The owners of a Spanish oil tanker that was hijacked off West Africa 10 days ago says the vessel has been freed and the 23-member crew is OK. Consultores de Navegacion spokeswoman Sheena Campbell said the Mattheos I was released by pirates Saturday morning. She said no ransom was paid, though the pirates stole some of the diesel fuel the ship was carrying as cargo. The ship is now off the coast of Nigeria. The Spanish Foreign Ministry also confirmed the ship had been released, according to a report of the Associated Press.
