Which Olympics was attacked by Palestinian terrorists?

The Munich massacre was an attack during the 1972 Summer Olympics in Munich, West Germany, at which eleven Israeli Olympic team members were taken hostage and eventually killed, along with a German police officer, by the Palestinian terrorist group Black September. Shortly after the crisis began, they demanded 234 prisoners jailed in Israel and the German-held founders of the Red Army Faction be released. Black September called the operation "Iqrit and Biram".

German neo-Nazis gave the attackers logistical assistance. Police officers killed five of the eight Black September members during a failed rescue attempt. They captured the three survivors, whom West Germany later released following a Lufthansa airliner hijacking in October. Mossad responded to the release with Operation "Spring of Youth" and Operation "Wrath of God", tracking down and killing Palestinians suspected of involvement in the massacre.
