Escalating Violence in Southwest Colombia
Between 25 April and 2 May 2026, more than 30 coordinated attacks struck the departments of Cauca and Valle del Cauca, including a bomb that ripped a tunnel on the Pan-American Highway in Cajibío. Reported fatalities range from 20 to 26, with 56 people injured and dozens of vehicles destroyed. The wave also encompassed armed assaults on police stations, a military base in Cali, and a drone strike on a police facility in Santa Ana.
Background: 2016 Peace Deal and the “Total Peace” Policy
The 2016 accord with the Revolutionary Armed Forces of Colombia (FARC) ended large-scale hostilities but left dissident factions that rejected the deal. President Gustavo Petro, elected in 2022, launched a “total peace” strategy that seeks ceasefires and negotiations with all armed groups, including left-wing rebels, organized crime, and dissident FARC-EMC factions.
Key Actors
- Gustavo Petro – President, architect of “total peace.”
- Pedro Sánchez – Defense Minister, overseeing security deployments.
- Iván Mordisco (Néstor Vera) – Leader of the FARC-EMC dissident network blamed for the highway bombing.
- Iván Jacobo Idrobo Arredondo (“Marlon”) – Alleged commander of the Western Bloc, targeted with a $1.4 million reward.
- Iván Cepeda – Petro’s presidential candidate, championing continuation of negotiations.
- Paloma Valencia – Right-wing presidential candidate demanding a hard line against armed groups.
- Abelardo de la Espriella – Far-right candidate advocating a “radical order” military offensive.
- María Victoria Llorente – Executive director, Ideas for Peace Foundation, analyst of violence trends.
- Octavio Guzmán – Governor of Cauca, coordinating regional response.
Data & Statistics
- Attacks: 26 recorded incidents in two days (defense ministry).
- Casualties: 20–26 deaths, 56 injured, 5 children among the injured.
- Displacement: 60 000 people forced from homes after ELN–FARC-dissident clashes in early 2025.
- Security response: 25 000 military personnel, 3 700 additional police officers, and a 5-billion-peso reward for “Marlon.”
- Homicide rate: 26 per 100 000 inhabitants (2025), down from the 1990s peak of 80.
Impact on the Presidential Race
Security has become the dominant election issue. Polls released 28 April show left-leaning candidate Iván Cepeda leading with 44.3 % but facing rising support for Paloma Valencia (19.8 %) and Abelardo de la Espriella (21.5 %). Candidates cite the violence to argue for either intensified negotiations or a return to full-scale military offensives.
Official Statements & Responses
President Petro accused the attacks of “terrorist” intent, linked the explosives to “narco-terrorist” networks, and ordered an investigation into possible cross-border supply from Ecuador. Defense Minister Sánchez announced the deployment of troops, the reward for “Marlon,” and a guarantee of “full security conditions” for the May 31 vote. Right-wing candidate Valencia claimed dissident factions plotted her assassination; Sánchez dismissed the allegation. Governor Guzmán pledged “decisive, sustained and effective action” to restore order.
Criticism & Opposition
María Victoria Llorente stated that “total peace has failed,” noting the expansion of disputed departments from six to 13-14. Francisco Daza of the Colombian Peace and Reconciliation Foundation warned that illegal armed groups are “seeking to limit the degree to which people participate in the electoral process.” Political analyst Javier Garay labeled the peace policy “naïve,” arguing it allowed dissidents to regroup.
On-the-Ground Reports
Witnesses described a bus stopped at a roadblock before the tunnel explosion, which created a 200-cubic-meter crater. Survivors recounted gunmen in camouflage forcing Senator Aida Quilcué and her bodyguards to kneel during a February kidnapping in Cauca. Local residents reported increased road blockades and drone-delivered explosives targeting police outposts.
Conflicting Reports & Gaps
Death toll figures differ: The Guardian cites “at least 20” deaths, NPR reports 21, while AP mentions 26. The origin of the explosives remains unverified; Petro’s claim of Ecuadorian supply lacks independent confirmation. The National Liberation Army (ELN) denied any ceasefire agreement, contradicting earlier reports of a tentative truce.
