The haunting cries of five-year-old Rawan Alowsh, pulled alive from rubble in Aleppo by her ponytail, have reminded the world once again that behind the politics of Syria’s civil war are millions of vulnerable children. Government air strikes in recent days have pounded rebel-held areas of Aleppo, where more than 250,000 civilians are trapped. Britain’s permanent representative to the UN said the attacks had “unleashed a new hell on Aleppo”, which he described as war crimes. In the middle of the conflict there are at least 100,000 children, aid agencies estimate. Save the Children warned that approximately half the casualties being treated in eastern Aleppo were children. It said injured children were dying on the floors of hospitals due to shortages of equipment and medicines.
