Law of Armed Conflict: Principles and Concepts is a book that sets out to disseminate, promote and strengthen the knowledge of International Humanitarian Law (IHL) amongst students, scholars, legal practitioners, State and Non-State armed groups, media practitioners and other groups interested in the protection of humanity during armed conflict. As a consequence of the growing complexity of modern armed conflict, this book contains materials that espouse the elements of law which are geared towards the protection of victims of armed conflict. It also presents contemporary issues relating to IHL in a clear, concise, accessible, practical and comprehensive manner. The main goal of the book is to show that IHL remains relevant in contemporary practice and that it provides answers to armed conflict related issues and challenges. Its distinctive style and format makes it the ideal everyday companion for anyone approaching IHL for the first time and who is interested in armed conflict-related issues. As a result of the structure and contents of the book, a military reader will also find what will be of use to him. Importantly, students, scholars, legal practitioners and in fact, the general public in Nigeria will find knowledge and pleasure in the topics relating to the armed conflict in the Northeast Nigeria and the degree of compliance with the rules and principles of the law of armed conflict.
