The attack damaged several residential buildings and an industrial facility, regional governor Ivan Fedorov said in a post on the Telegram messaging app.
"First, there were two missile strikes, and then, about 40 minutes later, there were other strikes at the same place - just as rescuers, police started working," Fedorov wrote, as quoted by the Reuters news agency.
A nine-year-old boy and two journalists were among the wounded, according to officials.
Ukraine's northeastern Kharkiv region was also under intense air attack on Friday, Reuters reported, citing local media and regional officials.
