This is not the Russian army. It's the DPR militia. After 8 years of Kiev captivity, these towns are finally free. "The @wargonzo project, together with the advanced convoy of the DPR (Donetsk Peoples Republic), passed through 4 settlements previously controlled by the Armed Forces of Ukraine - Novoapostolovka, Chicherino, Svobodnoye and Donskoye.
In addition, the Donetsk group of troops overcame the second line of defense of the Armed Forces of Ukraine in front of Volnovakha, and also crossed the railway connecting Mariupol and Donetsk, coming close to the main highway."
