Ukrainian long-range drones struck oil infrastructure and naval facilities in St Petersburg and the Leningrad region on July 4, 2026. According to the Leningrad region Governor Alexander Drozdenko, air defenses intercepted 72 drones, while the Russian Defence Ministry reported 389 interceptions nationwide. The operation, which hit approximately 900km (560 miles) from Ukrainian-held territory, caused flight disruptions at Pulkovo Airport and forced local authorities to throttle mobile internet services to counter drone navigation systems.
How are drone strikes impacting Russia’s energy sector?
The campaign against Russian energy infrastructure has hampered the country’s refining capacity. Ukraine’s General Staff reported on July 4 that strikes have disabled 42.74 percent of Russia’s oil refining capacity as of early July, with over 60 storage tanks damaged or destroyed.
While Ukrainian military officials claim cumulative industry losses have reached $13.5bn since August 2025, independent energy analysts provide a more conservative estimate, placing functional disruption at approximately one-third of total capacity. The resulting fuel shortages have forced Moscow to implement export bans and restrict fuel sales across more than 40 regions and annexed Crimea. President Vladimir Putin acknowledged last Sunday that the attacks were causing a fuel shortage, though he described it as “not critical.”
Russian authorities used a unique defensive tactic during the July 4 strikes: they throttled municipal mobile internet networks. This was done specifically to jam the cellular-backed navigation systems used by the incoming Ukrainian drones.
What is the status of the conflict in central and eastern Ukraine?
While Ukraine targets Russian logistics, Moscow continues to strike Ukrainian energy and military sites. On July 4, the Ukrainian state energy firm Naftogaz reported that a drone strike hit a gas production facility in the Poltava region, resulting in a fire and a temporary suspension of operations. Naftogaz officials stated that the strike was part of a systematic effort to degrade Ukraine’s domestic gas output ahead of the upcoming heating season.
On the front lines, the situation remains contested. Moscow announced the capture of the strategic eastern town of Kostyantynivka, a claim President Volodymyr Zelenskyy explicitly dismissed as false. Ukrainian military command maintains that clashes are ongoing in the sector. This follows a high-casualty week for Ukraine, during which Russian attacks on Kyiv killed 30 people on Thursday, and glide bomb strikes on the city of Sumy killed at least four people on Friday.
How is the international community responding?
Diplomatic efforts to secure further support for Kyiv are accelerating. German Chancellor Friedrich Merz held a telephone conversation with Zelenskyy on July 4 to discuss the recent wave of Russian strikes. This dialogue serves as a precursor to the NATO summit in Ankara, Turkiye, scheduled for the following week.
Alliance members are expected to pledge €70 billion ($80bn) in military assistance to Ukraine for the year 2026. This funding is viewed as a critical component in maintaining Ukraine’s defensive capabilities as the conflict enters an increasingly industrial phase, characterized by long-range drone warfare and the targeting of national energy grids.
When tracking the economic impact of the war, look for shifts in official Russian export policy. Moscow’s decision to extend petrol export bans is a primary indicator of how effectively drone strikes are penetrating the domestic fuel market.
