Future of a generation 'on brink' as 1m children flee South Sudan's civil war

"The horrifying fact that nearly one in five children in South Sudan has been forced to flee their home illustrates how devastating this conflict has been for the country's most vulnerable."

More than one million children have fled South Sudan's civil war amid the world's fastest growing refugee crisis, two United Nations agencies said.

Another one million South Sudanese children are displaced within the country, having fled their homes due to the civil war, according to the UN's child and refugee agencies.
