The US government has enforced penalties on a group of four individuals and four companies accused of enlisting Colombian mercenaries to combat alongside and instruct a militia force in Sudan that Washington accuses of genocidal acts.
Revealing the measures on this week, the Treasury stated the scheme was mostly comprised of Colombian nationals and companies.
Hundreds of ex-soldiers from Colombia have reportedly travelled to the conflict in Sudan to fight alongside the Rapid Support Forces (RSF), a group accused of severe violations encompassing targeted ethnic killings and mass abductions.
The role of these mercenaries was first uncovered in 2024, after an report which found that more than 300 retired troops had been contracted to participate in the war – an discovery that led to an unprecedented apology from the Colombian government.
These South American veterans have widely regarded as some of the most in-demand contractors globally due to their considerable warzone knowledge gleaned from a long-running domestic war, training on Nato equipment, and elite military instruction.
In Sudan, the Colombians have reportedly trained child soldiers, provided drone warfare training, and participated in direct battles. An individual involved was quoted as saying that instructing minors was "horrific and irrational" but added that "sadly, that is the nature of conflict".
Among those penalized was a retired Colombian officer, a citizen of both Colombia and Italy and former army officer based in the United Arab Emirates. The government accused him a pivotal function in hiring and sending former Colombian soldiers to Sudan. His wife, Claudia Oliveros, was penalized as well.
Also on the sanctions list was Mateo Duque Botero, a individual with Colombian and Spanish citizenship who authorities say oversaw a company implicated in processing money and salaries for the recruitment operation. "Over the past two years, US-based firms associated with Duque conducted multiple financial transactions, totalling millions of US dollars," the official announcement stated.
Colombian national Mónica Muñoz Ucros was the other individual to be targeted, with the company she managed alleged to have wire transfers linked to Duque and his operations.
"Washington reiterates its demand for foreign parties to stop giving financial and military support to the belligerents," the department announced.
An expert, with the International Crisis Group, described the measures as a "very significant" step, saying that "targeting the enablers is the proper strategy".
It was also noted that, Colombia ratified a piece of legislation endorsing the anti-mercenary convention, seeking to reduce decades of Colombian involvement in international fights and reshape national security policy.
Sean McFate, a authority on private military contractors, called for greater wariness, saying that "restrictions are needed but not enough for addressing rampant mercenarism".
"It’s an illicit economy and operating from the Emirates, which is largely insulated from sanctions," he stated. The Emirati government has been frequently alleged of providing arms to the militia, an accusation it has denied. "More contractors from Colombia are likely," he advised.
