In Kyiv, an early morning strike on September 15 hit a warehouse and a petrol station, leaving one man in serious condition, according to Mayor Vitali Klitschko. Ukrainian authorities report that approximately 300 petrol stations have been targeted in recent months. Simultaneously, Russian regional officials confirmed damage to an Ozon warehouse in Taganrog and an industrial site in the Samara region. Governor Vyacheslav Fedorishchev stated that 40 drones were downed, though monitoring groups reported visible fires at the Syzran oil refinery.

The volatility spilled into NATO territory when a fighter jet intercepted a drone over Lithuania on September 15. The National Crisis Management Centre indicated the craft originated from Belarus. President Gitanas Nauseda praised the swift response, emphasizing the necessity of regional defense. This incident follows warnings from Ukrainian Foreign Minister Andriy Sybiha, who described recent Russian strikes near the Polish border as a direct provocation toward the alliance. While Trump asserted on Truth Social that both nations had agreed to cease energy strikes, President Volodymyr Zelenskyy maintained that any such cessation depends on verifiable guarantees from allies regarding the protection of Ukrainian infrastructure and food supply routes.
