There was little sign of preparation on either side of the Aegean less than 24 hours before Greece was due to begin returning migrants to Turkey, and Greek and Turkish officials gave conflicting information on the logistics of the plan.
The returns are a key part of an agreement between the European Union and Turkey aimed at ending the uncontrollable influx into Europe of refugees and migrants fleeing war and misery in the Middle East, Asia and Africa.
Under the deal, those who cross into Greece illegally will be held and sent back once their asylum applications are processed. For every Syrian returned, one Syrian will be resettled to Europe directly from Turkey.
So far, more than 6,000 migrants and refugees have been registered on Greek islands since March 20, the date on which the agreement came into force.
Where they will depart from, to where they will be sent, and even how many people will be taken back to Turkey under this deal on Monday, remains unclear.
