UNITED NATIONS (AFP) - More than 100 people have died in battles for control of gold mines in Sudan’s conflict-ravaged Darfur region, the UN said Wednesday. Several North Darfur villages have been torched in the battles between rival tribes this month, and gunmen have blocked roads to prevent UN observers from getting to the region, UN spokesman Martin Nesirky told reporters. Battles between tribes have added to a resurgence in violence in Darfur, where the Khartoum government has been battling an uprising for the past decade. The UN says more than 300,000 people have died since 2003.
