According to the Egyptian government, the bombers were
Palestinians who had tried to enter Israel to carry out attacks there but were unsuccessful. They claimed that the mastermind, Iyad Saleh, recruited Egyptians and Bedouins to find explosives to be used in the attacks. Beginning in March 2004, the bombers used
washing machine timers,
mobile phones and modified
gas cylinders to build the bombs. They used
TNT and old explosives found in the Sinai (as it was many times a war zone), which were purchased from Bedouins, to complete the bombs. Egypt has said that Saleh and one of his aides, Suleiman Ahmed Saleh Flayfil, died in the Hilton blast, apparently because their bomb timer had run out too fast. Three Egyptians, Younes Mohammed Mahmoud, Osama al-Nakhlawi, and Mohammed Jaez Sabbah were sentenced to death in November 2006 for their roles in the blast. Egypt arrested up to 2,400 people following the attacks. The initial investigations by the Israeli and Egyptian governments centered on al-Qaeda, with Israeli
Foreign Minister Silvan Shalom saying "The type, the planning, the scope, the simultaneous attacks in a number of places, all this points to al-Qaeda". However, Egyptian Presidential
Spokesman Majid `Abd al-Fatah later stated that there was no evidence linking the organisation to the attack, instead claiming it was the work of a lone wolf driven by "injustice, aggression and despair" over the
Israeli–Palestinian conflict. ==Aftermath==
