KYIV - Ukrainian forces shot down a Russian Su-25 fighter-bomber over the Donetsk region in eastern Ukraine on May 4, President Volodymyr Zelensky said.

"It is important to be very focused these days," he said in his nightly video address.

"A special commendation goes to the warriors of the 110th separate mechanised brigade for today taking down another Russian Su-25 in the Donetsk region."

Mr Zelensky provided no further details of the incident, which Reuters could not immediately verify.

Donetsk is one of the four regions of Ukraine that Moscow claims to have annexed. Russian Defence Minister Sergei Shoigu said on May 3 that Moscow had taken control of 547 sq km of these territories in 2024. REUTERS
