The Lillehammer affair was the killing by Mossad agents of Ahmed Bouchiki, a Moroccan waiter and brother of the renowned musician Chico Bouchikhi, in Lillehammer, Norway on July 21, 1973. The Israeli agents had mistaken their target for Ali Hassan Salameh, the chief of operations for Black September. Six of the Mossad team of fifteen were captured and convicted of complicity in the killing by the Norwegian justice system, in a major blow to the intelligence agency's reputation.
Undercover agents had been sent by Israel as part of Operation Wrath of God to assassinate Ali Hassan Salameh, the head of Force 17 and an operative of the Black September Organization, a Palestinian militant group that carried out the 1972 Munich Massacre. After an informant misidentified Ahmed Bouchiki as Salameh, a member of the assassination team shot the man four times as he walked back from a cinema to his apartment with his pregnant wife. Author and former Mossad katsa (case officer) Victor Ostrovsky wrote that Salameh was instrumental in leading Mossad off course by feeding it false information about his whereabouts. Two members of the assassination team were arrested the next day as they re-used a getaway car to go to the airport. After their interrogation, more members of the cell were arrested. Though nine others slipped away, the Norwegian authorities held six Mossad agents: four men and two women. Incriminating documents and the keys to a network of safe houses were discovered.
