Four crewmen died and five are still missing after an Indian ship sank in bad weather off the coast of Oman, state media in the Gulf sultanate reported on Sunday. The Omani coastguard rescued six sailors and recovered four bodies after the sinking around 12 kilometres off the town of Sadh in the southern Dhofar region, reports said. Torrential rains this week sparked flashflooding in Dhofar that killed 12 people, authorities in the region said.
