United States Enforces Sanctions on Operation Accused of Funneling South American Fighters to Sudan.

The Washington has levied restrictions on a group of several persons and entities charged of enlisting South American contractors to fight for and train a armed faction in Sudan which the US alleges of genocidal acts.

Network Composition

Disclosing the measures on Tuesday, the American treasury stated the operation was largely composed of Colombian citizens and firms.

Hundreds of retired Colombian troops have allegedly journeyed to Sudan to combat beside the Rapid Support Forces (RSF), a faction implicated in horrific war crimes encompassing targeted ethnic killings and widespread kidnappings.

Discovery of Participation

The participation of ex-soldiers first came to light the previous year, after an report which revealed that more than 300 ex-military personnel had been contracted to engage in combat – an discovery that resulted in an unprecedented apology from Colombia’s foreign ministry.

Colombian ex-soldiers have widely regarded as some of the most in-demand contractors globally due to their vast combat experience gleaned from decades of civil war, knowledge of Western military gear, and elite military instruction.

Activities in Sudan

In the Sudanese theater, the Colombians have reportedly trained minors, instructed militiamen in drone operation, and participated in direct battles. One source was quoted as saying that training children was "awful and crazy" but added that "unfortunately that’s how war is".

Named Entities

Among those sanctioned was a dual national, a individual with dual citizenship and ex-soldier located in the Dubai. The government said he had a key part in enlisting and transporting mercenaries to Sudan. His wife, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the penalty list was Mateo Duque Botero, a dual Colombian-Spanish citizen who officials alleged ran a firm implicated in managing finances and payments for the scheme. "In 2024 and 2025, American entities associated with Duque conducted numerous wire transfers, totalling millions of US dollars," the government release said.

Colombian national Mónica Muñoz Ucros was the other individual to be penalized, with the company she managed accused of financial transactions associated with Duque and his operations.

"Washington reiterates its demand for outside forces to stop giving financial and military support to the warring parties," the Treasury said in a statement.

Expert Analysis

An expert, with the International Crisis Group, described the sanctions as a "highly important" development, saying that "identifying the recruiters is the right way to go".

Furthermore, Colombia ratified a piece of legislation approving the global treaty against mercenarism, designed to limit its citizens' long history in overseas wars and reshape its security approach.

Another expert, a authority on private military contractors, advised additional measures, noting that "penalties are required yet incomplete for addressing rampant mercenarism".

"This is a shadow economy and operating from Dubai, which is difficult to penalize," he stated. The UAE has been repeatedly implicated of arming the RSF, claims it rejects. "Expect more Colombian mercenaries," he advised.
