Former Palestinian foreign minister Nasser al-Qudwa, a nephew of Yasser Arafat, holds a slab bearing an engraving of a portrait of the late Palestinian leader during a press conference he held in the West Bank city of Ramallah on November 8, 2009, three days before the fifth anniversary of Arafat's mysterious death in a Paris hospital on November 11, 2004. Qudwa, who currently heads the 'Arafat Institute' said he expects to receive evidence soon proving that the Palestinian leader was poisoned. Five years have passed, yet the mystery surrounding Arafat's dramatic demise seems just as impenetrable, with many senior officials still holding strong to the belief their leader was poisoned.
