The War Zone – A Russian Shahed kamikaze drone strike on a ship in the port of Chornomorsk was in retaliation for a recent spate of Ukrainian attacks on Russian oil tankers in the Black Sea, the Ambrey maritime security firm tells us. The attack on the Turkish-owned CENK-T roll-on, roll-off cargo ship comes after Russian President Vladimir Putin warned he would “cut Ukraine off from the sea” in response to Ukraine’s stepped-up campaign against Russian commercial shipping.
