Rebels ambushed Sudanese troops and Sudan's military bombed and destroyed eight villages in Darfur, officials said Wednesday, detailing the latest reported violations of a largely ignored cease-fire in the western region of Sudan. The rebel ambush reportedly took place on Tuesday in Graida, a town about 100 kilometers south of Nyala, the capital of South Darfur state, one of the three states that make up Darfur, a region roughly the size of France, said Ahmat Allam-mi, a member of a commission monitoring the cease-fire. The government has reported the attack to the commission, but African Union monitors in Darfur have not yet been able to investigate the report, said Allam-mi, who is also an adviser to Chadian President Idriss Deby. Meanwhile, the Justice and Equality Movement, one of Darfur's two main rebel groups, said on its Web site Wednesday that the military has in the last four days bombed and completely destroyed eight villages in Darfur. No other details of the attacks were provided, and it was not immediately possible to independently verify the report. It was not clear if the bombing was reported to the cease-fire monitors.
