Arizona ablaze

James Honanie of the Flagstaff Hot Shots removes fuel from the path of the wildfire Monday in Flagstaff, Ariz. More than 300 firefighters battled the Northern Arizona blaze that has threatened homes and forced evacuations.

Authorities said the fire started in a wooded area a couple miles from downtown after Randall Wayne Nicholson — who was arrested Sunday on suspicion of starting the fire — built a small campfire. Investigators believe he dumped hot coals on the ground before leaving the site.
