Ukraine notifies Turkey of Russian submarine activity in Bosporus - Ukrinform

Ukraine has informed Turkey of recorded activity by Russian submarines in the Bosporus, which constitutes a violation of the Montreux Convention, Ukranian national news agency, Ukrinform reported. 

The Ukrainian military has provided relevant data on the activity to the Turkey through the Ukrainian Foreign Ministry, Leonid Zaliubovsky, a representative of the General Staff of the Ukrainian Armed Forces, told Ukrinform on Friday.

Zaliubovsky said the activity of Russian submarines violate the Montreux Convention and noted Ukrainian troops had recorded Russia's increased activity both in both the Mediterranean and Black seas.

"The Russian Federation, under the pretext of technical maintenance, actually organizes a full deployment of submarines in the Mediterranean. This is an obvious violation of international law," Zaliubovsky said.

The Ukranian General Staff also said Russia is looking to station another 14 warships in the Black Sea over the next three to four years. 

Russia’s annexation of Crimea in March 2014 made the Kerch Strait, which links the Azov to the Black Sea, a de facto internal waterway for Russia.
