Practice Relating to Rule 65. Perfidy
Section B. Killing, injuring or capturing an adversary by resort to perfidy
Sweden’s IHL Manual (1991) affirms: “Under the provisions of the [1907 Hague Regulations] it is prohibited to kill or injure an enemy by resort to perfidy.”
Under Sweden’s Penal Code (1962), as amended in 1998, “the killing or injuring of an opponent by means of some … form of treacherous behaviour” constitutes a crime against international law.
