A missile strike seriously damaged a key energy facility in Ukraine's capital region, the country's power system operator said Saturday as the Russian military strove to cut water and electricity in populated areas.
Kyiv region Governor Oleksiy Kuleba said the strike did not kill or wound anyone.
Electricity transmission company Ukrenergo said repair crews were working to restore power but warned residents about possible outrages.
It comes as Mr Putin, who has said he would be ready to use nuclear weapons to defend Russia’s “territorial integrity”, warned that a direct clash with Nato troops is a “very dangerous step”.
When asked if he had any regrets in relation to the conflict he said “no” and insisted Russia was doing the right thing.
The Kremlin also said he believed the “partial mobilisation” of army reservists ordered last month would be completed in two weeks, boosting Russia’s fighting force.
