What began as a routine response to a brush fire on northern Idaho’s Canfield Mountain turned deadly Sunday after firefighters reported someone shooting at them while they battled the flames.

Firefighters were ambushed by a gunman while responding to a brush fire in Coeur d'Alene, Idaho, on Sunday, according to the local sheriff's office.

Two firefighters were killed and residents were ordered to shelter in place, but the order was lifted after police found a dead man in the woods.
