All 12 crew have been rescued from a cement carrier that sank off Mexico on Thursday.
The 3,400-dwt Duban (built 1983) went down about 24 km off the port of Huatulco, domestic media reported.
The Diario Marca newspaper said the navy picked up the 12 seafarers.
The Togo-flagged vessel was carrying 1,500 tonnes of cement to the port of Manzanillo at the time.
