Russia is plundering gold in Sudan to boost Putin's war effort in Ukraine

Multiple interviews with high-level Sudanese and US officials and troves of documents reviewed by CNN paint a picture of an elaborate Russian scheme to plunder Sudan's riches in a bid to fortify Russia against increasingly robust Western sanctions and to buttress Moscow's war effort in Ukraine.

A heated debate transpired between officials in a back office of Khartoum International Airport. They feared that inspecting the plane would vex the country's increasingly pro-Russian military leadership. Multiple previous attempts to intercept suspicious Russian carriers had been stopped. Ultimately, however, the officials decided to board the plane.
