The funeral service for Egyptian military officer Baki Zaki Youssef, who is considered by Egyptians to be a hero of the 1973 war against Israel, was held at St. Mark's Coptic Orthodox Church in Cairo on Sunday.
Youssef died on Saturday at the age of 88.
The funeral service was attended by a number of current and former state officials and top level army officers.
Youssef was widely known as the brains behind the engineering plan which led to the fall of the Bar Lev defensive sand wall, which in turn led the Egyptian army to victory in October 1973.
The 100 km fortification was built by Israel on the eastern side of the Suez Canal after the 1967 war and was believed to form an "invincible wall" which would prevent the Egyptian army from crossing the Suez Canal to liberate Sinai from Israeli occupation.
Youssef came up with the idea of using powerful water jets to break through the sand wall, and the technique was deployed with success.
The Egyptian cabinet issued a statement on Saturday describing him as “an icon of pride and honour” for all Egyptians.
