The United States has enforced penalties on a operation of several persons and entities alleged of enlisting South American contractors to fight for and train a Sudanese paramilitary group which the US alleges of acts of genocide.
Disclosing the restrictions on Tuesday, the US Treasury Department stated the operation was largely composed of individuals and businesses from Colombia.
Numerous of retired Colombian troops have allegedly journeyed to the Sudanese warzone to operate with the RSF paramilitary group, a group accused of severe violations including ethnically targeted slaughter and large-scale abductions.
The role of these mercenaries initially emerged in 2024, after an investigation which found that more than 300 ex-military personnel had been contracted to participate in the war – an discovery that led to an unusual statement of regret from the Colombian government.
These South American veterans have long been considered as highly prized fighters in conflict zones due to their extensive battlefield experience gleaned from a long-running domestic war, knowledge of Western military gear, and high-level combat training.
In Sudan, the contractors have allegedly instructed child soldiers, instructed militiamen in drone operation, and engaged in frontline combat. A mercenary was quoted as saying that training children was "terrible and insane" but added that "regrettably, war operates that way".
Among those sanctioned was a retired Colombian officer, a individual with dual citizenship and former army officer based in the UAE. The government accused him a key part in enlisting and transporting mercenaries to Sudan. His wife, Claudia Oliveros, was similarly targeted.
Also on the sanctions list was Mateo Andrés Duque Botero, a dual national who the Treasury stated oversaw a company implicated in handling funds and payroll for the scheme. "Over the past two years, US-based firms linked to Duque engaged in multiple financial transactions, worth millions," the official announcement noted.
Colombian national Mónica Muñoz was the final person to be targeted, with the entity she oversaw said to have conducted financial transactions connected to Duque and his businesses.
"The United States again calls on external actors to halt the flow of funding and arms to the belligerents," the department announced.
Elizabeth Dickinson, from a conflict think tank, described the sanctions as a "very significant" development, saying that "targeting the enablers is the proper strategy".
She added that, the Colombian government ratified a piece of legislation endorsing the anti-mercenary convention, seeking to reduce decades of Colombian involvement in overseas wars and reshape national security policy.
Another expert, a scholar on the subject, called for greater wariness, noting that "restrictions are needed but not enough for combating rampant mercenarism".
"It operates in the black market and based out of the Emirates, which is difficult to penalize," he stated. The Emirati government has been frequently alleged of providing arms to the militia, an accusation it has denied. "This trend will probably continue," he advised.
