Al Qaeda magazine teaches how to 'make pressure cooker bombs'
Washington: A recipe for how to make pressure cooker bombs, which were used in the Boston Marathon bombings, have been a frequent weapon of militants in Afghanistan, India and Pakistan, and was once published in the Al Qaeda magazine Inspire.
Al-Qaeda's Yemen branch gave a detailed description on how to make a pressure cooker bomb in the 2010 first issue of "Inspire."
The chapter titled "Make a bomb in the kitchen of your mom," described 'pressurized cooker is the most effective method for making a simple bomb', the Washington Times reports.
The article described 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.
According to the report, 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."
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, the service said.
They found "Inspire" and "other Al-Qaeda manuals beneficial for their strategies," it added.
