Military sources have told the Egyptian daily al-Masry al-Youm Egypt's Supreme Military Court will hear the appeal of Mohamed al-Zawahiri who was tried in absentia in a case involving Islamists who fought against the Soviets in the Balkans.
Egyptian authorities charged the returning fighters with plotting a coup, murdering civilians and targeting tourists and Christians.
Mohamed al-Zawahiri was released in March as part of a government effort to free Islamist prisoners who were detained in political cases.
Zawahiri was arrested three days later when authorities learned of his earlier conviction.
