Boeing 727 planes delivered weapons and drones through Chad, as well as foreign mercenaries to the Sudanese rebel movement Rapid Support Forces (RSF), said a draft report of the UN group of experts reviewed by Reuters. "The Panel received reliable information from four sources that the aircraft had transported RSF fighters and mercenaries, as well as equipment, including drones and weapons," the document says. According to the experts, three Boeing 727s arrived in Chad in November 2024 and were based at the military part of N'Djamena Airport. The UN experts also found reliable the estimate that from 1,500 to 2,000 Colombian mercenaries fought on the side of the RSF. According to the report, the mercenaries were hired by Global Security Services Group, a company registered in the UAE.
