The Washington has enforced penalties on a group of four individuals and four companies alleged of enlisting Colombian mercenaries to support and educate a Sudanese paramilitary group the United States claims of committing genocide.
Announcing the sanctions on Tuesday, the Treasury stated the scheme was mostly comprised of individuals and businesses from Colombia.
Scores of retired Colombian troops have reportedly travelled to the conflict in Sudan to combat beside the Rapid Support Forces (RSF), a faction linked to terrible atrocities including massacres based on ethnicity and mass abductions.
The involvement of Colombian fighters first came to light last year, following an inquiry which revealed that over three hundred ex-military personnel had been contracted to participate in the war – an discovery that prompted an unusual statement of regret from officials in Bogotá.
Former Colombian military have long been considered as some of the most in-demand contractors globally due to their extensive battlefield experience resulting from decades of civil war, training on Nato equipment, and superior tactical education.
In Sudan, the contractors have allegedly instructed minors, provided drone warfare training, and engaged in frontline combat. A mercenary previously stated that instructing minors was "horrific and irrational" but noted that "regrettably, war operates that way".
Among those sanctioned was a retired Colombian officer, a dual Colombian-Italian national and former army officer located in the UAE. The government accused him a key part in hiring and sending mercenaries to Sudan. His spouse, Claudia Oliveros, was also sanctioned.
Also on the sanctions list was Mateo Andrés Duque Botero, a dual national who officials alleged oversaw a company linked to managing finances and payments for the recruitment operation. "Over the past two years, US-based firms linked to Duque engaged in numerous wire transfers, totalling millions of US dollars," the official announcement stated.
Individual Mónica Muñoz Ucros was the fourth individual to be penalized, with the entity she oversaw alleged to have wire transfers connected to Duque and his companies.
"The US once more urges foreign parties to cease providing funding and arms to the belligerents," the agency stated.
Elizabeth Dickinson, with the International Crisis Group, described the actions as a "highly important" development, saying that "calling out those who are doing the contracting is the proper strategy".
Furthermore, Bogotá ratified a statute ratifying the anti-mercenary convention, designed to limit decades of Colombian involvement in foreign conflicts and change domestic defense strategy.
A mercenary specialist, an expert on mercenaries, advised additional measures, saying that "restrictions are needed but not enough for addressing rampant mercenarism".
"It operates in the black market and centered in the UAE, which is relatively sanction-proof," he commented. The UAE has been frequently alleged of arming the RSF, an accusation it has denied. "More contractors from Colombia are likely," the expert cautioned.
