Military officials say prisoners at the detention center here have provided a stream of intelligence to interrogators during the past two years, including detailed information about Al Qaeda's recruitment of Muslim men in Europe.
Military and intelligence officials also said those detainees who were cooperative had provided information about Al Qaeda's chemical and biological weapons efforts, had spoken about the training of suicide bombers, and had described Al Qaeda's use of charities to raise money for its aims.
"We have been able as a result of information gained here to take operational actions, even military campaigns," said Steve Rodriguez, a veteran intelligence officer who oversees the interrogation teams. "There are instances of learning about active cells, and we have taken action to see that the cell was broken," he said, in one of a series of interviews given to a reporter on an arranged tour.
Another American official said analysts had been able to understand a kind of network in Europe that selected young Muslims, who were later drawn into Al Qaeda by imams and Islamic cultural centers and eventually sent to Afghanistan. He said this information has been sent on in recent months to European counterparts.
