Russian forces struck six Ukrainian energy facilities hours after US President Donald Trump announced the two countries had agreed to an energy ceasefire, according to Ukrainian President Volodymyr Zelensky.
Trump stated on Sunday the truce would be "effective immediately." Zelensky said Russia responded by hitting "our gas stations, energy infrastructure, and other facilities." A Russian drone strike on a residential building in Kharkiv on Monday caused injuries. Zelensky told Fox News the strikes represented "Putin's answer to President Trump." He said 33 people had been injured in the strikes across the country.
Ukraine's state-owned grid operator Ukrenergo reported new power cuts in Kharkiv, Donetsk and Zaporizhzhia due to Russian attacks. Blackouts occurred in the city of Izyum after a Russian strike destroyed power grids, according to Ukraine's state news agency Ukrinform. Energy and railway infrastructure in western Ukraine were also targeted overnight. Electricity rationing was introduced in parts of Ukraine to avoid overloading damaged equipment.
Zelensky said on X the strikes were proof Russia was "unwilling to accept an energy ceasefire." When Trump first announced the ceasefire on Sunday, Zelensky said it was "news to him" that a truce was in effect. He backed the proposed ceasefire as a "major step toward ending the war, if the Americans truly step in now and make sure Russians respect the energy ceasefire."
Russia's Foreign Minister Sergei Lavrov said on Monday that Ukraine does not deserve the "respite" a ceasefire would bring. Moscow has said the installations it hits are legitimate targets because they support Ukraine's military operation. Zelensky has characterized Ukrainian attacks deep inside Russian territory as part of an effort to "reduce Russia's ability to finance the war."
For months, Ukraine and Russia have been exchanging strikes on energy infrastructure. BBC Verify analysis found both sides increased attacks in the lead-up to winter. In 2026, BBC Verify recorded 273 strikes on Russian-controlled oil and gas facilities, more than double the 124 recorded over the same period in 2025. Analysis by the Armed Conflict Location and Event Data project recorded 2.4 times as many reported Russian attacks affecting Ukraine's energy network so far this year compared to the previous year.
UK Prime Minister Andy Burnham said Britain "strongly supports President Trump's call today for a sustained energy ceasefire to start now." France, Canada and the EU also expressed support. However, EU foreign policy chief Kaja Kallas said the bloc would welcome an energy ceasefire "when it holds," noting the bloc had not yet seen Russia stick to it. Estonia's foreign minister said the ceasefire was "not working."
