Salahaddin Provincial Police official Mohammed Bazi said on the same day that Bailed Air Force Base was attacked by three Katyusha rockets that night, one of which hit a building where a U.S. military contractor was located on the base, causing damage to the building and injuring an Iraqi employee.
The remaining two rockets landed in the open area of the base, causing no casualties.

It used to have American officers and soldiers responsible for training Iraqi troops.
