Petro’s “Total Peace” strategy is under pressure ahead of presidential elections as violence by armed groups escalates

An explosive attack on the Pan-American Highway near the municipality of Cajibío, in Colombia’s Cauca department, left at least 21 people dead and 56 injured, Defense Minister Pedro Sánchez Suárez confirmed.

The attack occurred Saturday, April 25, on one of the main roads in the country’s southwest, an area historically affected by the presence of illegal armed groups.

The minister attributed the attack to alias “Marlon,” described as one of the most wanted leaders in the region, “for whom we are offering a reward of up to $1.4 million USD,” he said.

According to local media reports cited by El Tiempo, “the attack was initially intended to target army troops. However, a change in military plans reportedly led to the explosive being detonated while civilians were passing through the area.”

The impact of the attack was significant. Spain’s El País reported “that the explosion created a large crater, left the road covered in debris, and forced rescue operations that lasted several hours due to difficult access conditions.”

Cauca Governor Octavio Guzmán described the incident as one of the most serious attacks in the region in decades. “What happened on April 25 constitutes the most brutal and ruthless attack against civilians in decades,” he said.

The attack comes amid a resurgence of violence in southwestern Colombia, where illegal armed groups linked to drug trafficking, illegal mining and other illicit economies operate. Authorities continue operations in the area as investigations proceed to clarify the circumstances of the attack and determine responsibility.

According to reports by BBC Mundo, alias “Marlon” is a dissident FARC leader identified as Iván Jacobo Idrobo Arredondo, “the alleged head of the Jaime Martínez structure, part of the Estado Mayor Central (EMC),” one of the country’s most powerful illegal armed groups.

Operations and arrests

As part of response operations, the National Police reported the capture of José Alex Bitoco, alias “David” or “Mi Pez,” identified as the leader of the Dagoberto Ramos structure, another illegal armed faction, who is believed to have acted under orders from alias “Marlon”.

National Police Director Gen. William Rincón Zambrano said the detainee “will have to answer for the wave of terrorist activity” and linked him directly to the attack, stating that “he is responsible for what happened on April 25 in the El Túnel sector on the Pan-American Highway.”

The Defense Ministry reiterated that alias “Marlon” remains a priority target. “He is a high-value target, and we are searching for him with all the capabilities of the state. We have deployed a dedicated intelligence task force to locate him,” Sánchez said, confirming a reward of up to $1.4 million USD for information leading to his capture.

Context: criticism of “Paz Total” policy (Total Peace)

The attack comes amid growing security deterioration in Colombia, intensifying criticism of President Gustavo Petro’s “Total Peace” policy. The Ideas for Peace Foundation (FIP) has warned of a possible failure of the strategy, noting that “less than four months before the end of the government, the lack of progress in peace negotiations and the deterioration of security have become one of the main points of criticism of the Petro administration.”

According to the think tank, during the current administration “the number of disputed territories between illegal actors has nearly doubled, and the number of members in these structures has increased by 85%: they now total more than 27,000 members, including armed individuals and support networks.”

This figure not only represents a significant increase but also places the country at levels similar to, and even higher than, those seen before the peace process with the FARC began. Between 2011 and 2012, the estimate stood at around 26,800 members, compared with 14,600 at the end of Iván Duque’s administration in 2022.

The recent increase has also been rapid. According to the FIP, armed groups grew by 23.5% over the past year (from December 2024 to December 2025), reflecting a swift reconfiguration of these structures. At the same time, violence has intensified. Analysts such as Professor Karol Solís Menco note that over the weekend of April 25–26 alone, “26 terrorist attacks of varying magnitude” were recorded across the country.

Political analysis outlets point to a structural dynamic. According to La Silla Vacía, “Cauca is not experiencing an isolated event, but rather a phase of intensifying territorialized violence, marked by fragmentation among armed actors and a type of violence capable of producing national-level impacts.”

In this context, FARC dissident groups have once again taken center stage in the conflict. “Once again, attention is turning to FARC dissidents. Every attack, every gas cylinder bomb, every assault in Valle and Cauca ends with the same name on the table: the Jaime Martínez structure, one of the strongest groups of Iván Mordisco’s Estado Mayor Central,” El País reported.

Violence indicators also reflect sustained deterioration. “In the first four months of 2026, Colombia has already recorded 48 massacres, with 229 victims, most of them civilians, according to Indepaz. It is the highest figure in the past decade. With these numbers, which represent only a partial picture of the country’s violence, this election year is shaping up to be the most violent since the 2016 peace agreement with the now-defunct FARC guerrilla group,” the same outlet reported.

Cauca, where the attack took place, is considered one of the most sensitive regions. “Cauca is particularly complex because it combines multiple layers of conflict: the historic presence of Indigenous, peasant and Afro-descendant communities; illicit economies; Pacific corridors; disputes over drug trafficking routes; control of the Pan-American Highway; and the presence of FARC dissidents, particularly structures linked to Iván Mordisco,” El País said.

