The Ukrainian capital came under a wave of attacks overnight, the first such strikes since 28 September.
A couple in their 60s were killed when a drone hit their high-rise building in the city, and four people were killed in the wider Kyiv region. Among the victims were a woman, a six-month-old baby and a girl aged 12.
The mayor of Kharkiv said later that a 40-year-old man was killed and five other people were hurt in a series of drone attacks. A private kindergarten was hit and children were among the wounded, said Mayor Ihor Terekhov.
The capital was under a ballistic missile warning for most of the night, and echoed to the sound of explosions. By morning rescue teams fought fires in residential buildings.
Across Ukraine, Russian attacks once again targeted energy infrastructure and emergency power outages were imposed in several areas.
One MP in Kyiv, Inna Sovsun, told the BBC that the air raids had lasted throughout the night and were definitely an attack on the power supply: “for the majority like myself it means we don’t have electricity and we don’t have water.”
