One person died and four people, including a seven-year-old girl, were taken to hospital following the early morning strikes, said city mayor Vitali Klitschko.

Russia denied it had hit a civilian target, however, saying its forces had struck the Artyom weapons factory in the neighbourhood.

Earlier, it announced strikes against three military centres in northern and western Ukraine, including one near the border with Poland.

The high-profile attacks come as a week of Western diplomacy kicked off with the G7 summit in Germany, which will be followed by a meeting of NATO leaders in Spain.

Allies including US President Joe Biden -- who condemned the Kyiv attack as "barbarism" -- will take stock of their support for Ukraine and for sanctions imposed on Moscow.

The G7 talks opened Sunday with the announcement of a ban on imports of Russian gold, but Ukrainian Foreign Minister Dmytro Kuleba called for more.

He posted on Twitter a photo of an injured child being carried on a stretcher, who he said was "sleeping peacefully in Kyiv until a Russian cruise missile blasted her home".

The "G7 summit must respond with more sanctions on Russia and more heavy arms for Ukraine. Russia's sick imperialism must be defeated", he said.

Ukrainian President Volodymyr Zelensky will address both the G7 and the NATO summit, the week after the EU showed its support by granting Kyiv candidate status.
