Russia's defence ministry said on Wednesday that Russian forces shot down four Ukrainian military jets in Ukraine.
Russian forces destroyed an Su-25 and Su-24 - both Soviet-era jets used by the Ukrainian air force - over the Donetsk region of eastern Ukraine along with another Su-25 and a Mig-29, another Soviet-designed fighter aircraft, in the Mykolaiv region of southern Ukraine, the defence ministry said in a daily briefing.
Reuters was not able to verify the reports.
