The United States is opposing the inclusion of any Sudanese official on a potential UN Security Council sanctions list of individuals blocking peace in Darfur, two diplomats said on Wednesday. The United Nations is trying to halt atrocities in Sudan's western region of Darfur where the government is accused of backing Arab militia, known as Janjaweed who have raped, killed and driven more than 2 million African villagers from their homes. But the United States recommended for the sanctions list just one middle-ranking Janjaweed militiaman.
