Fire breaks out at Camp Pendleton base

SAN DIEGO (AP) — Fire crews are fighting a brushfire near Camp Pendleton Marine Corps base.

Marine Corps officials said Wednesday that the blaze started at about 9:45 a.m. at the Naval Weapons Station in Fallbrook, north of San Diego.

Officials say the fire has spread to more than 100 acres and residents in military housing have been ordered to evacuate.

Authorities also have ordered the evacuation of Mary Fay Pendleton Elementary School, located on base.

The cause of the fire is under investigation.

Flames from a burning big rig on Interstate 5 on the northern Camp Pendleton coast have spread to about 3 acres of brush. The California Highway Patrol says at least one lane in each direction remains open, but traffic is backing up. It's unclear why the truck caught fire.
