On August 14, 1929, after attacks on individual Jews praying at the Wall, 6,000 Jews demonstrated in Tel Aviv, shouting "The Wall is ours." The next day, the Jewish fast of Tisha B'Av, 300 youths raised the Zionist flag and sang Hatikva at the Wall. The day after, on August 16, an organized mob of 2,000 Muslim Arabs descended on the Western Wall, injuring the beadle and burning prayer books, liturgical fixtures and notes of supplication. The rioting spread to the Jewish commercial area of town, and was followed a few days later by the Hebron massacre.
