Improvised incendiary devices (IIDs) typically are less expensive to make than improvised explosive devices but still are capable of creating mass casualties and causing widespread fear and panic. Improvised incendiary devices (IIDs) can be constructed easily from everyday materials available at hardware and grocery stores. IIDs can be used against many types of infrastructure targets; violent extremists have used them successfully in attacks in the United States and overseas.
