Images of suspected mass graves in Sudan's Southern Kordofan state have been released by a U.S. satellite monitoring group.
The Satellite Sentinel Project says it has identified three excavated areas consistent with mass graves in Kadugli.
The Satellite Sentinel Project is calling for a full-scale investigation into violence in the region.
Fighting between Khartoum's army and pro-southern elements broke out in the area on June 5. Activists say Sudan's military is targeting the state's ethnic Nuba people, many of whom backed the south during a 21-year civil war.
The United Nations says an estimated 73,000 people have been displaced by the fighting.
