Thirty-nine migrants dumped by Turkey on a border islet were rescued by the Greek police. They had been abandoned by Turkish smugglers on an islet in the river that runs along Greece's land border with Turkey.
A police statement said the 13 men, 11 women and 15 children had been ferried across in a plastic boat from the Turkish side of the Evros river.
It said all the migrants, who told police they were from Syria, were in good health. They were provided with food and clothing and taken to a reception facility in the northeastern town of Orestiada.
Police said the group phoned two nongovernmental organisations working with migrants to tell them they were on the island, about 80 metres (yards) from the Greek bank of the river.
The NGOs in turn notified Greek authorities and members of the European Union's Frontex border agency stationed in the area.
The Evros is a major crossing point for thousands of people from the Middle East, Asia and Africa seeking a better life in Europe, who mostly pay smugglers to ferry them to Greece.
Greek authorities are planning to extend a fence designed to stop illegal crossings that currently covers part of the Evros border.
