Former president Anwar Sadat was assassinated during a military parade on 6 October 1981 by Islamist soldiers angry at Egypt's 1979 peace treaty with Israel.
Egyptians marked on Tuesday the 42th anniversary of the October 6 Arab-Israeli war when Egypt and Syria took advantage of the Jewish Yom Kippur holiday to launch a surprise attack on territories occupied by Israel in previous conflicts.
It ended with a truce that led to the return of Egypt's Sinai Peninsula and a peace treaty between Egypt and Israel in 1979.
