As described by the poster on LiveLeak.com:

Iraq, issued to jihadist forums today, Saturday, March 3, 2007, the execution video of the eighteen captured employees of the Iraqi Ministry of Defense. The Islamic State had announced the capture of these individuals on Thursday, March 1, claiming it to be primarily in response to the rape accusations of a Sunni woman, Sabrin al-Janabi, towards Shi’ite security forces. In that prior message, two demands were made of the Iraqi government to secure the release of these men within a 24-hour period. The following day, the group issued a second statement, announcing that due to the refusal of the Iraqi government to negotiate for the release, instead being “arrogant”, the Shari’a Courts of the Islamic State of Iraq ordered the execution of Allah’s Orders on the captured employees.

The video opens with footage of the men blindfolded and sitting in rows, and a message is shown on-screen that is also dictated. Its words are similar to those of the two prior statements, but add that the Mujahideen rose to action after the appeal of the Emir of al-Qaeda in Iraq, Abu Hamza al-Muhajir, which he presented in an audio message addressing Sabrin. They add: “This operation is only a drop in the bucket, and what will come is more wicked and bitter, with the permission of Allah the Almighty.”

Following the message, a number of the captured men, blindfolded and bound, are shown shot repeatedly with pistols by the masked Mujahideen.

Also, the Islamic State of Iraq issued a statement today indicating that fourteen other employees of the Ministry of Interior were captured on Thursday, March 1, and “Allah’s Orders” were also executed upon them.
