Editor's note

The humanitarian situation on the border between Greece and Turkey is growing more serious by the day. Since Turkey removed its border restrictions with Greece last week, thousands of people have made their way across the country to the Greek border. But Greece blocked their entry, and many are now stuck in no-man’s land in freezing conditions.

The crisis comes at a time of heightened tensions on the Greek islands, amid anger at plans to create closed camps for asylum seekers who arrive by sea. Ilay Romain Ors, who is in Greece researching the history of overlapping waves of migration in the Aegean, explains what’s been going on.
