.
In a tweeted statement, Mr Abbott said: ‘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.’
It is not the first deadly shooting to take place at a church in Texas.
In November 2017, Devin Patrick Kelley opened fire on the congregation at a church in Sutherland Springs, Texas, killing more than two dozen worshippers, before taking his own life.
