ANTIOCH, Tenn. – A Tennessee church shooting has left one dead and several others wounded.

Authorities said a woman was killed and seven others sustained gunshot wounds after a 26-year-old black man wearing a ski mask opened fire at a Tennessee church Sunday, reported Fox News. The shooter was among those wounded.

The gunman opened fire at Burnette Chapel Church of Christ in Antioch, southeast of Nashville, just after 11 a.m. and fired “multiple rounds,” police said in a news conference. Moreover, officials said the man shot himself and was taken to a hospital

The Nashville Fire Department called the incident “a mass casualty situation.”

A church usher confronted the gunman at one point and was pistol-whipped, causing “significant injury around his head.” He told police he then went to his own car, grabbed a pistol and headed back into the church. The gunman then shot himself, although details are scarce.

A woman who was fatally shot had just left church. She was walking to her car when struck by gunfire, police said.

The gunman, with his car still running in the parking lot, then entered the rear of the church and shot six people who were eventually rushed to the hospital, according to police. Of the injured, three are women and three are men.

The gunman as well as five victims were being treated for gunshot wounds at Vanderbilt University Medical Center. Another victim and the man who was pistol-whipped were taken to Skyline Medical Center for treatment.

The suspect is expected to survive. Therefore, he remains under police control at the hospital.

“This is a mass casualty situation. All of the wounded have been transported to area hospitals. The majority are older adults,” Nashville Fire Department wrote on Twitter, who later clarified all but one victim was over the age of 60.

However, at the present time, none of the victims or suspect have been identified.

Several witnesses claimed the shooter was wearing a “clown mask” when he opened fire. Yet regardless of these reports, police said he was wearing a mask that resembled more of a ski mask.

The FBI is responding to the incident, but is not leading the investigation at this point.

Megan Barry, mayor of Metropolitan Nashville and Davidson County, issued a statement that the shooting “is a terrible tragedy for our city. My heart aches for the family and friends of the deceased as well as for the wounded victims and their loved ones.”

The church has a weekly service starting at 10 a.m. Sunday. The area surrounding the church was closed off as police investigated the crimes.
