Self-proclaimed Sept. 11 mastermind Khalid Shaikh Mohammed told U.S. military officials that he had lied to the CIA after being abused, according to documents made public Monday. The claim is likely to intensify the debate over whether harsh interrogation techniques generated accurate information.

Mohammed made the assertion during hearings at Guantanamo Bay, Cuba, where he was transferred in 2006after being held at secret CIA sites since his capture in 2003.

"I make up stories," Mohammed said, describing in broken English an interrogation probably administered by the CIA concerning the whereabouts of Al Qaeda leader Osama bin Laden. "Where is he? I don't know. Then, he torture me," Mohammed said of his interrogator. "Then I said, 'Yes, he is in this area.' "
