Gas prices have soared after Russia further cut gas supplies to Germany and other central European countries after threatening to earlier this week.
European gas prices are up almost 2% trading above an earlier all-time high after Russia invaded Ukraine.
Critics accuse the Russian government of using gas as a political weapon.
Russia has been cutting flows through the Nord Stream 1 pipeline to Germany, with it now operating at less than a fifth of its normal capacity.
