Refugees, most of them Syrians, struggle to leave a half-sunken catamaran carrying around 150 refugees as it arrives on the Greek island of Lesbos, after crossing part of the Aegean sea from Turkey (Reuters) 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. The number of refugees arriving on Greek islands has leapt to 7,000 a day from about 4,500 at the end of September, probably because of fears the weather will worsen soon, the International Organization for Migration (IOM) said on October 9.
