Chittagong: Four lighter vessels, loaded with different goods, capsized in several points of the Bay of Bengal early on Wednesday due to poor visibility.

Mahbubur Rashid, Executive Director of the Water Transport Coordination Committee, said the four vessels sank in the Bay with cement clinker, sugar, maize and raw phosphate.

Labs-1, carrying cement clinker, hit a char near the River Karnafuli estuary due to poor visibility triggered by dense fog and overturned, Rashid said.

Later, the ship went under water during the high tide, he added.

Another vessel, Glory Srinagar-4, collided with a ship at Bhashanchar in Swandip upazila in the Bay due to the opaque visibility amid dense fog and capsized with some 1,550 tonnes of maize on board at about 8:30am.

Garindasa, carrying some 1500 tonnes of sugar, sank at Kashiar Char in the Bay at about 10:00am. However, the reason behind the accident could not be known immediately.

Meanwhile, MV Manjur, fully loaded with raw-phosphate, capsized adjacent to Patenga beach as the sailor lost his control over the vessel.
