Solution:Communal violence, although a serious domestic crime, is not classified as an international crime under international criminal law. International crimes include genocide, crimes against humanity, war crimes, aggression, torture, and human trafficking.
These crimes fall under the jurisdiction of international bodies such as the International Criminal Court (ICC) and are defined in treaties like the Rome Statute (1998). Communal violence, however, is dealt with largely under national criminal laws, unless it rises to the level of systematic persecution meeting criteria for crimes against humanity.
Therefore, among the given options, communal violence is not recognized as an international crime.
