The United States and other countries moved to evacuate diplomats and citizens from Sudan over the weekend amid fighting between rival military factions that’s killed at least 420 people and injured over 3,700 more, in a crisis that began on April 15 when the Sudanese military and the paramilitary group known as the Rapid Support Forces began exchanging fire in the capital Khartoum, further dashing hopes of a return of civilian rule in the country. CNN reports the powerful Russian mercenary group Wagner has backed the RSF by providing the paramilitaries with surface-to-air missiles. Wagner founder Yevgeny Prigozhin has denied the report but offered on Friday to act as a mediator between the two warring factions. Meanwhile, many residents remain trapped in Khartoum with dwindling supplies of food, water, medicine and power. For more on the crisis, we speak with Khalid Mustafa Medani, associate professor of political science and Islamic studies who chairs the African Studies Program at McGill University. He says neither side has much support from the civilian population, which has shown an overwhelming commitment to a democratic transition. “It’s not so much a civil war, but essentially a fight to the death between two generals,” says Medani.
