In the context of war, a war crime is a punishable offense under international law, for violations of the laws of war by any person or persons, military or civilian. Every violation of the law of war in an inter-state conflict is a war crime, while violations in internal conflicts are typically limited to the local jurisdiction. In essence, the term "war crime" represents the concept of an international jurisdiction as applicable to the most severe crimes, in areas where government is dysfunctional and society is in a state of turmoil.
