Turkey Blockades Russian Shipping, Black Sea Fleet Completely Cut off
Turkey has begun a defacto blockade of Russian naval vessels, preventing transit through the Dardanelles and the Strait of Bosporus, between the Black Sea and Mediterranean.
According to the AIS tracking system for the movement of maritime vessels, only Turkish vessels are moving along the Bosphorus, and in the Dardanelles there is no movement of any shipping at all.
At the same time, both from the Black Sea, and from the Mediterranean Sea, there is a small cluster of ships under the Russian flag, just sitting and waiting.
The image below shows the situation with the ships using the GPS transponder on board each vessel:
In addition, shipping inside the Black Sea from Novorossiisk and Sevastopol in the direction of the Bosphorus, no Russian vessels are moving. This indirectly confirms the a CNN statement that Turkey may have blocked the movement of Russian ships on the Dardanelles and the Strait of Bosporus.
There is a Treaty specifically covering the use of these waterways by nations of the world. That Treaty is the Montreux Convention Regarding the Regime of the Straits.
