SUTHERLAND SPRINGS, Texas -- A gunman opened fire inside the First Baptist Church in Sutherland Springs Sunday, killing and injuring multiple people, authorities said.
At least 15 people were shot, a law enforcement official told CBS News' senior investigative producer Pat Milton. That number is expected to be higher, and of those 15 people shot, it's unclear how many were fatalities.
Wilson County Sheriff Joe Tackitt told the Wilson County News that a man entered the church and opened fire. He said there were multiple casualties and fatalities. CBS affiliate KENS confirmed at the scene that there have been "multiple casualties and fatalities" including children.
The Connally Memorial Medical Center told CBS News it received multiple victims related to the shooting.
A law enforcement official confirmed the gunman is deceased. He was shot after a car chase with police. It's unclear if he shot himself or if he was shot by police, Milton reports.
Video from KENS showed first responders at the scene, located about 30 miles southeast of San Antonio.
Dana Fletcher, a business owner in the area, told CBS News she saw a "ton" of sheriff's vehicles and ambulances racing down the road. She said she doesn't know what happened but said there was heavy police presence and people were being airlifted from the scene.
Special agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives said they were responding to the shooting.
A law enforcement official said an FBI crisis response team is on scene to offer assistance to local police, CBS News' Milton reports.
The FBI will be offering evidence recovery, offering to check through databases to see whether this person has any connections to international terror to see if its a terrorist event or a domestic situation, Milton reports. She says officials looking into it but they don't know the motivation at this point.
President Trump said on Twitter that he is monitoring the situation from Japan.
"May God be w/ the people of Sutherland Springs, Texas. The FBI & law enforcement are on the scene. I am monitoring the situation from Japan," Mr. Trump tweeted Sunday.
Texas Gov. Greg Abbott tweeted his condolences to those affected in the incident.
