"Children who have seen scenes no child should ever see have been wounded physically or psychologically, and with every day the fighting drags on, these children are at risk of losing their future forever," UN High Commissioner for Refugees Antonio Guterres told the UN General Assembly Tuesday. He urged the international community to support Syria’s neighbors who have taken in nearly 2.5 million refugees. Another 6.5 million Syrians are displaced in their own country and 200,000 are under siege, denied food, water and medical supplies for month after month.
