KIEV, September 11. /ITAR-TASS/. Ukraine’s Prime Minister Arseny Yatsenyuk has called on the European Union to start checks into Russia’s actions on cutting supplies of gas to the EU member states.

“These actions of the Russian Federation are an indicator of its unreliability as a gas supplier,” Yatsenyuk said at a meeting with Estonia’s president Toomas Hendrik Ilves, the press service of the Ukrainian government quoted him as saying on Thursday.

“It is a matter of national security for us,” Yatsenyuk said.

On Wednesday reports said that the Polish energy company PGNIG and the Slovak company SPP supposedly registered a decline in volumes of Russian gas supplies.

Itar-Tass reported on Thursday that the spokesman for the Russian major gas company Gazprom, Sergey Kupriyanov, said “the export of Russian gas to Poland goes on a schedule, in the volumes of a previous day,” and the “volume of gas delivered to the Slovak company SPP in September remains 12 million cubic meters a day every day.”

Meanwhile, the press service of the OMV energy company, the Austrian importer of Russian gas, told Itar-Tass on Thursday that Russian gas was delivered to Austria in routine amounts.

The situation with gas supplies to Austria was normal, a source said.
