Wildfires raged for the third straight day, destroying swaths of America’s most populated county and displacing tens of thousands of residents, with firefighters struggling to contain the biggest blazes.

Fierce wildfires are raging in the Los Angeles area, with fast-moving flames burning through homes and businesses. Residents are fleeing smoke-filled canyons.

Evacuees sought refuge and medical care at a Red Cross-run evacuation shelter at the Westwood Recreation Center in Los Angeles. In the hilly areas east and north of downtown off Sunset Boulevard, many homes were almost completely destroyed by the Palisades fire.
