Key Russian oil pipeline node hit in massive Ukrainian drone barrage

Ukrainian forces hit the Saratov oil refinery, along with several other Russian oil industry facilities, overnight on May 31, the General Staff confirmed.

At about 3 a.m. local time, Saratov Oblast Governor Roman Busargin warned of a possible drone attack on the region and said air defense systems could be activated. Later, Busargin said that the strike had damaged a civilian infrastructure facility, but did not disclose the type or location.

No one was injured in the attack, according to Busargin.

The attack appeared to unfold in several waves overnight. Russia's Defense Ministry said air defenses intercepted 216 Ukrainian drones over 10 Russian regions, including Saratov Oblast, as well as over occupied Crimea and the Sea of Azov.

The operation was carried out by pilots of the 1st Separate Center of the Unmanned Systems Forces in coordination with Ukraine's Special Operations Forces, military intelligence, and other units of the Ukrainian Armed Forces.

The General Staff confirmed a large fire at the facility, saying the refinery is one of the key regional installations and part of Russian energy giant Rosneft.

The plant has a processing capacity of around 7 million tons of crude oil annually and produces gasoline, diesel, and other fuels used in part to support Russia's military logistics, the General Staff added.

Ukraine also struck the Lazarevo Linear Production and Dispatch Station in Russia's Kirov Oblast, which pumps crude oil through the Surgut–Gorky–Polotsk main pipeline, as well as a fuel and lubricants depot in the town of Matveyev Kurgan in Rostov Oblast, according to the statement.

Ukraine's Special Operations Forces said the Lazarevo Linear Production and Dispatch Station is located 1,200 kilometers (746 miles) from Ukraine's border and is linked to the Druzhba main pipeline system, enabling the Kremlin to rapidly transfer oil between two of the largest pipeline networks in the European part of Russia.

The Special Operations Forces clarified that long-range Ukrainian drones also struck the Agroproduct oil depot in Matveyev Kurgan, with large storage tanks, road and rail loading terminals, and a pumping station.

The extent of the damage remains under assessment, the General Staff said.

The Kyiv Independent could not immediately verify the reports.

Saratov is a key industrial site in the region, located around 150 kilometers (about 100 miles) from Kazakhstan's border and roughly 600 kilometers (370 miles) east of the Ukrainian front line.

The Saratov refinery has been struck several times since the start of Russia's full-scale war in Ukraine, most recently in March when a large-scale drone attack caused a temporary halt in the facility's production.

Ukraine has increasingly relied on domestically produced drones to strike targets deep inside Russia, particularly facilities tied to oil refining, logistics, and defense production.

According to data compiled by the Poland-based media outlet Vot Tak, Ukraine's military has struck Russian oil refineries at least 159 times since the start of Russia's full-scale war in Ukraine.

Most recently, Ukraine's Special Operations Forces (SOF) and the General Staff reported that Volgograd oil refinery was struck by Ukrainian drones overnight on May 29.
