FBI says attacks foiled by detainee interrogations

KANDAHAR, Afghanistan (CNN) -- On a visit to the U.S. base at Kandahar, Afghanistan, on Wednesday, FBI Director Robert Mueller said information obtained through the questioning of al Qaeda members has thwarted terrorist attacks against U.S. interests.

"The information that has been obtained from interrogations of al Qaeda members who have been detained here in Afghanistan, as well as information gleaned from documents found in Afghanistan, has prevented additional attacks against the United States facilities around the world," Mueller said.

He gave no details.

Hundreds of al Qaeda and Taliban fighters have been in custody at Kandahar airport since the Taliban regime collapsed under an onslaught of U.S.-led airstrikes and opposition ground forces.

Motivation has not been a problem for Mueller's team, he said.

"Every one of the FBI agents here ... many of them wish they were not constrained to just interrogations, because they've been in the military before and they would like to participate," Mueller said. "Our role here is to support the military in gaining what intelligence we can from the individuals who have come through here," he said.
