of respect for Arafat, whom he hailed as "a man of courage". The next day, Arafat's body was flown from Paris aboard a French Air Force transport plane to Cairo, Egypt, for a brief military funeral there, attended by several heads of states, prime ministers and foreign ministers. Egypt's top Muslim cleric Sayed Tantawi led mourning prayers preceding the funeral procession. Israel refused Arafat's wish to be buried near the Masjid Al-Aqsa or anywhere in Jerusalem, citing security concerns. Israel also feared that his burial would strengthen Palestinian claims to East Jerusalem. Following the Cairo procession, Arafat was "temporarily" buried within the Mukataa in Ramallah; tens of thousands of Palestinians attended the ceremony. Arafat was buried in a stone, rather than wooden, coffin, and Palestinian spokesman Saeb Erekat said that Arafat would be reburied in East Jerusalem following the establishment of a Palestinian state. After Sheikh Taissir Tamimi discovered that Arafat was buried improperly and in a coffin—which is not in accordance with Islamic law—Arafat was reburied on the morning of 13 November at around 3:00 am. On 10 November 2007, prior to the third anniversary of Arafat's death, President Mahmoud Abbas unveiled a mausoleum for Arafat near his tomb in commemoration of him. Theories about the cause of death Numerous theories have circulated regarding Arafat's death, with the most prominent being poisoning (possibly by polonium) and AIDS-related illnesses, as well as liver disease or a platelet disorder. In September 2005, an Israeli AIDS expert claimed that Arafat bore all the symptoms of AIDS based on obtained medical records. But others, including Patrice Mangin of the University of Lausanne and The New York Times, disagreed with this claim, insisting that Arafat's record indicated that it was highly unlikely that the cause of his death was AIDS. Arafat's personal doctor Ashraf al-Kurdi and aide Bassam Abu Sharif maintained that Arafat was poisoned, possibly by thallium. A senior Israeli physician concluded that Arafat died from food poisoning. Both Israeli and Palestinian officials have denied claims that Arafat was poisoned. Palestinian foreign minister Nabil Shaath ruled out poisoning after talks with Arafat's French doctors. On 4 July 2012, Al Jazeera published the results of a nine-month investigation, which revealed that none of the causes of Arafat's death suggested in several rumors could be true. Tests carried out by a Swiss scientific experts found traces of polonium in quantities much higher than could occur
