After 33 years of secrecy, the U.S. State Department declassified a document [pdf format] admitting it knew Yasser Arafat, chairman of the Palestine Liberation Organization, plotted and supervised the murders of two U.S. diplomats in Sudan in 1973. The document makes it clear the Khartoum operation “was planned and carried out with the full knowledge and personal approval” of Arafat. In the attack on March 1, 1973, eight members of the Black September terrorist organization, part of Arafat's Fatah faction of the PLO, stormed the Saudi embassy in Khartoum on Arafat's orders, taking U.S. Ambassador Cleo Noel, diplomat Charge d'Affaires George Curtis Moore and others hostage. The following day, the terrorists killed Noel, Moore and Belgian diplomat Guy Eid.
