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.

The United States has updated a “do not travel” warning for large parts of southwestern Colombia after a wave of terrorist attacks have left over 20 people dead, underscoring growing international concern over the country’s deteriorating security situation and prompting regional authorities to demand stronger support from the leftist government of President Gustavo Petro.

The U.S. Department of State maintained most of Colombia at Level 3 – “Reconsider Travel” – citing crime, terrorism, civil unrest, kidnapping and natural disasters, but reinforced its Level 4 advisory for several conflict-hit regions, including the departments of Arauca, Cauca, Valle del Cauca and Norte de Santander.

Under the latest guidance, Americans are advised not to travel to Cauca, excluding the departmental capital Popayán, and Valle del Cauca, excluding Cali, due to crime and terrorism.

Norte de Santander and Arauca remain under the same highest warning level, while travel within 10 kilometers of the Colombia-Venezuela border is also strongly discouraged because of kidnapping risks, armed conflict and the possibility of detention.

“Do not travel to these areas for any reason,” the State Department said in its advisory, adding that violent crime, armed robbery and murder remain common, while terrorist groups continue to operate in remote and rural zones.

The warning was reinforced by a U.S. Embassy security alert issued in Bogotá on April 27, following 26 separate attacks across southwestern Colombia during the weekend of April 25. The attacks targeted transportation corridors, military installations and police stations, with authorities confirming at least 20 deaths and dozens of injuries.

Police and military facilities are frequent targets of armed groups, and the State Department warned that attacks in Colombia have included car bombs, grenades, truck bombs, explosive devices placed on roads and buildings, and even drones carrying explosives.

Illegal armed groups, including dissident factions of the former Revolutionary Armed Forces of Colombia (FARC), narcotrafficking organizations and other insurgent groups, have expanded their territorial presence in recent years, particularly in remote areas where coca cultivation, illegal mining and strategic trafficking corridors overlap.

The deadliest recent attack occurred near the El Túnel sector in Cajibío, Cauca, along the Pan-American Highway, where an explosive device detonated against civilian vehicles, killing 20 civilians and injuring over 50 more. Authorities attributed the bombing to FARC dissidents under command of alias “Iván Mordisco”.

The attack shocked the country and intensified criticism of President Gustavo Petro’s “Total Peace” policy, which seeks negotiated settlements with illegal armed groups but has faced mounting scrutiny as violence worsens in several regions.

In response, the Cauca governor’s office declared three days of official mourning. Authorities described the bombing as an “atrocious and unjustifiable” act and ordered flags to be flown at half-mast across public institutions and schools as a tribute to the victims.
The government also called for national unity and a stronger institutional response to confront armed violence in one of Colombia’s most volatile departments.

In neighboring Valle del Cauca, Governor Dilian Francisca Toro said she respected the U.S. warning but urged foreign governments and the media not to define the entire region by recent attacks.
“We ask that our region not be stigmatized,” Toro said, insisting that Valle del Cauca remains open to visitors and that violence does not represent the department’s cultural, economic and social identity.
At the same time, she sharply criticized the national government’s security response after attacks in Cali and Palmira, calling for “real, sustained and effective support” through more troops, stronger intelligence operations and direct action against criminal structures operating in the region.

Following an explosion near the Agustín Codazzi Engineers Battalion in Palmira, Toro announced an investment of nearly 70 billion pesos ($17 million) to strengthen police communications infrastructure, expand surveillance camera networks and improve secure transport corridors across municipalities.

In Cali, Mayor Alejandro Eder said an attempted attack against the Pichincha Battalion involved explosive gas cylinders, one of which failed to detonate while another exploded inside a minibus.

Authorities activated a citywide security operation and Eder offered a reward of up to 50 million pesos for information leading to the capture of those responsible. “We cannot allow terrorism to regain ground in our city,” Eder said.
