NOGALES, Ariz. -- A wildfire has now burned about 7 square miles of grass and brush on ridges of the Coronado National Forest in southern Arizona.
The Soldier Basin fire is some five miles east of the Nogales airport in steep, rocky terrain in Santa Cruz County.
Forest Service officials say the 6,000-acre human-caused fire was 15 percent contained by Wednesday.
They say the wildfire isn't threatening any structures.
The fire began last Friday night and is being fought by about 200 firefighters plus three helicopters, 11 engines and seven water tenders.
