KYIV, Dec 22 – Naftogaz Ukrayiny filed a complaint with the European Commission over Russia's Gazprom's abuse of its dominant position in the European gas market by submitting a petition to the Directorate General for Competition to take immediate measures to normalize the situation.

Gazprom has sharply reduced the sale of its own gas in the European spot market, despite growing demand, and limits the ability of other companies to supply additional volumes of gas to Europe and compete with Gazprom, Naftogaz Ukrayiny CEO Yuriy Vitrenko said.
