How the Ukrainian refugee crisis will change Europe

Editor’s note: This article was updated on March 30th after the UN High Commissioner for Refugees said the number of refugees leaving Ukraine had passed 4m.

LUTSK, IN WESTERN Ukraine, is not near the front lines, but it is within reach of Russia’s bombs. In mid-March they struck the town’s airfield for the second time. Yana Supruniuk, a 29-year-old interior designer, could see the fireballs from her flat. When she plays back the video on her mobile phone she still seems shocked to see it. At 5am on March 23rd, after days of indecision, she and a friend set off for the Polish border. Volunteers picked them up and drove them to Warsaw’s central train station. The pair queued for a ticket to Berlin, where a friend had agreed to put them up.
