In 1929 tensions grew over the Kotel (Wailing Wall), the holiest spot in the world for Judaism, a narrow alleyway where the British banned Jews from using chairs or curtains: Many of the worshippers were elderly and needed seats; they also wanted to separate women from men. The Mufti claimed it was Muslim property and deliberately had cattle driven through the alley. He alleged that the Jews were seeking control of the Temple Mount. This (and general animosity) led to the August 1929 Palestine riots. The main victims were the (non-Zionist) ancient Jewish community at Hebron, who were massacred. The riots led to right-wing Zionists establishing their own militia in 1931, the Irgun Tzvai Leumi (National Military Organization, known in Hebrew by its acronym "Etzel").
