Russia carried out a large overnight attack on Ukraine using drones and missiles, Ukrainian officials said, in one of the latest salvos of a war that has repeatedly targeted civilian infrastructure.

Authorities in Kyiv reported damage to energy facilities and said the strike caused civilian casualties, though the full scale of the destruction was still being assessed. Emergency crews were working at affected sites as officials warned of further strain on already vulnerable infrastructure.

The assault underscores how energy networks remain a central target in Russia’s campaign, leaving residents exposed to outages and disruption as the war grinds on. Ukrainian officials have repeatedly accused Moscow of using long-range strikes to pressure civilians far from the front line.

Reuters said the attack was launched overnight and involved a combined wave of drones and missiles. Additional details on the damage and casualties were still emerging at the time of reporting.
