UN report warns that the war in Syria is creating a generation of damaged children, cutting off School-age refugees who have fled to neighboring countries from education and forced to work to survive.

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."

According to UNHR report, as many as 300,000 living in Lebanon and Jordan could be without schooling by the end of 2013.

It also stated that many of those not at school go out to work for long hours and for low pay from as young as seven years old.

UN also reported that more than half of 2.2 million Syrian refugees are children, with many facing grave dangers even outside the war zone, listing those perils to include threats to their physical and psychological well-being.

The report however 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.
