Sunday is the day an agreement between the European Union and Turkey on ending illegal migration goes into effect but its implementation still remains uncertain.
Greek authorities say they’re not sure any migrants entering Greece will be processed and turned back before Monday.
Greece is expecting 2,300 European experts, including migration officers and translators, to help implement the deal. None have arrived yet.
Instead, 875 new refugees have arrived in four of Greece’s Aegean islands close to the Turkish coast. In one of the boats arriving on the island of Lesbos, two Syrian men were found dead of yet unknown causes.
Greece is still relocating migrants from the islands to temporary camps on the mainland. A ferry carrying 1,169 migrants arrived on Sunday at a port west of Athens.
