Members of Congress are renewing their call for the International Olympic Committee to acknowledge the 1972 Munich games massacre that led to the deaths of 11 members of the Israeli national team.

Congressional members held a moment of silence at the Capitol Thursday to mark the 40th anniversary of the incident.

They want to see a similar remembrance during the opening ceremonies in London.

The Israeli athletes were among 12 people killed when the Palestinian terrorist group "Black September" took over their housing quarters in the Olympic Village.

"I have three words for the International Olympic Committee: 'shame on you.' 40 years later, after the brutal murder of the Israeli athletes, there has never been a moment of silence or any kind of commemoration,” said Rep. Eliot Engel.

“We are guided by the saying 'Never Forget,’" said Rep. Steve Israel. "The International Olympic Committee may want to forget but we won’t let them."

In a letter to the delegation, the IOC said it has paid tribute to the memory of the athletes who died in Munich and will continue to do so.
