The Washington has imposed sanctions on a network of four people and four firms accused of enlisting Colombian mercenaries to combat alongside and instruct a Sudanese paramilitary group that Washington accuses of genocidal acts.

Network Composition

Announcing the measures on this week, the American treasury stated the scheme was mostly comprised of Colombian nationals and companies.

Numerous of former Colombian military personnel have been recruited to go to Sudan to fight alongside the Sudanese RSF militia, a group implicated in horrific war crimes encompassing massacres based on ethnicity and mass abductions.

Discovery of Participation

The role of these mercenaries was first uncovered the previous year, following an investigation which disclosed that more than 300 ex-military personnel had been recruited to participate in the war – an discovery that led to an unprecedented apology from Colombia’s foreign ministry.

Former Colombian military have historically been seen as some of the most in-demand contractors globally due to their considerable warzone knowledge acquired during a long-running domestic war, knowledge of Nato equipment, and elite military instruction.

Role in the Conflict

In Sudan, the contractors have been accused of teaching minors, provided drone warfare training, and participated in direct battles. A mercenary previously stated that working with child soldiers was "terrible and insane" but noted that "regrettably, war operates that way".

Targeted Persons

Among those penalized was Álvaro Andrés Quijano Becerra, a dual Colombian-Italian national and retired Colombian military officer based in the UAE. The government accused him a key part in recruiting and deploying former Colombian soldiers to Sudan. His spouse, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the sanctions list was Duque Botero, a dual Colombian-Spanish citizen who the Treasury stated oversaw a company implicated in handling funds and payroll for the network. "In 2024 and 2025, companies in the United States linked to Duque conducted multiple financial transactions, amounting to millions," the official announcement stated.

Citizen of Colombia Mónica Muñoz was the final person to be sanctioned, with the entity she oversaw alleged to have money transfers linked to Duque and his companies.

"The US once more urges external actors to halt the flow of monetary and weaponry aid to the warring parties," the Treasury stated.

Analyst Commentary

A senior analyst, senior analyst at the International Crisis Group, called the actions as a "very significant" development, noting that "targeting the enablers is the right way to go".

Furthermore, Bogotá has enacted a statute approving the global treaty against mercenarism, seeking to reduce its citizens' long history in foreign conflicts and transform domestic defense strategy.

Sean McFate, a scholar on the subject, advised additional measures, saying that "sanctions are necessary but insufficient for addressing widespread use of contractors".

"This is a shadow economy and operating from the UAE, which is largely insulated from sanctions," he commented. The United Arab Emirates has been frequently alleged of arming the RSF, an accusation it has denied. "Expect more Colombian mercenaries," he advised.
