Non-international armed conflict between Colombia and the Estado Mayor Central (EMC)

By juliette

Background

The pre-existing1Humanitarian Report 2024: Colombia’, International Committee of the Red Cross;  ‘Humanitarian Challenges 2025: Colombia’, International Committee of the Red Cross. NIAC between Colombia and the EMC continued during the reporting period.2Iván Mordisco, el líder de las disidencias de las FARC que vuelve al ruedo en Colombia’, Sputnik: Mundo, 23 May 2023. The EMC is the largest dissident group of the former FARC-EP and self-identifies as its successor.3 M. Pérez Gallardo, ‘El Gobierno colombiano lanza la ‘Operación Perseo’ contra disidentes de las FARC’, France 24, 13 October 2024. It was founded in mid-2017 after the group rejected the peace negotiations accepted by the parent and now defunct FARC-EP group in 2016.4 K. Johnson, ‘¿Cómo funciona internamente la disidencia del Estado Mayor Central de las FARC?’, Fundación conflict responses, 5 June 2023; C. Cohecha, ‘Colombia, EMC armed group begin peace process, suspend offensive actions’, Reuters, 9 October 2023. At that time, Néstor Gregorio Vera Fernández, also known as ‘Iván Mordisco’, opted not to take part in the negotiations, instead holding on to his command of around 400 members of the former FARC-EP and maintaining control of drug trafficking routes in several south-eastern Colombian regions.5 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025; ‘Central General Staff – Ex-FARC Mafia’, InSight Crime, 14 June 2024. In 2022, the EMC entered into peace negotiations with the government following Gustavo Petro’s inauguration as president, but the negotiation process was marked by significant challenges.6 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025; H. Shuldiner and S. Saffon, ‘From Total to Partial Peace: Colombia’s Talks With Crime Groups Fragment’, InSight Crime, 3 May 2024. In late 2023, the Colombian National Army advanced in the Cauca region, a stronghold of the EMC, which caused rifts within the criminal group.7 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025; H. Shuldiner and S. Saffon, ‘From Total to Partial Peace: Colombia’s Talks With Crime Groups Fragment’, InSight Crime, 3 May 2024; O. M. López, ‘Comandante del Ejército ratificó operaciones contra disidencias hasta llegar a El Plateado en Argelia, Cauca’, Infobae, 29 August 2023. The group then broke up. The faction under Ivan Mordisco after the split then disengaged from peace talks with the government while the other faction of the EMC (the EMBF) continued negotiations with the government.8 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025; H. Shuldiner and S. Saffon, ‘From Total to Partial Peace: Colombia’s Talks With Crime Groups Fragment’, InSight Crime, 3 May 2024. Repeated efforts by the Colombian Government to achieve a peace deal with the EMC have not been successful.9 C. Cohecha, ‘Colombia, EMC armed group begin peace process, suspend offensive actions’, Reuters, 9 October 2023; M. Pérez Gallardo, ‘El Gobierno colombiano lanza la ‘Operación Perseo’ contra disidentes de las FARC’, France 24, 13 October 2024; ‘Gobierno de Colombia suspende cese al fuego con una parte del EMC’, Voice of America, 16 July 2024; R. Cué Barberena, ‘El Gobierno colombiano finaliza tregua con el EMC, aunque la mantiene con algunas facciones’, France 24, 17 July 2024. Clashes between the two parties were particularly frequent in the departments of Cauca and Valle del Cauca.10Un disidente de las FARC muere en un enfrentamiento con el Ejército en Colombia’, Swiss Info, 24 June 2024; F. Agudelo, ‘Así fue como el frente Carlos Patiño de las disidencias de las Farc ejecutó el ataque en contra de tropas del Ejército en Balboa, Cauca’, Infobae, 15 March 2025; ‘Diez disidentes de las Farc murieron en el Cauca: cuidaban la “retaguardia” de la estructura Carlos Patiño’, Semana, 5 March 2025; V.

Intensity

The Colombian National Army and EMC continued to clash frequently throughout the reporting period.11Colombia anuncia inicio de negociaciones de paz con disidentes de FARC’, Swiss info, 13 March 2023.

