Ukraine marked its 100th day at war Friday as bitter fighting in the east continued and Russia's grip on captured territory remained tight. The toll of war on everyday Ukrainians has been brutal: At least 4,169 citizens have been killed, including 268 children, and at least 4,982 citizens have been injured, according to the latest count from the United Nations' human rights office, which says its tally is believed to be an undercount. Ukrainian President Volodymyr Zelenskyy on Thursday estimated Russia now controls about 20% of his country, an estimate which includes conquests during the current invasion as well as Russia's 2014 annexation of Crimea and partial command of disputed territory in Luhansk and Donetsk in the east. However, commenting on the 100 days mark, Zelenskyy was optimistic: “Our team is much larger," he said. "The Ukrainian Armed Forces are here. Most importantly, our people are here."
