Yes, I understand that KSA is in general a backer of Islamic terrorism, including AQ, but to my knowledge there is no specific evidence directly linking them to the 9-11 attackers.

A still-classified section of the investigation by congressional intelligence committees into the Sept. 11, 2001, attacks has taken on an almost mythic quality over the past 13 years -- 28 pages that examine crucial support given the hijackers and that by all accounts implicate prominent Saudis in financing terrorism.

Now new claims by Zacarias Moussaoui, a convicted former member of Al Qaeda, that he had high-level contact with officials of the Saudi government in the prelude to Sept. 11 have brought renewed attention to the inquiry's withheld findings, which lawmakers and relatives of those killed in the attacks have tried unsuccessfully to declassify.
