Russia's gas giant Gazprom had warned it would cut off the supply at 04:00 GMT on Saturday.

Finland later confirmed all the deliveries had stopped, but said there would be no disruption to customers.

Helsinki has been refusing to pay for its supplies in roubles. But the cut-off also follows an announcement that Finland will apply for Nato membership.

Despite its invasion of Ukraine on 24 February, Russia continues to supply gas to many European countries.

After Western powers sanctioned Russia over the war, Russia said "unfriendly" countries must pay for gas using the Russian currency, a move the EU considers blackmail.

Reliance on Russian energy is a contributing factor in the cost-of-living crisis faced by many consumers.

Finland imports most of its gas from Russia but gas accounts for less than a tenth of the country's energy consumption.
