This week, Al Qaeda in the Arabian Peninsula released the 12th and latest edition of Inspire, their magazine for instructing homegrown jihadis in the West:
Their "Open Source Jihad" feature provides technical how-to's and tactics for using improvised explosives and other methods to inflict damage on the West. (Remember how people laughed at their first effort, "Make a Bomb in the Kitchen of Your Mom"? We stopped laughing after we found the Tsarnaev brothers may have used it to build their pressure cooker bomb.)
This latest edition is all about making car bombs, with detailed instructions on using propane and oxygen containers and Christmas lights.
For targeting, they including the following guidance: Target bars and restaurants in Arlington and Alexandria (as well as M Street), because they are frequented by high-profile personalities:
Apparently, Adams Morgan and the U Street Corridor do not yet rate as targets. Adjust your nightlife planning accordingly.
Also of note, apparently AQAP does not recognize the legitimacy of renaming the Sears Tower to the Willis Tower, and thinks the Air Force is based in Chicago.
Inspire is available as a PDF if you search for it; if your search skills suck, I would also expect Public Intelligence to post it soon.
