More than two dozen photographs of the Pentagon taken on September 11, 2001, have reappeared on the FBI's website.
The photographs have been re-published six years after they were first released.
The posting misled some to believe the photos from 9/11 had never before been seen.
FBI spokeswoman Jillian Stickels told The Associated Press on Friday the 27 photos were first posted online in 2011, but disappeared from the site because of a technical glitch.
They were restored to public view once the FBI was alerted they were missing. Stickels did not know how long they were not visible.
Several media outlets reported Thursday and Friday that the photos were previously unseen.
The photos show plane debris, damage to the building and FBI teams on the site.
