ISTANBUL — All flights were briefly suspended at Istanbul's Ataturk Airport, Turkey's main hub, due to a snowstorm, a Turkish State Airports Authority (DHMI) official told Reuters on Wednesday. Turkish Airlines, Europe's fourth-biggest carrier, canceled 200 flights scheduled for Wednesday and Thursday due to adverse weather conditions, it said on its website. Discount carrier Pegasus also called off some flights at its hub on the Asian side of Istanbul. But later the authorities cleared some flights after the storm ebbed a little. — Reuters
