In Pictures: Four years of Ukraine war
Al Jazeera
UN says more than 15,000 civilians and 763 children have died, highlighting the immense human cost of the ongoing conflict.
Russia’s invasion of Ukraine four years ago initiated Europe’s largest conflict since World War II, causing profound civilian suffering, devastating military losses, and a fundamental shift in post-Cold War security dynamics.
The conflict entered its fifth year on Tuesday, with no resolution in sight.
Military casualties have reached staggering levels. A recent report by the Center for Strategic and International Studies (CSIS) estimates that Russia has had approximately 1.2 million casualties, including up to 325,000 soldier deaths between February 2022 and December 2025 – the highest number of military deaths for any major power in a single conflict since World War II.
Russia has not reported battlefield deaths since January 2023, when it confirmed losing more than 80 soldiers in a Ukrainian attack, bringing Moscow’s officially acknowledged military deaths to slightly above 6,000.
For Ukraine, CSIS estimates military casualties between 500,000 and 600,000, including up to 140,000 deaths. President Volodymyr Zelenskyy recently stated that 55,000 Ukrainian soldiers have died, with many more listed as missing. Neither side releases reliable or timely casualty figures, and independent verification remains unattainable.
