Colombia bombing wave threatens nickel and cocaine supply chains as FARC dissidents escalate infrastructure attacks
Coordinated explosives killed 14 civilians in southwestern Colombia, part of 26 attacks in 48 hours that expose critical vulnerabilities in EV battery and narcotics supply networks.
Dissident FARC factions killed at least 14 civilians and injured 38 in coordinated bombings across southwestern Colombia on 25 April 2026, marking a tactical escalation in a region that controls 67% of global cocaine production and critical nickel refining capacity for EV batteries.
The deadliest incident struck the Pan-American Highway in Cajibío, Cauca region, when an explosive device detonated on a civilian bus. Governor Octavio Guzmán confirmed the toll included five minors, according to Al Jazeera. The attack was one of 26 criminal incidents in 48 hours, including drone strikes on a Civil Aviation radar facility and roadside bombings targeting military convoys.
President Gustavo Petro attributed the violence to armed groups linked to cocaine trafficking, calling perpetrators “terrorists, fascists, and drug traffickers.” Intelligence officials identified Iván Mordisco’s Central General Staff (EMC) faction as the primary suspect. The EMC commands an estimated 4,000 combatants across 10 departments, per InSight Crime, and has expanded territorial control by 30% since 2022.
“Cauca cannot continue facing this barbarity alone.”
— Octavio Guzmán, Governor of Cauca
Supply chain implications beyond cocaine
The Cauca and Valle del Cauca departments sit at the intersection of three supply chain networks vulnerable to instability. Colombia produced 2,664 metric tons of cocaine in 2023, a 53% surge that consolidated its 67% share of global supply, according to OilPrice.com citing UNODC data. The region also processes battery-grade Nickel from Latin American ore, feeding a global EV market projected to demand 1.09 million tonnes annually by 2030.
While Indonesia dominates nickel mining with 61.3% of 2024 global output, Colombia’s role in battery-grade refining creates concentration risk. Nickel prices recovered to $17,200 per tonne in February 2026 after dropping to $13,900 in early 2025, reflecting supply anxieties across EV and semiconductor manufacturing. Disruptions to Colombian processing facilities or port access through Buenaventura—the Pacific coast hub for maritime trafficking—would ripple through battery Supply Chains already stretched by geopolitical fragmentation, per Carbon Credits analysis.
Territorial competition drives violence
The 25 April bombings reflect intensifying competition between FARC dissidents and the National Liberation Army (ELN) for control of cocaine production zones, illegal mining sites, and Pacific trafficking corridors. Armed group presence has expanded aggressively: the Gulf Clan now operates in 392 municipalities (up 55% since 2022), ELN in 232 (up 23%), and FARC dissidents in 299 (up 30%), according to Human Rights Watch citing Colombia’s ombudsperson office.
The shift toward coordinated infrastructure attacks—car bombs, drones, roadside explosives—marks a departure from targeted assassinations. General Hugo López, commander of Colombia’s armed forces, framed the violence as retaliation for military operations, telling El Heraldo that “these acts of Terrorism are a direct reaction to the effectiveness of our military operations.” The government deployed additional troops to Cauca and Valle del Cauca following the attacks.
This April’s violence brings the massacre count to 47 incidents in four months, according to conflict monitor Indepaz. The escalation coincides with collapsed peace negotiations and joint US-Colombia operations targeting narco-trafficking leadership announced in February 2026, creating operational pressure on armed groups now pivoting to spectacular attacks against civilian targets.
Geopolitical ripple effects
The attacks expose vulnerabilities Western supply chain strategies cannot easily resolve. EV battery production relies on nickel processing concentration that tariffs and nearshoring initiatives do not address. Colombia’s dual role as cocaine supplier and battery material processor creates interdependencies where narco-financed violence directly threatens clean energy transition infrastructure, per CSIS analysis of critical supply chain fragility.
The Pan-American Highway—targeted in multiple April attacks—serves as the primary land corridor for both cocaine shipments and legitimate mineral exports moving toward Pacific ports. Sustained infrastructure disruption would force rerouting through Venezuela or Ecuador, each presenting distinct security and logistical risks.
Iván Mordisco (Néstor Gregorio Vera) leads the largest FARC dissident faction after refusing the 2016 peace accord. His EMC controls cocaine production in Meta, Guaviare, Caquetá, and increasingly Cauca. The group finances operations through cocaine taxes, illegal mining, and extortion of legitimate businesses, including energy companies operating in southern Colombia.
What to watch
Military deployment to Cauca will test whether conventional force can suppress coordinated bombing campaigns without triggering retaliatory attacks on energy infrastructure. Colombia exported 73 million barrels of crude in 2024; disruptions to pipelines or refineries would affect regional energy markets already sensitive to Venezuelan production volatility.
Nickel price movements will signal whether metals markets are pricing Colombian instability into battery supply forecasts. A sustained move above $18,000 per tonne would indicate heightened supply anxiety beyond Indonesian production dynamics.
Watch for ELN response to EMC’s tactical escalation. If the ELN matches drone and car bomb capabilities, southwestern Colombia could see sustained infrastructure warfare that forces foreign mining and energy companies to reconsider operations—accelerating the flight of legitimate investment that has already declined 15% since 2023 amid security deterioration.
