Russia does not want to confirm whether an agreement has been reached with Ukraine.
"The talks are continuing. When we have something to say on the matter, we will of course inform you," Kremlin spokesman Dmitry Peskov told AFP.
Ukrainian President Volodymyr Zelenskyy said at a security conference in Warsaw, the Polish capital, on Monday that Ukraine "will respond" if Russia does not comply with the "energy ceasefire".
"We are ready to respect an energy ceasefire if Russia is ready to do the same," Zelenskyy said.
He said he had heard about the ceasefire through the media, but that it must have escaped Russian President Vladimir Putin:
Putin apparently doesn't read Truth Social, referring to the social media platform that Trump often communicates via.
The head of the regional military administration in the Dnipropetrovsk region wrote on Telegram that Russia had targeted three districts in the region.
In the Zhytomyr region, the governor said railway and energy infrastructure had been shelled “repeatedly”.
No one was reportedly injured in those attacks, but at least 12 people were injured in Kharkiv on Monday morning, according to the city's mayor.
