PARADISE, Calif. (Reuters) - Rescue workers searched on Friday for 630 people reported missing in a northern California town reduced to ashes by the deadliest wildfire in state history. At least 63 people were killed in and around Paradise by the Camp Fire that erupted a week ago in the Sierra foothills 175 miles (280 km) north of San Francisco. The fire is among the most lethal U.S. wildfires since 2000.
