UN High Commissioner for Refugees Antonio Guterrers speaks with Edie Lush at Hub Davos. He sheds light on the terrifying situation in Southern Sudan, the world's newest country, where there is a dramatic humanitarian crisis. People are fleeing to South Sudan from fighting in the north, there is inter-ethnic conflict, looting, burning, raping, stealing cattle. There is no infrastructure, no economy, and there are hundreds of thousands of refugees descending in the country.
