Authorities say firefighters who rushed to put out a blaze in a northern Idaho mountain community found themselves instead in an unexpected shootout.

Shelter-in-place order issued for Hayden Lake Road area near Coeur d’Alene, Idaho, after firefighters were shot while responding to fire on Canfield Mountain.

A man who had intentionally set the fire to ambush the crew on Sunday was perched in a sniper position, firing at the firefighters. They took cover behind firetrucks, but two died and a third was wounded during a barrage of gunfire over several hours, authorities said.
