The European refugee crisis is deepening with every day that passes. Hungarian authorities can barely cope with the large number of migrants entering their country's territory and they allow those holding valid papers embark on trains to take them straight to Munich or Berlin.

These days, trucks are queuing for dozens of miles at Austria's border checkpoints.
