LOS ANGELES — A wildfire erupted in Los Angeles’ exclusive Bel-Air section Wednesday as yet another part of Southern California found itself under siege from an outbreak of wind-whipped blazes that have consumed multimillion-dollar houses and tract homes alike.

Hundreds of homes across the L.A. metropolitan area and beyond were feared destroyed since Monday, but firefighters were only slowly managing to make their way into some of the hard-hit areas.

As many as five fires have closed highways, schools and museums, shut down production of TV series and cast a hazardous haze over the region. About 200,000 people were under evacuation orders. No deaths and only a few injuries were reported.

From the beachside city of Ventura, where rows of homes were leveled, to the rugged foothills north of Los Angeles, where stable owners had to evacuate horses in trailers, to Bel-Air, where the rich and famous have sweeping views of L.A. below, fierce Santa Ana winds sweeping in from the desert fanned the flames and fears.

“God willing, this will slow down so the firefighters can do their job,” said Maurice Kaboud, who ignored an evacuation order and stood in his backyard with a garden hose at the ready.
