Ukraine has resumed attacks on Russian energy infrastructure, saying Moscow failed to stop strikes on Ukrainian power facilities. A fire broke out at a major refinery in Russia’s Ryazan region on October 15, while Ukrainian President Volodymyr Zelenskiy said Kyiv would no longer observe a short-lived restriction covering energy targets. The development showed that an energy ceasefire initiative announced days earlier by US President Donald Trump had not taken hold on the battlefield.
According to Reuters and the Associated Press, the target was a refinery in the Ryazan region southeast of Moscow owned by Russian state oil company Rosneft. Ryazan Governor Pavel Malkov said a large Ukrainian drone attack caused a fire at the facility. The scale of the damage and its effect on production have not been independently established.
Why the brief restriction ended
Trump said on October 11 that Russia and Ukraine had agreed to stop attacks on energy sites. Moscow and Kyiv, however, did not subsequently publish a joint document defining the arrangement’s scope, duration or enforcement mechanism. Zelenskiy said Ukraine temporarily suspended strikes on Russian refineries but argued that Russian forces continued to attack Ukraine’s energy network.
In an interview with the Financial Times, Zelenskiy said that restriction was over. Reuters and AP reported that the Ukrainian leader linked the decision to continuing Russian missile and drone attacks on electricity generation and distribution infrastructure. The Kremlin said the scope of the proposed energy ceasefire had never been fully defined and argued that Ukrainian strikes on Russian energy facilities ran counter to US-led peace efforts.
Renewed tension between Washington and Kyiv
The Ryazan strike came amid renewed strain in relations between Kyiv and Washington. Zelenskiy alleged that restrictions affecting US intelligence sharing and military satellite communications had weakened Ukraine’s defensive capacity. The Trump administration denied deliberately withholding intelligence from Ukraine.
Ukrainian officials also said technical limits affecting the military Starlink service, known as Starshield, had disrupted some drone missions when terminals were mounted on fast-moving platforms. SpaceX chief executive Elon Musk said Starshield systems are owned by the US government and that their operating limits are determined by US authorities. The operational effect of the reported restrictions has not been independently verified.
Energy infrastructure remains central to the war
Ukraine views long-range drone strikes as a way to pressure Russia’s oil-processing capacity and military logistics. Moscow says such attacks threaten civilian energy security and fuel supplies in international markets. Russia, meanwhile, regularly targets Ukrainian power generation and transmission facilities; Kyiv said the latest strikes left hundreds of thousands of people without electricity.
The collapse of the energy pause underscores the fragility of broader diplomatic efforts to secure a ceasefire. Neither side announced a binding verification mechanism for energy targets, leaving the proposed arrangement vulnerable to conflicting claims and rapid escalation. The full effect of the Ryazan fire on refinery operations and the targets chosen by both sides in the coming days will help determine whether the confrontation widens further.
