Kyiv heating cuts and Baltic intercept, late December 2025

Summary
A look back at security reports from the final days of December 2025, from strikes on Kyiv to a Polish air force escort over the Baltic.
What did the security picture look like on 30 December 2025? The days leading up to that date brought a series of reports from across the region.
On 27 December, a Russian missile and drone strike hit Kyiv. Two people were killed and 32 were injured. Damage to critical infrastructure left 40% of residential areas in Kyiv and the surrounding districts without heating.
The same day, reports said Denis Kapustin, leader of the Ukraine-aligned Russian Volunteer Corps, had been killed in a Russian drone strike in Zaporizhzhia Oblast. It was later revealed that Kapustin had faked his death to thwart an assassination attempt.
Further north, on 25 December, the Polish Air Force intercepted and escorted a Russian aerial reconnaissance aircraft over international waters in the Baltic Sea. The aircraft stayed away from nearby Polish airspace.
Taken together, the reports from the days before 30 December 2025 covered strikes on civilian infrastructure in the Ukrainian capital, a reported death on the front line that was later shown to be staged, and a routine-style air intercept over the Baltic.
