United States Enforces Penalties on Network Accused of Funneling South American Mercenaries to Sudan.

The US government has imposed sanctions on a network of four individuals and four companies alleged of recruiting Colombian mercenaries to combat alongside and instruct a Sudanese paramilitary group which the US alleges of genocidal acts.

Group Makeup

Announcing the sanctions on this week, the Treasury stated the scheme was largely composed of Colombian citizens and firms.

Scores of former Colombian military personnel have allegedly journeyed to the Sudanese warzone to combat beside the Rapid Support Forces (RSF), a group linked to severe violations such as ethnically targeted slaughter and widespread kidnappings.

Revelation of Role

The participation of ex-soldiers first came to light in 2024, following an investigation which found that more than 300 ex-military personnel had been hired to engage in combat – an event that resulted in an unprecedented apology from officials in Bogotá.

Colombian ex-soldiers have widely regarded as highly prized fighters in conflict zones due to their considerable warzone knowledge resulting from years of internal conflict, familiarity with Nato equipment, and superior tactical education.

Activities in Sudan

In Sudan, the Colombians have allegedly instructed child soldiers, taught fighters to pilot drones, and participated in direct battles. A mercenary was quoted as saying that training children was "awful and crazy" but added that "sadly, that is the nature of conflict".

Named Entities

Among those penalized was a retired Colombian officer, a individual with dual citizenship and former army officer based in the United Arab Emirates. The Treasury said he had a pivotal function in recruiting and deploying mercenaries to Sudan. His wife, Claudia Oliveros, was also sanctioned.

Also on the restricted list was Mateo Andrés Duque Botero, a dual Colombian-Spanish citizen who authorities say ran a firm implicated in processing money and salaries for the scheme. "Recently, US-based firms linked to Duque carried out numerous wire transfers, amounting to millions," the government release noted.

Individual Mónica Muñoz Ucros was the other individual to be sanctioned, with the firm she operated said to have conducted money transfers connected to Duque and his operations.

"Washington reiterates its demand for foreign parties to cease providing financial and military support to the warring parties," the agency stated.

Expert Analysis

An expert, from a conflict think tank, described the sanctions as a "highly important" milestone, saying that "targeting the enablers is the proper strategy".

It was also noted that, the Colombian government recently passed a piece of legislation endorsing the International Convention Against the Recruitment and Use of Mercenaries, seeking to reduce years of participation by its nationals in international fights and transform its security approach.

Another expert, a authority on private military contractors, advised additional measures, saying that "sanctions are necessary but insufficient for addressing the growing mercenary trade".

"It operates in the black market and based out of the Emirates, which is largely insulated from sanctions," he said. The UAE has been frequently alleged of arming the RSF, allegations it disputes. "More contractors from Colombia are likely," McFate warned.
