a Mossad section chief in Brussels, who was shocked at news of Bseiso's killing, Bseiso had been removed from the list in 1988 with the approval of Nahum Admoni. It had apparently been put back on the personal initiative of Shabtai Shavit, who then directed the operation. Shavit was convinced Bseiso was implicated in the Munich attack, and Aaron J. Klein's account endorses this theory, as does John Macintyre in reviewing Klein, though he adds that many Palestinians assassinated for involvement in the Munich massacre were not directly linked to it. The CIA agent Robert Baer, one of the officials Bseiso was to meet the following day, stated that one primary reason for Mossad's killing of Bseiso was to block the growing international recognition of the PLO arising in part from the organization's links with key Western intelligence agencies. The operation to assassinate him relied on key details concerning Bseiso's movements supplied to a Mossad agent, posing as an Iranian government official, by Adnan Yassin in exchange for money. Other sources state he was turned by the Tzomet ("Crossroads") unit while in France where his wife was undergoing treatment for cancer. Israeli sources suggest Yassin was greedy for money: the French investigators concluded that Yassin passed on information in exchange for assistance in paying his wife's medical expenses for cancer treatment in a Paris hospital. French intelligence, while privately fingering Mossad, at the time announced publicly that the responsibility for his death was to be traced to the Abu Nidal Organization, a claim made by an anonymous telephone caller stating he represented Abu Nidal, but which was quickly denied by that group. An anonymous caller phoned the bureau of the United Press International, claiming the murder was the handiwork of the Kahane Chai organization, and executed to revenge the killing of Rabbi Meir Kahane. The PLO pointed the finger at Mossad, which is now known to have organized his killing. At the time, Ehud Gol, spokesman for the Israeli Prime Minister Yitzhak Shamir, stated that claims of Israel's responsibility were "completely ridiculous" and did not merit a reply. Some Israeli authorities suggested it was the work of a rival Palestinian faction. General Uri Sagi, head of Israel's military intelligence claimed that Bseiso had been involved in both the 1972 Munich Olympics massacre, a failed attempt on the life of the Jordanian ambassador to London, and an abortive attack on an
