Ukrainian drone strikes targeted key facilities in St. Petersburg on Sunday, igniting fires at an oil export terminal and an oil depot in Russian President Vladimir Putin’s hometown. The attack was part of one of the largest aerial offenses in the conflict, involving over 1,000 drones launched against multiple Russian regions, including the annexed Crimean Peninsula and areas near the Black Sea. Russian authorities reported intercepting and destroying a significant number of these drones.

The assault marked a significant escalation following the collapse of a fragile energy ceasefire that was announced just days earlier. Ukrainian President Volodymyr Zelensky said Russia had continued striking Ukraine’s energy infrastructure repeatedly since the ceasefire, causing widespread blackouts affecting tens of thousands of families. He accused Moscow of using these attacks to undermine Ukraine’s ability to maintain power and accused Russia of exploiting any easing of sanctions to prolong the war.

In addition to the oil facilities, drones also targeted a logistics center belonging to Russian retailer Ozon and a data center of the social network VK. While VK reported some service disruptions following the strike, the company stated services were mostly operational. Local officials said the drone attacks caused damage to residential buildings, injuring several people and killing at least one individual.

Russian officials maintained that Kyiv’s drone offensive could not alter the outcome of the conflict. Kremlin spokesperson Dmitry Peskov was quoted as saying Ukrainian forces were “resisting” the invasion but could not shift the strategic course of events. Meanwhile, Russian Defense Ministry reports detailed successful interceptions of Ukrainian drones, with more than a thousand destroyed over various regions.

The attacks have come amid rising tensions between Kyiv and Washington. U.S. President Donald Trump recently waived certain sanctions against Russia, a move that Zelensky criticized as supporting Moscow and undermining efforts to end the conflict. Trump defended his decision, citing the need to keep Russia at the negotiating table and avoiding actions that might derail peace talks. He also criticized Zelensky for continuing strikes on Russian energy infrastructure, suggesting the Ukrainian leader was reluctant to end the fighting.

Diplomatic efforts continue amid these military developments. Zelensky noted conversations with U.S. envoys regarding past negotiations in Miami and potential next steps. However, Ukraine’s Foreign Ministry apologized after one of its drones inadvertently entered Lithuanian airspace, prompting air raid alerts and local damage but no casualties. Officials suggested Russian electronic warfare may have diverted the drone.

The conflict persists on multiple fronts: Russia recently launched attacks on southern Ukrainian cities, including Zaporizhzhia, resulting in casualties, while Ukraine sustains its drone campaign inside Russia. The ongoing hostilities and diplomatic strain underscore the complexities of a conflict that continues to affect energy markets, regional security, and international relations.
