Twenty-six migrants were feared missing early on Sunday after a dinghy carrying them sank off the Greek island of Lesbos, the coastguard said, according to Reuters. Their nationalities were not immediately known. A search and rescue operation was under way and 20 other people were pulled from the water, a coastguard spokeswoman said. 'They (the migrants) told rescuers there were 46 people in the inflatable dinghy in total,' she said. Rescues and sinkings have become almost daily occurrences in the often choppy seas off Greece's eastern islands. Hundreds of thousands of mainly Syrian refugees have braved the short crossing from Turkey this year, mainly in flimsy and overcrowded inflatable boats.
