Since the outbreak of the armed conflict in Yemen in late 2014, Mwatana for Human Rights has documented hundreds of incidents in which children under the age of 18 were recruited. All conflicting parties in various governorates of Yemen have excessively recruited and used children as soldiers, as documented by Mwatana for Human Rights during the process of monitoring these types of violations since the beginning of the conflict. By child recruitment and use, we mean the recruitment and use of children under 18 years of age, whether boys or girls, by an armed military group as front-line fighters, in security missions, as cooks, porters, moles, or for logistical and sexual purposes. The recruitment and use of children by parties to the conflict is one of the six grave violations against children.
