Herve Ladsous, head of the UN Department of Peacekeeping Operations, has condemned an alliance between rebel groups from Darfur, South Kordofan and Blue Nile, calling it "counter-productive"
The UN has called for an official inquiry into the bombing of a South Sudan refugee camp.
Ladsous made the comments in an effort to calm the political situation in the region, which is tense following the bombing of a refugee camp in South Sudan by Sudan government forces. The most recent conflict in South Kordofan and Blue Nile erupted in June of this year and has continued since; violence is once again occurring in Darfur and with South Sudan claiming it is ready for a war with Sudan, the situation is extremely fragile.
Ladsous stressed the need for calm and warned against any moves by leading political figures which could spark more violence.
He was referring to the alliance announced last week by rebel leaders in the troubled east and south regions of Sudan, who called for the government of Omar Al-Bashir to be overthrown and replaced with a "democratic regime"
