Thousands of refugees and other migrants are heading to the Greek mainland from the eastern Aegean islands after the country's seamen's union called off rolling 48-hour ferry strikes.
The strike, which began Monday, had stranded an estimated 25,000 people on the islands.
Ferries began operating again Friday morning.
Several ships dedicated to refugees set sail from the islands of Lesbos and Chios, while others were taking ships from other islands on the regular passenger ferry service.
The ferries are heading to Greeces main port of Piraeus near Athens and the northern port cities of Thessaloniki and Kavala.
More than 600,000 people have reached Greece from Turkey so far this year. The vast majority don't want to stay, and head north through the Balkans to other, more prosperous European Union countries.
