Russia says Europe gas flows on Jan. 3 in doubt

MOSCOW, Jan 2 (Reuters) - Ukraine has not given agreement to ship the full volume of gas to Europe on Saturday that Russia has requested, Russian gas export monopoly Gazprom (GAZP.MM) said on Friday.

"The Ukrainian side for the next 24 hours has not agreed to the needed transit volume," Gazprom spokesman Sergei Kupriyanov said at a Moscow news conference.

He said Gazprom expected to receive most of the arrears it is claiming from Ukraine by Jan. 11, though $614 million will still be outstanding.

Kupriyanov also said Ukraine had admitted stealing gas volumes intended for European customers, and said Gazprom was increasing supplies to Europe. (Reporting by Conor Humphries; Writing by Christian Lowe; Editing by Conor Sweeney)
