Thai Marine Police were searching on Friday for 11 missing crew members of a Bangladesh cargo vessel that sank in rough seas near the Thai resort island of Phuket.

Naval officers said the MV Hope was battered by rough seas and high winds and sank on Thursday morning off Racha Noi island, south of Phuket, in the Andaman Sea.

They said the ship’s distress call was relayed to the Thai navy, which rescued six of the crew members.

Marine Police Lieutenant Colonel Prasert Sripoonrat said a Thai warship with a helicopter had been sent out early on Friday to search for the 11 missing men but the mission was being hampered by bad weather.
