The US government has levied restrictions on a network of four people and four firms alleged of hiring former Colombian soldiers to combat alongside and instruct a Sudanese paramilitary group that Washington accuses of genocidal acts.
Disclosing the restrictions on Tuesday, the US Treasury Department stated the operation was mostly comprised of Colombian nationals and companies.
Scores of ex-soldiers from Colombia have reportedly travelled to the Sudanese warzone to combat beside the Sudanese RSF militia, a faction accused of severe violations encompassing ethnically targeted slaughter and widespread kidnappings.
The involvement of Colombian fighters initially emerged in 2024, following an report which revealed that hundreds of former soldiers had been recruited to engage in combat – an discovery that prompted an unusual statement of regret from officials in Bogotá.
Former Colombian military have historically been seen as some of the most in-demand contractors globally due to their vast combat experience resulting from years of internal conflict, training on Western military gear, and superior tactical education.
In Sudan, the Colombians have been accused of teaching minors, instructed militiamen in drone operation, and participated in direct battles. A mercenary was quoted as saying that working with child soldiers was "awful and crazy" but commented that "sadly, that is the nature of conflict".
Among those penalized was Álvaro Andrés Quijano Becerra, a dual Colombian-Italian national and former army officer operating from the Dubai. The Treasury alleged he played a pivotal function in enlisting and transporting mercenaries to Sudan. His wife, Claudia Viviana Oliveros Forero, was similarly targeted.
Also on the sanctions list was Mateo Andrés Duque Botero, a dual national who officials alleged oversaw a company linked to managing finances and payments for the network. "Recently, American entities associated with Duque conducted multiple financial transactions, totalling millions of US dollars," 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 United States again calls on external actors to cease providing funding and arms to the warring parties," the department said in a statement.
A senior analyst, with the International Crisis Group, called the actions as a "highly important" development, saying that "identifying the recruiters is the proper strategy".
It was also noted that, Colombia has enacted a statute endorsing the anti-mercenary convention, seeking to reduce decades of Colombian involvement in overseas wars and transform its security approach.
Sean McFate, a scholar on the subject, called for greater wariness, stating that "restrictions are needed but not enough for combating the growing mercenary trade".
"It operates in the black market and operating from Dubai, which is relatively sanction-proof," he commented. The United Arab Emirates has been frequently alleged of providing arms to the militia, allegations it disputes. "More contractors from Colombia are likely," he advised.
