The direct attacks on Ukraine's grain, a key part of the global food chain, followed a vow by Kyiv to defy Russia's naval blockade on its grain export ports following Moscow's withdrawal this week from an UN-brokered safe sea corridor agreement.
"Unfortunately, the grain terminals of an agricultural enterprise in Odesa region were hit. The enemy destroyed 100 tons of peas and 20 tons of barley," regional governor Oleh Kiper said on the Telegram messaging app.
Photographs released by the emergencies ministry showed a fire burning among crumpled metal buildings that appeared to be storehouses, and a badly damaged fire-fighting vehicle. Two people were injured, he said, while officials reported seven people killed in Russian air strikes elsewhere in Ukraine.
Moscow has described the attacks as revenge for a Ukrainian strike on a Russian-built bridge to Crimea - the Ukrainian Black Sea peninsula seized by Moscow in 2014.
Russia has said it would deem all ships heading for Ukrainian waters to be potentially carrying weapons, in what Washington called a signal it might attack civilian shipping. Kyiv responded by issuing a similar warning about ships headed to Russia.
The attacks on grain export infrastructure and perceived threat to shipping drove up prices of benchmark Chicago wheat futures on Friday towards their biggest weekly gain since the February 2022 invasion, as traders worried about supply.
The UN Security Council was due to meet later over the "humanitarian consequences" of Russia's withdrawal from the safe corridor deal, which aid groups say is vital to fend off hunger in poor countries.
Turkish President Tayyip Erdogan, the deal's sponsor alongside the UN, said he hoped planned talks with Russian President Vladimir Putin could lead to the restoration of the initiative.
The end of the deal could lead to rising global food prices, scarcity in some regions and potentially new waves of migration, Erdogan told reporters on a flight back from a trip to Gulf countries and northern Cyprus.
The West should listen to some of Russia's demands, he said. "We are aware that President Putin also has certain expectations from Western countries, and it is crucial for these countries to take action in this regard."
Moscow says it will not participate in the year-old grain deal without better terms for its own food and fertilizer sales.
Western leaders have accused Russia of seeking to loosen sanctions imposed over its invasion of Ukraine, which already exempt exports of Russian food. Russian grain has moved freely through the Black Sea to market throughout the conflict and traders say Russia is pouring wheat onto the market.
