President Vladimir Putin on Thursday threatened to strike "decision-making centres" in Kyiv with Russia's new hypersonic missile, hours after Moscow pummelled Ukraine's energy grid in an attack that left a million people without power.

He added that decision-making centres in Kyiv could become a target for Oreshnik - the new ballistic missile Russia used to attack the Ukrainian city of Dnipro last week. Russian President Vladimir Putin has said that Russia struck Ukraine with 90 missiles and 100 drones overnight in response to Ukraine's attacks with UK and US weapons last week.

Russia may use its new Oreshnik hypersonic missile to attack "decision-making centres" in Kyiv in response to Ukraine's firing of Western missiles at Russian territory, President Vladimir Putin said on Thursday.
