Two firefighters were killed and a third wounded Sunday when they were shot as they responded to a wildfire on an Idaho mountain that was set to lure them into an ambush, authorities said.A tactical response team used cell phone data to zero in on a wooded area where they found the body of what's believed to be the lone suspect and a rifle nearby as flames were rapidly approaching,

Kootenai County Emergency Management has told people in the area to shelter in place and asked others to avoid the area.

A brush fire was set deliberately so a sniper could ambush firefighters, authorities said.
