The United States has imposed sanctions on a network of several persons and entities accused of enlisting Colombian mercenaries to combat alongside and instruct a Sudanese paramilitary group that Washington accuses of acts of genocide.

Network Composition

Announcing the restrictions on Tuesday, the Treasury stated the operation was mostly comprised of Colombian citizens and firms.

Hundreds of former Colombian military personnel have been recruited to go to Sudan to operate with the Sudanese RSF militia, a force implicated in terrible atrocities encompassing targeted ethnic killings and mass abductions.

Emergence of Involvement

The participation of ex-soldiers first came to light in 2024, after an report which disclosed that more than 300 ex-military personnel had been contracted to engage in combat – an discovery that prompted an rare mea culpa from Colombia’s foreign ministry.

These South American veterans have historically been seen as among the world’s most sought-after mercenaries due to their considerable warzone knowledge acquired during years of internal conflict, knowledge of Western military gear, and high-level combat training.

Role in the Conflict

In Sudan, the mercenaries have reportedly trained minors, provided drone warfare training, and participated in direct battles. A mercenary previously stated that working with child soldiers was "terrible and insane" but commented that "sadly, that is the nature of conflict".

Named Entities

Among those targeted was a retired Colombian officer, a citizen of both Colombia and Italy and retired Colombian military officer operating from the Dubai. The US authorities accused him a central role in hiring and sending ex-military personnel to Sudan. His spouse, Claudia Oliveros, was penalized as well.

Also on the restricted list was Mateo Duque Botero, a dual national who authorities say ran a firm linked to processing money and salaries for the scheme. "Recently, American entities linked to Duque engaged in numerous wire transfers, worth millions," the government release said.

Colombian national Mónica Muñoz Ucros was the other individual to be sanctioned, with the entity she oversaw accused of money transfers linked to Duque and his operations.

"Washington reiterates its demand for external actors to halt the flow of funding and arms to the warring parties," the Treasury announced.

Analyst Commentary

An expert, senior analyst at the International Crisis Group, described the measures as a "highly important" step, stating that "targeting the enablers is the proper strategy".

Furthermore, Colombia ratified a law endorsing the International Convention Against the Recruitment and Use of Mercenaries, aiming to curb decades of Colombian involvement in international fights and transform national security policy.

Another expert, a scholar on the subject, urged more caution, saying that "sanctions are necessary but insufficient for dealing with rampant mercenarism".

"It’s an illicit economy and based out of the UAE, which is difficult to penalize," he commented. The Emirati government has been widely accused of arming the RSF, allegations it disputes. "This trend will probably continue," McFate warned.
