In a special edition of HARDtalk broadcast live from London, as part of the BBC’s Freedom Season, Zeinab Badawi speaks to the acclaimed South Sudanese singer and political activist, Emmanuel Jal. He was captured and forced to fight as a child soldier during the Sudanese civil war. His country South Sudan - the world's newest nation - may now be independent but it has descended into vicious ethnic fighting. What lies behind this new wave of conflict and how can it be stopped?
