Oct. 10 (UPI) -- Electric power supply was restored to more than a quarter of a million residents of Kyiv on Friday after massive Russian drone and missile attacks overnight targeted energy infrastructure across the country.

Russian forces launched more than 450 drones and 30 missiles, causing power outages in nine regions and killing a child and injuring 24 other people, according to Ukrainian President Volodymyr Zelensky and officials in Kyiv, Zaporizhzhia and Dnipro.

The attacks forced authorities to shut off the power grid in several regions despite Ukrainian air defenses downing or disabling most of the drones and around half of the missiles, which included Kinzhals, an air-launched "hypersonic" weapon capable of speeds in excess of 7,800 mph.

The assault on Kyiv began with waves of drones shortly before midnight, escalating to ballistic and cruise missile strikes in the early hours.
