Quote:
Article 147 of the Fourth Geneva convention defines war crimes as: "Wilful killing, torture or inhuman treatment, including . . . wilfully causing great suffering or serious injury to body or health, unlawful deportation or transfer or unlawful confinement of a protected person, compelling a protected person to serve in the forces of a hostile power, or wilfully depriving a protected person of the rights of fair and regular trial, . . . taking of hostages and extensive destruction and appropriation of property, not justified by military necessity and carried out unlawfully and wantonly."
There is a basic definition of war crimes, open for interpretation I suppose.
