A wildfire has burned about 3 square miles of grass and brush on ridges of the Coronado National Forest about a dozen miles from Nogales in rural Santa Cruz County in southern Arizona.
The Soldier Basin fire is some five miles east of the Nogales airport, which is seven miles northeast of the southern Arizona city of Nogales.
The Forest Service says the 2,500-acre fire is human-caused fire and is 5 percent contained.
It isn't threatening any structures.
The fire began Friday night and is being fought by about 200 firefighters who are building lines to stop the fire's spread.
