Half of Syria's refugees are children with many left orphaned by the country's three year civil war, a new UN report has found.
UN High Commissioner for Refugees Antonio Guterres said many children have been traumatised by the violence.
Mr Guterres warned that Syria faces the risk of a "lost generation" if something is not done to help ease the heavy toll of the conflict.
