Abstract: "Non-international armed conflicts are not only prevalent today, but are also evolving in terms of the types that have been observed in practice. The article sets out a possible typology and argues that Common Article 3 to the Geneva Conventions may be given an expanded geographical reading as a matter of treaty law. It also suggests that there is a far wider range of rules ? primarily of a binding nature, but also policy- based ? that apply in Common Article 3 armed conflicts with regard to the treatment of persons in enemy hands and the conduct of hostilities"
