Canada has joined an international campaign urging a moment of silence<br />at the opening of the London Olympics to mark the 40th anniversary of<br />the killing of 11 Israeli athletes at the 1972 Munich Games. Canada's<br />House of Commons unanimously passed a motion to commemorate the tragic<br />event. Last month The IOC ruled out any possibility of a tribute to<br />the Israeli athletes at the opening ceremony, leaving Israeli<br />politicians fuming.
