The Black Sea has become the "most dangerous route" for commercial shipping, the Financial Times reports. Since the beginning of the year, more than 570 vessels have been attacked in the area, and at least 40 sailors have been killed. The Black Sea surpassed the Persian Gulf in the number of attacks. In the Gulf, 24 deaths of sailors were confirmed against the background of the conflict involving Israel, the United States and Iran. Over the past 45 days, Russia has been responsible for about 90% of the attacks on vessels in the Black Sea.
