The Latest: San Diego fire burns 3,600 acres
A fast-growing wildfire fanned by Santa Ana winds in rural San Diego County has burned 3,600 acres.
State fire authorities said Thursday more than five buildings have been destroyed, an unknown number has been damaged and more than 1,000 others are threatened around Bonsall. The picturesque community of 4,000 people amid rolling hills is known for its equestrian facilities.
Officials shut down state Highway 76 in both directions, ordered mandatory evacuations around Bonsall and opened shelters at schools and casinos. The blaze started shortly after 11 a.m.
State officials said the military was assisting with helicopters. The area is near Camp Pendleton Marine Corps Base.
It's the latest wind-driven fire in Southern California, including destructive blazes to the northwest in Los Angeles and Ventura counties.
