Kiev was hit hard in the fresh missile and drone attack which set apartment buildings on fire and killed at least four people. Importantly, Ukrainian officials said a ballistic missile traveling at hypersonic speed hit an "infrastructure facility" near the far western city of Lviv.

Russia's Defense Ministry followed by confirming that it sent an Oreshnik hypersonic missile at "strategic targets" overnight, and specifically described that it was retaliation for the December drone strike on one of the residences of President Vladimir Putin.
