Libya’s interim government says a son of toppled leader Col. Muammar Gaddafi has been captured in the embattled city of Sirte. Mo’tassim Gaddafi was reportedly seized while trying to flee the city with his family. National Transitional Council forces have captured most of Sirte over the past week. In other Libya news, Amnesty International claims the NTC is holding some 2,500 detainees in the capital city of Tripoli alone, many without access to lawyers or judicial proceedings. The rights group says many of the prisoners have been subjected to beatings and other abuses, with black Africans particularly targeted.
