All four atrocity crimes - genocide, crimes against humanity, war crimes, and ethnic cleansing - can be considered as crimes against humanity or war crimes, depending on the circumstances in which they are committed. For example, genocide is specifically defined as a crime against humanity in international law, while war crimes can encompass a range of acts committed during armed conflict that violate international humanitarian law. Ethnic cleansing can also be considered a crime against humanity if it involves widespread or systematic attacks against a civilian population based on their ethnicity or nationality. Ultimately, the classification of a particular atrocity crime as a crime against humanity or war crime will depend on the specific legal framework involved and the context in which the crime occurred.
