Query: In what year did the CIA begin to expect a military coup in Libya?
Context: Anti-western riots broke out in Tripoli and Benghazi, while Libyan workers shut down oil terminals in solidarity with Egypt. By 1969, the U.S. Central Intelligence Agency was expecting segments of Libya's armed forces to launch a coup. Although claims have been made that they knew of Gaddafi's Free Officers Movement, they have since claimed ignorance, stating that they were monitoring Abdul Aziz Shalhi's Black Boots revolutionary group.
