Sudan's military leader, Abdel Fattah al-Burhan, said on Tuesday that the army would reclaim "every inch" of land held by the paramilitary Rapid Support Forces (RSF) and that the "military option" would continue, rejecting negotiations to end a war that began in April 2023 and has displaced about 13 million people. His vow came as fighting spread, with at least 10 civilians reported killed in an RSF attack in West Kordofan state and more than 5,500 people displaced in Blue Nile state over three days, according to a local charity and the International Organization for Migration. A US envoy has urged a Sudanese-led national dialogue and a transition to civilian rule, but the stance of the army chief leaves little prospect of a near-term ceasefire.
