[JURIST] Nageh Ibrahim and Fouad el-Dawalibi, founding members of militant Egyptian Islamic movement al-Gamma al-Islamiyya [Wikipedia backgrounder], have been released after more than two decades in prison in connection with the killing of President Anwar Sadat [CNN profile] during a military parade in Cairo on Oct. 6, 1981. The men were convicted for their connections to Sadat's assassination and were sentenced in 1984, Ibrahim to 24 years and el-Dawalibi to 15 years, though Egyptian law allows people to be held after their sentences are completed. It is thought the men were freed due to a truce reached between al-Gamaa al-Islamiyya and the Egyptian government. Two primary al-Gamaa al-Islamiyya leaders, Assem Abdel Maged and Essam Derbala remain in prison in connection with Sadat's assassination, but a fifth convicted assassin, Tarek el-Zomor, was released from prison [JURIST report] earlier this year after serving more than his designated sentence of 22 years. AP has more.
