GREECE: Greek Islands Struggling With Migrants.

Europe is witnessing the biggest refugee crisis since the second World War. Yet, a solid solution still seems far away.

Nearly one quarter of a million migrants have crossed the Mediterranean to Europe this year, according to the International Organisation for Migration.

Of these, about half have come to the Greek islands including Kos.

There, the situation is desperate. It is hot, food and water are scarce, and many migrants are living in tents or in cardboard boxes on the street.

Syrian refugees are being processed for asylum - but that has led to scuffles among other migrants who say they are being left behind.

So what are the processing criteria? And who will decide?
