This article addresses the question of whether the violence between Türkiye and the Kurdistan Worker’s Party (PKK) constitutes an armed conflict within the meaning of international humanitarian law. The article first explains the different non-international armed conflict descriptions provided by (i) the ICTY’s famous Tadić decision, (ii) Additional Protocol II, and (iii) the Rome Statute of the ICC and discusses the different applicability thresholds set by these sources. After noting that the terrorist nature of the acts of violence in a situation will not prevent them from being characterized as an armed conflict and that the application of the international humanitarian law norms would not in fact affect the legal status of the PKK, this article examines whether Türkiye’s struggle against the PKK could be classified as an armed conflict subject to international humanitarian law norms.
