Rising Violence in Colombia: Highway Explosion Leaves 21 Dead, Dozens Injured

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.
