Genocide is an internationally recognized crime. The United Nations defines it as ‘acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group’. The five acts include killing, causing physical or mental harm, inflicting conditions on a group to destroy it, prevent births and forcibly transferring children from one group to another. The term genocide was coined by Polish lawyer Raphäel Lemkin in 1944, partly to name the systematic murder of Jews by the Nazis.
