A Russian missile hit a fire department building in the northern region of Kharkiv on Friday, injuring at least eight rescuers, Ukraine's interior minister said.
The attack targeted the town of Izium, the minister, Ihor Klymenko, said in a post on the Telegram messaging app that was accompanied by images of the wrecked building and fire trucks.
"The building itself and 13 pieces of equipment were also damaged," he added but did not say what type of missile had been used.
Five of six drones were destroyed in two waves of Shahed drone attacks that Russia launched overnight on the southern regions of Mykolaiv and Kherson, said Natalia Humeniuk, a spokesperson for the southern military command.
"Unfortunately, there was a hit on an infrastructure object, a fire broke out," she said in comments on televison. "But it is not critical, it was localised."
There were no casualties, she added.
Reuters could not independently verify the reports.
