(OSRSG-CAAC) – In his Annual report on children and armed conflict covering the year 2015, the UN Secretary-General expressed his shock at the scale of grave violations committed against children in countries such as Afghanistan, Iraq, Somalia, South Sudan, Syria and Yemen. Emerging and escalating crises had a horrific impact on boys and girls. The situation in Yemen was particularly worrisome with a five-fold increase in the number of children recruited and six times more children killed and maimed compared to 2014. Violations committed by the Islamic State of Iraq and the Levant (ISIL) continued to have a devastating impact on children, including persistent child recruitment and use and boys featured as child soldiers in social media and in some cases as executioners. In Nigeria, Boko Haram increased suicide attacks, including by using 21 girls as suicide bombers in crowded public spaces. The armed group spread its activities from northeastern Nigeria to neighboring countries, causing a significant number of casualties among civilians and large-scale displacements.
