A huge, fast-moving and rapidly growing wildfire in northern California is damaging homes and has forced more than 4,000 people to evacuate as firefighters battle gusty winds and perilously dry conditions, authorities have said. Fueled by a crushing heatwave, the so-called Park Fire -- the most intense wildfire to hit the state this summer -- has rapidly devoured nearly 240,000 acres (97,000 hectares) as of Friday night and is continuing to gain strength.
