Ukrainian President Volodymyr Zelensky has provided updated figures on military casualties in the ongoing war with Russia, stating that approximately 50,000 Ukrainian service members have been killed and around 400,000 wounded. Zelensky also estimated that Russian forces have suffered about 1.6 million casualties, including 700,000 killed.
In a Fox News interview, Zelensky noted that many Ukrainian troops remain missing in action, expressing caution about revealing precise numbers to avoid giving Russia strategic insight. He acknowledged that the latest Ukrainian death toll is lower than a figure he provided in February, when he stated at least 55,000 Ukrainian soldiers had been confirmed killed.
The true scale of losses on both sides is difficult to ascertain, as neither Ukraine nor Russia regularly discloses complete figures. A recent study by the Center for Strategic and International Studies (CSIS) in Washington estimated Russia's battlefield casualties between February 2022 and June 2026 at 1.4 million, with up to 450,000 troops killed. The same study estimated Ukraine's losses to be between 525,000 and 625,000 casualties, including 125,000 to 150,000 killed. According to CSIS, combined military casualties from both sides have surpassed 2 million.
