CIA Director John Brennan is apologising to Senate intelligence committee leaders after his top investigator found that CIA employees acted improperly when the CIA searched Senate computers earlier this year.

The CIA's insistence that it did not spy on its US Senate overseers collapsed Thursday with the release of a stark report by the agency's internal watchdog documenting improper computer surveillance and obstructionist behavior by CIA officers.

The head of the CIA has apologized to US lawmakers after an investigation confirmed claims that his officers had "improperly" accessed Senate computers, the agency said on Thursday.

A classified U.S. Senate report found that the CIA's legal justification for the use of harsh interrogation techniques that critics say amount to torture was based on faulty legal reasoning, McClatchy news service reported on Thursday.

In the early years after the September 11, 2001 attacks, the CIA turned some Guantanamo Bay prisoners into double agents.
