The United States has slapped Sudan’s army chief, Abdel Fattah al-Burhan, with a sanction, accusing him of choosing war over negotiations. The US said that al-Burhan has thwarted every effort to bring an end to the conflict that has killed tens of thousands of people and driven millions from their homes.

Sudan's army chief has ordered an investigation into allegations that his troops carried out widespread atrocities after recapturing the capital of Gezira state from their paramilitary rivals. Gen Abdel Fattah al-Burhan's move comes after widespread concern that civilians - including foreign nationals - were killed after the seizure of Wad Madani.
