Bombs frequent in U.S.; 172 ‘IED’ incidents in last 6 months, by 1 count

The two explosions that killed three people and wounded more than 170 Monday in Boston were dramatic, the deadliest bombing in the United States since April 19, 1995, when a truck loaded with fertilizer blew up outside the federal building in Oklahoma City, killing 168. But the method of attack wasn’t particularly surprising to anti-terrorism experts: a homemade bomb that officials refer to as an IED, or improvised explosive device.
