The Washington has enforced penalties on a network of several persons and entities alleged of recruiting South American contractors to combat alongside and instruct a militia force in Sudan the United States claims of committing genocide.

Group Makeup

Disclosing the measures on this week, the US Treasury Department stated the scheme was largely composed of individuals and businesses from Colombia.

Hundreds of ex-soldiers from Colombia have allegedly journeyed to Sudan to operate with the RSF paramilitary group, a group linked to severe violations encompassing targeted ethnic killings and widespread kidnappings.

Revelation of Role

The involvement of Colombian fighters was first uncovered last year, prompted by an investigation which found that over three hundred retired troops had been contracted to engage in combat – an event that resulted in an unusual statement of regret from the Colombian government.

These South American veterans have long been considered as some of the most in-demand contractors globally due to their extensive battlefield experience acquired during years of internal conflict, familiarity with Western military gear, and elite military instruction.

Role in the Conflict

In the conflict, the Colombians have been accused of teaching underage fighters, instructed militiamen in drone operation, and participated in direct battles. One source previously stated that working with child soldiers was "horrific and irrational" but commented that "sadly, that is the nature of conflict".

Named Entities

Among those penalized was a retired Colombian officer, a dual Colombian-Italian national and ex-soldier based in the UAE. The US authorities said he had a central role in enlisting and transporting mercenaries to Sudan. His wife, Claudia Oliveros, was penalized as well.

Also on the penalty list was Mateo Andrés Duque Botero, a individual with Colombian and Spanish citizenship who officials alleged managed a business accused of managing finances and payments for the scheme. "In 2024 and 2025, American entities linked to Duque carried out numerous wire transfers, totalling millions of US dollars," the official announcement stated.

Individual Mónica Muñoz Ucros was the fourth individual to be sanctioned, with the firm she operated alleged to have wire transfers associated with Duque and his companies.

"Washington reiterates its demand for external actors to halt the flow of financial and military support to the belligerents," the agency said in a statement.

Analyst Commentary

An expert, from a conflict think tank, described the sanctions as a "highly important" development, saying that "identifying the recruiters is the correct approach".

It was also noted that, the Colombian government recently passed a piece of legislation endorsing the global treaty against mercenarism, designed to limit its citizens' long history in international fights and transform national security policy.

A mercenary specialist, an expert on mercenaries, urged more caution, saying that "sanctions are necessary but insufficient for addressing widespread use of contractors".

"It operates in the black market and based out of the Emirates, which is relatively sanction-proof," he said. The United Arab Emirates has been repeatedly implicated of providing arms to the militia, claims it rejects. "This trend will probably continue," McFate warned.
