TUCSON, Ariz. -- More than 100 firefighters have been working to contain a wildfire burning in the Coronado National Forest east of Tucson.
The Redington Fire was reported about 4 p.m. Saturday and had burned 125 acres by nightfall, according to the U.S. Forest Service.
It was declared 50 percent contained by 11:15 a.m. Sunday and is smoldering in rough terrain.
Crews worked through the night, and an air tanker created a retardant barrier northeast and southeast of the fire Saturday evening.
Resources assigned include 110 firefighters, three engines, three water tenders and one helicopter.
Some equipment has been released to other assignments but resources remain at the hot spots, the U.S. Forest Service said.
Redington Road is closed between mileposts 5 and 17 until further notice, and a temporary flight restriction is in place over the area. The fire is burning near milepost 12.5 in the Catalina District of the forest.
The fire is still under investigation but is believed to be human caused.
