Rogge heckled as Black September victims are remembered
Prime Minister David Cameron has attended an event to mark the 40th anniversary of the deaths of 11 Israeli athletes killed at the Munich 1972 Olympic Games.
He said the world must never forget the 11 Israelis and one German police officer killed by the Black September Palestinian group in 1972.
Jacques Rogge was criticised for ruling out holding a moment of silence at the opening ceremony.
