The Washington has enforced penalties on a operation of several persons and entities accused of hiring Colombian mercenaries to support and educate a militia force in Sudan which the US alleges of acts of genocide.
Revealing the restrictions on this week, the American treasury stated the operation was mostly comprised of Colombian nationals and companies.
Scores of ex-soldiers from Colombia have allegedly journeyed to Sudan to combat beside the RSF paramilitary group, a force implicated in severe violations such as ethnically targeted slaughter and mass abductions.
The participation of ex-soldiers first came to light in 2024, after an report which disclosed that more than 300 former soldiers had been hired to engage in combat – an event that led to an unusual statement of regret from the Colombian government.
Former Colombian military have widely regarded as some of the most in-demand contractors globally due to their vast combat experience gleaned from years of internal conflict, training on Western military gear, and superior tactical education.
In the Sudanese theater, the Colombians have been accused of teaching child soldiers, instructed militiamen in drone operation, and participated in direct battles. An individual involved remarked that training children was "terrible and insane" but noted that "unfortunately that’s how war is".
Among those sanctioned was a dual national, a dual Colombian-Italian national and ex-soldier located in the Dubai. The US authorities alleged he played a key part in hiring and sending former Colombian soldiers to Sudan. His wife, Claudia Oliveros, was also sanctioned.
Also on the restricted list was Duque Botero, a dual national who authorities say managed a business implicated in processing money and salaries for the network. "Over the past two years, companies in the United States associated with Duque carried out multiple financial transactions, amounting to millions," the official announcement noted.
Individual Mónica Muñoz Ucros was the final person to be sanctioned, with the company she managed accused of money transfers linked to Duque and his companies.
"Washington reiterates its demand for foreign parties to stop giving financial and military support to the belligerents," the Treasury announced.
An expert, with the International Crisis Group, described the actions as a "highly important" milestone, stating that "calling out those who are doing the contracting is the correct approach".
Furthermore, Bogotá ratified a statute ratifying the International Convention Against the Recruitment and Use of Mercenaries, aiming to curb years of participation by its nationals in international fights and transform domestic defense strategy.
Sean McFate, an expert on mercenaries, called for greater wariness, noting that "penalties are required yet incomplete for combating widespread use of contractors".
"It operates in the black market and operating from the Emirates, which is difficult to penalize," he said. The United Arab Emirates has been frequently alleged of providing arms to the militia, allegations it disputes. "More contractors from Colombia are likely," he advised.
