Russian officials announced the use of a hypersonic Oreshnik missile in an overnight wave of strikes on sites they described as energy and drone-manufacturing facilities. The Defence Ministry said the action was a response to what it called an attempted Ukrainian drone attack near a presidential residence in late December.
