NAIROBI, Kenya -- A U.S. based advocacy group says in a new report that Sudan's government has committed war crimes since mid-2011 in two of its southern states near the border with South Sudan.

The Enough Project said Wednesday that two years of eyewitness reports, photos, video and satellite imagery present strong evidence that Sudan should be referred to the International Criminal Court.

The group said it has documented the deliberate burning of nearly 300 square miles (756 square kilometers) of farms, orchards and grasslands for grazing cattle, and the deliberate destruction of 42 villages in the states of South Kordofan and Blue Nile.

Residents there are more aligned with South Sudan than Sudan. When those two countries separated in 2011 the residents found themselves on the Sudan side of the new border.
