Treasury’s Office of Foreign Assets Control (OFAC) said the sanctions target a Colombia-centered network that trained, transported, and financed personnel for the RSF, a group involved in some of the worst violence since Sudan’s civil war began in April 2023. The conflict has produced what US officials call the world’s most severe ongoing humanitarian crisis.
"Treasury is targeting a network that recruits fighters for the Rapid Support Forces,” said Under Secretary for Terrorism and Financial Intelligence John K. Hurley. “The RSF has shown again and again that it is willing to target civilians—including infants and young children. Its brutality has deepened the conflict and destabilized the region.”
According to OFAC, hundreds of former Colombian military members have traveled to Sudan since 2024 to serve as infantry, artillery operators, drone pilots, and instructors for the RSF.
Officials say some trainees included children. The fighters have taken part in battles across the country, including in Khartoum, Kordofan, Omdurman, and the siege of El Fasher. The RSF captured the city on October 26, 2025, after 18 months, and US officials say the group then carried out mass killings, torture, and sexual violence. The State Department determined in January that RSF members committed genocide.
OFAC identified retired Colombian officer Alvaro Andres Quijano Becerra, a dual Colombian-Italian national living in the UAE, as the central figure in the operation. Quijano allegedly used a network of companies, including the Bogota-based International Services Agency (A4SI) and Panama-based Global Staffing, to recruit personnel, channel payments, and obscure links to the RSF. The Treasury said A4SI advertised positions ranging from snipers to drone operators.
Another Colombia-based firm, Maine Global Corp, managed by dual Colombian-Spanish national Mateo Andres Duque Botero, allegedly moved funds and handled payroll for Colombian fighters with assistance from US companies connected to Duque. Monica Muñoz Ucros, Maine Global’s alternate manager, also manages Comercializadora San Bendito, which OFAC says moved money between entities in the network.
All eight individuals and companies have been sanctioned under Executive Order 14098, which targets actors undermining peace and security in Sudan.
Under the sanctions, all property belonging to designated individuals and organizations in the United States is frozen, and US persons are barred from conducting transactions with them. OFAC warned that violations may result in civil or criminal penalties. The Treasury said the investigation was conducted jointly with US Customs and Border Protection’s National Targeting Center.
