BEAUMONT, Calif. - A rapidly spreading wildfire chewed through a rugged Southern California mountain range on Thursday, destroying at least 10 homes, threatening more than 500 other residences and forcing some 1,500 people to flee.
Five people were injured, while more than 1,000 firefighters, 13 helicopters and six air tankers battled the flames as they pushed eastward along the San Jacinto Mountains, a desert range 90 miles east of Los Angeles.
The Silver Fire was estimated to have burned 11,000 acres Thursday, with 10 percent containment.
There is concern the direction could change in the area, which is known as a wind tunnel.
Authorities still have not determined what caused the fire.
Evacuation orders have been issued in five towns.
The Lakeside Fire District said local crews were sent to help battle the fire.
