CAMP PENDLETON (CNS) - Two brush fires that have burned a combined 30 acres at Camp Pendleton are expected to be contained Sunday evening, authorities said.

The blaze started about 1 p.m. just northwest of the Oceanside Municipal Golf Course, off Golf Course Road.

Crews began fighting the flames on the ground and eventually called in an aircraft to assist. Containment is expected shortly and crews do not anticipate weather or ground conditions to impact the fire, according to Camp Pendleton Director of Public Affairs Jason Johnston.

No injuries have been reported and no structures are currently in danger, Johnston said.

The cause of the fire has not been determined.
