Terrorism in Ecuador was, until the outbreak of the current security crisis due to the government's fight against drug-trafficking organizations, a relatively rare and sporadic occurrence as the country, despite periods of economic and political instability, was traditionally known as a peaceful state in Latin America. This was unlike its neighboring states, Peru and Colombia, which have suffered widespread violence by insurgent, paramilitary, and drug trafficking organizations (all using terror tactics) in different degrees for more than fifty years.Attacks in Ecuador have traditionally been carried out by small domestic organizations (both known and anonymous) as well as, in a lesser degree, foreign Colombian groups operating within Ecuador's borders. A number of terror organizations have been inactive for several years.

The package was immediately examined by US Embassy security personnel and local bomb technicians, initially appearing to contain 15 dynamite sticks with two blasting caps connected with wire to a black box detonator. However, a later examination of the device found that the dynamite sticks were actually filled with dirt to give it a weight similar to that of dynamite.
