A Russian attack on the Danube River port of Izmail in southern Ukraine destroyed 13,000 tonnes of grain, Ukrainian Deputy Prime Minister Oleksandr Kubrakov said on Wednesday.
Kubrakov said on the Telegram messaging app that the port's export capacity had been reduced by 15 percent by the overnight strike.
"In total, 270,000 tonnes of grain have been destroyed in a month of attacks on ports," he added.
There has been no response from Russia yet.
