Egyptian Islamic Jihad (a.k.a. "Al-Gamaa Al-Islamiyya") is a militant Egyptian Islamist movement dedicated to the establishment of an Islamic state in Egypt. The group was formed in 1980 as an umbrella organization for militant student groups which were formed after the leadership of the Muslim Brotherhood renounced violence. It is led by Omar Abdel-Rahman, who has been accused of participation in the 1993 World Trade Center bombing. In 1981, the group assassinated Egyptian president Anwar Sadat. On November 17, 1997, in what became known as the Luxor massacre, it attacked tourists at the Temple of Hatshepsut (Deir el-Bahri); six men dressed as police officers machine-gunned 58 Japanese and European vacationers and four Egyptians.
