Slovakian Prime Minister Robert Fico called on Ukrainian President Volodymyr Zelensky to ensure the uninterrupted transit of Russian gas through Ukraine to Bratislava on Friday.
"If Zelensky does not allow our gas, a serious conflict may arise," Fico underscored.
The Ukrainian president previously stated that Kiev would not renew the transit agreement for Russian gas through its territory, which is set to expire at the end of the year.
