Russia accuses Ukraine of the attack that, among other things, hit a luxury residential building in Kazan, about 100 miles from the front in Ukraine.
No deaths have been reported after the attack.
Whoever it is, and no matter how much they try to destroy, they will face many times more destruction themselves and will regret what they try to do in our country, says Putin.
The statement came on Sunday during a televised meeting with the local leader in the region of Tatarstan, where Kazan is located.
Ukraine has not commented on the attack in Kazan.
Putin has previously threatened to attack central Kyiv as retaliation for Ukrainian attacks within Russia.
