Russia-Ukraine war: List of key events, day 511

Russia launched overnight air attacks on Ukraine's south and east using drones and possibly ballistic missiles, Ukrainian officials said. The southern port of Odesa and the Mykolaiv, Donetsk, Kherson, Zaporizhia and Dnipropetrovsk regions were under threat of Russian drone attacks. Ukraine's air force said it downed 31 out of 36 Iranian-made Shahed kamikaze drones, all six Kalibr cruise missiles and one reconnaissance drone launched by Russia overnight. Russia's defence ministry said it carried out overnight attacks on two Ukrainian port cities in what it called "a mass revenge strike", a day after an attack on the Crimean Bridge. The ministry said in a statement it struck Odesa and Mykolaiv and hit all targets.
