Survivors of an airstrike on Jabal al-Uqaydat, an informal gold-mining area in the mountains on the Sudan-Egypt border claimed by both countries, say an aircraft circled overhead before hitting a crowd of some 300 miners; 72 people are believed dead. Rights groups blame the Egyptian air force, and Egypt's military, without addressing the claim directly, said it is running a campaign against illegal mining to assert sovereignty over its territory. Sudan's army leader Abdel Fattah al-Burhan has ordered an investigation, while an adviser called the attack an "unjustified and unacceptable crime"; it follows a June strike at the same site that reportedly killed 23, and highlights how Sudan's war has pushed civilians into dangerous gold work.
