The 1972 Munich Olympics Massacre

Palestinian militants from the Black September organisation took 11 Israeli athletes hostage at the 1972 Munich Olympics. All 11 hostages, five terrorists, and one German police officer were killed during a botched rescue attempt. IOC President Avery Brundage's decision to continue the Games after a brief memorial — declaring "the Games must go on" — remains one of the most controversial calls in Olympic history and raised permanent questions about security, politics, and sport.
