Russian forces struck the city of Kryvyi Rih in Dnipropetrovsk Oblast on July 8, said Oleksandr Vilkul, the head of the city's military administration.
At least 10 people were killed, including six women and four men, according to Vilkul.
Forty-seven people suffered injuries as of 2 p.m. local time, Ukrainian media Suspilne Dnipro reported, citing Yevhen Sytnychenko, the head of the district military administration.
Russia carried out a mass aerial attack on the morning of July 8, targeting the cities of Kyiv, Dnipro, Kryvyi Rih, Sloviansk, and Kramatorsk.
The Russian military used Kinzhal ballistic missiles, as well as Kh-101 and Kh-22 cruise missiles, to attack Ukrainian cities.
Later in the day, Metinvest, Ukraine's private group of steel and mining companies, announced that the workers of its enterprise were killed in the attack on Kryvyi Rih.
Metinvest did not specify the number of casualties in its statement.
"The enemy is openly targeting Ukrainian enterprises that ensure the vital activity of cities, civilians, and our children," the statement read.
"We will never forget or forgive this crime of the aggressor country. It will make us even stronger in our unity and desire to ensure that those responsible for this war and the tragedies in Ukrainian families are brought to justice."
Vilkul earlier reported "several" strikes. One of them targeted an administrative building of an industrial enterprise.
Kryvyi Rih, with a population of around 660,000, is the second most populous city in Dnipropetrovsk Oblast. It has suffered multiple deadly attacks by Russian forces since the outbreak of the full-scale war.
