Russia’s state-owned natural gas company Gazprom stopped supplies to Austria early Saturday, according to the Vienna-based utility OMV, after OMV said it would stop payments for the gas following an arbitration award.

The Russian energy company Gazprom abruptly halted deliveries of natural gas to Austria on Saturday following a legal dispute over supply interruptions. The stoppage was confirmed to dpa by Austrian energy company OMV spokeswoman Sylvia Shin.

Austrian energy company OMV said gas deliveries from Russia had ended at 6 a.m. (0500 GMT) on Saturday, but the regulator said supplies to customers were stable despite a drop in flows into Austria.
