The CIA says it cannot turn over more details of its interrogations of terror suspects without spilling classified government secrets. A long-secret report released last week shed new light on alleged CIA abuses. The spy agency faced a Monday court deadline to turn over more papers, but the agency responded by telling the federal judge in the case that dozens of remaining documents must stay secret. The American Civil Liberties Union has sought the documents as part of a long-running lawsuit seeking information about the U.S. governments anti-terror programme. The civil rights group criticised the CIAs position, saying it contradicts President Barack Obamas policies on counter-terror measures and transparency in government.
