Authorities say a sniper ambushed firefighters responding to a blaze in an Idaho mountain community, killing at least two people.

Two firefighters were killed Sunday and another was wounded when they were ambushed by sniper fire while responding to a blaze in a northern Idaho mountain community, as crews endured a barrage of gunfire over several hours that the governor called a “heinous” assault.

Authorities say a suspect shot at firefighters responding to fire near Coeur d’Alene, Idaho, and the sheriff said two people were killed and police were still “taking sniper fire” Sunday afternoon. The Kootenai County Sheriff’s Office said crews responded to a fire at Canfield Mountain around 1:30 p.
