People carry a large Ukrainian flag marking a "day of unity" in Sievierodonetsk, the Luhansk region, eastern Ukraine, Wednesday, Feb. 16, 2022. The flags celebrated survival, endurance and above all, defiance. One blue and yellow banner curved along the edge of a stadium field. Others were tiny handheld things. One made it on the Olympic podium. Ukraine's president declared Wednesday a day of national unity in the face of “hybrid threats.” (AP Photo/Vadim Ghirda)
