Russia struck six Ukrainian energy facilities within hours of US President Donald Trump's announcement of an energy ceasefire between the two countries, Ukrainian President Volodymyr Zelensky said Monday.
Trump declared on Sunday the truce would be "effective immediately." Zelensky told Fox News that Russia had attacked "our gas stations, energy infrastructure, and other facilities" despite the announced ceasefire. He said 33 people were injured in the strikes across the country.
Ukrainian state news agency Ukrinform reported blackouts in the city of Izyum after Russian strikes destroyed power grids. Energy and railway infrastructure in western Ukraine was also targeted overnight. Ukraine's state-owned grid operator Ukrenergo reported "new power cuts" in Kharkiv, Donetsk and Zaporizhzhia due to damage from Russian attacks, and electricity rationing was introduced in parts of Ukraine to prevent overloading damaged equipment.
Kyiv's mayor Vitali Klitschko posted that a drone hit a 25-story residential building in the Darnytskyi district on Monday evening, with several cars in the building's courtyard catching fire.
Zelensky said on X that the strikes were proof Russia was "unwilling to accept an energy ceasefire" and told Fox News: "I think it was Putin's answer to President Trump."
Russia's Foreign Minister Sergei Lavrov said on Monday that Ukraine does not deserve the "respite" a ceasefire would bring.
The strikes follow months of tit-for-tat attacks on energy infrastructure by both sides. BBC Verify analysis found Russian attacks affecting Ukraine's energy network increased 2.4 times so far this year compared to the same period in 2025. Moscow characterizes energy installations as legitimate military targets supporting Ukrainian operations, while Zelensky has framed Ukrainian attacks on Russian territory as efforts to reduce Russia's war financing capacity.
International reaction was mixed. UK Prime Minister Andy Burnham, France, Canada and the EU expressed support for Trump's call. However, EU foreign policy chief Kaja Kallas said the bloc would welcome an energy ceasefire "when it holds," noting "we haven't yet seen that also Russia will stick to it." Estonia's foreign minister said the ceasefire was "not working."
Trump has urged Ukraine to halt strikes on Russian oil infrastructure to allow Russia to fulfill a recent deal releasing diesel to the US and global market. Zelensky described the deal, which temporarily removes US sanctions on Russian energy imports, as a "gift" to Russian President Vladimir Putin.
