The US government has enforced penalties on a group of four people and four firms alleged of enlisting South American contractors to fight for and train a armed faction in Sudan that Washington accuses of genocidal acts.

Network Composition

Revealing the restrictions on this week, the American treasury stated the network was largely composed of Colombian nationals and companies.

Numerous of retired Colombian troops have reportedly travelled to the conflict in Sudan to combat beside the Sudanese RSF militia, a group implicated in terrible atrocities encompassing ethnically targeted slaughter and mass abductions.

Emergence of Involvement

The role of these mercenaries was first uncovered last year, prompted by an report which revealed that hundreds of ex-military personnel had been contracted to fight – an event that prompted an unusual statement of regret from the Colombian government.

Former Colombian military have widely regarded as highly prized fighters in conflict zones due to their extensive battlefield experience acquired during years of internal conflict, knowledge of Nato equipment, and high-level combat training.

Reported Actions

In Sudan, the contractors have allegedly instructed child soldiers, taught fighters to pilot drones, and engaged in frontline combat. One source was quoted as saying that instructing minors was "terrible and insane" but noted that "sadly, that is the nature of conflict".

Targeted Persons

Among those penalized was a retired Colombian officer, a citizen of both Colombia and Italy and former army officer located in the United Arab Emirates. The US authorities said he had a central role in hiring and sending former Colombian soldiers to Sudan. His spouse, Claudia Oliveros, was also sanctioned.

Also on the penalty list was Duque Botero, a individual with Colombian and Spanish citizenship who authorities say oversaw a company accused of managing finances and payments for the recruitment operation. "In 2024 and 2025, companies in the United States linked to Duque conducted several money transfers, totalling millions of US dollars," the official announcement stated.

Colombian national Mónica Muñoz was the fourth individual to be penalized, with the entity she oversaw accused of financial transactions associated with Duque and his operations.

"Washington reiterates its demand for outside forces to halt the flow of funding and arms to the warring parties," the Treasury said in a statement.

Expert Analysis

An expert, with the International Crisis Group, described the sanctions as a "major" step, saying that "targeting the enablers is the right way to go".

It was also noted that, Colombia has enacted a piece of legislation ratifying the anti-mercenary convention, designed to limit decades of Colombian involvement in overseas wars and reshape domestic defense strategy.

Another expert, a authority on private military contractors, called for greater wariness, stating that "sanctions are necessary but insufficient for combating rampant mercenarism".

"This is a shadow economy and based out of Dubai, which is relatively sanction-proof," he commented. The UAE has been widely accused of arming the RSF, claims it rejects. "Expect more Colombian mercenaries," he advised.
