A newly declassified report from 1973 shows that Yasser Arafat personally commanded the terrorist attack that resulted in the murders of Ambassador Cleo Noel and his deputy George Moore, as well as a Belgian diplomat. Moreover, the two murders appear to have been the entire point of Arafat's attack:
The Khartoum operation was planned and carried out with the full knowledge and personal approval of Yassir Arafat, Chairman of the Palestine Liberation Organization (PLO) and the head of Fatah. Fatah representatives based in Khartoum participated in the attack, using a Fatah vehicle to transport the terrorists to the Saudi Arabian embassy.
Initially, the main objective of the attack appeared to be to secure the release of the Fatah/BSO [Black September Organization] leader Muhammed Awadh (Abu Da'ud) from Jordanian captivity. Information acquired subsequently reveals that the Fatah/BSO leaders did not expect Awadh to be freed, and indicates that one of the primary goals of the operation was to strike at the United States because of its efforts to achieve a Middle East peace settlement which many Arabs believe would be inimical to Palestinian interests.
