Husseini was Yassir Arafat's uncle!!!!!!!
There seems to be some doubt - (snip)
"Yasser Arafat was introduced to Mufti and the Mufti would subsequently become the role model and mentor for Arafat. In biographies of Arafat, whose real name is Mohammed el Husseini, the Mufti is stated to be a ìdistant relativeî of Arafat, although this claim has been denied as well. For two years, beginning at the age of 16, Arafat worked for the Mufti and his covert terrorist network and organization, helping to smuggle and buy weapons in the war against Jewish settlers of Palestine. Sheik Hassan Abu Saud, the mufti of al-Shafaria, was worked with the Mufti. The Grand Mufti was a precursor of both the Palestine Liberation Organization (PLO) and of the Palestinian national struggle and movement to maintain a Palestinian state. The terrorism, fanaticism, and ruthlessness of that movement reflect the enduring legacy and influence of the Grand Mufti..."
Uncle or Not?
"The Mufti of Jerusalem, Haj Amin al-Husseini was later the notorious Nazi who mixed Nazi propaganda and Islam. He was wanted for war crimes in Bosnia by Yugoslavia. His mix of militant propagandizing Islam was an inspriation for both Yasser Arafat and Saddam Husein: He was also a close relative of Yasser Arafat and grandfather of the current Temple Mount Mufti. "Arafat's actual name was Abd al-Rahman abd al-Bauf Arafat al-Qud al-Husseini. He shortened it to obscure his kinship with the notorious Nazi and ex-Mufti of Jerusalem, Haj Muhammed Amin al-Husseini." Howard M. Sachar, A HISTORY OF ISRAEL (New York: Knopf, 1976). The Bet Agron International Center in Jerusalem interviewed Arafat's brother and sister, who described the Mufti as a cousin (family member) with tremendous influence on young Yassir after the Mufti returned from Berlin to Cairo. Yasser Arafat himself keeps his exact lineage and birthplace secret. Saddam Hussein was raised in the house of his uncle Khayrallah Tulfah, who was a leader in the Mufti's pro-Nazi coup in Iraq in May 1941."
