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 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 (Andreas Baader and Ulrike Meinhof) be released. Black September called the operation "Iqrit and Biram", after two Palestinian Christian villages whose inhabitants were expelled by the Haganah in 1948.
