Slovakia's coalition government will discuss retaliatory measures to take against Ukraine after it halted the flow of Russian gas through its territory to Slovakia, Slovak Prime Minister Robert Fico said on Thursday.

Slovak Prime Minister Robert Fico described Ukraine's halt of the transit of gas supplied from Russia to the EU as "Zelensky's sabotage." In a video released on Thursday, he again threatened to cut off electricity supplies to Ukraine and discussed the possibility of reducing support for Ukrainian refugees in Slovakia.

Despite EU efforts to reduce dependence on Russian fossil fuels, Slovakia remains reliant on Russian gas under a long-term contract with Russia's state-owned energy giant Gazprom. Switching to alternative supply routes could cost Slovakia an additional €220 million ($229 million) in transit fees.

Ukrainian Energy Minister German Galushchenko also says Kyiv can buy electricity from Romania and Poland if it loses supplies from Bratislava.

Slovakia will consider reciprocal measures against Ukraine such as halting back-up electricity supplies after Jan. 1 if Kyiv, as expected, stops the transit of Russian gas to Slovakia, Prime Minister Robert Fico said on Friday.

Ukraine's Energy Minister Herman Halushchenko has expressed doubts about Slovak Prime Minister Robert Fico's threats to halt electricity supplies to Kyiv over Ukraine's stance on the transit of Russian gas.
