Practice Relating to Rule 65. Perfidy
Section I. Simulation of civilian status
Ecuador’s Naval Manual (1989) states that illegal combatants may be denied prisoner-of-war status, tried and punished. It also states: “It is a violation of the law of armed conflict to kill, injure, or capture the enemy by false indication of … civilian status … Attacking enemy forces while posing as a civilian puts all civilians at hazard. Such acts of perfidy are punishable as war crimes.”
