Wildfires burning in Los Angeles County have left five people dead and burned thousands of structures to the ground this week, becoming some of the most destructive the area has seen in decades.

Wildfires menacing Los Angeles have killed at least 10 people and devoured nearly 10,000 structures, with five fires burning into a third night on Thursday, as dry desert winds fanning the flames again gathered strength.

Out-of-control wildfires are ripping across parts of Los Angeles, leading to at least five deaths, burning down hundreds of buildings, and prompting more than 130,000 people to flee their homes in America's second-largest city.
