Ukraine's state energy company says Russia's Gazprom has not delivered the full amount of gas Kyiv paid for in advance.
Naftohaz press secretary Alena Osmolovskaya said the Ukrainian company prepaid for some 114 million cubic meters of gas but received only 47 million cubic meters, RFE/RL reports.
Osmolovskaya said Gazprom's failure to deliver the full amount of gas represents a violation of the three-party agreement reached between Russian Energy Minister Aleksandr Novak, Ukrainian Energy Minister Yuriy Prodan, and European Energy Commissioner Guenther Oettinger in Brussels on October 30.
Nafothaz said that agreement is a legally binding protocol.
Naftohaz said it sent a note to Gazprom demanding an explanation for the shortage of gas shipments but there was no response from the energy company.