Violence escalated during April 2024, just one week after the EMC once again withdrew from peace negotiations.24Colombia: abatidos 15 guerrilleros de las disidencias FARC’, DW, 25 April 2024; Ejército Nacional de Colombia, X, 25 April 2025. The Colombian National Army and Air Force launched a military operation against the EMC in El Plateado, a rural area of Argelia in the southern department of Cauca. The Colombian National Army used heavy artillery, including howitzers and long-range mortars, killing at least fifteen fighters and injuring at least twelve others.25 L. Muñoz Medina, ‘Golpe contundente contra disidencias de las Farc en Argelia, Cauca: 15 subversivos fueron neutralizados’, Infobae, 25 April 2024;  L. Reynoso, ‘“Si es guerra, es guerra”: 15 muertos del Estado Mayor Central por un ataque con artillería del Ejército’, El Pais, 26 April 2024;‘Colombia: 15 disidentes de las FARC mueren en “la mayor acción” de la ofensiva contra el EMC’, France 24, 26 April 2024; ‘Duro golpe al Estado Mayor Central en el Cauca: Ejército dio de baja a 15 disidentes en El Plateado’, El Colombiano, 25 April 2024. Another significant attack and counter operation occurred between the two parties on 12 October 2024.26Petro ordenó bombardear a disidentes de las FARC tras ataque con drones’, Cooperativa, 12 October 2024. The EMC launched a drone attack killing at least seventeen civilians.27[ATTACK] FARC Dissidents Escalate Drone Attacks in Colombia’, Modern insurgent, 20 April 2025; M. Pérez Gallardo, ‘El Gobierno colombiano lanza la ‘Operación Perseo’ contra disidentes de las FARC’, France 24, 13 October 2024. In response, President Petro ordered an aerial campaign,28 Gustavo Petro, X, 12 October 2024. as part of ‘Operation Perseus’ in an attempt to regain control over El Plateado, an EMC stronghold in the municipality of Argelia.29Petro ordenó bombardear a disidentes de las FARC tras ataque con drones’, Cooperativa, 12 October 2024. Several Colombian National Army divisions were also involved, along with the National Police and special forces units.30Fuerzas Militares lanzan Operación Perseo para recuperar El Plateado – Cauca’, Comando general: Fuerza militares de Colombia, 12 October 2024. The frequency and nature of military operations launched by the EMC clearly show that this group plans its military operations. Such planned attacks meet the requirement under Article (1)1 of Additional Protocol II that attacks are to be concerted in nature.31 A. Bellal and S. Casey-Maslen, ‘The Additional Protocols to the Geneva Conventions in Context’, Oxford University Press, 2022, para1.40.

