Mohammed Rashid, an alleged Palestinian terrorist held in Greece pending a high court ruling on a U.S. extradition request, was sentenced to another eight months in jail on a weapons possession charge, court officials said. The United States wants to put Rashid on trial for his alleged role in the bombing of an American airliner over Hawaii in 1982 in which one person was killed. A Greek court found Rashid guilty of possessing two homemade knives, found by prison guards during a routine check of his cell. Rashid has appealed the sentence, and officials said that under Greek law, he may pay a fine instead of serving the jail term. Rashid was arrested last May for entering Greece illegally.
