The Washington has enforced penalties on a group of four individuals and four companies alleged of enlisting Colombian mercenaries to support and educate a Sudanese paramilitary group which the US alleges of committing genocide.

Network Composition

Disclosing the measures on Tuesday, the American treasury stated the network was mostly comprised of Colombian citizens and firms.

Hundreds of ex-soldiers from Colombia have been recruited to go to Sudan to combat beside the Sudanese RSF militia, a faction implicated in horrific war crimes encompassing targeted ethnic killings and mass abductions.

Emergence of Involvement

The role of these mercenaries initially emerged in 2024, after an report which disclosed that more than 300 ex-military personnel had been hired to engage in combat – an revelation that prompted an rare mea culpa from officials in Bogotá.

These South American veterans have widely regarded as highly prized fighters in conflict zones due to their considerable warzone knowledge acquired during years of internal conflict, training on Western military gear, and elite military instruction.

Reported Actions

In Sudan, the mercenaries have reportedly trained minors, provided drone warfare training, and participated in direct battles. One source remarked that training children was "awful and crazy" but noted that "regrettably, war operates that way".

Targeted Persons

Among those penalized was a retired Colombian officer, a dual Colombian-Italian national and ex-soldier operating from the UAE. The US authorities alleged he played a pivotal function in recruiting and deploying ex-military personnel to Sudan. His wife, Claudia Viviana Oliveros Forero, was penalized as well.

Also on the penalty 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 recruitment operation. "In 2024 and 2025, American entities connected to Duque engaged in several money transfers, worth millions," the Treasury statement stated.

Colombian national Mónica Muñoz was the final person to be targeted, with the firm she operated said to have conducted money transfers associated with Duque and his businesses.

"Washington reiterates its demand for foreign parties to stop giving funding and arms to the belligerents," the Treasury stated.

Analyst Commentary

An expert, with the International Crisis Group, called the measures as a "major" milestone, stating that "targeting the enablers is the correct approach".

She added that, Colombia recently passed a law endorsing the anti-mercenary convention, seeking to reduce years of participation by its nationals in foreign conflicts and change national security policy.

A mercenary specialist, a authority on private military contractors, called for greater wariness, stating that "penalties are required yet incomplete for addressing rampant mercenarism".

"It’s an illicit economy and based out of the Emirates, which is relatively sanction-proof," he commented. The Emirati government has been widely accused of arming the RSF, allegations it disputes. "This trend will probably continue," the expert cautioned.
