The Sudanese army shot at a United Nations convoy in war-torn Darfur, severely wounding a driver, in the first attack against the peacekeepers since their mission began this month, the United Nations said Tuesday. The UN issued a sharply worded condemnation of the attack, saying it had protested to the Sudanese government. The statement said the convoy was "clearly marked" as belonging to the joint UN-African Union peacekeeping force, known as UNAMID. "The secretary-general condemns this attack in the strongest possible terms and stresses that ... the government of Sudan has to provide unequivocal guarantees that there will be no recurrence of such activities by its forces," the UN statement said. There was no immediate comment by the Sudanese government.
