Russian gas giant Gazprom has accused Ukraine of the unauthorized siphoning of Russian natural gas, the Echo of Moscow radio station has reported.
Gazprom said that part of the fuel intended for transit remained in Ukraine.
"For three days the total volume of the taken gas reached over nine million cubic meters," reads the statement.
To recall, on June 16, Russia cut off gas supplies to Ukraine, raising fears in Europe that there could be a disruption in supplies of Russian gas to EU countries.
June 19, German Chancellor Angela Merkel and French President Francois Hollande urged Russian President Vladimir Putin to resume negotiations with Ukraine on gas supplies.
