- Lead. Ukrainian long-range drones flew more than 1,100 kilometres to strike the St. Petersburg Oil Terminal on June 3, setting it ablaze and sending black smoke billowing over Russia’s second city.
- Fact. The attack came as foreign delegates were arriving for Putin’s St. Petersburg International Economic Forum — Russia’s flagship annual investment summit — held just 17 kilometres from the burning terminal.
- Stake. The strike is a deliberate signal that Ukraine can reach deep-infrastructure targets inside Russia regardless of prestige diplomatic occasions, compounding the embarrassment of Putin’s scaled-back Victory Day parade weeks earlier.
Ukraine’s military struck the St. Petersburg Oil Terminal in Leningrad Oblast in the early hours of June 3, igniting fires at the facility, which has an annual throughput capacity of 12.5 million tonnes, according to reporting by the Kyiv Independent. Regional authorities said 50 drones were shot down over the region, but those that struck their mark were sufficient to send thick smoke across the city. Pulkovo Airport suspended flights briefly overnight; approximately 30 flights were delayed by more than two hours, and nine were diverted.
An attack timed for maximum visibility
The timing was not incidental. Putin’s St. Petersburg International Economic Forum — often described as Russia’s answer to Davos, drawing representatives from more than 130 countries — was opening its doors at the same moment the oil terminal burned on the city’s horizon. The forum is one of the Kremlin’s most carefully managed prestige events, designed to project economic normalcy and foreign investor interest despite two years of Western sanctions.
Ukraine’s strike followed a Russian mass-missile attack on June 2 that killed at least 23 people in Ukraine, according to Ukrainian authorities. Additional Ukrainian strikes on June 3 also hit the Kronstadt naval base and the Michurinsky Progress Plant in Tambov Oblast, a facility involved in weapons components manufacturing. President Volodymyr Zelenskyy confirmed that multiple Ukrainian military units were involved in the operation and said Kyiv’s long-range attacks target only “legitimate” military and energy infrastructure.
The strategic logic of deep strikes
Ukraine has systematically targeted Russian oil export and refining infrastructure as part of a campaign to erode the revenue Moscow uses to fund its war effort. The St. Petersburg terminal sits roughly 17 kilometres from the economic forum venue — close enough for forum delegates to see smoke on the skyline, far enough to avoid a direct diplomatic incident.
NATO Secretary General Mark Rutte commented that “as Ukraine continues to stand strong, to innovate and to make battlefield gains, Russia is increasingly desperate.” The Kremlin’s response was terse: spokesperson Dmitry Peskov said Russia’s answer would be “systematic,” and that Putin would address both economic and political topics in his forum speech. The St. Petersburg strike follows Ukraine’s earlier large-scale drone attack on Moscow, which demonstrated a widening reach that Russian air defences have struggled to fully counter.
