Al Qaeda in the Arabian Peninsula is threatening to execute any U.S. nationals that the terrorist group kidnaps if the U.S. government follows through with its scheduled execution of Nidal Hasan, the 2009 Fort Hood shooter.

Al Qaeda said in a statement released Monday that “the day America makes this decision,” referring to the execution of Hasan, “it will have made a decision to execute whoever among you falls captive to us.” The terrorist group voiced support for Hasan, who killed over a dozen people, and for the Omani suicide attacker who unsuccessfully planned to fly a plane into Israel’s Ben Gurion Airport this month.
