(ICRC) – The main sources of international humanitarian law (IHL) are international treaty and customary law. In addition, domestic traditional law can improve the protection of victims of armed conflict. The ICRC’s online Customary IHL Database was recently updated with the practice of five additional countries: Denmark, Djibouti, Poland, Tajikistan and Somalia. Omar Odeh, deputy head of the ICRC’s delegation in Somalia, explains the importance of such traditional law.
