The EU-Turkey deal, aiming to stop the flow of migrants into Europe via the Aegean Sea, came into effect on Sunday (20 March) but several outstanding legal issues and logistical challenges raise questions about how it would work in reality.
The deal under which the EU intends to return everyone, including Syrians, who arrives in Greece via smugglers, and resettle Syrian refugees directly from Turkey on a one-for-one basis, has not deterred migrants so far.
According to Greek authorities, 1,662 people had arrived on Greek islands by Monday morning, twice the official count from the day before, Reuters reported.
