A boy (L) cries out for help as a half-sunken catamaran carrying around 150 refugees, most of them Syrians, arrives after crossing part of the Aegean sea from Turkey on the Greek island of Lesbos, October 30, 2015. There were no casaulties amongst the refugees who were travelling on the catamaran, according to a Reuters witness. The death toll from drownings at sea has mounted recently as weather in the Aegean has taken a turn for the worse, turning wind-whipped sea corridors into deadly passages for thousands of refugees crossing from Turkey to Greece.
