Two internal-conflicts have been raging in Sudan for years (in the region of Darfur and the states of South Kordofan and Blue Nile), while a civil war has been taking place in South Sudan since 2013. The head of the private Russian firm "RSB-group" said that he heard PMCs had already traveled to Sudan and had returned with a severe form of malaria. Several dozen PMCs from "RSB-group" were sent to Libya in early 2017, to an industrial facility near the city of Benghazi, in an area held by forces loyal to Field marshal Khalifa Haftar, to support demining operations. They left in February after completing their mission. The "RSB-group" was in Libya at the request of the "Libyan Cement Company" (LCC).
