The United States has enforced penalties on a operation of four individuals and four companies charged of enlisting Colombian mercenaries to combat alongside and instruct a armed faction in Sudan which the US alleges of committing genocide.

Network Composition

Revealing the sanctions on Tuesday, the US Treasury Department stated the scheme was largely composed of Colombian citizens and firms.

Scores of retired Colombian troops have reportedly travelled to Sudan to operate with the Sudanese RSF militia, a faction implicated in severe violations such as ethnically targeted slaughter and widespread kidnappings.

Discovery of Participation

The participation of ex-soldiers initially emerged in 2024, following an inquiry which found that more than 300 former soldiers had been hired to fight – an event that led to an unprecedented apology from Colombia’s foreign ministry.

Former Colombian military have widely regarded as some of the most in-demand contractors globally due to their extensive battlefield experience acquired during a long-running domestic war, training on advanced weaponry, and elite military instruction.

Reported Actions

In the conflict, the contractors have allegedly instructed underage fighters, instructed militiamen in drone operation, and engaged in frontline combat. One source previously stated that working with child soldiers was "horrific and irrational" but noted that "regrettably, war operates that way".

Sanctioned Individuals

Among those penalized was Álvaro Andrés Quijano Becerra, a dual Colombian-Italian national and retired Colombian military officer operating from the Dubai. The US authorities alleged he played a pivotal function in recruiting and deploying ex-military personnel to Sudan. His wife, Claudia Viviana Oliveros Forero, was also sanctioned.

Also on the restricted list was Mateo Andrés Duque Botero, a individual with Colombian and Spanish citizenship who authorities say managed a business implicated in handling funds and payroll for the network. "Over the past two years, US-based firms associated with Duque carried out numerous wire transfers, amounting to millions," the Treasury statement stated.

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

"The US once more urges external actors to stop giving monetary and weaponry aid to the combatants," the agency said in a statement.

Expert Analysis

An expert, senior analyst at the International Crisis Group, described the sanctions as a "very significant" development, saying that "calling out those who are doing the contracting is the right way to go".

It was also noted that, Colombia ratified a piece of legislation endorsing the global treaty against mercenarism, seeking to reduce its citizens' long history in foreign conflicts and transform national security policy.

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

"It’s an illicit economy and based out of the UAE, which is relatively sanction-proof," he commented. The United Arab Emirates has been frequently alleged of providing arms to the militia, claims it rejects. "More contractors from Colombia are likely," McFate warned.
