United States Enforces Penalties on Network Alleged of Recruiting South American Fighters to the Sudanese Conflict.

The United States has imposed sanctions on a network of four people and four firms accused of hiring Colombian mercenaries to combat alongside and instruct a Sudanese paramilitary group the United States claims of genocidal acts.

Operation Structure

Revealing the restrictions on this week, the Treasury stated the scheme was mostly comprised of Colombian nationals and companies.

Scores of former Colombian military personnel have been recruited to go to the conflict in Sudan to fight alongside the RSF paramilitary group, a group accused of terrible atrocities including targeted ethnic killings and widespread kidnappings.

Emergence of Involvement

The role of these mercenaries first came to light the previous year, prompted by an inquiry which revealed that hundreds of ex-military personnel had been hired to engage in combat – an event that led to an unprecedented apology from the Colombian government.

Former Colombian military have long been considered as among the world’s most sought-after mercenaries due to their considerable warzone knowledge resulting from decades of civil war, training on Western military gear, and superior tactical education.

Reported Actions

In the conflict, the contractors have been accused of teaching underage fighters, taught fighters to pilot drones, and engaged in frontline combat. An individual involved remarked that training children was "horrific and irrational" but commented that "sadly, that is the nature of conflict".

Sanctioned Individuals

Among those sanctioned was a retired Colombian officer, a individual with dual citizenship and former army officer operating from the Dubai. The US authorities said he had a pivotal function in hiring and sending former Colombian soldiers to Sudan. His wife, Claudia Oliveros, was penalized as well.

Also on the restricted list was Duque Botero, a dual Colombian-Spanish citizen who the Treasury stated managed a business implicated in managing finances and payments for the scheme. "In 2024 and 2025, US-based firms linked to Duque engaged in several money transfers, amounting to millions," the Treasury statement said.

Colombian national Mónica Muñoz was the final person to be sanctioned, with the firm she operated accused of financial transactions associated with Duque and his operations.

"Washington reiterates its demand for external actors to cease providing funding and arms to the belligerents," the department stated.

Analyst Commentary

An expert, from a conflict think tank, described the sanctions as a "very significant" milestone, saying that "targeting the enablers is the correct approach".

She added that, Colombia ratified a piece of legislation approving the global treaty against mercenarism, designed to limit years of participation by its nationals in overseas wars and transform its security approach.

Sean McFate, a scholar on the subject, urged more caution, saying that "restrictions are needed but not enough for dealing with widespread use of contractors".

"It operates in the black market and based out of the UAE, which is difficult to penalize," he said. The Emirati government has been frequently alleged of arming the RSF, an accusation it has denied. "This trend will probably continue," the expert cautioned.
