Classified documents have revealed that Western nations, including Britain and the United States, provided Israel's Mossad with intelligence information in the 1970s that aided in identifying, tracking, and eliminating terrorists responsible for the massacre of athletes at the Munich Olympics, reported The Guardian.
The article exposes that during the 1970s, Western intelligence agencies – including those from Britain, the US, France, and Switzerland – transferred secret information to Mossad that assisted in locating and eliminating individuals suspected of terrorism in Europe, as part of "Operation Wrath of God" following the Munich massacre. This information flowed through a previously undisclosed secret system named "Kilowatt," operating without political oversight. The documents also revealed instances of identification errors and operations conducted based on intelligence received from Western sources.

The first terrorist eliminated as part of the operation was Wael Adel Zuaiter, considered one of the leaders of Black September in Europe – responsible for, among other activities, an attempted attack on an El Al airplane. According to information from the "Kilowatt" network, Israel received multiple updates from Western intelligence services confirming that Zuaiter supplied weapons and logistical assistance to the Black September organization.
Another case revealed in the documents involves Ali Hassan Salameh, the head of the Black September organization. British intelligence provided Mossad with a photograph of the terrorist who orchestrated the massacre. In July 1973, Mossad believed they had identified Salameh in the Norwegian city of Lillehammer and used the photo supplied by MI5 for identification purposes. The agents killed a person who turned out not to be Salameh but rather a Moroccan named Ahmed Bouchikhi. The Mossad operatives were subsequently arrested by Norwegian authorities and sentenced to prison in what later became known as the "Lillehammer Affair."
