The United States has enforced penalties on a network of four individuals and four companies charged of enlisting former Colombian soldiers to fight for and train a armed faction in Sudan that Washington accuses of committing genocide.
Revealing the restrictions on this week, the Treasury stated the operation was largely composed of Colombian nationals and companies.
Scores of ex-soldiers from Colombia have allegedly journeyed to the conflict in Sudan to combat beside the Sudanese RSF militia, a faction linked to horrific war crimes such as massacres based on ethnicity and widespread kidnappings.
The involvement of Colombian fighters initially emerged the previous year, following an report which found that over three hundred former soldiers had been recruited to fight – an discovery that prompted an unusual statement of regret from officials in Bogotá.
Colombian ex-soldiers have widely regarded as among the world’s most sought-after mercenaries due to their extensive battlefield experience resulting from a long-running domestic war, familiarity with Nato equipment, and high-level combat training.
In Sudan, the Colombians have reportedly trained underage fighters, provided drone warfare training, and participated in direct battles. One source was quoted as saying that working with child soldiers was "awful and crazy" but commented that "unfortunately that’s how war is".
Among those targeted was a dual national, a citizen of both Colombia and Italy and ex-soldier located in the Dubai. The government said he had a pivotal function in recruiting and deploying mercenaries to Sudan. His wife, Claudia Oliveros, 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 implicated in processing money and salaries for the recruitment operation. "Recently, US-based firms connected to Duque conducted numerous wire transfers, amounting to millions," the official announcement stated.
Colombian national Mónica Muñoz was the final person to be targeted, with the firm she operated accused of money transfers associated with Duque and his businesses.
"The United States again calls on outside forces to cease providing monetary and weaponry aid to the warring parties," the Treasury said in a statement.
Elizabeth Dickinson, from a conflict think tank, called the measures as a "highly important" milestone, saying that "targeting the enablers is the right way to go".
She added that, Colombia recently passed a law approving the anti-mercenary convention, designed to limit its citizens' long history in foreign conflicts and transform national security policy.
A mercenary specialist, a scholar on the subject, called for greater wariness, saying that "sanctions are necessary but insufficient for combating the growing mercenary trade".
"It’s an illicit economy and based out of the Emirates, which is relatively sanction-proof," he said. The United Arab Emirates has been repeatedly implicated of supplying weapons to the paramilitary group, allegations it disputes. "This trend will probably continue," the expert cautioned.
