BLIZZARD CLOSES BOSPHORUS Blizzard conditions halted shipping through the Bosphorus waterway and piled snow up to 70 cms deep in central Istanbul, paralysing the city for the second day running. Snow whipped by 48 kph winds continued to fall on Istanbul and northwest Anatolia after 36 hours and weather reports predicted no relief for another two days. Port officials said at least six large vessels in the Black Sea and 13 in the Sea of Marmara were waiting for conditions to improve. Istanbul's Ataturk international airport has been closed since yesterday.
