Sudan faces the world’s largest humanitarian crisis after more than two years of war between rival forces. The Sudanese Armed Forces (SAF), led by Abdel-Fattah Burhan, and the Rapid Support Forces (RSF), headed by Mohammed Hamdan Dagalo, fight for control. Both sides are accused of atrocities, while foreign powers allegedly supply weapons. UN calls for a ceasefire and an arms embargo have failed as the conflict deepens.
