Russia has launched the largest attack on Ukraine's energy infrastructure since the spring, primarily targeting Kyiv and the surrounding region, Ukraine's Prime Minister has said. At least five people were killed in overnight attacks across the country, including a child in the Kyiv region, Serhiy Koretskyi said.

The strikes also impacted people's power supplies, with Ukraine's biggest private energy firm DTEK saying power to 8,000 homes had been restored following "a difficult night" for the capital. The Russian defence ministry said one of its targets was the Trypilska power station, the largest supplier of electricity to Kyiv.

The operator confirmed damage to the plant. Koretskyi wrote on Telegram: " Since the summer, there has effectively not been a single day without enemy attacks on our energy infrastructure.

" However, a mass and combined attack of this scale has occurred for the first time since the end of the last heating season." Ukraine has been expecting another protracted Russian assault on the country's energy grid.

It has happened every winter so far since Russia's full-scale invasion began in 2022. In total, 11 regions of the country were attacked overnight, with residential buildings, social infrastructure, civilian enterprises and railways also targeted, Koretskyi said.

Ukrainian President Volodymyr Zelensky said there had been strikes on critical infrastructure in the Zhytomyr, Mykolaiv, Kirovohrad and Rivne regions. On Wednesday, some households in the Kyiv, Dnipropetrovsk, Donetsk, Sumy and Kharkiv regions remained without power, Ukraine's energy ministry said.

State-owned grid operator Ukrenergo advised residents not to use powerful electrical appliances between the hours of 10:00 and 16:00 local time as electricity supplies were lower than usual. In Kyiv, people woke to find the city blanketed by thick, acrid smoke after a night punctuated by the sound of explosions.

An air raid alert was still on and the distant sound of air defence gunfire echoed through the murky atmosphere. Residents in several districts were advised to close their windows until the smoke cleared.

Among those killed in the overnight strikes was a child whose body was found under the rubble of a house, Kyiv regional head Timur Tkachenko said. Kyiv Mayor Vitaly Klischko said three people were killed in total in the capital, including a Ukrainian utility company worker who was killed at a warehouse building.
