Ukrainian forces say Russia's attacks on Sunday damaged an agriculture facility in the southern Odesa region.
The forces say they destroyed six drones and six of the 10 missiles launched by Russia before they hit their targets. But they say some missiles damaged agricultural warehouses in Odesa, which serve as the base for the country's agricultural exports.
Russia has been repeatedly attacking port and agricultural facilities in the region since July, when the country suspended the grain deal that had allowed exports of Ukrainian farm products through the Black Sea.
Russia's defense ministry said on Sunday that its forces shot down Ukrainian drones which had been heading for Moscow.
The ministry also claims Russian air defense systems destroyed six Ukrainian drones targeting Crimea, the southern peninsula Russia unilaterally annexed in 2014.
Ukraine has recently been saying that it damaged or destroyed the Russian Navy's vessels and air defense systems with missiles and maritime drones.
Ukraine's Vice Prime Minister Mykhailo Fedorov said on Friday that there will undoubtedly be more Ukrainian drones and attacks, and fewer Russian vessels in Crimea.
