Michael Ledeen told me of this beautiful deed Sunday but it wasn't reported until now. From Michael Shimulovich of the Times of Israel:

Members of the Italian Olympic delegation held a moment of silence Sunday in memory of the 11 Israeli athletes murdered at the Munich Olympics 40 years ago. Some 30 individuals, among them athletes, the Italian Tourism and Sports Minister Piero Gnudi and the head of the Italian Olympic Committee, Gianni Petrucci, participated in the intimate ceremony.

Also in attendance were the Chairman of the Israeli Olympic Committee, Zvi Varshaviak, and the head of the Israeli delegation, Efraim Zinger.

The moment of silence was held at the entrance to the Israeli delegation's residential compound in London.
