Kyiv has finally turned off Russia’s gas supply to Europe, ending a source of income that helped pay for Moscow’s war against Ukraine. The decades-old deal, which allowed the transit of natural gas produced by Russian energy giant Gazprom through Ukraine, ended at midnight on December 31, shutting down Russia’s last major gas corridor to Europe.

Energy minister Herman Halushchenko confirmed on Wednesday that Kyiv had stopped the gas flows ‘in the interest of national security’.

Russia's gas transit to Europe via Ukraine has stopped, both countries have said, ending a decades-long arrangement and marking the latest casualty of the war between the neighbours.
