The two biggest wildfires ravaging the Los Angeles area this week burned at least 10,000 homes, buildings and other structures, officials said on Thursday as they urged more people to heed evacuation orders after a new blaze ignited and quickly grew.

The fast-moving Kenneth Fire started in the late afternoon in the San Fernando Valley near the West Hills neighbourhood and close to Ventura County.
