Multiple firefighters in Idaho were fired upon while responding to a blaze in Coeur d’Alene on Sunday, while the gunman remains at large, according to the governor and local authorities.

The governor, Brad Little, on social media called the attack “a heinous direct assault on our brave firefighters.” He said they were responding to a fire, though he did not specify where.

“As this situation is still developing, please stay clear from the area to allow law enforcement and firefighters to do their jobs,” he said.

The Shoshone County Sheriff’s Office asked residents on Facebook to avoid Coeur d’Alene.

The post said that “we are dealing with an active shooter situation where the shooter is still at large” and asked residents not to call the office for more information.

Kootenai County Emergency Management told residents to shelter in place and avoid the area near Canfield Mountain Trailhead and Nettleton Gulch Road.

The office expanded the alert to include an area south of Hayden Lake Road and east of 15th Street.

It urged residents to avoid the area “due to law enforcement activity.”

The F.B.I. confirmed they are on scene and helping the local authorities.
