The United States has imposed sanctions on a network of several persons and entities alleged of hiring South American contractors to combat alongside and instruct a militia force in Sudan which the US alleges of genocidal acts.
Disclosing the sanctions on this week, the American treasury stated the operation was primarily made up of individuals and businesses from Colombia.
Numerous of former Colombian military personnel have reportedly travelled to the Sudanese warzone to operate with the Rapid Support Forces (RSF), a group implicated in horrific war crimes encompassing massacres based on ethnicity and mass abductions.
The involvement of Colombian fighters first came to light in 2024, after an report which found that hundreds of former soldiers had been recruited to engage in combat – an discovery that resulted in an unprecedented apology from Colombia’s foreign ministry.
Former Colombian military have historically been seen as highly prized fighters in conflict zones due to their vast combat experience acquired during a long-running domestic war, knowledge of Western military gear, and superior tactical education.
In Sudan, the contractors have been accused of teaching child soldiers, provided drone warfare training, and fought directly on the frontlines. One source previously stated that working with child soldiers was "terrible and insane" but added that "unfortunately that’s how war is".
Among those penalized was a retired Colombian officer, a individual with dual citizenship and former army officer based in the United Arab Emirates. The US authorities alleged he played a key part in recruiting and deploying mercenaries to Sudan. His spouse, Claudia Oliveros, was also sanctioned.
Also on the restricted list was Duque Botero, a dual Colombian-Spanish citizen who authorities say oversaw a company implicated in managing finances and payments for the recruitment operation. "Recently, US-based firms linked to Duque conducted several money transfers, worth millions," the Treasury statement said.
Citizen of Colombia Mónica Muñoz was the final person to be sanctioned, with the firm she operated accused of money transfers connected to Duque and his businesses.
"Washington reiterates its demand for foreign parties to cease providing financial and military support to the combatants," the Treasury said in a statement.
An expert, from a conflict think tank, called the actions as a "major" milestone, stating that "targeting the enablers is the right way to go".
Furthermore, Colombia recently passed a law endorsing the International Convention Against the Recruitment and Use of Mercenaries, designed to limit decades of Colombian involvement in overseas wars and reshape domestic defense strategy.
Sean McFate, an expert on mercenaries, urged more caution, stating that "penalties are required yet incomplete for combating the growing mercenary trade".
"It operates in the black market and operating from the UAE, which is relatively sanction-proof," he stated. The United Arab Emirates has been repeatedly implicated of arming the RSF, an accusation it has denied. "This trend will probably continue," he advised.
