 The Ukrainian Defense Ministry said on Thursday that it will consider all ships travelling to Russia and Russia-controlled areas in Ukraine through the Black Sea as potential carriers of military cargo. All vessels heading in the waters of the Black Sea in the direction of seaports of the Russian Federation and Ukrainian seaports located on the territory of Ukraine temporarily occupied by Russia may be considered by Ukraine as carrying military cargo with all the associated risks, the ministry said in a post on Telegram. The new rules will take effect from midnight local time on July 21, it said. The announcement came after Russia's Defense Ministry said Wednesday it would consider ships destined for Ukrainian ports via the Black Sea to be carriers of military cargo. Russian Foreign Ministry spokesperson Maria Zakharova said on Thursday that the Joint Coordination Center for Black Sea Grain Export in Istanbul, Turkey, has ceased operation, according to Sputnik News. On the same day, Ukrainian Foreign Minister Dmitry Koleba, who was paying a visit to Pakistan, called on the resumption of the agreement on the export of agricultural products at Black Sea ports.
