KYIV: Air-raid sirens blared across Ukraine on Wednesday, local officials said, but there was no immediate word of a new wave of Russian attacks.
Russia has carried out a series of missile and drone strikes on Ukrainian energy infrastructure since mid-October, knocking out power and causing emergency blackouts in many areas.
