Russian overnight attacks on Kyiv, the capital of Ukraine, killed four people and injured 22 others, Ukrainian officials said. President Volodymyr Zelensky said residential buildings, civilian infrastructure, energy facilities, and the Qatari Embassy were damaged, with a second strike hitting as rescuers were working. Zelenskyy said Russia used hundreds of drones and multiple missiles nationwide and called on allies, especially the United States, to strengthen Ukraine’s air defense.
