Ecuador moved into a period of national mourning after 11 soldiers were killed in an ambush near the Colombian border on May 10, 2025, according to the evidence packet. The attack was attributed to dissident FARC guerrillas and occurred amid a wider surge in violence tied to cocaine trafficking routes.

The supplied reporting says the soldiers were killed in an ambush attack near the border, where armed groups have taken advantage of routes used to move cocaine produced in Colombia and exported through Ecuador. The attack fits a pattern of cross-border insecurity that has become harder for authorities to contain.

The casualty figure is severe: 11 soldiers killed in a single attack. That toll alone signals a deliberate and concentrated strike rather than a scattered exchange of fire. The evidence does not specify whether the soldiers were on patrol, conducting an operation or traveling in a convoy, so those details cannot be added.

What the packet does support is the link between armed dissident groups and the drug economy. The incident was described as part of a spike in violence in both Ecuador and Colombia, with trafficking routes driving conflict and giving armed actors reason to target state forces. The ambush therefore belongs to a broader struggle over territory, smuggling corridors and the authority of the state near the frontier.

The evidence does not provide the exact wording of Ecuador's mourning declaration, only that a three-day period was announced after the killings. Even so, the significance is clear: the government responded to the deaths as a national event, not merely a local security incident.

Because only one source is supplied, the report must stay within those limits. There is no verified information here about the soldiers' identities, the weapons used, any arrests or whether the attackers escaped. The essential facts are the death toll, the border location, the dissident FARC attribution and the mourning response.

The event date is May 10, 2025. In the context of Ecuador's worsening insecurity, the ambush adds another reminder that violence at the border is not isolated. It is tied to the flow of drugs, the presence of armed dissident groups and the difficulty of securing long, porous frontier zones.

A national mourning period underscores how the state framed the attack: not only as a military loss, but as a blow that demanded public recognition. The evidence does not let us go beyond that reaction, but it does show the scale and political weight of the ambush.
