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.

BRATISLAVA (Reuters) - 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.

Slovakia’s Prime Minister Robert Fico said he wasn’t ruling out the resumption of gas through Ukraine after a deal between Kyiv and Moscow expired at the beginning of this year.

Slovak Prime Minister Robert Fico will discuss the end of Russian gas transit through Ukraine with representatives of the European Commission on Jan. 9 in Brussels, Slovakia's government office said on Tuesday.

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,

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.

Fico said that Slovakia could halt its humanitarian aid to Ukraine, cut or cancel social benefits for Ukrainian refugees, and cease emergency electricity supplies to Ukraine. He also suggested using veto power over EU decisions as leverage against Kyiv.
