Practice Relating to Rule 7. The Principle of Distinction between Civilian Objects and Military Objectives
Section A. The principle of distinction
In its written statement submitted to the ICJ in the Nuclear Weapons case in 1995, Egypt invoked the requirement to “distinguish between … civilian objects and military objectives”. 
Egypt, Written statement submitted to the ICJ, Nuclear Weapons case, 20 June 1995, § 17.
The Report on the Practice of Egypt states that Egypt recognizes the obligation to distinguish between civilian objects and military objectives. It further notes that the principle of distinction between civilian objects and military objectives is said to be well established in Egypt’s practice and opinio juris and is thus considered to be a customary rule of IHL.
