Practice Relating to Rule 107. Spies
Section A. Definition of spies
Nigeria’s Manual on the Laws of War states:
Soldiers or civilians acting clandestinely or on false pretences to obtain information about a belligerent with the intention to communicate it to his enemy are engaged in espionage … Soldiers wearing their uniform when penetrating the enemy zone of operations are not spies and if captured, should be treated as prisoners of war.
