The U.N. says some 836,000 people have fled Ukraine in the week since the invasion started, in what “looks set to become Europe’s largest refugee crisis this century.” Poland says more than 450,000 people have crossed its border. This is a refugee from Kyiv who fled to Romania.

Ana Sohach: “In Ukraine, it’s like hell. We don’t know what to do. That’s why we cross into another country. So, we don’t know what would be tomorrow, so we are running. My husband is staying in Ukraine because there is no possibility to cross for man who is under 60 years, so of course he has stayed in Ukraine.”
