MEDYKA, Poland (Reuters) - Ukrainians fleeing into central European pleaded for Western nations to take tougher steps against Russia following Moscow's invasion that has created more than 1 million refugees.

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