The migrants, most of whom were from Syria and Afghanistan, travelled in three groups aboard rubber boats the 8 nautical miles (about 15 kilometres) from Turkey, it said. Several of the immigrants had to be rescued by helicopter from a steep section of the coast of the Aegean island. They were found late Friday and Saturday and all were well, it said.
