While armed conflicts are principally governed by international humanitarian law (IHL), activities of members of non-State armed groups and their affiliates may also qualify as terrorist offences. After explaining why the concurrent application of IHL and criminal law instruments on terrorism causes friction, this article analyzes the chief mechanism for dissipating this friction: a clause excluding activities governed by IHL from the scope of criminal law instruments on terrorism. Such armed conflict exclusion clauses exist at the international, regional and national level. This article explains how an exclusion clause can best avoid friction between IHL and criminal law instruments on terrorism.

恐怖主义罪行和国际人道法：武装冲突排除条款

虽然武装冲突主要受国际人道法 (IHL) 管辖，但非国家武装团体成员及其附属机构的活动也可能被视为恐怖主义罪行。在解释了国际人道法和反恐刑法文书同时适用的原因后，本文分析了消除这种摩擦的主要机制：将国际人道法管辖的活动排除在反恐刑法文书范围之外的条款。此类武装冲突排除条款存在于国际、区域和国家层面。本文解释了排除条款如何能最好地避免国际人道法与有关恐怖主义的刑法文书之间的摩擦。
