A senior advisor to the former American president, George Bush, has defended harsh interrogation techniques such as waterboarding, saying he was proud of the intelligence the US gained by using them.
Karl Rove said the use of waterboarding had helped prevent further attacks against America and its allies after the September the 11th attacks in 2001. He said the technique - a form of simulated drowning - had been used only to break the will of three high-value terrorist suspects.
