Russia claims capture of Kostiantynivka in eastern Ukraine; Kyiv silent on Moscow's victory announcement

Strategic significance of the city

Kostiantynivka, an industrial city with a pre-war population of 78,000, has been heavily contested since the end of 2025. Verbatim: Die Stadt, die vor dem Krieg 78.000 Einwohner zählte, war seit Ende 2025 schwer umkämpft. The front line between Russian and Ukrainian troops had been running roughly 20 kilometres south of the city in recent months.

The city is regarded as a strategically important staging point on the approach to the last major Ukrainian-controlled cities in the Donbas region. Kostiantynivka is one of the last Ukrainian bastions on the way to the strategically significant cities of Kramatorsk and Sloviansk, which Russia considers its top objective. Luhansk is one of the two regions that make up the Donbas.

Putin's announcement and evacuation order

In June, Putin announced that Russian troops were close to capturing the strategically important Ukrainian city. Putin described the capture of Kostiantynivka as being of 'great strategic significance' and was shown on television in uniform together with the Chief of the General Staff, thanking Russian soldiers.

Russian President Vladimir Putin ordered the immediate evacuation of all civilians remaining in Kostiantynivka on the evening of the announcement. The order underscored the extent of destruction already inflicted on the city and signalled that Russian authorities anticipate prolonged combat operations within its built-up areas.

Russian commander Anton Grunis stated that the army is conducting 'search and destroy operations against isolated Ukrainian soldiers trying to hide in buildings, basements and ruins.' Verbatim: die Armee unternehme "Such- und Vernichtungseinsätze gegen vereinzelte Soldaten der ukrainischen Streitkräfte, die versuchen, sich in Gebäuden, Kellern und Ruinen zu verstecken".

Kyiv's silence on the victory claim

The Kremlin claims Russian forces captured Kostiantynivka and that the city's Ukrainian defenders suffered heavy losses. Verbatim: Die Industriestadt sei unter hohen Verlusten für die ukrainischen Verteidiger erobert worden, wurde Putin von seinem Sprecher Dmitri Peskow zitiert. Der ukrainische Generalstab in Kiew sprach am Abend in seinem Lagebericht lediglich von schweren Kämpfen rund um Kostjantyniwka.

Von ukrainischer Seite gab es zu den Siegesmeldungen aus Moskau keinen Kommentar. The silence from Kyiv left Moscow's announcement uncorroborated and raised questions about whether fighting was still ongoing inside the city limits.

Zuletzt hatten ukrainische Militärs eine schwierige Lage in der bereits schwer zerstörten Stadt eingeräumt. That admission, made by Ukrainian military officials in recent days, suggested that the situation around Kostiantynivka had deteriorated sharply before the Russian claim of full control.

Strikes across Ukraine on the same day

The announcement came against a backdrop of intensified Russian strikes across Ukrainian territory. Nach den schweren Attacken auf Kiew am Vortag stieg dort die Zahl der Todesopfer. According to authorities, four people were killed in new Russian attacks on Ukraine on the day of the announcement.

In the eastern Ukrainian region, Olexander Ganscha, the military administrator of Dnipro, wrote that "Drei Tote und zwölf Verwundete, unter ihnen auch Kinder" had been reported in his region. The toll underlined the breadth of Russian drone and missile strikes hitting cities far from the front line.

Further south, Bei einer Drohnenattacke auf einen Markt in Tokmak, im von Russland kontrollierten Teil der ukrainischen Region Saporischschja, wurden etwa fünf Menschen getötet und 18 weitere verletzt, erklärte der örtliche Gouverneur im Onlinedienst Telegram. Die Region sei im Tagesverlauf von mindestens 50 Angriffen getroffen worden.

Beyond the Donbas, Russia reported continued Ukrainian drone strikes on occupied territory. "Der Feind greift das Stromnetz der Halbinsel täglich mit Drohnen an." Die Lage sei schwierig. "Derzeit sind mehr als zehn Bezirke ganz oder teilweise ohne Strom", wurde der von Moskau eingesetzte Gouverneur Sergej Aksjonow von der Agentur Tass zitiert.

Energy strikes on the Crimean peninsula

Russia has reported the capture of the eastern Ukrainian industrial city of Kostiantynivka in Donetsk Oblast, but the absence of Ukrainian confirmation leaves the operational picture uncertain. International observers are expected to scrutinise satellite imagery and frontline dispatches in the coming days to verify the extent of Russian control.

The wider context of the announcement is shaped by parallel strikes deep inside Ukrainian territory. Wie zwei mit dem Vorgang vertraute Personen sagten, traf die Drohne die Hauptraffinerieanlage, die 53 Prozent der Gesamtkapazität von Norsi ausmacht. The attack, attributed to drones, hit a major oil refinery in a third country and pointed to the expanding reach of the aerial campaign.

In the area around Zaporizhzhia, Weitere 21 seien verletzt worden, teilte der Militärgouverneur des gleichnamigen Gebiets, Iwan Fedorow, bei Telegram mit. The casualty figures from multiple regions indicated a wide-ranging Russian operation on the day Moscow announced its territorial gain.

Wider implications for the Donbas front

Nach jüngsten Angaben der Rettungsdienste wurden mindestens 30 Menschen getötet und mehr als 90 verletzt in the latest 24-hour reporting period across Ukraine, according to emergency services. The combined toll illustrated the human cost accompanying the Russian advance in the east.

Russian forces now control the entire Luhansk region in eastern Ukraine, according to Kremlin spokesman Dmitri Peskov. Verbatim: Die russischen Streitkräfte kontrollierten nun die gesamte Region Luhansk im Osten der Ukraine - eine der beiden Regionen, aus denen sich der Donbass zusammensetzt, erklärte Peskow.

If verified, the fall of Kostiantynivka would represent the loss of a key Ukrainian defensive position and would bring Russian artillery closer to the rear areas supporting Kramatorsk and Sloviansk. Diese Nachricht wurde am 03.07.2026 im Programm Deutschlandfunk gesendet, reflecting the broader European attention the claim has attracted.

Analysts caution that battlefield announcements from either side often outpace ground realities. Until independent verification is available, the status of Kostiantynivka is likely to remain contested in public reporting even as Russian troops continue operations within the city and its ruins.
