The US Treasury's Office of Foreign Assets Control (OFAC) targeted eight entities and individuals, primarily Colombian, accused of recruiting and training mercenaries for Sudan's paramilitary Rapid Support Forces (RSF) during the ongoing civil war that escalated in 2023-2024. Hundreds of Colombian fighters, including ex-soldiers and drone pilots, have been sent to Sudan, reportedly under deceptive hiring practices promising low-risk jobs. The RSF has been condemned for committing war crimes and genocide against civilians, further destabilizing the region. The network includes a dual Colombian-Italian former military officer based in the UAE, a country accused but denying supplying arms to the RSF. The RSF's recent territorial gains include Darfur's city of el-Fasher and Sudan's largest oil field, exacerbating humanitarian crises affecting millions with famine and displacement. US sanctions block all property and interests of the designated network within US jurisdiction to disrupt their operations. The situation remains volatile with significant civilian casualties and international concern over escalating violence and foreign mercenary involvement.
