South Sudan Conflict Fuels Humanitarian Crisis

People of South Sudan, the world's youngest nation, appear to be hostage to the conflict between rival ethnic groups of President Salva Kiir and his former right-hand man Riek Machar. Violence has killed tens of thousands of people and displaced nearly two million. Many have had to leave their farms and stop producing food. Tribal frictions and adverse weather have affected farming communities outside the war zones. Zlatica Hoke reports.
