Greek ferries are tied up in port for a fourth day, stranding tens of thousands of residents of small islands, preventing agricultural produce from reaching mainland markets and trapping thousands of refugees on eastern Aegean islands. Pressure has mounted on the seamen's union to allow exceptions for ferries chartered to transport the refugees and other migrants who reach Greek islands from the nearby Turkish coast. Greece's coast guard says its crews are searching for the body of a 6-year-old boy and have recovered the body of another child after the boat they were on with another 14 people sank near the Greek island of Kos.
