Russia launched about 200 missiles and drones at Ukraine overnight on Monday, in what appeared to be the biggest attack on the country in weeks.
At least five people have been killed and dozens injured due to the strikes, which caused significant damage to Ukraine's energy sector in at least 15 different regions - more than half the country.
Responding to the barrage of drones, cruise missiles and hypersonic ballistic Kinzhal missiles, President Volodymyr Zelenskyy said it was "vile" and claimed the attack had targeted civilian infrastructure.
Ukraine's prime minister Denys Shmyhal added there was damage in a number of regions and that Ukraine's state-owned power grid operator, Ukrenergo, has been forced to implement emergency power cuts to stabilise the system.
