Ukrainian Forces Hit Strategic Yaroslavl Refinery and Russian Air Defense Systems

The Armed Forces of Ukraine (AFU) carried out a series of high-precision strikes between April 25 and the early hours of Sunday, April 26, targeting a major oil refinery deep inside Russia and critical air defense assets in occupied territories.

The General Staff reported a significant fire at the Yaroslavl refinery (Slavneft-YANOS) following a successful drone strike. The facility is a strategic asset for the Kremlin, processing approximately 15 million tons of oil annually.

Its production of gasoline, diesel, and jet fuel is vital for the Russian military’s logistics and its central industrial regions. Andriy Kovalenko, Head of the Center for Countering Disinformation, earlier released footage confirming the impact on the site.

Simultaneously, Ukrainian units struck Russian military trains in the Menchuhove and Kelerivka areas of the occupied Donetsk region. The General Staff also confirmed the destruction of high-end Russian equipment from previous operations on April 24, including a Kasta-2E1 radar station in Melitopol and a Pantsir-S1 surface-to-air missile system in Mariupol.

This campaign follows a week of systematic degradation of Russia’s military and economic infrastructure. On April 22, the Tuapse and Novokuibyshevsk refineries were forced to halt operations after coordinated strikes, with the Tuapse facility suffering what local observers called a “man-made disaster.”

Putin Signs Law Allowing Seizure of Property From Russians Abroad for ‘Offenses Against State Interests’

Kremlin leader Vladimir Putin approved legislation that will enable Russian courts to seize properties, bank accounts, and other assets of Russian citizens abroad if accused of a broad range of “administrative offenses” against Kremlin’s interests. The law, effective from Sept. 1, formalizes and expands existing practices of political repression, raising the stakes for exiled critics.

As Kyiv intensifies its long-range strikes – recently reaching as far as 1,800 km into the Ural Mountains – the focus on destroying air defense systems like the Pantsir-S1 and Kasta radar is seen by analysts as a prerequisite for further successful deep-strike operations against the aggressor’s industrial heartland.
