The US government's cover-up of Saudi Arabia's role in the September 11, 2001 terrorist attacks are associated with the deadly terrorist attacks in Paris, former Senate Intelligence Committee Chairman told Sputnik on Wednesday.

"The association is, Saudi Arabia has legitimately received the message by our United States cover-up of their role in 9/11, that they have impunity, that they can act as they want without sanction. It has allowed them to provide financial support first for al-Qaeda, then for groups like al-Shabaab, and now for ISIS [the Islamic State]," Bob Graham told Sputnik.

The cover-up has led Saudi Arabia to promoting the most extreme form of Sunni Islam, Wahhabism, former Senate Intelligence Chairman added.

Graham led the 2002 Senate investigation into the 9/11 attacks when he served as chairman of the Senate Intelligence Committee. He is currently campaigning for a Senate bill to declassify 28 pages of the 2002 Senate report which allegedly documents Saudi involvement in providing material and financial support to the hijackers who attacked the United States.

Three gunmen attacked the office of a weekly French satirical magazine Charlie Hebdo on Wednesday morning, killing 12 people. No terrorist group has yet claimed responsibility for the Charlie Hebdo attack.
