A marine tanker carrying industrial fuel sank in rough seas off the Philippines on Thursday, causing a large oil spill as coast guard rescuers search for a missing crew member, officials said.

Sixteen of the 17 crew members of MT Terra Nova have been rescued, Transportation Secretary Jaime Bautista said, after the ship capsized off the coastal town of Limay in Bataan province.

A search is underway for the missing sailor.
