Moscow threatened a "symmetrical response" to Ukrainian attacks on Russian energy facilities, the Russian Foreign Ministry said on Saturday.
This comes just a week after the United States negotiated a short-term partial ceasefire between Russia and Ukraine.
Russia and Ukraine accused each other on Friday of blowing up a Russian gas pumping station in a border area where Ukrainian troops have been retreating. Unverified videos shared on Telegram showed a large fire at the station.
Russia has repeatedly attacked Ukrainian energy infrastructure in three years of fighting, and Ukraine has struck energy facilities in Russia.
"As in 2022, provocations are being used again with the aim of disrupting the negotiation process. We are clearly warning that if the Kyiv regime continues its destructive line, the Russian Federation reserves the right to respond, including with a symmetrical response," the ministry said.
'Kyiv unwilling to make peace'
The Ministry's statement noted that in spite of the agreement negotiated by the US that prevented either side from striking energy infrastructure, "the treacherous attacks by the Nazi regime on Russian territory continue."
"It is evident that through such actions, Kyiv once again demonstrates its complete lack of negotiability and its unwillingness to achieve peace," Spokeswoman for the Russian Foreign Ministry Maria Zakharova said in the Saturday statement.
The alleged attack on the gas pumping station came after a Russian strike killed 12 and injured six in the heavily contested eastern region of Zaporizhzhia early Saturday morning, the Kyiv Independent reported.
The region is home to one of the largest nuclear power plants in Europe, which has been under Russian control since 2022.
The New York Times reported that both sides had also blamed each other for separate attack on energy infrastructure this week.
On Friday, the two countries blamed each other for the attack on the energy station. The New York Times reported that Russia's Investigative Committee claimed that the Ukrainian military “carried out a deliberate explosion of the Sudzha gas distribution station,” and caused "significant damage.”
The Ukrainian Army said in a Facebook post that the "groundless" accusations were designed to "mislead the international community," against Ukraine.
The Facebook post claimed that Russian forces had previously hit the station as it attacked troops in the area.
Russia also struck a Ukrainian hospital on Tuesday, the night the ceasefire was effectively agreed upon.
Ukrainian president Volodymyr Zelensky said that the attack meant Putin "effectively rejected the proposal for a full ceasefire."
