Ukraine said on Monday that North Korean soldiers fighting alongside Russian troops suffered heavy losses during fighting at the weekend in the Russian region of Kursk.

Six people were killed and ten more were hospitalized in the Friday strike, Kursk acting Governor Alexander Khinshtein said.

Russia's losses in the war against Ukraine have already exceeded 779,000 soldiers. Over the last day, the Armed Forces of Ukraine eliminated 1,600 Russian occupants, according to the General Staff of the Armed Forces of Ukraine.

The presence of North Korean soldiers alongside Russian troops in the Russian region of Kursk has not yet had a major impact on the course of the fighting, a Ukrainian military intelligence official told AFP on Tuesday.
