Zelenskyy said in a post on X that the assault caused significant damage to equipment at 26 facilities of Ukraine's power system and four facilities in the oil and gas sector. He highlighted a targeted ballistic missile strike against energy infrastructure, which he said should have been covered by the "energy ceasefire" Trump announced on Sunday as a way to help bring down oil and diesel prices.
"The strike was entirely deliberate and demonstrative in its scale: Russia has never before shown such ostentatious disrespect toward the United States," Zelenskyy said.
The attack follows accusations made Monday by the Ukrainian president that Russia was already violating the proposal to stop attacks on each other's energy facilities. Both Russian and Ukrainian authorities initially denied any knowledge of the agreement. Ukraine has since welcomed such a deal, while Russian authorities have described talks as ongoing and have not confirmed whether an agreement exists.
Russian Foreign Minister Sergey Lavrov said Monday, referring to the agreement's status: "We can refer to Zelensky's reaction. When asked the same question, he said he had not heard of such an agreement, would welcome clarification and was ready for a ceasefire," according to the Russian Ministry of Foreign Affairs.
