airport-securityAl-Qaida in the Arabian Peninsula is warning Americans that they’ve been working long and hard on a new tool to attack the U.S. In the latest issue of the terror group’s Inspire electronic magazine, an individual called the AQ Chef was quoted as saying they developed a bomb in 2009, but “the brothers in the external operation committee did not give us the green light until recently.” Hinting at al-Qaida in the Arabian Peninsula’s dedication to building undetectable bombs, he said in the winter 2014 edition of Inspire, released in late December, “they have developed other bombs that are more effective.” AQ Chef indicates that lessons learned from failures in past assassination attempts and plots to attack U.S. airplanes and buildings have fed the development of a new generation of what it calls “undetectable” bombs. In “The Hidden Bomb,” a 20-page section of the magazine, the writer goes into painstaking detail about how to build and test such a bomb: “For several months, we conducted a number of experiments.
