Continued Black Sea strikes have effectively ended an informal understanding that neutral commercial vessels would not be targeted.

Ukraine's Unmanned Systems Forces attacked seven Russian shadow fleet vessels, two logistics facilities, seven substations and six air defence assets on the night of 19-20 July.

Three tankers and four dry cargo ships were hit in the Black and Azov seas as part of Operation "MoLoCHKa," according to Unmanned Systems Forces Commander Robert Brovdi.
