It comes after Moscow launched a massive drone and missile barrage at Kyiv earlier this week, killing at least 30 people and hitting more than 20 sites across the city.
Ukrainian forces carried out strikes on oil infrastructure sites near the Russian city of Saint Petersburg on Friday evening, Ukrainian President Volodymyr Zelenskyy announced.

In a post on X, Zelenskyy said Ukraine hit "port oil infrastructure that generates revenue for Russia's war".
"There were also successful strikes on Kronstadt – an important military target. The distance from Ukraine's state border is more than 850 kilometers," he added.
Alexander Drozdenko, the governor of Russia's Leningrad Oblast, had earlier reported that "several dozen" Ukrainian drones had been intercepted over the region, with debris falling on the port of Vysotsk.
Russian forces launched their own attacks on Ukraine's Poltava region on Saturday morning, targeting Naftogaz Group gas production facilities, according to Sergii Koretskyi, the company's CEO.
"A fire broke out at the site and operations at the facility have been suspended," Koretskyi wrote on Facebook. "It is not yet possible to assess the extent of the damage".

Kyiv's mayor described the strike as Moscow's "most massive attack" on the city.
Ukraine's air force said the attack included 570 air attack assets, including four Zircon missiles, 24 Iskander ballistic missiles, and 496 Shahed-type drones.
Kyiv has been repeatedly targeting Russia's energy industry in recent months as it looks to ramp up pressure on President Vladimir Putin and the Russian economy.
The attacks have sparked a fuel crisis across the country as well as in Russian-occupied areas, with limited petrol supply.
