Thousands of protesters in the Slovak capital held banners and chanted slogans on Friday accusing Prime Minister Robert Fico of dragging the country towards Russia after he met President Vladimir Putin last month amid a gas dispute with Ukraine.

However, Fico says it will cost Slovakia 1 billion euros ($1 billion) a year in higher prices for the gas it uses and 500 million euros in onward transit fees. He has threatened to cut emergency electricity supplies to Ukraine as Russia attacks its power grid,

Russian President Vladimir Putin promised Slovakia that Russia's Gazprom would find alternative ways to deliver contracted gas to Slovakia after the end of transit through Ukraine, Slovak Prime Minister Robert Fico said on Friday.

Slovakian Prime Minister Robert Fico said Russia will if necessary deliver gas to cover the country’s domestic consumption this year, even as he seeks to restore fuel flows via Ukraine.

Thousands of people protested in cities across Slovakia on Friday evening against the Ukraine policy of Slovakian left-wing populist Prime Minister Robert Fico. The demonstrators accused Fico of following a pro-Russian course and of "betraying" Western allies and neighbouring Ukraine.

Protesters gathered in Bratislava and other Slovak cities on Friday to rally against the government's drive to seek closer ties with Russia despite its invasion of Ukraine.
