At least eight people have been killed in shelling overnight which hit houses and a shopping district in Kyiv's Podil district.
The Kyiv department of the Ukrainian state emergency service confirmed the casualties after the late attack on Sunday evening.
The city's mayor Vitali Klitschko said: "According to the information we have at the moment, several homes and one of the shopping centres [were hit]."
"Rescuers are extinguishing a large fire in one of the shopping centers in the Podolsk district of the capital. All services - rescue, medics, police - work on site. The information is being clarified."
Footage of the horrific moment where the strike hit the shopping centre has been published by a number of Ukrainian officials on social media.
The bombings continued across Ukraine overnight, with Mariupol again being heavily targeted.
Over 300,000 people have been trapped in the city after it became encircled by Russian troops last week.
Already, a maternity hospital and two children's hospitals were attacked, killing hundreds of people.
On Sunday evening, Russia demanded the city be surrendered, only for this to be roundly rejected by the Ukraine government.
Russian Colonel-General Mikhail Mizintsev told his counterparts they have until 5am Moscow time (2am GMT) on Monday to respond to his ultimatum, RIA claimed..
According to the state controlled media outlet, "the Ministry of Defence wanted to receive a written response from Kyiv" to demands to surrender by that time.
The city is currently encircled by Russian troops, with very little access to food, water and power as a result.
Russian Colonel-General Mizintsev urged Ukrainian forces in Mariupol: “Lay down your arms.
“A terrible humanitarian catastrophe has developed. All who lay down their arms are guaranteed safe passage out of Mariupol.”
But Ukraine has rejected Russian calls to surrender the port city.
