The US government has enforced penalties on a group of four individuals and four companies accused of hiring Colombian mercenaries to combat alongside and instruct a armed faction in Sudan that Washington accuses of acts of genocide.

Network Composition

Revealing the measures on this week, the Treasury stated the operation was primarily made up of Colombian nationals and companies.

Scores of ex-soldiers from Colombia have been recruited to go to Sudan to combat beside the RSF paramilitary group, a group linked to severe violations including targeted ethnic killings and widespread kidnappings.

Discovery of Participation

The participation of ex-soldiers was first uncovered in 2024, following an report which found that more than 300 ex-military personnel had been contracted to participate in the war – an event that prompted an unprecedented apology from officials in Bogotá.

These South American veterans have widely regarded as some of the most in-demand contractors globally due to their extensive battlefield experience resulting from a long-running domestic war, training on advanced weaponry, and elite military instruction.

Role in the Conflict

In the Sudanese theater, the Colombians have allegedly instructed child soldiers, taught fighters to pilot drones, and engaged in frontline combat. An individual involved previously stated that instructing minors was "terrible and insane" but noted that "sadly, that is the nature of conflict".

Named Entities

Among those sanctioned was a retired Colombian officer, a individual with dual citizenship and former army officer operating from the United Arab Emirates. The government said he had a key part in enlisting and transporting ex-military personnel to Sudan. His spouse, Claudia Oliveros, was also sanctioned.

Also on the restricted list was Mateo Andrés Duque Botero, a individual with Colombian and Spanish citizenship who officials alleged oversaw a company implicated in processing money and salaries for the scheme. "Over the past two years, companies in the United States associated with Duque carried out numerous wire transfers, worth millions," the government release noted.

Individual Mónica Muñoz Ucros was the final person to be penalized, with the firm she operated said to have conducted money transfers associated with Duque and his operations.

"Washington reiterates its demand for foreign parties to halt the flow of funding and arms to the combatants," the agency stated.

Analyst Commentary

An expert, senior analyst at the International Crisis Group, called the sanctions as a "highly important" milestone, saying that "calling out those who are doing the contracting is the right way to go".

It was also noted that, Colombia has enacted a statute ratifying the anti-mercenary convention, seeking to reduce years of participation by its nationals in international fights and transform domestic defense strategy.

Another expert, a scholar on the subject, urged more caution, noting that "penalties are required yet incomplete for combating rampant mercenarism".

"This is a shadow economy and centered in the Emirates, which is largely insulated from sanctions," he said. The Emirati government has been widely accused of providing arms to the militia, claims it rejects. "This trend will probably continue," he advised.
