Israeli Parliament Member Ariel Sharon's visit to the Temple Mount in September 2000 was used by the PA to spark the five-year terror campaign (the "Intifada") that left thousands dead. According to Mamdouh Nawfal, Arafat's advisor for internal affairs and member of the Palestinian Supreme National Security Council, Arafat summoned the Palestinian leadership just days before Sharon's planned visit to the Al-Aqsa Mosque and told them the following:
"[Arafat said:] 'The Al-Aqsa Mosque is in danger, and as Allah is my witness, I make this known.' [Arafat] spoke with the knowledge that Jerusalem is a special place for the Palestinian nation, for the Arab people and Islam, and with full conviction that it would be easy to involve the Palestinian and Arab street and to motivate them to participate in a battle of defense for Jerusalem and the holy places. He was certain that the masses of believers would hurry to the defense of Al-Aqsa."
[Al-Ayyam, Aug. 30, 2001]
That theme of "al-Aqsa is in danger" already appeared during the 3rd Palestinian Arab Congress in 1920 and most prominently, at the December 1931 General Islamic Conference in Jerusalem.
