A Greek oil tanker with more than 2,000 tons of oil on board sank near Athens Monday.
Ten crewmembers were rescued, but the tanker's 48-year-old captain was later found dead, BBC reported.
The captain stayed on board the sinking ship, and divers later retreived his body, BBC said.
The ship, a refuelling vessel named the Alpha 1, was carrying a mixture of fuel oil and diesel.
It may have hit something - potentially the remains of an old shipwreck - in the shallow bay of Eleusina, near Athens, officials told Reuters.
The officials said no oil appeared to be leaking from the ship. The officials placed a plastic barrier around the tanker to contain oil spills, BBC said.
The tanker belongs to the Greek company Viamar, Bloomberg reported.
