CAIRO (AP) — A leading human rights group has called on the United States and the United Nations to impose more sanctions on the Sudanese leaders responsible for the ongoing atrocities in Darfur. Human Rights Watch said Friday that Washington should impose targeted sanctions. The United States took over the rotating presidency of the U.N. Security Council on Aug. 1. . The New York-based watchdog said at least seven villages and towns have been nearly destroyed in West Darfur province. Sudan plunged into chaos in April when monthslong tensions between the military and the paramilitary Rapid Support Forces exploded into open fighting.
