According to local media accounts, four Sri Lankan fishermen died and two are severely ill after consumption of an unknown substance from bottles found at sea.
The sailors were believed to be on a fishing adventure when they found the bottles, about 320 nautical miles from Tangalle, a town on the island's southern shore.
The Sri Lanka Navy told reporters that the fisherman had drunk from the bottles, believing they contained alcohol.
