The world must “never forget” the 11 Israeli athletes killed by Palestinian gunmen at the 1972 Munich Olympics, British prime minister David Cameron said at an event to mark the 40th anniversary of the terrorist attack.

Widows of two Israeli athletes killed at the 1972 Olympics pleaded with the International Olympic Committee to allow a minute’s silence at the London 2012 opening ceremony.

Director Steven Spielberg said he is “very proud” of two early endorsements from the widows of two of the 11 Israeli athletes killed in the 1972 Olympic massacre detailed in his controversial new film, Munich.
