Package bombs, which include letters, parcels, and anything delivered by postal or courier service, are not a new technique and have been used by terrorists and anarchist groups. Many of these bombs are triggered when victims handle or open the packages, although they can be initiated in other ways.
Package bombs come in a variety of shapes and sizes, and they may look harmless. There are a number of characteristics that may lead you to become suspicious of a letter or package.
