The United States government this week labelled the actions of Sudan's paramilitary forces as genocide and imposed sanctions on its leader for the "horrific, systematic atrocities" committed by his forces in a war that has gripped Sudan for nearly two years, killing tens of thousands of people and driving more than 12 million from their homes. Yet at the same time, the US administration denies that war crimes, crimes against humanity and genocide are being committed in the Gaza Strip.
