Russia’s widespread overnight attack targeting critical energy infrastructure facilities in Ukraine was a response to strikes on Russian territory using US-made ATACMS missiles, President Vladimir Putin said Thursday.

Russian forces launched more than 180 drones and missiles at Ukraine, successfully hitting 12 sites of fuel and energy infrastructure, according to the Air Force. Energy Minister Herman Halushchenko said that Russia struck a "massive blow" at Ukraine's power grid. Emergency blackouts were introduced in multiple regions across Ukraine.

Russian attacks have not so far struck government buildings in the Ukrainian capital. Air defences heavily protect Kyiv, but Putin says Russia’s Oreshnik hypersonic missile, which it fired for the first time at a Ukrainian city last week, is incapable of being intercepted.
