ELN drones hit Colombia’s Santa Rosa del Sur military canton, killing at least three

Situation Overview

On 7 November 2026, a drone attack hit the Cantón Militar de Santa Rosa del Sur in northern Colombia, with explosives falling on the troop dining area around 12:30 local time, followed by another wave of drones. The attack killed at least three military personnel and left 16 soldiers with severe injuries, with another 31 people affected. The attack was attributed to the ELN, and it is described as one of the deadliest incidents of 2026. The article links the escalation to a sharp rise in drone-delivered explosives since August, when Abelardo de la Espriella took office, saying at least 12 uniformed personnel have died since then compared with eight in the previous seven months. The article reports that the pace has more than tripled, from just over one death per month to nearly four, underscoring a growing reliance on aerial attacks in Colombia’s ongoing conflict.
