President Vladimir V. Putin of Russia says his country will continue targeting Ukrainian cities in retaliation for a deadly attack on the city of Belgorod on Saturday.
Moscow said that it had struck Kharkiv with missiles in retaliation for what it said was a deadly Ukrainian air assault on the Russian city of Belgorod.
The bombardment of Belgorod on Saturday, apparently in response to an enormous air assault by Moscow a day earlier, appeared to be the deadliest on Russian soil since the beginning of the war.
Attacks from Ukraine have killed at least a dozen Russian civilians and displaced thousands. But they have not fundamentally changed the calculus for Vladimir Putin.
