Article 50 in Chapter II: "Civilians and Civilian Population" of Protocol I Additional to the Geneva Conventions defines that a civilian is not a privileged combatant. Article 51 describes the protection that must be given to civilians (unless they are unprivileged combatants) and civilian populations. Chapter III of Protocol I regulates the targeting of civilian objects. Article 8(2)(b)(i) of the Rome Statute of the International Criminal Court also prohibits attacks directed against civilians. Not all states have ratified Protocol I or the Rome Statute, but it is an accepted principle of international humanitarian law that the direct targeting of civilians is a breach of the customary laws of war and is binding on all belligerents.
