Video footage showed a devastated building with smoke pouring out of it and rescue workers looking on. Much of the upper floor of what appeared to be a three-storey building had been badly damaged. A covered corpse lay in the road nearby.

"Another (Russian) missile attack, another crime against humanity," Zelensky wrote on Twitter, describing the damage to a psychological clinic and a veterinary clinic in Dnipro.

"Only an evil state can fight against clinics. There can be no military purpose in this. It is pure Russian terror."

Regional governor Serhiy Lysak said a 69-year-old man had been killed, adding: "He was just passing by when the Russian terrorists' rocket hit the city."

The governor said another man's body had been pulled out of the rubble, and that 21 of the 23 wounded had been taken to hospital. Three were seriously hurt, he said.

The Ukrainian Defence Ministry called it a serious war crime under the Geneva Conventions, which set out how soldiers and civilians should be treated in war.

Russia did not immediately comment on the events in Dnipro, a large city that has frequently come under fire since Moscow began its full-scale invasion 15 months ago.
