Washington: The CIA`s torture of Al-Qaeda suspects was far more brutal than acknowledged and did not produce useful intelligence, a damning and long-delayed US Senate report said Tuesday.
The Central Intelligence Agency also misled the White House and Congress with inaccurate claims about the program`s usefulness in thwarting attacks, the Senate Intelligence Committee said.
As the 500-page declassified summary of the committee`s report was released, President Barack Obama admitted the CIA`s actions had been counterproductive and "contrary to our values."
Among the explosive summary`s findings: a CIA operative used "Russian Roulette" to intimidate a prisoner and another -- untrained in interrogation techniques -- threatened to use a power drill.
Detainees were also humiliated through the painful use of medically-unnecessary "rectal feeding" and "rectal rehydration." One died of hypothermia while shackled, some suffered broken limbs.
CIA director John Brennan defended his agency`s adoption of tough tactics under president George W. Bush in the aftermath of the September 11, 2001 Al-Qaeda attacks on US cities.
He insisted that, while mistakes were made, brutal techniques like waterboarding "did produce intelligence that helped thwart attack plans, capture terrorists and save lives."
US embassies were on alert as committee chair Senator Dianne Feinstein pushed ahead with publication, despite Secretary of State John Kerry warning it could provoke anger around the world.
The summary is the most extensive detailing of the CIA`s brutal interrogation of Al-Qaeda suspects yet, although Obama admitted in August that: "We tortured some folks."
Feinstein told the Senate that at least 119 detainees were held under the program and many were subjected to "coercive interrogation techniques, in some cases amounting to torture."
The detainees were rounded up by US operatives beginning in 2001 after Al-Qaeda destroyed the World Trade Center in New York and damaged the Pentagon and through to 2009.
They were interrogated either at CIA-run secret prisons in allied nations or at the US detention center at Guantanamo Bay, Cuba.
Feinstein said some around the world "will try to use it to justify evil actions or incite more violence."
"We can`t prevent that. But history will judge us by our commitment to a just society governed by law, and the willingness to face an ugly truth and say `never again`."
While heavily redacted, the report is damning.
"The interrogations of CIA detainees were brutal and far worse than the CIA represented to policymakers and others," it said.
The review of 6.3 million pages of documents concluded that use of the techniques "was not an effective means of obtaining accurate information or gaining detainee cooperation."
Seven of 39 detainees known to have been subjected to so-called enhanced interrogations "produced no intelligence while in CIA custody," while others "provided significant accurate intelligence prior to, or without having been subjected to these techniques."
And in several cases "the CIA inaccurately claimed that specific, otherwise unavailable information was acquired from a CIA detainee `as a result` of the CIA`s enhanced interrogation techniques."The report was a years-long project of the committee`s Democratic members and staff. Republicans boycotted it, and on Tuesday they blasted it as a "political" assault on the CIA.
"We found that those biases led to faulty analysis, serious inaccuracies, and misrepresentations of fact," the committee`s Republicans, led by retiring Senator Saxby Chambliss, said in their minority report.
But Republican Senator John McCain, himself a former prisoner of war who was tortured in Vietnam, praised the report`s release and said harsh interrogations did little to make Americans safer.
"I know from personal experience that the abuse of prisoners will produce more bad than good intelligence," he said.
"This question isn`t about our enemies, it`s about us. It`s about who we were, who we are, and who we aspire to be."
Since coming to office in 2009, Obama has sought to distance the United States from past deeds and outlawed harsh interrogation.
In April, Feinstein`s committee voted overwhelmingly to release the summary and 20 conclusions of the secret document.
But first the lawmakers had to negotiate with the White House on redactions, an undertaking that caused deep friction between the intelligence community and the lawmakers and Senate staffers.
"We`ve declassified as much of that report as we can," White House spokesman Josh Earnest said Monday.
Former Bush vice president Dick Cheney staunchly defended the interrogation program, telling The New York Times it was "absolutely, totally justified."
"When we had that program in place, we kept the country safe from any more mass casualty attacks, which was our objective," he said.
But Senate Majority Leader Harry Reid insisted that the report shows that "not only is torture wrong, but it doesn`t work."
Rights advocates hailed the program`s exposure, although there was criticism of the Justice Department announcement that it has no plans to prosecute any US officials implicated.
"The CIA`s wrongful acts violated basic human rights, served as a huge recruiting tool for our enemies, and alienated allies worldwide," ACLU executive director Anthony Romero said.
"Our response to the damning evidence in this report will define us as a nation."
