Russian troops are working deeper into Ukraine's last fortified cities in Donetsk Oblast, pushing infantry into Kostiantynivka while wrecking the towns behind it, the Ukrainian monitoring and analytical project DeepState reported. The US-based think tank Institute for the Study of War (ISW) recorded fresh Russian movement inside the city over the same days.
Kostiantynivka: Russian infantry keeps slipping in
Russian forces keep up constant infiltration attempts on Kostiantynivka, DeepState said. Their aim is to entrench inside the city, mass infantry there and take control of the ground. One of their main tasks is to take control of the part of the city between the settlements of Illinivka and Novodmytrivka. If Russian troops take Novodmytrivka, the entire Ukrainian grouping defending Chasiv Yar faces encirclement, DeepState noted. Supply into Chasiv Yar has been difficult for a long time, because Russian drone numbers hand Moscow the advantage in the air. Alongside the infantry, Russian forces use artillery and guided glide bombs to destroy the city.
ISW assessed on 28 July that Russian forces recently advanced in Kostiantynivka and kept up infiltration missions inside it. Geolocated footage from 27 July points to a Russian advance in the city's west, ISW said. Video published a day later shows Ukrainian troops hitting Russian positions in the north and center of Kostiantynivka, after what ISW assesses were infiltration missions.

Unnamed soldiers from units defending the city told Hromadske that the situation there is getting worse. Ukraine's General Staff counted 31 Russian attacks on the Kostiantynivka axis over the past day.

Druzhkivka and the towns behind the front are turning to ruins
The whole agglomeration around Kostiantynivka is suffering. DeepState said Druzhkivka and neighboring Oleksiievo-Druzhkivka are gradually turning into ruins under constant shelling, and staying there is extremely dangerous. Russian forces fired 1,243 times at the front line and residential areas of Donetsk Oblast on 28 July, Ukraine's National Police recorded.

Russian pressure is rising on the stretch running roughly from Yampil to Minkivka further north, which may become the next main axis after Kostiantynivka, DeepState said. Russian artillery is already destroying mine barriers along the routes it would use, and Russian drones are working against Ukrainian logistics there.
Sloviansk and Kramatorsk under fire 40 km deep
Russian forces are leveling Sloviansk and Kramatorsk—the northern anchors of the Fortress Belt—with guided glide bombs, rocket artillery, Shahed attack drones and small first-person-view drones that hunt people and cars in the streets. DeepState noted that Russian fire control runs about 40 km deep from the contact line. The agglomeration is gradually becoming an isolated place, where travel will soon be possible only out of critical necessity, in order to fight.

ISW noted that Ukrainian troops have recently advanced farther south, toward Huliaipole in Zaporizhzhia Oblast. A Russian milblogger acknowledged the Ukrainian gains near the town on 28 July.
