the van's fixed launchers away from the sky. The unconscious driver was pulled from the van and tossed to the side of the road, and DIGOS was alerted that there had been "an interesting accident they should look into". Zamir briefly considered killing the Palestinian terrorists, but felt that their deaths would serve as an embarrassment to Golda Meir's audience with the pope. The terrorists, who had been involved in the Munich massacre, were taken to the hospital and eventually allowed to fly to Libya, but within months, all were killed by Mossad. Assassinations of other Israelis and international officials Two Israelis suspected of being intelligence agents were shot and killed, as well as an Israeli official in Washington. Baruch Cohen, a Mossad agent in Madrid, was killed on January 23, 1973 by a young Palestinian contact. Mossad then conducted a side operation to locate and kill Cohen's assassins, and at least three Palestinians involved in planning and carrying out Cohen's killing were assassinated. Vittorio Olivares, an Italian El Al employee suspected by Black September, was shot and killed in Rome in April 1973. The Israeli military attaché to the United States, Colonel Yosef Alon, was assassinated on July 1, 1973 in Chevy Chase, Maryland. Alon's killer was never officially identified, and the FBI closed its investigation after failing to identify the culprits, but theorized that Black September was behind the assassination. Fred Burton, former deputy chief of the counterterrorism division of the U.S. State Department's Diplomatic Security Service and Vice-President of the private intelligence and consulting firm Stratfor, conducted an investigation and concluded that Alon's killer was a Black September operative who was killed by Mossad in 2011. Ami Shachori, an agriculture counselor working at the Israeli Embassy in London, was assassinated by Black September on September 19, 1973. Black September conducted several other attacks only indirectly against Israel, including the seizure of Western diplomats in the Saudi embassy in Khartoum (see: 1973 Khartoum diplomatic assassinations), but the group was officially dissolved by al-Fatah in December 1974. Arab reaction While the first wave of assassinations from October 1972 to early 1973 caused greater consternation among Palestinian officials, it was the raid on Lebanon – Operation Spring of Youth in April 1973 – that truly shocked the Arab world. The audacity of the mission, plus the fact that senior leaders such as Yasser Arafat, Abu Iyad and Ali Hassan Salameh
