South Sudan violence halts oil production

(FILES)-- A file photo taken on April 23, 2012 shows a view of an oil field in Bentiu, South Sudan. South Sudan restarted oil production on April 6, 2013, ending a 15-month bitter row with former civil war foe Sudan and marking a major breakthrough in relations after bloody border clashes last year. "The oil is now flowing, " South Sudan oil minister Stephen Dhieu Dau shouted as he flicked a switch to restart production at a ceremony in the Thar Jath field in Unity state.
