CIA chief Brennan: Secret US report on 9/11 'will absolve Saudi'

Nearly 3,000 people were killed in the 9/11 attacks

The probable publication of classified parts of a 2002 congressional report into the 9/11 attacks will clear Saudi Arabia of any responsibility, CIA chief John Brennan has said.

Keeping 28 pages of the report secret has sparked speculation that the attack had received official Saudi support.

The classified pages are also central to a dispute over whether the families of 9/11 victims should be able to sue the Saudi government. Saudi Arabia denies any involvement. Fifteen out of the 19 hijackers in 2001 were Saudi citizens.
