Los Angeles, Dhu-AlQa'dah 14, 1437, Aug 17, 2016, SPA -- Tens of thousands of people in southern California were ordered to flee a raging wildfire that burned out of control Wednesday in a rural mountain area, dpa cited authorities as saying. The Blue Cut fire in Cajon Pass, about 100 kilometres east of Los Angeles in San Bernardino County, started Tuesday morning and by early Wednesday had mushroomed to an inferno covering more than 121 square kilometres, the National Wildfire Coordinating Group said. More than 82,000 people were under a mandatory evacuation order in the face of what authorities called "imminent threat to public safety, rail traffic and structures." News video showed houses on fire and at least one local business, a well-known roadside diner, has been destroyed in the blaze, according to the Los Angeles Times. The fire closed a maze of roads, including a major interstate highway linking Los Angeles and Las Vegas. More than 1,300 firefighters were battling the fire but had yet to gain control, authorities said. Air tankers and helicopters swept over the flames as ground crews from more than 150 fire trucks fought the blaze from below. Two firefighters were injured Tuesday when a firefighting team was trapped by flames. Bone-dry, gusty winds and temperatures over 35 degrees Celsius in the area were expected to fan the flames at least through Thursday. California Governor Jerry Brown Tuesday declared a state of emergency for San Bernardino County, saying the fire was too big for the region to fight alone. In his order, Brown linked the severity of the blaze and others burning in the state to a five-year drought that has turned fields and forests to tinder and killed millions of trees across the state, leaving ready fuel for fire. --SPA 20:38 LOCAL TIME 17:38 GMT www.spa.gov.sa/w
