Russian forces launched a mass drone attack on the southeastern Ukrainian city of Dnipro late on April 29, killing one person and setting several homes on fire, the regional governor said.
"Dnipro residents remember last night as hell," Serhiy Lysak said on Telegram.
"[A person] was taken out and put on the grass and put in a black bag.... He was killed," a Dnipro resident told RFE/RL at the scene of the attack on the morning of April 30.
Earlier, Russian drones also struck Ukraine's second-largest city, Kharkiv, regional Governor Oleh Synyehubov said, adding that dozens of people had been injured, including two children and a pregnant woman.
The youngest injured was 5 years old, according to Ukrainian President Volodymyr Zelenskyy.
"Residential neighborhoods were hit, with apartment buildings, a hospital, and a school damaged," he added.

Deadly Russian Drone Strikes Hit Kharkiv And Dnipro
Meanwhile, a source from the Ukraine's Security Service (SBU) told RFE/RL that it was responsible for a drone strike on a Russian defense manufacturing facility in the Vladimir region.
According to a source in the SBU, the Murom Instrument-Building Plant, located 300 kilometers east of Moscow, specializes in the production of ammunition fuses, components, and products for the Russian Navy and military aviation.
"The Murom Instrument-Building Plant is on the sanctions lists of Ukraine and the EU because it plays a significant role in ensuring military aggression against Ukraine," said the source, who asked to remain anonymous.
Earlier, the ASTRA Telegram channel, citing sources in the Russian Emergencies Ministry, reported that a warehouse and a gatehouse of the facility had burned down.
