A recipe for how to make pressure cooker bombs, which investigators say were used in the Boston Marathon attack
April 16, 2013
The recipe – along with a rationale for post-9/11 terror – was printed three years ago in al-Qaeda’s English-language promotional online magazine, Inspire.
In an article, it instructed readers on how, as its headline writers put it, to “Make a bomb in the kitchen of your Mom”.
It gave the types of explosive, timers and other ingredients needed – along with, it said, a pressure cooker.
