KYIV, Ukraine (AP) — One of Ukraine's largest drone strikes on Russia killed at least four people, including three near Moscow, and wounded a dozen others, local authorities said Sunday. Debris fell on Russia's largest airport without causing damage.

Ukrainian President Volodymyr Zelenskyy confirmed the drone strikes, saying that they were “entirely justified.” Russia has repeatedly launched similar attacks on Ukraine's capital and other cities during the war, and an expert said that the strikes appeared to be retaliation for recent Russian attacks on Kyiv.
