Diamond Harbour, July 17: At least 19 fishermen have gone missing after their boat capsized in the sea, off Frazerganj harbour, in Sundarban area of south Bengal, officials said today. A senior police officer said a hovercraft and an aeroplane have been pressed into service to look for the missing persons.

Apart from that, coast guard personnel, police officers and members of a fishermen association have also gone out into the sea for the rescue operation, Sunderban Superintendent of Police Tathagata Basu said.

Bijan Maity, the secretary of West Bengal United Fishermen Association, said the men, mostly from Namkhana and Kakdwip areas of South 24 Parganas district, set sail into the Bay of Bengal around 10 am yesterday as there were "no Met department warnings on the radio".

Around 4 pm, however, the sea turned rough and huge waves, accompanied with gusty winds, overturned several trawlers in the sea, he said. "Although many trawlers returned to safety, three boats - MV Malleshwar, MV Joykishan and MV Maa Shibani - capsized in the sea. Around 10 fishermen of MV Joykishan and six of MV Malleshwar, and three more of some other trawlers have gone missing," Maity said. The Met Office website, however, shows that West Bengal fishermen were advised against venturing into the sea yesterday.