It is difficult to determine the death toll as neither the EMC nor the media reported the losses incurred by the EMC in the majority of the clashes that took place. The media did, however, frequently report on the death of soldiers involved in these clashes. For example, the July 2023 attacks resulted in the death of at least five Colombian soldiers and between one and seven dissident fighters.32 S. Olivares Tobón, ‘Tres soldados murieron en combates contra estructuras criminales en Caquetá y Bolívar’, El Combiano, 16 July 2023; C. Salazar, ‘Denuncian combates entre disidencias Farc en Putumayo: encontraron ocho cuerpos’, Infobae, 18 July 2023; G. Bajonero Vásquez, ‘Fuerte enfrentamiento entre el Ejército y disidencias Farc en Antioquia’, El Tiempo, 18 July 2023. At least five soldiers died and six others were injured during the operations against the EMC in September 2023.33 S. Rodríguez Rey, ‘Disidencias de las Farc asesinó a un teniente y tres soldados en Nariño’, Infobae, 16 September 2023; R. Irausquin, ‘Disidentes de FARC matan a cuatro soldados colombianos en vísperas de reunión con gobierno’, Extra, 17 September 2023; ‘Un militar muerto, seis heridos y uno desaparecido deja un combate con disidentes de las FARC’, Ecuavisa, 29 September 2023. Attacks during April 2024 killed another soldier and left three injured,34 F. M. Guitérrez, ‘Murió un soldado tras enfrentamiento entre el Ejército y disidencias de las Farc en Cauca’, Radio Nacional de Colombia, 17 April 2024; J. D. Rodríguez, ‘Combates entre Ejército y disidencias Farc en Cauca: un militar asesinado y tres heridos’, W Radio, 17 April 2024. while clashes in May 2024 reportedly killed at least nine soldiers.35Control del cañón del Micay enfrenta de nuevo a Ejército con disidencia de Mordisco en Cauca’, El Espectador, 6 May 2024; ‘Dos soldados colombianos mueren en un ataque de disidentes de las FARC en el Cauca’, Swiss Info, 7 May 2024; J. C. Rodríguez Parrado, ‘Dos soldados fueron asesinados por las disidencias de las Farc en zona rural de Silvia, Cauca’, Infobae, 6 May 2024; ‘El Ejército colombiano denuncia que disidencia de FARC profanó cuerpos de soldados muertos’, Swiss Info, 6 May 2024; P. C. B., ‘Gustavo Petro, tras la muerte de cuatro soldados: “La ofensiva contra el EMC en el Cauca debe ser total”’, El Pais, 7 May 2024. Another three soldiers were killed during June 2024.36 L. Muñoz Medina, ‘Atacan con drones a militares en Argelia, Cauca: hay varios heridos’, Infobae, 12 June 2024; ‘El Ejército colombiano denuncia que disidencia de FARC profanó cuerpos de soldados muertos’, Swiss info, 6 May 2024; P. C. B., ‘Gustavo Petro, tras la muerte de cuatro soldados: “La ofensiva contra el EMC en el Cauca debe ser total”’, El Pais, 7 May 2024. Another soldier was killed in November.37 J. E. Neira, ‘Ejército dio de baja a 10 disidentes de las Farc en el Meta que pretendían enfrentarse a ‘Calarcá’’, Infobae, 9 November 2024. On 11 March 2025, the EMC used a remotely detonated bomb against a vehicle transporting soldiers in Balboa municipality, killing five soldiers and leaving another sixteen wounded.38 J. D. Rodríguez, ‘5 militares muertos y 16 más heridos, 3 de gravedad, deja atentado en Balboa (Cauca)’, Infobae, 12 March 2025; F. Agudelo, ‘Así fue como el frente Carlos Patiño de las disidencias de las Farc ejecutó el ataque en contra de tropas del Ejército en Balboa, Cauca’, Infobae, 15 March 2025; ‘Latin America & Caribbean’, International Crisis Group. During April 2025, six soldiers were killed.39Mueren seis militares colombianos en un ataque de la facción del EMC de las FARC en el sudeste de Colombia’, Infobae, 27 April 2025; ‘Seis militares mueren en una emboscada en Colombia’, DW, 28 April 2025.

Internal displacement figures from territories where the EMC fought the Colombian National Army remain high.40Colombia: Population Movement (internal displacement) – DREF Operation update (MDRCO029)’, Reliefweb, 21 July 2025; ‘Humanitarian Challenges 2025: Colombia’, International Committee of the Red Cross; ‘ACAPS Thematic Report: Colombia – Anticipated implications of US stop-work orders and subsequent cuts (16 April 2025)’, Reliefweb, 16 April 2025. The EMC, however, does not fight only against the Colombian National Army, and other organized armed groups also engage in combat in some of these territories. As such, it is impossible to attribute a percentage of internally displaced persons directly to the fighting between the EMC and the Colombian National Army.

The Colombian Air Force increasingly employed aerial strikes against the EMC during the reporting period.41Ejército Nacional refuerza operaciones en Huisitó, Cauca, con más de 400 soldados’, Defensa, 25 March 2025; L. Muñoz Medina, ‘Golpe contundente contra disidencias de las Farc en Argelia, Cauca: 15 subversivos fueron neutralizados’, Infobae, 25 April 2024; J. Ownby, ‘Drones que lanzan bombas: la nueva etapa del conflicto colombiano’, El Pais, 19 June 2024. In response, the EMC has acquired drone technology, using remotely piloted aircraft in several attacks, dropping explosive devices, including grenades, on its military targets.42 H. Shuldiner and S. Garcia, ‘High-Level Attack Punctuates Security Crisis in Southwestern Colombia’, InSight Crime, 16 June 2024;  L. Muñoz Medina, ‘Atacan con drones a militares en Argelia, Cauca: hay varios heridos’, Infobae, 12 June 2024; J. Ownby, ‘Drones que lanzan bombas: la nueva etapa del conflicto colombiano’, El Pais, 19 June 2024; J. Bernal, ‘Sigue la violencia en el Cauca: este lunes se reportan fuertes combates entre Ejército y Disidencias en Argelia’, Infobae, 17 June 2024. The EMC has also used explosives called ‘tatucos’ against the Colombian National Army.43 J. C. Rodríguez Parrado, ‘Dos soldados fueron asesinados por las disidencias de las Farc en zona rural de Silvia, Cauca’, Infobae, 6 May 2024. Tatucos are improvised explosives that need to be activated from a ramp and are often cylinder or car bombs that require remote or timed ignition.44The constant danger of explosive hazards’, International Committee of the Red Cross, 27 March 2025.

