Sudan's army chief and de facto leader, Abdel Fattah al-Burhan, has ordered an investigation into a Saturday airstrike on the Jabal al-Uqaydat gold mining area near the Egyptian border, which a rights group, the Emergency Lawyers, says killed 72 people and blames on Egypt. AFP could not verify the claim and Egypt has not commented officially, though its foreign minister spoke with his Sudanese counterpart and stressed respect for each country's territorial integrity. The incident matters because Egypt, a close ally of Burhan, is wary of Sudan's war spilling across their shared border, and a reported Egyptian strike on the same mine in June killed 23 workers; the frontier region includes the disputed Halayeb Triangle, a resource-rich area claimed by both countries.
