Ukraine President Volodymyr Zelensky has said Russia has enough missiles to carry out yet more heavy strikes against Ukraine following a wave of Russian attacks.
Engineers are continuing work to restore electricity after Friday's massive strikes using 76 missiles, reports BBC.
The attacks have targeted civilian infrastructure, as temperatures drop below zero in many regions.
Kyiv has accused Moscow of using winter as a weapon by targeting essential facilities as temperatures drop. But Russia's president earlier this month vowed to continue to batter Ukraine's infrastructure.
Russia's President Vladimir Putin has been consulting his military commanders about the future of the war.
The Kremlin says Putin spent the whole of Friday at the headquarters of Russia's military operation.
Putin said, "I would like to hear your suggestions on our immediate and medium-term actions."
Kyiv city officials said about 40 missiles had been fired at the capital alone - one of the biggest barrages since Russia's 24 February invasion.
The officials added that thirty-seven were brought down by air defences.
