Two former U.S. senators, who led inquiries into the 9/11 attacks, have said that the government of Saudi Arabia, despite being an ally of U.S in the fighting terrorism, may have played a key role in the bombing of the twin towers a decade ago.

I am convinced that there was a direct line between at least some of the terrorists who carried out the September 11 attacks and the government of Saudi Arabia, said former Senator Bob Graham, a Florida Democrat, in an affidavit filed as part of a lawsuit brought against the Saudi government by families of Sept. 11 victims and others, ABC News reported.

Bob Kerrey, a Nebraska Democrat, who served on the 9/11 Commission, supported Sen. Graham's claim in a separate affidavit: Evidence relating to the plausible involvement of possible Saudi government agents in the September 11 attacks has never been fully pursued.

Sen. Kerrey said it was incorrect for the Saudi government and institutions to claim that the 9/11 inquiry commission exonerated them.

Stated simply, the 9/11 Commission did not have the time, opportunity or resources to pursue all potentially relevant evidence on that important question, and the American public deserves a more comprehensive inquiry into the issue, the affidavit said.

The Saudis, with the support of the U.S. Department of Justice, have been trying to thwart a multibillion-dollar lawsuit since its filing in 2002, of which the affidavits are a part.

Saudi lawyers have reportedly begun their move to have the affidavits declared invalid with regard to the lawsuit claiming Saudi's involvement in the terrorist plot. The Saudi lawyers or the embassy haven't issued a response to the affidavits.

Despite the fact that 15 out of 19 terrorists who executed the 9/11 attack were Saudi citizens, the Saudi officials have always denied any involvement in the plot.

Families of the people who died in the attack praised the Senators for filing the affidavits and said that the enablers of 9/11 were still capable of supporting terrorism.

Finally someone who knows some of the truth about 9/11 is standing up and saying 'wait a minute, we didn't give those guys the all clear' as Saudi Arabia has been saying for several years, ABC News reported quoting Sharon Premoli of Vermont, who was in the World Trade Center when it was struck. Exonerated, I don't think so! Sharon said.
