Clashes Between Armed Groups in Colombia Kill at Least 52 Guerrillas on Eve of Presidential Election

BLUFPetro's Total Peace framework is functionally dead in Guaviare, and forensic confirmation of underage combatant deaths is unlikely within 30 days, pushing IHL accountability onto his successor.

Rival FARC dissident factions loyal to commanders "Calarcá" and "Iván Mordisco" clashed in the Barranco Colorado sector of Guaviare department, with an army source telling AFP the fighting began Monday, May 25 12. The Calarcá faction's communiqué claimed roughly 250 Mordisco fighters attacked an encampment before dawn, killing fifty and yielding a weapons cache including 49 assault rifles and four machine guns 2. San José del Guaviare Mayor Willy Rodríguez told AFP that 48 bodies lay at the scene still awaiting evacuation, with Colombian forensic authorities unable to reach the area as of Thursday 12. Defense Minister Pedro Sánchez confirmed fighting in Barranco Colorado but withheld a casualty count, calling the communiqué a "public admission" of an atrocious crime and warning that underage combatant deaths, if confirmed, would constitute IHL violations 2.

Analysis
Forensic confirmation of underage combatant deaths is unlikely within 30 days, with moderate confidence grounded in inaccessible terrain and active armed-group presence that have already blocked Brigade 22 and Medicina Legal from the sector. That delay pushes IHL accountability proceedings into the incoming government's term. The Calarcá communiqué simultaneously marks the operational collapse of Petro's Total Peace strategy and functions as a political document framing Mordisco as criminally reckless on the eve of a security-defined election. Calarcá had clear incentive to inflate both the body count and the weapons seizure to project strength, and the absence of independent forensic access, with primary coverage resting on a single outlet, leaves that reading viable. If IHL violations are confirmed, the incoming government faces early pressure for formal accountability proceedings and U.S. security assistance conditionality tied to child-soldier prohibitions.
