Practice Relating to Rule 146. Reprisals against Protected Persons
Section D. Civilians in the power of the adversary
In its written comments on other written statements concerning the Nuclear Weapons case before the ICJ in 1995, Egypt stated:
Reprisals are prohibited against protected persons and objects according to the Geneva Conventions of 1949 and their additional Protocols. This prohibition of reprisal is absolute and applies to the use of all weapons. In consequence, the protected persons and objects can never become targets of any attack, including nuclear attacks. The provisions of the Conventions and the Protocols carrying this prohibition of reprisals against protected persons and objects are considered declaratory of customary law.
