Politicians in the US Congress, including the Republican Senator Rand Paul, have urged President Obama to allow the release 28 pages of classified documents which they believe link Saudi officials with the September 11 terror attacks in 2001.

The documents were part of the 2002 joint House and Senate report "Inquiry into Intelligence Activities Before and After the [9/11] Terror Attacks", 28 pages of which have never been released.

15 of the 19 hijackers who took over four planes, crashing two into the World Trade Centre, on into the Pentagon and one into a field when passengers fought back, came from Saudi Arabia, as did Osama bin Laden. However there have long been suspicions that the Saudi regime itself was involved - which the Saudis deny.

Rand Paul, leading the bipartisan effort to introduce a Senate bill, said in a statement: "I stand with my colleagues today to call for the release of the final 28 pages of the 9/11 congressional inquiry. I firmly believe the family members of the victims of the September 11, 2001 terrorist attacks have the right to know the details surrounding the tragedies that occurred on that sad day."

Paul did not rule out reading the report on the floor of Congress unless the report is released. “We're going to try the normal legislative procedure first ... and see how that goes," said Rand.
