Very disturbing and graphic video of Eugene Armstrong getting executed by beheading. Eugene Armstrong was an American civil engineer in Iraq.

Responsibility for beheading was claimed by Abu Musab al-Zarqawi and his militant group. The video was originally posted on an Arab Website.

Al-Zarqawi is believed to be linked to al-Qaida and he is believed to be the person reading a statement in the video prior to the execution.

While the statement is being read, Eugene Armstrong is seen rocking his body nervously back and forth and from side to side. As soon as the last sentence was finished, the militant pulled a knife, grabbed at sitting Eugene Armstrong and started cutting his throat. Terrible scream fills the room as bound hostage is being mercilessly beheaded.

The masked killer picked severed head up and placed it on top of dead, headless body.

The speaker said that the beheading of this one was just a beginning and that others will see the same fate unless all Muslim women that are held prisoners are released.
