Russia conducted a large-scale overnight assault on Ukraine, utilizing hundreds of drones, dozens of missiles, and for the second time, its Oreshnik hypersonic ballistic missile. Ukrainian officials reported at least four deaths and 25 injuries, with targets including critical infrastructure and drone production facilities. Russia stated the strike was retaliation for an alleged Ukrainian drone attack on President Putin's residence, a claim Ukraine denies. The Oreshnik, described as capable of speeds around 13,000 km/h and potentially carrying multiple warheads, has raised concerns about escalation.
