International humanitarian law distinguishes between combatants and civilians in armed conflicts, to the extent that an intentional attack against civilians or against civilians not taking part in the hostilities constitutes a war crime. Civilians in armed conflicts must be protected from harm caused by attacks by armed groups, states or individuals, because they have the right to be protected from any harm resulting from the failure of states to comply with legal standards during armed conflicts. In the event of negligence on the part of states and their failure to comply with the rules of international humanitarian law in armed conflicts, legal responsibility is imposed on them, and in this case, when damage occurs, all perpetrators and those responsible for causing damage to civilians during armed conflicts must be held accountable and compensate for the damage. This article, using a descriptive-analytical method, seeks to answer the main question: What is the responsibility of states for violations of international humanitarian law against civilians in armed conflicts? The main hypothesis is that despite the rules of civilian rights in conflict zones based on international humanitarian law, we still witness the occurrence of damage and an unsafe environment for civilians in armed conflicts of the involved states, which doubles the importance of the legal and international responsibility of states in adhering to humanitarian principles during armed conflicts.
