Crimes Against Humanity
A crime against humanity is a serious criminal act committed within the context of a “widespread and systematic attack directed against a civilian population”. A crime against humanity can can occur during war or peace, and can include murder, rape, slavery, persecution, extermination, and torture.
War crimes are serious criminal acts committed within the context of an “armed conflict”: a resort to armed force between states. They can also be committed in a civil war. The criminal act must be related to the armed conflict, so a murder or a theft during a war but unrelated to the war is not a “war crime”. A war crime can be many different things, from illegal seizure of property to attacking civilian objects to using prohibited gases.
Genocide is an act committed with the intent to destroy in whole or in part a national, ethnic, racial, or religious group. It can include killing or causing serious bodily or mental harm to members of the group. It can also include deliberately inflicting on the group conditions of life calculated to bring about its physical destruction, or imposing measures to prevent births. Genocide can happen during war or peace.
