 Fighters from Yevgeny Prigazin's Private Wagner Militia drove in convoy past the Russian city of Voronezh on June 24. Still images showed personnel and equipment on the highway, with thick smoke from a fire at an oil depot billowing in the background. Fighters from Yevgeny Prigazin's Private Wagner Militia were in control of Rostov-on-Don, a city of more than a million people close to the border with Ukraine, and were rapidly advancing northwards through western Russia. The governor of Voronezh region Alexander Duzov said that more than 100 firefighters were working to put out a burning fuel tank at an oil depot. Earlier on Saturday, a Russian security source told Reuters that Wagner fighters had taken control of military facilities in the city of Voronezh, about 500 kilometers south of Moscow. Reuters could not independently confirm that assertion.
