Practice Relating to Rule 146. Reprisals against Protected Persons
Section D. Civilians in the power of the adversary
Belgium’s Law of War Manual (1983), citing several examples of jurisprudence and referring to Articles 4 and 33 of the 1949 Geneva Convention IV, states:
The persons protected by the Geneva Conventions (… civilians) … may not be made the object of reprisals. Therefore, [reprisals] may be directed only against combatants, non-protected property and a restricted group of non-protected civilians.
