LOS ANGELES, Oct. 26 (Xinhua) -- Fast-moving wildfires have left two U.S. firefighters critically injured and forced tens of thousands of residents in Orange County in Southern California to evacuate amid high winds on Monday.
One blaze, dubbed "the Silverado Fire," which started Friday morning in the area of Santiago Canyon Road and Silverado Canyon Road, has exploded to more than 7,200 acres (29.1 square km) in hours, according to the Orange County Fire Authority.
A total of 500 firefighters are battling on the scene amid erratic winds that can reach up to 96 km to 112 km per hour. Officials said that air support has been grounded due to high winds.
