Ukrainian drones struck an oil depot in occupied Sevastopol, Crimea and the Novokuibyshevsk Oil Refinery in Russia's Samara Oblast in the pre-dawn hours of 18 April 2026, according to multiple Russian Telegram channels and monitoring accounts. A large fire was visible in the port area of Kazachya Bay in Sevastopol, while explosions were heard across the city and into the nearby settlement of Novofedorivka as Russian air defences activated throughout the night.
In Samara Oblast, a separate fire broke out at the Novokuibyshevsk refinery in the morning hours of 18 April following an apparent drone penetration of the facility's perimeter. The refinery, located roughly 950 kilometres east of Moscow, is one of Russia's mid-sized crude processing installations. Ukraine's military had not issued an official statement on the attacks as of midday 18 April, and the full extent of damage at both sites was not immediately confirmed.
The overnight strikes fit a pattern Ukraine has maintained since late 2025. Ukrainian forces struck 13 Russian oil and gas facilities between January and February 2026, according to Ukrainska Pravda reporting from 3 March 2026, and have continued hitting refinery and storage targets in the months since. Kyiv's strategic logic is straightforward: every barrel of refined capacity taken offline reduces the fuel revenues that underwrite Russia's military. Ukrainian officials have said publicly that attacking oil infrastructure is a legitimate means of shortening the war, even as the United States has at times pressed Kyiv to ease attacks that could affect global energy prices.
