Book Cites Secret Red Cross Report of C.I.A. Torture of Qaeda Captives

By SCOTT SHANE

WASHINGTON — Red Cross investigators concluded last year in a secret report that the Central Intelligence Agency’s interrogation methods for high-level Qaeda prisoners constituted torture and could make the Bush administration officials who approved them guilty of war crimes, according to a new book on counterterrorism efforts since 2001.

The book says that the International Committee of the Red Cross declared in the report, given to the C.I.A. last year, that the methods used on Abu Zubaydah, the first major Qaeda figure the United States captured, were “categorically” torture, which is illegal under both American and international law.
