A blaze that ignited overnight in a single-family home injured two firefighters and forced residents of a rustic Southern California canyon to flee their homes Thursday, as flames tore across about 4,000 acres of dry brush and wooded hillsides.
The Bond Fire, which broke out about 10 p.m. Wednesday night, was driven through Silverado Canyon in Orange County by gusty Santa Ana winds. Authorities issued evacuation warnings to thousands of people.
About 500 firefighters aided by water-dropping aircraft battled the flames, which sent smoke drifting across Orange and Los Angeles counties, but had not achieved any containment as of midafternoon Thursday.
Since the start of the year, wildfires have scorched more than 6,500 square miles (17,000 square km) of California land according to the California Department of Forestry and Fire Protection.
