Colombia’s National Army reported on 10 November 2026 that 2.7 tonnes of marijuana had been seized from a bongo remolcador, a river tugboat, during a military operation in Puerto Asís, Putumayo.[1][2][3][4] The interinstitutional operation took place at the Hong Kong wharf in Puerto Asís, where authorities located the vessel.[5][6][7][8][2][9][3][10] During the procedure, officers seized the boat and found about 2,700 kilograms of a substance that by its physical characteristics resembles marijuana.[5][7][8][9][11]

The seizure came from a joint operation by the Army, the Navy and the National Police.[12][6][3][11][4][10] Units taking part under the Ayacucho Plus campaign plan included the 27th Combat Engineer Battalion of the 27th Brigade, Marine Infantry River Battalion No. 30, the Anti-Narcotics Directorate, intelligence unit Sipol and criminal investigation unit Sijín.[5][7][8] The Army announced the operation in its regular bulletin La Primera del Día, describing the seizure as one of the largest drug loads intercepted so far this year in that border area.[1] According to preliminary Army information, the shipment belonged to the Comandos de Frontera structure of the Segunda Marquetalia dissidence, one of the residual organised armed groups operating in the region.[1][7][8][11][4]

The Army estimated that the seizure prevented about 27,000 doses of the substance from entering illegal markets.[5][8] Authorities did not specify the drug’s commercial value or the shipment’s destination.[12] Armed groups use the Putumayo River corridors along the Ecuador border to move drugs toward Brazil and other international destinations, so military and police units maintain permanent controls in the area.[1] The 27th Brigade, part of the Army’s Sixth Division, said joint operations would continue against illegal economies in Putumayo.[5]
