Russian missiles have hit Ukraine’s biggest cities, leaving at least five dead and dozens hurt, after Vladimir Putin vowed to intensify attacks.
A woman was killed and 44 others were hurt in the north-eastern city of Kharkiv, according to local officials.
Kyiv Mayor Vitaliy Klitschko said two people died and 49 were wounded in a strike on blocks of flats in the Solomianskyi district of the capital.
Two more deaths were reported in the broader Kyiv region.
There have been major aerial assaults by both sides in recent days.
Russia launched its biggest aerial bombardment of the war late last week, killing more than 40 people. Ukrainian forces responded with an attack on the Russian border city of Belgorod on Saturday, which killed at least 25 people and injured more than 100.
Russia’s Vladimir Putin vowed that attack would not go unpunished and Ukraine’s President Volodymyr Zelensky said since Sunday alone, Moscow had fired 170 drones and dozens of missiles.
Ukraine’s air force said on Tuesday that it had downed 35 drones launched by Russia on Monday night. Russian strategic bombers then followed up the drone strikes with further attacks.
Ukraine’s armed forces said after the drone strikes 99 missiles of various kinds had been fired in a repeat of last Friday’s onslaught, from sea and air. They said 72 cruise and supersonic missiles had been destroyed.
Poland said it had deployed four F-16 fighter jets to secure its airspace in light of Russia’s “long-range aviation activity”. Last Friday Poland said an unidentified object, probably a Russian missile, had entered Polish airspace for several minutes before turning back towards Ukraine.

Kyiv officials said debris from Russia’s attacks had hit high-rise flats, warehouses and supermarkets, and that two people including an elderly woman had been killed by a missile in the Solomianskyi district to the south-west of the Centre.
