GENEVA (AFP) - Amnesty International Tuesday accused the forces that overthrew Muamer Gaddafi of war crimes, saying Libyas National Transitional Council must act to stop reprisal attacks and arbitrary arrests. A report by the human rights watchdog consists mainly of damning examples of violations by Gaddafis regime but also outlines serious abuses committed by the new regime forces in a brutal settling of scores. Amnesty said dozens of people suspected to be former security agents, Gaddafi loyalists or mercenaries had been killed after capture since February in eastern Libya.
