AKIPRESS.COM - The report from the Senate Intelligence Committee will be the first public accounting of the CIA's use of torture on al Qaida detainees held in secret facilities in Europe and Asia in the years after the September 11 2001 terror attacks, according to PA.

The committee is expected to release a 480-page executive summary of the more than 6,000-page report compiled by Democrats on the panel.

White House spokesman Josh Earnest said: "There are some indications that the release of the report could lead to a greater risk that is posed to US facilities and individuals all around the world.

"The administration has taken the prudent steps to ensure that the proper security precautions are in place at US facilities around the globe."

Likewise, Army Colonel Steve Warren, a Pentagon spokesman, said that "there is certainly the possibility that the release of this report could cause unrest" and therefore combatant commands have been directed to take protective measures.

According to many US officials who have read it, the document alleges that the harsh interrogations failed to produce unique and life-saving intelligence. It also asserts that the CIA lied about the covert programme to officials at the White House, the Justice Department and congressional oversight committees.

Mr Earnest said that regardless of whether the US gleaned important intelligence through the interrogations, "the president believes that the use of those tactics was unwarranted, that they were inconsistent with our values and did not make us safer".

While the White House has said it welcomes the release of the summary, officials say they do have concerns about potential security threats that could follow.

On Friday, US secretary of state John Kerry asked Senator Dianne Feinstein, the committee chairwoman, to "consider" the timing of the release.

White House officials said Mr Obama had been aware that Mr Kerry planned to raise the issue with Ms Feinstein, but they insisted the president continued to support the report's release.
