With just over a month to go before Colombia’s May 31 presidential election, a new Invamer poll suggests the race has narrowed to three viable contenders, as left-wing senator Iván Cepeda strengthens his lead and two right-wing rivals battle for a place in the runoff.

The survey, conducted for Noticias Caracol and Blu Radio, shows Cepeda commanding 44.3% of voting intention, a significant jump from 37.1% in February. The Pacto Histórico candidate has not only consolidated support among core voters but expanded his appeal across all regions, with particularly strong gains among younger voters aged 20 to 30.

Trailing behind, but still within striking distance of a second-round berth, are Abelardo de la Espriella with 21.5% and Paloma Valencia with 19.8%. While De la Espriella has posted modest gains since February, Valencia has emerged as the fastest-rising candidate, nearly doubling her support from 10% in the previous poll.

The data underscores a central dynamic shaping the race: a fragmented right competing for a single runoff slot, even as the left coalesces behind a dominant frontrunner. According to the data, as long as the right remains divided, any division among the pro-Uribe camps will continue to benefit Cepeda. Unless there is a clear consolidation after May 31, the numbers suggest the second round will be a contest over who faces the hard-leftist and not whether he gets to the final run-off.

The collapse of Colombia’s political center has been equally striking. Former Bogotá mayor Claudia López has seen her support plunge from 11.7% to 3.6%, while former Medellín mayor Sergio Fajardo has dropped from 6.6% to just 2.5%. Both candidates have lost more than half of their previous backing and now poll well below the 4% threshold required for state reimbursement of campaign expenses.

López’s decline appears particularly acute in urban constituencies, where she previously drew strong support, including among progressive and LGBTQ voters, pointing to a broader erosion of her core base. Fajardo, meanwhile, continues to struggle to regain traction, reflecting persistent voter dissatisfaction with centrist alternatives.

Analysts are also seeing how centrist voters are shifting toward Valencia, whose ticket includes former DANE statistics chief Juan Daniel Oviedo as the vice-presidential option. Oviedo appears to be decisive in broadening Valencia’s appeal beyond the Centro Democrático base.

Despite Cepeda’s commanding first-round lead, runoff scenarios suggest a more competitive contest – particularly if Valencia secures the second spot. In a hypothetical second round between Cepeda and De la Espriella, the left-wing candidate would win with 54.6% against 42.6%. However, against Valencia, the margin narrows significantly to 51.2% versus 46.6%.

That tightening gap reflects Valencia’s growing ability to attract support beyond her base, including voters from the political center and segments of the undecided electorate. According to the poll, she outperforms De la Espriella in capturing second-choice preferences, positioning her as the more competitive challenger in a potential runoff.

When respondents were asked who they would support if their first-choice candidate failed to advance, Cepeda led with 26.7%, followed closely by Valencia at 25.7%, with De la Espriella trailing at 19.8%. López and Fajardo lagged further behind, reinforcing their diminished relevance in the race.

Cepeda’s dominance, however, is not without warning signs. While he continues to lead comfortably, his projected runoff margins have narrowed compared to earlier surveys, particularly against Valencia. The erosion suggests that while his base remains solid, opposition voters may be coalescing more effectively than before.

For now, the trajectory is clear. Cepeda has gained ground nationally despite a worsening security situation and poll conducted before the terrorist bomb on Saturday, April 25 by FARC dissidents along the Pan-American highway in which 20 persons were killed.

With less than a month until Colombians head to the polls, the race appears increasingly defined not by a crowded field, but by a three-way struggle – one frontrunner and two challengers vying for the chance to stop him.

Colombians are expressing outrage and grief after a bombing attributed to dissident factions of the former FARC killed 20 people and left injured 46, marking the country’s deadliest attack in over a decade.

The blast on Saturday afternoon tore through a stretch of the Pan-American Highway near Cajibío, in the southwestern department of Cauca, leaving mangled vehicles, a massive crater, and scenes of devastation that authorities described as among the most brutal assaults on civilians in recent memory.

Departmental governor Octavio Guzmán said the explosion, which injured at least 36 people, including children, was the “most ruthless attack against the civilian population in decades,” adding that several vehicles were overturned by the force of the blast.