Experts agree that part of the difficulty lies in the design and implementation of the government’s strategy. “Early implementation was a valuable innovation in intent, but it failed to ensure minimum conditions of verification and institutional coherence,” said analyst Germán Valencia of the Peace and Reconciliation Foundation (Pares).

Taken together, these factors have led various sectors to conclude that the “Total Peace” policy faces serious structural limitations amid a scenario of armed fragmentation and territorial expansion by illegal groups.

Colombia’s presidential race has entered poll season with a revealing snapshot from Noticias RCN and Spanish firm GAD3 that points to an election defined less by early frontrunners than by who can consolidate votes after March’s inter-party consultations.

At first glance, Historic Pact senator Iván Cepeda appears comfortably ahead. The RCN poll places him at 30% voting intention — well above far-right independent Abelardo de la Espriella (22%) and miles ahead of the scattered field trailing behind in single digits.

But a deeper reading of the numbers suggests Cepeda’s lead may already be capped.

The 30% figure aligns almost perfectly with President Gustavo Petro’s loyal electoral base, which has consistently hovered between 28% and 32% since his rise to national prominence. In other words, Cepeda appears to have consolidated petrismo rather than expanded beyond it. The poll reinforces this ceiling: 5% of respondents favor a blank vote, 11% say they would vote for none of the candidates, and 14% remain undecided — a combined 30% still outside the Petro orbit and unlikely to gravitate toward Cepeda.

Further down the list, potential left-leaning or independent figures barely register: Sergio Fajardo, Aníbal Gaviria, Juan Daniel Oviedo, Roy Barreras and Camilo Romero each sit around 1%. Even Claudia López and Germán Vargas Lleras score negligible fractions. The fragmentation benefits Cepeda for now, but it also masks the absence of new voters entering his camp.

By contrast, the Right’s apparent weakness hides a powerful consolidation opportunity.

The Gran Consulta por Colombia, on March 8, shows Paloma Valencia leading the consultation vote with 23%. Yet the poll also reveals that the rest of the consultation slate collectively commands nearly 20%: Juan Manuel Galán (8%), Vicky Dávila (8%), Juan Carlos Pinzón (6%), Juan Daniel Oviedo (4%), Aníbal Gaviria (3%), Enrique Peñalosa (2%), David Luna (1%) and Mauricio Cárdenas (1%).

This bloc is electorally decisive because it represents Colombia’s ideological center — liberal technocrats, urban moderates and business-friendly reformists who reject Petro’s economic direction but resist extreme rhetoric. Valencia’s political résumé, Senate visibility and party machinery position her as the most viable leader to absorb that vote once the consultation narrows the field.

If she consolidates those nearly 20 points, her support would leap toward — or beyond — 40%, instantly surpassing Cepeda’s apparent plateau.

De la Espriella’s 22% underscores the volatility on the Right but also its fragility. His voters overlap heavily with Valencia’s base and are expected to migrate toward a unified conservative candidacy. Even Uribe has hinted that such unity is inevitable in a runoff; the RCN poll suggests it could happen much earlier under electoral pressure.

Yet the poll’s most intriguing subplot lies within the Left’s own consultation, where Roy Barreras emerges as a latent threat to Cepeda despite low headline numbers.

In the Frente Amplio consultation, Cepeda commands 34%, but the striking figure is the 44% who say they would vote for none. Barreras registers 4%, and Camilo Romero 3%, revealing a progressive electorate deeply unconvinced by the current slate.

Barreras’ political positioning explains why that matters. Though aligned with Petro’s government, his ideological lineage is closer to former President Juan Manuel Santos — pragmatic, transactional and coalition-oriented. Unlike Cepeda, Barreras is seen as someone capable of negotiating with centrists and conservatives alike. He represents continuity without ideological rigidity.

If Barreras manages to capture even part of that dissatisfied 44%, Cepeda’s narrow base could erode quickly. The RCN poll already shows Cepeda strong only where the Left is unified and stagnant where broader voters are involved.

Second-round simulations deepen the warning. Cepeda defeats De la Espriella 40% to 32%, but those numbers again reflect Petro’s core plus soft undecideds. Against Paloma Valencia he drops to 43% versus her 20% — a gap that would narrow dramatically once Valencia inherits the consultation bloc. More telling still, Cepeda’s numbers barely move across matchups, reinforcing the perception of a fixed ceiling.

Colombia’s presidential arithmetic is therefore shifting beneath the surface.

Cepeda leads because the field is divided. Valencia stands to surge because her side is about to unify. Barreras lurks as the only left-leaning figure capable of fracturing Cepeda’s ideological monopoly and attracting voters beyond Petro’s loyalists.

While headlines focus on Cepeda versus De la Espriella, the RCN poll suggests the real race may ultimately emerge after March 8 — between Paloma Valencia consolidating a broad anti-Petro coalition and Roy Barreras positioning himself as the Left’s only candidate with cross-spectrum appeal.

In Colombia’s elections, momentum follows math. And the math is just beginning to move.
