A Filipino seafarer has died but three others have been released in West Africa following their abduction from a Greek tanker last month.

A statement by the owner of the 94,100-dwt Elka Aristotle (built 2003) said a Greek, a Filipino and a Georgian were in good health, according to Greek media on Friday.

But the fourth man taken from the ship had died, the company added, saying it appeared this was down to illness and not the actions of the gunmen.
