The New York Times has an article on the extensive ties between top members of the Saudi ruling family and terrorist groups, as new evidence is revealed by the families of 9/11 victims — evidence that is being ignored and suppressed by the US government: Documents Back Saudi Link to Extremists.

WASHINGTON — Documents gathered by lawyers for the families of Sept. 11 victims provide new evidence of extensive financial support for Al Qaeda and other extremist groups by members of the Saudi royal family, but the material may never find its way into court because of legal and diplomatic obstacles.

The case has put the Obama administration in the middle of a political and legal dispute, with the Justice Department siding with the Saudis in court last month in seeking to kill further legal action. Adding to the intrigue, classified American intelligence documents related to Saudi finances were leaked anonymously to lawyers for the families. The Justice Department had the lawyers’ copies destroyed and now wants to prevent a judge from even looking at the material.

The Saudis and their defenders in Washington have long denied links to terrorists, and they have mounted an aggressive and, so far, successful campaign to beat back the allegations in federal court based on a claim of sovereign immunity.

Allegations of Saudi links to terrorism have been the subject of years of government investigations and furious debate. Critics have said that some members of the Saudi ruling class pay off terrorist groups in part to keep them from being more active in their own country.

But the thousands of pages of previously undisclosed documents compiled by lawyers for the Sept. 11 families and their insurers represented an unusually detailed look at some of the evidence.

Internal Treasury Department documents obtained by the lawyers under the Freedom of Information Act, for instance, said that a prominent Saudi charity, the International Islamic Relief Organization, heavily supported by members of the Saudi royal family, showed “support for terrorist organizations” at least through 2006.

A self-described Qaeda operative in Bosnia said in an interview with lawyers in the lawsuit that another charity largely controlled by members of the royal family, the Saudi High Commission for Aid to Bosnia, provided money and supplies to the terrorist group in the 1990s and hired militant operatives like himself.

Another witness in Afghanistan said in a sworn statement that in 1998 he had witnessed an emissary for a leading Saudi prince, Turki al-Faisal, hand a check for one billion Saudi riyals (now worth about $267 million) to a top Taliban leader.

And a confidential German intelligence report gave a line-by-line description of tens of millions of dollars in bank transfers, with dates and dollar amounts, made in the early 1990s by Prince Salman bin Abdul Aziz and other members of the Saudi royal family to another charity that was suspected of financing militants’ activities in Pakistan and Bosnia.
