1973. He also employed the services of Ilich Ramírez Sánchez, better known as "Carlos the Jackal", whom he had met in 1970 and trained in guerrilla warfare techniques. Haddad decided to expel Sánchez from his team after Sánchez had been accused of refusing to kill two hostages, and possibly stealing ransom money, following the 1975 assault on the OPEC conference in Vienna. Haddad organized the Entebbe hijacking in June 1976. Death Haddad died on 28 March 1978 in the German Democratic Republic, reportedly from leukemia. According to the book Striking Back, published by Aaron J. Klein in 2006, Haddad was killed by Mossad, which had sent the chocolate-loving Haddad Belgian chocolates coated with a slow-acting and undetectable poison which caused him to die several months later.

What remained of the PFLP-EO dissolved after his death, but in the process inaugurated the 15 May Organization and the PFLP-SC. KGB agent According to Vasili Mitrokhin, a senior KGB archivist who defected to the UK in 1992, in early 1970 Haddad was recruited by the KGB as an agent, codenamed NATIONALIST. Thereafter, in deep secrecy the Soviets helped to fund and arm the PFLP. The KGB had warning of its major operations and almost certainly sanctioned the most significant, such as the September 1970 hijackings. Haddad remained a highly valued agent till his death in 1978. A letter by KGB chairman Yuri Andropov to Leonid Brezhnev, the Soviet leader and head of the Communist Party, about the covert transfer of arms to the PFLP refers to Haddad as a "trusted KGB intelligence agent". The letter and two other highly classified documents from the CPSU Central Committee archive were located and secretly copied by Vladimir Bukovsky in 1992.
