More Than 80 People Killed in West Darfur Attack Nabeel Biajo WASHINGTON - United Nations Secretary-General Antonio Guterres has called on authorities to protect citizens in Sudan's West Darfur after unknown armed men killed more than 80 people andinjured at least 160 others in theKrindingrefugee camp and elsewhere in Genena, the capital of Sudan's West Darfur state,prompting the governor to declare a state of emergency. Governor Mohamed Abdallah Al Douma also deployed hundreds of troops across the state to restore security. A statement issued by Guterres' spokesperson said the head of the world body "expresses his deepest condolences to the bereaved families and wishes a speedy recovery to the injured." The trouble began Friday when a member of the Masalit tribe killed a member of an Arab tribe in a personal dispute, Douma said. He said the killer was arrested and the state public prosecutor opened an investigation into what happened. EarlySaturdaymorning, armed men from different parts of Darfur planned and launched what appeared to be revenge attacks, Douma said. "And I see no reason for attacking the camp because--I don't know if the killer is from this camp or not, but even if he is, it was an individual act," Douma told South Sudan in Focus."But they burned down more than a third of the camp and killeda number ofpeople that we are still counting." Thousands ofinternally displaced persons fledthe campbecause ofthe violence. Douma saidthe attackers also looted property. .
