Kenya (AP) - International rights groups are accusing Sudan's government of killing 26 people in indiscriminate aerial bombardments of opposition-controlled areas in the country's main oil-producing state. Human Rights Watch and Amnesty International said in a statement Tuesday that 45 people have been wounded by the airstrikes since June in the Nuba Mountain areas of South Kordofan state. South Kordofan lies just across the border from the newly independent nation of South Sudan. It has been the site of clashes between government troops from Sudan's Arab north and black tribesmen aligned with the south. A U.S. monitoring group said last week that satellite imagery found two more mass graves in South Kordofan, bringing the total number of graves seen to eight. My take: Inasikitisha wakati wananchi wa Sudani wasio na silaha wanauawa na serikali yao AU iko kimya, NATO wakiingilia kati kuwaokoa AU itatuambia nini safari hii.
