Colombia has launched a large-scale military deployment along its border with Ecuador, sending more than 15,000 troops to the region as tensions rise over security and alleged cross-border threats.

The move comes after a public exchange between Ecuadorian President Daniel Noboa and Colombian President Gustavo Petro over reports of guerrilla activity near the border. In response, Colombia’s government ordered an expanded security presence in key areas, particularly in the departments of Nariño and Putumayo.

Officials say the deployment is aimed at countering drug trafficking networks and organized crime groups operating along the 586-kilometer border. The operation includes ground forces supported by aircraft, armored units, and maritime and river patrols to strengthen control across the region.

Authorities are focusing on maintaining checkpoints and monitoring strategic routes to prevent the movement of weapons, explosives, and contraband. The Pan-American Highway and border crossings such as Ipiales are among the priority areas under increased surveillance.

The strategy also emphasizes sustained operations led by top military and police commanders, with the stated goal of dismantling criminal structures that operate across national boundaries.

Colombian officials have framed the deployment as part of a broader effort to secure the border and protect both countries from the impact of transnational crime. At the same time, they have stressed the need for cooperation between nations to address shared security challenges in the region.

The increased military presence highlights growing concern over instability along the border, where trafficking routes and armed groups continue to pose risks to local communities and regional security.
