The city of just under one million people came under attack from a missile and four groups of drones approaching from the south, east and north, Ukraine Air Force said on the Telegram messaging app.

Ukraine's largest private energy provider, DTEK, said that a thermal power plant was significantly damaged. There were no casualties, it added.

The company did not say where the power plant was located, but Dnipro's water utility company said on Telegram that "due to power outages" water supply had been partially suspended and Ukrainian media outlets said a power plant in Dnipro was hit.

Dnipro Mayor Borys Filatov said infrastructure had been hit, but gave no further details.

Reuters was not able to independently verify the reports. There was no immediate response from Russia's defence ministry to a request for comment.

Both Russia and Ukraine have increased their air attacks away from the frontline in recent months, targeting each other's critical energy, military and transport infrastructure.
