Ukraine Says It Struck Kronstadt Naval Base Area and Oil Depots in Western Russia

Ukraine’s military said it struck a cluster of Russian naval, fuel and logistics targets overnight, including the Kronstadt naval base area near St. Petersburg, while Russian regional authorities separately confirmed a major drone attack, air-defense activity and fires in parts of Leningrad region and Krasnodar Krai.

In statements released June 6, the General Staff of the Armed Forces of Ukraine said Ukrainian forces carried out strikes on Russian military and logistics targets on June 5 and overnight into June 6. Separately, officials in Russia’s Leningrad region reported air-defense activity and said drones were intercepted over the region, while Russian regional media and emergency-service reporting said a large fire broke out at an oil depot in Ust-Labinsk in Krasnodar Krai after a drone attack. Local reporting in Leningrad region also said firefighters were working near Bolshaya Izhora, and Ukrainian outlets cited photos and videos circulating online that appeared to show smoke or fire near Kronstadt and Lomonosov.

The Ukrainian General Staff said one of the main targets was the “Kronstadt” basing point in St. Petersburg’s island district of the same name, which Ukraine described as a key Russian naval base and support hub. Ukraine said explosions were recorded there, but that claim had not been independently verified.

Ukraine also said it struck multiple fuel and storage sites in Leningrad region: the Peterhofskaya oil depot in Lomonosov, a fuel terminal in Lomonosov historically associated with Neste, and an arsenal and storage complex of the 1060th Centre for Material-Technical Support near Bolshaya Izhora. The Ukrainian military said fires or secondary detonations were observed at some of those sites. Those specific damage claims remained unconfirmed by independent international observers at the time of reporting.

Farther south, the General Staff said Ukrainian forces hit an oil depot in Ust-Labinsk, a town in Krasnodar Krai. That was one of the clearest elements of the attack to be reflected in Russian reporting: regional media and emergency-service accounts said a large fire broke out at an oil depot there after a drone strike in roughly the same time window.

The Ukrainian military also reported additional strikes on command posts, drone-control sites, warehouses and troop concentration areas in Belgorod, Kursk, occupied parts of Luhansk, Donetsk and Zaporizhzhia, and in Kharkiv region. It did not provide independently verifiable public evidence for those claims in its initial statement, and Russian federal authorities had not issued a detailed public accounting of the reported damage.

A reported strike on Kronstadt would be significant because the port is the main basing, repair and logistics hub for Russia’s Baltic Fleet in the eastern Baltic and helps protect the sea approaches to St. Petersburg. The claims also fit a broader pattern of Ukrainian long-range strikes. Earlier in the same week, on June 2 and 3, Ukrainian authorities had already publicly claimed attacks on oil infrastructure near St. Petersburg and targets in Kronstadt.

Taken together, Ukrainian official statements, Russian regional reports of drone interceptions and fire response, and local media coverage point to a broad overnight attack reaching deep into western Russia. But the most detailed assessments of what was hit, and how badly, remained preliminary and came largely from Ukrainian military channels and OSINT-linked or Telegram-based monitoring, rather than from independent inspectors on the ground.
