More than 25 migrants or refugees were rescued and one child died today on a Greek island after the boat they sailed from the Turkish coast overnight either capsized or sank.<br/><br/>Greece's coast guard said a vessel from the European border agency Frontex initially picked up six people it spotted in the sea off the small southeastern island of Kastellorizo. The coast guard said one of the six, a 9-year-old girl, was taken to a hospital on the island but later died. <br/><br/>Greek authorities launched a search and rescue operation with patrol boats and a helicopter, and crews later found and rescued another 20 people who had managed to swim to a rocky coast on the island.<br/><br/>It was unclear what type of vessel the migrants had used and whether it sank or capsized. The coast guard said it appeared all those on board had been accounted for, but they were continuing the search and rescue operation as a precaution.<br/><br/>
