The Washington has enforced penalties on a network of four people and four firms accused of hiring Colombian mercenaries to support and educate a armed faction in Sudan the United States claims of committing genocide.
Announcing the measures on this week, the American treasury stated the network was primarily made up of individuals and businesses from Colombia.
Numerous of ex-soldiers from Colombia have allegedly journeyed to the Sudanese warzone to combat beside the Rapid Support Forces (RSF), a group linked to severe violations such as massacres based on ethnicity and large-scale abductions.
The involvement of Colombian fighters initially emerged in 2024, following an investigation which revealed that more than 300 ex-military personnel had been recruited to participate in the war – an revelation that prompted an unprecedented apology from officials in Bogotá.
Colombian ex-soldiers have historically been seen as among the world’s most sought-after mercenaries due to their extensive battlefield experience acquired during years of internal conflict, training on advanced weaponry, and superior tactical education.
In the Sudanese theater, the contractors have been accused of teaching underage fighters, taught fighters to pilot drones, and participated in direct battles. One source previously stated that working with child soldiers was "terrible and insane" but added that "sadly, that is the nature of conflict".
Among those penalized was Álvaro Andrés Quijano Becerra, a individual with dual citizenship and ex-soldier operating from the United Arab Emirates. The US authorities accused him a pivotal function in recruiting and deploying ex-military personnel to Sudan. His wife, Claudia Viviana Oliveros Forero, was also sanctioned.
Also on the restricted list was Duque Botero, a individual with Colombian and Spanish citizenship who officials alleged managed a business linked to managing finances and payments for the network. "Over the past two years, US-based firms associated with Duque carried out multiple financial transactions, amounting to millions," the Treasury statement noted.
Individual Mónica Muñoz Ucros was the final person to be targeted, with the firm she operated said to have conducted financial transactions connected to Duque and his operations.
"Washington reiterates its demand for external actors to halt the flow of monetary and weaponry aid to the belligerents," the Treasury said in a statement.
An expert, from a conflict think tank, labeled the measures as a "very significant" step, saying that "calling out those who are doing the contracting is the right way to go".
It was also noted that, Colombia recently passed a law ratifying the International Convention Against the Recruitment and Use of Mercenaries, seeking to reduce decades of Colombian involvement in overseas wars and change national security policy.
Sean McFate, an expert on mercenaries, called for greater wariness, saying that "restrictions are needed but not enough for addressing the growing mercenary trade".
"It’s an illicit economy and operating from the UAE, which is relatively sanction-proof," he commented. The UAE has been widely accused of arming the RSF, an accusation it has denied. "This trend will probably continue," the expert cautioned.
