Dobropillya city, Donetsk oblast. The city has come under significant threat of operational encirclement. Russian infiltrators accumulate in two main points: at the coal mine east of Hannivka, and in Dobropillya township. They then launch deep assaults all the way through Svyatohorivka to the rear of Dobropillya along the Byk river. Infiltrators from Hannivka still pour through the northeastern and eastern parts of the city in large number; This part of the city could almost be considered grey. Due to the depth and repetition of these infiltrations, the grey zone now sits at a mere 1 kilometre from encirclement of most of Dobropillya city. Consolidation by the Russians is unlikely for now, but at this stage, the winter offensive toward Bilozerske seems to be in full swing.
