The Washington has imposed sanctions on a operation of four people and four firms charged of recruiting Colombian mercenaries to support and educate a armed faction in Sudan the United States claims of acts of genocide.
Announcing the sanctions on Tuesday, the American treasury stated the network was largely composed of Colombian citizens and firms.
Scores of ex-soldiers from Colombia have allegedly journeyed to Sudan to operate with the Sudanese RSF militia, a group accused of horrific war crimes including targeted ethnic killings and large-scale abductions.
The participation of ex-soldiers first came to light last year, after an investigation which found that more than 300 ex-military personnel had been contracted to engage in combat â an discovery that resulted in an unprecedented apology from the Colombian government.
These South American veterans have historically been seen as highly prized fighters in conflict zones due to their considerable warzone knowledge acquired during years of internal conflict, knowledge of Western military gear, and elite military instruction.
In the conflict, the contractors have been accused of teaching child soldiers, provided drone warfare training, and engaged in frontline combat. An individual involved previously stated that instructing minors was "terrible and insane" but commented that "sadly, that is the nature of conflict".
Among those penalized was Ălvaro AndrĂ©s Quijano Becerra, a dual Colombian-Italian national and former army officer based in the Dubai. The government accused him a key part in recruiting and deploying ex-military personnel to Sudan. His spouse, Claudia Oliveros, was penalized as well.
Also on the restricted list was Mateo Andrés Duque Botero, a individual with Colombian and Spanish citizenship who the Treasury stated ran a firm implicated in handling funds and payroll for the network. "Over the past two years, American entities associated with Duque engaged in numerous wire transfers, worth millions," the Treasury statement stated.
Citizen of Colombia Mónica Muñoz Ucros was the fourth individual to be targeted, with the company she managed accused of wire transfers associated with Duque and his businesses.
"The United States again calls on outside forces to stop giving financial and military support to the warring parties," the Treasury stated.
An expert, senior analyst at the International Crisis Group, called the measures as a "very significant" development, saying that "identifying the recruiters is the right way to go".
It was also noted that, Colombia recently passed a law endorsing the International Convention Against the Recruitment and Use of Mercenaries, aiming to curb years of participation by its nationals in foreign conflicts and transform domestic defense strategy.
Sean McFate, a scholar on the subject, urged more caution, noting that "sanctions are necessary but insufficient for addressing widespread use of contractors".
"It operates in the black market and centered in the UAE, which is relatively sanction-proof," he commented. The UAE has been repeatedly implicated of arming the RSF, an accusation it has denied. "Expect more Colombian mercenaries," the expert cautioned.
