In a statement published on Telegram, Zelensky said substations in the Vinnytsia, Zhytomyr, Khmelnytskyi and Odesa regions were attacked overnight into 18 October, leaving tens of thousands of households without power.
Russian forces also struck residential buildings, Zelensky said. Twelve people were injured, including two children, and two people were killed.
Over the past week, according to the Ukrainian president, the Russian army fired nearly 2,700 attack drones, 1,700 aerial bombs and 66 missiles at Ukraine, most of them ballistic. Zelensky named the energy sector as the main target of the strikes.
Zelensky said America must see that Russia is not meeting it halfway in response to the lifting of sanctions or the conclusion of agreements. "The war continues because of this position of Russia, and not because Ukraine is defending itself," he wrote.
Trump announced on 11 October that Russia and Ukraine had agreed to an energy ceasefire. Zelensky told journalists at the time that this was news to him, but that the Ukrainian Armed Forces had received the relevant orders.
On 15 October Zelensky warned that Ukraine would resume strikes on Russian oil refineries. He noted that even with Kyiv ready to observe the ceasefire, the Ukrainian army had lost access to the American satellite internet service Starlink.
Trump also announced an energy ceasefire between Russia and Ukraine in September. It was likewise not observed. He raised the ceasefire again after concluding a diesel deal with Russia.
