Gunfire and clashes have erupted in the Sudanese capital of Khartoum between the army and the paramilitary Rapid Support Forces (RSF). The RSF stated they have taken control of the presidential palace, Khartoum International airport and Merowe airport, whereas the army denied the claims and said the fighting started after RSF troops tried to attack. Tensions between the military and the RSF emerged from a proposed transition to civilian rule that foundered over the timetable to integrate the RSF into the national army. The RSF wanted a delay of ten years, while the army stated it should occur within two years. After days of tensions, the situation looked like it would have been resolved when the army chief offered to speak to the RSF commander. However, that changed on Saturday with the sudden eruption of fighting. The United States' embassy is sheltering in place with its staff as they hear gunfire and fighting. The situation raises concerns of the first civil war in a decade, which would create significant geopolitical instability in the region.
