RIYADH: As Sudan’s devastating conflict approaches its third anniversary, the army announced on Tuesday that it has broken the years-long siege on Kadugli, the famine-stricken capital of South Kordofan, in what analysts say could signal a shift in the war’s momentum. The army’s breakthrough, announced days after a similar advance in nearby Dilling, offered South Kordofan residents a reprieve from a deepening humanitarian crisis that had triggered mass displacement and widespread hunger, sparking hopes that aid could finally resume.
