This publication is an outcome of the training sessions organized by the International Bureau for Children’s’ Rights (IBCR) for the members of the International Tribunal for Children’s Rights (ITCR) in September 2001 in Sarajevo, Bosnia, and Herzegovina. The training materials compiled and presented by Ms. Rachel Harvey from the Children and Armed Conflict Unit (a joint project of the Children’s Legal Centre, an independent charity, and the Human Rights Centre of the University of Essex) were updated later on to reflect upon major aspects of international humanitarian and human rights law relating to children affected by armed conflict. This publication does not intent to cover all aspects of the subject. Instead it aims at serving as a quick reference manual for those involved in researching, promoting and protecting the rights of children affected by armed conflict.
