At least two people have been killed and one more is in critical condition after a shooter opened fire in a Texas church Sunday morning, according to reports.

The Dallas Morning News reported that the entire incident was initially broadcast on a live stream of the service at West Freeway Church of Christ in White Settlement, Texas. The video — which has since been taken down — showed one person standing up just as communion ended, removing a long gun from his coat, and firing twice before at least one person shot back.

Local ABC News affiliate WFAA reported:

The entire shooting lasted about six seconds, video of the live stream shows. Many people in the congregation ducked under church pews while others rushed toward the shooter, holding up handguns, the video shows.

One church leader stood up, saying, “Everything is under control. Our security team did everything they needed to do.” (RELATED: Gunman Kills 26 People In Mass Shooting At Texas Church [VIDEO])
