The Munich massacre is a common reference name for an attack that occurred during the 1972 Summer Olympics in Munich, Bavaria, in southern West Germany, when 11 members of the Israeli Olympic team were taken hostage and eventually killed, along with a German police officer, by the Palestinian group Black September.[4][5][6] Shortly after the crisis began, they demanded the release of 234 prisoners held in Israeli jails,[7] and the release of the founders (Andreas Baader and Ulrike Meinhof) of the German Red Army Faction, who were held in German prisons.[8] Black September called the operation "Ikrit and Biram",[9] after two Christian Palestinian villages whose inhabitants were expelled by the Haganah in 1948.