The nature of the military opposition posed by the EMC enabled by territory under its control has led the Colombian National Army to increasingly deploy soldiers in areas controlled by the EMC. For example, the deployment of special forces and at least 1,000 other soldiers in October 2024,45Fuerzas Militares lanzan Operación Perseo para recuperar El Plateado – Cauca’, Defensa, 12 October 2024; D. E. Reyes Espinosa, ‘Disidencias de ‘Iván Mordisco’ se refirieron por primera vez a la Operación Perseo en el cañón del Micay: “Es el resultado del envenenamiento de la cúpula militar”’, Infobae, 31 October 2024; V. P. Lugo, ‘La Defensoría del Pueblo confirma la liberación de los 29 integrantes de la Fuerza Pública retenidos en El Plateado’, El Pais, 9 March 2025. and the deployment of 400 more soldiers in March 2025 in the districts of Huisitó, Playa Rica, Juntas, Fondas, and Pandiguando, in the municipality of El Tambo, Cauca.46Ejército Nacional refuerza operaciones en Huisitó, Cauca, con más de 400 soldados’, Defensa, 25 March 2025.

It is clear that the notion of intensity demanded under IHL is met in the armed violence between Colombian National Army and the EMC. The frequency, high intensity, and planned nature of the attacks initiated by the EMC illustrates the ability of the EMC to launch sustained and concerted military operations from territory under its control as required by Article 1(1) of Additional Protocol II to trigger its application.47Article 1 – Material field of application’, International Committee of the Red Cross: International Humanitarian Law Databases;   M. M. Bradley, ‘Additional Protocol II: Elevating the minimum threshold of intensity?’, International Review of the Red Cross, 2020; A. Bellal and S. Casey-Maslen, ‘The Additional Protocols to the Geneva Conventions in Context’, Oxford University Press, 2022, para1.40.

Organization

The EMC has a decentralized structure to its leadership with commanders in charge of different factions that fight in certain geographic areas. Individual commanders exercise control over the Jorge Suárez Briceño Bloc, Commander Gentil Duarte bloc, the Magdalena Medio Bloc, and the Carolina Ramírez Front.48 ‘¿En que está el “EMC” actualmente?’, Fundación conflict responses, 25 April 2024; H. Shuldiner and S. Saffon, ‘From Total to Partial Peace: Colombia’s Talks With Crime Groups Fragment’, InSight Crime, 3 May 2024; J. P. Contreras Ríos, ‘Así nació el grupo que se separó de Mordisco y que ahora negocia la paz con’, El Espectador, 4 December 2024. In April 2024, the EMC fractured, with 60 per cent of the fighters remaining with the original group under the command of Iván Mordisco.The remaining 40 per cent are now led by Alexander Díaz Mendoza, alias ‘Calarcá’, and carry out activities under the name of EMBF.49 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025. After the EMC disengaged from peace talks with the government in April 2024 following their split from EMBF, it internally restructured, and several of its blocs – the Western Bloc, the Amazonas Bloc, the Isais Pardo Bloc and the Eastern Joint Command –  were brought under the command of different leaders.50 ‘¿En que está el “EMC” actualmente?’, Fundación conflict responses, 25 April 2024; ‘Mordisco está fuera de la mesa de diálogos, confirma jefe negociador del Gobierno’, El Espectador, 16 April 2024; S. Vanegas, ‘Cuánto poder tiene en Colombia el Estado Mayor Central, la disidencia de las FARC contra la que Petro declaró una “ofensiva total”’, BBC News Mundo, 23 May 2024.

