Six explosions were also heard in the city's Pecherskyi district within three minutes of the air raid sounding, leaving no time to find shelter, a Kyiv Independent journalist on the ground said.

Five people have been reported killed in Ukraine, while Moscow's governor says the Russian capital was subject to "one of the most massive drone attacks of recent times".
