Ukrainian defense forces carried out overnight strikes against several key military and energy-related targets deep inside Russia, including the St. Petersburg oil terminal, facilities at the Kronstadt naval base, and a defense industry enterprise in the Tambov region, according to President Volodymyr Zelensky.
A large fire broke out in St. Petersburg early Wednesday after Russian officials reported a mass overnight drone attack on Leningrad Oblast, with Russian media and Telegram channels saying the Petersburg Oil Terminal had been hit.

Alexander Drozdenko, governor of Leningrad Oblast, said Russian air defenses had repelled an attack involving 30 drones. Earlier, he claimed that three drones had been intercepted over the region.
Despite official claims of interceptions, videos circulating on Russian Telegram channels showed flames and thick smoke rising from what they identified as the port area of St. Petersburg.
The independent Telegram channel Astra said it analyzed multiple eyewitness videos and concluded that the burning site was JSC Petersburg Oil Terminal, one of the largest oil handling facilities in northwestern Russia. Other Russian public channels also reported an attack on the facility.
Authorities also activated the “Kover” security plan at St. Petersburg’s Pulkovo Airport, according to Russian media, causing flight disruptions. More than 10 outgoing flights were reportedly delayed or canceled.

Local residents reported hearing a series of loud explosions before smoke and flames became visible in the city.
Drone strike reportedly hits Tambov defense plant
Hours before the explosions in St. Petersburg, Russian Telegram channels reported another suspected drone strike deep inside Russia’s Tambov Oblast, southeast of Moscow.
According to those reports, the Progress plant in Michurinsk was hit overnight and caught fire. The facility reportedly produces specialized control systems and equipment used in military aviation and missile technology.
Russian authorities have not confirmed the full scale of damage at the plant.
Zelensky confirms strikes on St. Petersburg oil terminal, Kronstadt base
In a statement published on Telegram, Zelensky praised the operation, which involved the Security Service of Ukraine (SBU), Unmanned Systems Forces (USF), Special Operations Forces (SSO), the State Border Guard Service, and other defense units.
“There are good results from our long-range sanctions. Important facilities on Russian territory were hit overnight,” Zelensky wrote.
The president specifically confirmed a strike on the St. Petersburg oil terminal, noting that the facility is located approximately 1,100 kilometers (684 miles) from Ukraine’s border.
“From our state border of Ukraine to this facility of the Russian oil industry, which is working for war, there are about 1,100 kilometers. Purely military targets at the Kronstadt base were also achieved,” Zelensky said.
According to him, another successful strike targeted an enterprise in Russia’s Tambov region involved in weapons production. The facility is located nearly 600 kilometers (373 miles) from the front line.
“I thank our soldiers for their accuracy. The Ukrainian long-range sanctions plan is being implemented exactly as it is needed to bring peace closer,” Zelensky added.
Putin’s “Davos” opens under smoke
The reported attack came on the opening day of the St. Petersburg International Economic Forum, often dubbed the “Russian Davos,” the Kremlin’s flagship annual business gathering, which Moscow uses to project economic resilience despite sanctions and growing international isolation over its war against Ukraine. The forum is scheduled for June 3-6, according to its official website.
Kyiv’s so-called “oil sanctions” campaign has routinely targeted Russian oil terminals, refineries and fuel depots – facilities that help sustain Moscow’s war machine.
