I found this memorial inside the Port Authority Administration Building at JFK Airport. You can take a closer look at the various components of the memorial here.
The map shows the locations of nine 9/11 memorials scattered around Afghanistan. As the accompanying plaque explains, each memorial consists of a piece of steel that was recovered from the wreckage of the World Trade Center, given to a team of Special Forces soldiers at the start of the US invasion in 2001, and ceremonially buried following the completion of the team's mission.
