Russia resumed its targeting of grain infrastructure in Ukraine’s southern Odesa region, local officials said on Wednesday, using drones in overnight strikes on storage facilities and ports along the Danube River that Kyiv has used for grain transport to Europe after Moscow broke off the export deal through the Black Sea.

At the same time, a loaded container ship stuck at the port of Odesa since Russia’s full-scale invasion more than 17 months ago set sail and was heading through the Black Sea to the Bosporus along a temporary corridor established by Ukraine for merchant shipping.
