All crew were reported to be safe following a tanker hijacking off Ivory Coast that could indicate a broadening of piracy operations in West Africa.
Security company Dryad Global said the 5,700-dwt B Ocean (built 2009), operated by SK Shipping of South Korea, came under attack late on Monday, 53 miles south-west of Abidjan.
The fuel cargo on board was stolen, but no damage was reported to the ship.
