Home > War crimes

These are particularly serious violations [1] of IHL, endangering protected persons [2] and/or objects [3], or breaching important international values, for which the individual criminal responsibility [4] of perpetrators may be engaged. War crimes can be committed in both international and non-international armed conflicts, although the list of possible war crimes is not identical for both types of conflicts.

The Geneva Conventions and Additional Protocol I establish that certain violations of IHL are to be considered “grave breaches [5]”, and they must be prosecuted by High Contracting Parties on the basis of the principle of universal jurisdiction [6]. Other serious violations of IHL are established by customary international law and by international criminal law [7] treaties. Such serious violations of IHL, together with grave breaches, constitute war crimes.

War crimes constitute one category of “international crimes”, the others being genocide [8] and crimes against humanity [9].

See Breach [10], Violations [1]; Individual criminal responsibility [4]; Genocide [8]; Crimes Against Humanity [9]; International Criminal Court [11]; ICTY [12]; ICTR [13]; International criminal law [7]; Individual criminal responsibility [4];
