WASHINGTON - The two bombs that went off at the Boston Marathon, killing three people and wounding 264, were detonated with the kind of remote device used to control a toy car, US investigators told a House of Representatives panel on Wednesday.
"It was a remote control for toy cars," US Representative Dutch Ruppersberger, the top Democrat on the House Intelligence Committee, told reporters after officials from the Department of Homeland Security, FBI and National Center for Counterterrorism briefed the committee.
"Which says to me, and brother number two has said, they got the information on how to build the bomb from Inspire magazine," Ruppersberger added.
Inspire was created by the American-Yemeni preacher Anwar al-Awlaki, a leader of al-Qaida's affiliate in Yemen who was killed in a US drone strike.
Ruppersberger said the article on bomb-building in Inspire was headlined: "How to build a bomb in your mom's kitchen."
Ruppersberger also confirmed that at least some of the explosives used in the attack had come from a fireworks shop in New Hampshire.
