Two videos and an audiotape of a terrorism interrogation that were found by the CIA in 2007 show September 11 suspect Ramzi Bin al-Shibh, a knowledgeable U.S. source told CNN on Tuesday.
On the tapes, Bin al-Shibh is seen sitting at a desk answering questions, according to the source, who said the tapes do not show any use of "enhanced interrogation" techniques such as waterboarding.
CNN reported several years ago that the tapes were found under a desk at the CIA.
An October 2007 letter from federal prosecutors to U.S. District Judge Leonie Brinkema confirmed the existence of the tapes. However, the letter did not reveal the identity of the person being interrogated.
The Associated Press first reported that Bin al-Shibh was the subject in the tape recorded in Morocco.
Bin al-Shibh's lawyer, Thomas Durkin, said Tuesday that he was unaware until now that the tapes involved his client.
Durkin declined to comment on whether the tapes would have any impact on the status of al-Shibh's case. Bin al-Shibh is one of five September 11 suspects, including Khalid Sheikh Mohammed, who originally were scheduled to be tried in New York.
"Right now, we're waiting along with everyone else as to where the Justice Department and the administration decide the cases are going to be held," Durkin said, noting that the plan to try the 11 suspects in New York appeared to have changed.
CNN Terrorism Analyst Peter Bergen said Bin al-Shibh helped plan the September 11 attacks that destroyed the World Trade Center, damaged the Pentagon and killed almost 3,000 people.
"He applied for an American visa," Bergen said Monday. "He wanted to be one of the hijackers. He was turned down. He's a Yemeni. He then basically assumed a quite important role in coordinating all the acts of the hijackers.
He was a liaison between the hijackers in the United States and Osama bin Laden in Afghanistan."
The tapes are believed to be the only ones left that show a "black site" interrogation in a third country. Other tapes showing enhanced interrogations of suspects Abu Zubaydah and Abd al-Rahim al-Nashiri were destroyed by the CIA.
