Ukraine struck one of Russia's largest oil refineries deep in the Urals and a military airfield overnight in a long-range attack, Ukrainian President Volodymyr Zelenskyy announced on 21 August. The Ukrainian Army's General Staff confirmed the refinery and airfield hits, while Zelenskyy said the same night also reached the Black Sea and brought fresh damage from earlier strikes on a Russian warplane and a drone-launch site.

Fire at a major Lukoil refinery in Perm

Zelenskyy said the overnight drones hit the Lukoil-Permnefteorgsintez refinery — known as PNOS — in Perm, where the General Staff recorded a fire on the plant's grounds. The target sits more than 1,500 km from Ukraine's northern border, in a region near the Ural Mountains.

The refinery is one of Russia's largest, able to process more than 13 million tons of crude a year, with more than half its output sold abroad until recently. It supplies fuel to both Russia's economy and its army.

Ukrainian Telegram channels Supernova+ and Exilenova+ shared footage of explosions and a rising plume, with locals reporting a series of blasts at the site. Russia's Perm Krai authorities claimed they repelled the attack and downed 16 drones.

Kyiv has repeatedly hit the plant through the year. After a strike at the end of July, it had been running well below capacity.

Airfield, Black Sea, and other targets the same night

The General Staff said the same night's drones also struck the Marinovka military airfield in Volgograd Oblast, located in Russia's Volga region, with the damage still being assessed, while Zelenskyy added that Ukraine achieved unspecified results in the Black Sea. The military also reported hitting a drone storage and launch site near Donetsk, a materiel warehouse in occupied Crimea, two command posts in Donetsk and Zaporizhzhia oblasts, and six relay stations in Crimea used to steer Russia's Geran and Gerbera attack drones.

Zelenskyy also confirmed damage from earlier strikes: a Russian Su-34 fighter-bomber hit at the Akhtubinsk airfield, about 600 km from the front line, and a drone store and launch site struck at Primorsko-Akhtarsk, roughly 180 km away. The strike extends a run of deep hits this month, from the TANECO refinery in Tatarstan and a Black Sea oil terminal to three refineries hit in one night and an Omsk refinery struck 2,500 km away in Siberia.
