Russia launched a large-scale overnight attack on Ukraine, utilizing hundreds of drones, dozens of missiles, and for the second time, its nuclear-capable Oreshnik hypersonic missile. Officials reported at least four deaths and 25 injuries in Kyiv, with damage to infrastructure and the Qatari Embassy. Russia stated the strike was retaliation for an alleged Ukrainian drone attack on Putin's residence, a claim Ukraine and the US deny. Ukraine and European allies condemned the Oreshnik's use as an escalation and a warning to the West, urging increased air defense support.
