An overnight Russian air strike on the key Ukrainian grain exporting port of Izmail injured two people and damaged infrastructure, the governor of the Odesa region said on Tuesday.
A port building, storage facilities and more than 30 trucks and cars were damaged in the attack, which lasted more than two hours, Oleh Kiper said on the Telegram messaging app.
The Ukrainian military reported shooting down 26 of the 38 Iranian-made attack drones it said were launched by Russia.
Moscow has intensified its air attacks on Ukrainian ports on the Danube River, including Izmail and Reni, after it quit a grain deal in July that ensured the safe export of Ukrainian grains.
Separately on Tuesday, a Russian missile strike also damaged a local enterprise in the southern Ukrainian city of Kryvyi Rih, Mayor Oleksandr Vilkul said. There were no immediate reports of casualties.
Reuters could not independently verify the report. There was no immediate comment from Russia.
A Ukraine drone attack on Russia's Kursk resulted in power being cut off to about seven settlements in the region, the region's governor Roman Starovoyt said on Tuesday. He said there were no reports of injuries.
Earlier, Russia's defense ministry said its air defense systems had destroyed one Ukraine-launched drone over the Kursk at around 5:30 a.m. (0230 GMT). That followed reports of multiple drones being shot down over the region that borders Ukraine on Monday.
Reuters could not independently verify the reports. There was no immediate comment from Ukraine.
