The Ukrainian military says Russia’s military losses have topped 1 million, noting the huge price Moscow has paid for its 3-year-old invasion.

Nearly 1 million Russian soldiers have been killed or injured in the country’s full-scale invasion of Ukraine, according to a new study, a grisly measure of the human cost of Russian President’s Vladimir Putin’s unprovoked three-year assault on its neighbor.

Russia will likely surpass 1 million casualties in its war on Ukraine this summer, according to one of the world’s leading think tanks.
