The United Nations said it was sending independent rights expert Mashood Adebayo Baderin on a seven-day mission to Sudan.
The visit, which begins Saturday, will be his third. He's leaving for Sudan "to identify areas of technical assistance and capacity building which will help the country fulfill its human rights obligations," the United Nations said.
Baderin said following his February visit he was concerned by the lack of respect for peace in the Darfur region of Sudan.
The United Nations estimates tribal fighting in the Sudanese region of Darfur left as many as 100 people dead and two dozen villages destroyed in early January.
Baderin is expected to travel to Darfur and border state Blue Nile during his visit.
A report published this week by Amnesty International said the Sudanese government may be responsible for war crimes and crimes against humanity for military attacks on civilian villages in Blue Nile state near the border with South Sudan.
AI said the humanitarian situation for people living in the region is "dire."
