The Washington has imposed sanctions on a network of four individuals and four companies accused of enlisting South American contractors to fight for and train a Sudanese paramilitary group which the US alleges of genocidal acts.
Disclosing the measures on this week, the American treasury stated the operation was primarily made up of Colombian citizens and firms.
Numerous of retired Colombian troops have reportedly travelled to the conflict in Sudan to fight alongside the Rapid Support Forces (RSF), a force accused of terrible atrocities encompassing ethnically targeted slaughter and large-scale abductions.
The involvement of Colombian fighters initially emerged last year, after an investigation which disclosed that more than 300 former soldiers had been contracted to fight – an event that prompted an unprecedented apology from Colombia’s foreign ministry.
These South American veterans have historically been seen as some of the most in-demand contractors globally due to their vast combat experience acquired during a long-running domestic war, training on Nato equipment, and high-level combat training.
In Sudan, the mercenaries have reportedly trained underage fighters, instructed militiamen in drone operation, and participated in direct battles. An individual involved previously stated that working with child soldiers was "horrific and irrational" but added that "regrettably, war operates that way".
Among those penalized was a retired Colombian officer, a individual with dual citizenship and retired Colombian military officer located in the Dubai. The US authorities accused him a key part in hiring and sending former Colombian soldiers to Sudan. His wife, Claudia Oliveros, was similarly targeted.
Also on the penalty list was Mateo Duque Botero, a individual with Colombian and Spanish citizenship who the Treasury stated oversaw a company linked to processing money and salaries for the network. "Over the past two years, US-based firms linked to Duque conducted multiple financial transactions, amounting to millions," the Treasury statement said.
Citizen of Colombia Mónica Muñoz was the fourth individual to be targeted, with the entity she oversaw said to have conducted wire transfers associated with Duque and his businesses.
"The US once more urges outside forces to cease providing funding and arms to the belligerents," the Treasury said in a statement.
An expert, with the International Crisis Group, labeled the sanctions as a "highly important" development, saying that "identifying the recruiters is the right way to go".
It was also noted that, Bogotá ratified a law ratifying the anti-mercenary convention, seeking to reduce years of participation by its nationals in foreign conflicts and transform national security policy.
Sean McFate, a scholar on the subject, advised additional measures, saying that "restrictions are needed but not enough for combating rampant mercenarism".
"It’s an illicit economy and centered in the UAE, which is difficult to penalize," he stated. The United Arab Emirates has been repeatedly implicated of providing arms to the militia, claims it rejects. "This trend will probably continue," McFate warned.
