Reducing the Threat of Improvised Explosive Devices – New Report Nov. 14

Although it has been over two decades since the truck bombings of the Alfred P. Murrah Federal Building in Oklahoma City in 1995 and the World Trade Center in New York City in 1993, terrorist attacks with smaller-scale improvised explosive devices (IEDs) in Paris, Brussels, and Manchester and in New York and New Jersey, serve as concrete reminders that IEDs remain a persistent threat to the United States and its allies.

To assist the U.S. Department of Homeland Security in its mission of safeguarding the nation, a new report by the National Academies of Sciences, Engineering, and Medicine identifies priority precursor chemicals used in the manufacture of IEDs, suggests controls that could be considered as part of a voluntary or regulatory scheme, and examines trade-offs among those strategies.


Advance copies of Reducing the Threat of Improvised Explosive Device Attacks by Restricting Access to Explosive Precursor Chemicals will be available to reporters only beginning at 2 p.m. EST on Monday, Nov. 13.  The report is embargoed and not for public release before 11 a.m. EST on Tuesday, Nov. 14.  To obtain a copy of the report, reporters should contact the Academies’ Office of News and Public Information; tel. 202-334-2138 or email
