Sudan's army said on Sunday it had seized back control of the town of el-Gitaina, just south of the capital, from the Rapid Support Forces (RSF) and broken the paramilitary group's siege on the strategic city of el-Obeid to the west.

Activists said three days of attacks by the paramilitary group had killed more than 200 people in White Nile state, which has emerged as a key battleground as the army regains territory.

The Sudanese army said on Sunday it had broken a nearly two-year siege imposed by the Rapid Support Forces (RSF) on El Obeid, capital of North Kordofan state, linking its forces advancing from White Nile state with those already stationed inside the city.

Sudan's army and allied groups could face formidable battlefield challenges if the recent political agreement between the paramilitary Rapid Support Forces (RSF) and a powerful faction of a southern rebel group becomes a military alliance,
