The FBI released an archive of photos showing the devastation at the Pentagon in the wake of the 9/11 terror attacks.

A total of 27 photos were uploaded to the FBI website "FBI Records: The Vault" under the page name "9/11 Attacks and Investigation Images."

The photos show fragments of American Airlines flight 77, which left Dulles Airport outside Washington, D.C., around 8:51 a.m. ET that morning. While on its way to Los Angeles, the plane was hijacked by Al Qaeda terrorists and crashed into the Pentagon at 9:37 a.m. ET.

Efforts by firefighters to combat the ensuing blaze and emergency responders rushing to the scene are included in the collection.

Overhead photos show the massive hole left in the side of the Pentagon when the outer rings of the building were penetrated by the aircraft.
