Ukrainians fleeing into central European countries pleaded for Western nations to take tougher steps against Russia following Moscow¡¯s invasion that has created nearly 1.5 million refugees.

At the Medyka crossing, Poland¡¯s busiest, along its roughly 500 kilometer (310 mile) border with Ukraine, refugees called for a no-fly zone over Ukraine ¡ª something NATO powers have so far ruled out on the grounds that it would risk escalating the conflict beyond Ukraine.

¡°Please close the sky,¡± said Solomiya Zdryko, 18, who fled from Lviv in western Ukraine. ¡°I know that it¡¯s not possible for us to join NATO but at least close the sky because people are dying.¡±
