A Russian missile hit a clinic in the eastern Ukrainian city of Dnipro on Friday, killing at least two people and wounding 23 in an attack that President Volodymyr Zelensky described as a crime against humanity.
He denounced the attack as a crime against humanity, and 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.
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-story building had been badly damaged, as had cars parked nearby.
"Russian terrorists once again confirm their status of fighters against everything humane and honest," Zelensky wrote on the Telegram messaging app.
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.
Russia has denied repeated accusations that its soldiers have committed war crimes in Ukraine.
Russia, which launched its full-scale invasion of Ukraine 15 months ago, did not immediately comment on the reported air strikes but said Ukraine had struck two regions in southern Russia with a rocket and a drone.
"Missile attack on Dnipro. 'Rashist' b******S attacked a medical facility. There are victims," regional governor Serhiy Lysak said. said on the Telegram messaging app, using a derogatory term for Russians.
