The United States has enforced penalties on a network of four individuals and four companies alleged of enlisting South American contractors to support and educate a militia force in Sudan the United States claims of genocidal acts.

Group Makeup

Disclosing the restrictions on Tuesday, the Treasury stated the scheme was largely composed of Colombian citizens and firms.

Scores of former Colombian military personnel have been recruited to go to Sudan to combat beside the Rapid Support Forces (RSF), a faction linked to terrible atrocities encompassing massacres based on ethnicity and mass abductions.

Emergence of Involvement

The participation of ex-soldiers initially emerged last year, prompted by an inquiry which found that over three hundred retired troops had been contracted to engage in combat – an revelation that led to an rare mea culpa from Colombia’s foreign ministry.

Colombian ex-soldiers have historically been seen as highly prized fighters in conflict zones due to their extensive battlefield experience acquired during years of internal conflict, knowledge of Western military gear, and elite military instruction.

Role in the Conflict

In the Sudanese theater, the Colombians have been accused of teaching underage fighters, provided drone warfare training, and fought directly on the frontlines. A mercenary was quoted as saying that working with child soldiers was "terrible and insane" but commented that "sadly, that is the nature of conflict".

Sanctioned Individuals

Among those sanctioned was Álvaro Andrés Quijano Becerra, a citizen of both Colombia and Italy and former army officer located in the United Arab Emirates. The US authorities alleged he played a central role in enlisting and transporting former Colombian soldiers to Sudan. His spouse, Claudia Viviana Oliveros Forero, was penalized as well.

Also on the penalty list was Mateo Duque Botero, a individual with Colombian and Spanish citizenship who authorities say managed a business accused of managing finances and payments for the scheme. "In 2024 and 2025, companies in the United States linked to Duque engaged in multiple financial transactions, worth millions," the Treasury statement said.

Individual Mónica Muñoz was the final person to be penalized, with the company she managed said to have conducted money transfers linked to Duque and his businesses.

"The United States again calls on foreign parties to cease providing funding and arms to the belligerents," the agency said in a statement.

Expert Analysis

An expert, with the International Crisis Group, called the sanctions as a "highly important" step, stating that "calling out those who are doing the contracting is the correct approach".

It was also noted that, Colombia has enacted a statute endorsing the International Convention Against the Recruitment and Use of Mercenaries, designed to limit decades of Colombian involvement in overseas wars and change its security approach.

Another expert, a authority on private military contractors, urged more caution, saying that "sanctions are necessary but insufficient for addressing the growing mercenary trade".

"It operates in the black market and centered in the UAE, which is largely insulated from sanctions," he commented. The Emirati government has been widely accused of providing arms to the militia, allegations it disputes. "More contractors from Colombia are likely," he advised.
