Residents try to remove oil as the crude oil spills over the beach after a Hong-Kong registered oil tanker accident, at the Mallipo swimming beach in Taean, about 170km (106 miles) southwest of Seoul, December 8, 2007. South Korean workers using skimmers and containment fences battled on Saturday to clean up the worst oil spill in the country's history, as part of the slick hit shore near a nature preserve on the west coast.
