On June 23, 2023, the owner of the Wagner private military company, Yevgeny Prigozhin, declared a rebellion and moved his troops into the territory of the Russian Federation. The Russian President Vladimir Putin called these actions "a treason " and "a stab in the back ", while drawing analogies with the actions of the Bolsheviks in 1917. On the morning of June 24, the Wagner troops controlled key facilities in Rostov-on-Don and Voronezh. Fighting is already under way near Voronezh, there are casualties. A counter-terrorist operation regime has been declared in Moscow and a number of other regions of Russia. The situation is changing very quickly.
