Who is a combatant under IHL and what does their ‘privilege’ consist of? Who is a prisoner of war (“POW”) and how should they be treated? Do ‘terrorists’ belong to a different category? Do such categories equally apply in international and non-international armed conflicts?

In a generic sense, combatants are members of the fighting forces of the belligerent parties to an international armed conflict. The main feature of their status is that they have the right to directly participate in hostilities (‘combatant privilege’). Nevertheless, they must respect IHL and thus be punished, should they commit violations.

In addition to having the right to participate in hostilities, combatants are entitled to POW status, if they fall into enemy hands during an international armed conflict. Among other measures aimed at ensuring they are well treated, this protective status entails that they may not be prosecuted for their mere participation in hostilities. If, however, they did not distinguish themselves from the civilian population when captured, they can lose POW status and also be tried for acts of war. POWs can be held by the enemy until the cessation of active hostilities without any particular procedure, the purpose of their internment being to prevent their further participation in the conflict in support of the enemy.

During their internment, POWs must be treated humanely and must be protected against intimidation, insults and public curiosity. The 1949 Third Geneva Convention relative to the treatment of POWs (“GCIII”) also details conditions of internment covering issues such as accommodation, food, clothing, hygiene and medical care. The ICRC’s updated Commentary on GCIII (2020) bring fresh insights on the continued relevance of such essential protections (e.g. humane treatment of POWs, protection of their persons and honor,  obligation to release and repatriate them), reflecting changes  in the interpretation of concepts like the respect granted to women, mental health and disability, as well as developments relating to medical ethics and data-protection standards.

In the context of fighting international terrorism, persons who never had combatant status or lost their POW status, but nevertheless directly participated in hostilities, are sometimes labelled as ‘terrorists’, ‘foreign fighters’, ‘unprivileged combatants’ or as ‘unlawful combatants’. While such terms do not exist in IHL, and hence do not bear any legal meaning or consequence, the status and treatment of persons designated as such has given rise to considerable controversy. What is certain, however, is that any person detained in relation to an armed conflict, be it a POW or a civilian having taken a direct part in hostilities, be it someone labelled as ‘terrorist’ or any other non-legal term, is entitled to be treated humanely and benefits from related fundamental guarantees under both treaty and customary IHL.
