United States Enforces Restrictions on Operation Accused of Funneling Colombian Contractors to the Sudanese Conflict.

The US government has levied restrictions on a group of four people and four firms alleged of recruiting Colombian mercenaries to combat alongside and instruct a armed faction in Sudan that Washington accuses of genocidal acts.

Group Makeup

Disclosing the restrictions on Tuesday, the US Treasury Department stated the scheme was mostly comprised of Colombian citizens and firms.

Hundreds of ex-soldiers from Colombia have allegedly journeyed to the conflict in Sudan to combat beside the Sudanese RSF militia, a group implicated in horrific war crimes such as massacres based on ethnicity and large-scale abductions.

Discovery of Participation

The role of these mercenaries first came to light the previous year, prompted by an inquiry which disclosed that hundreds of retired troops had been recruited to participate in the war – an event that prompted an unusual statement of regret from Colombia’s foreign ministry.

Former Colombian military have long been considered as among the world’s most sought-after mercenaries due to their extensive battlefield experience resulting from years of internal conflict, familiarity with advanced weaponry, and elite military instruction.

Role in the Conflict

In the conflict, the contractors have allegedly instructed underage fighters, instructed militiamen in drone operation, and engaged in frontline combat. One source previously stated that training children was "horrific and irrational" but commented that "regrettably, war operates that way".

Targeted Persons

Among those sanctioned was a dual national, a individual with dual citizenship and retired Colombian military officer based in the UAE. The government said he had a pivotal function in hiring and sending mercenaries to Sudan. His wife, Claudia Oliveros, was also sanctioned.

Also on the sanctions list was Duque Botero, a individual with Colombian and Spanish citizenship who authorities say oversaw a company linked to processing money and salaries for the recruitment operation. "In 2024 and 2025, American entities associated with Duque carried out several money transfers, worth millions," the official announcement noted.

Citizen of Colombia Mónica Muñoz was the other individual to be penalized, with the firm she operated said to have conducted money transfers linked to Duque and his businesses.

"Washington reiterates its demand for external actors to cease providing financial and military support to the combatants," the Treasury announced.

Analyst Commentary

An expert, from a conflict think tank, labeled the actions as a "very significant" milestone, noting that "targeting the enablers is the correct approach".

Furthermore, Colombia recently passed a piece of legislation approving the global treaty against mercenarism, designed to limit decades of Colombian involvement in foreign conflicts and transform its security approach.

Sean McFate, a scholar on the subject, urged more caution, noting that "restrictions are needed but not enough for addressing rampant mercenarism".

"This is a shadow economy and operating from the Emirates, which is largely insulated from sanctions," he stated. The UAE has been repeatedly implicated of providing arms to the militia, an accusation it has denied. "More contractors from Colombia are likely," the expert cautioned.
