One of the most interesting and practical phases of the international responsibility of the state is its responsibility for injuries sustained by aliens during civil war. Injuries sustained in actual belligerent operations are not usually compensated, on the principle of non-liability for war damages. The importance of a separate discussion of injuries sustained during civil war arises out of the legal position which may be attributed to insurgents and the resultant liability of the state for injuries committed by them. The difficulty of the subject is also enhanced by the fact that the practice of states has differed to some extent in the application of such rules as we may consider to govern the subject.
