WASHINGTON: The United States probed links between the government of Saudi Arabia and the 9/11 attacks, finding multiple suspicions but no proven ties, documents declassified Friday showed. Part of a Congressional report that had been kept under wraps for more than a decade showed US intelligence believed that Saudi officials may have had multiple contacts with some of the 9/11 hijackers. Fifteen of the 19 hijackers were Saudi citizens. The findings however show no smoking gun for Saudi involvement, but rather an inability to “identify definitively” Saudi links to attacks on US soil and global terror. “While in the United States, some of the 9/11 hijackers were in contact with, and received support or assistance from, individuals who may be connected to the Saudi government,” the declassified document said.
