Russia is suffering heavy losses from the continuation of “ferocious” attacks in the Donetsk region in eastern Ukraine and is preparing new attacks on Ukrainian energy infrastructure, Volodymyr Zelenskyi said on Sunday.

“Very fierce Russian attacks continue in the Donetsk region. The enemy is suffering serious losses there,” said the President of Ukraine in his evening speech.

Zelensky added that he believes that Russia is “concentrating forces and means for a possible repetition of massive attacks on our infrastructure, primarily energy.”

Over the past 24 hours, Ukraine has repelled 14 Russian attacks in the Kharkiv, Luhansk, Donetsk and Zaporizhzhia regions, the Ukrainian military reported.

Russia launched 4 missile and 19 air strikes on the territory of Ukraine and carried out more than 75 anti-aircraft missile strikes, the General Staff of the Armed Forces of Ukraine reports.