Military officials said attackers blocked traffic with a bus and another vehicle before detonating explosives as cars and buses were stranded along the highway, a vital artery linking Colombia’s southwest with the cities of Popayán and Cali.

The attack, attributed to a FARC dissident faction led by Iván Mordisco, came amid a surge of violence across southwestern Colombia, with authorities reporting at least 26 attacks over a two-day period in Cauca and neighbouring Valle del Cauca. Incidents included explosions, arson attacks on vehicles, and assaults on security forces in cities such as Cali, Palmira, and Jamundí.

But as the country mourns, President Gustavo Petro faced mounting criticism after posting images of himself celebrating his birthday, prompting accusations of insensitivity and a lack of leadership during a national crisis.

Late on Saturday evening, Petro shared a photograph on social media showing himself alongside three friends, all wearing Hawaiian-style flower garland necklaces, accompanied by a message marking his birthday on April 19. “Surrounded by love and bonds of affection,” Petro wrote. “We are an army of Quixotes doing the impossible and achieving the impossible.”

The post, which appeared hours after reports of the deadly attack emerged, sparked immediate backlash from political leaders and the public, many of whom questioned the president’s priorities at a moment of national mourning.

Senator Juan Manuel Galán criticized the timing of the message, writing on social media: “19 people murdered in Cajibío, Cauca, the country bleeding, the Pan-American highway turned into tragedy… but the priorities of Gustavo Petro were clear: the country in mourning and he showing us how he celebrated his birthday.”

Presidential hopeful Paloma Valencia travelled to Palmira to meet with victims’ families and express solidarity. “We are with the people who are afraid, who are mourning their loved ones, who need to feel safe again. Petro should be here,” she said.

The criticism underscores deep tensions surrounding Petro’s security strategy, particularly his “Total Peace” policy aimed at negotiating with illegal armed groups. Critics argue the approach has failed to contain violence in regions such as Cauca, where armed groups linked to narcotics trafficking and illegal mining continue to operate with increasing intensity.

Saturday’s bombing, one of the most lethal attacks since the 2016 peace accord with the FARC, has renewed fears about Colombia’s security trajectory and the resilience of dissident factions that refused to demobilise.

Images from the scene showed debris scattered across the highway, shattered vehicles, and a large crater where the explosion occurred. Authorities confirmed that 15 women and five men were among the dead, while several of the injured remained in critical condition.

For residents of the region, the attack has deepened a sense of vulnerability and abandonment.

“Cauca cannot continue to face this barbarity alone,” Governor Guzmán said, calling for greater national support and a stronger security response.

As Colombia approaches a general election on May 31, the attack also reveals the extent to which  the state remains unable to protect civilians, let alone presidential candidates opposed to the failed security policies of the country’s first leftist administration. “Petro: You are simply a disgrace. Show some empathy. Show some respect,” noted Paloma Valencia from Palmira.

 

A bomb attack attributed to fighters from the EMC armed group killed 20 travelers trapped on the busy highway connecting Colombia’s southwestern cities on Saturday.

The tragic events in the El Tunel sector, close to the town of Cajibío, unfolded after the dissidents mounted a checkpoint on the main Via Panamericana south of Cali and 30 kilometers (20 miles) before Popayán.

The busy road runs through a mountainous region dominated by gangs run by the former guerrillas dedicated to a booming cocaine industry in hidden canyons beyond state control. At the illegal checkpoint the fighters forced truck drivers to block the road and abandon their vehicles, causing a long queue of traffic.

According to video posted online, soon after a midday the huge explosion rocked the valley mangling around 15 vehicles caught blockade including two minibuses with civilian passengers.

The governor of Cauca, Octavio Guzmán, confirmed the 20 dead civilians caught in the blast were 15 women and five men, all adults. A further 47 people were injured, of whom three were critical. Five children were recovering in hospital. Eleven of the affected persons came from the same village of Pedregosa, close to Cajibío, he added.

“What happened on April 25th constitutes the most brutal and ruthless attack against the civilian population in decades in the department of Cauca,” the governor later announced.

The bomb had displaced 200 cubic meters of soil, he said, creating a crater five meters deep in the Panamericana highway, the main route linking Cali to Popayan and on to Ecuador. Despite the damage, road crews were able to partially reopen the road six hours after the blast.

