A bomb-making manual, written in Arabic and published less than two months ago, made its rounds on sites used by Muslim terrorists worldwide. The manual provides specific instructions on the best methods of packaging a bomb using a pressure cooker. Previously, the English language Muslim terrorist magazine published under the name Inspire carried similar instructions, although the instructions contained within this newest manual appear to be far more advanced by comparison.
Advanced instructions pertaining to procuring the needed materials, from the pressure cookers to be used as the containers to the other components, including methods of detonation to methods of disguising the bombs themselves, appear to be consistent with the information made public by law enforcement officials investigating the bombing at the Boston Marathon on Monday.
The individual behind the independent monitoring of Arabic language websites and turning over such findings to U.S. and other intelligence agencies as such plans are found is an independent undercover operational asset known as “Archangel,” who has a widely known and well-respected track record for successful infiltration of “locked” or difficult to find websites and forums.
The intelligence agencies of the U.S. and other countries have been provided with ample material from “Archangel.” Most notable and relevant to the latest bombing is the focus on “sporting events” as potential targets, as detailed in a previous issue of Inspire magazine. Below are two images extracted and appropriately redacted from the latest version of the bomb-making manual.
