The European Commission said Wednesday that Naftogaz Ukrainy hasn't notified it of any gas transit cuts to the European Union, the news agency RIA-Novosti reported.
It cited a Commission spokesman as saying that the E.U. learned about the cuts from media reports.
Russian gas monopoly OAO Gazprom (GAZP.RS) earlier Wednesday said that Ukraine is set to reduce gas supply to Europe within the next 24 hours to 325 million cubic meters from 386 mcm.
