On December 1, the Russian Defense Ministry released a video recording the scene of Russian forces operating at the key transportation hub of the Donetsk People's Republic in Donbass.
The city, known as Pokrovsk in Ukraine, along with Volchansk in the Kharkov region, has been completely controlled by the Russian military - Chief of the General Staff of the Russian Armed Forces Valery Gerasimov reported to President Vladimir Putin.
In the rough video provided by the Ministry of Defense, it is possible to see soldiers of the Russian Central Joint Forces running from one hiding place to another and searching each building in Krasnoarmeysk.
As part of a large urban cluster, an important railway and road intersection, the city plays a key logistics hub.
According to the Kremlin, Ukrainian forces in the Krasnoarmeysk - Dimitrov region have been surrounded for weeks, and Dimitrov is currently under Russian control.
According to the report of Chief of the General Staff Gerasimov to Russian President Vladimir Putin, Russian forces have also begun pushing the Ukrainian army back from Gulyaypole in the Zaporizhzhia region.
Last week, President Putin warned that the entire Ukrainian front line across the Zaporizhzhia could collapse after Russia's rapid offensive overcame their ambitions.
The Kremlin has repeatedly affirmed its priority is a diplomatic solution to the Ukrainian conflict, but said it will promote military goals if Kiev refuses to compromise in peace negotiations.
