“The total enemy casualties in this direction amounted to up to 245 military personnel as killed or injured, as well as two armored fighting vehicles," the ministry said in a statement, adding that Ukraine lost up to 70 soldiers in the South Donetsk direction.
Ukraine has also suffered up to 170 military casualties in the Krasny Liman direction and up to 160 in the Kupyansk direction, according to the ministry.
The Ukrainian counteroffensive began in June, with Kiev deploying brigades trained by NATO instructors and armed with Western equipment. Last month, Russian President Vladimir Putin said Kiev's push had failed, with Ukraine suffering casualties estimated at more than 90,000.
