Bulldozer operator killed in wildfire

Crews hoping to contain a deadly wildfire burning in rugged, drought-stricken terrain north of Los Angeles made steady progress on Wednesday, after a bulldozer operator fighting a smaller blaze in central California died when the tractor overturned. Some 3,000 firefighters battling the so-called Sand Fire in the Angeles National Forest extended containment lines around 40 percent of the 15,520-hectare on Wednesday, according to fire information officer Sam Wu.
