The US government has imposed sanctions on a network of four people and four firms alleged of enlisting former Colombian soldiers to combat alongside and instruct a militia force in Sudan that Washington accuses of acts of genocide.
Disclosing the restrictions on this week, the American treasury stated the operation was largely composed of Colombian citizens and firms.
Scores of former Colombian military personnel have been recruited to go to the Sudanese warzone to operate with the Sudanese RSF militia, a faction implicated in terrible atrocities such as massacres based on ethnicity and widespread kidnappings.
The role of these mercenaries first came to light last year, prompted by an investigation which revealed that more than 300 former soldiers had been recruited to fight – an discovery that led to an unprecedented apology from Colombia’s foreign ministry.
Colombian ex-soldiers have historically been seen as some of the most in-demand contractors globally due to their extensive battlefield experience acquired during a long-running domestic war, knowledge of advanced weaponry, and elite military instruction.
In the conflict, the Colombians have allegedly instructed child soldiers, instructed militiamen in drone operation, and participated in direct battles. An individual involved was quoted as saying that training children was "awful and crazy" but added that "sadly, that is the nature of conflict".
Among those penalized was a dual national, a citizen of both Colombia and Italy and retired Colombian military officer operating from the Dubai. The Treasury accused him a pivotal function 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 Duque Botero, a individual with Colombian and Spanish citizenship who the Treasury stated managed a business linked to handling funds and payroll for the scheme. "In 2024 and 2025, American entities connected to Duque carried out numerous wire transfers, worth millions," the government release said.
Colombian national Mónica Muñoz was the fourth individual to be targeted, with the company she managed accused of financial transactions associated with Duque and his companies.
"The US once more urges external actors to cease providing funding and arms to the belligerents," the department stated.
A senior analyst, from a conflict think tank, labeled the measures as a "major" development, stating that "calling out those who are doing the contracting is the right way to go".
Furthermore, the Colombian government ratified a piece of legislation approving the global treaty against mercenarism, aiming to curb its citizens' long history in international fights and transform domestic defense strategy.
A mercenary specialist, a scholar on the subject, called for greater wariness, noting that "restrictions are needed but not enough for dealing with widespread use of contractors".
"This is a shadow economy and operating from Dubai, which is largely insulated from sanctions," he said. The Emirati government has been repeatedly implicated of supplying weapons to the paramilitary group, an accusation it has denied. "This trend will probably continue," he advised.