Saturday’s attack, one of the worst atrocities in recent years, comes against a background of rising conflict between state forces and dissident armed groups in the southwest of Colombia.

Terrorist tactics

Just in the last four days communities across three departments – Valle, Cauca and Nariño – reported a series of what appear to be coordinated attacks against civilian and military targets. These included:

• 24 April – A bus bomb exploded close to base of the Pichincha Battalion in the south of Cali, causing damage and three injuries.
• 24 April – In the nearby town of Palmira, Valle, an army base came under attack from cylinder bombs launched from a passing vehicle, no injuries were reported.
• 25 April – Two attackers launched grenades at a petrol station in Rozo, Valle, damaging vehicles.
• 25 April – A police station in the rural community of Potrerito, close to Jamundí, came under gunfire attack in the early hours of the morning.
• 25 April – In another morning attack, Aeronáutica Civil reported drones launching explosives against a hilltop air traffic station close to El Tambo (Cauca), damaging antennas and leaving the radar inoperative.
• 25 April – a chiva rural bus was hit by explosive charges while traveling on Route 25 near to Mercaderes, south of Popayan. Police reported several injured including a child but no deaths
• 26 April – four men were gunned down in a bar in Toro, Valle, between Cali and Pereira.

According to a tally by thinktank Indepaz, the Toro deaths were the 48^th massacre recorded in 2026. In Colombia a ‘massacre’ is defined by the intentional killing of three or more people at the same time.

This weekend’s attacks were typical of a return to terrorist tactics such as car bombs, motorbike bombs, drones dropping home-made explosives and other artisanal artefacts.

Saturday’s Cajibío attack was initially reported as a boobytrap bomb, or “IED” (Improvised Explosive Device) which are caches of high explosives buried by the roadside by rebel groups, usually aimed at passing military patrols

But later reports suggested the civilian vehicles were struck by a pipeta mortar. These are fashioned from household gas bottles and clumsily launched from mortars made of industrial piping.

Notoriously inaccurate, a pipetas have claimed many civilian lives in the Colombian conflict, most notably in the Chocó town of Bojayá in 2002 when a charge launched by FARC guerrillas struck a church killing 79 civilians sheltering inside.

Behind Saturday’s atrocity was alias ‘Marlon’ of the Estado Mayor Central (EMC), said Colombia’s defence minister of defence Pedro Sanchez. The state offered a reward of US$140,000 for information leading to his capture.

Original dissidents

Marlon, whose real name is Iván Idrobo, was formerly in the ranks of the FARC guerrillas where he trained as a bomb maker. He is now thought to lead the EMC’s Frente Jaime Martínez which according to the Defensoria del Pueblo controls the cocaine trade, illegal gold mining and extortion rackets around the town of Suárez in the northwest of Cauca.

The EMC, lead by former FARC chief Iván Mordico, has proven to be the most intransigent of the myriad of armed groups which the current Petro government has tried to broker peace with under his controversial Paz Total policy.

Seen as the “original” dissidents that rejected the partly successful peace process under former president Manual Santos in 2016, the EMC initially agreed to negotiate when Gustavo Petro came to power in 2022 but soon engaged in bitter infighting with rival armed groups creating a rupture with Paz Total.

For his part, Petro tweeted his disgust at the Cajibío attack and the EMC “narco-terrorists” behind it.

“The groups led by Iván Mordisco in Cauca are criminals who have committed crimes against humanity and must be treated as such,” he said.

Some pundits commented that Petro’s early treatment of the EMC as a political actor had given the armed group room to expand, contributing to the current security crisis. In the heat of next month’s elections, others turned their ire on presidential candidate Iván Cepeda, seen as an architect of Petro’s struggling peace plans.

Rival right-wing candidate Paloma Valencia accused Cepeda of his role in “tying the hands of state forces, the rampant increase in illicit crops, the historic numbers of massacres, and waves of violence like today’s”.

Valencia also rounded on Petro for posting photos of his birthday celebrations even as the country was reeling from the horrific footage of the Cauca bombing. “Show some respect,” she messaged.

