Colombia’s security forces alerted late Sunday Medellín Mayor Federico Gutiérrez and Antioquia Governor Andrés Julián Rendón to cancel a planned visit to the Hidroituango hydroelectric complex for Monday, March 2, after intelligence warnings of a possible drone attack and credible terrorist threat.

The visit, which included a press conference expected to draw around 100 journalists, was intended to showcase progress at the country’s largest hydroelectric project, now reported to be 95% complete. Instead, regional officials said army security recommendations prompted an abrupt suspension after the detection of unauthorized drone activity over the area.

“The recommendation of the National Army is that the trip be postponed given the detected presence of large, unauthorized drone overflights,” the Antioquia governor’s office said in a statement, adding that the devices were believed to be operated by the 36th Front of dissident Revolutionary Armed Forces of Colombia (FARC) guerrilla.

Officials said the threat was not speculative. Security teams warned that an attack could materialise during the public event, raising concerns not only for the two high-profile politicians but also for members of the press corps and technical staff.

Rendón told Caracol Radio that the drones had been observed manoeuvring persistently over the precise location where the press conference was scheduled to take place. The activity coincided with a recent military operation in the nearby municipality of San Andrés de Cuerquia, where troops seized a drone, explosives, detonators, radios and military-style clothing from the same dissident group.

“All of this is highly coincidental,” Rendón said, adding that authorities were analyzing whether the overflights formed part of reconnaissance ahead of a planned attack.

Gutiérrez said armed groups were seeking to destabilize the country and disrupt key infrastructure. “These terrorist groups want to shut down the country, to generate damage,” he said, pointing to ongoing threats against Empresas Públicas de Medellín (EPM), the state-owned utility responsible for the project.

The cancelled visit had both symbolic and operational significance. In addition to reviewing construction progress and the installation of four turbines, officials were expected to outline new revenue flows generated by the project for Medellín and the wider Antioquia department.

Hidroituango has long been a flagship infrastructure initiative, though it has also faced years of engineering setbacks, financial strain and political scrutiny.

The press event has been rescheduled to take place in Medellín’s La Alpujarra administrative complex under heightened security.

The incident underscores growing concern over the rapid adoption of drones by illegal armed groups. Once limited to reconnaissance, commercially available drones modified to carry explosives are now being used in targeted attacks across conflict-prone regions of the country, including the southwest departments of Nariño, Cauca and Valle del Cauca.

According to military data, more than 400 drone-related attacks have been recorded in Colombia over the past two years, reflecting a sharp escalation in both frequency and sophistication. Analysts say such devices offer armed groups a low-cost, high-impact means of striking military, civilian and infrastructure targets while reducing direct exposure.

Recent attacks in Antioquia highlight the trend. In rural Segovia, a drone-delivered explosive killed three members of a family and displaced more than 100 households amid clashes between FARC dissidents and the Gulf Clan criminal group last week. In Ituango, the nearrest municiplity to the power-generating damn, another drone attack targeted a fuel station using improvised explosives.

On Saturday, in southern Bolívar, a military helicopter was struck in a drone attack attributed to the National Liberation Army (ELN) guerrilla, leaving 14 soldiers injured. Colombian military officials say some armed groups may have received external training in the use of drones for covert operations.

Colombia’s armed forces are moving to adapt to the emerging threat, announcing last October the creation of a specialized “Drone Battalion” aimed at strengthening aerial surveillance and counter-drone capabilities. However, security experts warn that defending against small, low-flying devices — some costing as little as US$600 — remains a significant challenge, particularly in mountainous terrain like that surrounding Hidroituango.

The alleged plot has also raised concerns about a possible shift in targeting strategy by armed groups, from rural security forces to high-profile political figures and critical infrastructure ahead of the May 31 presidential elections.

While no attack ultimately took place, authorities say the decision to cancel the visit reflects the seriousness of the threat.

For now, officials are treating the incident as a direct warning of how Colombia’s long-running conflict is evolving – increasingly shaped by technology, and capable of reaching beyond traditional conflict zones into strategic economic and political targets.

Medellín, Colombia – On Thursday morning, a drone dropped a mortar shell on a home in Segovia, a town in the northeast of the Antioquia department, killing three occupants of the house and leaving one critically injured.

The police identified the victims as María Cecilia Silva Silva and her two adult children, Yalusan Cano Silva and Alsonso de Jesús Silva. Silva’s other son was also wounded in the attack.

Segovia is a key center for illegal gold mining and is being contested by multiple armed groups, including the Gaitanist Army of Colombia (EGC), also known as the Clan del Golfo, and dissident groups of the now-defunct FARC rebels.

Authorities are still working to establish if the attack was directed at the family or if it was an error by the drone operators, an increasingly common occurrence as drones become the latest technology used in Colombia’s internal armed conflict. 

According to the Secretary of Security of Antioquia, General Luis Eduardo Martínez Gúzman, the victims were “a family who have nothing to do with the conflict, who were simply attacked by a drone.” 

Martínez highlighted the danger of these devices, suggesting that the explosive device was detached from the drone, which means the mortar could “fall anywhere.”

The Director of the National Police in Colombia, General William Oswaldo Rincón Zambrano, released a statement of condemnation: “[we] categorically reject this criminal act which plunges a Colombian family into mourning and demonstrates the contempt of illegal armed groups for human life and dignity.” 

He also reported that state security forces have headed to the area where the attack took place in order to verify what happened and assist in locating and capturing those responsible. He also expressed solidarity with the victims and their families.

The Governor of Antioquia, Andrés Julián Rendón took to social media to blame the security policies of the national government for the attack: “Who in their right mind could consider that this government has achieved transformations for Colombia?”

Rendón criticized President Gustavo Petro for negotiating with the armed groups involved in the conflict in Segovia, part of the leftist leader’s “total peace” policy. 

“This is the so-called ‘total peace’: concessions for criminals and burials for civilians. Antioquia demands an unwavering military offensive, full backing for the security forces, and zero leniency towards the criminals,” said Rendón. 

Drone attacks, both against armed groups as well as against security forces and the civilian population, have become widespread in Colombia. Between April 2024 and February 2026, the government recorded 418 attacks using drones. 

Tackling the mounting security crisis is a key issue in upcoming elections, which the United Nations warns may be undermined by the armed conflict.
