Ukrainian drones attacked the Orsknefteorgsintez oil refinery in Russia's Orenburg Oblast on Oct. 3, a source in Ukraine's Security Service (SBU) told the Kyiv Independent.

The facility lies about 1,400 kilometers (870 miles) from Ukraine-controlled territory.

Founded in 1935, Orsknefteorgsintez is one of the oldest and largest refineries in the southern Urals, with an annual capacity of 6.6 million tons of crude oil.

Regional Governor Evgeny Solntsev confirmed the attack but claimed operations at the refinery were not disrupted. He said emergency services were working at the site.

The Kyiv Independent could not verify the claims.

According to the SBU source, an evacuation was announced at the facility.

"Nearly 40% of Russia's oil refining capacity is currently out of operation."

Sixteen of Russia's 38 oil refineries have been targeted since August 2025, according to the Financial Times.

The attacks have pushed Russian diesel exports to their lowest level since 2020.

Over the past week, Ukraine’s Armed Forces carried out new strikes on Russian oil refineries, forcing Russian authorities to extend a ban on gasoline exports and announce the introduction of a partial ban on diesel exports. Ukraine’s sustained campaign of strikes on refineries is now causing mild havoc at gas stations in Russia and occupied Crimea, with prices skyrocketing and short-term shortages widely reported.
