Ukraine reported a long-range strike in Siberia as Sofia and Kyiv investigate a drone blast near a Bulgarian gas pipeline amid continued Russian attacks in eastern regions.

Ukrainian forces targeted an oil refinery in Tobolsk, Siberia, in a long-range strike exceeding 2,500 kilometers, according to Ukrainian President Volodymyr Zelensky. The operation underscores Kyiv's expanding strike capabilities aimed at disrupting Russian energy infrastructure.

Concurrently, Bulgarian and Ukrainian authorities are investigating a drone explosion near a Bulgarian gas pipeline. Bulgarian defense officials stated the craft, which entered via Romania, resembled Ukrainian models and likely went off course. Kyiv denied intentionally targeting Bulgarian territory while confirming close cooperation with Sofia.

In eastern Ukraine, Russian bombardments killed at least three civilians and wounded nine others across multiple regions. Strikes on energy infrastructure cut power to roughly 99,000 customers in Chernihiv Oblast and accelerated depopulation in the frontline town of Druzhkivka, where fewer than 4,000 residents remain.
