"Compared to other parts of the world, the potential threat emanating from terrorism is low in most countries in Latin America. Most terrorist acts occur in the Andean region of South America, committed by two Colombian guerrilla groups--the Revolutionary Armed Forces of Colombia (FARC) and the National Liberation Army (ELN)--and one Peruvian guerrilla group, the Shining Path (SL). All three of these groups have been designated by the U.S. State Department as Foreign Terrorist Organizations (FTOs). The FARC, however, has been engaged in peace negotiations with the Colombian government since 2012, culminating in a peace accord signed in September 2016. Although the accord was narrowly rejected by a national plebiscite in early October, both sides hammered out a new peace accord in November 2016, which was ratified by Colombia's Congress at the end of that month. Negotiations between the Colombian government and the smaller ELN had several false starts in 2016, although to date formal talks with the government have not started. The Shining Path has been significantly diminished because of Peruvian military operations."
