The ICC has jurisdiction over four core international crimes:

Genocide: Acts committed with intent to destroy, in whole or in part, a national, ethnic, racial, or religious group.

Crimes Against Humanity: Widespread or systematic attacks directed against civilians, including murder, enslavement, torture, and other inhumane acts.

War Crimes: Serious violations of the laws and customs of war, including targeting civilians, attacking humanitarian personnel, or using prohibited weapons.

Crime of Aggression: The planning, preparation, initiation, or execution of acts of armed force by one state against another in violation of the United Nations Charter.

Further details are outlined in the ICC's Elements of Crimes, which defines the specific acts that constitute each crime and the legal elements required for prosecution.
