One year ago, Russia invaded Ukraine. To date, about 100,000 Ukrainian troops and 8,000 civilians have been killed, while 200,000 Russian troops have been killed or wounded. Whole cities have been devastated. Ukrainian President Volodymyr Zelenskyy held a moment of silence in Kyiv as cities across the world displayed solidarity for Ukraine. In Berlin, candles were lit to form a giant peace sign and the Eiffel Tower glowed in the colors of Ukraine's flag.
