Details Emerge On Explosives Used In Boston Marathon Bombings

By Susan Duclos

Details are being reported about the type of homemade explosive devices that were used in the Boston Marathon bombs, which killed three and wounded more than 170 people on Monday, April 15, 2013.

Via Washington Post:

Officials found that the bombs consisted of explosives put in common 1.6-gallon pressure cookers, one containing shards of metal and ball bearings, the other packed with nails, according to a person close to the investigation who spoke on condition of anonymity because the investigation was still going on. Both bombs were stuffed into duffel bags, the person said.

At a news conference, FBI agent Richard DesLauriers, FBI agent in charge in Boston, confirmed that investigators had found pieces of black nylon from a bag or backpack and fragments of BBs and nails, possibly contained in a pressure cooker. He said the items were sent to the FBI for analysis at Quantico, Va.

Pressure-cooker explosives have been used in international terrorism, and have been recommended for lone-wolf operatives by Al-Qaida’s branch in Yemen. But information on how to make the bombs is readily found online, and U.S. officials said Americans should not rush to judgment in linking the attack to overseas terrorists.
