PARADISE, Calif. (Reuters) - The search for victims of a catastrophic blaze that reduced a northern California town to ashes intensified on Thursday and authorities said the list of those reported missing had expanded to more than 600 in the deadliest wildfire in California history.

At least 63 people have been confirmed dead so far in the Camp Fire, which erupted a week ago in the drought-parched Sierra foothills 175 miles (280 km) north of San Francisco and now ranks as one of the most lethal single U.S. wildfires since the turn of the last century.
