The Persistent Threat of IEDs Requires the Right Screening Tools
The bombs planted by brothers Dzhokhar and Tamerlan Tsarnaev that killed three people and seriously injured hundreds of others nine years ago this month at the Boston Marathon were created using pressure cookers loaded with nails and ball bearings. These improvised explosive devices (IEDs) were concealed in backpacks and hidden near the race finish line. Pressure-cooker bombs, which are pipe bombs in a different container, are favored by terrorists from New York to Afghanistan.
