Six Ukrainian energy facilities were struck by Russia in the hours following former US President Donald Trump's announcement of an energy ceasefire between the two nations, according to Ukrainian President Volodymyr Zelensky.

Trump stated on Sunday that the truce would be effective immediately, but Zelensky reported that Russia targeted "our gas stations, energy infrastructure, and other facilities." The strikes have led to blackouts in cities like Izyum, where power grids were reportedly destroyed, and have also affected energy and railway infrastructure in western Ukraine.

Zelensky indicated that 33 people were injured in the attacks on energy infrastructure nationwide. He suggested to Fox News that the Russian strikes were "Putin's answer to President Trump," implying a direct reaction to the former president's announcement.

The attacks come as global conflicts have influenced fuel prices ahead of upcoming US midterm elections. Trump had previously announced a plan on Friday to import Russian diesel into the United States. Ukraine's state-owned grid operator, Ukrenergo, confirmed new power cuts in Kharkiv, Donetsk, and Zaporizhzhia due to damage to energy equipment from Russian attacks, leading to electricity rationing in parts of the country.

On X, Zelensky stated the strikes demonstrated Russia's unwillingness to adhere to an energy ceasefire. In a separate incident on Monday evening, Kyiv's mayor reported a drone strike on a 25-story residential building in the Darnytskyi district, resulting in one death and 11 injuries, with several cars also catching fire.

When Trump first announced the ceasefire, Zelensky expressed surprise but backed the proposal as a significant step toward ending the war, contingent on American assurances that Russia would respect the energy truce. Responding to questions about the ceasefire on Monday, Trump asserted that Russia agreed "because I said you agree," and added that the conflict "has to get settled."

For months, both Ukraine and Russia have targeted each other's energy infrastructure, disrupting supplies. Russia has maintained that its targets are legitimate military support installations, while Ukraine has characterized its strikes within Russian territory as efforts to diminish Russia's war financing capabilities.

This latest development highlights the ongoing volatility in the conflict and the challenges in establishing and maintaining any form of de-escalation, particularly concerning critical energy infrastructure.
