A five-year-old story from our archive has been the subject of some recent editorial discussion here. The story, written in the immediate aftermath of the 9/11 attacks, was about confusion at the time surrounding the names and identities of some of the hijackers. This confusion was widely reported and was also acknowledged by the FBI.

The story has been cited ever since by some as evidence that the 9/11 attacks were part of a US government conspiracy.

We later reported on the list of hijackers, thereby superseding the earlier report. In the intervening years we have also reported in detail on the investigation into the attacks, the 9/11 commission and its report.

We’ve carried the full report, executive summary and main findings and, as part of the recent fifth anniversary coverage, a detailed guide to what’s known about what happened on the day. But conspiracy theories have persisted. The confusion over names and identities we reported back in 2001 may have arisen because these were common Arabic and Islamic names.

In an effort to make this clearer, we have made one small change to the original story. Under the FBI picture of Waleed al Shehri we have added the words "A man called Waleed Al Shehri..." to make it as clear as possible that there was confusion over the identity. The rest of the story remains as it was in the archive as a record of the situation at the time.

We recently asked the FBI for a statement, and this is, as things stand, the closest thing we have to a definitive view: The FBI is confident that it has positively identified the nineteen hijackers responsible for the 9/11 terrorist attacks. Also, the 9/11 investigation was thoroughly reviewed by the National Commission on Terrorist Attacks Upon the United States and the House and Senate Joint Inquiry. Neither of these reviews ever raised the issue of doubt about the identity of the nineteen hijackers.

Saudi Arabia acknowledged for the first time that 15 of the Sept. 11 suicide hijackers were Saudi citizens...

Previously, Saudi Arabia had said the citizenship of 15 of the 19 hijackers was in doubt despite U.S. insistence they were Saudis. But Interior Minister Prince Nayef told The Associated Press that Saudi leaders were shocked to learn 15 of the hijackers were from Saudi Arabia.

"The names that we got confirmed that," Nayef said in an interview. "Their families have been notified."
