Two Bangladeshi barges, one of them carrying fly ash and the other aluminium, headed for Bangladesh, capsized in separate places in South 24-Parganas on Thursday.

MV Tofa Tarif-4 sank at C Tangrar Char between Kulpi and Nischindipur around 8.30am on Thursday, while MV Dhruv Rupanti sank near the Kakdwip tower in the afternoon.

All the crew members on both barges were rescued and taken to local government hospitals, where they have been kept in isolation from other patients.
