This report from the UN Office of the SRSG on Violence against Children explores repatriation, rehabilitation, and reintegration of the tens of thousands of foreign, Iraqi and Syrian children who are being held in detention on suspected ISIS association or terror-related offenses, or in camps. The report notes that these children are exposed to violence, due process violations (e.g. lack of hearings and legal representation) and family separation. Separated from their families, these children are deprived of knowing their family relations and are at risk of statelessness. In situations where children have been illegally recruited by violent extremist groups, the report notes that priority should be given to repatriation mechanisms that ensure that their best interests are paramount.
