Russian troops control the village of Hrabovske in Sumy Oblast. The city of Siversk in Donetsk Oblast is also completely occupied.

Before striking a Kilo-class "Varshavyanka" submarine in the port of Novorossiysk, the Security Service of Ukraine (SBU) destroyed a Russian Il-38N maritime reconnaissance aircraft at the Yeysk airbase, which could have disrupted the attack.

To preserve soldiers’ lives and maintain unit combat effectiveness, Ukrainian defenders withdrew from the town of Siversk in the Donetsk region.

President Volodymyr Zelenskyy listened to reports from Rustem Umerov and Andrii Hnatov after meetings with the American team.

On the night of 23 December 2025, Russian troops launched a combined strike on critical infrastructure in Ukraine using strike UAVs, air-based and ground-based missiles.
