Nearly 8,000 residents of Riverside County in Southern California were forced to evacuate their homes on Saturday as a wildfire spread uncontained across more than 4,000 acres, the County fire department said. The fire - dubbed the Apple Fire by local firefighters, who routinely give blazes identifying names - was reported on Friday in Cherry Valley, a community about 75 miles east of Los Angeles. It had destroyed at least one family home as of Saturday evening (Sunday morning UK time). Photographs shared by the Riverside County fire department on Twitter on Saturday showed thick plumes of smoke filling the sky over the mountainous region. Residents of 2,586 homes, totalling around 7,800 people, were told to evacuate, the department said.
