The Ejército Nacional de Liberación (National Liberation Army – ELN) is the largest remaining guerrilla group in Colombia, following the signing of the 2016 Peace Accord between the Colombian government and the Fuerzas Armadas de Colombia (FARC-EP).
It is estimated that the ELN currently has some 5,800 members, with 3,000 combatants and is comprised of 8 main bloques and 33 subestrucutras. The EMC mainly operates in Arauca and Norte de Santander, in the north-east of the country, but activity is seen right across to Chocó and Cauca in the west/south-west.[1]
The government is also engaged in Peace Talks with the EMC and the Segunda Marquetalia.
