Multiple agencies are working to extinguish a fire that has spread quickly south of Tucson.
Officials say the Sawmill Fire ignited about 10 miles southeast of Green Valley around 11 a.m. Sunday, and had burned an estimated 2,000 acres by the evening hours.
The flames burned through grass and brush on Arizona Department of Forestry land, and authorities said at least six people had been evacuated as a precautionary measure.
The fire was 5 percent contained, though it remained active and was spread by gusty conditions and low humidity. Officials estimated the first would be fully contained by April 25.
Firefighters said the wildfire's cause is still under investigation.
Further information was not immediately available.
