"At the very moment of our conversation, the Russians attacked Ukraine yet again," Zelensky said, adding that "the Russians have only intensified their strikes, turning what should have been silence in the skies into an Easter escalation".
Zelensky had said earlier Kyiv was ready for a truce over the Easter holidays, but the Kremlin said it had not received any proposals.
Ukraine on Friday faced nearly 500 Russian missile and drone attacks that killed at least six people, officials said, the latest in an increasing number of daytime strikes by Moscow.
Images from Ukrainian emergency services showed damaged residential buildings, with a block of flats ripped and rubble strewn on a street.
The attack killed one person and left eight wounded in the capital region of Kyiv, regional governor Mykola Kalashnyk said.
Some residents of the capital sheltered in the metro or in basements, AFP reporters said, but many people sat in cafes unfazed by the barrage and despite blaring air raid sirens.
In the Kyiv region, "a drone struck a residential building in Obukhiv, and another attack occurred between a kindergarten and a school in Vyshneve, damaging homes," Prime Minister Yulia Svyrydenko said.
Three people were killed in Ukraine's northern Sumy region. One person was killed in the northwestern Zhytomyr region and another in northeastern Kharkiv, local officials said.
