Al Qaeda magazine on pressure cookers: ‘Make a bomb in the kitchen of your mom’
Question of the Day
CAIRO — Homemade bombs built from pressure cookers, a version of which was used in the Boston Marathon bombings, have been a frequent weapon of militants in Afghanistan, India and Pakistan. Al-Qaeda's branch in Yemen once published an online manual on how to make one, urging "lone jihadis" to act on their own to carry out attacks.
President Barack Obama underlined Tuesday that investigators do not know if the twin bombing the day before that killed three people and wounded more than 170 was carried out by an international organization, a domestic group or a "malevolent individual." There has been no claim of responsibility.
Al-Qaeda's branch in Yemen gave a detailed description on how to make a pressure cooker bomb in the 2010 first issue of "Inspire," its magazine that only appears online, in a chapter titled "Make a bomb in the kitchen of your mom."
"The pressurized cooker is the most effective method" for making a simple bomb, the article said, describing how to fill the cooker with shrapnel and gunpowder and to create a detonator using the filament of a light bulb and a clock timer.
"Inspire" magazine has a running series of such training articles called "Open Source Jihad," which the group calls a resource manual for individual extremists to carry out attacks against the enemies of jihad, including the U.S. and its allies. The magazine is targeted heavily at encouraging "lone wolf" jihadis.
An issue last year reprinted an older article by a veteran Syrian jihadi Abu Musab al-Souri addressing would-be jihadis proposing a long list of possible targets for attacks, among them "crowded sports arenas" and "annual social events."
Notably, Army Pfc. Naser Jason Abdo, who was convicted and sentenced to life in prison last year for the Fort Hood restaurant bombing plot, was discovered to have a copy of the "How to build a bomb in the kitchen of your mom" article, according to the FBI. Investigators found bombmaking materials in his hotel that included a pressure cooker and gunpowder, according to testimony at his trial.
The SITE Monitoring Service, a U.S. independent group tracking militant messaging online, noted that Islamic extremists are not the only ones paying attention to the al-Qaeda magazine: White supremacists have also circulated copies on their web forums. They found "Inspire" and "other al-Qaeda manuals beneficial for their strategies," it said.
Over the course of 10 issues the past three years, "Inspire" has given detailed instructions with diagrams and photos on how to use automatic weapons, produce remote control detonators, set fire to a building or create forest fires. In the most recent issue, put out in March, it described how to set fire to a parked vehicle and how to cause road accidents with oil slicks on a road or tire-bursting spikes.
The chapters, including the one on pressure cooker bombs, were compiled into a booklet titled "The Lone Mujahed Pocketbook," released on Islamic militant web sites in March, according to SITE.
