The death toll from an explosive wildfire raging in northern California has risen to four, after two more bodies were found within the burn zone in the remote Klamath national forest.

Search teams discovered two bodies on Monday at separate residences along State Route 96, one of the only roads in and out of the region near the state line with Oregon, the Siskiyou county sheriff's office said in a statement.
