US Imposes Restrictions on Operation Accused of Recruiting South American Mercenaries to Sudan.

The Washington has levied restrictions on a operation of four individuals and four companies charged of enlisting former Colombian soldiers to fight for and train a militia force in Sudan which the US alleges of acts of genocide.

Network Composition

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

Numerous of ex-soldiers from Colombia have reportedly travelled to the conflict in Sudan to operate with the Sudanese RSF militia, a faction linked to terrible atrocities such as ethnically targeted slaughter and mass abductions.

Discovery of Participation

The involvement of Colombian fighters first came to light in 2024, after an investigation which disclosed that more than 300 former soldiers had been hired to fight – an revelation that led to an unusual statement of regret from officials in Bogotá.

Former Colombian military have historically been seen as among the world’s most sought-after mercenaries due to their vast combat experience gleaned from a long-running domestic war, training on advanced weaponry, and superior tactical education.

Reported Actions

In the Sudanese theater, the contractors have reportedly trained child soldiers, taught fighters to pilot drones, and participated in direct battles. A mercenary was quoted as saying that working with child soldiers was "terrible and insane" but commented that "unfortunately that’s how war is".

Named Entities

Among those targeted was a dual national, a individual with dual citizenship and ex-soldier operating from the UAE. The Treasury alleged he played a pivotal function in enlisting and transporting mercenaries to Sudan. His spouse, Claudia Oliveros, was penalized as well.

Also on the sanctions list was Mateo Andrés Duque Botero, a individual with Colombian and Spanish citizenship who the Treasury stated ran a firm implicated in managing finances and payments for the network. "In 2024 and 2025, American entities connected to Duque carried out multiple financial transactions, totalling millions of US dollars," the official announcement noted.

Colombian national Mónica Muñoz Ucros was the fourth individual to be sanctioned, with the entity she oversaw said to have conducted wire transfers associated with Duque and his companies.

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

Reaction

An expert, from a conflict think tank, described the actions as a "highly important" milestone, stating that "calling out those who are doing the contracting is the right way to go".

She added that, Bogotá ratified a statute approving the anti-mercenary convention, designed to limit decades of Colombian involvement in international fights and change its security approach.

Another expert, a scholar on the subject, urged more caution, saying that "penalties are required yet incomplete for dealing with rampant mercenarism".

"It operates in the black market and based out of Dubai, which is relatively sanction-proof," he commented. The Emirati government has been widely accused of arming the RSF, claims it rejects. "This trend will probably continue," he advised.
