Egypt's President Abdel-Fattah El-Sisi commemorated the 36th anniversary of the Sinai Liberation Day by laying a wreath at the Memorial of the Unknown Soldier in Nasr City, Cairo on Tuesday. The president also paid his respects at the tomb of late Egyptian President Anwar El-Sadat, who led the 1973 October War for the liberation of Sinai from Israeli occupation. President El-Sisi was received at the memorial by the Minister of Defence Sedki Sobhy, Armed Forces Chief of Staff Mohamed Farid and a number of military commanders. On 25 April, Egypt celebrates the completion of the withdrawal of all Israeli military forces from the Sinai Peninsula in 1982, following the 1979 Egyptian-Israeli peace treaty. Sinai Liberation Day is an official holiday in Egypt.
