Ukrainian drones targeted Russia’s Tatarstan region, marking the first such attack since the invasion began, with one of the strikes hitting a refinery nearly 1,500 kilometers from the border. Ukraine has boosted its drone production to achieve ranges over 1,000 kilometers. Meanwhile, Naftogaz announced the completion of the heating season and the start of gas accumulation in storage facilities. Ukraine avoided gas imports in 2023 for the first time, thanks largely to reduced domestic consumption, and is offering its storage facilities to European customers for seasonal gas supply management.
