Russia and Ukraine traded blame over an attack on a gas metering station in Russia’s Kursk region, near their shared border.
The strike on the Sudzha facility comes days after the US proposed both sides pause strikes on energy infrastructure.
Russia claims Kyiv “deliberately attacked” the station, which has been under Ukrainian control since its surprise incursion into Kursk in August 2024.
Moscow says Ukrainian forces blew up the facility while “retreating from the Kursk region” to discredit Trump's peace efforts.
Kyiv dismissed the accusations as “groundless,” calling them an attempt to mislead the international community.
The Ukrainian military claims Russia struck the same station with missiles just three days earlier.
The Sudzha station was the last route for Russian gas to Europe via Ukraine, but deliveries stopped on January 1 after Kyiv refused to renew the contract.
