Practice Relating to Rule 65. Perfidy
Section A. General
During the Algerian war of independence, the use by Algerian combatants of perfidious methods of warfare was prohibited. Perfidy was understood to mean methods that aggravated suffering without having a direct effect on the issue of the struggle. The Report on the Practice of Algeria notes, however, that there were instances in which acts considered to be perfidious were committed, but it concludes that such acts were rare and that they did not affect a general line of conduct of proscribing perfidy.
