Conflict in Darfur, western Sudan, has displaced over half a million people since March, in addition to 70,000 who have fled across the border to eastern Chad, according to the UN. Figures remain uncertain due to access constraints and poor road conditions, but the latest estimates document at least 300,000 IDPs in northern Darfur, and 126,000 in western Darfur. In southern Darfur 76,000 have been displaced this year, on top of 200,000 who fled north from Bahr el Ghazal between 1988 and 2001.
