The number of Ukrainian soldiers killed on the battlefield as a result of the country’s war with Russia is estimated to be 55,000, Ukrainian President Volodymyr Zelenskyy said, adding that a “large number” were also missing.

President Zelenskyy’s remarks on Wednesday came in the run-up to the fourth anniversary of Russia’s invasion of Ukraine and amid crucial ceasefire talks in Abu Dhabi, where negotiators are trying to end Europe’s largest conflict since World War II.

“In Ukraine, officially the number of soldiers killed on the battlefield – either professionals or those conscripted – is 55,000,” said Zelenskyy, in a prerecorded interview with France 2 TV.

Zelenskyy, whose comments were translated into French, added that on top of that casualty figure was a “large number of people” considered officially missing.

The Ukrainian leader did not give an exact figure for those who are still missing.

Zelenskyy had previously cited a figure for Ukrainian war dead in an interview with the United States television network NBC in February 2025, saying that more than 46,000 Ukrainian service members had been killed on the battlefield.

In the middle of 2025, the Center for Strategic and International Studies in Washington, DC, estimated that close to 400,000 Ukrainian troops have been killed or wounded since the war began.

Last month, the United Nations Human Rights Monitoring Mission in Ukraine reported that Russian attacks had killed 2,514 civilians and injured 12,142 in Ukraine in 2025, almost a third higher than the number of casualties in 2024.

Russia has also incurred heavy losses in the ongoing war.

In January, Ukraine’s military commander, Oleksandr Syrskii, was quoted as saying that in 2025 alone, almost 420,000 Russian soldiers were killed and wounded while fighting against Ukrainian forces.

An October 2025 estimate by British defence intelligence put the overall number of Russian soldiers killed or wounded in the war at 1.1 million.

Both Ukraine and Russia rarely disclose their own casualty figures in the war, though they actively report enemy losses on the battlefield.

Analysts say both Kyiv and Moscow are likely underreporting their own deaths while inflating those of the other side.

Kremlin spokesperson Dmitry Peskov said on Wednesday that Russia would keep fighting until Kyiv made the “decisions” that could bring the war to an end, while in Abu Dhabi, Ukrainian and Russian officials wrapped up a “productive” first day of new US-brokered talks, Kyiv’s lead negotiator Rustem Umerov said.

US President Donald Trump’s administration has been pushing both Kyiv and Moscow to find a compromise to end the fighting, although the two sides remain far apart on key points despite several rounds of talks.

The most sensitive issues are Moscow’s demands that Kyiv give up land it still controls and the fate of the Zaporizhzhia nuclear power plant, Europe’s largest, which now sits in a Russian-occupied area of Ukraine.

Moscow has demanded that Kyiv pull its troops out of all the Donbas region, including heavily fortified cities regarded as one of Ukraine’s strongest defences against Russian aggression, as a condition for any deal to end the fighting.

Ukraine said the conflict should be frozen along current front lines and rejects any unilateral pullback of its forces from territory it still controls.

Russian forces occupy about 20 percent of Ukraine’s territory, including Crimea and parts of the eastern Donbas region seized before the 2022 invasion. (Al Jazeera)
