Residential buildings were hit early on Tuesday in the north-eastern city of Kharkiv, leaving four people killed and another 42 injured.
They included two women of 40 and 56.
The city mayor said part of a block of flats was destroyed and rescue workers were combing the rubble for survivors.
In Kyiv, officials said a woman died and several other people were hurt when a block of flats caught fire and another was damaged.
Most of the casualties were in Kyiv’s central Solomianskyi and western Sviatoshynskyi districts.
The BBC’s Sarah Rainsford said the air raid in Kyiv went on for more than two and a half hours, the longest since 2 January.
