Heavy firing has broken out in Sudan's capital, forcing the US ambassador to shelter as Sudan's powerful paramilitary group have seized control of the presidential palace and airport.
Clashes erupted early today between the Sudanese army and the paramilitary Rapid Support Forces (RSF), just weeks after mounting tensions between the groups.
United Nations officials and foreign diplomats have tried and failed in recent days to prevent the tensions from turning violent, but many now fear a civil war is on the horizon.
