US interrogators beat and abused a suspected Pakistani terrorist in his home country before he was sent to the Guantanamo Bay military prison, his father alleged in testimony released Monday. Majid Khan, who graduated from a Maryland high school, was deprived of sleep and tied in painful positions during grueling interrogation in the days following his capture, his father, Ali Khan, said in a statement. He wrote it to undercut the military's claims that his son helped al-Qaida plan attacks inside the United States. A spokesman for the Central Intelligence Agency, which held Khan in secret prisons for three years before his transfer to Guantanamo, denied allegations of torture. "The United States neither conducts nor condones torture, and the agency acts in strict accord with American law," spokesman Paul Gimigliano said.
