Barefoot and alone, children flee brutal S. Sudan war

South Sudan's civil war has raged on for the past three years with such viciousness that parts of the country are bereft of food and a third of the population has fled their homes, but few refugees present as vexing a problem as children who escape the conflict alone. At the Nguenyyiel refugee camp near Ethiopia's lush western frontier, boys and girls who crossed the border unaccompanied tell tales of murdered families and childhoods shattered by the unremitting violence in South Sudan.
