Shipbroker Gibson this week highlighted the dangers to the tanker market of growing political tension between Turkey and Greece.

Last weekend, Turkish armed forces began military exercises on the disputed north of Cyprus under the banner “Mediterranean Storm”.

There were similar, but rival, exercises by Turkey and Greece near the Greek island of Crete last month.

Meanwhile, there are still major international tensions off Turkey’s Black Sea coast, where more vessels have been removed from their flag registers after calling at Crimean ports annexed by Russia in a dispute with Ukraine.
