King Abdullah of Saudi Arabia appointed his half brother, Prince Mogrin bin Abdel Aziz, to head his Gulf country's general intelligence forces on Saturday, the official Saudi Press Agency reported. The post has been vacant since King Fahd, before his death in August, accepted the resignation of the former chief of the intelligence, Prince Nawaf bin Abdel Aziz, for health reasons. Prince Mogrin, 60, has served as a Saudi Air Force pilot and governor of the holy city of Medina. Last week, Abdullah signed a decree forming the National Security Council, which will be in charge of Saudi's intelligence and other security agencies. Prince Bandar bin Sultan, who served as Saudi Ambassador to Washington for 22 years until resigning in July, was appointed chief of the NSC.
