Abdul Majid Giaka (/ˈɑːbdʊl məˈdʒiːd ˈdʒaɪɑːkə/ AHB-duul mə-JEED JY-ah-kə; born 1960) is an alleged double agent who defected from Jamahiriya el-Mukhabarat (Libyan intelligence service) and became a CIA asset in August 1988. Giaka's testimony at the Pan Am Flight 103 bombing trial in September 2000, which led to the conviction of Abdelbaset al-Megrahi of sabotaging Pan Am Flight 103 on 21 December 1988, was called into question by the Scottish Criminal Cases Review Commission in June 2007.
