A war crime is a violation of the laws of war that gives rise to individual criminal responsibility for actions by combatants in action, such as intentionally killing civilians or intentionally killing prisoners of war, torture, taking hostages, unnecessarily destroying civilian property, deception by perfidy, wartime sexual violence, pillaging, and for any individual that is part of the command structure who orders any attempt to committing mass killings including genocide or ethnic cleansing, the granting of no quarter despite surrender, the conscription of children in the military and flouting the legal distinctions of proportionality and military necessity.
Crimes against humanity are certain serious crimes committed as part of a large-scale attack against civilians. Unlike war crimes, crimes against humanity can be committed during both peace and war and against a state's own nationals as well as foreign nationals. Together with war crimes, genocide, and the crime of aggression, crimes against humanity are one of the core crimes of international criminal law and, like other crimes against international law, have no temporal or jurisdictional limitations on prosecution.
The Rome Statute of the International Criminal Court is the treaty that established the International Criminal Court (ICC).

In the practice of international law, command responsibility is the legal doctrine of hierarchical accountability for war crimes, whereby a commanding officer (military) and a superior officer (civil) is legally responsible for the war crimes and the crimes against humanity committed by his subordinates; thus, a commanding officer always is accountable for the acts of commission and the acts of omission of his soldiers.
