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.

Bogotá and the department of Cundinamarca are preparing to receive up to half a million visitors during Semana Santa 2026, as the Mayoralty unveiled an ambitious tourism campaign aimed at positioning the Colombian capital as a leading Easter destination in Latin America.

Branded “Paso a Paso, Caminando hacia la Pascua con María” (Step by Step, Walking Towards Easter with Mary), the initiative brings together the Alcaldía, departmental administration, tourism authorities and Archdiocese of Bogotá in a coordinated push to blend faith, heritage and culture into a single visitor experience.

The programme was formally launched inside the historic Catedral Primada de Bogotá with a concert of sacred music performed by the Heralds of the Gospel – Knights of the Virgin, a Catholic association known for its Latin Marian chants and global presence in more than 70 countries.

City officials say the strategy is designed not only to attract pilgrims but also to broaden Bogotá’s appeal as a cultural capital during one of the most important periods in the Christian calendar.

Ángela Garzón, Bogotá’s head of tourism, said the city expects around 500,000 visitors over the Easter season, drawn to a destination that embraces religious tolerance and offers a programme including gastronomy, concerts and free cultural events.

“Guatemala joins Bogotá and Cundinamarca in this second edition with its centuries-old tradition of floral carpets,” Garzón said, referring to one of the launch’s most striking features: a vibrant, handcrafted sawdust and flower carpet laid at the cathedral’s entrance by Guatemalan artisans.

Regional pilgrimage circuit

At the heart of the campaign are newly promoted routes designed to guide visitors through Bogotá’s historic churches and neighbourhoods.

Two principal walking circuits will anchor the experience. The first winds through La Candelaria and the colonial centre, linking some of the city’s most emblematic churches, including San Francisco, Las Nieves and San Ignacio, before culminating at the cathedral.

The second explores Chapinero, where 20th-century urban expansion meets ecclesiastical architecture, with stops at Lourdes Basilica and other parish churches that reflect Bogotá’s more modern religious identity.

The city’s tourism promotion institute, IDT, will also promote themed circuits, including a historic centre route focused on Marian devotion—particularly the Virgin of Sorrows—and pilgrimages to iconic sanctuaries such as Monserrate, which draws thousands of pilgrims each year.

Further south, visitors are encouraged to explore the Basilica of the Divine Child in Bogotá’s 20 de Julio district, reflecting the diversity of popular religious practices across the city.

The presence of Guatemalan artisans at the launch underscored the campaign’s international dimension. Their intricate carpet – crafted using Colombian flowers – symbolizes shared religious traditions and cultural exchange across Latin America.

Guatemala’s Ambassador to Colombia, Óscar Villagrán, described the installation as an expression of “community construction” and noted that the tradition was recognised by the United Nations in 2022 as part of humanity’s intangible cultural heritage.

The campaign also places strong emphasis on the figure of the Virgin Mary, particularly the Virgin of Sorrows, whose symbolism of suffering, resilience and hope resonates deeply with Catholics across the hemisphere.

Brother Gabriel Escobar of the Heralds of the Gospel framed Semana Santa as a moment of unity. “It is a time for reflection and sharing… a message of fraternity, charity and hope with faith,” he said during the launch event.

Beyond religion: gastronomy and nature trails

While religious observance remains central to the agenda, the IDT is keen to present Bogotá as a multi-layered destination, with a programme that includes Easter-themed food circuits, sacred music concerts and art exhibitions.

Outdoor activities also feature prominently, with hiking and cycling routes linking religious landmarks, alongside ecotourism excursions to the high-altitude wetlands of Chingaza and Sumapaz.

Authorities are also highlighting the city’s religious diversity, from well-known Catholic sites to other places of worship, such as the Bogotá Temple of The Church of Jesus Christ of Latter-day Saints and local mosques.

This broader framing aligns with Bogotá’s evolving image as a destination where spirituality intersects with architecture, history and intercultural dialogue.

The joint Bogotá–Cundinamarca strategy is also an economic play, aimed at boosting local businesses during a peak tourism window while reinforcing regional identity.

Constanza Solórzano, head of Cundinamarca’s tourism institute, said the initiative strengthens ties between the city and its surrounding region through shared traditions and gastronomic alternatives.

By packaging Semana Santa as both a devotional journey and a cultural experience, Bogotá has positioned itself as a well-connected regional hub, inviting visitors to experience not only a place of celebration, but also a landscape of memory, faith and encounter—where centuries-old rituals unfold against the backdrop of a modern, diverse capital.

As Garzón put it, Bogotá during Semana Santa offers “a meaningful experience for residents and visitors alike”—one that moves, step by step, between the sacred and everyday rituals.
