European Commission head Ursula von der Leyen said in Davos on Tuesday that Russia was using food supplies as a weapon amid its war on Ukraine.
"In Russian-occupied Ukraine, the Kremlin's army is confiscating grain stocks and machinery," von der Leyen told global leaders gathered at the annual World Economic Forum in the Swiss Alpine resort.
She added that "Russian warships in the Black Sea are blockading Ukrainian ships full of wheat and sunflower seeds" to prevent Ukraine from exporting its grain to international markets.
Ukraine's inability to export its grain has raised the prospect of famines in countries that depend on these exports, the BBC reported.
