The Colombian military has conducted several offensives targeting organized crime groups, specifically the Clan del Golfo and the Oficina de Envigado, in the Antioquia and Chocó regions. In late October, Operation Oppenheimer involved a bombing in Nóvita, Chocó, which killed seven members of the Clan del Golfo, including a high-ranking leader identified as Jason Arley García, alias Álex or Canoso. In Nechí, Antioquia, clashes between security forces and a different Clan del Golfo sub-structure resulted in one death, one capture, and the seizure of an arsenal including a machine gun and over 1,700 rounds of ammunition. Additionally, a suspected member of the Oficina de Envigado was captured in Guarne, Antioquia. By early November, the Colombian National Army expanded its efforts by destroying a coca paste processing laboratory in Puerto Valdivia, Antioquia. The facility allegedly belonged to the Julio César Vargas sub-structure of the Clan del Golfo. The operation resulted in the seizure of various chemical inputs and coca leaves, causing an estimated economic loss of 70 million pesos to the criminal organization. ## Timeline ### 2026-11-02: Colombian Army destroys drug laboratory in Antioquia The Colombian Army destroyed a coca paste processing laboratory in Antioquia, allegedly linked to the Clan del Golfo, causing an estimated 70 million peso loss. 3 sources. https://clstr.news/cluster/colombian-army-destroys-drug-laboratory-in-antioquia ### 2026-10-31: Colombian military operations target Clan del Golfo and Oficina de Envigado Colombian security forces conducted major operations against the Clan del Golfo and Oficina de Envigado, resulting in multiple deaths, high-level captures, and the seizure of significant weapon stockpiles. 6 sources. https://clstr.news/cluster/colombian-military-operations-target-criminal-groups-in-antioquia --- Cite as: Colombian military operations against organized crime.
