Ukrainian forces report intensifying Russian advances near Kostiantynivka in the Donetsk Oblast, raising concerns about a potential siege mirroring the recent fall of Pokrovsk. Russian troops are attempting to sever critical supply lines, potentially isolating the city and hindering Ukrainian defense capabilities. DeepState, a Ukrainian geo-location project, assesses that Kostiantynivka’s capture is increasingly likely, describing the situation as “a matter of time.” The offensive is occurring from multiple directions, increasing pressure on Ukrainian defenders. This development represents a significant escalation in fighting within the Donetsk region and threatens one of Ukraine’s remaining major strongholds. Military analysts suggest the loss of Kostiantynivka would further complicate Ukraine’s defensive posture in the east. The situation highlights the ongoing Russian strategy of attrition and encirclement.
