ISMAILIA, Egypt: An Egyptian who blew himself up in an attack on a multinational force in the Sinai Peninsula was a 19-year-old student of Islam at a Cairo university, security sources said on Saturday. Eid Salman Mohammed Salim launched his suicide attack on April 26 on vehicles used by the Multinational Force and Observers. There were no MFO casualties. The MFO observes the implementation of Egypt s 1979 peace treaty with Israel in the Sinai. Salim s father had identified his son s head at a morgue in El Arish, a town in northern Sinai where his family lived. Salim was a student of Islam at Al-Azhar University in Cairo. Eid came from his university on the morning of the incident, left his identity card and papers at home, and told his father that he was heading to work. Then he disappeared, one security source said. Salim was a relative of two men wanted in April 24 bombings in the Red Sea resort of Dahab, which killed 19, the sources said. The suspects, Salman Salim El-Zayout and Salim Atta, were killed in clashes with the police in Sinai on Sunday. DNA tests were being conducted to identify the remains of a man who carried out a second suicide attack on April 26 near a police station, the sources said. Nobody was wounded in that attack. Security sources are blaming a series of attacks in Sinai since October 2004 on a group called Tawhid wal Jihad, which was also the name of Abu Musab Al-Zarqawi s militant group before it began calling itself Al-Qaeda Organization for Holy War in Iraq. Including the Dahab bombs, the Sinai attacks have killed at least 117 people. The Red Sea resort of Taba and beach camps further south were bombed in October 2004 and Sharm El-Sheikh was hit in July 2005. Men identified by the authorities as members of the group have come mainly from El Arish, which is a poor town on the Mediterranean coast. Reuters
