Damascus. The war in Syria is creating a generation of damaged children, a UN report warns.School-age refugees who have fled to neighbouring countries are increasingly cut off from education and forced to work to survive, the study found.As many as 300,000 living in Lebanon and Jordan could be without schooling by the end of 2013, the UNHCR says.Many of those not at school go out to work for long hours and for low pay from as young as seven years old.More than half of 2.2 million Syrian refugees are children, the UN says, with many facing grave dangers even outside the war zone.Those perils include threats to their physical and psychological well-being, according to the report’s authors. Launching the report, UN High Commissioner for Refugees Antonio Guterres said: "If we do not act quickly, a generation of innocents will become lasting casualties of an appalling war.”The study is the latest to attempt to illustrate the heavy toll of Syria’s three-year-old civil conflict on children both inside and outside its borders.It comes shortly after an estimate from a London-based think-tank put the number of children killed during Syria’s civil war at more than 11,000. The UNHCR carried out a series of interviews with Syrian children and families living in Jordan and Lebanon between July and October 2013.Researchers interviewed 81 refugee children and held group discussions with 121 others in Jordan and Lebanon, and consulted UN and NGO staff working with those communities. They found high levels of child recruitment, labour and loneliness among children living in displaced families.
