Russia strikes six major power substations and railways across Ukraine, injuring at least 14

At least 14 people were injured in the attacks, according to the prime minister.

The six substations were targeted in Vinnytsia, Kirovohrad, Zhytomyr and Cherkasy oblasts in central and northern Ukraine.

Power transmission lines of various voltage levels were also damaged in Kirovohrad and Rivne oblasts.

In Kryvyi Rih, a city in southeastern Ukraine, a Russian strike hit a district heating facility, disrupting heat supplies to residential buildings. Repair crews were working to restore service, Koretskyi said.

Russian forces also struck railway infrastructure in Dnipropetrovsk and Zhytomyr oblasts.

Elsewhere, an aerial bomb strike damaged a school building in the southern Kherson region, while five apartment buildings were damaged in Kharkiv, Ukraine's second-largest city.

The prime minister said at least 14 people had been injured and were receiving medical assistance. He did not provide a breakdown of casualties by location.

The attacks come as Ukraine continues to face Russian strikes on its energy infrastructure ahead of winter, raising concerns about the reliability of electricity and heating supplies.
