Russian forces launched a significant assault on Odesa that caused multiple casualties and hit port facilities central to Ukraine's grain exports, prompting Ukrainian President Volodymyr Zelenskyy to accuse Moscow of threatening global food security. The attack adds to a broader campaign that Ukraine says has effectively shut its Black Sea shipping corridor, leaving more than 30 million tons of grain and oilseeds at risk as commercial traffic around Odesa, Chornomorsk and Yuzhny remains heavily disrupted. Last month, Ukraine's Infrastructure Ministry reported 35 attacks on ships in ports, 22 on ships at sea and 67 on port facilities, while war-risk premiums have climbed and Maersk has rerouted some cargo through Romania's Constanta. The strain has spread across the region, with attacks also affecting Russian export infrastructure and loading speeds at Novorossiysk and Tuapse. The renewed assault on Odesa drew international condemnation and sharpened attention on Black Sea military strategy after the collapse of the Black Sea Grain Initiative, which had moved about 33 million metric tons of grain. Market pricing cited in the report suggested a lower implied likelihood of Russian forces entering Sloviansk, and observers are watching for shifts in military focus, sanctions, military support and further changes in shipping and market signals.
