The United States has levied restrictions on a group of four people and four firms alleged of enlisting South American contractors to combat alongside and instruct a militia force in Sudan the United States claims of genocidal acts.
Announcing the restrictions on Tuesday, the American treasury stated the operation was mostly comprised of Colombian nationals and companies.
Hundreds of ex-soldiers from Colombia have been recruited to go to the Sudanese warzone to combat beside the Rapid Support Forces (RSF), a faction linked to severe violations including massacres based on ethnicity and widespread kidnappings.
The involvement of Colombian fighters first came to light last year, prompted by an inquiry which found that more than 300 ex-military personnel had been hired to fight – an discovery that led to an rare mea culpa from Colombia’s foreign ministry.
These South American veterans have long been considered as some of the most in-demand contractors globally due to their vast combat experience resulting from decades of civil war, knowledge of Western military gear, and elite military instruction.
In the conflict, the Colombians have been accused of teaching minors, taught fighters to pilot drones, and engaged in frontline combat. One source remarked that instructing minors was "awful and crazy" but added that "sadly, that is the nature of conflict".
Among those targeted was a retired Colombian officer, a individual with dual citizenship and former army officer operating from the United Arab Emirates. The US authorities accused him a central role in enlisting and transporting ex-military personnel to Sudan. His spouse, Claudia Viviana Oliveros Forero, was penalized as well.
Also on the sanctions list was Mateo Duque Botero, a individual with Colombian and Spanish citizenship who authorities say managed a business linked to processing money and salaries for the network. "Over the past two years, American entities linked to Duque carried out numerous wire transfers, amounting to millions," the Treasury statement stated.
Colombian national Mónica Muñoz Ucros was the final person to be sanctioned, with the entity she oversaw accused of money transfers linked to Duque and his operations.
"The US once more urges external actors to stop giving financial and military support to the belligerents," the department announced.
Elizabeth Dickinson, from a conflict think tank, called the actions as a "highly important" step, noting that "identifying the recruiters is the right way to go".
It was also noted that, Colombia has enacted a law approving the International Convention Against the Recruitment and Use of Mercenaries, seeking to reduce decades of Colombian involvement in international fights and transform its security approach.
Another expert, a authority on private military contractors, called for greater wariness, stating that "sanctions are necessary but insufficient for addressing the growing mercenary trade".
"This is a shadow economy and centered in the Emirates, which is relatively sanction-proof," he said. The Emirati government has been widely accused of arming the RSF, claims it rejects. "More contractors from Colombia are likely," McFate warned.
