DeepState reports Russian advances near Kostiantynivka in Donetsk and inside Zaliznychne in Zaporizhzhya

What happened

The Ukrainian battlefield monitoring project DeepState reported on August 1 that Russian forces have advanced near Kostiantynivka in Donetsk Oblast and inside Zaliznychne in Zaporizhzhya Oblast. According to DeepState, 'the enemy advanced near Kostiantynivka and in Zaliznychne,' though the source does not specify which Russian units or broader operational context for these advances.

Outside Brief is treating this as a source-led account. Any disputed responsibility, casualty figure, battlefield claim or single-source assertion should be treated as unconfirmed/hearsay unless confirmed by another reliable source or a named official. Oleksandr Syrskyi, former Armed Forces Commander-in-Chief, stated that as of July 20, up to 145 Russian troops were operating inside Kostiantynivka. He also described the Kostiantynivka sector as one of the hottest areas along the front line. Ukrainian troops are reportedly conducting clearing operations, including counter-sabotage and search-and-strike missions, aimed at rooting out Russian infantry and firing positions.

Syrskyi added that Ukrainian forces have been using FPV drones and drone-dropped munitions extensively to locate and destroy Russian targets. Ukrainian strikes reportedly resulted in 21 Russian troops killed and 6 wounded on July 18, alongside the destruction of six Russian shelters. Additionally, Ukrainian troops cleared the central part of Kostiantynivka and raised the national flag over a city building on the same day.

What remains unclear

Despite these tactical developments, the reporting cautions that the information war remains active, and these front-line gains are part of a complex and evolving conflict dynamic. The ambiguous nature of the source—DeepState—and partial attribution of troop numbers and casualties to a former Ukrainian military officer suggest that some details may require further confirmation.

What remains unclear: Confirm whether the central claim is corroborated; until then treat it as unconfirmed/hearsay. Verification of Russian troop numbers operating inside Kostiantynivka and exact front-line control. Independent confirmation of the casualty figures for Russian troops in Kostiantynivka on July 18. Clarification of the locations and nature of advances reported by DeepState near Kostiantynivka and inside Zaliznychne.
