The US government has levied restrictions on a network of four people and four firms charged of enlisting former Colombian soldiers to support and educate a Sudanese paramilitary group the United States claims of acts of genocide.

Revealing the restrictions on this week, the American treasury stated the operation was primarily made up of individuals and businesses from Colombia.

Hundreds of retired Colombian troops have been recruited to go to Sudan to operate with the Sudanese RSF militia, a force implicated in severe violations encompassing massacres based on ethnicity and mass abductions.

Emergence of Involvement

The role of these mercenaries initially emerged in 2024, following an investigation which revealed that hundreds of former soldiers had been recruited to participate in the war – an event that prompted an unusual statement of regret from Colombia’s foreign ministry.

Former Colombian military have widely regarded as highly prized fighters in conflict zones due to their extensive battlefield experience resulting from years of internal conflict, familiarity with Western military gear, and elite military instruction.

Reported Actions

In Sudan, the Colombians have been accused of teaching minors, provided drone warfare training, and engaged in frontline combat. An individual involved remarked that working with child soldiers was "awful and crazy" but commented that "unfortunately that’s how war is".

Named Entities

Among those sanctioned was a retired Colombian officer, a individual with dual citizenship and former army officer based in the UAE. The government alleged he played a pivotal function in hiring and sending mercenaries to Sudan. His wife, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the penalty list was Mateo Andrés Duque Botero, a dual national who authorities say ran a firm linked to managing finances and payments for the scheme. "In 2024 and 2025, companies in the United States associated with Duque conducted several money transfers, worth millions," the Treasury statement noted.

Citizen of Colombia Mónica Muñoz was the final person to be penalized, with the company she managed alleged to have money transfers linked to Duque and his businesses.

"The US once more urges external actors to halt the flow of funding and arms to the warring parties," the agency announced.

Expert Analysis

Elizabeth Dickinson, from a conflict think tank, labeled the sanctions as a "major" development, stating that "identifying the recruiters is the proper strategy".

She added that, Colombia recently passed a piece of legislation approving the global treaty against mercenarism, seeking to reduce its citizens' long history in foreign conflicts and change national security policy.

Sean McFate, a authority on private military contractors, urged more caution, noting that "restrictions are needed but not enough for dealing with widespread use of contractors".

"This is a shadow economy and operating from Dubai, which is largely insulated from sanctions," he said. The United Arab Emirates has been widely accused of supplying weapons to the paramilitary group, allegations it disputes. "More contractors from Colombia are likely," the expert cautioned.
