The crew of a Chinese trawler and a South Korean patrol ship have clashed, leaving one fisherman dead and two missing, South Korean officials say.
The clash reportedly happened as the coast guards tried to prevent Chinese boats from fishing illegally off South Korea's west coast.
Video filmed by the coast guard shows officers fighting with fishermen wielding metal bars.
Four coast guard officers were injured, reports say.
About 50 Chinese fishing boats were in the area at the time of the clash, coast guard spokesman Ji Kwan-tae said, according to AP news agency.
One of the boats intentionally struck the coast guard ship to try to allow the others to sail back into their waters, he said - but the boat sank after the impact.
At least eight men were rescued from the sea, but one later died.
More guard boats and helicopters were sent to the area to try to locate two missing fishermen. BBC News
