Ramzi bin al-Shibh

Ramzi bin al-Shibh, also known as Ramzi Omar, is believed to have played a central role in the planning of the Sept. 11 attacks. Mr. bin al-Shibh, who was captured in Pakistan in 2002 by American and Pakistani operatives, has been held at the American military prison at Guantánamo Bay, Cuba.
Mr. bin al-Shibh was secretly detained in Morocco after Central Intelligence Agency operatives took him there in 2002.
While detained in a prison near Rabat, Moroccan officials videotaped several of his interrogation sessions and gave the recordings to the C.I.A. The existence of the tapes of his interrogations was revealed in 2007 in a filing to a federal judge, although Mr. bin al-Shibh's name had been redacted from the documents at that time.
According to court documents, two videotapes and one audiotape, were found separately under a desk at the C.I.A. American officials said the tapes of Mr. bin al-Shibh did not depict harsh interrogation techniques.
But the new details about Mr. bin al-Shibh's detention shed light on Morocco's role as a holding site for suspected members of Al Qaeda captured by the United States. The C.I.A. began building a prison in Morocco in 2003, but it is unclear whether any detainees were kept there.
Mr. Binalshibh was born in Yemen in May 1972, and worked as a clerk at the International Bank of Yemen from 1987 to 1995. His first application for a United States visa was rejected in 1995. He subsequently applied for asylum in Germany under the name Ramzi Omar, but was rejected in 1997. In the meantime, he met Mohamed Atta, the leader of the hijackers, in a mosque in Hamburg in 1995, and the two later became roommates, according to the 9/11 Commission Report.
Mr. Binalshibh was to have been one of the hijackers. He sent the Florida Flight Training School a $2,350 deposit, but he did not attend because he was turned down four times for a United States visa. Instead, he served as a coordinator between Khalid Sheikh Mohammed, who is accused of planning the 9/11 attacks, and the operatives based in the United States.
On Nov. 13, 2009, a federal official said that Mr. bin al-Shibh, Mr. Mohammed and two other men would be tried in New York City for the attacks.
