One day after Russia imposed a naval blockade on Ukraine, small cargo vessels continue approaching the war-torn country’s southernmost waters at the mouth of the Danube River.

As TradeWinds reported on Wednesday, the Russian defence ministry warned shipowners and flag states that as of 20 July it will consider any cargo vessel approaching Ukraine as a potential military target.

To drive the point home, its forces attacked early on Thursday the major ports of Odesa and Chernomorsk for the third night in a row.
