() Multiple people were shot Friday at a business in Anaconda, Montana, according to the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

“I’m closely monitoring the situation involving an active shooter in Anaconda. Please join Susan and me in praying for the victims, their loved ones, and the brave law enforcement officers responding to this tragedy,” Montana Gov. Greg Gianforte said in a statement posted to social media.

Officials warned people to avoid the area of Anaconda. The suspect’s home was cleared by a SWAT team and the suspect was still at large, the Granite County Sheriff’s office said in a social media post.

Authorities have yet to release details about what led to the shooting or the conditions of those who were injured.

Sandra Barker, a spokesperson for the FBI’s Salt Lake City office, which covers Montana, said the FBI is assisting in the response to the shooting but referred questions about it to local authorities.

This is a developing story.
