Death toll climbs to 20 after devastating bomb attack on Colombian highway

A bombing on a major Colombian highway on Saturday has claimed 20 lives, with another 36 people sustaining injuries, including minors. The attack occurred on the Pan-American Highway in the Cauca region in southern Colombia.

Footage from the scene depicted destroyed vehicles and wreckage scattered across the roadway. Colombian President Gustavo Petro attributed responsibility for the blast to armed groups affiliated with breakaway factions of the Revolutionary Armed Forces of Colombia (Farc). Regional Governor Octavio Guzman characterized the bombing as the most severe assault on civilians in recent decades.

Government response

Petro took to social media to condemn those responsible, declaring:

"Those who carried out this attack... are terrorists, fascists and drug traffickers. I want our very best soldiers to confront them."

Guzman shared video documentation of the destruction on the same platform, showing overturned vehicles and a crater spanning approximately 200 metres in diameter. He stressed that the bombing appeared indiscriminate and called for greater national support, stating:

"Cauca cannot continue to face this barbarity alone."

Attack details

Sunday reports indicated that the fatalities comprised 15 women and five men. Eyewitnesses told news agencies that the explosion was so powerful it threw people several metres backward.

Defence Minister Pedro Arnulfo Sánchez disclosed that earlier that day, authorities had intercepted another bus laden with explosives in the Cauca region that failed to detonate. He attributed that attempted attack to members of a drug-trafficking organisation.

Broader context

The Cauca region has experienced a series of violent incidents since Friday, with the governor noting additional attacks including an assault on a military facility in Cali that resulted in two injuries. The latest violence emerges approximately one month before Colombia's presidential election scheduled for 31 May.

A 2016 peace agreement between Farc and the government resulted in the demobilisation of thousands of fighters, though some refused to disarm and formed dissident splinter groups. President Petro, himself a former guerrilla member, has pursued a contentious peace initiative aimed at various armed organisations, achieving intermittent truces and periods of reduced violence. However, his administration's attempts to initiate formal peace negotiations with dissident Farc factions have proven unsuccessful.

Multiple breakaway Farc organisations remain active throughout Colombia, many deeply engaged in narcotics trafficking. The presidential campaign has become divided along security lines, with left-wing candidate Iván Cepeda, backed by Petro, advocating for continued dialogue with insurgent groups, while right-wing contenders Paloma Valencia and Abelardo De la Espriella have pledged stricter military operations against armed factions.
