The US government has enforced penalties on a operation of four individuals and four companies alleged of enlisting former Colombian soldiers to fight for and train a Sudanese paramilitary group that Washington accuses of acts of genocide.
Announcing the measures on this week, the American treasury stated the operation was primarily made up of individuals and businesses from Colombia.
Hundreds of former Colombian military personnel have been recruited to go to Sudan to fight alongside the Rapid Support Forces (RSF), a group linked to terrible atrocities encompassing targeted ethnic killings and large-scale abductions.
The involvement of Colombian fighters first came to light in 2024, prompted by an report which found that more than 300 former soldiers had been contracted to participate in the war – an discovery that led to an unusual statement of regret from Colombia’s foreign ministry.
Colombian ex-soldiers have historically been seen as some of the most in-demand contractors globally due to their considerable warzone knowledge gleaned from decades of civil war, training on Western military gear, and superior tactical education.
In the Sudanese theater, the mercenaries have reportedly trained underage fighters, provided drone warfare training, and engaged in frontline combat. A mercenary previously stated that working with child soldiers was "terrible and insane" but noted that "unfortunately that’s how war is".
Among those sanctioned was Álvaro Andrés Quijano Becerra, a citizen of both Colombia and Italy and former army officer based in the United Arab Emirates. The Treasury said he had a central role in recruiting and deploying mercenaries to Sudan. His spouse, Claudia Oliveros, was also sanctioned.
Also on the penalty list was Mateo Andrés Duque Botero, a dual national who officials alleged oversaw a company linked to managing finances and payments for the network. "In 2024 and 2025, companies in the United States linked to Duque engaged in numerous wire transfers, amounting to millions," the government release noted.
Colombian national Mónica Muñoz was the fourth individual to be penalized, with the firm she operated said to have conducted money transfers associated with Duque and his businesses.
"Washington reiterates its demand for outside forces to stop giving financial and military support to the combatants," the Treasury announced.
A senior analyst, from a conflict think tank, called the sanctions as a "major" milestone, stating that "calling out those who are doing the contracting is the right way to go".
Furthermore, Bogotá ratified a statute approving the anti-mercenary convention, seeking to reduce decades of Colombian involvement in overseas wars and reshape national security policy.
Another expert, a authority on private military contractors, urged more caution, stating that "restrictions are needed but not enough for combating rampant mercenarism".
"This is a shadow economy and centered in Dubai, which is largely insulated from sanctions," he commented. The United Arab Emirates has been repeatedly implicated of arming the RSF, allegations it disputes. "More contractors from Colombia are likely," McFate warned.
