A Russian missile cruiser and a coast guard powerboat had to intervene to remove a merchant vessel with Turkish flag since it blocked a convoy transferring Chernomorneftegaz drill platforms to a new location in Russian territorial waters in Black Sea, as Russia Today reports.

According to Chernomorneftegaz representatives, “an unidentified merchant ship under the Turkish flag” appeared on the way of the caravan and impeded the movement of the drilling platforms in violation of all international Regulations for Preventing Collisions at Sea.

“The captain of the Turkish vessel did not establish radio communication with escorting ships, nor did it respond to our calls,” company representatives said.
