BOSPHORUS SHIPPING MOVES, ISTANBUL OFFICES CLOSE Istanbul remained at a virtual standstill today under snow up to a meter deep but shipping was moving through the narrow Bosphorus waterway linking the Sea of Marmara and the Black Sea, officials said. The authorities ordered government offices closed until Wednesday. Many banks, businesses and schools stayed shut as workers struggled to keep main roads and supply lines open in this city of 6.5 mln people. The second blizzard to hit Istanbul in a week stopped yesterday afternoon and the international airport reopened today after a two-day closure. It was also shut earlier last week.
