South Korea's worst oil spill blackens west coast

TAEAN, South Korea (Reuters) - South Korean workers using skimmers and containment fences battled on Saturday to clean up the worst oil spill in the country's history, as the slick washed ashore near a nature preserve on the west coast. 

Parts of about 17 kms of coastline about 100 km southwest of Seoul have already been blackened by oil, the coast guard said. More of the spill is expected on Sunday to hit the area that has marine farms and oyster beds.
