A search is under way in order to find the missing persons who were aboard on the cargo ship, under Tonga flag, which sank within 30 nautical miles west of Crete.

Seven members of the crew were on the ship Ag-Marina, who are probably Russians. According to information, four people were rescued by another cargo ship which rushed to help, while three more are missing.

Four other cargo ships, a Super Puma helicopter and a coast guard vessel participate in the search efforts.

Until now, it is not known what the ship was carrying, its departure point nor its destination.
