Peacekeepers in Sudan say the army is stopping them from investigating an alleged attack on civilians in Darfur.

At least 10 people were reportedly killed when when a local militia opened fire Friday in the village of Sigili. U.N. and African Union peacekeepers say residents brought 10 bodies to their headquarters Saturday. But they say Sudanese forces are keeping them from going to the site of the alleged attack.

The United Nations says nearly a decade of fighting in Sudan's Darfur region between government-backed Arab militias and rebels has killed more than 300,000 people. Close to 2 million civilians have been forced from their homes, creating a humanitarian disaster. The Sudanese government says about 10,000 people have died.

The fighting has eased in recent years, but attacks on peacekeepers and civilians still flare up.
