The International Criminal Court (ICC or ICCt) is an intergovernmental organization and international tribunal that sits in The Hague, Netherlands. The ICC has jurisdiction to prosecute individuals for the international crimes of genocide, crimes against humanity, war crimes, and the crime of aggression. It is intended to complement existing national judicial systems and it may therefore exercise its jurisdiction only when certain conditions are met, such as when national courts are unwilling or unable to prosecute criminals or when the United Nations Security Council or individual states refer situations to the Court.
