The first several hundred asylum seekers have been brought back from Greece to Turkey. At the same time, the U.N. High Commissioner for Refugees warns against the arrangement between the European Union and Turkey.

The worry is that the non-Syrians among the refugees will now be returned forcibly to wherever they came from, regardless of what fate awaits them there.

Amnesty International reports that Turkey is already forcing even Syrian refugees, including women and children, to return to their war-torn home country.
