Zelenskyy posted to Telegram on Monday following a briefing by Kyiv's top commander -- Gen. Oleksandr Syrskyi -- on the ongoing battle in Kursk, underway since Ukrainian troops launched a surprise cross-border incursion there in August.
"There are risks of sending additional soldiers and military equipment to the Russian army from North Korea," Zelenskyy said, vowing "tangible responses" to any such move. "According to preliminary data, the number of killed and wounded North Korean soldiers in the Kursk region already exceeds 3,000 people."
Ukrainian special forces claimed on Monday to have inflicted more than 100 casualties among North Korean forces over three days of operations.
