A 15:27 minute video providing instruction for the preparation of nitroglycerin, referred to as a ?sensitive explosive substance,? was recently posted to a jihadist forum. The narration and demonstrations illustrate the necessary materials for the compound and the step-by-step preparation process including multiple measurements to ensure proper ratios.
This video seems to be of the same production and narration as others which explained the manufacture of a ?thunder bomb ? and an explosive belt for suicide operations .
The video clip, a summary of the instruction, and a translation of selected portions are provided to our Intel Service members.
