It’s one of Africa’s most bitter, if often forgotten, conflicts.

In 2011, South Sudan gained independence from Sudan following a 2005 peace deal that ended Africa’s longest-running civil war.

After a referendum, in which an overwhelming majority of South Sudanese voted to secede, Africa’s newest country came into being, the first since Eritrea split from Ethiopia in 1993.

But two Sudanese provinces, South Kordofan and Blue Nile, the people of which predominantly wanted to become citizens of the new nation, were excluded from the deal.

The SPLM-N, the northern affiliate of Sudan’s People’s Liberation Movement (SPLM) in South Sudan, consequently took up arms against the Sudanese government of President Omar al-Bashir, and fighting has continued on and off ever since.

Five years ago, as the war got under way, People and Power sent reporter Callum Macrae to investigate allegations of war crimes committed by the Bashir regime in the region. Last month he went back.
