Overnight, Moscow's missile and drone strikes have led to electricity outages in multiple districts of Ukraine's capital, Kyiv.

Authorities reported that numerous aerial vehicles and more than 30 missiles targeted the country's power systems, describing such attacks as "cynical and calculated" and against "everything that sustains normal life" as the weather cools.
