The attack on Friday, which killed at least four people nationwide, came two days after Russia vowed retaliation for an audacious drone assault on its strategic bomber bases.

Officials say Ukraine was under an ongoing Russian ballistic missile and drone attack early Friday that wounded at least three people.

A Russian drone and missile attack on Kharkiv resulted in three deaths and 21 injuries. The assault damaged multiple buildings and utilized 48 drones, two missiles, and four glide bombs, highlighting the ongoing conflict's escalation amid stalled peace efforts.