As well as a decentralized command structure for various geographically dispersed battalions, the EMC has a secretariat and a central command which oversees the battalions.51 K. Johnson, ‘¿Cómo funciona internamente la disidencia del Estado Mayor Central de las FARC?’, El Espectador, 5 June 2023; ‘Disidencias de las FARC-EP: dos caminos de una guerra en construcción – Partes 1 y 2’, Fundación Conflict Responses, 1 March 2024. Other reports, however, suggest that Iván Mordisco has absolute control over the EMC and that the command is not effectively decentralized.52 H. Shuldiner and S. Saffon, ‘From Total to Partial Peace: Colombia’s Talks With Crime Groups Fragment’, InSight Crime, 3 May 2024.

The group has rules that inform its disciplinary system. The EMC imposes a strict code of conduct and exercises social control in the communities under its influence and prohibits crimes such as rape and robbery. Its command structure permits the  existence of internal disciplinary systems in each of the decentralised regional command units and this practice further facilitates a capacity to implement IHL.53 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025; A. P. R, et al, ‘El Proyecto “Estado Mayor Central”: Un intento de unificación disidente’, Ideaspaz, October 2023.  EMC fighters receive intensive military training,54 J. C. Villaquirán Úsuga, ‘Así funcionan los campos de entrenamiento de las disidencias de ‘Iván Mordisco’’, El Pais, 26 November 2024; ‘Exclusivo: así son las ‘escuelas’ de enfermería y entrenamiento de las disidencias de Iván Mordisco’, Semana, 25 November 2024; ‘Las ‘escuelas’ de la muerte del temido Iván Mordisco: SEMANA revela imágenes secretas de los campos de entrenamiento para los menores de edad’, Semana, 23 November 2024. which facilitates their training in IHL. EMC recruits learn, among other skills, how to handle explosive-laden drones.55 J. C. Villaquirán Úsuga, ‘Así funcionan los campos de entrenamiento de las disidencias de ‘Iván Mordisco’’, El Pais, 26 November 2024; ‘Exclusivo: así son las ‘escuelas’ de enfermería y entrenamiento de las disidencias de Iván Mordisco’, Semana, 25 November 2024. The EMC’s sophisticated leadership structure is akin to responsible command which in turn enables the EMC to have the ability to implement Additional Protocol II.

It is a part of the military tactics of the EMC to form alliances to execute military operations. The practice is not without a challenge in that the EMC battalions in various regions may be fighting an armed group which is part of an alliance elsewhere.56 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025. The EMC controls several militarily important corridors as well as territory in several municipalities and along the Venezuelan border, all of which enhances its logistical capacity.57 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025. It funds its military activities using some of the profits from its criminal activities which include drug trafficking, illegal gold mining, extortion, kidnappings, contraband and money laundering.58 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025; ‘Disidencias de las FARC-EP: dos caminos de una guerra en construcción – Partes 1 y 2’, Fundación conflict responses, 1 March 2024.

Often, forced recruitment is employed to ensure full strength in the ranks of the military wing. The EMC also recruits children.59 J. Sampier, M. R. Tortosa and E. Breyne, ‘Mapping and Profiling the Most Threatening Criminal Networks in Latin America and the Caribbean’, El Paccto, 2025; UNSC, ‘United Nations Verification Mission in Colombia’, UN Doc S/2025/188, 27 March 2025. Figures provided by the Colombian Ministry of Defense suggest that EMC membership is growing, its ranks growing from 3,545 in 2022 to 3,860 in the first half of 2023.60 S. Rodríguez Álvarez, ‘Cifras secretas del gobierno confirman que todos los grupos armados crecieron’, La Silla Vacía, 13 March 2024. Reports suggest that as of December 2024, the group had 6,000 fighters in its military wing.61 J. P. Contreras Ríos, ‘Así nació el grupo que se separó de Mordisco y que ahora negocia la paz con’, El Espectador, 4 December 2024.

The EMC speaks with one voice through Andrey Avendaño (an alias) who, at the time of reporting, was the group’s spokesperson and chief negotiator.62 P. Carrillo, ‘Inicia en Colombia un nuevo intento de paz con la disidencia de las FARC’, RFI, 17 October 2023; D. M. Rodríguez Sevilla, ‘Excomandantes de las Farc encabezados por ‘Timochenko’, hoy líder de Comunes, no entregaron todos los bienes que recibieron ilegalmente en la guerrilla, dijo cabecilla de las disidencias’, Infobae, 30 December 2024.

Territorial control is an organizational criterion under Article 1(1) of Additional Protocol II.63Article 1 – Material field of application’, International Committee of the Red Cross: International Humanitarian Law Databases.
