Conflict and bloodshed in Sudan are not limited to the Darfur region — separate crises are flaring in the north, the south and in the central Nuba Mountains.

Worldfocus.org’s weekly radio show explores tensions in South Sudan, the site of a two-decade civil war between the Muslim north and mostly Christian south that killed more than 1.5 million people. The south is also home to 80 percent of Sudan’s oil.

The war came to an end in 2005 with the signing of a peace agreement that exempted the south from Islamic Sharia law and established a regional southern government as well as a system of shared oil revenues. But with increasingly deadly tribal violence in South Sudan and a humanitarian crisis that could soon eclipse that in Darfur, trouble is brewing once more.

In a conference on Sudan in Washington last week, leaders from the north and south pledged to avoid a return to war.

South Sudan is set for a referendum on independence in 2011 and many in the region hope that the vote will allow a break from Khartoum once and for all, creating a new African nation. Others remain wary, pointing to corruption and incompetence on the part of South Sudan’s government and accusing leaders of squandering oil revenues.
