Abstract
This research focus on the protection right of children in armed conflict. Some time, children recruited and used in hostilities as a fighter by armed forces or armed groups. For instance, Islamic State in Iraq and Syria (ISIS) has recruited thousands of children to commit international crimes like genocide, war crime and crime against humanity. In addition, the research explains the abusing and trafficking children for sexual purposes. For example, in Iraq ISIS forces raped Yezidy girls and then used in armed conflict. Furthermore, during armed conflict children face refugee and internally displacement. Moreover, the research analyse the effects of armed conflict on children especially when armed forces attack hospitals and schools and kill them. The research tries to answer the questions, why the children are the purpose? What is the responsibility of children when they participate in hostilities? What is the minimum age of children to participate in hostilities? Is it legal to involve children in armed conflict?
