The Washington has levied restrictions on a group of four people and four firms accused of enlisting Colombian mercenaries to combat alongside and instruct a Sudanese paramilitary group that Washington accuses of acts of genocide.
Revealing the measures on this week, the Treasury stated the network was largely composed of individuals and businesses from Colombia.
Scores of ex-soldiers from Colombia have been recruited to go to the Sudanese warzone to fight alongside the RSF paramilitary group, a group accused of terrible atrocities including ethnically targeted slaughter and mass abductions.
The participation of ex-soldiers was first uncovered in 2024, prompted by an investigation which disclosed that over three hundred retired troops had been hired to engage in combat – an event that resulted in an unusual statement of regret from the Colombian government.
These South American veterans have historically been seen as some of the most in-demand contractors globally due to their extensive battlefield experience acquired during years of internal conflict, knowledge of Western military gear, and elite military instruction.
In the Sudanese theater, the mercenaries have reportedly trained underage fighters, taught fighters to pilot drones, and engaged in frontline combat. A mercenary previously stated that training children was "horrific and irrational" but added that "sadly, that is the nature of conflict".
Among those penalized was a dual national, a individual with dual citizenship and retired Colombian military officer located in the United Arab Emirates. The US authorities alleged he played a pivotal function in recruiting and deploying ex-military personnel to Sudan. His wife, Claudia Viviana Oliveros Forero, was similarly targeted.
Also on the sanctions list was Duque Botero, a dual Colombian-Spanish citizen who the Treasury stated managed a business implicated in handling funds and payroll for the recruitment operation. "Recently, companies in the United States linked to Duque conducted multiple financial transactions, worth millions," the government release noted.
Citizen of Colombia Mónica Muñoz was the fourth individual to be penalized, with the entity she oversaw said to have conducted money transfers linked to Duque and his companies.
"The United States again calls on external actors to cease providing monetary and weaponry aid to the combatants," the department announced.
Elizabeth Dickinson, with the International Crisis Group, called the actions as a "major" step, saying that "targeting the enablers is the proper strategy".
Furthermore, Colombia has enacted a piece of legislation ratifying the global treaty against mercenarism, aiming to curb years of participation by its nationals in foreign conflicts and reshape domestic defense strategy.
A mercenary specialist, a authority on private military contractors, advised additional measures, noting that "sanctions are necessary but insufficient for combating rampant mercenarism".
"It operates in the black market and centered in the UAE, which is largely insulated from sanctions," he stated. The United Arab Emirates has been repeatedly implicated of supplying weapons to the paramilitary group, an accusation it has denied. "Expect more Colombian mercenaries," he advised.
