Today, leaders from Sudan and South Sudan met in Ethiopia in an effort to resolve issues that have led to renewed fighting, stalled oil production and the displacement of tens of thousands of people. Relations between the two countries have been tense since South Sudan gained independence in 2011. Both countries signed a deal in September to pull back military from a disputed border region, but attacks continued, according to the governments of both sides. Local residents also continue to face violence and military conflict in South Kordofan, Darfur and Blue Nile. For more on the talks today, we go to Khartoum to speak with Munzoul Assal, associate professor of Social Anthropology at the University of Khartoum. He joins us via Skype.