Colombian President Gustavo Petro will meet Venezuela’s interim leader Delcy Rodríguez in Caracas on Friday to address security challenges along the shared border, marking their first official encounter since Nicolás Maduro was captured by U.S special forces on January 3, 2026.

The meeting, to be held at the Miraflores presidential palace, is expected to center on coordination between the two countries to tackle armed groups, drug trafficking and other cross-border threats that have long destabilized frontier regions.

Colombia’s presidency said the talks aim to “strengthen bilateral cooperation, territorial control and coordination on security matters,” following the cancellation of a previous meeting scheduled for March 13 at the border due to security concerns cited by Caracas.

Friday’s talks come after Rodríguez assumed power earlier this year following the capture of former Venezuelan dictator Nicolás Maduro during Operation Absolute Resolve.

Petro is expected to travel to Caracas after holding meetings earlier in Bogotá. The leaders will first hold a private discussion to outline joint actions addressing border instability, followed by a broader metting between their respective delegations aimed at formalizing institutional commitments.

Officials from both countries are also expected to sign the final act of the III Commission on Neighborhood and Integration, with foreign ministers participating, before delivering statements to the media.

The Colombia–Venezuela border stretches more than 2,200 kilometers (1,367 miles) from the Caribbean coast to the Amazon basin and has long been a hotspot for illegal activity, including the presence of the National Liberation Army (ELN) guerrilla, as well as drug trafficking and smuggling networks.

Petro said earlier this week that the talks would place particular emphasis on the Catatumbo region, one of the most volatile areas along the frontier, where violence linked to armed groups and illicit economies has intensified.

“If we go, Catatumbo is a key issue to discuss with President Delcy,” Petro said during a cabinet meeting on April 21, adding that his delegation would include military and police officials to coordinate security strategies.

He said the goal is to develop a joint security plan, improve coordination between the two countries’ armed forces and police, and deepen intelligence-sharing, warning that a lack of cooperation could lead to operations that harm civilian populations.

The meeting also comes against the backdrop of a rebound in bilateral trade between the two countries following years of strained relations.

Trade flows have increased significantly in recent years, rising from around US$200 million three years ago to more than $1 billion, representing an increase of roughly 600%, according to official figures.

Colombia recorded a trade surplus of US$1 billion with Venezuela in 2025, underscoring the economic incentives for both governments to maintain stable ties despite ongoing political uncertainties.

Petro first announced the trip last week during an interview in Spain, referencing the earlier failed meeting and signaling his willingness to travel to Caracas to advance talks.

The visit marks a key test of Colombia’s role in engaging with Venezuela’s transitional leadership, as both countries seek to stabilize their shared border while cautiously rebuilding diplomatic and economic relations in the post-Maduro era.

Crucial Santa Marta conference will include voices of communities long opposed to the exploitation of fossil fuels.

Thirty years ago, Colombia’s U’wa people were ready to commit mass suicide by jumping off a 500-meter cliff. The close-knit indigenous community would rather die with dignity than succumb to oil exploration on their ancestral land.

The U’wa announced their dilemma in 1995 in an open letter that ricocheted around the world. It was no empty threat: 400 years before their ancestors had jumped from the Alto de los Infieles (Cliff of the Infidels) rather than submit to the Spanish colonial yoke.

“The U’wa were the first to call oil the ‘blood of the earth’,” explains Kevin Koenig, director of climate and energy at Amazon Watch, a U.S.-based non-profit. “The U’wa were the first to say that oil needs to stay in the ground. They warned against its extraction and its impact on the world.”

Amazon Watch has supported the U’wa to resist extractive industries over the same three decades, along with dozens of other at-risk communities in Latin America.

This week, in a ground-breaking conference in Santa Marta, some of those efforts will come full circle at the first global summit on “Transitioning away from Fossil Fuels”.

The six-day conference, starting April 24, will host 50 country delegations plus dozens of civil society organizations.

This “road map towards renewable energy” is backed by the Fossil Fuel Treaty Initiative, an alliance of nation states, technical bodies, communities and individuals working to secure a “global just transition from coal, oil and gas”.

For the organizers the timing is critical with climate upset, fuel shortages, war in the Middle East and big oil’s sticky grip on geopolitics more exposed than ever. There’s never been a better moment to move to renewable energy.

