SEOUL - About 3,000 residents hit by South Korea's worst oil spill protested Tuesday outside the headquarters of the Samsung group, whose vessel was blamed for causing the leakage.

Fisherman and others rallied peacefully outside the building to demand greater compensation, displaying a funeral bier to commemorate three residents who killed themselves over the disaster. The accident happened when a barge carrying a construction crane broke free after a cable to one of two tugs snapped in December 2007.
