US investigators have revealed the two bombs that went off at the Boston Marathon were detonated with the kind of remote control device used for a toy car.
US Representative Dutch Ruppersberger, the top Democrat on the House Intelligence Committee said: "It was a remote control for toy cars. Which says to me, and brother number two has said, they got the information on how to build the bomb from Inspire magazine."
Inspire was created by the American-Yemeni preacher Anwar al-Awlaki, a leader of al Qaeda's affiliate in Yemen who was killed in a U.S. drone strike. Ruppersberger said the article on bomb-building in Inspire was headlined: "How to build a bomb in your mom's kitchen."
