Ukraine Strikes St Petersburg Oil Terminal and Kronstadt; Russia Claims Capture of Kostiantynivka

Ukrainian drones struck an oil terminal in St Petersburg overnight on 4 July 2026, in what President Volodymyr Zelenskyy confirmed was a deliberate Ukrainian operation. St Petersburg Governor Alexander Beglov described the attack as 'large-scale' and reported no casualties. The strikes were part of a broader campaign targeting Russian energy infrastructure across multiple regions.

Zelenskyy characterized the attacks as 'long-range sanctions' targeting port oil infrastructure that generates revenue for Russia's war effort. Ukraine also claimed it struck Kronstadt, a major Russian Baltic Fleet naval base more than 850 km from Ukraine's border; Russia did not publicly confirm this claim. Additional strikes hit the port of Vysotsk, approximately 170 km northwest of St Petersburg on the Gulf of Finland, which handles oil, grain, coal, and liquefied natural gas.

Russian officials reported that 72 drones were shot down over the Leningrad region during the attack. The Russian Defence Ministry separately reported intercepting between 389 and more than 500 Ukrainian combat drones and missiles overnight and into the morning across Russia, though the exact figures varied by reporting window.

Ukraine has intensified long-range drone strikes on Russian energy infrastructure throughout 2026, causing significant damage to refineries and contributing to fuel shortages across Russia. Ukrainian officials stated their justification for targeting Russian oil and gas facilities is that Moscow relies heavily on fossil fuel exports to finance its invasion.

Center-left outlets reported that Ukraine claims nearly 43% of Russia's oil refining capacity has been disabled as a result of its drone strikes, though the BBC stated it could not independently verify this figure. The same outlets also reported that Putin made a rare admission that fuel shortages had been caused by Ukrainian attacks, and on Saturday signed a bill into law aimed at boosting domestic fuel supplies.

The BBC reported that the Ukrainian military described the St Petersburg oil terminal as one of the largest in Russia, capable of producing 12.5 million tonnes of petroleum products per year. Governor Beglov warned St Petersburg residents to stay indoors until the drone threat was over and cautioned that mobile internet services may have been disrupted.

The Guardian reported that drone strikes elsewhere in Russia killed one person in Bryansk region and one person in Crimea, with several more wounded in both areas. The governor of Pskov region reported more than 30 drones shot down overnight, with minor damage and injuries including at a factory in Velikiye Luki.

Deutsche Welle reported that Finland imposed temporary aviation and maritime restrictions in the eastern Gulf of Finland due to the Ukrainian drone attacks. The strikes on St Petersburg occurred weeks after Ukraine previously targeted the city on the opening day of an annual economic conference at which Putin was speaking.

The Guardian quoted Putin dismissing the strikes on Russian energy facilities as 'not critical.' However, the Russian Defence Ministry characterized the Ukrainian drone attacks as an attempt to distract attention from a major Russian strike on Kyiv on 2 July and from what it called a 'catastrophic failure' of Ukrainian forces in Kostiantynivka, warning that Ukrainian attacks on Russian civilian facilities 'will not go unanswered.'

Separately, Russia and Ukraine issued directly contradictory claims about control of Kostiantynivka, an eastern Ukrainian city in Donetsk. Russia's military told President Putin its forces had taken control of the city. Ukraine flatly denied this, with Zelenskyy and Ukraine's General Staff calling it 'another Russian lie' and insisting Ukrainian forces remain in control and are conducting active defensive operations.

Center and center-left outlets reported that Putin characterized Russia's claimed advance on Kostiantynivka as a 'strategic achievement,' calling the city a key transport and industrial centre of Donbas, while General Staff Chief Gerasimov described it as part of a wider effort to secure all of Donetsk.

The Guardian described Kostiantynivka as the southernmost of four key settlements forming a defensive line central to Ukraine's effort to hold the remaining part of the Donetsk region. The BBC reported that Zelenskyy challenged Putin to meet him in Kostiantynivka to find diplomatic solutions if the city is truly under Russian control.

The Guardian also reported that Russia's Defence Ministry claimed it had captured five villages in eastern Ukraine: Shyikivka, Novyi Myr, Cherneshchyna, and Druzhelyubivka in Kharkiv region, and Vasylivka in Donetsk region. Ukraine did not publicly comment on these claims.

The BBC contextualized the military actions as occurring ahead of a NATO summit scheduled for the following week in Turkey, with both sides seen as seeking to gain the upper hand. On Saturday, Putin sent US President Donald Trump a congratulatory note for 4 July celebrations, calling for 'constructive relations' between their countries.
