Russia says eastern Ukrainian stronghold of Kostyantynivka ‘under our control’

The battle for this city, which had around 78,000 inhabitants before the war, has been taking place since late 2025 and now constitutes the main Russian effort on a front more than 1,000 kilometres long.

Kostyantynivka is one of the last Ukrainian strongholds on the way to the key cities of Kramatorsk and Sloviansk, whose capture is the Kremlin’s ultimate objective in the Donbas.

Peskov said Putin went to a Russian army command post, where he listened to a report from his general staff and thanked the Russian soldiers.

Russian forces now control the entire Luhansk region in eastern Ukraine, one of the two regions that make up the Donbass, Peskov added.

Chief of the General Staff, Valery Gerasimov, meanwhile said Russian forces were now nine kilometres from Zaporizhzhia, a major city in southern Ukraine that had more than 700,000 inhabitants before the war.

Another commander reported that his troops were 10 kilometres from the regional capital of Sumy in the north, which had around 250,000 inhabitants before the war.
