The CIA on three occasions shortly after the September 11 attacks used a widely condemned interrogation technique known as waterboarding, CIA Director Michael Hayden told Congress on Tuesday.
“Waterboarding has been used on only three detainees,” Hayden told the Senate Intelligence Committee. It was the first time a U.S. official publicly specified the number of people subjected to waterboarding and named them.
Critics call waterboarding a form of illegal torture. Congress is considering banning the technique.
Those subjected to waterboarding were suspected September 11 mastermind Khalid Sheikh Mohammed and senior al Qaeda leaders Abu Zubaydah and Abd al-Rahim al-Nashiri, Hayden said.
He said waterboarding has not been used in five years but was used then because of concerns of imminent catastrophic attacks on the United States and because authorities had limited knowledge of al Qaeda.
