The Federal Bureau of Investigation has re-released a batch of archival photos showing the devastation at the Pentagon following the 9/11 terror attacks.
The FBI uploaded 27 photos to its website's "FBI Records: The Vault" section, showing the horrific aftermath at the facility, located in Arlington County, Virginia.
The Pentagon was hit when Al Qaeda terrorists flew American Airlines flight 77 into the side of the building, killing 184 people.
All 59 passengers and crew on board were also killed along with the five terrorists.
Here are scenes from that unforgettable day.
