Fighting flares in South Darfur amid fears of new civil war

The conflict has brought daily battles to the streets of the capital of Khartoum, a revival of ethnically targeted attacks in West Darfur, and the displacement of more than 4 million people within Sudan and across its borders into Chad, Egypt, South Sudan and other countries. Clashes between the Sudanese army and paramilitary Rapid Support Forces have flared periodically in Nyala, the country's second biggest city and a strategic hub for the fragile Darfur region.
