French manhunt underway after shooting of Greek priest

French police interrogated one suspect and searched for others Sunday after a Greek Orthodox priest was shot and critically wounded while closing the door to his church in the French city of Lyon. Investigators are trying to determine whether a man arrested Saturday night was the gunman behind the attack, or has information about it, according to a police official. The attack came as France is under high security alert after the killing of three people at a Nice church on Thursday, amid global tensions over cartoons of the Muslim Prophet Muhammad published in a French newspaper.
