Air raid sirens have sounded across the whole of Ukraine as Russia launched sustained strikes in several parts of the country hitting power supplies.
Explosions have been heard in the capital Kyiv and the surrounding area, while residents have been urged to take shelter and not ignore alerts.
Kremlin forces struck critical infrastructure in Kharkiv, Ukraine’s second-largest city, and power facilities in Zaporizhzhia.

Sites have also been targeted in Khmelnitskyi in western Ukraine, and the central Dnipropetrovsk region.
While Ukrainian air defences said they had shot down a number of missiles and drones, it was reported Russia had also fired S-300 rockets, which cannot be intercepted.
Zaporizhzhia city council secretary Anatolii Kurtiev said the city had been hit 17 times in one hour, which he said made it the most intense bombardment since the beginning of the invasion last February.
In Kharkiv, authorities were trying to establish the number of casualties and scale of the destruction, with mayor Ihor Terekhov saying there may be disruptions to heating and the electricity and water supply.
