Szulc 1991, p. 275: "By mid-1963, Operation Yakhin had become virtually routine. Colonel Oufkir, the new Interior Minister in Morocco, and Meir Amit, the new chief of the Mossad, concluded a secret pact that year providing for the training of Moroccan security services by the Israelis and limited covert military assistance in exchange for a flow of intelligence on Arab affairs and continued free departures of Jews. In 1965, the Mossad rendered Oufkir the shocking and sinister service of tracking down Mehdi Ben-Barka, the leader of the leftist opposition in Morocco, whom both the king and his Interior Minister wished dead. Amit agreed to locate Ben-Barka, and Mossad agents persuaded him to come to Paris from Geneva under false pretenses. Near a restaurant, French plainclothesmen arrested Ben-Barka and handed him over to Oufkir’s agents. They then took him to the countryside, killed him and buried him in a garden. Investigations by the French government uncovered the truth, and the Ben-Barka affair became a political scandal in France, Morocco and Israel.” Szulc, Tad (1991).

Il est possible que le roi savait. Il est légitime de penser que de Gaulle était en possession d'informations... Le problème est qu'aujourd'hui les protagonistes sont tous morts» in Affaire Ben Barka : Driss Basri chez le juge, Le Figaro, 23 May 2006 (in French)
