The U.S. Forest Service reported late Wednesday morning that a wildfire burning in grass and brushland on both sides of the Arizona-Mexican border was 75 percent contained after scorching 9,000 acres.

The fire was moving slowly, and crews were patrolling the perimeter, mostly mopping up, the Coronado National Forest reported on its Incident Information System website.

The fire began in Mexico, where it had burned an estimated 2,000 acres by late Wednesday morning. On the U.S. side, it had burned more than 7,000 acres, the website report said.

No structures were threatened. The Forest Service reported that it had evacuated a campground at Parker Canyon Lake, south of Sierra Vista.

The fire is called the School Canyon Fire and was being battled by 60 ground crew and several aircraft making drops in the Coronado Forest's Sierra Vista Ranger District.