A key part of the conference will be representation from indigenous communities; the U’wa, along with many others, will have a voice at the table.

Glacier gone

For Koenig, it is also significant that the inaugural meeting is in Colombia, one of the world’s most biodiverse countries, but also an oil producer moving to curb fossil fuels and embrace renewables.

There is further symmetry in the location: the small coastal city of Santa Marta is “just over the hill” from the U’wa territory which straddles the tropical glaciers of the El Cocuy mountain range, Koenig tells The Bogotá Post.

A hiking route over the same mountains is known as Colombia’s climate change trail – see the ice before it melts.

Prophetically, just three weeks before the conference’s kick-off, the IDEAM climate agency reported that a glacier in the heart of U’wa territory had melted for good.

“Satellite monitoring confirms that Los Cerros de la Plaza glacier coverage is today at zero square kilometers,” it announced matter-of-factly.

Living these realities gives indigenous communities such as the U’wa, wedded to nature and geography, a powerful voice in the transition from fossil fuels.

This experience has often come at a high cost, says Koenig. In countries like Colombia, particularly in the Amazon, oil companies are an existential threat to both the natural environment and the communities it supports. Drilling is invariably a catalyst for violence.

“Some countries use oil extraction as a reason to open areas, saying ‘we can militarize it and it will be safer’. In fact, oil and energy infrastructures are a magnet for armed groups, for political attacks or blackmail,” he explains.

Amazon Watch has supported many indigenous communities to resist oil companies in the Amazon regions of southern Colombia, Peru and Ecuador, often through practical means such as providing solar power and communications equipment, trainings and legal resources, but also by raising their voices to the outside world.

The organization’s latest report, The Amazon Under Siege, highlights how extractive industries and the armed groups that trail in their wake are putting Amazon communities in the crossfire.

Oil addiction

Colombia might have turned a corner with its oil moratorium in Amazon regions but neighboring countries are on a different path, one that might be summed up by U.S. president Donald Trump’s call to “drill, baby, drill”.

“Ecuador is going in the opposite direction with new oil auctions, and two new exploration blocks in remote rainforest,” says Koenig. Peru is following suit in jungle areas hitherto untouched. Perhaps not surprisingly, neither of the Andean countries is attending the Santa Marta transition conference.

According to Koenig, Peru and Ecuador are already in the throes of social violence but now risk replicating Colombia’s conflict with its rural oil pipelines that are constantly attacked or bombed, or oil lines tapped by fuel thieves, creating spills in biodiverse hotspots.

Added to that, drilling new wells makes little economic sense, he says. Current markets are signalling peak oil demand by 2030 even while wind and solar are taking a bigger share of energy output.

By doubling down on oil extraction both countries are “gambling with their future.” Aside from the moral and ethical issues of drilling in remote rainforest with indigenous peoples, getting banks to fund these ventures against the headwinds of renewables is not guaranteed.

“This is the moment where we are seeing both wars linked to fossil fuels politics and dependencies, but also for the first time renewables energies are not just theoretical, they are real, and decision-makers know they are scalable,” notes Koenig.

Fresh air

This seismic shift is reflected in the sassy subtext of the Santa Marta conference: climate deniers not invited. Meetings are reserved for a “coalition of the willing”, Colombian environment minister Irene Vélez, a key organizer of the event, told the Guardian this week..

For campaigners like Kevin Koenig this attitude is a breath of fresh air. Previous climate change conferences, run by the UN, have failed to pin global warming on big oil, he says.

“We know that fossil fuels are the number one source of carbon emissions but that’s nowhere to be found in the Paris [climate change] agreement. That’s due largely to the influence of the oil industry and lobbyists,” says Koenig.

Changing the narrative requires an alignment between traditional knowledge and science, he says. Indigenous communities, the original resisters, are now part of that with their wealth of experience.

Bogotá’s mayor has called for a major expansion of the city’s police force following a deadly knife attack on a television production set and a separate killing at a public transport station, as authorities warn of shifting patterns of urban crime in Colombia’s capital.

Carlos Fernando Galán said the city requires at least 8,000 additional police officers to effectively confront rising insecurity, after convening an extraordinary security council on Monday with senior officials from law enforcement, the military and prosecutors.

