The US Department of Defence on Saturday identified the six US airmen who were killed in a plane crash over Iraq.
The airmen were on a KC-135 aerial refueling tanker last week supporting US attacks on Iran.

Major John A. Klinner, 33, of Auburn, Alabama.
Captain Ariana G. Savino, 31, of Covington, Washington.
