A Russian security source told Reuters on Saturday that Wagner Group mercenary fighters had taken control of all military facilities in the city of Voronezh, around 500 km (310 miles)south of Moscow.

Wagner Group has trekked from Rostov, all the way to Voronezh, and taken control of the military facilities there.

For context, Voronezh is halfway between Rostov and Moscow, and this was accomplished in under a day.
