LOS ANGELES – A wind-whipped wildfire raged on Wednesday into a wealthy Southern California neighborhood, destroying at least six homes, threatening hundreds more and scorching a building at a winery owned by billionaire media mogul Rupert Murdoch.

The so-called Skirball Fire, which erupted early on Wednesday morning as the latest in a rash of major blazes fueled by hot, dry Santa Ana winds, had burned about 150 acres near large estates in the Bel-Air neighborhood of Los Angeles by early afternoon and was only 5 percent contained.
