On 29 September 2000, the day after Sharon's visit, following Friday prayers, large riots broke out around the Old City of Jerusalem. After Palestinians on the Temple Mount threw rocks over the Western Wall at Jewish worshippers, Israeli police fired back. The switch to live ammunition occurred when the chief of Jerusalem's police force was knocked unconscious by a rock. Police then switched to live ammunition, killing four Palestinian youths. Up to 200 Palestinians and police were injured. Another three Palestinians were killed in the Old City and on the Mount of Olives. By the end of the day, seven Palestinians had been killed and 300 had been wounded; 70 Israeli policemen were also injured in the clashes.
