The Washington has enforced penalties on a group of four people and four firms alleged of enlisting Colombian mercenaries to combat alongside and instruct a militia force in Sudan which the US alleges of acts of genocide.

Group Makeup

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

Scores of retired Colombian troops have reportedly travelled to Sudan to combat beside the Rapid Support Forces (RSF), a group implicated in horrific war crimes such as massacres based on ethnicity and mass abductions.

Discovery of Participation

The role of these mercenaries was first uncovered in 2024, after an investigation which found that more than 300 former soldiers had been hired to participate in the war – an discovery that led to an unprecedented apology from Colombia’s foreign ministry.

Colombian ex-soldiers have historically been seen as highly prized fighters in conflict zones due to their considerable warzone knowledge gleaned from decades of civil war, training on advanced weaponry, and superior tactical education.

Reported Actions

In the Sudanese theater, the mercenaries have reportedly trained child soldiers, instructed militiamen in drone operation, and engaged in frontline combat. One source previously stated that instructing minors was "horrific and irrational" but noted that "unfortunately that’s how war is".

Named Entities

Among those penalized was a retired Colombian officer, a individual with dual citizenship and retired Colombian military officer based in the United Arab Emirates. The government said he had a pivotal function in hiring and sending mercenaries to Sudan. His wife, Claudia Viviana Oliveros Forero, was penalized as well.

Also on the restricted list was Mateo Andrés Duque Botero, a dual national who the Treasury stated oversaw a company linked to processing money and salaries for the recruitment operation. "Recently, US-based firms connected to Duque engaged in multiple financial transactions, totalling millions of US dollars," the official announcement stated.

Citizen of Colombia Mónica Muñoz was the other individual to be sanctioned, with the entity she oversaw alleged to have financial transactions associated with Duque and his companies.

"Washington reiterates its demand for foreign parties to halt the flow of funding and arms to the combatants," the department said in a statement.

Analyst Commentary

A senior analyst, senior analyst at the International Crisis Group, described the sanctions as a "major" milestone, saying that "identifying the recruiters is the correct approach".

She added that, the Colombian government recently passed a piece of legislation ratifying the global treaty against mercenarism, seeking to reduce its citizens' long history in overseas wars and reshape its security approach.

A mercenary specialist, a authority on private military contractors, advised additional measures, saying that "sanctions are necessary but insufficient for addressing widespread use of contractors".

"It operates in the black market and operating from Dubai, which is largely insulated from sanctions," he stated. The United Arab Emirates has been widely accused of supplying weapons to the paramilitary group, claims it rejects. "This trend will probably continue," the expert cautioned.