The move follows a shocking outbreak of violence on April 18 during the filming of the television series Sin senos sí hay paraíso in the central Santa Fe locality — an incident that left three people dead and several others injured.

“This is an extremely serious and senseless act of violence that hurts all of Bogotá,” Galán said, expressing solidarity with the victims’ families and the country’s audiovisual sector. “To respond effectively, we must strengthen the police, improve investigations, expand technological capabilities and increase personnel.”

The attack unfolded at approximately 3:30 p.m. in the Los Laches neighborhood, near the eastern edge of Parque Nacional, where a production crew had been filming in a public street close to the Instituto Roosevelt.

According to preliminary findings, a man not affiliated with the production approached the set and, without any prior interaction, attacked a crew member with a sharp weapon.

The sudden assault triggered panic and a rapid escalation of violence. Witnesses said several people at the scene intervened in an attempt to stop the attacker, leading to a chaotic street fight in which multiple individuals were stabbed.

In the ensuing struggle, the assailant managed to inflict severe injuries on several people before being subdued. Three individuals — including the attacker and two members of the production team — were transported to Hospital La Samaritana, where they later died from their wounds.

A fourth person injured in the confrontation was taken to Hospital Universitario San Ignacio. Authorities have not released further details regarding that individual’s condition.

The victims from the audiovisual team were identified as Henry Alberto Benavides Cárdenas, 45, and Nicolás Francisco Perdomo Corrales, 18.

Officials have stressed that the attack does not appear to be linked to robbery or organized crime. Instead, investigators are examining the background of the alleged assailant, who had previously been reported for threats and is believed to have a history of mental health issues — factors now under review by judicial and medical authorities.

The case has rattled Colombia’s cultural sector, which have grown steadily in recent years as Bogotá has positioned itself as a regional hub for film and television production. For many in the sector, the attack represents a deeply unsettling breach of safety for the industry.

Monday’s security meeting also addressed a separate killing that occurred in the city’s public transport system. A 19-year-old man, identified as Freddy Santiago Guzmán, died after being attacked during a robbery at the Minuto de Dios TransMilenio station.

Galán said the two incidents, while distinct, highlight the need for a more robust and coordinated security strategy across the capital. He called on the national government to provide greater support in terms of funding, personnel and institutional backing.

“We will not step back in the fight against crime,” he said. “But Bogotá cannot face this challenge alone.”

Security Secretary César Restrepo warned of what he described as a structural weakness in controlling the circulation of weapons, particularly knives and other bladed instruments.

“More than 10,000 bladed weapons have been seized so far this year,” Restrepo said, adding that the continued flow of such weapons into the city remains a critical concern for authorities.

Officials also pointed to evolving criminal dynamics that are complicating law enforcement efforts. Galán described the emergence of more fluid and decentralized forms of criminal activity, in which individuals come together temporarily to commit specific acts before dispersing.

“We are seeing a kind of ‘freelance’ crime,” he said. “This creates new challenges for intelligence work and policing.”

The extraordinary security council brought together representatives from the police, the army’s 13th Brigade of the Colombian Army and the Fiscalía General de la Nación, as authorities seek to strengthen coordination in response to recent violence.

Police commander Giovanni Cristancho Zambrano said officers had recovered eight stolen vehicles in the past week and urged citizens to report suspicious behaviour, particularly involving occupants of private vehicles, to support preventive action.

The rash of incidents during one weekend in the capital have sharpened concerns over public safety, especially in central districts where commercial, residential and cultural life converge in densely populated areas.

For the city’s growing audiovisual sector, the killings have raised urgent questions about security protocols for productions operating in open urban environments. Messages of mourning circulated widely among industry professionals, reflecting both grief and frustration over the circumstances surrounding the attack.

While city authorities have pledged to reinforce measures across key areas, Galán’s call for thousands more officers reveals the scale of Bogotá’s security needs as it grapples with entrenched crime from micro-trafficking groups and rapidly evolving new forms of urban violence.

Investigations into both incidents remain ongoing, with authorities working to establish the full sequence of events and any underlying factors that may have contributed to the attacks.
