Five Blackwater contractors were killed on January 23, 2007, in Iraq when their Hughes H-6 helicopter was shot down on Baghdad's Haifa Street. The crash site was secured by a personal security detail, callsign "Jester" from 1/26 Infantry, 1st Infantry Division. Three insurgents claimed to be responsible for shooting down the helicopter, although this has not been confirmed by the United States. A U.S. defense official has confirmed that four of the five killed were shot execution style in the back of the head, but did not know whether the four had survived the crash.
