Two million Syrians have now fled their country’s brutal and escalating civil war, according to the U.N. Half of the refugees are children, the majority of whom have left in the last 12 months. "The war is now well into its third year and Syria is hemorrhaging women, children and men who cross borders often with little more than the clothes on their backs," the U.N. High Commissioner for Refugees said in a statement. Another 4.25 million are displaced inside Syria, making it No. 1 in the world for forcibly displaced citizens. A sad milestone.
