After a failed rescue attempt, all hostages and all but three of terrorists were killed. All Olympic events were suspended for one day after the terrorist action became known. They were continued a day later, although some athletes decided to leave Munich. Mark Spitz set seven World Records to win a record seven gold medals in one Olympics.
