Practice Relating to Rule 156. Definition of War Crimes
Sweden’s IHL Manual (1991), in a provision dealing with penal responsibility for violations of IHL, states:
The Conventions distinguish between grave breaches and other transgressions. A grave breach in the meaning of the conventions exists where the breach has been directed at persons or property protected by the conventions and has also included any of certain specially listed acts.
