Let's not forget this:
the second bloody massacre of Jews by the Arabs took place, in 1929. The story put about that the Jews planned to tear down the Mosque of Omar, and to rebuild the Temple on the site – a tactic that has been used to arouse the Arabs to this day.and elaborated:

Communication between Jerusalem and Mecca is constantly going on, and our proceedings, as my noble friend said, are creating unrest throughout the whole of the Arab world. In Mecca not long ago leaflets were being handed about among pilgrims from the most distant parts in which the Zionist flag was represented as adorning the Mosque of Omar and one can easily imagine how inflammatory must be leaflets of that kind among the Arab and Moslem...
