Ukraine struck oil refineries in Russia's Krasnodar Krai and Yaroslavl Oblast, Zelensky says

Editor's note: This is a developing story and is being updated.

Ukraine struck oil refineries in Russia's Krasnodar Krai and Yaroslavl Oblast overnight on June 28, President Volodymyr Zelensky said, as Kyiv continued its campaign against Moscow's oil infrastructure.

"We will continue our operations that weaken Russia's ability to wage this war. Every long-range sanction reduces the resources fueling Russia's war machine and brings us one step closer to peace," Zelensky said.

According to the president, Ukrainian forces struck the Slavyansk oil refinery in Russia's Krasnodar Krai, around 300 kilometers (186 miles) from the front line, as well as an oil refinery in Yaroslavl Oblast, approximately 700 kilometers (435 miles) from Ukraine's border.

Russian authorities claimed one person was killed and another injured during the strike in Krasnodar Krai.

Photos and videos posted to social media purport to show large flames and plumes of smoke emanating from what appears to be storage tanks at the Slavyansk refinery.

The facility is considered a key fuel supplier for Russian-occupied Crimea, whose fuel reserves have effectively been paralyzed in recent weeks as Ukraine attempts to isolate the peninsula.

The Krasnodar Krai regional operational headquarters later reported that the fire at the oil refinery was caused by falling debris.

The extent of the damage caused was not immediately clear.

Elsewhere in Russia, smoke was seen rising from the area of the Yaroslavl oil refinery, located approximately 250 kilometers (150 miles) northeast of Moscow.

Yaroslavl Oblast Governor Mikhail Yevrayev said on Telegram that Ukrainian drones were targeting the region.

Ukraine's General Staff later confirmed that the overnight operation also targeted a railway bridge near Ichky in occupied Crimea, which Russian forces use to transport troops and military supplies, as well as an ammunition depot near the occupied town of Amvrosiivka in Donetsk Oblast.

The General Staff also said Ukrainian missiles struck three workshops at the Titan-Barrikady industrial complex in Volgograd, causing fires and partially damaging two of them.

Titan-Barrikady is a major Russian defense industry enterprise that manufactures missile launchers, artillery systems, and other military equipment.

The full extent of the damage to the oil refineries, railway bridge, ammunition depot, and defense facility is still being assessed.

Russia's Defense Ministry claimed its air defenses shot down 213 drones over 13 regions, annexed Crimea, and the waters of the Azov and Black seas. The Kyiv Independent cannot immediately verify the reports.

Amid the strikes, Russia has been facing a growing fuel shortage exacerbated by Ukrainian drone attacks on oil refineries. Over 20 Russian regions have imposed restrictions on fuel sales. Many Russians have taken to social media to report hours-long wait times to refuel at service stations.

The reported attack comes as Kyiv continues to escalate its campaign against Russian oil and gas infrastructure, a key source of Moscow's revenues helping to fuel its all-out invasion of Ukraine.

The latest strike comes days after Ukrainian drones struck two oil refineries in Russia's Republic of Bashkortostan on June 25.

A June 19 strike on the Moscow Oil Refinery halted operations at the facility — one of the largest in Russia, responsible for 40% of the Moscow fuel market and the majority of the region's gasoline. Days later, the Lukoil-Nizhegorodorgsintez refinery in Kstovo, Nizhny Novgorod Oblast, Russia's fourth-largest refinery, ceased operations following a Ukrainian drone strike, Reuters reported.
