The number of tankers waiting to pass through Istanbul's Bosphorus Strait on the way to the Mediterranean fell to 13 on Monday from 17 a day earlier, the Tribeca shipping agency said, showing an easing of the recent build-up in traffic.
A Turkish measure in force since the start of the month has caused shipping delays. It requires vessels to provide proof of insurance covering the duration of their transit through the Bosphorus Strait or when calling at Turkish ports.
