Ukraine power grid attack a response to UK-US weapons, says Putin

President Vladimir Putin has said Russia struck Ukraine overnight with 90 missiles and 100 drones in response to Ukraine's attacks with UK and US-supplied weapons last week.

The co-ordinated assault unfolded over several hours with waves of drones and missiles flying across the length and breadth of Ukraine - the second attack of its kind this month.

Ukraine's President Volodymyr Zelensky said cluster munitions were used specifically against civilian and energy infrastructure.

More than one million people in Ukraine are without electricity following Russia's "massive strike".
