A 200-acre wildfire is burning on the Tohono O'odham Indian Reservation southwest of Tucson.
The fire was reported Tuesday evening burning southwest of the village of Pan Tak, which is south of Arizona 86 and east of the community of Sells.
No structures are threatened and there are no evacuations, according to a news release from the tribe.
Crews are working to contain the fire's perimeter.
A fire on the Babacomari Ranch in Sonoita has spread to about 450 acres since it started around 12:30 p.m. Wednesday.
Crews from Sonoita-Elgin Fire District, Bureau of Land Management, Arizona State Forestry Division, Patagonia, Fort Huachuca, Mescal, and Benson are fighting the blaze, which is burning south of the Mustang Mountains on private land, said Katie Goodwin, a spokeswoman for Sonoita-Elgin fire.
The fire was started by a vehicle fire that spread into the brush, Goodwin said.
It is still actively burning and cres are conducting burnout operations.
Type 3 and Type 6 engines are being used to fight the fire. Air support was used earlier, Goodwin said.
