Two Americans abducted off the Nigerian coast last month from a vessel contracted to the Chevron oil company have been released, the U.S. embassy in Abuja said on Friday, according to Reuters. A Mexican citizen was also released, Nigerian security sources said. The embassy gave no further details about how they were freed but the sources said ransom demands had been discussed. Eight pirates boarded the oil supply vessel contracted to the U.S. energy giant on Nov. 17, taking the three hostages. -- SPA
