The Kremlin said on Tuesday that contacts about an energy ceasefire between Russia and Ukraine, which US President Donald Trump announced on Sunday, were continuing but that it had nothing more to say on the matter for now.

Kremlin spokesperson Dmitry Peskov did not specify who Russia was ‌talking to about the ceasefire.

Trump's surprise announcement, which he said was "effective immediately," took Ukraine by surprise, according to President Volodymyr Zelenskyy, and Russia has not said whether it was informed about Trump's announcement beforehand.

Russia's ‌Defense Ministry said on Tuesday that its forces had not hit any Ukrainian energy-related targets in their overnight attacks.

Ukraine halted ​strikes on Russian oil ‌refineries and its other energy infrastructure ‌for two ‌days following Trump's ‌announcement of an energy ceasefire, Zelenskyy said on Tuesday.
