On December 16, 2025, FARC dissidents carried out a coordinated, multi-axis attack in Buenos Aires, Cauca Department, southwestern Colombia, employing a combination of IEDs, improvised indirect fire, armed UAVs, and sustained small-arms fire against police and government facilities. The operation deliberately isolated the town through the emplacement of gas-cylinder IEDs on access routes and the destruction of communications infrastructure, delaying reinforcements and prolonging the engagement.
The attack was attributed to the Jaime Martínez Front of the Central General Staff and demonstrated a high level of planning, manpower coordination, and technical capability, including the use of vehicle-mounted improvised mortar firing platforms. Subsequent security operations identified an associated workshop in the area, where large vehicle-based improvised mortar platforms, VBIEDs and improvised bomblets, among other items, were discovered, underscoring the group’s sustained indirect-fire capability in southwestern Colombia.
