The Ukrainian port of Pivdenniy has halted operations because Russia is not allowing ships to enter it, in effect cutting it out of a deal allowing safe Black Sea grain exports, a Ukrainian official said on May 23. The Black Sea Grain Initiative signed by Russia and Ukraine in July 2022, and extended last week for two months, is intended to guarantee the safe wartime export of grains and foodstuffs from three Ukrainian ports -- Odesa, Chornomorsk, and Pivdenniy. The United Nations expressed concern on May 22 that Pivdenniy -- near Odesa on the Black Sea -- had not received any ships since May 2 under the deal.
