LONDON (AFP) - A British inquiry into alleged complicity in the mistreatment of terror suspects will look into new claims that the spy agency MI6 was involved in rendition to Libya , a spokesman said Monday. Prime Minister David Cameron set up the Gibson inquiry in July 2010 to probe allegations that British intelligence were complicit in the torture of extremists on foreign soil after the September 11, 2001 attacks on the United States. The inquiry had focused on Guantanamo Bay detainees but decided to examine British links to the ousted Libyan regime after the discovery at the weekend of files in Tripoli which suggested MI6 involvement in rendition to Libya .
