The number of registered child refugees fleeing Syria's violence has topped the 1 million mark in another grim milestone of the deepening conflict, two U.N. agencies said Friday. Roughly half of all the nearly 2 million registered refugees from Syria are children, and some 740,000 of those are under the age of 11, according to the U.N. refugee and children's agencies. "This one millionth child refugee is not just another number," said Anthony Lake, the head of UNICEF, the U.N. children's agency. "This is a real child ripped from home, maybe even from a family, facing horrors we can only begin to comprehend." The children's ordeals are not over once they escape Syria, said Antonio Guterres, the head of the Office for the U.N. High Commissioner for Refugees, known as UNHCR.
