The United States has imposed sanctions on a network of four people and four firms charged of hiring former Colombian soldiers to combat alongside and instruct a militia force in Sudan the United States claims of genocidal acts.

Group Makeup

Announcing the sanctions on this week, the American treasury stated the scheme was primarily made up of Colombian citizens and firms.

Scores of ex-soldiers from Colombia have been recruited to go to Sudan to combat beside the RSF paramilitary group, a force implicated in horrific war crimes including ethnically targeted slaughter and mass abductions.

Emergence of Involvement

The participation of ex-soldiers first came to light last year, prompted by an investigation which found that over three hundred former soldiers had been hired to engage in combat – an event that resulted in an unprecedented apology from the Colombian government.

Former Colombian military have historically been seen as highly prized fighters in conflict zones due to their considerable warzone knowledge acquired during decades of civil war, training on Nato equipment, and elite military instruction.

Reported Actions

In the Sudanese theater, the Colombians have allegedly instructed child soldiers, instructed militiamen in drone operation, and fought directly on the frontlines. One source previously stated that training children was "awful and crazy" but commented that "unfortunately that’s how war is".

Targeted Persons

Among those sanctioned was a dual national, a individual with dual citizenship and ex-soldier operating from the UAE. The Treasury alleged he played a central role in hiring and sending mercenaries to Sudan. His spouse, Claudia Viviana Oliveros Forero, was penalized as well.

Also on the penalty list was Duque Botero, a dual Colombian-Spanish citizen who authorities say ran a firm implicated in managing finances and payments for the recruitment operation. "In 2024 and 2025, American entities linked to Duque carried out several money transfers, amounting to millions," the government release noted.

Colombian national Mónica Muñoz Ucros was the final person to be sanctioned, with the firm she operated said to have conducted money transfers linked to Duque and his companies.

"The United States again calls on outside forces to halt the flow of financial and military support to the warring parties," the department said in a statement.

Analyst Commentary

An expert, senior analyst at the International Crisis Group, called the actions as a "highly important" development, stating that "targeting the enablers is the proper strategy".

It was also noted that, Bogotá ratified a piece of legislation endorsing the anti-mercenary convention, designed to limit its citizens' long history in foreign conflicts and transform domestic defense strategy.

Sean McFate, a scholar on the subject, advised additional measures, stating that "restrictions are needed but not enough for addressing rampant mercenarism".

"It’s an illicit economy and operating from the Emirates, which is largely insulated from sanctions," he commented. The Emirati government has been repeatedly implicated of arming the RSF, allegations it disputes. "This trend will probably continue," he advised.
